Lamp

Abstract

A lamp comprises a support provided with two oppositely arranged connecting parts, two end covers, two limiting gaskets fixedly arranged on the connecting parts respectively, two rotary gaskets rotating together with the end covers, two spring washers, and two fasteners sequentially penetrating through the components mentioned above respectively, wherein each end cover is provided with an internal thread matched with the corresponding fastener, an accommodating cavity is formed in each end cover in the axial direction of the corresponding fastener, the spring washers are arranged in the accommodating cavities respectively in a sliding mode and are in point contact with the rotary gaskets to prevent the fasteners from being locked, the rotary gaskets are fixedly arranged in the accommodating cavities, each rotary gasket is provided with a protruding limiting part, and each limiting gasket is provided with at least one limiting groove matched with the corresponding protruding limiting part. According to the lamp, fastening nuts matched with the fasteners are not needed, and external installation of the lamp is facilitated; meanwhile, rotation within a certain angle range is achieved through matching between the protruding limiting parts of the rotary gaskets and the limiting grooves of the limiting gaskets.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lamp with a rotation limiting function. Background technique [0002] Compared with traditional lighting fixtures, LED lamps have the advantages of low energy consumption and high luminous efficiency, so LED lamps can be rapidly popularized and applied. In order to adjust the lighting range, it is generally necessary to use a rotating mechanism to meet the requirements of different lighting areas. Lamps in the prior art generally use gaskets or coil springs interposed between the fastener and the fastening nut to prevent the fastener from being locked. Generally, the fastener is screwed outside the lamp, and the fastening nut that matches the fastener is tightened inside the lamp. After the fastener and the fastening nut are installed, the installation assembly will be installed on other lamp structures. On the other hand, it makes the installation process more cumbersome and inconvenient...

AI Technical Summary

Problems solved by technology

However, the lamps in the prior art generally limit the rotation range of the lamp body through the lamp body being blocked by the lamp frame or the lamp body being blocked by walls, cabinets, etc. in the installation environment.

Therefore, this type of luminaire requires a corresponding structurally designed installation environment or lamp holder to cooperate to achieve rotation limit, which limits the application range and free design space of the luminaire.

In the prior art, there are also lamps that use other limiting mechanisms located at both ends of the lamp to realize the rotation limit of the lamp, but such a limiting mechanism has a complex structure and does not have the overall concise and beautiful effect
