[0002] With the development of the automobile industry, changes in automobile taillights are mostly reflected in the structure and shape, such as single light, combination light, compound light and through rear combination light. Reversing lights have also experienced a development from bulb type to LED particle type, and then to LED and light guide composite type.

[0003] A Chinese patent (publication number CN 215863201 U) discloses an auxiliary projection automobile reversing light optical system, which adds a focusing lens between the LED light source and the baffle to allow more parallel light to converge through the lens and then pass through the baffle, and then form an image on the road surface through the magnifying lens to increase the illumination distance and brightness. However, it is a simple superposition distribution and does not consider the reasonable distribution of the lens and the LED light source, resulting in poor stability. After long-term use of the car, it is easy to cause focusing deviation due to shaking, affecting the lighting effect. Utility Model Content

[0025] Example 1

[0026] In a typical implementation of the present invention, Figure 1-Figure 4 As shown, a concentrator reversing lamp assembly is proposed.

[0027] See also Figure 1 The condenser reversing lamp assembly applies the condenser 7 to the reversing lamp, and allocates the position and connection between the condenser 7, the LED light source 6 and the shell 3, so that the condenser 7 and the LED light source 6 can be stably placed in the shell 3, thereby ensuring the position during long-term operation and meeting the requirements of lighting effects and appearance optical visual effects.

[0028] Specifically, Figure 2 and Figure 3 As shown, the concentrator reversing lamp assembly includes a mask 1, a shell 3 and an LED module. The shell 3 is provided with a storage chamber with an opening. The mask 1 is connected to the shell 3 and seals the opening to form a closed cavity in the storage chamber. The LED module includes an LED light source 6 and a driving board 4. The driving board 4 and the LED light source 6 are both located in the storage chamber and are respectively connected to the shell 3. The closed cavity formed by the storage chamber can prevent external dust, moisture, etc. from entering the interior of the lamp group, reduce the impact on the operation of electrical components, and ensure the stability and durability of the lamp group.

[0029] The LED light source 6 is connected to the driving board 4 through a wiring harness, and a concentrator 7 is provided between the LED light source 6 and the mask 1. The light emitting reference axis of the LED light source 6 is collinear with the reference axis of the concentrator 7. The concentrator 7 is arranged between the LED light source 6 and the mask 1, and ensures that the light emitting reference axis of the LED light source 6 is collinear with the reference axis of the concentrator 7, so that the light emitted by the LED light source 6 can be effectively focused by the concentrator 7, thereby improving the lighting brightness and illumination range of the reversing light.

[0030] The setting of the concentrator 7 helps to form a more concentrated and uniform light beam, making the field of vision behind the vehicle clearer when reversing, and improving the driver's recognition ability. The concentrator 7 extends to the opening position and is connected to the shell 3 for fixation, which helps to fix the position of the concentrator 7 and increase the structural strength of the entire lamp assembly, making the lamp assembly more stable during vehicle driving and less susceptible to vibration.

[0031] The mask 1 and the housing 3 are sealed by infrared preheating, ultrasonic welding or laser welding. The concentrator 7 is 110 mm long in the front-to-back direction of the vehicle body, symmetrically distributed, and connected to the housing 3 by screws. The LED module is connected to the housing 3 by screws.

[0032] Since the depth of the concentrator 7 is too large and the installation point is difficult to arrange, in order to ensure the reliability of the vehicle during driving, in this embodiment, the concentrator reversing light assembly is fixed to the rear bumper by three external screws. The concentrator reversing light assembly and the rear bumper are matched with each other, and the surface difference is designed to be about 1mm lower than the rear bumper.

[0033] In this embodiment, the concentrator 7 and the LED light source 6 are used together. The main function of the concentrator 7 is to focus and guide the light, so that the light emitted by the LED light source 6 can be more concentrated and purposefully irradiated to a specific area; when the light passes through the concentrator 7, it will form a clearer and more obvious light spot, enhancing the visual effect when reversing.

[0034] It is understandable that the shape and structure of the concentrator 7 can be adjusted to achieve precise control of the light, thereby creating different optical effects. For example, the concentrator 7 can be designed so that the light forms a specific pattern or line when it is irradiated on the ground, which can improve the driver's ability to identify the environment behind the vehicle. Since the LED light source 6 itself has the characteristics of high brightness and bright colors, after being combined with the concentrator 7, its optical characteristics can be further highlighted, so that the reversing light has a better visual effect at night or in low light environments.

[0035] The driving board 4 will generate heat when working. If the heat cannot be dissipated in time, it will affect the luminous efficiency of the LED light source 6 and the stability of the driving board 4, and even cause component damage. In this embodiment, a heat dissipation aluminum plate is provided on the driving board 4 to improve the heat dissipation efficiency of the entire assembly, ensure the stable operation of the LED light source 6 and the driving board 4, extend the service life, do not need to set up a separate heat dissipation structure, and save the manufacturing cost of the entire lamp.

[0036] like Figure 3 and Figure 4As shown, the position of the drive board 4 will affect the stability of its connection with the shell 3 and the heat dissipation effect of the entire component. Placing the drive board 4 between the concentrator 7 and the top surface of the containing chamber can ensure that the connection between the drive board 4 and the shell 3 is stable and reliable, and it is also beneficial to the dissipation of heat and improve the reliability of the component.

[0037] The drive board 4 is connected to the vehicle body wiring harness through the external wiring harness 2 passing through the housing 3 to obtain power supply.

[0038] The concentrator 7 needs to be stably fixed in the storage bin to prevent its position from moving and causing inaccurate focusing of light; decorative parts 8 are arranged on both sides of the concentrator 7 in the horizontal direction, and in addition, decorative parts 8 are arranged above and below the concentrator 7 in the vertical direction. By arranging decorative parts 8 on both sides of the concentrator 7 in the horizontal and vertical directions and connecting the decorative parts 8 to the shell 3, the stable position of the concentrator 7 in the vertical and horizontal directions in the storage bin can be ensured, thereby ensuring accurate focusing and projection of light.

[0039] The layout of the decorative parts 8 at the opening will affect the aesthetic appearance of the component and the stability of the overall structure; at the opening of the storage compartment, the decorative parts 8 are distributed around the concentrator 7, which not only enhances the aesthetics of the component, but also further fixes the position of the concentrator 7 and improves the overall structural stability of the component.

[0040] A single LED lamp may not be able to meet the lighting needs when reversing. In this embodiment, the LED light source 6 is provided with a plurality of LED lamps arranged at intervals. The provision of a plurality of LED lamps arranged at intervals can ensure sufficient lighting brightness when reversing. At the same time, through the transmission of the concentrator 7 and the mask 1, the light can be evenly distributed to the outside of the closed cavity, thereby improving the visual experience when reversing.

[0041] The rated power of the selected LED light source 6 is 0.5 W. In other implementations, LED light sources 6 with other powers may also be selected.

[0042] The direct contact between the LED light source 6 and the housing 3 may cause damage or displacement due to vibration or impact; in this embodiment, a buffer is filled between the LED light source 6 and the housing 3, which can effectively reduce the impact of vibration and impact on the LED light source 6, protect it from damage, and maintain its stable position. The buffer can be a sponge pad 5, a porous material elastic pad, etc.

[0043] The reliability, heat dissipation performance, aesthetics and lighting effect of the condenser reversing lamp assembly are improved to provide a safer and more comfortable lighting environment for vehicle reversing.

[0044] Example 2

[0045] In another embodiment of the present invention, Figure 1-Figure 4As shown, a car is proposed.

[0046] Using the condenser reversing lamp assembly as in Example 1, Figure 1-Figure 4 As shown, in this embodiment, the concentrator reversing lamp assembly is fixed to the rear bumper of the car as a whole by three external screws, the concentrator reversing lamp assembly and the rear bumper are clearance-matched, and the surface difference is designed to be about 1 mm lower than the rear bumper.

[0047] For other components of the automobile, existing technical solutions can be adopted and will not be described in detail here.

[0048] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
