Problems solved by technology

[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

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 present invention provides a light source system and projection equipment. The light source system includes a first light source, including a first blue laser light source for emitting a first blue laser light source; a red laser light source for emitting red laser light; and a green laser light source A light source, used to emit green laser light; a second light source, including a second blue laser light source; a wavelength conversion element, used to convert the second blue laser light into a subject light; a control device, used to control the first blue laser light color laser light source, the red laser light source, the green laser light source and the second blue laser light source switch, so that the first blue laser, the red laser and the green laser combine to form a light source The light or the first blue excitation light combines with the received light to form the light source light. The light source system and the projection device having the light source system can realize 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.
