This application belongs to the field of lighting technology and discloses an eye-protecting desk lamp based on a dual-light source simulating the solar spectrum. The lamp includes a housing assembly comprising a base, a column, and lamp heads. The bottom end of the column is rotatably connected to the top center of the base. Two lamp heads are provided, each symmetrically and movably connected to the top two sides of the column via adjusting connectors, allowing the lamp heads to rotate bidirectionally along both the longitudinal and transverse axes. Each lamp head has a first light source cavity and a second light source cavity at its bottom. An LED light panel is fixedly installed in the first light source cavity, and a modified halogen lamp is detachably and fixedly connected to the second light source cavity. This application, by combining LED and xenon-aluminum lamps as light sources, leverages the advantages of both to obtain a continuous high-energy spectrum from blue light to red light and all the way to near-infrared, which is closer to the natural solar spectrum, providing a more comfortable visual experience, better color rendering, and is more beneficial to the visual health of teenagers.

According to the technical scheme, the automobile dimming skylight is characterized by comprising first glass, a dimming film, a light-emitting film and second glass which are arranged from top to bottom, and adhesive films are arranged between the first glass and the dimming film, between the dimming film and the light-emitting film and between the light-emitting film and the second glass. According to the utility model, the phenomenon that the dark-state reflection of the dimming glass is strong to influence the vision when the external light is dark and the internal light is bright is effectively solved, so that the vision of a driver and passengers in a vehicle is comfortable, and the hidden dangers of privacy, safety and the like can be eliminated.

The utility model relates to the field of intelligent education, in particular to a spliced multimedia intelligent blackboard which comprises a box body, the box body is used for supporting and protecting an internal structure, a first bolt and a second bolt are arranged in the box body, and the first bolt and the second bolt are symmetrically distributed above a movable plate with the movable plate as a symmetry axis; and the transmission assembly is mounted in the box body. The driving hydraulic cylinder drives the spur rack to move so as to drive the spur gear and the third movable rod to rotate, meanwhile, the first movable rod and the second movable rod are driven to rotate, the spur rack stably moves through the sliding groove, the second intelligent blackboard body is opened, and a viewer can view the first intelligent blackboard body and the second intelligent blackboard body; an original small screen is changed into a large screen for display, so that the visual sense of a viewer is more comfortable, the teaching requirement can be better met, the teaching effect is improved, and the intelligent blackboard body II and the intelligent blackboard body I can be supplemented by writing on the surface of the box body.
