| Title: |
Optical System for a Light Emitting Diode with Collection, Conduction, Phosphor Directing, and Output Means |
| Abstract: |
An optical system with an LED light source utilizes a base with an
inverted conical shape to conduct light to a phosphor layer. The phosphor
layer emits light from both upper and lower surfaces. The base and a
substantially mirror image cap element facilitate efficient extraction of
the phosphor-generated light from the optical system so that the output
of the system is omni-directional light suitable for common lighting
applications. The system is very efficient in that nearly all the light
generated by the LED is transmitted to the phosphor layer, and nearly all
the light emitted from the phosphor layer is output from the system.
