Description

Technical Field

[0001] This utility model belongs to the field of LED lens mold technology, and relates to a D-level light distribution motorcycle headlight LED lens module. Background Technology

[0002] In order to facilitate night driving, existing motorcycles are equipped with headlights on the front of the vehicle. The installation standard requires that the headlights have both high beam and low beam functions. The headlights used in existing motorcycles generally consist of a lamp housing, a lens at the front of the lamp housing, and an internal lighting structure composed of LEDs and reflectors.

[0003] The light emitted by LED light sources is scattered and needs to be focused by a light-distributing lens. Therefore, the lens is an important part of motorcycle headlights. It is usually distributed through modules during the manufacturing process. Currently, a common feature of light-distributing lenses is that the light spot presented by the lens is a circular spot.

[0004] Current lens light distribution suffers from poor uniformity, low brightness, and outdated light distribution levels. To address this, we have designed a Class D light distribution LED lens module for motorcycle headlights. Summary of the Invention

[0005] The purpose of this invention is to provide a Class D LED lens module for motorcycle headlights to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solution: A Class D LED lens module for motorcycle headlights, comprising a fixed base plate with four mounting holes and a U-shaped light distribution frame. Two integrally formed mounting plates extend downwards from both sides of the light distribution frame. Both mounting plates are fixed to the top of the fixed base plate by screws. A closed light distribution channel is provided at the bottom of the light distribution frame, connecting to both sides of the frame. An integrally formed small-end connector is provided at the bottom of the closed light distribution channel. Four light-incident small ends are provided at the bottom of the small-end connector. A light source incident channel is opened at the bottom of the four light-incident small ends. A large-end exiting end, connecting to the closed light distribution channel, is installed in the middle of the top of the light distribution frame. Four integrally formed light distribution curved surfaces are provided at the top of the large-end exiting end, each corresponding to one of the four light-incident small ends.

[0007] The aforementioned Class D LED lens module for motorcycle headlights also includes a light source emission mask. Both ends of the light source emission mask are equipped with plate-type mounting bases. The light source emission mask is connected to the top of the light distribution frame via the plate-type mounting bases and screws, covering the large-head emission end. This design facilitates the installation and removal of the light source emission mask, and also allows for better inspection of the light distribution effect.

[0008] In the aforementioned Class D LED lens module for motorcycle headlights, a positioning support is also installed at the top of the light distribution frame. The positioning support positions the plate mounting base. The purpose of this arrangement is to use the positioning support to position the plate mounting base, ensuring the positional accuracy of the plate mounting base within the light distribution frame. This ensures that the light source emission mask accurately covers the large-head emission end.

[0009] In the aforementioned Class D LED lens module for motorcycle headlights, both sides of the bottom end of the small-head connector are equipped with connector limiting posts, which are inserted into the mounting holes at the top of the fixed base plate. This design aims to further improve the positional accuracy and stability of the connection between the entire light distribution frame and the fixed base plate.

[0010] In the aforementioned Class D LED lens module for motorcycle headlights, each light source incident channel is equipped with an LED light source, and each LED light source has a different luminous flux. The purpose of this arrangement is to emit light with different luminous fluxes, allowing the light to enter the light source incident channel and be refracted.

[0011] In the aforementioned Class D light distribution motorcycle headlight LED lens module, the four light-incident tips are flared. This design facilitates better guidance of the light source to emit diverging light.

[0012] In the aforementioned Class D light distribution motorcycle headlight LED lens module, each of the four light source incident channels has a cylindrical light source channel installed inside. This design facilitates further guidance of the light source to emit parallel light, enabling better light distribution operations.

[0013] Compared with the prior art, the advantages of this utility model D-grade light distribution motorcycle headlight LED lens module are as follows: By setting a closed light distribution channel at the bottom of the light distribution frame and connecting it to both sides of the light distribution frame, and setting an integrally formed small end connector and four light-incident small ends at the bottom of the closed light distribution channel, a large end emission end connected to the closed light distribution channel is installed in the middle of the top of the light distribution frame, and four integrally formed light distribution curved surfaces are set on the top of the large end emission end. The four light distribution curved surfaces correspond one-to-one with the four light-incident small ends. D-grade light distribution is adopted to avoid light shining outside the narrow space, thus avoiding waste and light pollution, improving the lighting intensity in different occasions, achieving high uniformity and high brightness light distribution testing, and performing four different levels of light distribution operations.
