Patent ID: 8092065

Claim:
A multi-function planar light source illumination lamp having a containing space, the multi-function planar light source illumination lamp comprising: a first lighting unit for generating a first light source arranged as a linear element; a second lighting unit for generating a second light source arranged as a punctual array; a light guide unit, disposed in the containing space, for providing the multi-function planar light source illumination lamp to generate a homogeneous planar light source, the light guide unit comprising: at least an exit surface for outputting the planar light source; a reflective layer; and a plurality of reflective structures, disposed in the reflective layer, for reflecting the first light source and the second light source to the exit surface; and a control unit generating a control signal for controlling the first lighting unit and the second lighting unit to generate a luminous flux of the first light source and the second light source; wherein the first light source and the second light source change an angle of reflection according to the plurality of reflective structures, and selectively generate a light intensity distribution outside of the illumination lamp according to the light guide unit.
