Description

Technical Field

[0001] This utility model relates to the field of turn signal technology, specifically a high-performance LED turn signal based on an optimized reflective structure. Background Technology

[0002] In modern transportation, vehicle safety is paramount, and turn signals, as crucial safety warning components, directly impact driving safety and traffic order. With the booming development of the motorcycle industry and consumers' ever-increasing demands for vehicle safety, traditional turn signals can no longer meet the growing needs. Traditional turn signals mostly use incandescent bulbs as their light source, which have low luminous efficiency, converting a large amount of electrical energy into heat. This not only results in high energy consumption but also a short bulb lifespan, leading to frequent replacements and increased operating costs. From an optical perspective, incandescent light diffuses, causing uneven light intensity distribution when transmitting warning signals, especially at long distances or in complex environments, resulting in poor visibility and making it difficult for other road users to accurately judge the vehicle's turning intentions, thus potentially causing traffic accidents.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model discloses a high-performance LED turn signal based on an optimized reflective structure, comprising a lamp housing 1, a top cover 3 on the top of the lamp housing 1, a placement groove 2 inside the lamp housing 1, an LED light panel fixedly installed inside the placement groove 2, a viewing lens 5 on the outer wall of the lamp housing 1, multiple reflectors 14 located behind the LED light panel inside the placement groove 2, multiple micro reflectors arranged on the reflectors 14, a bottom shell 9 at the lower end of the lamp housing 1, multiple micro motors 11 fixedly installed inside the bottom shell 9, multiple bases 12 rotatably installed at the bottom of the placement groove 2, the output end of each micro motor 11 having a rotating shaft that penetrates the lamp housing 1 and connects to the base 12, a groove 13 on the base 12, the bottom of each reflector 14 being inserted into the groove 13 and fixed inside the groove 13 by bolts.

[0023] LED lights demonstrate significant advantages over incandescent lamps in many aspects, including luminous efficiency, energy consumption, lifespan, response speed, environmental performance, size, and design flexibility, meeting the modern society's demand for high efficiency, energy saving, and environmental protection.

[0024] The LED light panel is fixed in the placement slot 2 of the lamp housing 1, serving as the light source for the turn signal. The light emitted by the LED light radiates in all directions, with the rearward-propagating light illuminating the reflector 14 located behind the LED light panel. The micro-reflectors arranged on the reflector 14 operate based on the principle of light reflection. Their surfaces are typically made of highly reflective materials. When light strikes the micro-reflectors, it is reflected according to the law of reflection. These micro-reflectors are arranged in an array, reflecting light in different directions, achieving multi-angle reflection and refraction of light, expanding the light scattering range, and improving the visibility of the turn signal from different viewing angles.

[0025] Reflection Angle Adjustment Mechanism: When the motorcycle needs to turn or adjust the warning range according to different driving scenarios, the control system on the motorcycle will activate the designated micro motor 11. The output end of the micro motor 11 is connected to the base 12 through the lamp housing 1 via a rotating shaft. When the motor rotates, it drives the rotating shaft to rotate, which in turn causes the base 12 to rotate at the bottom of the placement slot 2. Since the bottom of the reflector 14 is inserted into the groove 13 of the base 12 and fixed by bolts, the rotation of the base 12 will drive the reflector 14 to rotate at a specified angle within the placement slot 2, realizing flexible adjustment of the angle of the reflector 14. For example, when driving on urban roads, the angle of the reflector 14 can be adjusted so that the micro reflector reflects more light to the nearby side areas, enhancing the warning effect on pedestrians and non-motorized vehicles; when driving on highways, the light can be concentrated and reflected to a farther and wider area to warn vehicles behind and to the sides.

[0026] In this embodiment, the top cover 3 is fixed to the upper end of the lamp housing 1 by screws 16, and the top of the bottom housing 9 is provided with a positioning plate 10, which is fixed to the lower end of the lamp housing 1 by screws 16.

[0027] The top cover 3 is fixed to the upper end of the lamp housing 1 by screws 16, and the positioning plate 10 at the top of the bottom housing 9 is also fixed to the lower end of the lamp housing 1 by screws 16. This screw 16 fixing method facilitates the installation and disassembly of the top cover 3 and the bottom housing 9, and makes it convenient to repair and replace the internal components of the turn signal.

[0028] In this embodiment, a cavity 17 is provided inside the groove 13, a spring is provided inside the cavity 17, a slot 15 is provided at the bottom of the reflector 14, and a block that cooperates with the slot 15 is provided at one end of the spring. The block is an isosceles trapezoidal structure.

[0029] The reflector 14 is installed using a spring and a locking block inside the cavity 17 of the groove 13. During installation, the bottom of the reflector 14 is aligned with the groove 13 and inserted. The locking block is compressed and retracts into the cavity 17. When the slot 15 corresponds to the locking block, the spring pushes the locking block to pop out and lock into the slot 15, completing the initial fixation of the reflector 14. Then, the bolts are used to further tighten the reflector 14 to ensure that the reflector 14 is installed securely.

[0030] In this embodiment, the outer wall of the lamp housing 1 is provided with an L-shaped groove located above the transparent lens 5. The interior of the L-shaped groove is provided with a reflective strip 7, and the exterior of the L-shaped groove is provided with a transparent shell 6 fixed to the outer wall of the lamp housing 1. The transparent shell 6 is made of transparent glass.

[0031] A reflective strip 7 is installed in the L-shaped groove above the lens 5 on the outer wall of the lamp housing 1, which can further enhance the reflective effect. The outer shell 6 of the L-shaped groove (the shape of the L-shaped groove should match the shape of the reflective strip 7, so it will not be described in detail here) is made of transparent glass, which can protect the reflective strip 7 from external environmental corrosion without affecting the reflection and transmission of light, so that the reflective strip 7 can function stably in different environments.

[0032] In this embodiment, the top of the lamp housing 1 is provided with an annular groove 4 located around the placement groove 2, and a sealing strip is provided inside the annular groove 4.

[0033] A sealing strip is installed inside the annular groove 4, which improves the sealing performance of the top cover 3, prevents rainwater, dust and other substances from entering the lamp housing 1, protects components such as the LED light panel and reflector 14, and extends the service life of the turn signal. A rubber sealing strip can be used for the sealing strip.

[0034] By incorporating multiple miniature reflectors, the reflective structure is significantly optimized. These miniature reflectors reflect and refract light at multiple angles, expanding the light scattering range and ensuring excellent reflectivity of the turn signal from various viewing angles, thus enhancing its ability to transmit warning signals. Whether at a distance or in complex environments (such as rain or fog), other road users can more clearly see the turn signal, accurately judge the vehicle's turning intention, and effectively reduce the risk of traffic accidents.

[0035] The adjustable reflector 14 design allows the turn signal to flexibly adjust the direction of light reflection and the warning area according to the needs of different driving scenarios such as urban roads and highways. In the city, it can effectively warn pedestrians and non-motorized vehicles at close range, while on highways, it can warn vehicles at a greater distance and over a wider area, improving the practicality and applicability of the turn signal and better ensuring driving safety.
