Specific embodiment
Below by way of specific embodiment, the invention will be further described.
Referring to figs. 1 to Fig. 8, a kind of LED automobile signal lamp, including base 10, lens board 20, circuit board 30 and lampshade 40.
The circuit board 30 is fixed on base 10 and is sticked and has light source, and the light source is LED array 11, and the base 10 is connected with wiring.Should
Lens board 20 is fixed on the light-emitting area of circuit board 30, and the lampshade 40 is covered on lens board 20 and is connected with base 10.The lens
Plate 20 is provided with an at least convex closure lens 50, constitutes the array of convex closure lens 50 corresponding with LED array.The convex closure lens 50 it is vertical
Incident ray deviation is set to constitute the light guide at arrow beam of light angle to direction, the horizontal direction is provided with some convex closure portions 51 so that incidence
The opposite deviation of light constitutes the light guide of wide beam angle.The light spot illumination figure of the convex closure lens 50 in reference picture 9, during its hot spot is
Between big, the spindle of narrowing toward each end.The convex closure portion 51 is the curvilinear plane to convex or convex.
