Abstract

Solid state fixtures and packages are disclosed that include an optical element, such as an encapsulant, having an integrated indicator which indicates one or more characteristics of the package to a user, such as package orientation, polarity, chip-type, etc. The host optical element can be substantially symmetrical but for the indicator. Indicators can be additive, such as a bump, or subtractive, such as a hole. The indicator can be visible to the human eye, and/or can be machine detectable, such as by pick-and-place technology. Indicators can be formed by many processes including molding and laser ablation/imprinting, which is particularly suited for use with a hard host material.

First claim

1 . A light emitting device, comprising:
an optical element comprising an indicator.

2 . The light emitting device of claim 1 , further comprising a substrate;
wherein said optical element is on 90% or more of a top surface of said substrate.

3 . The light emitting device of claim 1 , further comprising a substrate;
wherein said encapsulant is on substantially all of a top surface of said substrate.

4 . The light emitti…
