Environmentally robust lighting devices and methods of manufacturing same
First Claim
1. A method of fabricating a lighting device, the method comprising:
- mounting a light emitting chip to a supporting surface of a substrate, the light emitting chip being a surface mount light emitting chip with or without an intervening submount, the substrate being configured to convey electrical power to the light emitting chip;
overmolding at least a portion of the supporting surface of the substrate, the overmolding not covering or contacting the light emitting chip, such that a gap is created between the overmolding and the light emitting chip;
encapsulating the light emitting chip with a silicone encapsulant; and
sealing an assembly including at least the silicone encapsulant and the light emitting chip using a light transmissive vinyl or acrylic layer.

Abstract
An illustrative lighting device comprises: a light emitting chip; a silicone encapsulant disposed over the light emitting chip; and a light transmissive vinyl or acrylic layer sealing an assembly including at least the silicone encapsulant and the light emitting chip. An illustrative method of fabricating a lighting device comprises: encapsulating a light emitting chip with a silicone encapsulant; and sealing an assembly including at least the silicone encapsulant and the light emitting chip using a light transmissive vinyl or acrylic layer. An illustrative method of fabricating a lighting device comprises: encapsulating a light emitting chip with a silicone encapsulant; and sealing an assembly including at least the silicone encapsulant and the light emitting chip by disposing a light transmissive plastic layer as a unit over the assembly.
