- Q: LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
- Energy-saving lamps, color rendering index above 80, it has a variety of color temperature. Read a book, I suggest to use 4000 k; High color temperature advantageous to concentrate, but Dazzling; Low colour temperature of concentrate. When reading a book, lamp writes a 1.5 meters, 300-350 lux. So-called energy-saving lamps, is high frequency, otherwise, it is not energy-saving lamps.
- Q: Led the desk lamp that shield an eye how to choose?
- No stroboscopic, this is the most critical. Color rendering index above 80 (the higher the better).I hope you can help me
- Q: Amount for the LED - 666 desk lamp can use charging 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 protection is good, 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: I want to ask to buy what kind of bulb to eyes good, leds? How many watts
- 220 v to 12 v may not use resistor step-down, so efficiency is very low and the resistance of consumed power is very big (18 times reached the bulb power), the original circuit could be a 220 v variable or a 12 v transformer AC - DC devices.
- Q: How many good study led desk lamp
- What do you mean how many degrees? Power? Brightness? Intensity of illumination? The temperature?With 3-5 w power leds.
- Q: LED lamp stroboscopic serious, can you tell me the reason?
- Is zero, because ac 100 times per second of voltage is zero, if simply step-down rectifier circuit, or filter capacitance is too small, through the LED current is 100 times per second interrupt, LED is a semiconductor light emitting, reach nanosecond, response time and tungsten by electric heating filament reach the state of incandescent light emitting, filament cooling speed is about tens of milliseconds, you can turn on the LED desk lamp to see the inside of the circuit.
- Q: LED rechargeable desk lamp the internal rechargeable battery, charging voltage is how old?
- Now that can tear down, can directly measure the voltage across the battery is generally a little more than 3 V, with USB 5 V charging slightly larger, it is best to 4 V or 4.2 V of mobile phone chargers.
- Q: Long card LED charging small desk lamp
- Use desk lamp of 5 hours a day, a month how to use electricity. This kind of LED desk lamp is very energy. If you are only used for lighting, can answer 0 degrees, almost no electricity, electricity meters are invisible. If you want to study how much degree, the za to calculate. 12 lamp holder is 12 leds, each press 3 v, 25 ma calculation, power P = 12 * 3 * 25 = 900 mw = 0.9 W, before considering other loss, even if the power is 1 W. 1000 watts of electrical appliances use 1 hour to 1 KWH 1 KWH, the desk lamp of 1 watt 1 months use 150 hours is 0.15 KWH. So for the average person can answer 0 degrees. Do you have any questions? Can you give me a message!
- Q: Led energy-saving lamps are easy to break
- If there under normal circumstances, the rated voltage of electric work flow, calculated according to 5% of 10000 hours of light failure, can be used more than 60000 hours, it refers to the undead lamp (not bad not only). If it is used in the lamp above, theory can be used on more than 100000 hours, up to 20 years, but if it is used as a light source (such as LED bulbs lighting equipment), the life is small, poor, 60000 hours are very long. Is about seven years, at that time although it can shine, but the light is very weak (relatively), we say it's broken, just light has weakened, but also can bright). This is to make the LED material, generally good LED by copper plating silver bracket, good light emitting chip, with high purity gold welding, good sealing rubber seal, if it is a white LED phosphors also requires good quality, any link problems will affect the quality of leds. Of course, affect the price of it. I hope it can help you O (studying studying) O ~
- Q: LED small desk lamp, found that the charging indicator light is not bright, or bad?
- Since it is new, then to find businesses, can ask how to use correctly.
