First of all, let us know a basic concept. LED, also known as diode, is a solid-state semiconductor device that can convert electrical energy into visible light. So what advantages does LED lighting have? The advantages of LED lighting fixtures mainly lie in their small size, low power consumption, long service life, high brightness, low heat, environmental protection, sturdiness and durability.
 Generally, LED can be regarded as a "cold" light source, because its spectrum does not have a lot of infrared radiation like incandescent lamps, so its light does not generate a lot of heat. However, the LED still generates considerable heat on its PN junction, and this heat must be scattered through convection and conduction. When the LED is installed in a sealed and small lamp to work, it will cause a rapid rise in the PN junction temperature, which will reduce the performance of the system. The use of a heat sink substrate for the LED to dissipate heat and work at a low ambient temperature can increase the light output And prolong life.
