Abstract: A lens for primarily forward distribution of light from a light emitter which has an emitter axis in a front-to-back centerplane. The lens has a base surface which is adjacent the emitter and forms a light-entrance opening, an inner surface which defines a light-receiving cavity and includes front and back regions extending from the light-entrance opening, and an outer surface which has front and back regions adjoined by a middle region. The back region includes a back portion configured for forward total internal reflection (TIR) of rearward light received from the inner surface. The back portion extends transverse to the front-to-back centerplane away from the base surface from positions which are closer to the base surface than the innermost cavity region and terminates with a distal end which is closer to the base surface than outermost positions of the front region. The back portion terminates laterally at positions closer to the front-to-back centerplane than lateral edges of the light-entrance opening and, in the front-to-back centerplane, the emitter axis is no farther from the back portion of the outer surface than from a back edge of the light-entrance opening.

Abstract: Solid state fixtures and packages are disclosed that include an optical element, such as an encapsulant, having an integrated indicator which indicates one or more characteristics of the package to a user, such as package orientation, polarity, chip-type, etc. The host optical element can be substantially symmetrical but for the indicator. Indicators can be additive, such as a bump, or subtractive, such as a hole. The indicator can be visible to the human eye, and/or can be machine detectable, such as by pick-and-place technology. Indicators can be formed by many processes including molding and laser ablation/imprinting, which is particularly suited for use with a hard host material.

Abstract: An LED light fixture a housing, a heat sink secured with respect to the housing, the heat sink has a base with front and back surfaces, and an LED arrangement mounted at the front surface of the heat sink The back surface of the heat sink is open to water/air flow thereover. The LED light fixture also includes at least one closed channel extending along the base and spaced therefrom for receiving wire connections for the LED arrangement. The at least one closed channel receives wiring extending to/from the second LED module. The LED arrangement may include at least first and second LED modules, the first LED module being proximal to the housing with the at least one closed channel receiving wiring extending to/from the second LED module. The first and second LED modules may be in end-to-end relationship to one another such that the second LED module is distal from the housing.
