Car door handle lights, as a user-friendly design, aim to enhance driving and passenger convenience. With the continuous advancement of automotive technology and consumers' increasing demands for vehicle comfort and safety, door handle lights have gradually become standard equipment or optional accessories on many models. From their initial simple lighting function to today's welcome lights with various lighting effects and intelligent control functions, the technology has undergone continuous development and improvement. The main function of door handle lights is to provide illumination; when the door is opened, the welcome light illuminates the ground below the door, facilitating passenger entry and exit. This design is particularly practical at night or in low-light environments.

[0003] The technical solution of patent CN 20524532 U provides a structure for a car door handle light with a laser pattern. This utility model includes a light housing and a door handle cover, in which a light source, a circuit board, and a light guide are disposed. Light is emitted by the light source, passing through the cover to illuminate the surrounding environment. The structure is simple, has a strong aesthetic effect, and is conducive to promotion and application.

[0004] However, this solution's light-emitting module occupies space inside the handle, and the lighting device only illuminates the door recess or emits light directly from inside the handle outwards, resulting in limited lighting area and brightness. Furthermore, this solution has poor sealing, making it susceptible to water ingress and unsuitable for long-term use. Utility Model Content

[0005] The present invention aims to overcome the problems of uneven lighting and encroachment on the internal space of the handle in the prior art, and provides a door handle light to overcome the above defects.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0008] The light guide includes a light-emitting device connected to a door handle, a ring-shaped protective device located on the outside of the light-emitting device for protection and waterproofing, and a light guide device for transmission. The light guide device includes a light guide. One end of the light guide is provided with stepped optical teeth for eliminating bright spots at the end of the light guide. The other end is a connector that rests on the optical teeth for connecting the light-emitting device.

[0009] This utility model includes an illumination device, a light guide device, and a protective device. The light guide device includes a light guide for receiving light emitted from the illumination device and guiding it to other components. The optical teeth are used to control or optimize the propagation and distribution of light, employing a sawtooth structure or other shaped micro-tooth surface structure. One end of the light guide has a stepped optical tooth structure to prevent excessive brightness at the tail end, which could disrupt the uniformity of the entire light-emitting surface and help ensure overall uniform light emission. Simultaneously, the other end of the light guide has a connector resting on the optical teeth, facilitating connection to subsequent devices and ensuring the integrity of the device. Both the light guide device and the illumination device are housed within the protective device, effectively saving overall space.

Reducing the bright spots allows the light to be better dispersed throughout the entire area, improving the overall light utilization rate and reducing energy consumption. On the other hand, reducing the bright spots effectively reduces glare, minimizes eye strain, and improves visual comfort.

[0016] Preferably, the protective device includes a light guide bracket for assembly and positioning, which seals the light guide, PCB board, and LED inside.

[0017] This invention can seal the light guide bracket by means of potting glue or wire plug sealing, which provides a certain degree of protection and waterproof function for the lighting device and the light guide, and helps to reduce damage to the above-mentioned devices and increase their service life.

[0018] Preferably, the light guide bracket is made of plastic, and a first soft rubber is provided on the outside of the light guide bracket to provide protection and increase the airtightness of the light guide bracket.

[0019] This invention adds a first soft rubber structure to the outside of the optical guide bracket, effectively achieving waterproof, dustproof, and pollution-proof functions. The soft rubber material has excellent elasticity and flexibility, easily adapting to interfaces of different shapes to achieve a tight fit, thus ensuring a good sealing effect. At the same time, the sealing soft rubber material has good aging resistance, chemical corrosion resistance, and weather resistance, extending the service life of equipment or products and reducing maintenance and replacement costs. Furthermore, it helps to reduce manufacturing and assembly difficulties and improve production efficiency.

[0020] Preferably, a light-shielding rib can be provided near the connector of the first light guide to block light leakage from the LED light source and prevent bright spots from appearing.

[0021] This invention provides light-shielding ribs on specific areas or components, which can effectively block or disperse light, prevent bright spots, reduce light intensity, and avoid excessive light causing discomfort or damage to the eyes or other objects.

[0022] Preferably, the connection device further includes a wiring harness for connecting an external power source to power the lighting device.

[0023] This utility model provides a connecting wire harness to connect the lighting device and an external power supply, thereby providing power to the lighting device.

[0024] Preferably, the connection device includes an outer lampshade that encloses the light guide bracket and the connecting wire harness to protect the internal components.

[0025] This invention features an outer lampshade to protect the entire device, preventing the lamp body from external impacts and damage, reducing damage caused by accidental collisions, and thus extending the lamp's lifespan. The lampshade also prevents dust and oil from entering the lamp body, keeping the lamp clean and intact, and reducing light weakening and lamp damage caused by dust accumulation.

[0026] Preferably, the outer lamp cover is a transparent or diffused plastic part, and a second soft rubber is provided on the outside of the plastic part to provide protection and increase the overall airtightness and waterproofness.

[0027] This invention also incorporates soft rubber at the connection point of the outer lamp cover, which helps ensure the airtightness of the connection and effectively prevents dust and water damage.

[0028] Therefore, this utility model has the following beneficial effects:

[0029] (1) This utility model can be installed inside the car door handle, without occupying the volume of the car handle, saving space and improving the overall aesthetics.

[0030] (2) This utility model achieves a large-area ring-shaped high-brightness uniform lighting effect for the entire handle through optical teeth, light-shielding ribs and other structures, weakens the bright spots generated when light is coupled into the light guide, and prevents the tail from being too bright.

[0031] (3) By setting the first soft rubber and the second soft rubber, this utility model ensures high sealing performance of the overall structure, avoids damage to the device due to water ingress, and increases the service life of the device.

[0032] (4) This utility model is simple to operate, has a clear structure, and is highly safe, which is conducive to its application and promotion in actual production. Attached Figure Description

The addition of the first and second soft adhesives 311 effectively achieves waterproofing, dustproofing, and pollution prevention. The soft adhesive material has excellent elasticity and flexibility, easily adapting to interfaces of different shapes to achieve a tight fit, thus ensuring a good sealing effect. Simultaneously, the sealing soft adhesive material has good aging resistance, chemical corrosion resistance, and weather resistance, extending the service life of equipment or products and reducing maintenance and replacement costs. Furthermore, it helps to reduce manufacturing and assembly difficulties and improve production efficiency.

[0053] The specific usage process of the example is as follows:

[0054] First, the LED 11 of the lighting device 10 is installed on the PCB board 12. The edge of the PCB board 12 is connected to the connector 23 of the light guide 21 of the light guide device 20.
