Abstract

The invention relates to a lighting device which comprises a lighting lamp body assembly and an optical lens assembly, the lighting lamp body assembly is electrically connected with the optical lens assembly, the optical lens assembly comprises an optical lens, a sliding rail disc and a limiting seat, and the optical lens is rotationally connected with the sliding rail disc. The limiting seat is arranged between the optical lens and the sliding rail disc, the sliding rail disc rotates to drive the optical lens to move in the direction away from or close to the sliding rail disc, and the limiting seat limits the moving distance of the optical lens relative to the sliding rail disc. The optical lens can change the angle of the light beam so as to adapt to the requirements of different light beam angles. According to the lighting device, the work of a plurality of lighting devices with different light beam angles can be completed through one lighting device, multiple purposes are achieved through one machine, the use cost is reduced, and the utilization rate of the lighting device is increased.

Description

【Technical field】

[0001] The invention belongs to the technical field of lighting devices, in particular to a lighting device. 【Background technique】

[0002] In some scenes with insufficient light, a lighting device is needed to illuminate the environment, and at this time, it is necessary to select a lighting device with a suitable beam angle according to the environment. The beam angle of the existing lighting device is single, and the angle of the beam is usually a fixed angle that cannot be adjusted, which makes it necessary to prepare multiple lighting devices when in use, for example, select lighting devices with various beam angles according to the environment during use To meet the needs of the scene, this will require users to make a detailed assessment of the environment and lighting devices in the early stage of use, which will greatly increase manpower and material resources and increase costs. 【Content of invention】

[0003] In order to overcome the problems...
