Description

Technical Field

[0001] This utility model relates to the technical field of vehicle light and signal light functions, and in particular to a projection turn signal. Background Technology

[0002] Under certain road conditions and driving circumstances, turn signal signals may not be easily seen by other vehicles and pedestrians in blind spots when a vehicle is turning. This can lead to traffic accidents.

[0003] Our solution is to add a turn signal light, namely a projection turn signal light. Utility Model Content

[0004] The purpose of this invention is to address the drawback of existing technologies where, under certain road conditions and driving circumstances, turn signal signals are not easily visible to other vehicles and pedestrians in blind spots when a vehicle is turning. This poses a risk of traffic accidents. The proposed invention is a projection turn signal, which, when added to a car or motorcycle, projects a light pattern onto the road surface within a 5-meter radius of the vehicle. The pattern's color (yellow or red) and flashing frequency are synchronized with the turn signal. This provides a wider and more intuitive warning to other vehicles and pedestrians, thereby improving driving safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A projection turn signal, comprising:

[0007] Lamp housing; heat dissipation ribs are provided on the outer side of the lamp housing;

[0008] The light source is installed inside the lamp housing;

[0009] The film module is fixed inside the lamp housing;

[0010] The lens module is fixed inside the lamp housing;

[0011] The headlight lens or front cover is mounted on the headlight housing;

[0012] The driver PCB is located inside the lamp housing and is connected to the light source;

[0013] The wiring harness connects to the driver PCB.

[0014] Preferably, the film module includes a glass film, a light-collecting lens, and a lens housing, with the glass film and the light-collecting lens located inside the lens housing, and the glass film located in front of the light-collecting lens.

[0015] Preferably, the lens group module includes a lens group and a lens group housing, with the lens group housing located inside the lamp housing and in front of the lens housing, and the lens group located inside the lens group housing.

[0016] Preferably, the headlight lens or front cover and the headlight housing are sealed with a sealing ring or adhesive.

[0017] Preferably, a fan and a fan cover are installed on the rear side of the lamp housing, and a universal mounting bracket is provided on the lamp housing.

[0018] Preferably, the light source is a common LED or laser, and the projected light pattern color is yellow or red, which meets the color requirements of turn signal regulations.

[0019] Preferably, the heat dissipation fins are in a horizontal spiral shape, and the glass film is made of glass or plastic.

[0020] The beneficial effects of the projection turn signal described in this utility model are as follows:

[0021] Projection turn signals are installed on the vehicle and connected to the vehicle's control system via wiring harness. When the turn signal is activated, the projection light module simultaneously projects a light pattern onto the road surface and flashes in sync with the turn signal; when the turn signal is deactivated, the projection light turns off simultaneously.

[0022] Compared to the existing turn signal function, the addition of road surface light projection greatly reduces blind spots and improves driving safety.

[0023] Installing projection turn signals on vehicles can compensate for blind spots in existing turn signal signals, enhance visibility, and improve driving safety.

[0024] This invention addresses the needs of the prior art by expanding the angle and recognition of vehicle turn signals, thereby increasing driving safety. Attached Figure Description

[0037] The driver PCB10 is located inside the lamp housing 4 and is connected to the light source 9;

[0038] Wiring harness 11 is connected to drive PCB 10.

[0039] In this embodiment, the film module includes a glass film 6, a light-collecting lens 7, and a lens housing 8, with the glass film 6 and the light-collecting lens 7 located inside the lens housing 8, and the glass film 6 located in front of the light-collecting lens 7.

[0040] In this embodiment, the lens group module includes a lens group 3 and a lens group housing 5, and the lens group housing 5 is located inside the lamp housing 4 and in front of the lens housing 8, while the lens group 3 is located inside the lens group housing 5.

[0041] In this embodiment, the headlight lens or front cover 1 and the lamp housing 4 are sealed by a sealing ring or glue 4.

[0042] In this embodiment, a fan 12 and a fan cover 13 are installed on the rear side of the lamp housing 4, and a universal mounting bracket 14 is provided on the lamp housing 4.

[0043] In this embodiment, the light source 9 is a common LED or laser, and the color of the projected light pattern is yellow or red, which meets the color requirements of the turn signal regulations.

[0044] In this embodiment, the heat dissipation fins are arranged in a horizontal spiral, and the glass film 6 is made of glass or plastic.

[0045] In this embodiment, the light source 9 (ordinary LED or laser) is installed at the bottom of the lamp housing 4. Then, the patterned glass film 6, the light-collecting lens 7, and the housing 8 are assembled into a film module, which is then fixed to the lamp housing 4. Next, the lens group 3 (with 3 to 8 lenses) and the lens group housing 5 are assembled into a lens group module, which is then fixed to the lamp housing 4. Finally, the headlight lens or front cover 1 is installed onto the lamp housing 4 and sealed with a sealing ring or adhesive 2. The fan 12 and fan cover 13 are installed at the rear of the lamp housing 4, and finally, the universal mounting bracket 14 is installed onto the lamp housing 4.

[0046] In this embodiment: 1. The lens group 3 consists of multiple lenses, ranging from 3 to 8 lenses, and the lens material can be glass or transparent plastic. 2. The universal mounting bracket 14 can freely adjust the angle and direction of the lamp. 3. The headlight lens can be hollow in the middle or a single piece. When used as an opaque front cover, it is hollow in the middle to allow light to pass through. 4. The lens group 3, the glass film 6, and the light-collecting lens 7 can also be assembled together in the same lens group housing 5.

The appropriate angle of the light is adjusted using the universal mounting bracket 14, and the wiring harness 11 of the light is connected to the vehicle's control system. When the vehicle turns, the turn signal is transmitted to the light's driver circuit board (driver PCB 10) through the wiring harness 11. Upon receiving the signal, the light source 9 illuminates, and the fan 12 also starts to aid in heat dissipation. The light passes through the front light-receiving lens 7 and is then projected onto the patterned and colored glass film 6. The patterned and colored light is then processed by the lens group 3 to form a light pattern of ideal size, clarity, and brightness, which is finally projected onto the road surface near the vehicle and flashes synchronously with the vehicle's existing turn signals. When the turn signal is turned off, the projected turn signal also turns off synchronously.

[0051] According to turn signal regulations, the projected pattern is yellow or red. When other vehicles and pedestrians see the projected light and shadow pattern on the ground, they can easily recognize it as a turn signal reminder, thus improving driving safety.
