Description

Technical Field

[0002] In indoor lighting projects, right-angle lamp holders, as the core installation component of wall-mounted light fixtures, directly impact the electrical safety of users' lives and property. Traditional right-angle lamp holders generally employ an open wiring design, where the connection between the lamp base and the power cord is simply secured with insulating tape. However, during wall decoration or subsequent maintenance, workers may need to paint or sand the walls, and liquid paint (latex paint, putty) can easily splatter onto the connection between the lamp base and the junction box. Due to the lack of effective sealing and isolation in traditional structures, the conductive terminals wrapped with insulating tape are exposed to damp or conductive media for extended periods, easily leading to leakage or even short circuits, especially on walls that are not completely dry. Therefore, achieving full sealing and isolation at the wiring points of right-angle lamp holders to reduce the possibility of electric shock due to liquid paint contact with the lamp base has become a pressing technical problem that needs to be solved.
