A light source fixing assembly includes an optical engine housing, a circuit board, a light emitting element, a flexible circuit board, a fixing element and an abutting element. The circuit board has a bearing surface, a first fixing region and a first conductive bonding region. The first bonding region and the light emitting element are on the bearing surface. The flexible circuit board is between the optical engine housing and the circuit board. The flexible circuit board has a first surface, a second surface opposite to the first surface, and a second fixing region. The second surface has a second bonding region. The fixing element fixes the circuit board and the flexible circuit board onto the optical engine housing. The abutting element abuts against the flexible circuit board and corresponds to the second bonding region, so that the first bonding region is electrically connected to the second bonding region.

Light source fixing assembly and projection device

An adjustable optical module including a housing, an optical component and a cover component is provided. The housing has a positioning slot and an opening. The optical component is rotatably disposed on the positioning slot and includes an optical film and a carrying base for carrying the optical film. The carrying base includes an adjusting lever corresponding to the opening, and the adjusting lever is adapted to adjust an angle of the optical film. The cover component is fixed on the housing and covers the opening, and the cover component presses against the adjusting lever to fix the optical film. A projector having the adjustable optical module described above is also provided. The adjustable optical module and the projector of the invention can adjust the angle of the optical film through the above structures.

Adjustable optical module and projector

A projection apparatus includes a projection unit, a base and a pivoting member. The projection unit includes a light source, a light valve and a lens. The light source provides an illumination beam, the light valve converts the illumination beam into an image beam, and the lens projects the image beam. The base is connected to the projection unit and has at least one first stopping portion. The pivoting member is pivoted to the base and has at least one second stopping portion. The pivoting member is adapted to connect to an external power supply device, the base and the pivoting member are adapted to relatively rotate so as to adjust an angle of the projection image.

Projection apparatus with device for adjusting projection angle of projection image

A projection device including a housing, an optical engine, and a power connector is provided. The housing has a front end portion, a rear end portion opposite to the front end portion, and a projection opening. The optical engine is disposed within the housing and includes a projection lens, a first light-emitting element, and a second light-emitting element. The projection lens is adapted to output an image beam through the projection opening. The first light-emitting element and the second light-emitting element are respectively thermally coupled to a first coupling portion and a second coupling portion of the housing. The housing has a heat separation for separating the first coupling portion and the second coupling portion. The power connector is connected to the rear end portion.

Projection device

A heat dissipation module includes a base, a lamp, a fan, an orientation-sensing element and a motor. The lamp is disposed on the base, and the fan is disposed on the base for inducing an air flow and cooling down the lamp. The orientation-sensing element generates an orientation signal, and the motor rotates the base according to the orientation signal to allow the base to be substantially parallel to a horizontal plane. A rotational axis of the motor is substantially aligned with a central axis of the lamp.
