Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted auxiliary driving lights, in particular to a novel structure of a vehicle-mounted auxiliary driving light with adjustable color temperature. Background Art

[0002] In rainy and foggy weather, turning on yellow driving lights will have a better effect because yellow light has strong penetration. Vehicle-mounted auxiliary driving lights usually install both white and yellow lights, and the two vehicle-mounted auxiliary driving lights are switched through a switch to meet the driving lighting requirements at that time. The utility model provides a novel structure in which white and yellow LEDs are arranged under the same lens, and an external dimming controller is used to control the brightness of the white and yellow LEDs, so as to achieve a stepless color temperature adjustment lighting effect.

[0003] Regarding the above related technologies, the inventor believes that the following defects exist:

[0004] Currently, vehicle-mounted auxiliary driving lights usually only have one color of light, such as single white light or single yellow light. The white light has a higher brightness and better lighting effect. However, when driving in rainy and foggy weather, the reflection of white light is very strong, which is likely to cause visual fatigue to the driver. Content of the Utility Model

[0005] In order to improve the problem of needing to install both white and yellow auxiliary driving lights at the same time, this application provides a novel structure of a vehicle-mounted auxiliary driving light with adjustable color temperature. White and yellow LEDs are arranged under the same lens, and an external dimming controller is used to control the brightness of the white and yellow LEDs, so as to achieve a vehicle-mounted auxiliary driving light with stepless color temperature adjustment, simplify the actual installation difficulty of modifying the vehicle lights and save installation space.

[0006] This application provides a novel structure of a vehicle-mounted auxiliary driving light with adjustable color temperature, adopting the following technical scheme: A novel structure of a vehicle-mounted auxiliary driving light with adjustable color temperature includes a lamp body housing, a light source driving board, driving board fixing screws, an optical lens, and optical lens fixing screws. The light source driving board further includes: a driving board, a white LED, and a yellow LED. The light source driving board is fixed inside the lamp body housing through the driving board fixing screws. The white LED is surface-mounted and soldered on the driving board. The yellow LED is electrically connected below the white LED. The white LED and the yellow LED are electrically connected to an external stepless dimming controller.

[0007] Further setting: The yellow LED is fixed to the driving board by soldering, and an optical lens is installed on the light source driving board.

[0008] Further setting: There are positioning holes and positioning posts between the optical lens and the light source driving board.

[0009] Further, the optical lens fixing screw passes through the hole of the optical lens and is threadedly connected to the lamp body housing.

[0010] Compared with the related art, a novel structure of an in-vehicle auxiliary driving lamp with adjustable color temperature provided by the present utility model has the following beneficial effects:

[0011] The present utility model provides a novel structure of an in-vehicle auxiliary driving lamp with adjustable color temperature, which solves the problem that the current in-vehicle auxiliary driving lamp has only a single color of light. If multiple colors are required, different colored lamps need to be installed and switched through a switch. This makes the installation of modified vehicle lamps difficult and wastes installation space. The present utility model arranges white light LEDs and yellow light LEDs under the same lens. Not only can the white and yellow dual-color function be realized, but also the brightness of the white and yellow two-way lamp beads can be separately controlled through an external controller, achieving the effect of stepless color temperature adjustment, increasing the applicable environment of the lamp and saving installation space.

[0016] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The typical embodiments of the present utility model are shown in the drawings.

[0017] Embodiment 1:

[0018] As Figure 1-2 shown, a novel structure of an in-vehicle auxiliary driving lamp with adjustable color temperature of the present utility model includes a lamp body housing 1, a light source driving board 2, a driving board fixing screw 3, an optical lens 4, and an optical lens fixing screw 5. The light source driving board 2 further includes: a driving board 21, a white light LED 22, and a yellow light LED 23. The white light LED 22 and the yellow light LED 23 are electrically connected to an external stepless dimming controller.

[0019] As Figure 2-3As shown in the figure, the light source driving board 2 is fixed inside the lamp body housing 1 by driving board fixing screws 3. The white light LED 22 is fixed on the surface of the driving board 21 by soldering. A yellow light LED 23 is electrically connected below the white light LED 22. The yellow light LED 23 and the driving board 21 are fixed together by soldering. An optical lens 4 is installed on the light source driving board 2. There are positioning holes and positioning posts between the optical lens 4 and the light source driving board 2, so that they cannot move horizontally. The optical lens fixing screw 5 passes through the hole of the optical lens 4 and is threadedly connected to the lamp body housing 1.

[0020] In implementation, the white light LED 22 and the yellow light LED 23 are respectively controlled by two circuits and are used by connecting an external stepless dimming controller. In this way, the brightness adjustment of these two colors of lights from 0% to 100% can be controlled. When the two lamp beads light up together, a mixed-color light spot is obtained, thus realizing the function of a driving lamp with stepless color temperature adjustment.

[0021] The advantages of this technical solution in practical applications include but are not limited to the following points:

[0022] 1. It is emphasized that the optical lens 4 is installed on the light source driving board 2, making the color of the light spot more uniform;

[0023] 2. The setting of the stepless dimming controller controls the brightness adjustment of the two colors of lights from 0% to 100%. When the two lamp beads light up together, a mixed-color light spot is obtained, thus realizing the function of a driving lamp with stepless color temperature adjustment.

[0024] This technical solution arranges two-color LED lamp beads, namely the white light LED 22 and the yellow light LED 23, under the same lens. In this way, when the white and yellow LEDs light up at the same time, the color mixing degree of the light will be better. The brightness of these two LEDs is controlled by an external dimming controller to obtain the effect of stepless color adjustment, and the color of the light spot projected is also more uniform.

[0025] The above are only exemplary embodiments of the present disclosure, and the scope of the present disclosure cannot be limited thereby. That is, all equivalent changes and modifications made in accordance with the teachings of the present disclosure still fall within the scope covered by the present disclosure. Those skilled in the art will easily think of other implementation schemes of the present disclosure after considering the specification and the disclosure of the practical truth. This application aims to cover any variations, uses, or adaptive changes of the present disclosure, and these variations, uses, or adaptive changes follow the general principles of the present disclosure and include common general knowledge or conventional technical means in the technical field not recorded in the present disclosure.
