[0011] The receiving cavity 21 protects the light-emitting element 4 from damage, and the light emitted by the light-emitting element 4 is reflected by the reflection chamber 53 and passes through the transparent section 22 to achieve an illumination effect. The reflector 5 has openings only at both ends, and there are no other openings in the wall of the reflector 5. The reflector 5 can reflect the light emitted by the light-emitting element 4 to direct all light rays through the transparent section 22 for illumination. This allows the lighting lamp 1 to simultaneously prevent light scattering and achieve a focusing effect when emitting light for illumination, thereby increasing the brightness of the illumination in a specific area.

[0012] Specifically, the light-emitting element 4 can be an LED lamp, an incandescent lamp, a fluorescent lamp, a laser diode, etc. Alternatively, the light-emitting element 4 can also be an RGB lamp to generate light beams of different colors.

[0013] In this embodiment, the housing 2 comprises an outer shell 6 and a front ring 7, wherein the outer shell 6 and the front ring 7 are detachably connected by a snap lock. The structure described above allows the outer shell 6 and the front ring 7 to be removed, thus simplifying assembly by the user. Assembly can be performed without additional external tools and requires no further external fasteners, which also saves costs.

[0014] Specifically, a locking groove 73 is formed on the front ring 7 on the side of the receiving cavity 21. The transparent section 22 is inserted into the locking groove 73 and secured to it with adhesive to prevent the transparent section 22 from loosening.

[0015] Of course, in another embodiment the front ring 7 and the outer shell 6 can also be detachably connected by thread or magnetic attraction.

[0016] With reference to Fig. In this embodiment, the front ring 7 has a connecting recess 71 on the end face facing away from the transparent section 22. A connecting through-hole 72 is formed in the side wall of the front ring 7, corresponding to the connecting recess 71. A locking pin 61 is arranged on the outside of the outer shell 6, passing through the connecting through-hole 72 and positioned in the connecting recess 71 to create the connection between the front ring 7 and the outer shell 6. This connection method is simple and can reduce the use of external connecting elements, as it is achieved simply by the locking pin 61 snapping into the connecting through-hole 72.

[0017] Specifically, there are two connecting recesses 71, located on opposite sides of the front ring 7; two locking pins 61, located on opposite sides of the outer shell 6; and two connecting through-holes 72, also located on opposite sides of the front ring 7. The structure described above makes the connection between the front ring 7 and the outer shell 6 more aesthetically pleasing and symmetrical. The double-sided connection ensures a balance of forces at the joint between the front ring 7 and the outer shell 6, thus increasing the stability of the connection. Of course, in other embodiments, the number of locking pins 61 and connecting through-holes 72 can also be three, four, etc.

[0018] Referring to Fig. 3 The lighting lamp 1 further comprises a spring 8, wherein the two ends of the spring 8 each form a first torsion arm 82 and a second torsion arm 83, wherein a limiting opening 84 is formed on the first torsion arm 82, the limiting opening 84 being arranged in the connecting recess 71, and the locking pin 61 being arranged in the limiting opening 84. The force exerted by the spring 8 allows the lighting lamp 1 to be stably attached to the ceiling or to other external mounting openings. This allows the lighting lamp 1 to be installed without external tools, thus simplifying installation. Furthermore, the limiting opening 84 can engage the locking pin 61 inserted into the connecting through-hole 72, making the connection between the locking pin 61 and the connecting through-hole 72 more stable and less prone to loosening. This secures the spring 8 to the outer shell 6.This clever design allows for efficient use of the structure and simplifies product assembly.

[0019] Specifically, two detent springs 8 are provided, located on opposite sides of the outer shell 6. This design increases the contact force of the detent springs 8 on the lighting lamp 1, allowing the lighting lamp 1 to be attached to an external mounting opening without easily falling out.

[0020] Referring to Fig. 2. In this embodiment, the end of the reflector 5 located near the transparent section 22 extends outwards to form a first boundary plate 51, which has a first clearance opening 52 for the connection recess 71 to move away from the transparent section 22. The end of the outer shell 6 located near the transparent section 22 extends outwards to form a second boundary plate 62, which has a second clearance opening 63. The first clearance opening 52 and the second clearance opening 63 are arranged opposite each other. With the structure described above, the first clearance opening 52 and the second clearance opening 63 are used for assembling and releasing the connection recess 71 when the front ring 7 is connected to the outer shell 6.

[0021] In this embodiment, the dimensions of at least part of the cross-section of the reflection chamber gradually taper towards the transparent section facing away from it. The structure described above allows for good light focusing and a uniform illumination effect.

[0022] Referring to Fig. In this embodiment, a positioning groove 31 is provided on the circuit board 3, wherein the reflector 5 is arranged in the positioning groove 31 at the end facing away from the transparent section 22, and the light-emitting element 4 is distributed within the positioning groove 31.

[0023] Referring to Fig. In this embodiment, the inner side wall of the outer shell 6 projects to form a locking section 64. A first locking groove 65 and a third escape opening 66, connected to the first locking groove 65, are formed on the locking section 64. A locking block 67 is arranged at a position on the locking section 64 corresponding to the third escape opening 66. The locking block 67 forms a limiting slot 32 with the inner surface of the outer shell 6. The locking block 67 has a guide surface 671 on a side facing away from the limiting slot 32. This guide surface 671 serves to slide the printed circuit board 3 into the limiting slot 32. The structure described above forms an elastic locking block 67, which, with the aid of the guide surface 671, can slide into the limiting slot 32 during installation of the printed circuit board 3, thus ensuring the secure positioning of the printed circuit board 3.

[0024] Referring to Fig. 1, Fig. 4 and Fig. In this embodiment, the lighting lamp 1 further comprises a switch control section 9, wherein the switch control section 9 includes a switch unit 91 and an actuating section 92 connected to the switch unit 91, the switch unit 91 being mounted on the circuit board 3 and electrically connected to the circuit board 3, the switch unit 91 being opened or closed when the actuating section 92 is actuated.
