    摘要： A lighting fixture (10) for mounting onto or into a structure (12) facing an illumination area (14). The fixture (10) includes a support member (20) configured for mounting into the structure (12) and including a front end-portion (22) having an edge (24) defining a light opening (16) and a back end-portion (26) recessed from the opening (16). The support member (20) and opening (16) have a centerline (28). A mounting board (18) is disposed at the back end-portion (26) and defines with the support member (20) an open space (30) extending to the opening (16). An LED arrangement (40) includes (a) LED emitter(s) (42) on the mounting board (18) for directing light (46) toward the opening (16), each emitter (42) defining an emitter axis (44), and (b) a lens (50A) for each emitter (42) at least one of which is off-centerline in a first lateral direction (32). The lens (50A) is configured for distribution of emitter light in off-axial direction across the open space (30) and passing through the opening (16) at an edge portion (25) that is off-centerline in the opposite lateral direction (33), thereby to widen the illumination angle (48) from the fixture (10) while having no more than minimal light directed onto the support member (20).

    摘要： A lighting apparatus includes a solid-state lighting circuit, a ballast connection port including first and second terminals and a filament-imitating impedance coupled between the first and a second terminals of the ballast connection port and to an input terminal of the solid-state lighting circuit. The filament-imitating impedance may be configured to transfer power at a nominal frequency of an output produced by the ballast and to provide an impedance between the first and second terminals of the ballast connection port that prevents shutdown of the ballast. In some embodiments, the filament-imitating impedance may vary with temperature, e.g., the filament-imitating impedance may be configured to imitate a temperature dependence of a fluorescent tube filament. The lighting apparatus may be included in a fluorescent lamp replacement lamp.

    摘要： A lens (50) for directing light from a light emitter (49) in a preferential-side off-axial direction with respect to the emitter axis (44). The lens (50) includes an emitter-adjacent base end (52) forming an opening (52A), an inner surface (54) extending from the base end (52) and forming a void (54A), an output-end surface (57) configured to direct light (46) toward the preferential side (35), and an outer lateral surface (57) configured for TIR to direct light toward the output-end surface (57), whereby substantially all light from the emitter (49) exits the output-end surface (57) predominantly toward the preferential side (35). Another aspect of this invention is a recessed lighting fixture (10) utilizing the inventive lens (50).

    摘要： A driver is connectable to an external power supply and configured to output a variable driving current for one or more loads, such as LEDs. A low intensity dimming module is operable to divert some or all of the driving current away from the LEDs when a user selects a very low level of light intensity so that the driver has a constant minimum load. The low intensity dimming module prevents performance issues that commonly affect drivers under light load conditions.
