Embodiment two:
the structure of the lens is different from that of the first embodiment, the broken line in fig. 7 is used as a dividing line, the lens 8 includes a light inlet portion 15 and a light outlet portion 16, the light inlet portion 15 is connected with the light outlet portion 16, light emitted by the light source is emitted after passing through the light inlet portion 15 and the light outlet portion 16 in sequence, wherein the light inlet surface of the light inlet portion 15 is circular, the light outlet surface of the light outlet portion 16 is circular, and all radial sections of the lens 8 are circular.
Specifically, the diameter of the radial section of the light inlet portion 15 gradually increases from bottom to top in fig. 7, so as to form a structure with an eight-shaped axial section, and further, in the section of fig. 7, the centers of the left arc and the right arc of the light inlet portion 15 are located on the extension line of the light inlet surface of the light inlet portion 15, that is, the centers of the arcs on both sides of any axial section of the light inlet portion 15 are located on the plane where the light inlet surface is located. The light-emitting portion 16 has an equilateral trapezoid shape in any axial section, that is, both sides of the axial section of the light-emitting portion 16 are straight lines, and the straight lines are tangent to arcs on both sides of the axial section of the light-entering portion 15.
In the prior art, as shown in fig. 6, the lens has a bud-shaped structure, as can be seen from the light reflection path of fig. 6, most of the light is concentrated to the middle part after being reflected by the lens to form a light spot, and part of the light is also present at the edge of the lens, which is the reason for causing the light spot and the uneven light, and the center of the lens where most of the light is concentrated is caused due to the structure of the lens, but part of the light is still scattered at the periphery of the lens, so that the uneven illumination light is caused.
In contrast, in the lens 8 structure of the present embodiment, as shown in fig. 13, which is a reflection condition of light from a light source in the lens 8, and fig. 12, which is a reflection condition of the light source in the light inlet portion 15, it can be seen that, since the light inlet portion 15 is arranged in an inverted "eight" shape, light with a low angle is emitted out of the lens 8 after being reflected at least once, and as shown in fig. 13, no matter light with a low angle or light without being reflected, the light distribution after being emitted out of the lens 8 is relatively uniform, and no obvious phenomenon is concentrated in a certain place, that is, the lens 8 structure of the present embodiment can make the emitted light more uniform, thereby effectively reducing the occurrence of a flare phenomenon. The two sides of the axial section of the light emitting portion 16 in this embodiment are arranged as straight lines and tangent to the two side arcs of the axial section of the light inlet portion 15, so that the light rays are not directly reflected by the light emitting portion 16, and if the light emitted by the light source is directly reflected by the light emitting portion 16, the phenomenon of light ray concentration in the prior art is easily formed; the tangential design of the light emitting part 16 and the light entering part 15 can ensure that the first reflection of the light rays emitted by the light source occurs in the light entering part 15, and the light rays which do not need to be reflected can directly exit the lens 8, so that the uniformity of illumination of the light rays which do not need to be reflected can be ensured, as shown in fig. 9; further, the light beam with a low angle, which needs to be reflected, reaches the right side through the first reflection at the left side of fig. 11, reaches the light emitting portion 16 through the second reflection at the right light inlet portion 15, and then exits the lens 8 after the third reflection at the light emitting portion 16, or directly exits the lens 8 after reaching the right light inlet portion 15 or the light emitting portion 16 through the first reflection at the left light inlet portion 15 of fig. 11. As can be seen from fig. 11, the angle of the light emitted by the light source is from low to high, and finally the emitted light is gradually diffused from right to left, that is, the light emitting surface of the whole lens 8 can be distributed in the same opposite direction as shown in fig. 10, and the combined light path diagram is shown in fig. 12, that is, the light reflected by the light inlet portion 15 can be distributed in all directions on the light emitting surface of the lens 8, and the light without reflection can be uniformly diffused out of the lens 8, so that the problem of light concentration can be well solved by combining the light inlet portion 15 and the light outlet portion 16, and the formation of light spots is weakened, as shown in fig. 13.
In addition, as shown in the light inlet portion 15 of the lens 8 in fig. 8, a concave hole may be formed for assembling a light source, so that the height of the concave hole is set to be shorter in order to ensure the reflection function of the lens 8, the light reflection route of the embodiment is not affected, and of course, the lens 8 may not be provided with a concave hole, so long as the light of the light source is emitted from the center of the light inlet portion 15.
The present invention is not limited to the preferred embodiments, but is intended to be limited to the following description, and any modifications, equivalent changes and variations in light of the above-described embodiments will be apparent to those skilled in the art without departing from the scope of the present invention.
