As shown in FIGS. 1 to 3 , the present invention discloses a lamp housing, which is applied to a lamp. The disclosed lamp housing includes a cylindrical housing 100 and a radiator 200 .

The cylindrical casing 100 can provide installation positions for other components of the lamp. Specifically, the cylindrical casing 100 has an inner cavity 110 that can accommodate other components of the lamp.

The heat sink 200 can transfer part of the heat generated by the light emitting module 300 in the lamp, so as to prevent the light emitting module 300 from being damaged due to the high temperature of the lamp housing.

Specifically, in the embodiment of the present invention, the radiator 200 is arranged in the inner cavity 110, a cavity 111 is formed between the radiator 200 and the cylindrical casing 100, and the side wall of the cylindrical casing 100 is provided with a first air inlet 120, The port at the first end of the cylindrical casing 100 includes a second air inlet 130, and the second end of the cylindrical casing 100 is provided with an air outlet 140.

When the above-mentioned lamp housing is applied to a lamp, part of the heat generated by the light-emitting module 300 in the lamp is transferred to the radiator 200 during the specific working process. Based on this, the cold air passes through the first air inlet 120 and the second air inlet. 130 enters the cavity 111, and further, the cold air contacts the radiator 200, so that the radiator 200 is cooled by the cold air, and at the same time, the hot air generated by the contact with the radiator 200 flows through the air outlet 140 out of cavity 111 . Such continuous circulation can dissipate heat for the light emitting module 300 , thereby preventing damage to the light emitting module 300 .
