Abstract

The invention provides a light source projector. The light source projector comprises a fixed substrate, a movable substrate, a light-emitting part and an optical cover plate, wherein the movable substrate is movably connected with the fixed substrate; the light-emitting part is fixedly arranged on the movable substrate and is electrically connected with the movable substrate. The light-emitting angle of the light-emitting part is adjusted through movable connection between the movable substrate and the fixed substrate. The fixed substrate comprises a bottom substrate and a side wall substrate, and the side wall substrate surrounds the light-emitting part and is fixedly arranged on the bottom substrate; the side wall substrate is provided with at least two installation grooves used for installing the optical cover plate, the optical cover plate is arranged in the installation grooves and fixedly connected with the side wall substrate, and light emitted by the light-emitting part is emitted outwards after passing through the optical cover plate. Therefore, by arranging the fixed substrate and the movable substrate which are movably connected, the light-emitting part is arranged on the movable substrate, adjustment of emergent light can be achieved through movable connection between the fixed substrate and the movable substrate, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of packaging, and more specifically, to a light source projector. Background technique [0002] With the rise of 3D sensing technology in recent years, technologies such as face payment and automatic driving have become popular. 3D sensing is mainly composed of light source projectors and receiving devices. The current light source projectors are mainly TOF packaged products, which are mainly composed of a substrate, a laser chip and a uniform optical cover. Usually, the light-emitting surface of the laser chip is parallel to the optical cover, so that the light profile projected from the light source is regular; however, in some scenes, it is often necessary to project some special light-emitting patterns The light pattern is adjustable, but in related technologies, the relative positions of the packaged substrate, laser chip, and optical cover are fixed, and the function of adjusting the projected...
