Abstract
A color wheel module includes a fixing bracket, a carbon-iron alloy bracket, a motor, an optical filter, a first damper, and a second damper. The carbon-iron alloy bracket is fixed to the fixing bracket. The motor is fixed to the carbon-iron alloy bracket, and the motor is connected with the optical filter, so as to drive the optical filter to rotate between the motor and the fixing bracket. The first damper is disposed between the carbon-iron alloy bracket and the fixing bracket. The second damper is disposed between the motor and the carbon-iron alloy bracket.
Claims11
A color wheel module, comprising:
- a fixing bracket;
- a carbon-iron alloy bracket;
- a motor;
- a light filter;
- a first damper;
- and
- a second damper,
- wherein the carbon-iron alloy bracket is fixed to the fixing bracket, the motor is fixed to the carbon-iron alloy bracket, and the motor is connected with the light filter, so as to drive the light filter to rotate between the motor and the fixing bracket,
- wherein the first damper is disposed between the carbon-iron alloy bracket and the fixing bracket, and
- wherein the second damper is disposed between the motor and the carbon-iron alloy bracket.
A projection apparatus, comprising:
- a casing;
