A light sensor includes an optoelectronic device and a light guide element. The light guide element has a first light incident surface and a light exit surface, so as to allow an incident light to enter the light guide element from the first light incident surface and then exit to the optoelectronic device from the light exit surface; wherein at least one of the light incident surface and the light exit surface has a single curved surface.

Light sensor

According to one embodiment, an image projection device is provided. The image projection device includes an opto-mechanical module, a projection lens, and a lens adjusting mechanism. The opto-mechanical module is used for generating an image light. The projection lens is located on the path of the image light. The lens adjusting mechanism includes an outer ring rotating member, a transmission strip, a first fastener, and a driving mechanism. The outer ring rotating member is disposed on the projection lens, and the outer ring rotating member is used to drive the projection lens to rotate along an axis. The transmission strip surrounds the outer ring rotating member on the projection lens. The first fastener is fixedly connected to the transmission strip and the outer ring rotating member. The driving mechanism is connected to the transmission strip to drive the transmission strip and the outer ring rotating member to rotate.
