Substrate based light emitter devices, components, and related methods
First Claim
1. A light emitter device comprising:
- a substrate;
at least one light emitter chip on a first side of the substrate, wherein the substrate comprises a recessed portion disposed below a level of the light emitter chip;
a layer of phosphor-containing encapsulant disposed over the at least one light emitter chip; and
a non-reflective, external side wall forming an outer surface of the device, the side wall being at least partially disposed in the recessed portion of the substrate, wherein a first portion of the side wall is disposed above a height of the light emitter chip, wherein a second portion of the side wall is disposed below a level of the light emitter chip, wherein the first portion of the side wall contacts the layer of phosphor-containing encapsulant, and wherein the side wall is spaced apart from the light emitter chip by the layer of phosphor-containing encapsulant thereby retaining the layer of phosphor-containing encapsulant.

Abstract
Substrate based light emitter devices, components, and related methods are disclosed. In some aspects, light emitter components can include a substrate and a plurality of light emitter devices provided over the substrate. Each device can include a surface mount device (SMD) adapted to mount over an external substrate or heat sink. In some aspects, each device of the plurality of devices can include at least one LED chip electrically connected to one or more traces and at least one pair of bottom contacts adapted to mount over a surface of external substrate. The component can further include a continuous layer of encapsulant disposed over each device of the plurality of devices. Multiple devices can be singulated from the component.

17. A light emitter device comprising:
-
a ceramic substrate; at least one light emitter chip on a first side of the substrate, wherein the substrate comprises a recessed portion disposed below a level of the light emitter chip; a layer of encapsulant disposed over the at least one light emitter chip; and a non-reflective, external side wall forming an outer surface of the device being spaced apart from the light emitter chip by the layer of encapsulant for retaining the layer of encapsulant, the side wall being at least partially disposed in the recessed portion of the substrate, wherein a first portion of the non-reflective side wall is disposed above a height of the light emitter chip, and wherein a second portion of the non-reflective side wall is disposed below a level of the light emitter chip.
