Background

Lighting is one of the most common technologies in the mature and human life, from the first halogen bulbs to the later fluorescent lamps and the now popular LEDs and even laser lamps, all being specific applications of lighting technology. The prior light-emitting device is mostly in a relatively fixed state after being installed no matter what light source is adopted, and especially the strip-shaped light-emitting device is difficult to change the irradiation angle conveniently.

In order to solve the technical problem, the prior art generally adopts a mounting structure of a mobile light-emitting device to realize the change of the illumination angle, for example, the light-emitting device is mounted on a metal hose, and the change of the illumination angle is indirectly realized through the bending and the rotation of the metal hose; if the light-emitting device is arranged on the lamp holder, the irradiation angle of the light-emitting device is changed through the rotating structure of the lamp holder.
