Embodiment Construction

[0035] see figure 1 , is a schematic structural diagram of the first embodiment of the light source device of the present invention. Such as figure 1 As shown, the light source device 1 of this embodiment includes a light source module 101, a condenser lens 102a, a first condenser lens group 102b, a second condenser lens group 102c, a spectroscopic device 103, a filter device 104, a light reflection device 105 and a color Wheel module set 106 .

[0036] The light source module 101 is used to emit first light S10 and second light S20 with different polarization directions. In this embodiment, the first light S10 and second light S20 are p-light and s-light whose polarization directions are perpendicular to each other. The spectroscopic device 103 can transmit the first light S10 and reflect the second light S20. The reflective device 105 can receive the second light S20 reflected by the spectroscopic device 103 and convert the polarization direction of the second light S20 t...

Abstract

The invention discloses a light source device and a projection device with the same. The light source device comprises: a light source module configured to emit first light and second light; a light splitting device configured to transmit the first light and reflect the second light; a light reflecting device configured to receive the second light and reflect the second light to the light splitting device; a color wheel module configured to convert the first light to third light and reflect the third light to a light filtering device; and a light filtering device configured to transmit the first light, reflect the third light and transmit the second light which is converted in a polarization direction and reflected by the light reflecting device, wherein the second light and the third light are output after being mixed so as to achieve the purpose of flexible regulation of the luminous flux and the color temperature of the mixed light.

Description

technical field [0001] The invention relates to the field of light source devices, in particular to a light source device and a projection device with the light source device. Background technique [0002] At present, the technology of using a single laser to excite corresponding phosphors and then mixing them into white light has gradually matured. However, the luminous flux and color temperature of white light cannot be adjusted after a single laser excites the color wheel, and the white light output is single, which cannot meet the needs of various scenarios. Contents of the invention [0003] The present invention mainly provides a light source device and a projection device having the light source device, aiming to solve the current problem that the luminous flux and color temperature of mixed white light cannot be adjusted. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is to provide a light source de...
