DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

The light emitted by the LED light source is reflected in the positive light emitting direction and the side light emitting direction of the automobile respectively under the action of the reflective surface on the reflective unit 3-1. Since the emitted light is reflected by a single LED light source, the uniformity of the emitted light at different positions of the automobile reflector is poor, resulting in poor overall light emitting effect of the automobile lamp; at the same time, the reflective unit 3-1 in the automobile reflector includes a positive reflective surface 3-1-1 and a side reflective surface 3-1-2. When the positive reflective surface 3-1-1 emits light in the positive light emitting direction (X-axis direction) of the automobile, there is a side reflective surface 3-1-2 between two adjacent positive reflective surfaces 3-1-1 for reflecting light laterally, thereby causing a dark area of ​​a certain range between the reflected light of the positive reflective surface 3-1-1; at the same time, as Fig.12 As shown, the lateral light emitting direction of the reflector 1 is perpendicular to the front light emitting direction, so that the lateral light emitting range of the reflector 1 is determined by the size of the reflector 1, and the lighting effect of the reflector 1 is poor when viewed at a large angle exceeding the size of the reflector 1.

[0032] See attached Figure 3 As shown, the present embodiment discloses a new energy vehicle lamp with uniform light emission from the front side at a large angle, comprising a reflector 1, wherein the reflector 1 comprises a light emitting area 2 which is arranged in an arc shape on the outside of the reflector 1 and has a light emitting range angle greater than 90 degrees, an inner reflection area 3 which is arranged opposite to the light emitting area 2, an upper reflection area 4 and a lower reflection area 5 which are arranged opposite to each other in an upper and lower direction between the light emitting area 2 and the inner reflection area 3, and a light entrance area 6 for installing a light source is provided in the inner area of ​​the upper reflection area 4; further, in order to ensure the uniformity of light emission from the vehicle reflector 1 and to improve the overall light emission effect of the vehicle lamp, in the present embodiment, a light emitting area 6 is provided in the light emitting area 6; 2 and the internal reflection area 3, a reflection blending space 7 connected to the light entrance area 6 is formed, and the reflection blending space 7 is located between the light entrance area 6 and the internal reflection area 3; part of the light from the light source enters the reflector 1 through the light entrance area 6 and then diffuses through the reflection blending space 7 and then is emitted to the internal reflection area 3; at the same time, the reflection blending space 7 is also located between the internal reflection area 3 and the light exiting area 2, and makes the internal reflection area 3 reflect part of the light toward the reflection blending space 7 and then emit it from the light exiting area 2; when in use, part of the light passing through the light entrance area 6 is directly emitted to the internal reflection area 3 and then is reflected by the internal reflection area 3 and then emitted to the light exiting area 2.

[0033] Further, such as Figure 3 and Figure 4 As shown, in order to eliminate the dark area existing in the stepped reflector 1 in the positive light emitting direction, the inner reflection area 3 in this embodiment includes at least one group of reflection units 3-1 distributed in an arc shape, and the reflection unit 3-1 includes a positive reflection surface 3-1-1 for reflecting light positively toward the headlight and a side reflection surface 3-1-2 for reflecting light sideways toward the headlight; the reflection units 3-1 are connected in sequence to form a step structure, and the side reflection surfaces 3-1-2 in adjacent reflection units 3-1 are connected to the positive reflection surface 3-1-1 in sequence from front to back; the positive reflection surface 3-1-1 is extended outward and makes the side reflection surface 3-1-2 connected thereto be inclined outward; specifically, as shown in FIG. Figure 3 and Figure 4 As shown, the rear end of the side reflection surface 3-1-2 in the reflection unit 3-1 of this embodiment is connected to the inner end of the regular reflection surface 3-1-1, and the front end of the side reflection surface 3-1-2 is connected to the outer end extension part of the regular reflection surface 3-1-1 in the adjacent reflection unit 3-1, so that multiple reflection units 3-1 are connected in sequence to form an arc-shaped reflection area 3; when in use, part of the light from the light source entering the reflector 1 through the light entrance area 6 is emitted to the side reflection surface 3-1-2, and the light is reflected by the inclined side reflection surface 3-1-2 and emitted to the light exit area 2; further, as Fig. 9As shown, a reflection angle α is formed between the side reflection surface 3-1-2 in the reflection unit 3-1 of this embodiment and the forward reflected light of the vehicle lamp, and α is greater than or equal to 3° and less than or equal to 20°; the reflection angle α on a plurality of reflection units 3-1 is gradually increased from the front to the back, and then the side reflection surfaces 3-1-2 on the reflection units 3-1 connected in sequence are set at different inclination angles, so that the side light emitting light of the side reflection surface 3-1-2 is gradually rotated and offset toward the front end to cover the side light emitting surface of the entire reflector 1;

[0034] Further, such as Figure 3 , Figure 5 and Figure 6 As shown, the reflection blending space 7 in this embodiment includes an upper reflection diffusion surface 14 located at the lower end surface of the upper reflection area 4, a lower reflection diffusion surface 15 located at the upper end surface of the lower reflection area 5, a right reflection diffusion surface 16 located at the right wall of the reflection blending space 7 and connected to the side reflection surface 3-1-2 of the rightmost reflection unit 3-1, and a left reflection diffusion surface 17 located at the left wall of the reflection blending space 7 and connected to the regular reflection surface 3-1-1 of the leftmost reflection unit 3-1; specifically, as shown in FIG. Figure 3 and Figure 5 As shown, the lower reflective diffusion surface 15 in this embodiment is provided with a plurality of lower arc-shaped protrusions 18 arranged in an array; the lower arc-shaped protrusions 18 in this embodiment are extended from the inner reflection area 3 to the light emitting area 2, and the lower arc-shaped protrusions 18 are in a long strip structure, and one end of the inner side of the lower arc-shaped protrusions 18 is located between the positive reflection surface 3-1-1 and the side reflection surface 3-1-2 of a single reflection unit 3-1. The lower arc-shaped protrusions 18 in this embodiment are respectively arranged at acute angles with the positive reflection surface 3-1-1 and the side reflection surface 3-1-2, so that the lower arc-shaped protrusions 18 are extended from the reflection unit 3-1 to the light emitting area 2 at an angle; at the same time, as shown Figure 5As shown, in this embodiment, a first outer diffusion reflection surface 18-1 that is gradually bent to the left from top to bottom and a first inner diffusion reflection surface 18-2 that is gradually bent to the right from top to bottom are provided on the lower arc-shaped raised portion 18, so that part of the light from the light source entering the reflector 1 through the light entrance area 6 is reflected by the curved first outer diffusion reflection surface 18-1 and then diffused toward the rear end of the light exit area 2 or the regular reflection surface 3-1-1 of the reflection unit 3-1, thereby increasing the incident light of the regular reflection surface 3-1-1, thereby improving the light output quality of the reflector 1 and improving the lighting effect, and at the same time, part of the light is obliquely emitted toward the rear end of the light exit area 2 through the first outer diffusion reflection surface 18-1, thereby increasing the output light of the light exit area 2, and at the same time, part of the output light The light is emitted obliquely from the rear end of the light emitting area 2, thereby increasing the observation angle of the reflector 1, and thereby making the light emitting range angle of the light emitting area 2 greater than 90 degrees, and also having a good lighting effect when the reflector 1 is viewed at a large angle exceeding the size of the reflector 1; correspondingly, part of the light from the light source through the light entrance area 6 is diffused by the first inner diffusion reflection surface 18-2 to the side reflection surface 3-1-2, wherein the light is reflected and diffused by the curved first inner diffusion reflection surface 18-2, and the diffused light further increases the incident light of the side reflection surface 3-1-2, and also makes the light reflected by the side reflection surface 3-1-2 more evenly distributed and brighter, thereby improving the lighting effect of the reflector 1 when viewed from the side at a large angle.

[0035] Similarly, if Figure 6 and Figure 7 As shown, in the reflector 1 of this embodiment, a plurality of vertical arc-shaped protrusions 19 arranged in an array and perpendicular to the lower arc-shaped protrusion 18 can be provided on the upper reflective diffusion surface 14, and the vertical arc-shaped protrusion 19 is also arranged in a long strip shape and has the same structure as the lower arc-shaped protrusion 18; wherein, the vertical arc-shaped protrusion 19 in this embodiment is provided with a second inner diffuse reflection surface 19-1 which is gradually bent to the left from bottom to top and a second outer diffuse reflection surface 19-2 which is gradually bent to the right from bottom to top; similarly, part of the light from the light source passing through the light entrance area 6 is diffused through the second inner diffuse reflection surface 19-1 to the regular reflection surface 3-1-1, thereby making the incident light on the regular reflection surface 3-1-1 further The increase makes more light reflected from the regular reflection surface 3-1-1, and also ensures the uniformity of light emission from the regular reflection surface 3-1-1, thereby further improving the light emission quality of the reflector 1 on the regular reflection surface 3-1-1; the other part of the light is diffused and emitted to the front end of the light emission area 2 through the second outer diffusion reflection surface 19-2; the vertical arc convex portion 19 arranged perpendicular to the lower arc convex portion 18 further increases the emitted light from the light emission area 2 during reflection, and at the same time, part of the emitted light is emitted obliquely from the front end of the light emission area 2, thereby increasing the observation angle of the reflector 1, and thereby making the light emission range angle of the light emission area 2 greater than 90 degrees, and also having a better lighting effect when the reflector 1 is viewed at a large angle exceeding the size of the reflector 1;

[0036] like Figure 8 As shown, a plurality of parallel arc-shaped protrusions 23 arranged in an array and parallel to the lower arc-shaped protrusion 18 may also be provided on the upper reflective diffusion surface 14 in this embodiment. The parallel arc-shaped protrusions 23 are also in the shape of long strips and have the same structure as the lower arc-shaped protrusions 18. When the parallel arc-shaped protrusions 23 reflect light, the partial reflection direction of the light is the same as the partial reflection direction of the light on the lower arc-shaped protrusions 18. Therefore, compared with the vertical arc-shaped protrusions 19, the use of the vertical arc-shaped protrusions 19 can make the light output quality of the reflector 1 better.

[0037] Furthermore, if Figure 3 As shown, the regular reflection surface 3-1-1 in this embodiment is an arc-shaped inner concave surface 8 that is gradually bent forward from top to bottom; and the middle end of the horizontal cross section of the arc-shaped inner concave surface 8 is bent backward to form an arc shape; further, as Figure 4 As shown, the arc-shaped inner concave surface 8 in this embodiment is provided with a plurality of patterned surfaces 9 distributed in an array and arranged in an arc-shaped outer convex structure, and a plurality of patterned surfaces 9 are arranged on the arc-shaped inner concave surface 8, so that the light incident on each position of the arc-shaped inner concave surface 8 is diffusely reflected by the patterned surface 9 with an arc-shaped outer convex structure during reflection, so that the light is further diffused through the patterned surface 9, so that the reflected light is dispersed more evenly, so that the light is distributed more evenly when emitting light, thereby further improving the light emission uniformity of the reflector 1.

[0038] Further, such as Figure 3 , Fig. 9 and Fig.10 As shown, the side reflection surface 3-1-2 is a vertical plane 10 arranged vertically, and a plurality of long arc-shaped raised surfaces 11 are arranged side by side from top to bottom on the vertical plane 10. The long arc-shaped raised surfaces 11 are in a convex arc structure, so that the side reflection surface 3-1-2 can realize reflection while the light is diffusely reflected under the action of the long arc-shaped raised surfaces 11, thereby making the light dispersion more uniform.

[0039] Furthermore, Figure 6As shown, in this embodiment, in order to facilitate the installation of the light source, a mounting cavity 12 is formed in the light entrance area 6 between the internal reflection area 3 and the reflection blending space 7 and has an intermediate unobstructed area, and mounting fixing parts 13 are provided around the mounting cavity 12; specifically, the mounting cavity 12 in this embodiment is used to install a control circuit board with a light source, and the control circuit board is covered and shielded in the mounting cavity 12. The number of light sources on the control circuit board in this embodiment is the same as the number of reflection units 3-1, and the light source is installed on the lower end surface of the control circuit board and is located at the front end of the positive reflection surface 3-1-1 of the reflection unit 3-1; in this embodiment, in order to increase the utilization rate of light, the lower end surface of the control circuit board can be made white, so that the light can be further reflected to other positions through the control circuit board, thereby improving the light output brightness of the reflector 1.

[0040] Further, such as Figure 3 As shown, the mounting and fixing portion 13 in this embodiment includes a supporting surface 20 opened at the upper end of the reflector 1 and connected to the mounting cavity 12, and a plurality of positioning pins 21 and threaded fixing holes 22 arranged on the supporting surface 20. The control circuit board for installing the light source can then be positioned through the positioning pins 21, and finally the circuit board can be fixed through the threaded fixing holes 22, thereby ensuring accurate positioning of the circuit board and high installation accuracy of the light source.
