- Q:LED the desk lamp that shield an eye the choose and buy, should consider what respect?
- Mainly has three aspects, 1 eligible product safety certification mark, confirm will not leakage, fire, scald risk factors such as user. 2 should have LED the desk lamp that shield an eye anti-glare light shade design, because LED is point-blank light, let the glare stimulate an eye for a long time can cause eye diseases, and even lead to amblyopia. 3 products must have a switch power drive leds, because there is no switch power drive LED desk lamp is used resistance capacity step-down power supply, easy to leakage, and we have 100 hz frequency flash light, no eye.
- Q:LED rechargeable lamp, can you tell me how long does it take to charge for the first time?
- If need to replace the light source (light pipe), be sure to refer to LED lamp assembly for the specified parameters of the charging, and don't change the structure. LED rechargeable lamps surrounding not moisture, dust and impurities, such as have found that clean up in time. Try not to over and over again when applying the LED lamps and lanterns of switches, it can greatly shorten the service life of LED lamp. LED lamp battery charging, if need to replace please select qualified products. Charging in LED desk lamp of power recharged when finished quickly, do not run out of electricity, and then filling, please stay in xiao yu battery recharging. If long time don't have to, but after a period of time the charging time, on the ground of deposit must be put in wet places.
- Q:LED the desk lamp that shield an eye to choose good warm light or white light is good?
- There is no white or warm white light, white light (more than 5000 k) bright point, feel good, as the object dyeing, less suitable for things looked fine, warm Bai Guangguang color yellow (below 3500 k), similar to the incandescent light, give a person with sweet feeling, suitable for one set his mind at to do something, but there are certain dyeing effect, also need not too extreme, actually can buy demitint between 4000-4500 k, with only a little yellow not had to take care of?
- Q:How many volts 4 w power led desk lamp
- Depends on what kind of, have 220 v, also has a charging V6, 12 v.
- Q:LED lamp, lens type and light type which good,
- If it is put on the edge of the desk lamp of the head of a bed or lens would be better, but before problem lens design is reasonable, no spot. Planar light light is scattered, suit to put on the desk, the hope can help you. You have to actually desk lamp is the key to no stroboscopic, this to the injured eye
- Q:Home to buy led desk lamp is broken? Can someone fix it?
- Led lamp production line is simpler, less complicated, general physics students will know their internal circuit structure, can also according to their own learning physical knowledge for repair, is a master of his own academic degree. If not, it may as well borrow coup. Led desk lamp is broken do next the third case is the light switch to normal, the general desk lamp can have between dark and light switch, if so, could be the governor, the interface carefully check, is there any loose or not, whether the governor is out of order, if the governor bad needs to be replaced, just stepping up strong interface
- Q:How many good study led desk lamp
- Last year I bought her son a 7-day's, now take down the feeling is very good
- Q:How about the LED the lamp that shield an eye, ok
- Of course there are good there, than fluorescent lamp is the biggest advantage of no stroboscopic. Buy should pay attention to look at the LED parameters: the first is the color rendering index Ra is more than 85, reduction of color ability. A second look at the desktop illumination, 500-800 Lux, don't be too bright, easy to produce visual fatigue. Third simulation under the child's reading position look have uncomfortable glare. About 4 color WenXuan 4000 k. I hope it can help you!
- 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 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
- Power supply voltage will not have an impact on power electronics, electrical appliances it needed current from power supply only, will not change because of the size of the power supply current.
