Q:Who knows where the broken LED bulb is?
The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
Q:What are the driving IC used in LED bulb?
Commonly used LED driver is based on the number of different W set, and now out of the drive program are quite a lot, according to customer requirements will also limit the number of different drivers IC.
Q:Can the bulb's true life reach 30000~50000 by LED?
The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.
Q:LED bulb with what type of LED beads?
Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier
Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
The meter usually doesn't turn because the current is too small to drive the meter (Mechanical), of course, the electronic meter also depends on the sensitivity. I don't think so. At least I used to do LED (light power about 0.5W it) is equivalent to 3W incandescent lamp brightness around. The meter does not rotate when it is shining normally.
Q:What's the cause of the noise during the aging of LED bulb bulbs?
The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.
Q:What does "A19" mean in LED A19 bulb?
A stands for bubble type, A hemisphere bubble19 the numbers in the back indicate the size of the bulb (mm in diameter)On the market LED bulb generally has: hemisphere bubble lamp, A15, A17, A50, A60Global bubble G45, G55, G80, G120 and so on
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
It's best to use heat conductive glue, such as ST922.
Q:Are there any differences between negative ion bulb and LED bulb?
Negative ions should belong to traditional lighting technology, LED is the latest lighting technology
Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
A sense of self is the following 1. package production process of wire bonding or partial welding weld. Whether the station is too large.2. through the current impact blanking line3. package factory using gold thread may be too fine
