Abstract
A transmissive optical element includes a transparent plastic member, such as a shell or a dome-shaped shell, including a phosphor pattern dispersed therein that can produce an indicia. The transmissive optical element may be combined with a semiconductor light emitting device, a mounting substrate, an encapsulant and inner and/or outer coatings.
Claims24
A transmissive optical element comprising:
- a shell that comprises a transparent plastic including phosphor nonuniformly dispersed therein to produce an indicia in the shell.
A transmissive optical element comprising:
- a transparent plastic member including phosphor nonuniformly dispersed therein to produce an indicia in the transparent plastic member.
A transmissive optical element comprising:
- a transparent plastic member including a phosphor pattern therein.
A light emitting device comprising
- a light emitting diode configured to emit light;
- and
- a transmissive optical element comprising a patterned phosphor wherein the phosphor interacts with light from the LED.
