Abstract:
1. A side illumination solid-state lighting device, comprising: a light reflective cavity enclosed by an electrical power connector, a substantially transparent output window and a thermally conductive substrate, the output window having a first end mounted about a peripheral edge of a top surface of the electrical power connector and a second end mounted about a peripheral edge of a bottom surface of the thermally conductive substrate, wherein the electrical power connector and the thermally conductive substrate are disposed in substantially parallel relation to one another; a support post positioned along a center axis of the light reflective cavity; at least one semiconductor light emitting element mounted on a bottom surface of the thermally conductive substrate and positioned within the reflective cavity such that a forward light emitting path of the at least one semiconductor light emitting element is directed towards the electrical power connector; a reflective member positioned within the reflective cavity such that at least a portion of the light emitted from the at least one semiconductor light emitting element will be reflected by the reflective member and extracted through the output window; an electrical conversion member positioned above the thermally conductive substrate and external to the light reflective cavity; a thermal heat sink member positioned to enclose the electrical conversion member and in contact with a peripheral edge of the thermally conductive substrate; and a power line positioned within the support post to electrically connect the electrical conversion member to the electrical power connector.
