摘要： A light source module includes a light source, a wavelength conversion unit, a diffuser, and a reflector. The light source is configured to emit excitation light. The wavelength conversion unit is configured to reflect the excitation light. The diffuser has a first side and a second side opposite to each other, and is configured to allow the excitation light reflected by the wavelength conversion unit to enter the diffuser from the first side and reach the second side. The reflector is configured to reflect the excitation light entering the diffuser, so that the excitation light propagates from the second side to the first side and leaves the diffuser.

摘要： A mercury lamp cooling system includes a tilt sensor, a controller, a first and second blowers and a flow guiding structure. The flow guiding structure includes a first and second flow channel and two flow switch devices. The controller is electrically connected to the tilt sensor, the first and second blower and two flow switch devices. The first flow channel includes a first opening facing the first blower and a second and third opening facing the mercury lamp. The second flow channel includes a fourth opening facing the second blower and a fifth and sixth openings facing the mercury lamp. The controller controls the flow switch devices based on a tilt angle of a projector such that the air flow passes through at least one of the second and third opening and at least one of the fifth and sixth opening.

摘要： A laser light source module includes a laser source, a connecting unit, a controlled switch unit, and a verification unit. When a verification signal is received, the verification unit judges whether the verification signal complies with a verifying condition. If the verification signal complies with the verifying condition, the controlled switch unit is in the on state, so that a first output voltage is transmitted to the laser source through the controlled switch unit to drive illumination of the laser source. Whereas, if the verification signal does not comply with the verifying condition, the controlled switch unit is in the off state, so that the first output voltage fails to be transmitted to the laser source through the controlled switch unit and the laser source is turned off.

摘要： A projector includes a light-emitting device, a color wheel, a notch filter, a switching device, and a light controller. The light-emitting device is configured to emit a light. The color wheel is disposed on a path of the light and is configured to produce lights with different color wave bands. The notch filter has two cut-off waveband, and each is located between adjacent two of the color wavebands. The switching module is configured to move the notch filter to or away the path of the light. The light controller is electrically connected to the light-emitting device and the switching module, and is configured to control an intensity of the light emitted by the light-emitting device.
