The lamp shell 10 has an assembly space 11 and an opening 12 communicating with the assembly space 11. The LED light source 20 is installed in the assembly space 11 and comprises a substrate 21 and an LED chip 22 attached to the substrate 21. The LED chip 22 is used for emitting light and irradiating to the opening 12. The reflector 30 is installed in the assembly space 11 and has a light inlet 31, a light outlet 32 and a reflecting surface 33. The light inlet 31 is arranged opposite to the LED chip 22. In the direction from the light inlet 31 to the light outlet 32, the reflecting surface 33 is cup-shaped with gradually expanding diameter. The reflecting surface 33 is specular reflection. The lenticular lens 40 is installed in the assembly space 11 and covers the light outlet 32. The lenticular lens 40 has an incident surface 41 and an exit surface 42.

[0047] As Figure 6 andFigure 11 As shown in the embodiments of the present application, in the spotlight, along the direction from the light inlet 31 to the light outlet 32, the reflecting surface 33 is set as a curved surface which is convex outward away from the central axis of the reflector 30, so that the reflecting direction of the part of the light emitted by the LED chip 22 which is irradiated to the reflecting surface 33 presents a converging effect towards the central axis of the reflector 30. That is, the light rays reflected by the reflecting surface 33 towards the incident surface 41 of the lenticular lens 40 are convergently collected, thereby achieving the first convergent propagation effect of reflection and collection.

[0048] Further, as shown in the embodiments of the present application, in the spotlight, along the direction from the light inlet 31 to the light outlet 32, the reflecting surface 33 is set as a curved surface which is convex outward away from the central axis of the reflector 30, so that the reflecting direction of the part of the light emitted by the LED chip 22 which is irradiated to the reflecting surface 33 presents a converging effect towards the central axis of the reflector 30.

Figure 11 As shown in the embodiments of the present application, in the spotlight, along the direction from the light inlet 31 to the light outlet 32, the reflecting surface 33 is set as a curved surface which is convex outward away from the central axis of the reflector 30, so that the reflecting direction of the part of the light emitted by the LED chip 22 which is irradiated to the reflecting surface 33 presents a converging effect towards the central axis of the reflector 30.

It is a commonly used glass replacement material and an ideal material for making lenticular lenses 40, and the lenticular lens 40 made of PMMA material is low in cost and durable.

[0051] In a spotlight provided by some embodiments of the present application, the incident surface 41 of the lenticular lens 40 of the spotlight is frosted, and the exit surface 42 is formed with a plurality of spherical cap-shaped protrusions 421, as shown in the embodiments of the present application.

A portion of the light directly irradiated from the LED chip 22 to the double convex lens 40 is incident on the ground surface of the entrance surface 41 together with another portion of the light reflected from the reflective surface 33, and the ground surface of the entrance surface 41 refracts the light to be divergent to the exit surface 42, so that the light can be more uniformly irradiated to the exit surface 42 after being refracted by the entrance surface 41. Moreover, when the light is incident on the plurality of spherical crown protrusions 421, the plurality of spherical crown protrusions 421 converge and mix the light, so that the light refracted by the ground surface of the entrance surface 41 is again converged and mixed through the exit surface 42, thereby emitting uniform light for illumination, improving the uniformity of the light emitted by the spotlight.

[0052] As shown in the embodiments of the present application, Figure 2 , Figures 4 to 6 As shown, in a spotlight provided by some embodiments of the present application, the spotlight further comprises a middle ring 50 and a secondary reflector 60.

Most of the light emitted from the exit surface 42 is directly used for illumination, the beam angle of the emitted illumination light is about 24°, and a part of the scattered light is irradiated to the inner wall of the middle ring 50, and another part of the scattered light is irradiated to the inner wall of the secondary reflector 60. The convex ribs 53 of the middle ring 50 can repeatedly reflect the scattered light irradiated from the exit surface 42 of the double convex lens 40 to the inner wall of the middle ring 50, so as to weaken the scattered light and reduce the influence of the scattered light on the illumination effect. The secondary reflector 60 reflects the scattered light irradiated to the inner wall of the secondary reflector 60, so as to weaken the scattered light and reduce the influence of the scattered light on the illumination effect. Moreover, the inner wall of the middle ring 50 and / or the inner wall of the secondary reflector 60 is black, the black inner wall has a light absorption effect on the scattered light, so as to further reduce the influence of the scattered light on the illumination effect and improve the uniform light emission and illumination effect of the spotlight.

[0053] like Figures 4 to 6 As shown, in some embodiments of this application, a spotlight is provided in which two adjacent protrusions 53 are arranged parallel and spaced apart. This makes it easy to manufacture the protrusions 53 of the central ring 50, simplifying the manufacturing process and reducing manufacturing difficulty.

[0054] like Figures 7 to 9As shown, in another spotlight provided by some embodiments of the present application, the incident surface 41 is shaped with a plurality of spherical cap-shaped protrusions 421, the plurality of spherical cap-shaped protrusions 421 are arranged adjacently, and at least part of the exit surface 42 is provided with a frosted surface. In the spotlight of the present embodiment, the light exit surface of the exit surface 42 is provided with a frosted surface. Further, the spotlight further comprises a middle ring member 50 and a secondary reflector 60, both of which are connected to the lamp housing 10. Specifically, the middle ring member 50 has a plurality of circumferentially spaced connecting columns 54, the connecting columns 54 extend towards the partition plate 13 in the direction from the first port 51 to the second port 52, and the connecting columns 54 are locked on the partition plate 13 by screws, so as to stably install the middle ring member 50, and the end wall of the light inlet 31 abuts against the base plate 21. The secondary reflector 60 is connected to the lamp housing 10 through an adapter sleeve 72, that is, the adapter sleeve 72 is sleeved on the secondary reflector 60, and the secondary reflector 60 is snap-connected with the adapter sleeve 72, and the adapter sleeve 72 is locked on the lamp housing 10 by screws. The first port 51 of the middle ring member 50 is butted against the light exit port 32, the circumferential edge of the double-convex lens 40 is clamped and fixed between the end wall of the light exit port 32 and the end wall of the first port 51, the circumferential edge of the double-convex lens 40 is clamped and fixed between the end wall of the light exit port 32 and the end wall of the secondary reflector 60, one end of the secondary reflector 60 extends into the middle ring member 50 through the second port 52 of the middle ring member 50, and the end port of the secondary reflector 60 faces the exit surface 42, the other end of the secondary reflector 60 extends out of the opening 12, the secondary reflector 60 is trumpet-shaped, and the inner wall of the secondary reflector 60 is provided with a silver or silver-gray color. When the spotlight is in use, the light reflected from the reflecting surface 33 and the part of the light emitted by the LED chip 22 that is directly incident on the double-convex lens 40 together enter the incident surface 41 provided with the plurality of spherical cap-shaped protrusions 421, the plurality of spherical cap-shaped protrusions 421 converge and mix the light, and then the light continues to illuminate the exit surface 42 provided with a frosted surface, the frosted surface refracts and disperses the light, so that the light is refracted and dispersed by the double-convex lens 40 to converge and mix the light, so as to emit uniform light for illumination. Further, since the light is refracted and dispersed by the exit surface 42 provided with a frosted surface, the beam angle of the exit illumination light is about 50°, and a larger range of spotlight illumination effect is achieved. Further, the inner wall of the secondary reflector 60 is provided with a mirror silver color, a mirror black color, or a mirror gun-gray color. A part of the exit light is scattered towards the inner wall of the secondary reflector 60, when the inner wall of the secondary reflector 60 is provided with a mirror silver color, the scattered light can be reflected again to mix and exit, so as to reuse the scattered light for illumination, and improve the light utilization efficiency.

[0055] Further, in another spotlight provided by some embodiments of the present application, as shown in Figure 10As shown, the emitting surface 42 of the spotlight also has an annular region 422. The surface of the annular region 422 is frosted, and the other surfaces of the emitting surface 42, except for the annular region 422, are polished. In this spotlight, the beam angle of the emitted illumination light is also approximately 50°. Therefore, the annular region 422 of the biconvex lens 40 refracts and disperses the light before it is emitted, and the light from other parts is mixed evenly by multiple spherical protrusions 421 before being emitted from the other polished surfaces of the emitting surface 42. This results in uniform overall brightness of the emitted light from the emitting surface 42. Even if the human eye looks directly at the light emitted by the spotlight, it can reduce or even eliminate discomfort such as glare and stinging, thus improving the user experience.

[0056] like Figures 1 to 10 As shown, the spotlight in this embodiment of the application also includes a housing 73, which is sleeved on the adapter sleeve 72, and the housing 73 and the adapter sleeve 72 are stably connected by a snap-fit. The housing 73 also has a mounting position for installing a retaining spring. When the spotlight needs to be installed in a pre-drilled mounting hole on the ceiling or wall, the retaining spring is first installed in the mounting position on the housing 73, then the retaining spring is compressed, the spotlight is placed into the pre-drilled mounting hole, and the retaining spring is released. Thus, under the elastic force of the retaining spring, the entire spotlight is stably installed in the pre-drilled mounting hole.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
