In this embodiment, the track box, light arm, heat sink, and light source plate are all conventional structures of the prior art, simply applied in a simplified manner. The light body and heat sink are both aluminum structures. The light source plate is a COB light source.

[0028] Furthermore, the lamp cavity is a frustum-shaped cavity with a small inner diameter and a large outer diameter; through the above structure, the illumination range can be improved.

[0029] In practical applications, several C-shaped protrusions 7 are integrally formed on the inner wall of the lamp cavity; and a reflector cup 8 is provided inside the lamp cavity, with a mounting ring 9 on the outside of the reflector cup. An L-shaped snap-fit ​​block 10 is integrally formed on the outer wall of the mounting ring, and snap-fit ​​protrusions 11 are provided on the transverse outer wall of the L-shaped snap-fit ​​block; the mounting ring is a plastic structure. This allows for a certain degree of deformation. During processing, the size of the mounting ring matches the inner diameter of the lamp cavity opening, so that when inserted, it can be positioned by engaging with the recessed area of ​​the C-shaped protrusions through the snap-fit ​​protrusions. During installation, the reflector cup and mounting ring are located inside the lamp cavity, and the snap-fit ​​protrusions of the L-shaped snap-fit ​​block rotate and engage with the recessed area of ​​the C-shaped protrusions for positioning. The light from the light source plate is emitted outward through the reflector cup. In this embodiment, there are three C-shaped protrusions, and the number of L-shaped buckles matches the number of C-shaped protrusions. During installation, the L-shaped buckles are inserted between adjacent C-shaped protrusions and rotated to position the buckle protrusions into the recessed areas of the C-shaped protrusions.

[0030] In this embodiment, the outer wall of the reflector end is integrally formed with a locking protrusion 12; the inner wall of the mounting ring is provided with a locking ring groove; the locking ring groove is not shown, but it is mainly used to engage the locking protrusion to position the reflector. During assembly, the end of the reflector is located inside the mounting ring, and the locking protrusion is engaged in the locking ring groove for positioning. This structure also facilitates the disassembly, assembly, and maintenance of the reflector and mounting ring.

[0031] In this embodiment, reflective protrusions 13 are uniformly arranged on the inner wall of the reflector cup; the light from the edge of the light source plate is reflected outward through the reflective protrusions. This structure improves the effectiveness and stability of the reflection, and the shape of the reflector cup matches the shape of the lamp cavity.

[0032] This utility model has positive effects: The structure of this utility model is reasonable. It has a reflector cup set in the lamp cavity and the reflector cup is installed and positioned in the lamp cavity by the mounting ring. Since the number of lenses is reduced, it is beneficial to improve the assembly efficiency. When in use, the light from the light source board shines outward and the light from the edge of the light source board shines outward after being reflected by the reflector cup, which is beneficial to improve the lighting decoration effect, improve the convenience and effectiveness of disassembly and assembly, and has strong applicability.

[0033] Furthermore, its reflector cup and mounting ring are connected by snap-fit, which makes it easy to disassemble and maintain. At the same time, there are reflective protrusions on the inner wall of the reflector cup, which also helps to improve the edge light reflection effect of the light source board, making it highly versatile.
