More Information
Summary:The invention provides a projector, including a curvature light device, an image modulation device, and a project lens. The curvature light device is used for generating a beam of light. The image modulation device is used for selectively modulating the beam of light. The projection lens is used for projecting the beam of light modulated by the image modulation device. Further, the curvature light device includes a curved surface, where a plurality of diode light-emitting devices are disposed. Each of the diode light-emitting devices includes a red light LED, a green light LED, and a blue light LED. By a control circuit coordinating with the image modulation device to control the LEDs of the diode light-emitting devices to emit, the projector of the invention can shrink its volume and maintain high illumination without a light integration device and a color wheel.
