Q:How to maintenance of led desk lamp filled in no electricity
Possible battery charging circuit is broken, seeing you is what buck circuit, if it is a transformer or resistance and capacitance step-down circuit is relatively simple, maintenance is a electronic components, slightly understand electronic knowledge can repair myself. If it is switch power supply is trouble to repair, to professional maintenance technology to repair.
Q:Why is the largest lamp radiation?
The expert reminds: currently on the market is filled with all kinds of cheap inferior LED desk lamp. Is common medical test and optical test showed that the LED blue light damage, only through the blu-ray isolated from the desk lamp of the blue is the blue light lamp. When parents choose and buy the lamp don't blindly covet a low price.
Q:LED rechargeable lamps learning how many watts?
Generally 5-10 w. 1. LED desk lamp is with LED (Light Emitting Diode) the desk lamp of the light-emitting Diode as Light source, LED is a solid-state semiconductor devices, it can be directly put DianZhuan into Light. Is the third generation after the incandescent lamp, fluorescent lamp lighting technology, has the characteristics of energy saving, environmental protection, safe and reliable, solid-state lighting is favored by the industry in the next decade to replace traditional lighting appliance potential new light source, represents the future of lighting technology.
Q:LED small desk lamp, found that the charging indicator light is not bright, or bad?
You put the electric light, and then filling, can see light, not just can not charge the electricity, if can light is the light is broken, and there's some light charging is not bright, full of bright, look ok
Q:Children lamp good choice led lamp is better
Can, LED by natural white light bead (osram), tube made of three primary colors. Starting from protecting eyesight, try not to read for a long time, should have proper rest, look at the distance, eyes
Q:Led lamp is broken. Who knows what reason be? How to repair?
Lights all broken may be small, generally is constant current source power supply box, inside element inside a lot, no maintenance base best to replace the power supply box.

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.
