[0019] Implementation Method 1 like Figures 1-5 As shown, this application discloses a vehicle light, including a housing 10, a reflector 30, and a light-emitting component 20 disposed within the reflector 30. The reflector 30 is disposed within the housing 10. The light-emitting component 20 includes a circuit board 22, an LED lamp 23, and a first lens 21 covering the LED lamp 23. The first lens 21 includes a freeform surface 211 for increasing light utilization, and the freeform surface 211 has a plurality of convex surfaces 212.
[0020] The vehicle headlight disclosed in this application includes a first lens 21 that covers the LED lamp. The first lens 21 includes a freeform surface 211 having multiple convex surfaces 212. Covering the LED lamp 23 with the first lens 21 reduces light loss, and the multiple convex surfaces 212 adjust the diverging light into parallel or near-parallel light emitted outwards, further reducing light loss and improving light utilization, thereby improving lighting quality.
[0021] The outer casing 10 provides protection, the reflector bowl 30 reflects the light emitted by the LED lamp 23, and the circuit board 22 enables the LED lamp 23 to emit light. Preferably, the light-emitting component 20 is disposed at the bottom of the reflector bowl 30 via an annular cover 24, and the first lens 21 is disposed at the bottom of the reflector bowl 30, thus preventing the light emitted backward by the LED lamp 23 from being wasted. The first lens 21 is a high borosilicate lens, which is low in cost. The freeform surface is an asymmetrical surface, which improves the light reflection effect and increases the light utilization rate by 30%.
[0022] Implementation Method 2 In a preferred embodiment, such as Figure 1 and Figure 7As shown, the headlight also includes a second lens 40, which is disposed on the opening of the reflector bowl 30. Preferably, the second lens 40 is a polycarbonate lens, and includes an arcuate surface 41, a light-concentrating plate 42, and an annular seat 43. The arcuate surface 41 coincides with the center line of the freeform surface 211. The light-concentrating plate 42 is disposed at the upper end of the body of the second lens 40, and the body of the second lens is fixed to the opening of the reflector bowl 30 by the annular seat 43. Preferably, a light-concentrating pattern 31 is provided at the opening of the reflector bowl 30, and the second lens 40 is disposed at the light-concentrating pattern 31.
[0023] In the above embodiment, the second lens 40 performs a second adjustment on the light emitted by the LED lamp, expanding the illumination range. The polycarbonate lens is low in cost and has good performance. The arc-shaped surface 41 coincides with the center line of the freeform surface 211, enabling comprehensive secondary adjustment of the light emitted from the freeform surface 211 without the need for a thick second lens 40, thus reducing costs. The light-concentrating plate 42 reduces the upward emission of light from the second lens 40, preventing it from affecting the driver's view. The light-concentrating pattern 31 focuses the light scattered by the second lens 40, preventing excessive divergence and reducing the illumination and range of the light.
[0024] Implementation Method 3 like Figures 1-4 As shown, in a preferred embodiment, the vehicle headlight further includes a base 50, which is slidably connected to the housing 10. Preferably, the base 50 has a through hole 51 for mounting, and the center surface of the base 50 coincides with the center surface of the housing 10. Preferably, the housing 10 has a mounting groove 11 and a plurality of positioning holes 12, and the mounting groove 11 has a wire hole 111 communicating with the reflector bowl 30. Preferably, the mounting groove 11 is located at the rear end of the housing 10, and the plurality of positioning holes 12 are located around the mounting groove 11.
[0025] In the above embodiment, the base 50 facilitates the mounting of the vehicle lamp, and the through hole 51 secures the mounting of the base 50. The center surface of the base 50 coincides with the center surface of the housing 10, which makes the center of gravity more balanced and the vehicle lamp more stable. The mounting groove 11 facilitates the mounting of the housing 10, and the wire hole 111 facilitates the electrical connection of the circuit board 22 to external wiring. Multiple positioning holes 12 are arranged around the mounting groove 11, which helps to secure the housing 10.
[0026] In summary, the vehicle headlight disclosed in this application adjusts the light by using the free-form surface of the first lens 21 to convert the diverging light into parallel or near-parallel light emitted outward, thereby improving the light utilization rate. Furthermore, the light is further adjusted by the second lens 40 with the arc-shaped surface 41, which greatly improves the light utilization rate and thus enhances the lighting quality.
