Problems solved by technology

[0003] People want the place to be illuminated to have sufficient illuminance, but when the place to be irradiated gets enough illuminance, the quality of the projected picture from the lighting system will decrease.
Especially when the lighting system projects the projection screen onto the wall, there will be phosphor yellow spots in the projected light spots, which will affect the use effect of the lighting system

Abstract

The embodiment of the invention provides a lighting device, a pattern lighting device and a pattern lighting system, and relates to the technical field of optical systems. The lighting device comprises a light-emitting element, a light constraining element and a homogenizing element, wherein the light-emitting element is used for providing an emergent light beam; the light constraining element is configured on a transmission light path of the emergent light beam of the light-emitting element so as to constrain an emergent angle of the emergent light beam to be within a preset range; and the homogenizing element is arranged on the transmission light path of the emergent light beam of the light-emitting element, and the homogenizing element is movably cut in or cut out of the transmission light path. The pattern lighting device comprises the lighting device and a pattern plate, wherein the pattern plate is arranged on a downstream light path of the lighting device so as to receive light emitted from the lighting device. The pattern lighting system comprises the pattern lighting device and a projection lens, wherein the projection lens is arranged on a downstream light path of the pattern plate. The lighting device can improve the color uniformity of a projection picture, eliminate miscellaneous spots and solve the problem that the high illuminance and the color uniformity of the projection picture cannot be considered at the same time.

Description

technical field [0001] The present application belongs to the technical field of optical systems, and more specifically, relates to an illuminating device, a pattern illuminating device and a pattern illuminating system. Background technique [0002] With the development of lighting technology, more and more light emitting diodes (light emitting diode, LED) and laser light sources are used in stage lighting systems. [0003] People hope that the place to be illuminated has sufficient illuminance, but when the place to be irradiated has sufficient illuminance, the quality of the projected picture emitted by the lighting system will decrease. Especially when the lighting system projects the projection picture onto the wall, there will be yellow specks of fluorescent powder in the projected light spots, which will affect the use effect of the lighting system. Contents of the invention [0004] The purpose of the present application includes, for example, providing a lighting...
