Description

[0002] With the rapid development of road infrastructure, the demand for road lighting is becoming more and more extensive. Street lamps have become an indispensable part of road lighting, and street lamp components are one of the important components of street lamps. Street lamp components are composed of light sources, lens modules, heat dissipation structures and other components. The main function of the lens module is to converge or diverge the light emitted by the light source to achieve the expected optical effect and meet the needs of road lighting.
[0003] In the prior art, reference Figure 1 The multiple lenses 11 on the lens module are usually of the same size. The street lamp assembly includes multiple light sources 12 with the same light-emitting area. The multiple lenses 11 and the multiple light sources 12 are matched and arranged one by one.
[0004] However, since each lens on the lens module is the same size, each lens can only match a light source with a corresponding luminous area. Therefore, when the number of lenses is the same, the luminous area of the light source used by the lens module is the number of single lenses multiplied by the luminous area of the light source used by each lens. The luminous area of the light source used by the lens module is limited, which limits the spatial utilization of the light source by the lens module. Within the limited lens module space, more luminous area of the light source cannot be utilized, which to a certain extent limits the parameter performance of the street lamp module.

[0030] like Figures 2 to 6 As shown, a heterogeneous birefringent lens module includes a substrate 2, on which are disposed a plurality of first lenses 3 and a plurality of second lenses 4, a first cavity 31 is disposed at the lower side of the first lens 3, a second cavity 41 is disposed at the lower side of the second lens 4, the space of the second cavity 41 is larger than the space of the first cavity 31, the first cavity 31 can accommodate a first light source assembly 5, and the second cavity 41 can accommodate a second light source assembly 6 having a larger light-emitting area than the first light source assembly 5.
[0031] The heterogeneous birefringent lens module includes a plurality of first lenses 3 and a plurality of second lenses 4. The sizes of the first lenses 3 and the second lenses 4 are different. The first cavity 31 of the first lens 3 can accommodate a first light source assembly 5 with a smaller light-emitting area. The first lens 3 can refract the light of the first light source assembly 5. The second cavity 41 of the second lens 4 can accommodate a second light source assembly 6 with a larger light-emitting area. The second lens 4 can refract the light of the second light source assembly 6. The second light source assembly 6 with a larger light-emitting area is inside the second lens 4 with a larger size, that is, the area of the substrate 2 occupied by the lens is reduced under the same light-emitting area. Under the same substrate 2 area, a larger light-emitting area can be obtained, thereby improving the space utilization rate of the lens module for the light source, which is beneficial to improving the parameter performance of the street lamp assembly.
[0032] The following compares the light-emitting areas of the prior art and the present solution using substrates of the same size.
[0033] like Figure 1 As shown, the existing lens module is basically covered with 30 lenses, each lens is the same size, each lens is corresponding to a light source, and the light-emitting area of the light source is 1 light-emitting unit area. The existing lens module has 30 light-emitting unit areas.
[0034] like Figure 4 As shown, the heterogeneous birefringent lens module of this embodiment is also basically covered with 30 lenses, but the 30 lenses include 14 first lenses 3 and 16 second lenses 4. The first lenses 3 are the same size as the lenses in the above-mentioned existing lens module, and the size of the second lenses 4 is larger than the size of the first lenses 3. Each first lens 3 is provided with a light source, and the light source is the same as the above-mentioned Figure 1 The light sources in the embodiment are the same size, and each second lens 4 is correspondingly provided with two light sources, then the heterogeneous birefringent lens module of this embodiment has 46 light emitting unit areas, which is much larger than the 30 light emitting unit areas of the above-mentioned existing lens module. In this embodiment, the second lens 4 can match two light sources, while the existing lens module requires two lenses to match two light sources, and the size of one second lens 4 is larger than the size of two lenses, that is, the substrate area occupied by the lens is reduced under the same size of light emitting area, so on the substrate of the same size, this embodiment can be provided with more light sources than the existing technology, and this solution can obtain a larger light emitting area, thereby improving the space utilization rate of the lens module for the light source.
[0035] In some specific embodiments, with the length direction of the substrate 2 as the first direction and the width direction of the substrate 2 as the second direction, the length of the second lens 4 in the first direction is greater than the length in the second direction, and the length of the second lens 4 in the first direction is greater than the length of the first lens 3 in the first direction.
[0036] Further, the length of the second lens 4 in the second direction is equal to the length of the first lens 3 in the second direction.
[0037] In some specific embodiments, at least some of the first lenses 3 are arranged in sequence along the first direction and located in the middle of the substrate 2, and a plurality of first lenses 3 arranged in sequence along the first direction and located in the middle of the substrate 2 form a first lens group, and a plurality of second lenses 4 are respectively located on both sides of the first lens group in the second direction.
[0038] In some specific embodiments, the number of first lenses 3 is 14, the number of second lenses 4 is 16, the first lens group includes 8 first lenses 3, 8 second lenses 4 are arranged in sequence along the first direction and are located on one side of the first lens group in the second direction, 8 second lenses 4 are arranged in sequence along the first direction and are located on the other side of the first lens group in the second direction, 3 first lenses 3 are arranged in sequence along the second direction and are located on one side of the first lens group in the first direction, and 3 first lenses 3 are arranged in sequence along the second direction and are located on the other side of the first lens group in the first direction. In other embodiments, different numbers of first lenses 3 and second lenses 4 can be set according to the size of the substrate 2, light parameters, etc., and the arrangement of the first lenses 3 and second lenses 4 can also adopt different arrangement methods according to actual needs.
[0039] In some specific embodiments, both the incident surface and the exit surface of the first lens 3 are smooth curved surfaces, and both the incident surface and the exit surface of the second lens 4 are smooth curved surfaces. Compared with the arrangement of a beaded surface structure, or a structure of a non-continuous complex shape such as a strip shape or a tooth shape on the curved surface, the arrangement of a smooth curved surface in this embodiment can reduce the manufacturing cost and design complexity of the heterogeneous birefringent lens module.
[0040] In some specific embodiments, the substrate 2, the first lens 3 and the second lens 4 are integrally formed, which can make production more efficient and reduce production costs.
[0041] In some specific embodiments, the material of the heterogeneous birefringent lens module is polycarbonate. Polycarbonate, i.e., PC material, has good light transmittance and weather resistance. In other embodiments, the heterogeneous birefringent lens module can also be made of other commonly used lens materials.
[0042] On the other hand, a street lamp assembly having the above-mentioned heterogeneous birefringent lens module further includes a first light source assembly 5 and a second light source assembly 6, wherein the light emitting area of the second light source assembly 6 is larger than the light emitting area of the first light source assembly 5, the first light source assembly 5 is disposed in the first cavity 31, and the second light source assembly 6 is disposed in the second cavity 41.
[0043] By adopting the above-mentioned heterogeneous birefringent lens module, the space utilization rate of the light source can be improved, which is beneficial to improving the parameter performance of the street lamp component.
[0044] In some specific embodiments, referring to Figure 5 and Figure 6 The first light source assembly 5 includes a light source element 61, and the second light source assembly 6 includes two light source elements 61. The light source element 61 can be a lamp bead. The same light source element 61 can reduce the production material model and simplify the production process.
[0045] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
