[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figs. 1-3This utility model provides an emergency braking warning light, including a wireless brake light 1. The front end of the wireless brake light 1 is equipped with a lamp cover 2. The cross-section of the lamp cover 2 is corrugated, thereby forming multiple annular protrusions 3 around the center on the surface. The wireless brake light 1 is equipped with multiple warning light beads 4. When braking, a sensor is installed on the brake lever or brake cable to detect the braking action. For example, an acceleration sensor can detect the deceleration of the wheel to determine braking. The signal is transmitted wirelessly to control the warning light beads 4 to warn those behind, improving riding safety. After the warning light beads 4 emit light, it will shine on the multiple annular protrusions 3. The annular protrusions 3 will refract the light along the corrugated surface, expanding the light along the diameter of the lamp cover and increasing the brightness range.

[0023] Specifically, the lampshade 2 has a mounting hole in the center and a button 5 is installed thereon. The button 5 is connected to the switch control unit of the circuit board inside the wireless brake light 1. In this embodiment, the wireless brake light 1 is switched on and off by the button 5. It can be turned off to save power when there is sufficient ambient light.

[0024] Specifically, the warning light beads 4 are arranged in multiple rings on the inner side of the annular protrusion 3, and the warning light beads 4 in each ring are equally distributed around the center of the lamp cover 2. In this embodiment, the multiple rings of warning light beads 4 can cooperate with the multiple rings of annular protrusion 3 to form multiple evenly spaced lights that extend along the wave surface in each ring of annular protrusion 3, thereby improving the overall brightness.

[0025] Specifically, the warning LED beads 4 in adjacent rings are staggered; in this embodiment, the light is prevented from overlapping along the diameter of the lampshade 2, so that the light is fully distributed in a limited space.

[0026] Specifically, the ripples of the lampshade 2 increase in amplitude from the inside out; in this embodiment, the light can be extended outward to expand the illumination range.

[0027] Specifically, the size of the warning light bead 4 is the same as that of the ring, and the size increases from the inner ring to the outer ring. In this embodiment, the increasing ripples further increase the amount of light entering the outer ring, and the gradually expanding ripples refract light to expand the illumination range.

[0028] Specifically, the cross-sectional corrugations of the lampshade 2 are designed with uneven thickness, and the thickness tends to be greater at the crests than at the troughs. In this embodiment, the uneven thickness design, with the thickness tending to be greater at the crests than at the troughs, enhances the horizontal focusing of light as it spreads along the wave surface, which is beneficial for enhancing illumination brightness and increasing the illumination distance behind.

[0029] Specifically, the wireless brake light 1 is equipped with a fixing strap 6 on its rear side, and the fixing strap 6 is provided with a fastening adjustment screw; in this embodiment, the fixing strap 6 facilitates the fixing of the wireless brake light 1 to the rear of the bicycle, and the fastening adjustment screw is used for fixing.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] Working principle: Braking is determined by detecting wheel deceleration. Wireless signal transmission controls the warning light beads 4 to warn those behind, improving riding safety. The light emitted by the warning light beads 4 illuminates multiple annular protrusions 3. These protrusions refract the light along the wave pattern, expanding the light along the diameter of the lampshade and increasing the brightness range. The multiple rings of warning light beads 4 work in conjunction with the multiple rings of protrusions 3, forming evenly spaced light extending along the wave pattern in each ring, increasing overall brightness. The size of the warning light beads 4 is the same as the ring size, increasing from the inner to the outer ring. This increasing wave pattern further expands the light intake on the outer ring, and the gradually expanding wave refraction further widens the illumination range. The uneven thickness design, with the thickness at the crests being greater than at the troughs, enhances the horizontal focusing of the light near the crests as it extends along the wave pattern, thus strengthening the illumination brightness and increasing the rear illumination distance.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
