[0046] According to the embodiments of the present utility model, by setting like this, at least the following effects can be achieved. The adjustment mechanism of the downlight realizes the free rotation of the lamp body in the housing 100 through the rotation end 200 on the housing 100, in cooperation with the precise fit of the rotation block 110 and the rotation groove 210. This design enables the downlight to flexibly adjust the incident angle of the light and easily direct the light to different required positions; the adjustment system of the downlight also includes a delicate striker 300 mechanism, which is driven by elastic force and can automatically move towards the card slot 111, thereby realizing the precise adjustment of the angle of the downlight. When the rotation end 200 rotates to a specific position, the striker 300 will contact the side wall of the card slot 111 and contract under the action of an external force, allowing the rotation end 200 to be further adjusted to a new angle; more ingeniously, when the striker 300 collides with the card slot 111, a clear sound feedback will be generated, which not only provides an intuitive signal for the user's operation but also ensures that the adjustment of the rotation end 200 is in place. This design not only improves the convenience of use of the downlight but also increases its adjustment accuracy and reliability.
