A light assembly that includes a cover, a housing coupled to the cover, and a lamp base coupled to the cover. The light assembly also includes a first circuit board disposed within the housing. The first circuit board has a plurality of light sources thereon. A heat sink is thermally coupled to the light sources and is disposed within the housing. The heat sink includes openings therethrough. Each of the outer edges is in contact with the housing. The light assembly also includes an elongated control circuit board assembly electrically coupled to the light sources of the first circuit board and the lamp base. The control circuit board extends through the openings. The control circuit board has a plurality of electrical components thereon for controlling the light sources.

Solid state light assembly with control circuit

A light assembly includes a light source circuit board, a plurality of light sources disposed on the light source circuit board, a housing thermally coupled to the light source circuit board and a lens cap assembly comprising a lens cap and a heat dissipation layer. The heat dissipated layer distributes heat from the light source circuit board through the lens cap and external to the light assembly.

Light assembly with a heat dissipation layer

A light assembly that includes an elongated housing, a reflective parabolic cylindrical surface within the elongated housing having a focal line and an elongated cover coupled to the elongated housing. The light assembly also includes a plurality of light sources spaced apart longitudinally and emitting light toward the parabolic cylindrical surface. The parabolic cylindrical surface reflects light from the light sources out of the housing through the cover.

Solid state tube light assembly

A light assembly having an axis of symmetry that includes an enclosure comprising at least a base and a cover coupled to the base. The light assembly also includes a plurality of light sources disposed on a circuit board within the enclosure in a first ring having a center point aligned with the axis of symmetry. The light assembly also includes a reflector that has a first focal point within the cover and a plurality of second focal points disposed in a second ring coincident with the first ring.

Solid state light assembly having light sources in a ring

A light assembly that includes an enclosure, a circuit board having a plurality of light sources disposed within the enclosure, and a plurality of light redirection elements associated with a respective one of the plurality of light sources. Each of the light redirection elements directs light toward a common point within the enclosure.

Solid state light assembly having light redirection elements

A light assembly that includes a base, a housing extending from the base having a partial paraboloidal cross-sectional surface, a light-shifting element disposed within the housing, and a plurality of light sources coupled to the housing. The light sources generate light. The light assembly also includes an angular portion reflecting light from the light sources toward the parabolic cross-sectional surface so that the light reflected from the parabolic surface is directed toward the light-shifting element and light reflected from the light-shifting element is directed out of the housing after reflecting from the housing.
