Illumination device

Abstract

The invention discloses an illumination device. The illumination device comprises a shell, an optical element connected with the shell, a containing cavity formed through cooperation of the shell and the optical element, a light source assembly located in the containing cavity, and a drive power supply assembly located in the containing cavity. The illumination device further comprises a channel located in the containing cavity and penetrating the shell and the optical element. The interior and the exterior of the illumination device are made to communicate with each other through the channel. Heat emitted by the light source assembly in the illumination device can be effectively and rapidly dissipated through the channel, no cooling elements need to be additionally arranged, and the cost and weight of the illumination device are reduced.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a lighting device. Background technique [0002] The current lighting device generally emits irradiating light through an electric-driven light source assembly to illuminate objects, and then adjusts the current supplied to the light source assembly by driving the power supply assembly to adjust the lighting effect of the lighting device. However, during the use of the lighting device, the light source assembly and the driving power supply assembly through which current flows will generate heat, which will cause the reliability of the lighting device to decrease. [0003] Existing lighting devices, especially high-power lighting devices, generally add a heat dissipation structure between the lamp housing and the mask. Most of the heat dissipation structures are made of aluminum alloy, and many fins are closely arranged on it. The structure is complex and the weight i...

However, during the use of the lighting device, the light source components and the driving power supply components passing through the current will generate heat, which will cause the reliability of the lighting device to decrease

[0003] Existing lighting devices, especially high-power lighting devices, generally add a heat dissipation structure between the lamp housing and the mask. Most of the heat dissipation structures are made of aluminum alloy, and many fins are closely arranged on it. The structure is complex and the weight is heavy.

To reduce the temperature of the whole lamp when the high-power lighting device emits light by adding a heat dissipation structure, it not only increases the weight of the entire lamp, but also increases the cost of the lamp
