[0064] For ease of understanding, the specific structure of each component of the automobile headlamp module will be further described below in conjunction with the accompanying drawings.
[0065] 1. Lens
[0066] Such as Figure 5 , 6 As shown, the lens 40 is a plano-convex lens, including a planar incident surface 42 and a convex surface 41 for light to exit; the lens 40 is provided with a positioning convex ring 43 protruding outside the convex surface 41 on the side close to the incident surface 42 The rotation axes of the convex surface 41 and the positioning convex ring 43 coincide with each other; a transparent mirror is formed between the incident surface and the convex surface for light emission.
[0067] The lens 40 is made of high borosilicate optical grade glass.
[0068] Such as Image 6 As shown, the thickness of the convex surface 41 of the lens 40 is B, the front part with a thickness of B / 3 from the top of the convex surface 41 to the side of the positioning convex ri...
