    Abstract: A LED lamp for use in an existing light fixture may be used in either a base-up or a base-down orientation. The lamp includes an at least partially optically transmissive enclosure. A LED assembly is located in the enclosure and emits light when energized through an electrical path. A heat sink dissipates heat from the LED assembly where the heat sink is connected to the enclosure such that the lamp has a longitudinal axis that extends from the heat sink to the enclosure. A reflector reflects light along the longitudinal axis of the lamp. The reflector may be oriented to reflect light either toward or away from the heat sink.

    Abstract: A lens for distribution of light from a light emitter. The lens has thick and thin wall portions between inner and outer lens surfaces. The thick wall portion(s) are at least twice as thick as the thin wall portion(s). At least one of the inner and outer surfaces has a texturing for diffusion of emitter light passing therethrough. The lens may include at least one interface between two materials with different indices of refraction. At least one surface of the interface may have a texturing for diffusion of emitter light passing therethrough. And, a method for manufacturing of the lens by forming a lens region with a textured surface portion by injecting the thermoplastic elastomer into an injection-molding cavity defined by a shape-forming configuration with a texturing in at least one area of the cavity. The shape-forming configuration is configured to shape a thermoplastic elastomer into such thickness that the set elastomer retains the texturing.

    Abstract: An LED light fixture including a housing, a heat sink secured with respect to the housing and an LED illuminator secured with respect to the heat sink. The heat sink includes central and peripheral portions. The central portion has an LED-supporting surface and forward, rearward and lateral sides, the LED illuminator being at the LED-supporting surface. The peripheral portion extends laterally from the lateral sides. The central portion of the heat sink has downwardly-extending shield members at the lateral sides thereof configured and dimensioned to block illumination in a direction opposite the LED illuminator. In embodiments where the optical member is configured for directing emitter light predominantly toward the forward side, the central heat-sink portion has a downwardly-extending shield member at the rearward side thereof configured and dimensioned to block rearward illumination.

    Abstract: A LED lighting device includes a temperature sensitive component having a temperature limit. A driver controls current delivered to the at least one LED and includes a temperature sensor for determining a temperature of the driver. A controller stores a correlated temperature limit of the driver, the controller controls the driver to reduce the current delivered to the LEDs when the correlated temperature limit is reached. The correlated temperature limit is the temperature of the driver when the temperature of the temperature sensitive component reaches its temperature limit.
