after flowing to the front surface of the base 40, the air flows into the front case 10 through the first type ventilation holes 12, and then flows into the heat dissipating main body through the second type ventilation holes 26. The heat generated by the base 40 is transferred to the outer shell 23 through the first sleeve 24 and the first heat-dissipating ribs 21, and is also transferred to the second sleeve 25 through the first sleeve 24 and the second heat-dissipating ribs 22.

The air flowing out from the heat dissipation holes 34 can exchange heat with the third type heat dissipation ribs 33, so that the temperature of the power supply part is reduced, and the service life of the lamp is prolonged as a whole.

Of course, if no external air flow flows into the front surface of the lamp cap 40, since the heat generated by the lamp cap 40 is dissipated through the heat dissipating body, the air density changes accordingly after the air absorbs heat, and the air itself can also form an air flow.
