    摘要： A lens array includes an edge lens region provided with multiple first type lenslets, a middle lens region provided with multiple second type lenslets and a center lens region provided with multiple third type lenslets. One of the first type lenslets has a first curved surface with a first vertex, one of the second type lenslets has a second curved surface with a second vertex, and one of the third type lenslets has a third curved surface with a third vertex. A first tangent plane to the first curved surface at the first vertex, a second tangent plane to the second curved surface at the second vertex, and a third tangent plane to the third curved surface at the third vertex are parallel to or coincide with each other.

    摘要： A headlight using an image light source is provided, which includes a laser light source and a wavelength converter. The laser light source includes multiple light-emitting units arranged in an array to provide an image beam. The wavelength converter is arranged downstream of an optical path of the laser light source. The wavelength converter is provided with a light dot matrix with the number of rows and columns greater than or equal to 40×40 to excite a part of the image beam into an excitation beam, and an unexcited part of the image beam is mixed with the excitation beam to generate a white beam.

    摘要： A heat dissipation device for a projector includes a light source, a light valve, a prism set, a shading element, and a projection lens. The light source emits a light beam. The light valve is disposed downstream of a light path of the light source to receive the light beam, convert a part of the light beam into image light and another part of the light beam into an ineffective light beam. The prism set includes at least one prism, receiving the image light and the ineffective light beam. The shading element includes a heat dissipation part and is disposed downstream of a light path of the prism set and used to block the ineffective light beam from the prism set. The projection lens is disposed downstream of the light path of the prism set.

    摘要： An optical lens includes an aperture, a first lens, a second lens, a third lens, and a fourth lens sequentially in a direction. One of the first lens and the second lens has positive refracting power, and the other has negative refracting power. The third lens has refracting power, and is a lens with a largest diameter in the optical lens. The fourth lens has the refracting power. The four lenses are made of glass. For light having a wavelength of 1315 nm, a transmittance of the optical lens is greater than ninety percent.

    摘要： A vehicle lamp device includes a matrix-type image light source, a projection lens, an aperture stop and a vehicle lampshade. The projection lens is disposed downstream from and in a light path of the image light source, and the projection lens consists essentially of two or three lenses with refractive powers. The aperture stop is disposed between two outermost lenses respectively at two opposite ends of the projection lens. Two outermost lens surfaces at the two opposite ends of the projection lens have a first optical center and a second optical center respectively, and a distance between the first optical center and the second optical center is in a range between 30 mm and 85 mm.
