Abstract

The invention discloses a stage lighting color filter device which comprises a color filter wheel and a lamp body. The color filter wheel is located in front of the lamp body, a color filter strip is arranged around the center of the color filter wheel, one end of the color filter strip close to the center of the color filter wheel serves as an inner end of the color filter strip, the inner end of the color filter strip is protruded towards one side of the lamp body, so that the color filter strip has an angle of inclination relative to the front end face of the lamp body, and the lamp body is opposite to the color filter strip. The stage lighting color filter device can lower temperature of a central zone of the lamp body and prolongs service life of the lamp body.

Description

technical field [0001] The invention relates to a light color filter device, in particular to a stage light color filter device capable of reducing the temperature in the center area of ​​a lamp body. Background technique [0002] Most of the existing stage lighting color filter devices are provided with a color filter disc in front of the lamp body, and a color filter is fixed on the color filter disc, and the color filter and the front end of the lamp body are generally arranged in parallel, so that The structure will make part of the light emitted by the lamp body reflect back to the central area of ​​the lamp body, which will increase the temperature of the lamp body, easily cause the lamp body to burn out, and reduce the service life of the lamp body. Contents of the invention [0003] Based on this, the present invention overcomes the defects of the prior art and provides a color filter device for stage lights, which can reduce the temperature in the central area of ...
