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.
LED thread specifications for bulb bulbs?
Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!
What brand of LED bulb is good in quality?
See shape. Incandescent bulbs are usually pear shaped, so the bulb should be pear shaped. That's easy to do. But incandescent lamps are all glass products, and because LED requires heat radiation, aluminum alloys are usually used as housings, because of their low cost, easy processing, and good thermal conductivity. The size of the aluminum shell determines the heat dissipation and also determines the life span.
What are the characteristics of LED bulb?
Energy saving research data show that, as LED is a cold light source, semiconductor lighting itself has no pollution to the environment, and compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of ordinary incandescent lamp and 1/2 of fluorescent lamp tube. If we replace 50% of our traditional lighting with LED at present, the amount of electricity we save every year will be equivalent to the sum of the total power generated by the Three Gorges power station, and the energy saving benefits will be considerable. LED, the lightning man at home, is pretty good
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!
Can reach 90% of the light, can not see the inside of the lamp
Will the power of the LED bulb grow longer and longer? Why?
In general, LED energy-saving lamps (including LED bulb bulbs) use a constant current drive that does not change the magnitude of the current with time or temperature, so it does not become more powerful as it grows for longer periods of time.On the other hand, if because of long time use leads to LED lamp temperature rise, according to the electrical properties of semiconductor, the PN junction voltage will also decreases with increasing temperature. Then, when the current is constant, a drop in the voltage drop means a decrease in power consumption, although the reduction is very small.
How to identify Ic constant current LED bulb?
The general user how to judge whether the bulb with constant current IC power supply, the general bulb is divided into three kinds, one is the RC driven RC drives are the most simple, because the cost is very low power small bulb and lamp using the scheme of small power LED bulb is often driven by RC, RC driving disadvantage is LED current with voltage fluctuation is changed, the brightness will change, so the resistance capacitance in the price is cheaper and less demanding bulb drive only, one with the IC LED driver, this there is also a constant current power supply, but the precision of constant current IC is not high, this power can only be used in the 220V voltage, the voltage fluctuation of relatively large area will affect the brightness of the LED lamp, and the stability of the power supply is relatively poor, life is better than Relatively short, easy to issue, this power supply is only a three - stage tube and two regulators circuit very...
LED bulb w can replace 40W incandescent lamp
D lamp lumen value is ordinary incandescent lamp about 3 times, but LED ball bubble mask transmittance should be based on material, can use 10W or so LED acrylic mask ball bubble instead. Because I received a similar customer complaint, 7W's LED light bulb was replaced with an 20W energy-saving lamp, which was not bright enough.
