Q:General led desk lamp how much a led lamp is usually how many watts
Also suggested that the lamp choose warm white color temperature (3000 k), or natural white color temperature (4000 k), light color not only warm but not dazzling, long time reading or writing homework eyes not easy fatigue!
Q:Household led lights all of a sudden not bright? What's the matter?
If it is suddenly not very bright, usually because of its heart - LED drive power quality problems, the result of current is not enough. You can open it and have a look at the LED string, and power, to find a professional power supply company with power supply, diy connected the input and output line. If the trouble is returned to the manufacturer maintenance, this problem should be something for manufacturers. If it is used with the not so bright, like how did not suddenly don't bright, quality problem is LED lamp bead, light failure is too big. If a lamp is on there are a lot of small lights bead is unlikely this case maintenance, cost and the cost is too big, can only be changed directly. If it is only a high-power lamp bead and COB encapsulation of LED, don't bother you also can buy back to transfer the lamp bead.
Q:Led lights can use how long
10000 hours continuous working time, I have a friend in a lighting store, called the zhongshan/lighting, want to buy, you can consult him oh
Q:How to repair the led rechargeable small desk lamp
If the part is not bright, check if not bright LED's virtual welding or burning.
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:Buy the LED desk lamp, what should be pay attention to
Light source is the first priority, and desk lamp selection at this stage mainly incandescent lamp, fluorescent tube, LED, LED due to energy conservation and environmental protection, has become the desk lamp that shield an eye light source of choice.
Q:Are LED lights compared to dc lights?
Basically agree with net friend in front of the answer. The desk lamp of ordinary incandescent light bulbs with energy-saving lamps, bulbs and tubes in the current is an alternating current. Incandescent lamp current is ac mains, 50 hz, on and off the 100 times per second. Filament is high temperature heating, heat capacity to a certain extent, to cool and hot, stroboscopic was not obvious, but low light efficiency, energy saving. Energy-saving lamps, is the mains ac rectifier dc, again for the high frequency inverter (several thousand Hz) communication, energy saving, stroboscopic is not obvious, not like a normal fluorescent lamp. LED desk lamp, the energy conservation, but see, on the market at present basically is a built-in battery, use mains charging can't use the lamp, can light up from the mains before, often charging more than 6 hours, often should charge, so if used in a short time is can, such as to use for light continuously over a long period of time, is not convenient. LED flashlight, with short time, it is very good. If there is no battery, do not need to charge, it is more convenient. Above for your reference.
Q:Led lamp generally not transformer, why also said some led desk lamp radiation levels
There will be no frequency transformers high-frequency transformer (a lot of switch power supply are to be used), and high frequency transformer has radiation. If there is a low frequency transformer (it does not need to high-frequency transformer) but not excessive radiation
Q:The maintenance of the charging table lamp
Household appliances maintenance led rechargeable lamps? Many users haven't noticed that some users will be LED rechargeable lamp is like electricity used up until then recharging it when you are going to use it. LED rechargeable lamp light life is compared commonly, if it is not because the excess voltage or short circuit, usually don't burn out.
Q:Led energy-saving lamps are easy to break
Don't usually, LED lights so far is one of the longest service life, and environmental protection and energy saving, good friends said out of the blue, to see
