SMALL-AND-MEDIUM-DIAMETER HIGH-LUMINOUS-INTENSITY LED ANNULAR-IRRADIATION SIGNAL LAMP

摘要

A small-and-medium diameter high-luminous-intensity LED annular-irradiation signal lamp. The lamp comprises: a multi-surface cylindrical heat dissipation body, an LED luminous unit being fixed to each outer plane of the multi-surface cylindrical heat dissipation body; an annular parabolic reflector component disposed on the periphery of the multi-surface cylindrical heat dissipation body, the annular parabolic reflector component being formed by multiple straight-strip-shaped parabolic reflector units, and the reflection surface of each straight-strip-shaped parabolic reflector unit reflecting light scattered by the corresponding LED luminous unit; and an annular convex lens disposed in an annular space defined by the reflection surface of the annular parabolic reflector component, light scattered by all the LED luminous units and light reflected by the annular parabolic reflector component being converged in the vertical direction and then diffused and emitted in the horizontal direction in an annular mode by the annular convex lens.
