Embodiment approach 1
[0059] Implementation mode one: if Figure 11 As shown, the present invention provides a lens 51a, and the structure of the lens 51a and the lens 51 is basically the same. Specifically, the wall surface of the lens 51a includes a light incident surface 511a, a light exit surface 514a, a first reflective surface 512a and a second reflective surface 513a located on both sides of the light incident surface 511a, a first reflective surface 512a connecting the first reflective surface 512a and a light exit surface 514a. The connecting surface 515a and the second connecting surface 516a connecting the second reflecting surface 513a and the light emitting surface 514a.
[0060] The structural difference between the lens 51a and the lens 51 is that the second reflective surface 513a includes a plurality of sawtooth structures 5131a arranged continuously, the two ends of each sawtooth structure 5131a extend along the up and down direction of the lens 51a, and each sawtooth structure 51...
Embodiment approach 2
[0062] Implementation mode two: if Figure 12 As shown, the present invention provides a lens 51b, and the structure of the lens 51b is basically the same as that of the lens 51. Specifically, the wall surface of the lens 51b includes a light incident surface 511b, a light exit surface 514a, a first reflective surface 512b and a second reflective surface 513b located on both sides of the light incident surface 511b, and a first reflective surface 512b connecting the first reflective surface 512b and the light exit surface 514b. The connecting surface 515a and the second connecting surface 516b connecting the second reflecting surface 513b and the light emitting surface 514b.
[0063] The structural difference between the lens 51b and the lens 51 is that several continuous sawtooth structures 5141b are arranged on the light emitting surface 514b, and the two ends of each sawtooth structure 5141b extend along the extending direction of the lens 51b.
Embodiment approach 3
[0064] Implementation mode three: if Figure 13 As shown, the present invention provides a lens 51c, and the structure of the lens 51c is basically the same as that of the lens 51. Specifically, the wall surface of the lens 51c includes a light incident surface 511c, a light exit surface 514c, a first reflective surface 512c and a second reflective surface 513c located on both sides of the light incident surface 511c, and a first reflective surface connecting the first reflective surface 512c and the light exit surface 514c. The connecting surface 515c and the second connecting surface 516c connecting the second reflecting surface 513c and the light emitting surface 514c.
[0065] The structural difference between the lens 51c and the lens 51 is that the light emitting surface 514c includes a plurality of sawtooth structures 5142c arranged continuously, and the two ends of each sawtooth structure 5142c extend along the up and down direction of the lens 51c. The light emitting...
