DETAILED DESCRIPTION

[0022] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0023] The utility model provides a headlight with a reflective bowl 200, which is mainly used in non-motor vehicles such as bicycles, scooters, and electric vehicles. Figure 1-4 As shown, the headlight includes a lamp frame 100, on which a lighting lamp, a reflective bowl 200 and a lens 300 are arranged. The lens 300 is located in front of the reflective bowl 200, and the top of the reflective bowl 200 has a notch. The light emitted by the lighting lamp will not be reflected by the reflective bowl 200 to the lower end of the lens 300 and refracted upward. The reflective bowl 200 can reflect the light to the upper end of the lens 300, so that this part of the light can be refracted downward through the lens 300. The reflective bowl 200 with a notch at the upper end can allow more light to pass through the lens 300, and can reduce the light refracted upward, thereby improving the brightness of the headlight and avoiding direct exposure to the eyes of people in front, thereby improving driving safety. The cross-section of the reflective surface of the reflective bowl 200 is semicircular, and the reflective surface is below its central axis. The semicircular reflective bowl 200 below the central axis can not only reduce the light emitted by the lighting lamp from being reflected to the lower end of the lens 300, and prevent more light from being refracted through the lower end of the lens 300 and deviating upward to form higher light, but also ensure the upper and lower widths of the light irradiated on the lens 300, thereby increasing the width of the light refracted by the lens 300 and making the illumination range larger.

[0024] like Figure 4 As shown, the lens 300 has a light incident surface 310, and the lower half of the light incident surface 310 is tilted forward from top to bottom. The lens 300 has a light-gathering effect, and the light incident surface 310 tilted forward from top to bottom increases the incident angle of the light, thereby increasing the refraction angle of the light, so that the refracted light is deflected downward, further reducing the light directly hitting the front human eye, thereby improving the safety of the formation.

[0025] like Figure 2 As shown, the lamp holder 100 includes a lamp holder 110 and a bracket 120. A circuit board 400 is arranged in the lamp holder 110. The illuminating lamp is mounted on the circuit board 400. The circuit board 400 has a first positioning hole 410. The reflector 200 has a first positioning column 210 inserted into the first positioning hole 410. The first positioning column 210 cooperates with the first positioning hole 410 to position the reflector 200 on the circuit board 400. The bracket 120 abuts against the reflector 200. A second positioning hole 420 is arranged on the circuit board 400. A second positioning column is arranged on the lamp holder 110. The circuit board 400 cooperates with the second positioning column through the second positioning hole 420 to be fixed. The bracket 120 is fixed on the lamp holder 110. The reflector 200 is located between the bracket 120 and the circuit board 400 to stabilize the reflector 200.

[0026] The bracket 120 is provided with a fixing portion 121, and the lamp holder 110 is provided with a fixing hole. The fixing portion 121 is fixed in cooperation with the fixing hole by means of a screw 122, so that the bracket 120 is fixed to the lamp holder 110. The fixing hole has an internal thread, and the fixing hole can be directly provided at the bottom of the lamp holder 110. In other optional embodiments, a fixing column can also be provided at the bottom of the lamp holder 110, and the fixing hole is located on the fixing column.

[0027] The bracket 120 is provided with a cavity 123 , the inner wall shape of the cavity 123 is matched with the outer wall shape of the reflective bowl 200 , and the reflective bowl 200 is embedded in the cavity 123 , so that the reflective bowl 200 can be protected and stabilized.

[0028] The lamp holder 100 is provided with a lampshade 500, and a decorative piece 600 is provided between the bracket 120 and the lampshade 500. The decorative piece 600 is integrally formed, and the integrally formed decorative piece 600 is easy to install and not easy to fall off. A mounting hole 610 is provided on the decorative piece 600, and the lens 300 passes through the mounting hole 610. The bracket 120 is provided with a limiting structure 124, and the lens 300 is abutted against the bracket 120 through the limiting structure 124 and the decorative piece 600. The decorative piece 600 not only plays a decorative role but also can stabilize the lens 300 to prevent the lens 300 from being misplaced and shaking. The decorative piece 600 is snap-fitted and fixed to the bracket 120.

[0029] The light-emitting surface of the lampshade 500 is a curved surface 510, and the curvature of the light-emitting surface is to For example The lampshade 500 with a relatively large arc surface 510 can reduce the blocking of light, so that more light is emitted downward.

[0030] The lampshade 500 is provided with a slot 520, and the lamp holder 110 is provided with a buckle 111, and the buckle 111 is snapped into the slot 520, so that the lampshade 500 and the lamp holder 110 are fixed together. The lower edge of the lampshade 500 has a mounting portion 530, and the upper edge of the lamp holder 110 has a groove 112. The mounting portion 530 is mounted in the groove 112 and sealed with a sealant, so that the lampshade 500 is more firmly mounted on the lamp holder 110 and plays a waterproof role. The lamp holder 110 is provided with a wire outlet hole 113, which is convenient for the circuit board 400 to be connected to the power supply. After the assembly is completed, the wire outlet hole 113 is sealed with a sealant.
