Abstract

The invention discloses a water cooling type movie projection lamp. The water cooling type movie projection lamp comprises a shell and a lamp rack and is characterized in that the lamp rack is horizontally arranged on the lateral wall of the shell and fixedly connected with the shell through screws, the top of the lamp rack is provided with a sealing plate, the sealing plate is vertically arrangedon the edge of the top of the lamp rack and tightly and fixedly attaches to the lamp rack, a lamp holder is arranged on the lateral side of the lamp rack, the lamp holder is vertically arranged on the lateral wall of the lamp rack and fixedly connected with the lamp rack through screws, a fixing column is arranged at the bottom of the lamp rack, and the fixing column is vertically arranged on theedge of the bottom of the lamp rack and tightly and fixedly attach to the lamp rack. The water cooling type movie projection lamp has the advantages that the water cooling type movie projection lamphas a water cooling system, water is conveyed to the periphery of the lamp rack through a WQY300 water pump to cool the lamp rack, and accordingly the service life of the water cooling type movie projection lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of movie projection lamps, in particular to a water-cooled movie projection lamp. Background technique [0002] Movie projector, an optical machine for showing movies, is composed of a light box, an optical system, a transmission film feeding device, and a film supply box. The movie runs on the projector at 24 frames per second. The interval of 1 second is evenly turned on and off once, so each frame is clearly projected onto the screen twice through the projection lens under the transmission of the light source. Although it is 24 frames per second when filming, it is equivalent to 48 frames per second, due to the persistence of vision of the human eye, the rapid change of the picture enables the audience to obtain the visual effect of activities, and film projection lights are needed during the projection. [0003] Most of the existing movie projection lamps dissipate heat slowly through the surrounding en...
