[0002] A total reflection light emitting lamp comprises a lamp housing, a reflective cup and a lamp arm arranged on the lamp housing, wherein a light source is arranged on the lamp arm and away from the reflective cup, and light emitted by the light source is first emitted to the reflective concave surface of the reflective cup, so that the light is reflected by the reflective concave surface and then emitted outward to illuminate the object.

[0003] In the actual use of the total reflection light-emitting lamp, after the total reflection light-emitting lamp is installed and fixed, the light-emitting direction of the total reflection light-emitting lamp is fixed (that is, the position of the irradiated light spot is fixed). When the position of the object to be illuminated changes, the light emitted by the total reflection light-emitting lamp cannot accurately illuminate the object to be illuminated. In this regard, existing designers will choose to additionally install a rotating mounting seat (the rotating mounting seat includes a seat body and a rotating rod rotatably connected to the seat body, the seat body is used to be installed on a mounting body such as a ceiling, and the rotating rod is used to connect the total reflection light-emitting lamp) to enable the total reflection light-emitting lamp to rotate and adjust the light-emitting direction so that the light can be re-irradiated onto the object to be illuminated.

[0004] However, after market research, the inventors found that: 1. The cost of installing an additional rotating mount is high; 2. After the additional rotating mount is installed, the rotating mount and the total reflection light emitting lamp occupy a large space as a whole, and the user's visual experience is poor.

[0009] According to the above structure, after the installation and fixation of the above-mentioned total reflection light emitting lamp is completed, if the position of the object to be illuminated changes, the user can drive the reflective cup to slide, so that the position of the reflective concave surface relative to the light source changes, to adjust the direction of the light emitted toward the light outlet after reflection by the reflective concave surface, so that the light emitted by the total reflection light emitting lamp can be re-irradiated onto the object to be illuminated after the position is changed. In summary, on the one hand, the above-mentioned total reflection light emitting lamp can adjust the direction of light after installation and fixation, so that the light can be re-irradiated onto the object to be illuminated after the position is changed, thereby adapting to the situation when the position of the object to be illuminated changes; on the other hand, the above-mentioned total reflection light emitting lamp only needs to drive the reflective cup thereon to slide to adjust the direction of light.

When the user rotates the first rotating member 510 by a predetermined angle, the slider member 520 can slide a corresponding distance, that is, the reflective cup 200 can slide a corresponding distance.

[0065] In order to facilitate the user to drive the first rotating member 510 to rotate, refer to Figure 4 and Figure 5 The lamp housing 100 is provided with an avoidance gap S, and the avoidance gap S is located between the side wall of the accommodating cavity 110 and the cup holder assembly 400.
