摘要： The invention provides a projection device including a first display, a second display, a third display, a light-combining module, a first angle selector, a second angle selector, a third angle selector, and a projection lens. The first display, the second display, and the third display are respectively adapted to provide a first image beam, a second image beam, and a third image beam. The projection lens is configured on one side of a light-outgoing surface of the light-combining module, and is adapted to project the first image beam, the second image beam, and the third image beam out of the projection device. The first image beam, the second image beam, and the third image beam respectively pass through the first angle selector, the second angle selector, and the third angle selector, and are then transmitted to the projection lens by the light-combining module.

摘要： A lighting device (100) and a projection device, comprising a light source for generating a blue excitation light (110), a base board (130), and a wavelength conversion material layer (140) covered on the base board (130). The wavelength conversion material layer (140) absorbs a part of the blue excitation light and emits an excited light. The color coordinate of the excited light is within the pre-configured color area, so that a mixed light combined by the excited light and the remaining blue excitation light not absorbed by the wavelength conversion material layer (140) exits the wavelength conversion material layer (140). The color coordinate of the mixed light is closer to the pre-set blue light color coordinate than the color coordinate of the blue excitation light.

摘要： This disclosure provides a laser speckle-removing optical component, including a beam-shrinking lens group and a diffusion sheet arranged on a laser emergent optical path, where the beam-shrinking lens group includes a first beam-shrinking lens and a second beam-shrinking lens, and the diffusion sheet is located between the first beam-shrinking lens and the second beam-shrinking lens. The arrangement of the diffusion sheet between the first beam-shrinking lens and the second beam-shrinking lens, increases the area of speckles received by the diffusion sheet component, reduces energy density of the light received, and is able to alleviate the accumulation phenomenon of dust particles on the diffusion sheet, therefore, alleviating light attenuation phenomenon, and prolonging the service life of the laser source. This disclosure also provides a double-color laser source, a three-color laser source and a laser projection equipment applying the above laser speckle-removing optical component.

摘要： A color wheel device is used in a projector. The color wheel device includes a housing, a color wheel, a motor, and a thermally conductive member. The housing has at least one through hole for a light beam to pass through. The color wheel is disposed in the housing and includes a substrate and a phosphor layer. The substrate has a light-receiving surface. The phosphor layer is disposed on the light-receiving surface. The light beam forms a light spot on the phosphor layer. The motor is disposed in the housing for driving the substrate to rotate. During the rotation of the substrate, the light spot forms a circular path on the phosphor layer. The thermally conductive member is disposed on the housing substantially at a location to which the circular path maps.

摘要： A projector used a projection lens to enlarge and project image light generated by image generator. When it is assumed that the on-optical-axis position of a lens surface where the maximum of light ray passage ranges (effective diameter) is minimized in the projection lens is a minimum diameter position, a stop is provided on a lens shifted from the minimum diameter position toward the light exiting side. The lens on which the stop is provided is a lens (for example, fourth lens closest to minimum diameter position) that satisfies 0.8φ1≦φ2≦φ1, where φ1 represents the light flux diameter on a surface where the on-axis light flux diameter is maximized, and φ2 is the diameter of the stop.
