Q:LED rechargeable lamps didn't work for too long, the result can't shine! How to do?
Last time I also bought a rechargeable table lamp, I open on see, the result is the old NOKIA mobile phone batteries, tying my gas. You want to change the battery, to see your LED to a lot of voltage, current.
Q:Hello, I would like to ask you, if the desk lamp of household how much leds W?
LED desk lamp, sure enough, under 3 w is divided into warm light color temperature below 4500, more than 5500-6000600 is white light don't choose the color is not straight slant blue, warm red light is yellow, like the light bulb.
Q:The LED rechargeable lamps can charge while lighting? The reason?
Desk lamp is not poor, not because of burn out, because the light and a battery, so the voltage may be no more than the battery voltage
Q:LED lamp is broken, put it down, things do
Using the multimeter, diode first gear test lamp bead is damaged. Then find a chip, CL BP OB or PI, NXP driver chip both at home and abroad, and design a constant current drive power supply. Of course also need to look at your desk lamp lights, string and how. General desk lamp is the output of 0.3-0.35 - A, your driver can be designed so that the output current.
Q:How many watts of LED3 is equal to the ordinary energy-saving lamps
3 w leds is equivalent to 3 w of energy-saving lamps, not so simple than power depends on photosynthetic efficiency, luminous flux and color rendering, the quality of the different products are not the same as the 4 w energy-saving lamps can replace 20 w energy-saving lamps, good product can substitute for 35 w halogen lamp cup LED is also in the same way, the 3 w can also reached the standard of 15 w incandescent lamp, lighting is not suitable for lighting
Q:What LED lights so easy bad ah?
Main is you buy LED light quality is bad Should be made in zhongshan bargains Advice if household use bought some LED lights such as TCL mitsuo leishi
Q:LED the desk lamp that shield an eye the choose and buy, should consider what respect?
Brightness, brightness is too light or too dark can cause eye fatigue, so appropriate brightness is very necessary, we suggest electrodeless lamp dimming
Q:Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
This seems not, but can be modified, specific how to operate, can go to the shenzhen LED lighting look at technical articles on net
Q:Desk lamp with led bulbs or incandescent lamps good
LED lights: high light efficiency (energy saving), dc drive, no stroboscopic, blue light composition, rich color temperature, color rendering index relative incandescent bulbs will be lower
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.
