1, face light: from the audience on top of the front of the light thrown onto the stage, the main role of the character front lighting and the whole stage basic light pavement coloring.
2, ear light: located on both sides of the stage outside the mouth, diagonally thrown on the stage light, divided into the upper and lower layers, the main auxiliary face light, strengthen the facial lighting, increase the characters, scenery, three-dimensional sense. 3, column light (also known as side light): from the mouth of the stage on both sides of the projected light, mainly used for characters or scenery on both sides of the face lighting, to increase the sense of three-dimensionality, sense of contour.
4, the top light: from the stage above the light thrown onto the stage, from front to back is divided into a row of top light, two rows of top light, three rows of top light ...... and so on, mainly used for the stage general illumination, to enhance the stage illumination, and there are many scenes, props, fixed-point irradiation, mainly rely on the top light to solve. 5, backlight: from the stage in the opposite direction of the light projected (such as the top light, bridge light and other reverse irradiation), can outline the characters, scenery said the outline, enhance the sense of three-dimensionality and transparency, can also be used as a specific light source.
2. What are the skills of light use
1.
The use of the car width signal lamp (small lamp) The car width signal lamp is commonly known as small lamp, is used to show the width of the car and the location of the signaling device. Generally set in the front of the car on both sides of the headlights on one side of a white light, in the rear of the car is set on both sides of the body of the red light, and the license plate light with the same light.
The use of methods are as follows: (1) the car at night when the street lamps are well lit, enter the city, even if the street lamps are very bright neighborhood driving or temporarily parked by the side of the road, do not turn off all the lights, should be retained wide lights. (2) In rain, snow, fog or evening when the light is dark, you should turn on the signaling lamps to indicate the passing cars, pedestrians, the width of the road occupied by the car.
(3) Parking on the side of the highway at night, especially after the rain, the whole rear of the car is covered by the mud and water rolled up by the rear wheels, and the color of the ground is close to the time, it should be more open to show the wide lights or emergency lights, to the passing cars, pedestrians to send signals, so as to avoid cuts or collision. 2.
The use of emergency signal lights Emergency signal lights work, the front and rear four turn signal lights flash at the same time, the driver in the following cases shall open the emergency signal lights, other cars should pay attention to avoid: (1) the car breaks down on the side of the road. (2) The car has a traffic accident.
(3) The car was forced to stop on the highway emergency stopping zone due to failure. (4) To carry out urgent business or special duties.
(5) In case of rain, snow, fog, etc., visibility is low during the day. (6) Convoy driving.
3. The use of the reverse signal light The reverse signal light is a small white light set in the rear of the car, when the car gearshift lever into reverse gear, the reverse signal light is then opened, its role is to prompt other cars, pedestrians to pay attention to avoid.
4. The use of brake signal lights Brake signal lights are used to prompt the rear of the car to slow down the red signaling device, some set up in the rear of the car on the left and right sides, and some set up with the tail lights, when the driver stepped on the brake pedal when the tail light brightness increased.
5. The use of turn signals (1) to the left turn, change lanes to the left, ready to overtake, drive away from the parking place or turn around, you should turn on the left turn signal in advance, as shown in Figure 1-46.
(2) to the right turn, change lanes to the right, overtaking finished back to the original lane, pull over to the side of the road, you should turn on the right turn signal in advance, as shown in Figure 1-47. (3) the use of turn signals Note: 1) General plane intersection.
The car to the general plane intersection, according to the width of the road surface, the size of the traffic flow and the driving speed at the time, 30?100m from the intersection of the place, according to the direction of the turn on the turn signal. Intersections with guide lanes, should be turned on before entering the guide lanes.
2) Circular intersection. When a car enters a circular intersection, the turn signal may not be turned on.
The right turn signal should be turned on when the vehicle is leaving the intersection. (3) The turn signal should be turned on at a good time, should be turned on 30-100 meters from the turning intersection.
Turn on too early will give the car behind the illusion of "forget to turn off the turn signal", turn on too late will make the back of the trailing vehicles, pedestrians are unprepared for, busy in the wrong.
The use of headlights (commonly known as headlamps) (1) When the opposite side of the oncoming traffic, you should turn off the high beams and use the low beams. (2) When driving at dusk, it is better to turn on the headlights later rather than earlier.
If you turn on your high beams or low beams in advance, you will dazzle the other side of the car, and also affect your vision. But in the more bumpy road driving, it is advisable to open the headlights in advance, so that the road potholes will see more clearly.
(3) night through the curved road, hump road and other visual blindness can not see each other, be sure to use the conversion of high beam, low beam method, do 1?2 times blinking, in order to remind the blind area of the people, car ready to avoid. (4) night driving in the other car occupying the road and not in accordance with the provisions of the change in the far and near the light, you can change the far and near the light, send a signal to prompt.
(5) night road in front of the bicycle, pedestrians more, a slow down slowly; Second, to increase the number of far and near light conversion, so that the bicycle, pedestrians will see more clearly. (6) In the night meeting, such as the other side of the car does not do low-light conversion, has been irradiated by the high light, the car should be immediately changed to the near light, not the two cars far light on the shooting.
In this case, change into the near light but will see clearly, each other on the shooting will be unfavorable to their own, it is easy to cause both sides of the dazzle and crash together. (7) In the night road overtaking, the use of alternating high and low beams to warn the car in front of the car, the car in front of the car is easier to perceive the actual distance between the two cars to be overtaken, but the number of conversions should not be more than two at most, and to grasp the distance between the two cars is more appropriate.
(8) In heavy rain and fog, it is advisable to convert the far light to near light in time, so that the road will be more clearly seen. At the same time, the fog lamps should also be turned on to prompt passing vehicles.
(9) in the dawn driving, turn off the headlights sooner rather than later. Because through a period of night driving, the eyes have a strong dark adaptability, dawn earlier off the headlights will not affect the observation, and will be on the road to see objects more clearly.
(10) daytime driving, pulling the headlights switch, both as a temporary borrowing each other "right of way" driving, requesting cooperation signals, but also as a way to prevent each other car penetration, occupying the prompt signal. (11) encountered in driving acquaintances driving a car to greet, usually in the two cars close to the sound of a siren, and during the day in the region prohibited from sounding the siren driving, can also be changed to flash the headlights to show greetings.
(12) in the daytime overtaking, encountering car noise or closed better and open the sound of small cars, can not hear the horn, the rear car can also be able to see the front car left mirror, pull the headlight switch, signaling tips. At this time, in the front car's left mirror, there will be a car after the headlights of the bright spot, can receive a better prompt effect.
(13) in the city during the day when driving on the streets prohibit honking, met with the left and right lanes of the car attempted to force the line into the car in front of the car (especially when the car is located in the side of the car's line of sight blindness), can also be the light of the headlights to the front of the car's tail, the use of reflective effect to be prompted. 7.
The use of fog lamps Fog lamps can help drivers in foggy driving to improve visibility, and can make the opposite side of the car in time to take measures to take, safe meeting. Therefore, when driving on a foggy day the driver must turn on the fog lights, can not be replaced by a wide light.
Note: non-foggy weather if you open the rear fog lights, it will affect the rear driver line of sight, not conducive to safety. .
3. What are the basics of lighting
Luminous flux: the radiant energy perceived by the human eye.
The sum of the product of the radiant energy of each band and the relative visibility of the band. The unit symbol is lm.
Illuminance: the luminous flux density to a surface, symbolized by lx. A 40W incandescent lamp luminous flux is about 340 lm; a 40W fluorescent lamp luminous flux is about 1700-1900 lm.
The basic requirements of the indoor lighting: 1, according to the general lighting and special circumstances to set up the two groups of programs. For example, the study with a small lamp and a larger brightness of the desk lamp.
2, set up a group of programs according to special circumstances: for example, the study only set up a large lamp. The first group of options above is a better choice.
First of all, according to different situations, choose a different illumination, is conducive to the protection of eyesight, to avoid long-term too strong or too weak light on the eyesight damage. On the other hand, it is conducive to saving electricity, thus saving money.
4. What is the feng shui feng shui of light
1, reading and working area to strengthen the lighting, while the sleeping bed to avoid direct lighting, so as not to be difficult to sleep.
2, to avoid the formation of shadowy areas, so do not use a single central light source, but a combination of multiple light sources. Floor lamps are one option, or more economical table lamps can also be used.
It is best to choose a table lamp with a curved handle in order to adjust the angle of the light source. 3, it is best to avoid the use of fluorescent lamps, because fluorescent lamps will make people easy to fatigue, distraction, should be replaced by soft light bulbs.
Also, it is best to paint the walls a light color to make the room brighter. 4, the light is Yang can be used to revitalize the Yin heavy area of the aura.
5, in the beam placed under the upward light of the standing lamp, can dissolve the bad luck. 6, the front door of the "Hall of Fame" area is the most important part of the feng shui of the house, the placement of street lamps can help gather gas.
7, not in the dark corner of the mirror placed in front of the lamps, easy to lead to the "ghost" phenomenon. 8, bedroom lighting should not be too bright, otherwise it will hinder sleep.
5. Seek common sense about lights, lighting
Lighting is the use of a variety of light sources to illuminate the workplace and living or individual object measures. The use of the sun and sky light is called "natural lighting"; the use of artificial light source is called "artificial lighting". The primary purpose of lighting is to create good visibility and a comfortable and pleasant environment. Interior design lighting is a variety of architectural environment of the illuminance, color temperature, color rendering index and other professional design. It is not only to meet the requirements of indoor "brightness", but also to play a role in the environment, atmosphere. Generally requested by the interior architects, electrical engineers for accounting, adjustment. At the same time, it also refers to the action of lighting or the state of being illuminated by the light.
In the movie shooting, the use of natural light or artificial light of an art. Involving the use of lighting equipment, light design, scene layout, light level, light ratio, shadow and light effect determination, lens lighting treatment, etc., is an indispensable means of creation of the photographer (see the art of film modeling, film lighting).
Lighting design should be human-centered, but must first consider the safety and practicality, as well as illumination requirements, installation methods, maintenance methods, and then finally combined with humanized creativity, a good lighting design, must have the above prerequisites, in the lamps and lanterns have been related to the relevant articles, lighting design can be referred to the Jurassic Lighting related literature.
Lighting is the use of artificial light or natural light to provide people with sufficient illumination (general lighting), or to provide good identification (road lighting, advertising signs, etc.), the emphasis of the characteristics (architectural lighting, accent lighting, etc.), or to create a comfortable light environment (residential lighting, etc.), to create a special atmosphere, etc. (commercial stage lighting), and for other special purposes (biochemical, medical, botanical cultivation, etc.) Means.
Lighting can be divided into: general lighting, zoning general lighting, local lighting and mixed lighting. The principle of its application should be consistent with the following provisions:
First, when it is not suitable to install local lighting or mixed lighting is not reasonable, it is appropriate to use general lighting;
Second, when a work area needs to be higher than the general lighting illumination can be used in the general illumination of the district;
Third, for the higher illumination requirements, the work of the location of the density of not too much, and the installation of a separate general illumination is unreasonable, it is appropriate to use mixed lighting;
Third, for the illumination requirements, work location is not dense, and separate general illumination unreasonable places. Place, it is appropriate to use mixed lighting;
Fourth, in a workplace should not be installed only local lighting.
6. Who can talk about the knowledge of the lights, that is, what kind of lights signal what they mean
Headlights divided into far and near the light, the vehicle is open when the lighting.
Small lights and turn signals are generally in the same position, small lights is the role of the visual width lights, that is, in the dusk or foggy days or at night when parking can be opened to show the width of the vehicle. Turn signal for steering use, located on both sides of the vehicle, divided into left and right before and after the two switches, that is, when the vehicle to turn to hit the turn signal in advance or overtaking to hit the left turn signal.
The front fog lights are usually turned on in foggy weather.
Rear taillights (rear wide lights) are located at the rear of the vehicle on both sides, with the small lights (front wide lights) the same reason for the same switch. The rear turn signals are the same as the front turn signals with the same switch.
The rear fog lamps are located below the vehicle's left rear taillight, and are usually turned on at night on the highway.
Brake lights and rear taillights open a lampshade, step on the brakes when the light, so that the rear vehicle knows that the car in front of the brake.
The license plate light is generally located above or next to the license plate, generally the same switch with the lights, for illumination of the license plate, so that the traffic police check the car at night to see the vehicle number plate.
7. Basic knowledge of stage lighting sound
I think for the sound, now we basically every household will have an impact, just there will be good and bad respectively, so how much do you know about the general knowledge of sound equipment! So how much do you know about the sound of stage lighting! Then I today for you to briefly introduce the basic knowledge about the sound and stage lighting common sense, I hope to be able to attract your attention.
1, when we watch the stage, we must pay attention to the stage colorful will show a lot of light, because it can first cause our visual sense, cause our visual sense of these light should be our life is often said to be visible light, they are red, orange, yellow, green, blue, blue and purple this 7 kinds of monochromatic light, but according to a large number of experiments to prove that we are also more sensitive to yellow and green light, therefore, we are in the stage lighting arrangement. We in the stage lighting arrangement, we must pay attention to the deployment of light, and then the deployment of the tube when we also pay attention to the brightness of the light and hair over the angle, so that people will not feel blinding and will also be with the ups and downs of the music to give people a kind of enjoyment of the United States, so the stage lighting is a sense of rhythm to give a person's sense of rhythmic visual impact on the sense of beauty. And we should know that different colors on the human psyche has a different *** effect, so most of us listen to the song, if the song is more melancholy and low key we will emotionally feel the stage lights emitted by the color is relatively cold, if the song is more high-pitched, then we will feel particularly excited, so it's hotter effect.
2, about the types and characteristics of stage lighting, generally speaking, we all stage use of incandescent, fluorescent neon laser lights and other lamps, these lamps and lanterns are manually controlled, some are controlled by mechanical control, but also by the control of the sound, as well as received computer control, some are still subject to the control of the program, and therefore will give a person feel the effect of the different, and the use of spotlights will make the localized lighting, so we will feel particularly excited. The use of spotlights will make the local lighting effect is better, with a high degree of directionality targeted, the stage screen if there is a more focused, generally use spotlights, if we want to spread the focus of the stage these times, we will use the backlight and floodlights, and we often see the highest and computerized these. The control of these lamps, we also have to be based on the form of the stage, so that a music to achieve a better effect.
3, about the stage sound, because the sound is subject to electrical signals reduced to sound preferences for this equipment, so we are in the selection of sound, there will be a big difference, the following types include anti-magnetic sound, full-band speakers, flat-panel sound, USB sound, these types of different effects, the sound on the stage with the sound to make sure to pay attention to a variety of sound characteristics of the placement! This will make the sound effect to achieve the best, the number of sound placement should be moderate, because the loudness control is more important, if our hour 500 hair too much words beyond the human strength of the adaptive range, then it will make people feel uncomfortable, as long as the stage of the music can not achieve the best results. On the stage of the basic knowledge of lighting and sound I will introduce here, if we are on campus or in other public **** occasions to hold a concert, we must grasp these basic common sense, otherwise it will not be 15 stage of the concert to achieve the best results, and some of them will also appear to be the phenomenon of the contrast, I hope to be able to help you.
