FAQ

LED what kinds of screw bulbs are there?
There are E14, E27, E40, B22, LED bulb, only these screwsThe most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.
Where can LED bulb be used?
LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection.
Secret LED bulb bubble price difference why so big?
Component material. Whenever cheap prices are shoddy, without exception
Seeking the production process of LED bulb... Thanks
10 points, Baidu wants to be a LED engineer. LZ is a real budget man
What's the reason for the LED bulb strobe?
8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.
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.
LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
How many seconds delay? It won't take so long. How many bulbs do you usually soak in 0.5 seconds? A squeaky noise is usually a transformer or inductance whistle, and at least it shows a poor manufacturing process.
Want to find common features, unified purchase accessories repair!
The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
