Embodiment Construction

[0026] see figure 1 , figure 1 It is a schematic diagram of the light source system 100 provided by the first embodiment of the present invention. The light source system 100 includes a first light source 110, a second light source 120, a wavelength conversion element 180, a control device 125, an adjustment device 130, a first light splitting and combining element 140, a relay lens 150, a second light splitting and combining element 160, and a collection lens Group 170 and uniform light device 190 . The first light source 110 and the second light source 120 are located on the same side of the wavelength converting element 180 .

[0027] Wherein, the first light source 110 includes: a first blue laser light source 111 for emitting a first blue laser light (465nm), a red laser light source 112 for emitting a red laser light (639nm), and a red laser light source 112 for emitting a green laser light (520nm). Green laser light source 113. The second light source 120 includes a...

Abstract

The invention provides a light source system and a projection device. The light source system comprises a first light source comprising a first blue laser light source for emitting first blue laser light, a red laser light source for emitting red laser light and a green laser light source for emitting green laser light. The light source system also comprises a second light source comprising a second blue laser light source, a wavelength conversion element for converting second blue laser light into stimulated light, and a control device for controlling the switching of the first blue laser light source, the red laser light source, the green laser light source and the second blue laser light source such that the first blue laser light, the red laser light and the green laser light are combined to form light source light or the first blue laser light and the stimulated light are combined to form the light source light. The light source system and the projection device with the light source system can achieve dynamic color gamut adjustment.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to a light source system and projection equipment. Background technique [0002] This section is intended to provide a background or context for the implementation of the embodiments of the invention that are set forth in the claims and detailed description. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In general, the color gamut requirements that projection or projection equipment need to support are different for different occasions. Among existing projection equipment, a projection equipment can generally only support one of the color gamut standards in the existing projection field, such as , only supports the DCI color gamut or only supports the Rec.2020 color gamut, and cannot realize the dynamic color gamut adjustment of multiple color gamuts on one projection or projection device. Contents of the invention [0004] T...
