Heat dissipation device and high-power electric light source

A high-power electric light source comprising:

• an electric light source shell;
• a driving power supply;
• a luminescent device;
• a heat dissipation device comprising a main radiator comprising a heat dissipation body and a heat dissipation mechanism, the heat dissipation body has a mounting surface and a junction surface, the mounting surface is used to mount a heat source surface of the electric light source, the heat dissipation mechanism comprising a plurality of radiating fins arranged on the junction surface which extends substantially in the left-right direction at intervals and collectively forms a heat dissipation channel extending in the left-right direction, the heat dissipation mechanism is provided with a first avoidance space, in which the junction surface has a center line perpendicular to an extension direction of the radiating fin, and left and right parts of the main radiator bounded by the center line have a same heat dissipation capacity in a natural state, and the first avoidance space is arranged on the right side of the center line;
• at least one radiator fan is provided that is installed in the first avoidance space and is used for radiating the airflow flowing from left to right in the heat dissipation channel;
• and wherein the electric light source shell is connected to the heat dissipation device and forms a heat dissipation cavity together with the main radiator, the electric light source shell is provided with an inlet air hole and an outlet air hole at left and right ends of the heat dissipation channel;
• the luminescent device comprises a bottom luminous module and a bottom lamp cover;
• the bottom luminous module is installed on the mounting surface and the bottom lamp cover is installed at the bottom of the main radiator.
