Abstract: The present disclosure provides an LED retrofit lighting device. The LED retrofit lighting device includes a light emitting assembly, a mounting interface at a bottom portion of the light emitting assembly, a receptacle at a top portion of the light emitting assembly, the receptacle having a plurality of electrical contact points, and a control module detachably coupled to the receptacle. The LED retrofit lighting device is suitably sized to be completely enclosed within the chamber space of a decorative lighting fixture.

Abstract: A heat sink for a light emitting diode (LED) lamp assembly includes a core region having a lower end, an upper end, a first region configured to receive an electrical connector, a second region configured to receive at least one LED, and a plurality of longitudinal vanes extending outwardly from the core region, and an upper thermal ring intersecting with and supported by the vanes. The heat sink further includes webs formed between adjacent pairs of the longitudinal vanes, the webs collectively defining an auxiliary thermal ring, the auxiliary thermal ring substantially circumferentially surrounding in spaced relation the core region and disposed, as viewed in the longitudinal direction, between the upper thermal ring and the lower rim. Each of the longitudinal vanes defines a respective thermal notch formed on a vane surface facing an adjacent longitudinal vane, the thermal notch being in confronting relationship to a respective air low aperture.

Abstract: A solid state lighting device (100) including a heat sink (108) stamped from a single sheet (200). The heat sink (108) features a base portion (111) including a central light module receiving region (114) configured to receive a light module (102), a first set of arms (116) extending generally radially outwardly from a perimeter (P) of the base (111), a first set of transverse members (118) intersecting with the first set of arms (116), a first set of air flow apertures (120) defined by the base portion (111), the arms (116), and the transverse members (118), and a first set of radiating plates (122) having adjacent radiating plates separated by gaps. Each one of the radiating plates (122) is bent outwardly and extends transversely from a front face of a first arm (116) or first transverse member (118).
