The disclosure provides a hybrid light source system, the hybrid light source system includes a first light source group, a second light source group, and a bandpass filter. The first light source group and the second light source group emit light beams which are the same in color and different in wavelength range. An emergent direction of a light beam of the first light source group and an emergent direction of a light beam of the second light source group are perpendicular to each other. The bandpass filter is arranged on emergent light paths of the first light source group and the second light source group, an angle of 45 degrees is formed between the emergent direction of the light beam of the first light source group and the bandpass filter.

Hybrid light source system and projection display device

The present application relates to the field of projection technology and discloses a phosphor wheel, a light source module, and a projector. A phosphor wheel includes a base, a first phosphor layer, and a second phosphor layer. The base includes an excitation light reflecting section and an excitation light transmitting section. The first phosphor layer is disposed on a surface of the excitation light reflecting section facing a direction of incident light and spreading along a circumferential direction of the base. The second phosphor layer is disposed on a surface of the excitation light transmitting section facing away from the direction of incident light and spreading along a circumferential direction of the base. The first phosphor layer and the second phosphor layer are offset to each other in a radial direction of the base.

Phosphor wheel, light source module and projector

Disclosed is a non-coaxial projection light source system including a light source, a fluorescent wheel, and a converging shaping lens group located between the light source and the fluorescent wheel. Excitation light emitted by the light source is emitted to the converging shaping lens group in an optical axis direction inclined to the converging shaping lens group and then is emitted to the fluorescent wheel. Radiating fluorescent light generated by excitation on the fluorescent wheel is emitted to the converging shaping lens group and then is converged to a light path direction different from the excitation light to be output.

Non-coaxial projection light source system

A light source system, comprising a first light source, a first wavelength conversion device, a second wavelength conversion device, a light path conversion element, and a light combining unit. The light path conversion element is configured to make an excitation light emitted by the first light source irradiate the first wavelength conversion device and the second wavelength conversion device in turn, so as to correspondingly excite and generate a first excited light and a second excited light. The light combining unit is configured to combine the first excited light and the second excited light. A projector system, comprising the light source system.
