Description

Technical Field

[0001] The utility model relates to a lighting fixture, in particular to a spotlight. Background Art

[0002] The current embedded spotlights are generally composed of two parts: the lamp body and the embedded box. The embedded box is pre-buried in the roof during the decoration construction, and the lamp body is installed in the embedded box after wiring. The existing methods of installing and fixing the embedded box and the lamp body are roughly as follows:

[0003] The first one is that the lamp body and the embedded box are fixedly connected by screws. This assembly method has a relatively simple structure, but the screw heads are exposed and easily rusted, affecting the aesthetics of the product.

[0004] The second type is to set a snap-fit ​​or rebound self-locking structure between the lamp body and the embedded box to achieve fixation, such as an embedded installation structure disclosed by announcement number CN208998017U, an LED downlight embedded part disclosed by announcement number CN206369195U, etc. The spotlight of this structure needs to set a snap-fit ​​or rebound self-locking structure between the lamp body and the embedded box, which makes the structure of the product more complicated.

[0005] The third method is to fix the lamp body and the embedded box by magnetic attraction. However, since the lamp body and the embedded box are generally made of non-ferromagnetic materials such as aluminum alloy, it is necessary to set permanent magnets and iron sheets between the two to achieve fixation. In addition, the magnetic fixation is easily fallen off due to vibration, and the safety is not high.

[0006] In addition, the existing embedded spotlights with multiple lamp heads are fixed on a connecting plate, and the adjustment direction is achieved by adjusting the angle of the connecting plate. The direction of each lamp head cannot be adjusted independently, which brings inconvenience to users in dimming. Utility Model Content
