Abstract

The invention relates to the technical field of projectors and provides a projector with a heat dissipation bulb socket. The invention aims to solve the problem of poor heat dissipation effect of bulbs of conventional projectors. The projector comprises a shell. A bulb, a light modulation device used for modulating light emitted from the light source device according to image information and a projection lens used for projection of light speed obtained through modulation of the light modulation device are arranged in the shell. The bulb is provided with a bulb socket body comprising a first metal drum and a second metal layer; the inner wall of the first metal drum is provided with a thread matching a threaded head of the bulb; the bottom of the first metal drum is provided with a through hole and an insulation ring is clamped in the through hole; the insulation ring is provided with an electric conduction pillar in the middle; a vacuum steam cavity is formed between the first metal drum and the second metal layer; the inner wall of the steam cavity is provided with a liquid absorbing core; the steam cavity is filled with working fluid; the first metal drum is connected with a conductor; the outer wall of the second metal layer is wrapped in a ceramic insulation layer.

Description

technical field [0001] The invention belongs to the technical field of projectors, and specifically discloses a projector with a heat dissipation bulb holder.
