Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically to an ultra-thin modular integrated LED signal light. Background Technology

[0002] Automotive signal lights are various traffic lights installed on automobiles to ensure safe driving. They are divided into two categories: lighting lights and signal lights. Signal lights include position lights, brake lights, and turn signals. Position lights are installed at the front and rear of the vehicle to indicate the presence and width of the vehicle; brake lights are installed at the rear to indicate that the vehicle is slowing down or stopping; turn signals are installed at the front, rear, and sides to indicate that the vehicle is turning.

[0003] Existing automotive signal lights consist of LED lights and circuit boards. Multiple LED lights are mounted on the same circuit board. Since the circuit board itself is flat, this limits the installation methods of different signal lights, resulting in a monotonous design. The circuit board is generally installed behind a thick-walled component with a light distribution pattern, which also makes the integrated LED signal light relatively thick, affecting the installation of the signal light. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an ultra-thin modular integrated LED signal light.

[0005] Technical solution

[0006] The ultra-thin modular integrated LED signal light includes a lamp housing with multiple light zones. Each light zone has a light guide plate and an LED light source arranged opposite each other. One light zone is semi-enclosed or fully enclosed on the outside of the lamp housing. Several other light zones are arranged side by side on the outside of the central area of ​​the lamp housing, and the remaining light zones are arranged side by side on the inside of the central area of ​​the lamp housing. The LED light sources of the outer light zones are mounted on a first circuit board, which is located behind the light guide plate of the outer light zones. The LED light sources of the outer light zones in the central area are mounted on the same second circuit board, which is located inside or outside the light guide plate of the central area. The LED light sources of the inner light zones in the central area are mounted on the same third circuit board, which is located at the bottom or top of the light guide plate of the inner light zones in the central area.

[0007] Furthermore, the light area includes a daytime running light area, a turn signal area, a brake light area, a reversing light area, a fog light area, and a taillight area. The daytime running light area is arranged in a semi-enclosed or fully enclosed manner on the outside of the lamp housing. The turn signal area, brake light area, and reversing light area are arranged side by side on the outside of the central area of ​​the lamp housing. The fog light area and taillight area are arranged side by side on the inside of the central area of ​​the lamp housing.

[0008] Furthermore, the light guide plates for all light areas include an incident surface and an exit surface. The light emitted by the LED light source in the outer light area of ​​the lamp housing enters the light guide plate through the incident surface and is refracted to the exit surface and emitted in parallel. The light guide plates for the outer and outer light areas of the central area also include a collimating surface. The light emitted by the LED light source in the outer and outer light areas of the central area is refracted by the light guide plate and then undergoes total internal reflection through the collimating surface to form parallel light that is emitted from the exit surface.

[0009] Furthermore, the light guide plate has a light distribution pattern on its emission surface.

[0010] Furthermore, a retroreflector mounting area is provided around the outer lamp area of ​​the lamp housing, and a retroreflector is installed in the retroreflector mounting area.

[0011] Furthermore, the outer light area of ​​the lamp cover housing is a rectangular ring, U-shaped, or L-shaped shape, the outer light area of ​​the central area is a horizontal rectangular strip, and the inner light area of ​​the central area is a vertical rectangular strip.

[0012] Beneficial effects:

[0013] This invention provides an ultra-thin modular integrated LED signal light, which distributes multiple light zones into three different areas: the outer side of the lamp housing, the outer side of the central area, and the inner side of the central area. The outer side has only one light zone, arranged in a semi-enclosed or fully enclosed configuration. Multiple light zones are arranged side-by-side on the outer side of the central area, and multiple light zones are arranged side-by-side on the inner side of the central area. The LED light sources for the same area are mounted on the same circuit board. Different light guide plates with varying structures allow for installation in different orientations, providing diverse installation options. Each area can be optimized. This design offers more light zone layouts and diverse shapes. By selecting light guide plates of appropriate thickness and refractive index, the desired light distribution effect can be achieved while designing an ultra-thin LED signal light.

[0016] The present invention will now be described in detail with reference to the accompanying drawings.

[0017] As attached Figure 1 To be continued Figure 4 . Specific implementation examples:

[0019] The ultra-thin modular integrated LED signal light includes a lamp housing 1, on which multiple light zones are provided. Each light zone has a light guide plate 2 and an LED light source 3 arranged opposite each other. One light zone is arranged in a semi-enclosed or fully enclosed shape on the outside of the lamp housing 1, while multiple other light zones are arranged side by side on the outside of the central area of ​​the lamp housing 1. Figure 1 Taking the right-side taillight as an example, the outer side of the central area refers to the right side of the central area; the remaining light areas are arranged side-by-side on the inner side of the central area of ​​the lamp housing 1, with... Figure 1 Taking the right-side taillight as an example, the inner side of the central area refers to the left side of the central area; the LED light source 3 of the outer light area is set on the first circuit board 4, which is located behind the light guide plate 2 of the outer light area. Since the light guide plate 2 has a certain light guiding length, and the outer light area is longer, the LED beads of the LED light source 3 of the outer light area can be arranged along the outer light area. The light guide is from the thickness direction of the light guide plate 2, which can ensure the uniformity of light in each part; the LED light source 3 of the outer light area of ​​the central area is set on the same second circuit board 5, which is located inside or outside the light guide plate 2 of the central area. Then, multiple LED light sources 3 can be arranged side by side on the second circuit board 5 along the height direction; the LED light source 3 of the inner light area of ​​the central area is set on the same third circuit board 6, which is located at the bottom or top of the light guide plate 2 of the inner light area of ​​the central area. Then, multiple LED light sources 3 can be arranged on the third circuit board 6 along the horizontal direction.

[0020] With the above structure, the ultra-thin modular integrated LED signal light of this invention requires three different circuit boards to integrate the various LED light sources 3 of the signal lights. The three different circuit boards differ in their installation orientation, therefore requiring three different light guide plates 2 to meet the light adjustment needs. Compared to integrating all LED light sources 3 onto a single circuit board, the LED signal light of this invention can be configured in various ways and is not limited to any particular design. Figure 1The diagram shows a combination of three light zones on the outer side of the central area and two light zones on the inner side of the central area. This invention can also be a combination of two light zones on the outer side of the central area and three light zones on the inner side of the central area. This configuration can meet the luminous area requirements of different types of traffic lights and can be combined with semi-enclosed or fully enclosed light zones on the outer side to form various light zone layouts, and is not limited to... Figure 1 The U-shaped structure can be partially enclosed on the right or left. By selecting a light guide plate 2 with appropriate thickness and refractive index, ultra-thin LED signal lights can be designed while achieving the desired light distribution effect.

[0021] In a preferred embodiment of this utility model, the light area includes a daytime running light area 7, a turn signal area 8, a brake light area 9, a reversing light area 10, a fog light area 11, and a taillight area 12. The daytime running light area 7 is arranged in a semi-enclosed or fully enclosed manner on the outside of the lamp housing 1. The turn signal area 8, the brake light area 9, and the reversing light area 10 are arranged side by side on the outside of the central area of ​​the lamp housing 1. The fog light area 11 and the taillight area 12 are arranged side by side on the inside of the central area of ​​the lamp housing 1.

[0022] like Figure 2-4 As shown, the light guide plate 2 of all light areas includes an incident surface 21 and an exit surface 22. The light emitted by the LED light source 3 in the outer light area of ​​the lamp housing 1 enters the light guide plate 2 through the incident surface 21 and is refracted to the exit surface 22 and emitted in parallel. The light guide plate 2 of the outer and inner light areas of the central area also includes a collimating surface 23. The light emitted by the LED light source 3 in the outer and inner light areas of the central area is refracted by the light guide plate 2 and then undergoes total internal reflection through the collimating surface 23 to form parallel light that is emitted from the exit surface 22.

[0023] The light guide plate 2 has a light distribution pattern 24 on its emission surface 22. The light distribution pattern 24 is a fisheye pattern, which can transform parallel light into a light pattern that meets the requirements.

[0024] A retroreflector mounting area 13 is provided on the outer periphery of the lamp area of ​​the lamp housing 1, and a retroreflector is installed in the retroreflector mounting area 13.

[0025] As one design of this utility model, the outer light area of ​​the lampshade housing 1 is a rectangular ring, U-shaped or L-shaped, the outer light area of ​​the central area is a horizontal rectangular strip, and the inner light area of ​​the central area is a vertical rectangular strip.

[0026] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
