Elephant Trunk Lamp

Abstract

A trunk lamp comprises a movable part which is connected to the upper middle portion of a surface ring in a rotating mode. The movable part comprises a heating dissipating lamp body, a conical reflective cover, a light source, a light-transmitting lens and a lamp body surface ring. A light-transmitting lens positioning structure is arranged between the lamp body surface ring and the reflective cover. A lamp body surface ring fixing structure is arranged between the lamp body surface ring and the lamp body. A swing shaft is arranged between the inner side at the lower end of the lamp body and a guide rail ring. An arc-shaped keel is arranged on the back of the lamp body. The arc-shaped surface of the keel is provided with a plurality of positioning parts which are distributed at intervals. The surface ring is provided with projection angle locking structures which are matched with the positioning parts at corresponding positions after the lamp body rotates vertically. According to the trunk lamp, since stepped regulation of a projection angle is realized through the positioning parts arranged on the keel on the back of the lamp body and the projection angle locking structures which are mounted on the surface ring and matched with the positioning parts at the corresponding positions after the lamp body rotates vertically, the projection angle cannot get loose or deflected in the using process of the trunk lamp, and the trunk lamp is more reasonable in structure.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an elephant trunk downlight. Background technique [0002] Elephant Trunk Light is a downlight installed in the ceiling. Its light is projected downward on a vertical surface (such as a wall), and it can be rotated to change the projection angle. It is widely used in hotels, restaurants, shopping malls, offices, exhibition halls, etc. occasion. The lamp body of the current elephant trunk lamp is arc-shaped as a whole, and the outer part is a smooth arc-shaped surface. An arc-shaped bracket is installed outside the arc-shaped surface. An arc-shaped groove, and an angle-adjusting positioning structure that can slide along the arc-shaped groove to adjust the projection angle is installed between the arc-shaped bracket and the arc-shaped surface of the lamp body, as shown in the elephant trunk lamp with Chinese patent number 201220398686.0. Although the angle adjustment and positioning structu...

AI Technical Summary

Problems solved by technology

Although the angle adjustment and positioning structure of the current elephant trunk lamp can realize stepless adjustment of the projection angle, after the elephant trunk lamp has been used for a period of time, the positioning structure will become loose and move, resulting in inaccurate positioning of the projection angle. At this time, the entire lamp needs to be removed from the ceiling to adjust the positioning structure. Therefore, the current elephant trunk lamp with this positioning structure is prone to automatic shifting of the projection angle and requires frequent adjustment and maintenance.
