FAQ

How did the trademark on the LED bulb go up?
And the use of silk screen or pad printing, this is the need for the corresponding ink, this solution with a dedicated solution can be dissolved, and also have some prominent hand touch.
What brand of LED bulb is good in quality?
What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.
LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
Speaking of attention should be to see if the light is even, PC material there are no scratches, spots and the like. It is difficult to test the proportion of raw materials used in PC materials, which is related to the aging time of PC materials.In addition, we should pay attention to anti-static.
Are there any differences between negative ion bulb and LED bulb?
LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.
LED how does the bulb return electricity?
A 0 ohm resistor with a large point on the negative electrode
How to choose the bulb power?
Obviously, the designer doesn't want the ball lights to work at rated current, but there is a margin, so the light bulb will work more reliably. Because of the constant current source, current of each lamp is not 30mA, but 330mA/13=25mA, of course, the brightness of the lights will be smaller.
How to identify Ic constant current LED bulb?
Look at the power supply, there are a few simple electronic and capacitive circuit board, it is not constant flow, cross flow is larger, so understand? Cross flow IC, that is, the meaning of intelligent voltage regulator, so that the LED is not easy, bad capacitor driven LED is relatively easy to damage, easily breakdown, and power consumption than the cross flow
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.
