Q:Detailed description of LED bulb lamp: A bulb can be said to be the highest cost of the driver, not the driver, light is not bright. And for the quality of a ball bubble

Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb: The light produced by the three is different. From the lighting point of view, incandescent light can generally emit yellow light, and energy-saving lamps can not only send yellow light, but also white light, etc., and LED lights can be issued according to the needs of a variety of light, decorative lighting is very good.

Q:LED can the bulb be used in the bathroom?: Ordinary bulbs can be used in the bathroom, the bath water, protection grade ordinary bulb is not high, it is easy to make when water vapor lamps or rust element short circuit failure and cause some accidents. The bathroom is suggested by the power supply lamp, lamp waterproof plate etc..

Q:What brand of LED bulb is good in quality?: Look at the bulb of the bulb. The so-called bubble shell refers to the transparent glass shell in front. In incandescent lamps, all are made of glass. But in LED bulbs, though they can be made of glass, they rarely do.. Because the LED bulb weight than incandescent lamp 5 times or more, if made of glass, fell on the ground, it broke the possibility of large. As a result, more LED bulbs are made of plastic to prevent them from breaking. And the LED bulb went out because the heat from the radiator, so the bulb Everbright is visible light, infrared heating has little, so the use of plastic to make foam shell will not damage due to heat.

Q:What are the requirements of the LED series inspection specification for bulb bulbs?: The temperature rise of the finished lamp is not more than 120K. The temperature rise is equivalent to the maximum value of 60W incandescent lamp.

Q:What is the AC voltage of the LED bulb?: The conventional way to make multiple voltages is the 90V-240V ~50/60HZ 12V

Q:Led the bulb is flashing. What's wrong with it? How do you fix it?: There may be no aging, or there may be a power problem.

Q:LED how does the bulb return electricity?: maybe because Make the question clearWhat is the return current?

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 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.
