Abstract: An calibration kit includes a base, a combination of calibration parts, and a manipulation part. The combination of calibration parts is disposed on the base and includes a first calibration part and a second calibration part. The first calibration part has a first calibration surface. The second calibration part has a second calibration surface. The first calibration part and the second calibration part are relatively movable in a movement direction and are movable relative to the base. The manipulation part is movably or rotatably disposed on the base. The manipulation part is configured to be operable to drive the first calibration part and the second calibration part to move in the movement direction relative to the base, so that the combination of calibration parts forms a three-dimensional calibration surface configuration through the first calibration surface and the second calibration surface.

Abstract: A light source module including first and second light sources, first and second wavelength conversion units, first and second light-splitting units is provided. The first light source emits a first light having a first wavelength. The first wavelength conversion unit converts at least one portion of the first light into a first converted light having a second wavelength. The second light-splitting unit allows the light having the first wavelength to travel through and reflects the light having the second wavelength. The second light source emits a second light having the first wavelength. The second wavelength conversion unit converts at least one portion of the second light into a second converted light having the second wavelength. The first light-splitting unit disposed between the first and the second wavelength conversion units reflects the light having the first wavelength and allow the light having the second wavelength to travel through.

Abstract: A projection device includes a plurality of solid-state lighting sources driven by a DC drive power to sequentially provide a first light generated by a first number of light sources, a second light generated by a second number of light sources and a third light generated by a third number of light sources within a response cycle; and a color wheel having a first block, a second block and a third block, respectively corresponding to the first to third lights, so that the projection device sequentially outputs a first color light with a first brightness, a second color light with a second brightness and a third color light with a third brightness. The brightness of the first to third lights is controlled by number of light sources to be turn on.

Abstract: A light source module includes a first light-splitting element, a second light-splitting element, a first light source, a second light source and a third light source. The first light source emits a first light having a first wavelength to the first light-splitting element in a first optical path direction. The second light source emits a second light having the first wavelength to the first light-splitting element in a second optical path direction perpendicular to the first optical path direction. The third light source emits a third light having a second wavelength to the first and second light-splitting elements in a third optical path direction opposite to the second optical path direction, and the second wavelength is different from the first wavelength. The first light source and the second light source include reflection layers configured to reflect light having the first wavelength.
