Problems solved by technology

[0003] Although the photovoltaic anti-reflection diode disclosed above is provided with a heat dissipation base, since the package body and the heat dissipation base are arranged separately, there is a gap between the two, and the heat dissipation effect is not ideal.
[0004] Moreover, the heat dissipation fins are arranged on both sides of the heat dissipation base, and the heat dissipation fins and the inside of the package are separated from the outer wall of the package and the solid part in the middle of the heat dissipation base. The heat conduction distance is too long, resulting in poor heat dissipation effect.
