The utility model discloses a kind of curtain wall decorative lamps, including lamp shell, light source board, lampshade and adjusting mounting seat, light source cavity inside lamp shell is equipped with asymmetric light-reflecting inclined plane A and light-reflecting inclined plane B, cooperate with the light mixing inclined plane in lampshade, light efficient mixing and uniform light emission are realized jointly, effectively eliminate glare and mottle, light source board adopts double-row lamp pearl of staggered arrangement, each lamp pearl is equipped with flexible convex cover, further eliminate stray light, lamp body bottom connects multiple groups of anti-falling rope, guarantee high-altitude safety, its core is adjusting mounting seat adopts worm gear drive mechanism, by rotating knob, stepless fine adjustment of the pitch angle of lamp body can be realized, and using its inherent self-locking characteristic, ensure that angle adjustment is long-term stable after, windproof and anti-vibration, solve the difficult problem that traditional curtain wall lamp adjustment is complicated, easy to deviate.

This utility model discloses a light guide strip and a device with a light guide strip. The light guide strip includes a light guide strip body, which is a rigid structure. The bottom surface of the light guide strip body has a light-incident area, and the top surface has a light-exiting area. The light-incident area and the light-exiting area are connected by a reflective area. A refractive groove is located in the light-incident area and is used to correspond to an LED light. Multiple refractive grooves are spaced apart along the extension direction of the light-incident area. The device with the light guide strip includes a housing, an LED light, and the aforementioned light guide strip. The LED light and the light guide strip are located inside the housing. The refractive grooves correspond to the LED light. The housing has a light-exiting part, and the light-exiting area corresponds to the light-exiting part. The light guide strip is characterized by its small thickness, small space occupation, and combination of optical performance and mechanical strength. It can be widely used in various devices, has good heat dissipation and light emission effects, is easy to use for long-term use, and is low in cost.
