Occasionally, I removed a few 3W LED lights on one product. At first, I didn't look at it as a mountain product. The rear machine took a look at the famous Lumileds. I guess many people have never seen it sent to everyone. Look!
At first glance, it is very common, a bit like a domestic cottage product.

The triode, the full name should be a semiconductor triode, also known as a bipolar transistor, a crystal triode, is a semiconductor device that controls current. Its function is to amplify the weak signal into an electrical signal with a large amplitude value, and also as a non-contact switch.
Transistor is one of the basic components of semiconductors, with current amplification, is the core component of electronic circuits. The triode is made up of two closely spaced PN junctions on a semiconductor substrate. The two PN junctions divide the monolithic semiconductor into three parts, the middle part is the base area, and the two sides are the emitter area and the collector area, and the arrangement is PNP. And NPN two.
