Description

Technical Field

[0001] This utility model belongs to the field of LED lighting technology, and specifically refers to a multifunctional staircase light. Background Technology

[0002] Staircase lights, a common type of public space and interior decorative lighting equipment, are widely used in stairwell side walls, corridor skirting boards, and step edges. They typically use LED light sources, offering advantages such as low power consumption, long lifespan, and providing safety guidance at night.

[0003] However, traditional step lights have several problems during long-term use. To prevent water damage, step lights typically rely on a ring-shaped seal between the end cap and the lampshade. This large seal is prone to gaps due to aging or temperature changes, leading to corrosion of internal components. Furthermore, because the internal PCB board of a step light is not large, but the seal covers the entire outer perimeter of the lamp body, the sealing structure is excessively large, taking up too much redundant space. Additionally, traditional step lights offer only one color and the lighting effect cannot be adjusted. Utility Model Content
