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:What's the reason for the LED bulb strobe?
In addition, electromagnetic interference (EMI) filters are also required, even in LED drive applications that provide excellent power factor correction and support TRIAC dimming. The transient current caused by the TRIAC step (step) will excite the natural resonance of the inductance and capacitance in the EMI filter.
Q:What brand of LED bulb is good in quality?
What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.
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 heat sink temperature and the temperature of the radiator is not the same, the heat sink through thermal grease or other heat conducting medium to heat to the radiator, the temperature will not coincide. And the temperature inside and outside the radiator is also different.
Q:What are the driving IC used in LED bulb?
MT7930, LM3445MM do bulb bulb, the effect is also ok.
Q:What are the types of LED bulb?
According to the interface, the LED bulb has GU10, E14, E27, E40 and so on.
