Description

Technical Field

[0002] As we all know, LED lights have high temperature characteristics when working, and this is especially true for the light sources used in professional stage lights. Their power is generally high, which will generate a lot of heat. If it cannot be dissipated in time, it will cause irreversible damage to the light source. Excessive light source temperature will directly lead to reduced light source efficiency and thermal corrosion and burning of electronic components. Therefore, the stage light source module needs to dissipate excess heat in time.
