Abstract: A light source module includes a solid-state light emitter, a reflective mirror, a light integration box, and a light sensor. The solid-state light emitter is configured to emit light. The reflective mirror is configured to turn a first part of the light and allow a second part of the light to pass. The light integration box is disposed in a path of the second part of the light and has an entrance. The second part of the light passes through the entrance to enter into the light integration box and is uniformly mixed in the light integration box. The light sensor is disposed on the light integration box to receive the second part of the light.

Abstract: A projection system includes a light source module, an image device, a first light sensor, a second light sensor, and a processor. The light source module has at least one solid-state light-emitting device. The processor is communicatively coupled to the light source module, the first light sensor, and the second light sensor and is configured to execute a calibration procedure.

Abstract: A light source module includes a first light-emitting unit, a second light-emitting unit, a first dichroic mirror, and a wavelength conversion unit. The first light-emitting unit emits a first color light. The second light-emitting unit emits a second color light. The first dichroic mirror allows the first color light to transmit through and has a passing area. The passing area allows the second color light to pass through. The wavelength conversion unit includes a substrate and a phosphor layer disposed on the substrate. The phosphor layer converts the first color light transmitting through the first dichroic mirror into a third color light, and reflects and scatters the second color light passing through the passing area. The first dichroic mirror reflects the second color light reflected by the wavelength conversion unit and the third color light.

Abstract: A projection system is provided, which includes a first light source, a second light source, a wavelength converter, a first light splitting element, and a second light splitting element. The first light source is configured to emit a first light. The second light source is configured to emit a second light. The wavelength converter is configured to convert portions or all of the second light into a third light. The third light includes a red light and a green light. A wavelength range of the first light is within a wavelength range of the red light. The first light splitting element is configured to permit the first light to pass through or to be reflected. The second light splitting element is configured for removing a portion of the first light or not removing the first light.
