Referring to Figure 3 , it is shown that the reflector cup 4 is arranged directly below the lamp bead 2, referring to Figure 4 , it is shown that the reflector cup 4 can be moved to be eccentric to the lamp bead 2, so that when it is necessary to adjust the position of the light spot, it is only necessary to apply force to the reflector cup seat 3 to overcome the magnetic attraction between the magnet 5 and the metal plate 6, so that the light spot adjustment becomes simpler and more convenient, compared with the prior art, the reflector cup moving structure is greatly simplified, the number of parts is reduced, the manufacturing cost of the lamp is reduced, and the product has good market competitiveness.

[0036] In some embodiments of the present application, referring to Figure 6 and Figure 7 , a plurality of balls 8 are arranged at the bottom of the reflector cup seat 3, the balls 8 are rollable on the metal plate 6, the bottom end surface of the magnet 5 is higher than the bottom of the balls 8, so that the magnet 5 and the metal plate 6 are not in contact, specifically, the magnet 5 and the metal plate 6 are close to each other without being in contact, the distance between the bottom end surface of the magnet 5 and the metal plate 6 is very small, but there is no direct contact, which not only ensures the magnetic attraction between the magnet 5 and the metal plate 6, but also avoids the sliding friction between the magnet 5 and the metal plate 6 when the reflector cup seat 3 is moved, and the rolling friction is realized by using the balls 8, so that the movement of the reflector cup seat 3 on the metal plate 6 becomes easy, and the light spot adjustment becomes simple and easy to operate.

[0037] Referring to Figure 5 As shown in the drawings, in some embodiments of the present application, the metal plate 6 is a circular plate, and the side wall of the metal plate 6 is close to or in contact with the cavity wall of the cavity. In this way, the space in the cavity of the shell 1 can be fully utilized, so that the metal plate 6 can be designed larger to provide more space for the magnet 5 on the metal plate 6, thereby improving the range of spot position adjustment.

The lamp arm 11 is generally made of aluminum, and the thermal conductivity of aluminum is poor. When the lamp bead 2 emits light, a large amount of heat will be generated. Only relying on the heat conduction of the lamp arm 11 and air cooling is not enough to quickly dissipate the heat of the lamp bead, which will affect the service life of the lamp bead 2. The thermal conductivity of the copper plate 7 is much higher than that of aluminum, and the copper plate 7 can quickly conduct heat away.

[0040] Referring to Figure 5 As shown in the drawings, in some embodiments of the present application, the shell 1 includes a heat sink 13 and a base 14 located below the heat sink 13. The copper plate 7 extends from the cantilever end of the lamp arm 11 to the side wall of the heat sink 13, and the copper plate 7 is L-shaped. In this way, the heat dissipation is further improved, and the copper plate 7 is integrally die-cast with the heat sink 13.

[0041] Referring to Figure 1 , Figure 2 and Figure 5 As shown in the drawings, in some embodiments of the present application, an air duct 15 is formed between the heat sink 13 and the base 14, and the air duct 15 is in communication with the cavity, so that the heat in the cavity can be quickly dissipated.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application.
