Light emitting device package with frame and optically transmissive element
First Claim
1. A lighting device package comprising:
- a) a substrate;
b) a frame disposed on the substrate and having at least one passageway defined therein;
c) one or more light-emitting elements operatively disposed within the cavity; and
d) an optically transmissive system disposed on the frame and optically coupled to the one or more light-emitting elements;
wherein the frame has an inside surface that extends from a bottom surface of the optically transmissive system to a top surface of the substrate, and wherein the inside surface of the frame together with the bottom surface of the optically transmissive system and the top surface of the substrate define a cavity,wherein the cavity is at least in part filled with a light transmissive encapsulation material,wherein the passageway defined in the frame extends through the frame from the cavity to an associated outside port provided on a surface of the frame facing away from the substrate, andwherein the passageway enables fluidic movement of the encapsulation material between the cavity and the associated outside port.

Abstract
The present invention provides a lighting device package with one or more light-emitting elements operatively coupled to a substrate and a frame disposed at least in part around the one or more light-emitting elements. The frame and substrate define a cavity in which the one or more light-emitting elements are positioned, wherein this cavity can be substantially enclosed by an optically transmissive system. At least a portion of the cavity can be filled with an encapsulation material. The frame defines one or more passageways, wherein each passageway interconnects the cavity with the outside through an outside port. For example, the outside port can be accessible from the ambient when the lighting device package is in an assembled state, thereby enabling fluidic movement of the encapsulation material into and/or out of the cavity.

20. A lighting device package comprising:
-
a) a substrate; b) a frame disposed on the substrate and defining a cavity, the frame comprising one or more passageways defined therein, each of said one or more passageways fluidically coupling the cavity to an associated outside port; c) one or more light-emitting elements operatively disposed within the cavity; and d) an optically transmissive system disposed on the frame and optically coupled to the one or more light-emitting elements; wherein the cavity is at least in part filled with a light transmissive encapsulation material and wherein said one or more passageways enable fluidic movement of the encapsulation material, wherein the frame includes an inner surface facing the cavity, wherein the inner surface is optically reflective, and wherein the inner surface has mixed diffuse and specular reflective characteristics.
