The basic structure of LED lights is a chip of electroluminescent semiconductor material, cured with silver glue or white glue to the bracket, then connected to the chip and the circuit board with silver or gold wires, and then surrounded by epoxy resin sealing, play a role in the protection of the internal core wires, and finally install the shell, so the LED lights have a good anti-vibration performance. The field of application involves cell phones, desk lamps, home appliances, and other daily appliances and machinery production.
There are two types of light engines in the market now, one is an electrolytically capacitorless light engine with high PF but serious flickering, and the other is an electrolytically capacitor light engine with no flickering but low PF. So which light engine is better?
LED light engine (light engine) refers to the overall combination of LED package (component) or LED array (module), LED driver, and other brightness, thermal, mechanical, and electrical components. The LED light source and LED driver power combined into a module can be called a light engine. If the LED is made into a light engine, it is like an incandescent lamp connected to 220V can light (also need to have its matching heat sink). This will help standardization on the one hand, and the other hand can greatly facilitate the housing (and heat sink) design.
