Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
There are several good LED ball bubble, which with aluminum cooling. Relatively new appearance.
Q: What's the reason why LED bulb gets a lot of heat?
LED light is a large amount of heat, more than 70% are calories. Different manufacturers are not very different
Q: Ordinary lamp LED bulb can?
Absolutely, without any effect. It can be directly across to look at the opening of several inches.
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: What are the characteristics of LED bulb?
Less power consumption, a 5 Watt LED bulb, equivalent to 40 watts of ordinary incandescent.
Q: Is it possible to manually weld LED bulb bulbs?
You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
Q: Led what's the flash of the bulb?
The internal drive of a cheap LED bulb is generally a resistance drop, and voltage fluctuations can occur in a flash. So all 100 of you are a flash.
Q: Detailed description of LED bulb lamp
A bulb is composed of seven parts, which are at the top of the glass cover is stuck on the base, the base will be above the hole, the base is connected with the heat conducting seat, heat conduction seat is connected with the radiator, connected with the lamp holder is the driving power, light is lamp.
Q: Want to find common features, unified purchase accessories repair!
The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.
Q: How did the trademark on the LED bulb go up?
Laser printing equipment is generally printed up, so that the ridge up color is not so deep, but also can not wipe off
