Q:How to identify what the real eye lamp?
And people accidentally touch can also cause accidental burns, it is for people with a safe hidden trouble problems. While the LED lamp will not produce this kind of situation, Angle lights lamps are doing reliability test of time, five desk lamp work for two weeks in a row, the lamp body, the highest temperature is no more than 40 degrees, most Gao Wudu than the environment temperature, from this point of view, the LED desk lamp more security than the general desk lamp. x0d third, LED desk lamp spectrum is the most close to the sun, and every day we at least half of the time exposed to sunlight, the human eye to adapt to the sun is the most, so add a light source can be infinite close to the sun, so our eyes under the influence of light will be more less, the human eye would feel more comfortable. So as to achieve the purpose of the eye!
Q:The LED lamp electrostatic test pass the corrective actions
See which part of the circuit is broken? Such as the LED part or dimmer IC. So taking measures to more targeted.
Q:LED lamp wattage? How much is the smallest biggest respectively?
Leds can be according to the power consumption, is divided into different power range, general individual has 0.1, 0.3, 0.5, 1, 3, 5, 10, 20, 30, 50, 100 tile, etc.,, if see now use leds, there are a lot of LED, depends on the wattage, etc.
Q:The LED lamp can change the light bulb
LED desk lamp is small current is energy-saving lamp, lamp power current too big, want to use have to change very troublesome, some parts to replace. The LED desk lamp is to protect the eyes and the light bulb is 50 hz frequency of eye fatigue.
Q:Low voltage LED desk lamp belongs to the scope of 3 c certification
What is the low voltage LED lamps, whether with a charging device. If you are charging device, or take the adapter to connect power part is need to do
Q:Non rechargeable LED lamps have a stroboscopic?
Normal LED desk lamp not stroboscopic, this is decided by are rechargeable LED desk lamp power supply. 1, the common battery power, the power supply itself is no stroboscopic characteristics, driven by its leds stroboscopic may not happen. 2, use UBS power, UBS power is through the conversion of switch power supply dc voltage source, the voltage fluctuation is small, could not have caused the LED strobe. 3, using a dedicated dc power supply, its form has two kinds of current source and voltage source, are generally not switching power supply, stability is very good also, normally not stroboscopic. If it is found that the LED light stroboscopic explained the power supply circuit and fault, such as open circuit, LED lamp trouble light filtering capacitance.
Q:Led and energy-saving light which good? To solve the
Good long-term considerations must be LED, although the price is high, but long service life, power saving, and environmental protection, long term compared to the ordinary energy-saving lamps province, under the condition of equal brightness LED lamp power is only 1/3 of the ordinary energy-saving lamps. About life equal to 5 times the ordinary lamp.
Q:How to charge the LED lamp
When did you buy? If it is just bought, suggest you use first photoelectric charge again
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:Desk lamp battery charging why not directly connected light emitting LED lights
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
