[Disassembly] Several Philips LED light cups "surprise constantly"

Disassemble the LED light, there are several Philips light cups on hand. In fact, there are several versions. Of course, in addition to the difference in color temperature, there are two or three circuits and heat dissipation.

First look at the three different types of lights that I have on my hands.

This kind of heat dissipation is very domineering. Wow, I really like the shark tooth design. I changed it a bit.

Another kind of heat dissipation, this is more common, the number is more, and the heat dissipation of the tooth shape is still relatively small.

This kind of note, unlike the above two, is 5 pins. After research, it should be dimmable, but the dimming circuit should be used with the voltage regulator circuit at the back of the lamp cup.
