< p > high quality led light color line is the same, not be light yellow or other color.
If you don't know how to distinguish, here can say a small method, only the some lights lit, watch them change the color of the light can get the answer.
Due to the high brightness led linear light
, two kinds of brand of the same type lamp, under the same condition, with his eyes look straight comparison method of observation, is difficult to judge the brightness of high and low, at the same time it is easy to damage eyes vision.
Usually we recommend to cover the light source with a piece of white paper, through the white light attenuation, compare again, so it is easier to see the brightness of the light difference, the higher the brightness of the better.
< / p > < p > < / p > < p > the led lights need to be protected against static electricity lines: because leds are static sensitive components, if over the line maintenance of led lamp without good anti-static measures, will burn out the led, wasteful.
Here the need to pay attention to is the iron antistatic soldering pen is used, and maintenance personnel do anti-static measures (
Such as wear electrostatic ring and anti-static gloves, etc. )
< / p > < p > < / p > < p > led light is not on line, please check whether the circuit is connected, is bad contact, whether article lamp meet the plus or minus.
Article lamp brightness obviously on the low side, please check whether the power rating is less than the lamp power, or wires are carefully, lead to connect wires consumed power is too large.
Article lamp before than after please check whether the series length is more than the led line light manufacturer standard.
< / p > < p > < / p > < p > led lamp cannot be sustained high temperature lines: two important component part of led line light led and FPC, led line lights can't be sustained high temperature resistant products.
FPC if continued high temperature or is more than the temperature, makes the FPC cladding foaming, led linear light scrap directly.
At the same time, the led can't continuous high temperature tolerance, under high temperature and time is long, the led line wick will be high temperature burn out.
Therefore, maintenance of led lights with the soldering iron to be adopted will use the solder iron temperature control, the temperature limit in a range, literally change and set is prohibited.
In addition, even so, still need to pay attention to in maintenance iron don't stay in led light foot line for more than 10 seconds, if more than this time, it is likely to burn out the led chip line lamp.
< / p > < p > < / p > < p > circuit board as an important part of the led line lamp, led linear light of PCB requirements: 1: led circuit board, as a carrier of the light source directly affects the life and failure rate of lamps and lanterns.
Led lighting products, all electronic circuit on PCB, it material and processing technology of directly affect the quality of the product and life.
Circuit board material basically has: aluminum plate, glass fiber, half a glass fiber, cardboard, etc.
Led lighting products, standard material should be followed: aluminum plate, the glass fiber board, if use half a glass fiber or cardboard single panel later welding quality and moistureproof, anti-aging ability and electrical will be compromised.

Getting doesn't have to be expensive, time-consuming, or difficult. It all comes down to the right method and a led recessed panel linear led light fixture in place.
Exceed customers' expectations in the procedures of manufacturing led panel ceiling lights.
Dolight Optoelectronics Technology Co.,Ltd. is an expert in manufacturing a wide range of . We also have high quality led panel light distributor and many others. Visit to know more.
The key to led rgb panel is understanding where there is a problem or need in certain markets and knowing how to solve it.
