Description

Technical Field

[0001] This utility model relates to the field of lighting technology for bicycle lights, and in particular to a multifunctional bicycle light. Background Technology

[0002] Existing bicycle speedometers are typically mounted upwards at the center of the handlebars using a bracket for riders to view data. However, when a lighting device is also needed, the common practice is to fix the headlight directly above the speedometer or in the same mounting position on the speedometer bracket. This causes the headlight beam to rise in sync with the speedometer's tilt, failing to effectively illuminate the road ahead. While this mounting method facilitates integration, it severely limits the lighting function, potentially posing a safety hazard, especially at night or in dimly lit environments. Currently, there is a lack of integrated mounting structures on the market that simultaneously accommodates the speedometer's viewing angle requirements and the headlight's adjustable angle. Most riders are forced to choose separate installations or sacrifice lighting performance, impacting both convenience and safety.

[0003] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described below.

[0020] 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. The various technical features in this utility model can be combined interactively without contradicting each other.

[0021] Reference Figures 1 to 3 This utility model provides a multifunctional bicycle light, comprising a housing 1 and a light-emitting component 2. The housing 1 is used to mount various components, specifically, the housing 1 has mounting cavities for mounting the various components; the front end of the housing 1 also has an opening 11 communicating with the mounting cavity. The light-emitting component 2 includes a light source 21 and a lens 22. The light source 21 is used to emit light into the opening 11, and the lens 22 is used to change the propagation path of the light. Specifically, the optical axis of the lens 22 is inclined downward relative to the mounting reference surface of the housing 1, and the light emitted from the light source 21 is inclined downward after being acted upon by the lens 22. By adjusting the light path of the light emitted from the light source 21 through the lens 22, the light can be accurately projected onto the ground, effectively avoiding upward illumination that would affect the road lighting effect.

[0022] In this embodiment, the light source 21 is set as an LED light board, and LED beads are provided on the LED light board. The LED beads are highly efficient and have a long service life, which helps to reduce production costs.

[0023] Reference Figure 2 and Figure 3Furthermore, the lens element 22 includes a first lens portion 221 and second lens portions 222 disposed on opposite sides of the second lens portions 222. The first lens portion 221 has a concave structure, and its inner surface is configured as a total internal reflection surface. An emission groove is formed on the surface of the first lens portion 221 facing the mounting cavity, and the emission groove is used to place LED beads. The light emitted from the light source element 21 first enters the first lens portion 221 through its incident surface; some light reaches the light-emitting surface directly, and some light reaches the light-emitting surface after being reflected by the total internal reflection surface; the light reaching the light-emitting surface is diverged by the concave structure.

[0024] Furthermore, the light-emitting surface of the first lens section 221 is provided with a plurality of prismatic vertical stripe structures for diffusing light in the horizontal direction. Some light is reflected by the inner surface, and when it reaches the concave light-emitting surface, the concave surface itself has a diverging effect, while the raised vertical stripe is equivalent to a tiny cylindrical lens, which performs secondary diffusion and control of the light in the direction perpendicular to the vertical stripe (i.e., the horizontal direction).

[0025] This technical solution uses a tilted lens element 22 to form a basic downward-deflecting light path. The concave surface diffuses the light, while the raised vertical ridges act as a cylindrical lens array, primarily strongly diffusing the light horizontally, significantly increasing the illumination width. The combined effect of the concave surface and the vertical ridges in the vertical direction, along with the tilt angle, effectively focuses or precisely controls the upward-scattered light, forming a cutoff line between light and shadow to avoid glare. This arrangement projects a wide and uniform illumination area onto the road surface in front of the bicycle, covering the bicycle lane and part of the side areas (such as the edge of the sidewalk), increasing the cyclist's visibility and sense of safety. Simultaneously, it significantly reduces or even eliminates glare directly hitting the eyes of oncoming pedestrians, cyclists, or drivers, improving public safety.

[0026] In this embodiment, the LED light panel is provided with two LED beads arranged side by side, and the lens element 22 is provided with two first lens portions 221 that correspond one-to-one with the two LED beads.

[0027] Furthermore, the light-emitting surface of the second lens section 222 has a planar structure, and the surface of the second lens section 222 facing the mounting cavity has several raised vertical grooves. The first lens section 221 can only transmit light projected directly from the LED, while the second lens section 222 is used to transmit light emitted from the side and rear of the LED. The several raised vertical grooves on the second lens section 222 act as tiny cylindrical lenses or prisms, diffusing the side spill light from the light source 21 in the horizontal direction and / or deflecting it in the vertical direction. By using the second lens section 222 to homogenize this disordered side light and convert it into near-field floodlight, the light efficiency is effectively improved, and the blind spot of the high beam illumination of traditional bicycle lights at close range can be compensated for. The planar light-emitting surface makes the light pattern transition natural and does not produce glaring bright spots.

[0028] In this embodiment, the lens element 22 is detachably connected to the housing 1. Specifically, the edge of the second lens part 222 is provided with a connecting part 223, and a limiting protrusion 224 is provided on the connecting part 223. A limiting groove 14 is provided on the inner wall of the housing 1. The limiting protrusion 224 and the limiting groove 14 are engaged to realize the connection and fixation between the lens element 22 and the housing 1.

[0029] Reference Figure 2 Furthermore, the lens element 22 is integrally molded. By integrating all optical surfaces into a single component through a one-time injection molding process, production efficiency and the consistency of the lens element 22 are effectively improved.

[0030] Reference Figure 2 and Figure 3 Furthermore, a heat sink 3 is provided on the lower surface of the housing 1. A mounting boss 31 is provided on the side of the heat sink 3 near the opening 11. A clearance hole is provided on the housing 1, and the mounting boss 31 extends into the housing 1 through the clearance hole. The LED light board is fixedly mounted on the mounting boss 31, which is inclined towards the opening 11. The inclined mounting boss 31, with the LED light board mounted on it, further alters the direction of light, ensuring that the light emitted from the lighting fixture can be projected onto the ground. The LED light board can be connected and fixed to the heat sink 3 using common fasteners such as screws.

[0031] By setting the heat sink 3, the heat dissipation of the light source component 21 can be accelerated, effectively improving the service life of the light source component 21. Preferably, the heat sink 3 is a heat-dissipating aluminum plate. The heat sink 3 is injection molded to the housing 1 and is set on the lower surface of the housing 1, so that the heat sink 3 is in full contact with the air, which is conducive to further accelerating heat dissipation.

[0032] In this embodiment, the mounting boss 31 forms an angle of 10° with the vertical direction.

[0033] Reference Figure 1 and Figure 2Furthermore, a odometer rotating base 12 is provided on the upper surface of the housing 1, and a odometer bracket fixing base 13 is provided on the lower surface of the housing 1. The odometer bracket fixing base 13 is used to connect to the odometer bracket, allowing the entire lighting fixture to be mounted on the odometer bracket. The odometer rotating base 12 is used to install the odometer, which is connected to the odometer rotating base 12 by a rotating snap-fit ​​mechanism, placing the odometer on the top surface of the lighting fixture for easy reading of odometer data while also maintaining the lighting function of the lighting fixture. Both the odometer rotating base 12 and the odometer bracket fixing base 13 can be connected and fixed to the housing 1 using common fasteners such as screws.

[0034] Furthermore, the light-emitting component 2 also includes a PCB board 23 and a battery (not shown in the figure). The battery is electrically connected to the PCB board 23 to power the entire device. The light source component 21 is electrically connected to the PCB board 23, and the PCB board 23 can control the light source component 21 to switch between different operating states. The PCB board 23 is connected to a USB / Type-C charging port 24 for battery charging and a push-button switch 25 for changing the operating mode of the light source component 21. A through hole is provided on one side of the housing 1 for the charging port 24 and the push-button switch 25 to extend out of the housing 1. A removable silicone plug 26 is provided on the side wall of the housing 1 for waterproofing and dustproofing the USB / Type-C charging port 24 and the push-button switch 25.
