Abstract

The present invention discloses a filter coating and a lamp filtering device. The filter coating is made by alternately overlaying a high-refraction material layer and a low-refraction material layer, wherein the optics thickness of each high-refraction material layer and each low-refraction material layer is different, partial wave band light can be filtered, and the light with required special wave band can be transmitted, so that the light with required color may be transmitted through the irradiation of a common light source. The filter coating is applied to a lamp and is formed by direct deposition on glass or organic glass lampshade through a vacuum vapor plating or sputtering mode and a lampshade with the filter coating is formed to allow a common lamp to emit prunosus light, and the filter coating is formed by direct deposition on glass or organic glass lamp frame or lamp ring through a vacuum vapor plating or sputtering mode and the lamp frame or the lamp ring with the filter coating is formed to allow the side wall of the common lamp to emit colorful light; and moreover, the color emitted by the lamp itself cannot be changed, the filter coating and the lamp filtering device are used for people to illuminate and beautifying the lamp.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a filter film and a filter device for lamps. Background technique [0002] Filter film refers to the film layer that attenuates the light intensity or changes the spectral composition. Commonly used are infrared cut filter film, ultraviolet cut filter film and so on. However, there is no filter film on the market that can transmit colored light applied to lamps. In the prior art, lamps that emit colored light are generally realized by RGB light sources. Contents of the invention [0003] The main purpose of the present invention is to provide a filter film that transmits purple-red light and a lamp filter device that is simple in structure and easy to assemble and can present purple-red light. [0004] The present invention proposes a filter film, which is a multi-layer optical cut-off filter film that transmits purple-red light. The high-refraction material layer and the low-refraction m...
