Abstract: A light uniforming component including a light uniforming element and a frame is provided. The light uniforming element has a first side surface. The frame includes a side wall and a first elastic piece. The first elastic piece includes a first section and a second section. One end of the first section is bent and connected to the side wall. The second section is bent and connected to another end of the first section. The light uniforming element is disposed in the frame. A first fold line between the first section and the second section of the first elastic piece contacts the first side surface. A second fold line between the first section and the side wall is not perpendicular to an orthographic projection of an optical axis of the light uniforming element on the side wall. A lighting module and a projector including the light uniforming component are mentioned.

Abstract: A light source module includes a light source, first and second lens elements, a reflector, and a first diffuser. The light source emits a beam focused by the first lens element on a first focal point. The reflector is disposed on a beam transmission path. The first lens element is between the light source and the reflector. The first diffuser is between the first lens element and the reflector and includes a first diffusion plate and a first drive mechanism. The first diffusion plate is at/near the first focal point. The beam is transmitted to the reflector by the first diffusion plate. The first drive mechanism is between the first diffusion plate and the first lens element, and moves/rotates the first diffusion plate. The second lens element has a second focal point, coinciding with the first focal point, at a light-incident side. The reflector is at the light-incident side.

Abstract: An optical engine module comprises a casing, a light valve, a heat dissipating module, and at least three fixtures. The casing comprises at least three fixing structures. The light valve is disposed in the casing and is connected to the casing. The light valve comprises a heat interface. The heat dissipating module comprises a heat dissipating surface in contact with the heat interface of the light valve. The number of the at least three fixing structures and positions of the same correspond respectively to the number of the at least three fixtures and positions of the same. The heat dissipating module is connected to the casing by matching the at least three fixing structures and the at least three fixtures. In the optical engine module, improved stability of the heat dissipating module, preferable heat dissipating efficiency for the light valve, and thus good optical effect are provided.

Abstract: An optical engine module including a casing, a light valve, and a compensating module is provided. The casing includes an opening. The light valve includes an active surface and is disposed on the casing. The active surface of the light valve is exposed from the opening of the casing and is used for providing a light beam. The compensating module is disposed on the casing and includes an optical compensating element located on a transmission path of the light beam and a heat dissipating support for holding the optical compensating element. When a portion of the active surface is in a first state, the light beam is transmitted to and passes through the optical compensating element. When a portion of the active surface is in a second state, the light beam is transmitted to the heat dissipating support. The optical engine module provided by the disclosure provides good optical effect.
