High school students with what kind of table lamp is better
High school students with what kind of table lamp is better, table lamps are divided into many kinds, which many kinds of student table lamps are also suitable for different ages. If you are a high school student, there are many places to pay attention to the choice of lamps, the following high school students with what kind of table lamp is better.
What kind of desk lamps for high school students is better1Choose a suitable, eye-care desk lamp should be considered from the following aspects: light source, color temperature, brightness, optical processing technology.
Light source: so far the light source on the market is roughly divided into four: incandescent lamps, energy-saving lamps, fluorescent lamps, LED lights.
Incandescent advantages: no strobe, high color rendering. Disadvantages: large heat generation. (Table lamps as close lighting, due to the relatively close to the head, continued use for a long time. When the use of incandescent lamps as a light source, because of its heat is too large, the most intuitive reaction is dry eyes, swelling of the mind)
Energy-saving lamps Advantages: more energy-saving, longer than the life of incandescent lamps. Disadvantages: unstable light source, high color temperature, easy to shake the eyes as close lighting
Fluorescent lamps (although some businesses claim that their desk lamps are three-color desk lamps, but essentially the use of phosphor as a light-emitting medium, three-color is only a gimmick business publicity, and three-color because of the use of phosphor color miscellaneous light is much poorer than the ordinary monochrome fluorescent lamps, it is not recommended to use)
The most intuitive reaction is that it is too much heat. )
LED lights: LED lights due to its long life, green, light and sunlight similar to the countries around the world to vigorously promote, some of the Europe and the United States has been fully popularized. Qualified LED light line pure, high color rendering index, long life, and because of the nature of its light-emitting diode, must be powered by DC to work, which essentially determines its radiation-free, strobe-free, is the true meaning of eye protection light source.
Color temperature: There are three main color temperatures in common use: around 3000K, 5000K, 6000K.
3000K color temperature is the most common representative of the incandescent lamp, the light is yellow, so people feel warmer, but visually feel the brightness is not enough, this type of color temperature is usually used to create an atmosphere, the room is used more, showing a warm feeling.
5000K or so color temperature, the color temperature of the sun around 9 o'clock in the morning, the light is yellowish, bright and does not feel harsh. With the appropriate brightness, the light will feel very comfortable.
6000K or so color temperature, the most common to energy-saving lamps, light pure white, visually feel very bright, if you use it in the desk lamp as a close range lighting, due to its pale light, so that people will feel visually shaky, but also feel very uncomfortable.
PS: There are now some LED desk lamps on the market called adjustable color temperature, and because the color temperature of the LED light source is designed to be fixed, so these desk lamps are two different colors of light source for different brightness ratio, in order to achieve the function of changing the color of the light, such desk lamps desk lamps in an accurate sense should be the dimming of the color desk lamps, not color temperature desk lamps, but also because of the light of its two colors Mixed, so that the light is not pure, the eyes will also cause some harm.
Brightness: The right brightness can make the light softer and more comfortable.
Brightness is too bright, we will feel blinding, brightness is too dark and make us difficult to see, so the right brightness is very necessary, but due to the sensitivity of each person for the brightness of the difference is very large, so ordinary lamps are very difficult to meet the needs of each person for the light of the personalized, and want to achieve the purpose of the real eye protection, the right brightness is very necessary, so the purchase of table lamps when the best to buy a dimmable table lamp. Dimmable table lamps. (Dimming lamps refers to the induction dimming, some graded dimming lamps and non-dimmable lamps essentially no difference, it is difficult to meet the personalized needs of each person, so it is also inappropriate)
Optical processing: Because the lamp light emitted by the light is mixed with stray light
The light emitted by the lamp is mixed with other light, and there may be a glare, so a reasonable optical processing technology becomes very necessary.
What kind of desk lamp is better for high school students2 First, what should I pay attention to when choosing a desk lamp? Desk lamp selection should pay attention to three aspects, one is the light source, the second is the color temperature, the third is the brightness; Light source, all the current light source, the LED light source is considered to be the closest to the natural light, and the color reproduction is good, long life, high luminous efficacy and so on, and the most direct is that we will watch the LED TV will be more than the ordinary TV feel comfortable, this point also explains the LED desk lamp will be more than ordinary desk lamp. LED table lamps will be more comfortable than ordinary table lamps. Color temperature, incandescent color temperature is about 3000K, fluorescent lamps are about 6000K, the color temperature of natural light at noon indoor is about 5000K, and the natural light is the best, so the color temperature of children's table lamps should be about 5000K. Brightness, too bright or too dark eyes will feel uncomfortable, so the right brightness is very important, and each person's sensitivity to light is not the same, so the ordinary lights on the market can not meet the needs of all people, at this time, dimmable table lamps become necessary.

I think that if you buy a desk lamp, first from the perspective of eye protection, which has two aspects: one is the individual reasonable eye use; the second is the use of light suitable for and reduce eyestrain. In the second aspect, there are suitable for the human eye light intensity (illuminance) and the nature of the light, that is, the color temperature of the light and whether the flicker. Only from the flickering aspect of the relationship, incandescent, high-frequency (no flicker), LED lights are all, but the latter two luminous efficiency. What are the benefits of led eye lamps? LED eye-care desk lamps are generally used in reading, writing, designing, reviewing, and other office or study lighting use places. For people who do desktop learning, to ensure a good visual environment in the work area, to improve the quality of learning and office, improve work efficiency, and protect the health of the body has great benefits. Only by fully recognizing the characteristics of lighting and selecting the right ` lamps and lanterns, we can make our learning and work become more relaxed and comfortable, healthier, more colorful life, work more enjoyable. In the use of LED desk lamps places, if the illumination and color rendering of the light is not enough, it will make the reader overuse of vision, resulting in eye fatigue, and the lighting light for a long time flicker or glare will bring serious harm to the human visual nervous system, so special attention should be paid to the quality of lighting. From the point of view of human lighting comfort, health and take into account the energy savings, LED eye lamps should have five conditions: 1, desktop lighting to have enough illumination At present, China's schools and office buildings and other lighting places commonly used lighting design standards were developed in the 80s, which the office, the study of the desktop Illumination standard is only 1/2 of the international standard, the international standard is 300-500 lux (lx), and our standard is about 150 lux. Illumination is too low or too high will make reading difficult, easy to cause reading fatigue, affecting reading and work efficiency. 2, the light should be stable If the light is bright enough, but in the non-stop "flashing", the light is not stable enough, we say it exists! "Strobe". When the strobe exceeds a certain range, it will produce visual fatigue. And long-term visual fatigue will cause damage to the human visual system. Especially in the increasing popularity of computers today, many people use computers under the light, usually the strobe of the inductively ballasted fluorescent lamps and the frame rate flicker of the fluorescent screen (50-100 times per second to change the screen) overlap, forming a light *** vibration, which is even more damaging to the human visual system. Prolonged reading or working in this lighting environment can damage the eyes and have uncomfortable symptoms such as eye swelling and headache, and usually can not find the cause. 3, the color rendering index is not less than 80 The color rendering index is the degree of light on the color reproduction - we call it color rendering. In the lower color rendering index of the light (generally 60-70 fluorescent lamps) to see things, the eyes of the color discrimination ability is low, easy to cause visual fatigue. Generally, the color rendering index of desk lamp lighting should not be less than 80. 4, no glare The human eye is affected by glare, it will feel the stimulation and oppression and the loss of bright and comfortable atmosphere, a little longer will produce mood boredom, anxiety and other emotions, the reading and work will have a serious adverse impact. 5, the use of green lighting products Promote the use of energy-saving light source has been China's energy-saving policy to promote green lighting is to refer to the environmentally friendly, so that the lighting products do not adversely affect the environment, and at the same time can reflect the modern civilization of the lighting culture. The core of green lighting is to choose efficient, energy-saving, environmentally friendly light sources, accessories and lamps. Only by fully conserving energy can we reduce the emissions of CO2, SO2 and NOx from power plants to the atmosphere, thereby reducing the greenhouse effect that causes global warming, reducing the production of acid rain, and avoiding respiratory and other diseases produced by the human body living in a certain concentration of SO2 and NOx air for a long time. This article describes the benefits of led eye protection desk lamps, but also describes the qualities that a qualified led eye protection desk lamp should have. If you are a student who likes to study at night, or an office worker who often works overtime at night, then buying a high-quality led eye lamp is a must.
