摘要:
The present invention discloses a color temperature compensation gobo, which comprises a gobo substrate, a light shielding film being attached to the gobo substrate, and the light shielding film being provided with hollowed-out carvings, and a color temperature compensation film being attached to the gobo substrate or the light shielding film and used for compensating for the color temperature of light in an optical path. The present invention further discloses a color temperature compensation system comprising the aforesaid color temperature compensation gobo, a light source and a projection lens, wherein the color temperature compensation gobo is arranged between the light source and the projection lens, and light emitted by the light source sequentially passes through the color temperature compensation gobo and the projection lens to project a pattern with a color temperature conforming to standards. Compared with the prior art, the present invention performs color temperature compensation on the gobo through the color temperature compensation film, so that when imaging is performed by the projection lens, the color temperature of the projected light thereof is basically consistent with the color temperature of projected light that does not pass through the gobo, and the color temperature of the projected light of a light meets the standard. Meanwhile, the present invention has the beneficial effects of a simple structure and high practicability.
