Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate

The standard is the body temperature of the LED lamp. With a multimeter probe is placed in the LED lamp bulb angle can be measured temperature. Generally -20~80 degrees centigrade

Q:Where can LED bulb be used?

Led bulb is now commonly used in civil products, is the most is a spherical bulb

Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!

See brightness, whether the luminous uniformity, the back of the heat is good?

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 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:How does the LED bulb go with the power?

voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,

Q:Is it possible to manually weld LED bulb bulbs?

As long as the welding technology clearance is possible or OK

Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!

Sandblasting can be transparent, light is not dazzling,But will still see the light...

Q:How to choose the bulb power?

If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.

Q:What's the reason why LED bulb gets a lot of heat?

If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long
