Problems solved by technology

However, the above-mentioned lamps have certain limitations. For example, the pattern lamp can only project a fixed pattern. Due to the limited frequency of the galvanometer, the final effect of the laser lamp is severe flickering and the resolution is very low, which cannot be compared with ordinary projectors.
However, whether the existing ordinary projectors use liquid crystal (LCD), digital light processing (DLP) or liquid crystal on silicon (LCoS) technology, they are all based on the principle of shielding unnecessary light. In some cases, the brightness of the required light source will be very high, resulting in too high a cost to realize

Embodiment Construction

[0033] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0034] figure 1 A structural block diagram of the holographic projection lighting system of this embodiment is shown, including: a light source 11 , a light source shaper 12 , a spatial light modulator 13 , an image amplifier 14 , a control module 15 and a power supply 16 .

[0035] Wherein, the light source 11 is used to provide light required for illumination, which can be implemented by using lasers, light emitting diodes (LEDs) and the like. The light source 11 is optional, and the holographic projection system may integrate the light source 11 inside, or use an external light source 11 .

[0036] The light source shaping module 12 modulates the light beam emitted by the light source 11 to required preset parameters to meet the requirements of holographic lighting...

Abstract

The invention provides a holographic projection lighting system. The system comprises a light source shaper which modulates a light beam sent out by a light source to preset parameters, a spatial light modulator which is coupled with the light source shaper, modulates the light beam based on an input holographic image and restores an original image, and a control module which is connected with the spatial light modulator and provides the holographic image to the spatial light modulator. According to the invention, the requirement for the brightness of the light source can be reduced, which is conducive to reducing the device cost.

Description

technical field [0001] The invention relates to a holographic projection lighting system, in particular to a holographic projection lighting system applied to landscape lighting, stage lighting and projection. Background technique [0002] Stage lighting equipment and landscape lighting equipment are used in theatrical performances and occasions that require lighting effect display, which can produce gorgeous visual effects. Existing stage lamps are divided into several types such as gobo lights, laser lights, and scanning lights. Gobo lights can project dozens of patterns and colors through the combination of color wheels and gobo wheels. The laser light projects pre-programmed patterns through the principle of galvanometer scanning. However, the above-mentioned lamps have certain limitations. For example, the pattern lamp can only project a fixed pattern. Due to the limited frequency of the galvanometer, the final effect of the laser lamp is serious flickering and the res...
