- Q: How to distinguish whether the led lamps and lanterns glare, is there a standard?
- Glare can be divided into disability glare and arrow glare. Who reduce eye glare called a disability glare, it will be Reduce the visibility of the visual object, but not necessarily produce uncomfortable feelings; Who make the person produces the feeling of displeasure glare is called no Comfortable and glare. Cause glare of led lamps and lanterns has the following four major factors. (1) the light source brightness factor: the higher brightness, glare, the more significant. (2) light source location factor: the closer it gets to the line of sight, glare, the more significant. (3) the light source appearance size and number of factors: the apparent area, the greater the number of light sources, the more the glare, the more significant. (4) the surrounding environmental factors: environment brightness is dark, eyes adapt to lower brightness, glare also becomes more significant. Dazzling light not light, but for the concept of lamps and lanterns. Leds - t8 fluorescent lamp has been rise, are alternative Fluorescent lamp market, due to the lamps and lanterns is ready, can't change, leds - t8 fluorescent lamp needs to ordinary fluorescent effect Fruit near, thus formed the concept of glare. Anti glare products, need to consider the brightness of the led, led between the row Cloth, spacing, the led itself to the distance of the optical cover, the shape of the optical cover, light transmittance, etc., rather than simple Shell or configuration problem.
- Q: How to repair the led rechargeable small desk lamp
- If the part is not bright, check if not bright LED's virtual welding or burning.
- Q: General how long LED desk lamp charging full of learning
- Additional learning had better not use the led desk lamp is best to use incandescent lamp of desk lamp, led lighting is bad for your eyesight.
- Q: Pupils to do homework with good desk lamp is yellow light or white light is good
- Do your homework with white light lamp, room lamp with yellow light, this is the most close to natural light, best to protect the child's eyes
- Q: Low voltage LED desk lamp belongs to the scope of 3 c certification
- See were independent of a body or power supply Independence is the power to do 3 c lamp don't have to do
- Q: The principle of LED the desk lamp that shield an eye
- The LED similar principle. But the difference is that the LED is not by the electrons within the atoms jump to glow, but by the voltage on the LED on both ends of the PN junction, the PN junction itself form a level (in fact, is a series of energy levels), and then the electrons jump on this level and photon to glow. New LED display units are low power consumption, high brightness, long life, the advantages of small size, this article from the beginning of the LED display a brief history of the development of, surface-mount LED, automobile application is discussed and the development trend of LED lighting, LED to the Chinese engineers engaged in the development of display device has a certain reference value. Global the first commercial light emitting diode (LED) is made with germanium materials in 1965, its unit price is $45. In 1968, the LED research and development has made breakthrough progress, using nitrogen doping process to make GaAsP device efficiency reached 1 lumens/watt, and can emit red light, orange light and yellow light. To 1971, the industry and introduced with the same efficiency GaP green bare chip LED. Beginning in 1972 with a small amount of LED display for clock and calculator. The world's first using LED watch was initially sold in expensive jewelry store, it will cost up to $2100. Almost at the same time, HP and Texas instruments have also launched calculator with seven red LED display. In the 1970 s, due to the LED devices in the home and office equipment in a large number of applications, LED prices plummeting. In fact, the LED is the era's main text display and digital technology. However, in many commercial equipment, LED display also gradually by the fierce competition from other display technologies, such as LCD, plasma and vacuum fluorescent display.
- Q: The LED lamp is bad for your eyesight?
- I don't know how you this table lamp LED performance, but the average white LED light slants cold, as compared to that of the object under the LE in natural light color nature is soft, so as a desk lamp may not good for your eyesight. But replace other USES energy-saving lamp is very good at home
- Q: The LED current problem? LED lamp current problem? Said wanted to plan to buy USB LED lamp to use 5 v voltage current 190 ma computer USB interface as current 500 adapter up to 1 a pick 1 a current
- USB interface receive computer desk lamp, computer burden is heavy, easy to addled computer. Besides, desk lamp, desk lamp, 1 a current lamp current 190 ma, bad, or move a few desk lamp table lamp lights die.
- Q: When did you buy? If it is just bought, suggest you use first photoelectric charge again
- ?the progress of the halogen lamp is incandescent lamp, full of halogen gas in vacuum bubble has realized the halogen tungsten filament with gas circulation and greatly prolong the service life of the filament, perfect inherited the color rendering of the incandescent light bulb 2, energy-saving lamps, CFL (compact fluorescent lamps, the actual domestic called the lamp energy-saving lamps have a little not science...). CFL is a great invention, the field of electric light source characteristics can be made into any color temperature and high color rendering, due to the effect of glow of the phosphor powder, stroboscopic can ignore (low temperature is a problem). Advantage is high luminous efficiency, such as 11 w CFLS can completely replace 60 w incandescent lamp, and use tricolor phosphors CFLS can reach more than 80 color rendering, some high-end products can reach more than 90 The disadvantage is that the fluorescent tube is filled with mercury vapour, how to environmental protection is a big problem in manufacturing and recycling, partly responsible manufacturer in tube using mercury pills (haha, suspected of advertising), partly solved this problem... P. : energy-efficient light bulbs are more likely to buy on the market at present stage is cost-effective light source
- Q: Desk lamp good still tube of good to buy LED strips? Search light tube usually can use a few years need to change?
- Good light source directivity, on-demand lighting, as an emergency lamp is better. 2, small volume, the LED is basically a small chip is encapsulated in epoxy resin, and so it is very small, very light. 3, intensity of illumination is enough, meet the demand of your general illumination.
