Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a bicycle lamp. Background Technology

[0002] With the rapid development of LED technology, the brightness of bicycle lights has been significantly improved, providing better lighting conditions for nighttime cycling. However, existing high-brightness bicycle lights shine directly forward, easily causing glare to oncoming pedestrians and other cyclists, affecting not only the visual comfort of road users but also potentially creating safety hazards. Furthermore, due to the lack of a reasonable light distribution design, a large amount of light is scattered upwards instead of effectively illuminating the road surface, resulting in energy waste. In addition, existing bicycle lights typically only have a single lighting mode and cannot be adjusted according to different cycling environments, making it difficult to simultaneously meet the dual needs of anti-glare on urban roads and long-distance lighting on suburban roads. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a bicycle light with anti-glare function and the ability to independently control high and low beams.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A bicycle light includes: a housing; a light source disposed on the housing; and a light distribution element disposed in front of the light source. The light distribution element is integrally formed and includes a first optical region for forming low beam light distribution and a second optical region for forming high beam light distribution. The first optical region includes a refractive region and a scattering region. The refractive region is used to refract light downwards to the ground, and the scattering region is used to control the light distribution.

[0005] Furthermore, the scattering region fills the first optical region, and the refractive region is disposed within the scattering region.

[0006] Furthermore, the refractive region includes multiple laterally extending horizontal stripes, the width of which is 0.8-1.2 mm. The horizontal stripes are inclined surfaces that face upward toward the light source, used to refract the incident light downward.

[0007] Furthermore, the upper part of the refractive area is provided with inclined horizontal stripes, and the lower part is provided with arc-shaped horizontal stripes. Both the inclined horizontal stripes and the arc-shaped horizontal stripes extend laterally and are inclined upward toward the light source.

[0008] Furthermore, the scattering region includes several vertical stripes arranged in succession to control the distribution of light in the horizontal direction.

[0009] Furthermore, each of the vertical stripes has a width of 0.8-1.2 mm, and the connection between adjacent vertical stripes has a rounded transition of R1.5-2.5.

[0010] Furthermore, the scattering region is circular, and the refraction region is a laterally extending inverted bowl shape, located in the upper middle part of the circular scattering region.

[0011] Furthermore, the first optical region is located in the middle of the light distribution element, and the second optical region is located on both sides of the first optical region.

[0012] Furthermore, each side of the second optical region includes at least one high-beam unit; when multiple high-beam units are included, adjacent high-beam units are closely connected.

[0013] Furthermore, the light source includes a low-beam light source and a high-beam light source, the low-beam light source being configured corresponding to the first optical region, and the high-beam light source being configured corresponding to the second optical region; the low-beam light source and the high-beam light source can be controlled independently.

[0014] The beneficial effects of this utility model are: This invention provides a bicycle lamp comprising a housing, a light source, and an integrally molded light distribution element. The light distribution element includes a first optical region for generating low beam and a second optical region for generating high beam. The first optical region includes a refraction region and a scattering region, effectively solving the aforementioned technical problems. The refraction region refracts upward-facing light downwards to the ground, preventing glare for oncoming riders; the scattering region controls the horizontal distribution of light, ensuring uniform road illumination. This not only achieves high and low beam functionality similar to automobiles, providing an anti-glare lighting experience, but also improves luminous efficiency through the integrally molded light distribution element, allowing more light to effectively illuminate the road surface and avoiding energy waste. Furthermore, the separate high and low beam design allows riders to flexibly choose the lighting mode according to actual road conditions, greatly improving the safety and comfort of nighttime riding.

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0019] Reference Figure 1 , Figure 2 The bicycle lamp of this invention includes a housing 1, a light source 2 disposed within the housing 1, a light distribution element 3 located outside the light source 2, and a lampshade 4 for fixing. The housing 1 serves as the main supporting structure of the entire lamp, and has an internal mounting cavity for accommodating the light source 2 and the light distribution element 3. The light source 2 uses an LED light panel, which is fixed inside the housing 1 with screws to ensure stability under vibration during riding. The light distribution element 3 adopts an integral molding design, including a first optical region 31 for forming low beam light distribution and a second optical region 32 for forming high beam light distribution. The first optical region 31 includes a refraction region 311 and a scattering region 312. The refraction region 311 is used to refract light downwards to the ground, and the scattering region 312 is used to control the light distribution.

[0020] This invention achieves a lighting mode that can be flexibly switched according to different cycling scenarios through the first optical region 31 and the second optical region 32 of the light distribution element 3 and the independently controlled light source 2.

[0021] The first optical region 31 is mainly responsible for forming the near beam distribution. Through the synergistic effect of its internal refractive region 311 and scattering region 312, it achieves anti-glare near-distance lighting, which is suitable for cycling environments with dense pedestrian traffic such as urban roads and sidewalks. The second optical region 32 is responsible for forming the high beam distribution, providing enhanced lighting for cyclists at long distances, which is suitable for suburban roads, sections of road without streetlights, and other scenarios that require long-distance lighting.

[0022] In urban cycling scenarios, cyclists can turn on only the low beam light source 2, at which point the light is mainly distributed through the first optical area 31. The low beam mode satisfies the cyclist's basic vision needs without causing glare to pedestrians and vehicles in the vicinity.

[0023] When cyclists enter dimly lit suburban roads or sections without streetlights, they can turn on the high beam 2 alone or simultaneously turn on both the low beam 2 and the high beam 2. When both the low beam 2 and the high beam 2 are turned on simultaneously, a combined high and low beam lighting mode is achieved. In this mode, the first optical area 31 continues to provide anti-glare short-range illumination, while the second optical areas 32 located on both sides generate a focused long-range beam through their high beam units 321, extending the illumination range to a greater distance ahead. This combined mode allows cyclists to detect road conditions and potential obstacles in advance, greatly improving the safety of nighttime cycling.

[0024] In actual use, the lighting modes can be switched independently. The low beam light source 2 and the high beam light source 2 use independent control circuits, and the rider can switch modes through the control buttons or switches on the handlebars.

[0025] In some embodiments, refer to Figure 2 The scattering region 312 fills the entire first optical region 31, forming a circular area, while the refraction region 311 is located inside the scattering region 312. This allows light emitted from the light source 2 to be processed by two different optical structures simultaneously: light illuminating the refraction region 311 is refracted downwards to the ground by its horizontal stripe structure, forming an anti-glare main illumination beam; while light illuminating the scattering region 312 outside the refraction region 311 is diffused horizontally through the vertical stripes 3121, supplementing the illumination range on both sides of the main beam. The combined effect of these two light sources achieves a more comprehensive light distribution effect.

[0026] In some embodiments, refer to Figure 2The refractive region 311 is a laterally extending, inverted bowl shape, positioned in the upper middle part of the circular scattering region 312 to meet the actual usage angle and lighting requirements of the bicycle lamp. The refractive region 311 includes multiple laterally extending horizontal stripes 3111, each stripe 3111 having a width controlled between 0.8-1.2 mm, preferably 1 mm. These horizontal stripes 3111 are upwardly inclined surfaces facing the light source 2, with an inclination angle of approximately 30 degrees, effectively refracting the incident light downwards. More specifically, referring to… Figure 3 The upper part of the refractive area 311 has a sloping horizontal stripe 3111a, and the lower part has an arc-shaped horizontal stripe 3111b. Both the sloping horizontal stripe 3111a and the arc-shaped horizontal stripe 3111b extend laterally and tilt upwards toward the light source 2. By combining the sloping and arc surfaces, light incident at different angles can be effectively refracted downwards, achieving a more comprehensive anti-glare effect.

[0027] In some embodiments, the scattering region 312 has a vertical stripe structure, mainly used to control the distribution of light in the horizontal direction. The width of each vertical stripe is also controlled between 0.8-1.2 mm, preferably 1 mm, and the connection between adjacent stripes has a rounded transition of R1.5-2.5, preferably R2. This not only reduces abrupt changes in light and achieves a softer light transition, but also improves the durability of the mold during the manufacturing process.

[0028] In some embodiments, refer to Figure 2 The first optical region 31 is located in the middle of the light distribution element 3 and is mainly responsible for low beam illumination, while the second optical region 32 is located on both sides of the first optical region 31 and is responsible for high beam illumination. The layout of low beam in the middle and high beam on both sides meets the lighting needs of bicycles when riding. The low beam provides basic anti-glare lighting, while the high beam provides illumination over a longer distance when needed.

[0029] Furthermore, refer to Figure 2 Each side of the second optical region 32 includes at least one high-beam unit 321. In practical applications, multiple high-beam units 321 can be set according to lighting requirements, for example, four high-beam units 321 can be set on each of the left and right sides. When multiple high-beam units 321 are included, adjacent high-beam units 321 are closely connected to form a continuous high-beam illumination area, avoiding dark areas between light spots.

[0030] In some embodiments, the bicycle light uses separate low beam light source 2 and high beam light source 2 in terms of light source 2 configuration.

[0031] The low beam source 2 is set in relation to the first optical region 31, and the high beam source 2 is set in relation to the second optical region 32. The low beam source 2 and the high beam source 2 can be controlled independently.

[0032] In practice, the low beam source 2 can use a high-power LED, which works in conjunction with the central first optical area 31; the high beam source 2 uses multiple low-power LEDs, which correspond to the high beam units 321 on both sides. Independent control allows riders to flexibly switch lighting modes according to actual road conditions. In urban areas, the low beam mode can be used to avoid dazzling others, while in suburban or low-light environments, the high beam mode can be activated for better illumination.

[0033] Furthermore, refer to Figure 4 Both the low beam light source 2 and the high beam light source 2 adopt a TIR (total internal reflection) focusing structure 5, which can efficiently converge and project the light emitted by the corresponding LEDs forward to form a long-distance illumination spot. Since the high beam light source 2 and the low beam light source 2 are physically separated on the LED light panel and have independent circuits, the high beam will not interfere with the anti-glare effect of the low beam when it is turned on.

[0034] In some embodiments, the LED light panel is fixed to the lamp head body with screws, and the light distribution element 3 is installed in front of the LED light panel. Finally, the lamp cover 4 and the lamp head body are locked and fixed with screws to form a complete bicycle lamp structure. The entire light distribution element 3 is manufactured using a one-piece molding process, which, compared with the traditional multi-lens combination scheme, not only reduces manufacturing costs but also improves luminous efficiency and reduces light loss when propagating between multiple interfaces.

[0035] This invention achieves both high and low beam distribution effects with a single, integrally molded light distribution element 3, eliminating the need for multiple lens combinations, thus reducing costs while improving luminous efficiency. The fusion of the refractive region 311 and the scattering region 312 in the first optical region 31 effectively solves the glare problem of high-brightness bicycle lights, providing a safer and more comfortable lighting environment for all road users.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
