Q:Detailed description of LED bulb lamp
Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes
Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
Q:Is it possible to manually weld LED bulb bulbs?
This is what you do very mature products, the most simple aging, is like this
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
With a high quality LED light, 6W will be enough;High brightness compared to incandescent lamp, more energy saving.
Q:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
You should say that the bulb of the bulb, usually PC material.
Q:What's the reason why LED bulb gets a lot of heat?
If the radiator has a large radiating area, the temperature is low
Q:What's the cause of the noise during the aging of LED bulb bulbs?
Either AC or DC LED lighting there will be a power module, a small hidden in the lamp body, the daily working state can produce high temperature, if the AC power supply temperature will be higher, because the lamp body appears to flicker, high temperature and long time will lead to the power supply module parts welding, weld or aging, so a lot of alternating current LED lighting the metal shell, to facilitate heat dissipation, the DC power supply is adopted to eliminate the flicker, reduces the electrical power, so the DC temperature should be low.
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: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!
The milk white paint can't see light, but the transmittance is only eighty percent a few. At present, the market has not seen in line with the economic benefits of such LED ball bubble glass cover, can reach ninety percent transmittance. If any brother finds it, please let us know. We also want it very much. Oh, thank you.
Q:What are the characteristics of LED bulb?
Less power consumption, a 5 Watt LED bulb, equivalent to 40 watts of ordinary incandescent.
