Description

Technical Field

The existing spotlights are installed in a fixed position, and the light angle cannot be adjusted as required, and cannot adapt to some specific usage scenarios, especially some scenes that require ordinary adjustment of the illumination angle.

[0003] To this end, Chinese patent CN113606524B discloses a spotlight with adjustable light output angle. When the light output angle of the spotlight body needs to be adjusted to achieve the best irradiation angle, the drive assembly is set to work and can be driven by manpower, so that the adjusting member can be driven to rotate around the guide member at a certain angle, and when the adjusting member rotates, the sliding member can be driven to slide on the guide member for a certain distance. Since the sliding member is connected to the corner assembly, the corner assembly can be rotated at a certain angle, and under the self-rotation of the angle adjustment assembly, the corner assembly can be driven to rotate synchronously to achieve the purpose of adjusting the spotlight body, and the spotlight body can be made to perform circular motion to achieve stepless adjustment, which is beneficial to improve the adjustment range of the spotlight body. At the same time, by driving the adjusting member to rotate at an angle, the distance the sliding member slides on the guide member can be changed, thereby changing the amplitude of the rotation of the corner assembly, so as to realize the spotlight body to perform circular motion of different diameters until it is adjusted to the required light output angle, thereby making the spotlight in the best use state and improving the practicality and flexibility of the spotlight.
