The present disclosure relates to a technical filed of lighting, and particularly relates to a lens and a light source module.
With the improvement of people's living standard, lighting devices have become an indispensable electrical appliance in people's daily life, which can provide lighting for the environment. In order to improve the lighting effect, lenses are widely used in the current lighting devices to distribute light for light emitting units.
The examples of the present disclosure provide a lens and a light source module.
In the first aspect, the examples of the present disclosure provide a lens. The lens may include a suction portion and at least two light distribution portions.
Each of the light distribution portions may be configured to distribute light for a light emitting unit independently, and a plurality of light distribution portions may be arranged around the suction portion with the suction portion as a center and are fixedly connected with the suction portion.
Each of the light distribution portions may be provided with a light source cavity, a bonding surface and a light exiting surface, and the bonding surface and the light exiting surface face may be away from each other, the light source cavity may be a recess recessed in a direction from the bonding surface to the light exiting surface, the suction portion may be provided with a suction surface, and the light exiting surface and the suction surface face may be toward a same direction.
In the second aspect, the examples of the present disclosure provide a light source module. The light source module may include a light source board, light emitting units and the lens as described above, the light emitting units may be arranged on the light source board in groups, and the light emitting units in each group are in one-to-one correspondence with the light distribution portions in one lens, and the bonding surfaces may be attached to the light source board and the light emitting units in a same group may be respectively placed in different light source cavities.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.
The accompanying drawings described herein are intended to provide a further understanding of the present disclosure, and constitute a part of the present disclosure, illustrative examples of the present disclosure and together with the description serve to explain the present disclosure, and constitute no undue limitation to the present disclosure. In the accompanying drawings:
In order to make objectives, technical details and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be described in a clearly and fully understandable way in connection with the examples and the corresponding drawings of the present disclosure. Apparently, the described examples are just a part but not all of the examples of the present disclosure. Based on the examples in the present disclosure, those skilled in the art can obtain other example(s), without any inventive work, which should be within the protection scope of the present disclosure.
Description of numerals in this disclosure may include:
1—lens, 10—light distribution portion, 100—light source cavity, 101—light incident surface, 102—bonding surface, 103—light exiting surface, 104—base, 105—light distribution cover; 106—connection edge, 11—suction portion, 110—suction surface, 12—positioning element, 13—adhesive receiving groove, 2—light emitting unit, 3—light source board.
Sometimes, there are two types of lenses being used, the first type is to equip each light emitting unit with a lens separately, and the second type is to equip a row or a circle of light emitting units with a stretching lens. These two lens types have different light distribution effects, which can be selected according to needs.
For the lens of the first type, it is usually sucked by a suction nozzle and attached to the surface of a light source board during assembly. The number of lenses in a light source module usually ranges from dozens to hundreds, and each lens needs to be sucked independently, which takes a lot of time.
The example of the present disclosure discloses a lens 1, which includes at least two light distribution portions 10 and a suction portion 11, as shown in
The suction portion 11 is provided with a suction surface 110 configured to be sucked by a suction nozzle. A plurality of light distribution portions 10 are arranged around the suction portion 11 with the suction portion 11 as a center, and all of the light distribution portions 10 are fixedly connected with the suction portion 11. The suction surface 110 has the same orientation as the light exiting surface 103 of the light distribution portion 10.
As shown in
In this way, the light distribution structure of a group of light emitting units 2 can be assembled at the same time in one suction and attachment process, so that the assembly time of the lenses can be greatly saved. In the present example, the arrangement and number of the light distribution portions 10 can be adjusted according to the suction weight of the suction nozzle and the distribution of the light emitting units. The weight of a single lens 1 should not exceed the maximum weight that the suction nozzle can suck. Generally, the number of light distribution portions 10 in one lens 1 is about 2 to 3, or it can be expanded to more than 3, and a suction nozzle with higher power or suction force can be used.
In the case where the lens 1 includes two light distribution portions 10, the two light distribution portions 10 are basically symmetrically arranged on both sides of the suction portion 11 (see
The whole lens 1 has a thickness direction. The light distribution portion 10 includes a base 104 and a light distribution cover 105. The light distribution cover 105 is arranged on the base 104 along the thickness direction. In this case, the bonding surface 102 is a surface of the base 104 facing away from the light distribution cover 105, and the light exiting surface 103 is the outer surface of the light distribution cover 105. The light source cavity 100 usually passes through the base 104 from the bonding surface 102 to inner side of the light distribution cover 105. Because the light exiting surface 103 is used for light distribution, it has a predetermined surface shape, and a connection edge 106 is formed between the light exiting surface 103 and the base 104 as a boundary. The suction portion 11 is fixedly connected with the base 104, and the suction surface 110 should not exceed the connection edge 106 in the thickness direction, so that the suction portion 11 will not block the light emitted from the light exiting surface 103, and thus will not affect the light emitting effect.
Because the suction nozzles in the related art have been able to suck various surface shapes, the suction surface 110 in the present example can adopt various surface shapes suitable for suction. However, considering the convenience of manufacturing and suction stability, the suction surface 110 is preferably a planar surface. Moreover, the suction surface 110 can be flush with the connection edge 106 to further reduce the manufacturing difficulty. On this basis, in the present example, the suction portion 11 can keep the same thickness as the base 104, so that the suction portion 11 can keep flush with the bonding surface 102, thus increasing the bonding area between the lens 1 and the light source board 3, and improving the assembly stability.
In the present example, the light distribution portions 10 in the lens 1 can have the same surface shape and the same light distribution effect, or can have different surface shapes and different light distribution effects. For example, the light emitting units 2 in each group can have different color temperatures. In this case, different surface shapes can be adopted for the light distribution portions 10, so that the light distribution portions 10 of the lens 1 can form an overall composite light distribution effect.
Therefore, the assembly accuracy of the lens 1 and the light source board 3 is also very important. In the present example, in order to improve the assembly accuracy of the lens 1 and the light source board 3, positioning elements 12 can be arranged on the lens 1, and the positioning elements 12 are arranged on the bonding surfaces 102 of a plurality of bases 104 to fully disperse and improve the positioning effect. The positioning element 12 can be a positioning structure, such as a positioning groove (see
