Both the light-emitting assembly and the refrigeration assembly need to dissipate heat, but they share the same air duct. Since the heat dissipation temperatures of the light-emitting assembly and the refrigeration assembly are different, the heat between them is mixed and mutually affected, resulting in a poor heat dissipation effect.
