DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0028] Please refer to Figures 1 to 6 , a lamp with a reflector cup lens, including a reflector cup body 1 in the shape of a hollow cup, and a lens main body 3 arranged on the installation side of the LED lamp group 2 and coaxially arranged with the reflector cup body 1. The LED lamp group 2 includes a light source substrate 21, a main lamp bead 22 arranged in the middle of the light source substrate 21, and auxiliary lamp beads 23 arranged on the light source substrate 21 and surrounding the main lamp bead 22. The lens main body 3 includes a planar structure portion 31, a bowl-shaped structure portion 32 corresponding to the main lamp bead 22, and a cup-shaped structure portion 33 corresponding to the auxiliary lamp beads 23.

[0029] For a lamp with a reflector cup lens in this application, by arranging a lens main body coaxial with the reflector cup body on the installation side of the LED lamp group, and providing a planar structure portion, a bowl-shaped structure portion and a cup-shaped structure portion on the lens main body, corresponding to the main lamp bead and the auxiliary lamp beads respectively, the irradiation path of the light is effectively improved, enabling more light to irradiate onto the inner wall of the reflector cup, reducing the light scattering phenomenon, and improving the light focusing ability. This design not only improves the utilization efficiency of the light source, but also enhances the lighting effect, making the overall light effect more uniform and bright. The lens main body is a Fresnel lens.

[0030] Further, as a preferred implementation manner of this solution rather than a limitation, a light inlet slot hole 34 is formed by enclosing between the planar structure portion 31 and the cup-shaped structure portion 33, and a light inlet opening 35 is formed on the planar structure portion 31 corresponding to the bowl-shaped structure portion 32.

[0031] In this embodiment, the light inlet slot hole 34 can guide the light emitted by the auxiliary lamp beads into the reflector cup body, reducing the light scattering and improving the light efficiency; secondly, the design of the light inlet opening 35 can enable the light emitted by the main lamp bead to enter the bowl-shaped structure portion 32 more effectively, further improving the focusing effect of the light from the main lamp bead. This design can significantly enhance the lighting effect of the entire lamp, making the light more uniform and bright. In addition, the shape and size of the light inlet slot hole 34 can be adjusted according to actual needs. For example, it can be designed as an arc-shaped slot hole with a certain curvature to better guide the light. The shape of the light inlet opening 35 can also be optimized according to the type and light-emitting characteristics of the main lamp bead. For example, it can be designed as a curved surface shape matching the light-emitting surface of the main lamp bead to maximize the collection of the light emitted by the main lamp bead.

[0032] Further, as a preferred implementation manner of this solution rather than a limitation, a plurality of uniformly arranged grid protrusions 331 are provided on the outer surface of the cup-shaped structure portion 33.

[0033] In this embodiment, the grid protrusions 331 can refract and reflect the light emitted by the auxiliary lamp beads, causing the light to be reflected multiple times within the reflector cup body, thereby improving the utilization rate of light and the lighting effect. This design enables the light of the auxiliary lamp beads to be more evenly distributed within the reflector cup body, reducing light scattering and light leakage phenomena, and enhancing the light efficiency and lighting uniformity of the lamp. In addition, the shape, size, and arrangement of the grid protrusions 331 can be adjusted according to actual requirements. For example, protrusions with different heights or angles can be designed to change the refraction path of light; different shapes such as triangles, rectangles, or arcs can also be designed to meet different optical requirements.

[0034] Furthermore, as a preferred implementation manner of this solution rather than a limitation, the area of the grid protrusions 331 gradually increases from the bottom to the top of the cup-shaped structure portion 33.

[0035] In this embodiment, the light emitted by the auxiliary lamp beads gradually diffuses on the outer surface of the cup-shaped structure portion 33, thereby forming a more uniform light intensity distribution within the reflector cup body. Since the area of the grid protrusions 331 at the bottom is smaller, the light is mainly reflected and refracted in the bottom area, while the area of the grid protrusions 331 at the top is larger, enabling the light to gradually spread to a larger area, thus achieving uniform distribution of light.

[0036] Furthermore, as a preferred implementation manner of this solution rather than a limitation, the light inlet slot hole 34 is in a straight cylinder shape.

[0037] In this embodiment, the light emitted by the auxiliary lamp beads can enter the lens main body in a relatively direct manner, reducing direct light during the propagation process, thereby reducing light loss.

[0038] Furthermore, as a preferred implementation manner of this solution rather than a limitation, the light inlet 35 is in a conical shape and the diameter value gradually increases in the direction away from the main lamp bead 22.

[0039] In this embodiment, since the diameter value of the light inlet 35 gradually increases, the light can gradually spread when entering the bowl-shaped structure portion 32, thereby forming a more uniform light intensity distribution within the bowl-shaped structure portion 32. This design can effectively improve the utilization rate of the light of the main lamp bead 22 and the lighting effect, making the light efficiency of the lamp more uniform and bright.

[0040] Furthermore, as a preferred implementation manner of this solution rather than a limitation, the reflector cup body 1 includes a straight cylinder section 11 for accommodating the LED lamp group 2 and the lens main body 3, and a cup section 12 communicating with the top of the straight cylinder section 11.

[0041] In this embodiment, a stable installation space can be provided for the LED lamp group 2 and the lens body 3, enabling them to cooperate better and improving the overall optical performance of the lamp. The straight tube section 11 can provide a flat installation surface for the LED lamp group 2, allowing the light source substrate 21 to be firmly fixed on the reflecting cup body 1; the cup section 12 can reflect and focus the light emitted by the LED lamp group 2, enabling the light to better illuminate the target area. This design can effectively improve the light efficiency and lighting effect of the lamp, making the lamp more energy-efficient and durable.

[0042] Further, as a preferred implementation manner rather than a limitation of this solution, the height of the straight tube section 11 is H, and the distance from the top surface of the lens body 3 to the bottom surface of the light source substrate 21 is S, where H = S.

[0043] In this embodiment, it is ensured that the light can propagate along the optimal path. Since H = S, the top surface of the lens body 3 is flush with the top of the straight tube section 11, enabling the light emitted by the main lamp beads 22 and the auxiliary lamp beads 23 through the lens body to be more fully reflected on the reflecting cup body 1, thereby maximizing the use of the optical effect of the reflecting cup 1.

[0044] The working principle of this embodiment is as follows:

[0045] A lamp with a reflecting cup lens according to the present application, by providing a lens body coaxial with the reflecting cup body on the installation side of the LED lamp group, and providing a planar structure portion, a bowl-shaped structure portion, and a cup-shaped structure portion on the lens body, corresponding to the main lamp beads and the auxiliary lamp beads respectively, effectively improves the irradiation path of the light, enables more light to irradiate on the inner wall of the reflecting cup, reduces the light scattering phenomenon, and improves the light focusing ability. This design not only improves the utilization efficiency of the light source but also enhances the lighting effect, making the overall light efficiency more uniform and bright.

[0046] The above are the implementation manners provided in combination with specific contents, and it is not considered that the specific implementation of the present application is only limited to these descriptions. Any structure similar to the method of the present application, or any technical deduction or replacement made under the premise of the concept of the present application, should be regarded as the protection scope of the present application.
