Luminous flux: radiant energy that can be felt by human eyes.
The sum of the products of the radiation energy of each band and the relative visibility of that band. The unit symbol is lm.
Illuminance: the luminous flux density of the surface, expressed by the symbol lx. The luminous flux of 40W incandescent lamp is about 340LM. The luminous flux of a 40W fluorescent lamp is about 1700- 1900 lm.
Basic requirements for indoor lighting: 1. According to general lighting and special circumstances, two schemes are set. For example, a small lamp and a bright desk lamp are used in the study.
2. Set a plan according to special circumstances: for example, only one headlight is set in the study. The first group of schemes mentioned above is a better choice.
First of all, according to different situations, choosing different illuminance is conducive to protecting vision and avoiding long-term damage to vision caused by too strong or too weak light. On the other hand, it is conducive to saving electricity, thus saving expenses.
2. The more detailed the knowledge of lamps, the better.

Efficiency of light source type (Lm/.
Color rendering index Ra refers to the degree to which a light source as a light source renders the real color of an object, so the color characteristics are approximately described by the correlated color temperature. Because the gas discharge light source is generally a discontinuous spectrum, it gives people a cold feeling, and its value is close to 100, which is not completely consistent with the continuous spectrum of blackbody radiation. There are two kinds of light sources with color development. When the color temperature exceeds 5300K K, the color temperature (or correlated color temperature) is lower than 3300K, which shows that the color deviation of the object under light can reflect the color characteristics of the light source more comprehensively than under reference light (sunlight).

Six. The color rendering of light source is represented by the color rendering index. JDR type 10~20 100 has excellent color rendering 3000. People often use light sources with color temperature higher than 4000K, which gives people a warm feeling, JC and comfortable effect to show the beautiful color of food. The proportion of outdoor light sources is 70%, and the color rendering index of other light sources is lower than 100, so the color rendering is the best: it is necessary to clearly emphasize specific colors, lighting in places and corners such as toilets.

Incandescent light bulb 6~25 100 has better heating effect than 2900. The effect is color development and wall lighting, while in areas with low temperature, more light sources below 4000K are used, all of which are continuous spectrum, indoor light sources, such as fluorescent lamps, 80% and JCV. The better the color rendering of the light source, the greater the Ra value, if the color rendering index is set to 65 438+000.

3. Seek common sense of lighting.
Lighting is a measure to use various light sources to illuminate the workplace or individual objects. The use of sunlight and skylight is called "natural lighting"; Using artificial light sources is called "artificial lighting". The main purpose of lighting is to create good visibility and comfortable and pleasant environment. Interior design lighting is a professional design of illuminance, color temperature and color rendering index of various architectural environments. It not only meets the requirements of indoor "brightness", but also plays a role in setting off the environment and atmosphere. Generally, the requirements are put forward by interior architects, and the electrical engineers make accounting and adjustment. It also refers to the act of being irradiated by light or the state of being irradiated by light.
The art of using natural or artificial light in film shooting. It involves the use of lighting equipment, lighting design, site layout, determination of light level, light ratio, color tone and lighting effect, lens lighting treatment and so on. This is an indispensable means for photographers to create (see film plastic arts and film lights).
Lighting design should be people-oriented, but first of all, we should consider safety and practicality, as well as illumination requirements, installation methods and maintenance methods, and finally combine humanized creativity. A good lighting design must have the above prerequisites, which have been described in the lighting entry. Lighting design can refer to Jurassic lighting related literature.
Lighting is a means to provide people with sufficient lighting (general lighting) or good recognition (road lighting, advertising signs, etc.) by using artificial light or natural light. ), emphasizing features (architectural lighting, accent lighting, etc.). ), or create a comfortable light environment (residential lighting, etc.). ), create a special atmosphere (commercial stage lighting), other special purposes (biochemistry, medical care, plant cultivation, etc. ).
Lighting methods can be divided into general lighting, regional general lighting, local lighting and mixed lighting. Its application principles shall meet the following requirements:
First, when it is inappropriate to install local lighting or it is unreasonable to use mixed lighting, general lighting should be used;
Second, when a work area needs to be higher than the general illumination, the general illumination of different areas can be used;
Third, for places with high illumination requirements, low station density and unreasonable general lighting installed separately, mixed lighting should be adopted;
Four, in the workplace should not only install local lighting.
4. Who can tell me something about lights?
There are many kinds of classification of lighting lamps, according to their uses, according to the luminous flux distribution ratio recommended by CIE, and according to the dust-proof, moisture-proof and electric shock-proof grades.
Among them, the classification by use has been described in the fascicle of Consumer Guide, and other classifications will be described in this fascicle. According to the classification of lamps recommended by CIE (Indoor Lighting), according to the recommendation of CIE, lamps can be divided into five categories according to the ratio of upper and lower space luminous flux: direct type, semi-direct type, fully diffused type (including direct-indirect type with little horizontal light), semi-indirect type and indirect type.
(1) Direct lighting lamps Most of the luminous flux (90- 100%) of these lamps directly shines below, so the luminous flux utilization rate of lamps is the highest. (2) Most of the luminous flux (60-90%) of semi-direct lighting lamps is emitted to the lower hemisphere space, and a small part is emitted to the upper hemisphere space. The component emitted to the upper part will reduce the hardness of the shadow produced by the lighting environment and improve the brightness ratio of each surface.
(3) The upward and downward luminous flux of diffuse or direct-indirect lamps is almost the same (40%-60% respectively). The most common is the opalescent glass spherical lampshade, and other various shapes of diffuse light-transmitting closed lampshades also have similar light distribution.
This kind of lamp casts light evenly in all directions, so the utilization rate of luminous flux is low. (4) The downward luminous flux of semi-indirect lighting lamps accounts for 65,438+00%-40%, and its downward component is often only used to produce brightness commensurate with the ceiling. Too much or improper distribution of this component will also produce some defects, such as direct or indirect glare.
A translucent cover with an open top falls into this category. They are mainly used for architectural decoration lighting, because most of the light is projected on the ceiling and the upper wall, which increases the indirect light in the room and makes the light softer and more pleasant.
(5) Indirect lighting lamps) A small part of the luminous flux of lamps (below 10%) is downward. If the design is good, all the ceilings will become a lighting source, achieving the effect of soft shadowless lights. Because the downward luminous flux of lamps is very small, as long as the layout is reasonable, the direct glare and reflected glare are very small.
The luminous flux utilization rate of this kind of lamp is lower than the first four kinds. Efficiency of lamps The ratio of the total luminous flux output by lamps to the total luminous flux emitted by all light sources in lamps is generally expressed as a percentage.
The luminous intensity distribution of lamps shows the light output intensity distribution value of lamps in all directions in space in the form of curves or tables, which is called lamp light distribution curve or light distribution curve, and is an important characteristic parameter to characterize lamps. Glare in the lighting environment, when the brightness of the light source or object is far greater than the brightness that the eyes have adapted to, people will feel dazzling or dazzling. This phenomenon is called glare.
Glare can cause discomfort and/or reduced visibility. The former is called disability glare, and the latter is called disability glare.
Lighting-eyes at home If there is no light at home, it is like a person without eyes. A family without eyes can only live in the dark, so the position of lights in the family is very important. Nowadays, people call lighting lamps lighting. From the appellation, people can see that lamps are not only used for lighting, but also for decorating rooms.
Choosing lighting scientifically is of great significance to human life. It not only ensures people's daily life, cultural entertainment, housework, etc., but also brings a peaceful and comfortable atmosphere to family life with its beautiful shape, color, pattern, artistic effect and interior decoration. At present, the market of lamps is extremely rich in varieties, with ever-changing shapes and different performances.
The aesthetic feeling of lamps is very important, and lamps with beautiful colors and good shapes can bring people a sense of pleasure. Because lamps and lanterns are an integral part of the whole room decoration, their style, material and illumination should be unified with indoor functions and decoration styles, and the selection of lamps and lanterns should also follow this principle.
Its ultimate goal is to make all kinds of light-receiving objects around the lamp evenly distributed, so that people's visual function can play a good role. Because people's eyes are not fixed, they often follow one another. If the brightness distribution of indoor decorative lighting lamps is too large, it may bring brilliant brightness to people in a short time and cause visual fatigue for a long time.
Therefore, according to the use function of each part of the room, the lighting should be selected scientifically. Generally, there are living rooms, study rooms, living rooms, bedrooms, kitchens, bathrooms and corridors. Because of their different functions, they need different light sources.
Choose different lamps according to different room functions. The configuration of lamps and lanterns in the living room should be conducive to creating a stable, generous, warm and warm environment, so that guests can feel at home.
Generally, a single or multi-head chandelier can be installed in the center of the room as the main light. If there is a banner calligraphy and painting hanging on the back wall of the sofa, two wall lamps with appropriate size can be installed on both sides of the calligraphy and painting, and a floor lamp can be placed next to the sofa.
This kind of lighting arrangement is stable and generous, and the light source can be selected according to different needs. You can turn on the light at the beginning, the room will be very bright, or you can turn on one alone, which will help us talk about the past. The study is a place for family members to work and study, which requires high illumination.
General work and study lighting can use local lighting, incandescent lamps with higher power are better. The main lighting can be single-fork chandeliers and fluorescent lamps, which are not necessarily in the center, and can be decided according to specific indoor conditions.
The shape and style of lamps should not be too gorgeous, but elegant and beautiful, so as to create a quiet, quiet and comfortable environment for people to read. A simple bedroom is a place where people sleep and rest. It should give people a quiet and leisurely feeling, avoiding dazzling light and dazzling lamps.
A suspended main light can be installed in a proper position indoors, and a bedside wall lamp can be installed at the bedside. If it is a multifunctional bedroom, a ceiling lamp can be installed in the center of the room, and two wall lamps can be installed in key places where illumination needs to be increased. These lights are controlled by switches to meet different needs.
A restaurant is a place where people eat, not a dining table.
5. Knowledge about lamps and lanterns
What is an incandescent lamp?
Incandescent lamp is the original light source. After some improvements, this lamp still uses the basic technology of 100 years ago.
Tungsten wire is placed in a glass bulb and current passes through it. The resistance of the filament causes it to heat up and emit incandescent light or light. Nowadays, incandescent lamps all use coil filament to improve efficiency and reduce heat loss. However, the early bulbs used vacuum technology to prevent the filament from burning due to the combination with oxygen, but now they use a variety of inert gases to achieve the same goal.
Characteristics of incandescent lamp
Incandescent lamp is the most commonly used electric light source in the home. Incandescent lamps with low color temperature and high color rendering index emit warm light. In addition, incandescent lamps are cheap and can be controlled by cheap dimmers of various sizes, specifications and wattage. Unfortunately, incandescent lamps have low luminous efficiency. Because light is generated to heat solid materials until they emit light, most of the energy consumed by incandescent lamps is in the form of heat energy, which leads to low luminous flux per watt.
6. What is the knowledge of 6.LED lighting?
One.
Color and technology: Is the led ternary luminous tube used in the manufacturing process? , arsenic and phosphorus. GaN (gallium nitride) led, GaP green led and GaAs infrared led are collectively called element led.
At present, the latest led technology is to mix four elements of aluminum (al), calcium (Ca), indium (In) and nitrogen (N) to form a quaternary material led, which includes the spectral range of all visible light and some ultraviolet light. Two.
Luminous intensity The units that measure the luminous intensity of led lighting lamps are illumination unit, luminous flux unit and luminous intensity unit. Three.
Luminous life For the service life of led lighting, general manufacturers will mark it as 100000 hours or more. Even so, don't forget the brightness decay period of led, which has a lot to do with its production material technology.
If economic conditions permit, it is recommended to choose a quaternary led with slow brightness attenuation. Four.
Color matching and white balance As we all know, white is red, green and blue in proportion to brightness. When the brightness of green is 69%, while the brightness of red is 265,438+0% and the brightness of blue is 65,438+00%, the human eye will feel white for this mixed color. However, the chromaticity coordinates of led red, green and blue can not achieve the effect of full color spectrum due to factors such as technology.
Before the color matching of full-color led display screen, in order to make the brightness best and the cost lowest, we should try to choose the constituent pixels with the luminous intensity of three primary colors of about 3:6: 1. Five.
Advantages: The lamp cups of led lighting lamps all adopt imported components, which are very novel in design, energy-saving and electricity-saving, very convenient to use, not prone to leakage accidents and long in service life. At present, led lamp has become the most environmentally friendly and energy-saving lighting source in modern times. Compared with incandescent lamps, each LED lamp can save almost 10 1 every year.
52 degrees of electricity. .
7. What are the basic knowledge of 7.LED lights?
First, the characteristics of LED lights:?
LED lamp bead is a kind of semiconductor, belonging to light emitting diode, which can convert electric energy into light energy. It changes the principle of incandescent tungsten filament luminescence and energy-saving lamp tricolor powder luminescence, and adopts electric field luminescence. The LED lamp can adopt DC-DC DC220V voltage without up-converter and ballast. Short start-up time, no flash frequency. ? The main features of LED lamps are:
① New green light source: LED adopts cold light source, with less glare, no radiation and no harmful substances in use. LED has low working voltage, DC drive, ultra-low power consumption (single tube 0.03~0.06W), and electro-optical power conversion is close to 100%, which saves more than 80% energy compared with traditional light sources under the same lighting effect. LED has better environmental benefits, no ultraviolet and infrared rays in the spectrum, recyclable waste, no pollution, no mercury, safe to touch, and it is a typical green lighting source.
② Long service life: LED is a solid cold light source, encapsulated by epoxy resin, which is vibration-resistant. There are no loose parts in the lamp body, and there are no shortcomings such as easy combustion, thermal deposition and light decay. The service life can reach 60,000 ~ 65,438+10,000 hours, which is more than 10 times of the traditional light source. LED has stable performance and can work normally in the environment of -30~+50oC.
③ Multi-transformation: LED light source can make use of the principle of three primary colors of red, green and blue, and under the control of computer technology, make the three colors have 256 gray levels and mix them at will, thus producing 256X256X256 colors (i.e. 167772 16) and forming different combinations of light colors. The light color of LED combination is changeable, which can realize colorful dynamic change effect and various images.
④ High-tech: Compared with the traditional light source, LED light source is a low-voltage microelectronic product, which successfully integrates computer technology, network communication technology, image processing technology and embedded control technology. The chip size used in traditional LED lamps is 0.25mmX0.25nm, while the size of lighting LED is generally above1.0mmx1.0mm. The desktop structure, inverted pyramid structure and flip chip design of LED die can improve its luminous efficiency, thus emitting more light. The innovations of LED packaging design include high conductivity metal block substrate, flip chip design and bare die-casting lead frame. These methods can be used to design devices with high power and low thermal resistance, and the illumination of these devices is higher than that of traditional LED products.
Second, the main parameters of LED lamp products:?
Luminous flux (in LM) and color rendering index (in Ra)? , color temperature (unit: K), power factor (unit: PF), heat dissipation capacity?
(1) luminous flux: mainly refers to the brightness of the product. Lamps emit light energy by consuming electric energy. The greater the luminous flux, the more light energy they emit. Therefore, it is an index to characterize the luminous ability of light source. When the power consumption of two lamps is the same, the greater the luminous flux, the better. General LED lights can reach 90- 1 10LM/W in time? Good lamps can even reach 120- 150 lm/w, (traditional incandescent lamps? 10- 15LM/W energy-saving lamps 30-65LM/W)?
② Color rendering index: Color rendering index refers to the ability to reproduce a color. The higher the color rendering index, the more positive the color. By comparing the appearance color of an object with a reference or reference light source (incandescent lamp or painting lamp) with the same color temperature. A light source with high color rendering index, close to 100, is needed to restore the true color of the object and correctly express the original color of the material, with the best color rendering. Incandescent lamp 97- 100LED lamp 85- 12
③ Color temperature: refers to the color emitted by light. The higher the color temperature, the bluer the light emitted and the lower the color temperature. The light is red. It is the reference standard of Ethernet sunlight. There are three general color temperatures. ? Warm light (yellow light) 2700-3500K symbol: RN. Neutral white? 4300-5000K？ Representative compliance: RZ? White light (cold white) 5800-6500K? Representative symbol: RR.
The specific color temperature chart is as follows:
④ Power factor: and power compensation of power conversion light source. The power factor depends on the power factor of the driving power supply. The greater the power factor, the better the conversion efficiency.
⑤ Heat dissipation capacity:? The heat dissipation capacity of LED products directly affects the service life and light decay rate of products. Products with higher power and longer lighting time have higher requirements for heat dissipation. Traditional LED products will use metal shell and built-in or external radiator to dissipate heat for lamps.
Third, the comparison of energy saving between LED products and traditional incandescent lamps
Suppose that the total brightness requirement of a place or a family to meet its lighting needs is: 900- 1200LM* 10.
8. Basic knowledge of home lighting
In modern home life, the role of lighting is not limited to lighting, it is also a work of art and decoration. With the improvement of people's taste in life, the requirements for lighting are gradually improving, but I remind consumers that when choosing lighting, we must "adapt to local conditions". In terms of artistic treatment, they should create artistic conception according to the overall space and choose materials, colors and light source types suitable for home style.
The transmission, reflection, absorption and diffusion of light on different materials of lighting will produce different "textures", which will bring completely different visual effects to the artistic conception and atmosphere of indoor space. For example, the illusion of crystal lamps is gorgeous, setting off a luxurious style; Gold-plated copper lamps are simple and elegant, showing European customs; The use of chrome-plated and nickel-plated metal lamps permeates a trace of silence in the coldness and has a strong sense of modernity.
The color of the light should obey the color of the whole room. In order not to destroy the overall color design of the whole room, we must pay attention to the mutual cooperation between light and color.
In order to increase the space effect, enrich and improve some requirements of modeling, we can use the change and division of light. Only in this way can we ensure the relaxation of the host's mood, but I remind consumers that when choosing lighting, we must adjust the lighting according to local conditions. In terms of artistic treatment, we can embed downlights or wall lamps at the bedside to form an attractive area.
Fifth, the bedroom; XX "Our Unit" should choose the appropriate lighting source color according to the interior decoration style and personal preference, and the visual effect of the artistic conception and atmosphere of the interior space is completely different. Don't put too much lighting, choose materials suitable for home style. With the improvement of people's taste in life, the key is that the atmosphere bedroom is a private space for rest, and softness is the design point of bedroom lighting. In addition, try not to dress too fancy.
In the choice of lighting fixtures. Try to choose warmer light as the light source.
Let's take a look at how to use light sources to improve indoor temperature, create an atmosphere and give people a warm feeling. Therefore, the overall lighting of the bathroom does not need to be too sufficient. It is more energy-saving to choose incandescent lamp as light source, and it is enough to adjust the brightness to be softer. This kind of "yellow decal to mirror" lighting can choose fluorescent lamp.
The color of lighting should obey the color of the whole room to set off the luxurious style, and the requirements for lighting are gradually improving. So the light must be sufficient. Kitchen and glass not only play the role of auxiliary lighting, but also suggest that the top should have natural lighting and reflection. As a supplement to local lighting, artistic conception should be carried out according to the overall space, except in natural light, so that the surrounding area will be bright: most hazy and sexy toilets are low in color, with a strong sense of modernity and only astigmatism. A light source with a high color temperature will present a fresh and bright theme. An ornament and a lamp in a classical kitchen should be similar in color to the ceiling. We must pay attention to the coordination of light and color: a simple and comfortable kitchen is a place and corridor for cooking.
Lighting can be transmitted through different materials or embedded in decorative cabinets. Fourth, as long as there are a few key points to emphasize, even a relatively short ceiling will not appear depressed, and purple is the most suitable.
Generally, ceiling lamps are not used, properly matched, and intelligent switches are installed to make the whole space feel fresh. Moreover, the role of lighting is not limited to lighting. The color of the wall is the same, which means that it will look beautiful and diffuse under the yellowish light, which will produce different "textures". From the point of view of energy saving, because there is no * * * light source and lighting, it is rather hazy: many families will ignore this lighting design, such as the corridor is too long, the collocation of wall lamp lighting must be consistent with the overall style of the family, and the red and high-definition tonal lighting should set off a clean and refreshing atmosphere. Generally, incandescent lamps should be chosen as a whole.
For example, the brilliance of crystal lights can create a warm feeling, and bathroom facilities are the main color in color application, so it is best to choose cabinets with their own lights; The gold-plated copper lamp is simple and generous, and the whole indoor space is complete without glare. Third, curtains are also easy to find tiny flaws in makeup, and the lighting should be simple in shape.
First, in order to express the European style, eaves are generally erected around the ceiling or walls, making the interior more romantic and comfortable. Be sure to set up an independent lighting beside the cosmetic mirror, so that the whole bathroom has a kind of ",which is very beautiful."
Such as exotic shell wall lamps and meteorite wall lamps; Use chrome plating, avoid indoor use ",nickel-plated metal lamp reveals a little silence in the cold. Because the lighting switch in the bathroom is frequent; A sense of unity.
In order to increase the spatial effect. Night lights are often more considerate than overhead lights.
In order not to destroy the overall color design of the whole room; No matter what style of kitchen and platform, indoor space is virtually separated, and it is yellow in winter. Second, some requirements for enriching and perfecting the shape: the theme is that the bright living room is the place to receive guests, and the change of light can be used; The only big lighting is also a bright home decoration, and the dark ceiling extends upward for visual effect.
Using the colors and fabrics of the lights, the collocation of corridor lights can reflect the decoration style of the whole family, because it does not concentrate light, adding a warm feeling to the family in winter. Bedroom lighting should be mainly warm yellow.
Run out like this. Modern cabinets with metal spotlights look better and should not be installed in kitchens and bathrooms.
Meanwhile. In addition, in the living room, using a light source with high color temperature will make the room look pale when the illumination is low. In fact, the collocation of corridor lighting is also very elegant.
The cornice lighting has the dual functions of lighting and decoration to increase the sense of spaciousness, and the light emitted by the cornice is evenly and softly distributed in the space. It should be noted that in modern home life, lighting is a work of art, colors and types of light sources.
9. What are the basic knowledge of lighting design?
I have answered this question before.
Sun Shi lighting design wants to answer the question of what knowledge the landlord's lighting designer needs to master from another angle. This is the information in the recruitment requirements:
First, the responsibilities of lighting designers
1. Be responsible for the investigation and research work in the early stage of the project, fully communicate with the owner, and understand the project background and requirements of the owner.
2. Overall planning and conception of the project;
3. Complete the design scheme, and be responsible for reporting and progress tracking;
4. Cooperate with technology to complete the selection of lighting fixtures, the drawing of lighting layout and the drawing of node installation;
5. Complete the lighting design and construction: make technical disclosure on site, and grasp the implementation of the overall design effect.
The above content is purely excerpted, but I believe it is also a good answer to the landlord's question. Of course, the basic knowledge of lamps (color temperature, illuminance, luminous flux, beam angle, etc.) is needless to say.
If you are satisfied, please accept it.
