Laser light source collimating device, collimating device array, lighting system and projection equipment

Abstract

The invention is suitable for the technical filed of optics and provides a laser light source collimating device, a collimating device array, a lighting system and projection equipment. The collimating device comprises an inner sleeve and an outer sleeve, wherein both ends of the inner sleeve are located in the outer sleeve; one end of the outer sleeve is provided with a first opening and the other end of the outer sleeve is provided with a first flange extending inwards; the center axes of the first flange and the first opening are overlapped; one end (close to the first opening) of the inner sleeve is provided with a second opening and the other end of the inner sleeve is provided with a second flange extending inwards; and the upper surface of the second flange presses against the lower surface of the first flange and the second flange is bulged inwards relative to the first flange so as to form a step structure. According to the laser light source collimating device, the collimating device array, the lighting system and the projection equipment, the spacing design and the concentricity design of a laser and a collimating lens are respectively realized through two independent sleeves; the inner and outer sleeves can be individually manufactured thus being convenient to process; and therefore, the collimating device is convenient to process, high in processing accuracy, suitable for batch production and relatively good in laser collimating effect at the same time.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a laser light source collimation device, a collimation device array, an illumination system including the collimation device and projection equipment including the illumination system. Background technique [0002] Laser light sources are often used in light-emitting components of lighting systems. For example, projection systems require high-brightness lighting systems to project light onto imaging components. The lighting part of existing projection systems mostly uses high-pressure mercury lamps, LEDs, and lasers as light sources. Semiconductor laser is a widely used lighting source. The light emitted by a single semiconductor laser has a certain divergence angle, and because the power of a single semiconductor laser is low, it is not enough to achieve the brightness required for projection. Generally, a laser array is required to meet the brightness required for ...
