Title:
COLOR TEMPERATURE COMPENSATION GOBO, AND COLOR TEMPERATURE COMPENSATION SYSTEM AND COLOR TEMPERATURE COMPENSATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/128352
Kind Code:
A1
Abstract:
Disclosed is a color temperature compensation gobo, comprising a gobo substrate and a light blocking film. The light blocking film is adhered to the pattern sheet substrate and is perforated. The color temperature compensation gobo also comprises a color temperature compensation film. The color temperature compensation film is adhered to the gobo substrate or the light blocking film and is used to perform color temperature compensation on light in an optical path. Also disclosed is a color temperature compensation system provided with the color temperature compensation gobo. The color temperature compensation system comprises a light source and a projection lens. The color temperature compensation gobo is provided between the light source and the projection lens. Light emitted by the light source passes sequentially through the color temperature compensation gobo and the projection lens, such that a pattern with a required color temperature is projected. Compared with the prior art, the present invention performs color temperature compensation on the gobo by means of the color temperature compensation film, such that when the projection lens projects an image, the color temperature of projected light is substantially the same as the color temperature of projected light not passing through the gobo, and the color temperature of projected light of a lamp conforms to a standard. The present invention has a simple structure and is practical.
