Abstract
Reflectors for a semiconductor light emitting device include a lower sidewall portion defining a reflective cavity. A substantially horizontal shoulder portion extends outwardly from the sloped lower sidewall portion. The horizontal shoulder portion has a circumferentially extending moat formed therein. An upper sidewall portion extends upwardly from the horizontal shoulder portion.
Claims24
A packaged semiconductor limit emitting device comprising:
- a reflector having a lower sidewall portion defining a reflective cavity, a substantially horizontal shoulder portion extending outwardly from the lower sidewall portion, the horizontal shoulder portion having a circumferentially extending moat formed therein and an upper sidewall portion extending upwardly from the horizontal shoulder portion, wherein an edge of the moat is configured to limit wicking of encapsulant material outwardly along the horizontal shoulder portion to allow formation of a convex meniscus of encapsulant material dispensed into the reflective cavity;
- a light emitting device positioned in the reflective cavity;
- and
- an encapsulant material in the reflective cavity and covering the light emitting device.
