Technical Field

[0001] The utility model belongs to the technical field of downlights, and particularly relates to a downlight with high light efficiency. Background Art

[0002] Downlights are a type of recessed lamp that is usually installed inside the ceiling, with only the lampshade exposed, creating a simple, modern lighting effect. Downlights are widely used in various indoor spaces such as homes, offices, shops, and restaurants.

[0003] Existing high-efficiency downlights are installed inside the ceiling through a bracket, so that the light-emitting module in the downlight transmits light through the lampshade to illuminate the space that needs to be illuminated. However, in actual use, since the angle of the downlight is mostly fixed when it is installed, most of the time it irradiates straight from top to bottom, so that the downlight can illuminate the appropriate position required during use. When the irradiation position needs to be adjusted, the light-emitting module in the downlight is driven to adjust the angle by controlling the electronic control module. However, due to structural limitations, the range of irradiation angle adjustment is limited, and the control of the adjustment of the irradiation position of the downlight is limited. Utility Model Content
