Example Embodiment
[0053] Fig. 3 is a schematic diagram of a light-emitting unit according to an embodiment of the present invention. 3, the light-emitting unit 300 of this embodiment includes a light-emitting diode light source module 310 and a lens structure 400, wherein the lens structure 400 is disposed on the light-emitting diode light source module 310. The lens structure 400 includes a lens body 410, and the lens body 410 has a light incident surface 412, a light output surface 414 and a reflective surface 416. The light incident surface 412 is opposite to the light output surface 414, and the reflective surface 416 has a conical shape and is connected between the light incident surface 412 and the light output surface 414. The area of the light incident surface 412 is smaller than the area of the light output surface 414, and the light output surface 414 is a concave curved surface.
[0054]In the aforementioned lens structure 400, the light incident surface 412 is a flat surface, and th...
