Lamplight filtering structure and stage decoration LED lamp

Abstract

The invention provides a light filtering structure. The light filtering structure comprises a light source, a filtering color-change plate and a heat insulation plate; the light source irradiates the filtering color-change plate which is located in front of the light source; a color filter piece is arranged on the filtering color-change plate; light emitted by the light source flows through the color filter piece on the filtering color-change plate to be processed into light of different color; the color filter piece is annularly mounted on the filtering color-change plate; one end of the color filter piece, close to the center of the filtering color-change plate is used as the inner end of the color filter piece; the inner end of the color filter piece protrudes toward one end of the light source, so that the color filter piece is in a special inclination angle relative to the front end surface of the light source; the heat insulation plate which is in an inclined angle relative to the light source is arranged between the light source and the filtering color-change plate; the thickness of the heat insulation plate is gradually raised from the center to the edge.

Description

technical field [0001] The invention relates to a light filtering structure, in particular to a light filtering structure of a stage decorative light. Background technique [0002] In various entertainment places, such as dance halls, bars and other places, lighting equipment is often used to add atmosphere. At present, a common stage decoration light is to set a color filter in front of the light source. When the light source is turned on, the color filter will project the light from the light source, so as to obtain a colored beam or spot on the scene. Existing light filters used on stage decoration lights are generally made of colored glass sheets and light-transmitting colored plastic sheets. In use, due to the high temperature of the stage decoration lamp, the existing stage lighting lamps have the disadvantages of easy damage and aging, and short service life. [0003] Aiming at such a problem, 201210289242.8 proposes a stage lighting color filter device, which makes...

Problems solved by technology

However, in this invention, since a heat shield is arranged between the lamp body and the color filter belt, the intensity of the light emitted by the lamp body is affected, resulting in dimming of the projected light and affecting the lighting effect.
