Description

Technical Field

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

[0002] Traditional cycling lights, especially headlights, often excessively restrict the beam's focusing ability or beam angle in an attempt to avoid glare for oncoming pedestrians and vehicles. This results in insufficient effective illumination distance and a narrow field of vision, making it difficult to meet the needs of nighttime cycling for predicting road conditions at medium to long distances and for providing adequate floodlight to the surrounding environment, thus posing safety hazards. On the other hand, designs that prioritize high brightness and long range tend to produce intense, glare, affecting the visual comfort and safety of road users and failing to meet the increasingly important requirements for road-friendly lighting.

[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 bicycle lamp, including a lamp body 1, a lamp plate 3, and a lens 2. The lamp body 1 is used to mount the various components. Specifically, the lamp body 1 has a mounting cavity 11 for mounting the components, and an opening 12 at the front end of the lamp body 1 communicating with the mounting cavity 11. The lamp plate 3 is disposed within the mounting cavity 11 and is used to emit light into the opening 12. The lens 2 is disposed at the opening 12, corresponding to the lamp plate 3, and is used to change the propagation path of the light.

[0022] Reference Figure 1 and Figure 2Specifically, one side of the lens element 2 is configured as the light-incident surface, and the other side is configured as the light-exit surface, with the light-incident surface facing the lamp panel 3. The lens element 2 includes a first lens 21 and a second lens 22. The second lens 22 is disposed around the periphery of the first lens 21 and is configured as a concave lens. The first lens 21 includes a convex lens portion 211 and a cylindrical lens 212. The convex lens portion 211 is disposed in the middle of the lens element 2 to converge light, and a plurality of cylindrical lenses 212 are symmetrically arranged on both sides of the convex lens portion 211. The lens element 2 is configured as a composite structure of a first lens 21 and a second lens 22. The convex lens 211 in the center converges a portion of the light, forming a collimated and relatively bright central light spot. An array of cylindrical lenses 212 acts on the light from both sides of the central area, transforming the point light source into a collimated rectangular light spot with uniform width. This creates a uniformly illuminated rectangular light spot outside the central spot, resulting in a central illumination beam with a long range and uniform beam. A concave lens further diverges the light from the periphery, producing a soft, wide-range floodlight around the central rectangular light spot, further increasing the beam width to meet lighting requirements. The lens element 2 of this invention integrates the light emitted from the point light source of the lamp panel 3 through the combination of a concave lens, an array of cylindrical lenses 212, and a central convex lens, forming a soft and uniformly transitioned rectangular light spot, effectively meeting the requirements of anti-glare, non-dazzling, long-range, and wide-range floodlight for cycling lighting.

[0023] Furthermore, an array of cylindrical lenses 212 is disposed on the upper and lower sides of the convex lens portion 211, and a plurality of cylindrical lenses 212 are arranged radially along the lens element 2.

[0024] In this embodiment, the lamp board 3 is an LED lamp board 3 with LED lamp beads. The LED lamp beads are highly efficient and have a long service life, which helps to reduce production costs.

[0025] Reference Figure 2 Furthermore, the light-incident surface of the lens element 2 is provided with a cylindrical emission groove 24, which is used to place LED beads. By providing the emission groove 24, the light emitted by the LED beads can be fully integrated and emitted through the lens element 2, thereby improving light utilization.

[0026] Reference Figure 3 The lens element 2 is detachably connected to the headlight body 1. Specifically, the lens element 2 is provided with a connecting part 23, which is positioned towards the headlight panel 3. The connecting part 23 is provided with an elastic buckle 231. The headlight body 1 is internally fixed with a corresponding snap-fit ​​block 13. The elastic buckle 231 and the snap-fit ​​block 13 engage to achieve the connection and fixation between the lens element 2 and the headlight body 1.

[0027] Furthermore, the lens component 2 is integrally molded. By integrating all optical surfaces into a single component through a one-time injection molding process, production efficiency and lens consistency are effectively improved.

[0028] Reference Figure 2 and Figure 3 The lamp plate 3 is disposed in the mounting cavity 11. In this embodiment, a plurality of limiting ribs 14 are fixedly arranged in a circumferential array on the inner wall of the lamp body 1. The limiting ribs 14 extend along the length direction of the lamp body 1. The connecting part 23 of the lens 2 abuts against the surface of the lamp plate 3. The side of the lamp plate 3 facing away from the lens 2 abuts against the limiting ribs 14. The limiting action of the limiting ribs 14 and the connecting part 23 achieves the limiting of the lamp plate 3.

[0029] Furthermore, the connecting part 23 is provided with a mounting groove 232 surrounding its periphery, and a sealing ring is fitted inside the mounting groove 232. The sealing ring is interference-fitted with the headlight body 1 to achieve the connection sealing between the lens 2 and the headlight body 1, thereby improving the waterproof performance of the headlight and meeting the needs of outdoor use.

[0030] Reference Figure 1 Furthermore, to enhance the heat dissipation performance of the headlight, a heat sink 16 is fixedly installed on the outer surface of the headlight body 1, located near the headlight plate 3. The heat sink 16 accelerates the heat dissipation of the components within the headlight body 1, effectively improving the lifespan of the headlight plate 3. Preferably, the heat sink 16 is configured as a heat dissipation fin. The heat dissipation fin's full contact with the air further accelerates heat dissipation.

[0031] Furthermore, the headlight body 1 also includes a PCB board (not shown in the figure) and a battery (not shown in the figure). The battery is electrically connected to the PCB board to power the entire device. The lamp board 3 is electrically connected to the PCB board, and the PCB board can control the lamp board 3 to switch between different working states. The PCB board is connected to a USB / Type-C charging port for battery charging and a button switch for changing the working mode of the lamp board 3. A removable silicone plug 15 is provided on the headlight body 1 for waterproofing and dustproofing the USB / Type-C charging port and the button switch. In this embodiment, the button switch is located on the side wall of the headlight body 1, and the USB / Type-C charging port is located at the rear end of the headlight body 1.
