Q:LED lamp charging and then bad
Now small home appliance products, such as LED lamp manufacturer in order to save costs, the internal circuit is very simple, direct is the way of resistance capacitance charging circuit, and probably doesn't even have the battery charge over discharge protection, quality is not guaranteed.
Q:Why is the largest lamp radiation?
Traditional desk lamp because have ballast, and people generally, it's close by all said have radiation is larger. LED it has a blue light, the key is not to direct eye to light, had better choose the desk lamp of a chimney. Such as this.
Q:New LED lamp USES "magnetic -" the voice from time to tome, how to eliminate the noise?
Light impact is not big, but it is defective, shake the mostly transit, it is possible that production process problems. Can change, don't change as I said
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:LED the desk lamp that shield an eye to choose good warm light or white light is good?
All said no white or warm white light, how still stubbornly say which good? So you say like fluorescent lamp of white or yellow incandescent lamp? Want to that is that, it's all the same eyes, no better.
Q:I am doing an LED desk lamp,
Using PWM technology, you need to use single chip microcomputer output a certain duty cycle of square wave, the duty ratio, the greater the more bright. Also need to use sensors to collect light intensity, the establishment of a model, to achieve automatic brightness adjustment.
Q:The LED lamp how to realize the function of adjustable brightness and color temperature?
Simple dimming can be concatenated in the LED lamp bead loop resistance, change the current, can adjust the brightness, better with adjustable brightness of PWM pulse width adjustment, circuit is more complex. Color temperature seems to be no commonly, by LED lamp bead characteristics (fixed) materials and manufacturing has decided, unable to adjust.
Q:The voltage of the LED lamp is about how much
No, now the best solution is a string of ten. And then in parallel. Voltage is controlled in 32 v, with constant current source driver. Safety, high efficiency
Q:New LED small rechargeable lamps filled with electricity or running
First power consumption, basically see your battery is what material, have the ability to remember. If nickel-chromium batteries will be used up first, then charge, you can't have the to lithium ion.
Q:LED desk lamp and ordinary lamp which good?
13 w lamp, what LED? 5 w is enough! With LED benefits a lot! What no pollution, no flash! Wait a minute!
