A multifunctional linear tunnel light and its housing are disclosed. The housing includes a shell, which is a semi-closed structure consisting of a bottom surface and side surfaces, with an open top and open ends. The bottom surface of the shell has an outwardly protruding section in the middle, with a hollow center forming a groove that communicates with the inner cavity of the shell. The bottom surface of the shell on both sides of the protruding section consists of two symmetrical planar segments with symmetrically arranged slots on their inner surfaces. The outer surface of each planar segment has guide grooves for guiding the mounting bolts of the support bracket. The side surfaces include a first inclined surface, a second inclined surface, and a first vertical surface. The inner surface of the second inclined surface has a light source plate mounting slot, with the slot opening facing the bottom surface of the shell. A baffle is located at the end of the upper groove wall of the light source plate mounting slot. The end of the second inclined surface has a second vertical surface parallel to the first vertical surface, with a snap-fit ​​groove on its inner surface. This utility model integrates two mounting positions with different light emission methods, allowing for selection of one mounting position according to lighting needs, providing flexibility and meeting the needs of different application scenarios.

This utility model relates to the field of medical equipment technology, and specifically discloses an auxiliary lighting device for proctological examination. A height-adjustable bracket is slidably mounted on a support frame, and an angle-adjustable cantilever is rotatably mounted on the bracket. An annular cover is fixedly mounted on the cantilever, and LED light groups for illumination are evenly fixedly mounted on the annular cover. A frosted ring is fixedly mounted on the annular cover, a first retaining ring is fixedly mounted on the bracket, and a second retaining ring is slidably mounted on the cantilever. A spring is installed on the side end of the second retaining ring, and a one-way threaded rod is rotatably mounted on the support frame. The cantilever can be suspended at any angle. When the LED light groups are powered on, they illuminate through the frosted ring, which makes the light emitted by the LED light groups softer. The light can be seen through the central area of ​​the annular cover, achieving a user-friendly effect.

The utility model discloses an LED lamp which comprises a hanging rod, a glass cover and switching cylinders, the glass cover and the switching cylinders are arranged on the hanging rod in a sleeved mode, the switching cylinders are connected to the lower end of the glass cover, every two adjacent switching cylinders are connected through the switching cylinders, cavities are formed in the switching cylinders, and LED lamps are arranged on the side walls of the cavities. Compared with the prior art, the novel lamp string has the beneficial effects that the LED lamps are arranged in the adapter tube at the top end of the glass cover and are shielded by the cover plate, and compared with a traditional lamp string in which the LED lamps are directly distributed on lamp wires, the novel lamp string can reduce the light intensity and make the light softer.

The application belongs to the technical field of shutter, and particularly relates to a solar energy intelligent window capable of converting diffuse light, aiming at the problem that in the existing low-end shutter, the shutter plates are generally continuously controlled, it is inconvenient to separately control the shutter plates, and the control mode is not convenient enough, and the scheme comprises a shutter body, a plurality of shutter plates are rotatably installed in the shutter body, one end of the shutter plate penetrates into a transmission cavity to be connected with a rotating shaft, a first gear is fixed on the rotating shaft, an upwardly-inclined chute assembly is fixed in the transmission cavity, a movable gear is installed in the chute assembly, the curvature of the upper end of the chute assembly is matched with the gear curvature of the first gear, a limiting piece for limiting the lower limit position of the movable gear is installed in the chute assembly, and the end of the chute assembly is the upper limit position of the movable gear. The application is convenient for daily use adjustment, any shutter plate can be separately operated, and the transmission structure is simple.

A biometric identification device based on a surface light source is characterized by comprising: a housing including a light-emitting surface; a sensor located inside the housing for receiving reflected signals from a palm or face; multiple lateral light sources located inside the housing, emitting active light towards a center point; the center point being the center of a shape formed by the multiple lateral light sources; a light guide plate located on the light path of the lateral light sources illuminating the center point, for causing the active light to exit from the side; and a light-diffusing plate located above the light guide plate to ensure uniform emission of the active light. This invention utilizes lateral light sources illuminating along the light guide plate and a light-diffusing plate to ensure uniform emitted light, resulting in a more uniform light path, lower cost, fewer control components, and is beneficial for large-scale applications.
