- Q: Led desk lamp and common desk lamp which is good
- If the wavelength change, stimulate phosphor ability to drop, luminous efficiency will be lower. Manufacturers in order to pursue the brightness, usually to strengthen the blue LED light intensity, the eye if the long run, such a source to avoid eyes blue light damage. In addition, it is, the longer the LED light, the faster the phosphor decay of light source, the result will lead to the human eye contact blue wavelengths of light is more and more intense, so as to cause harm to the human eye
- Q: I'm doing a LED desk lamp, can be through the outside light intensity automatically adjust the brightness of LED, using PWM technology, how to do excuse me
- 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: 22 what is the power of the led lamp charging desk lamp v
- Do you want the output voltage or input What's going on?I hope you can help me.
- Q: How long will leds last?
- Absolute durable, more durable than bulb or tube had, but are you going to buy factory goods, don't look at somebody else's expensive, but it is good, no matter the luminance or life is good.
- 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: Of tubes is said to be good, and some say good leds, which is really good
- Incandescent lamp is red light, yellow light is refers to the 2700 k color temperature, most provinces to eyes, fluorescent tubes and LED light is dazzling.
- Q: LED the desk lamp that shield an eye the choose and buy, should consider what respect?
- Now is better the desk lamp that shield an eye to choose the low voltage dc power supply, safe, no electric shock hazard Cold light source options, select light source, high brightness, high luminous efficiency/low energy consumption, no ultraviolet and infrared radiation. Also need to consider the color rendering index of lamps, light color rendering index is 100, color rendering index of desk lamp, the more close to the sun color rendering index, adaptable people eyes, eyes, vision health. With and without glare is also an important standard, because dizzy light is one of the important reasons of causing visual fatigue, can choose light measurement, the desk lamp of surface light source, because traditional desk lamp can directly see light point, more dazzling, side light can't see the markers, the light is downy, uniform. Select the adjustable brightness or color temperature LED the lamp that shield an eye, because of different scenarios, different weather, the brightness of the light or there will be a certain color temperature, on-demand light distribution, science more eye. (I had to use of the lamp, can consider)
- Q: LED lamp circuit of current more conference appear what problem
- LED current assembly LED life expectancy, calorific value is big, long droop decay quickly makes the current big but light from the darkness, also is actually short service life. String or depending on the design of the circuit. The string of reasonable and important. LED type belongs to the current control device, it is recommended that the concatenated as much as possible, control current. But the list of much needed voltage too much is bad for safety. When the number of string reaches the corresponding voltage should be increased and accordingly. Such as lamp had better control transformer within the safety voltage is better, after 24 v, for example, the pressure drop of about 3 v LED, and the best in a 6-7 more appropriate, the branch with current constant flow control device for the LED work, the more number of lights, and the same number again with constant current control, this is more reasonable.
- Q: Desk lamp battery charging why not directly connected light emitting leds, but to a diode, the diode have what effect
- Charging desk lamp is two to 2 v battery combination section two is 4 v battery current also big white leds optimal voltage at about 3 v Scope of work of floating + - 10% plus pressure drop a diode is just 0.7 V power 4 V - 0.7 = 3.3 thus satisfy the white LED lamp working condition No diode LED will be hot Even burned
- Q: How many watts of led the desk lamp that shield an eye with good students
- LED lamp general 6/7 w is very bright, is too light is bad for your eyes.Have a personal 11 18 w
