Abstract:
A lighting assembly includes a light source and a lens. The lens includes a light transmissive portion and an optic shield portion for blocking or redirecting at least a portion of light generated by the light source. The light source can include one or more light emitting diodes (LEDs). The optic shield can be painted on or otherwise applied to a portion of the lens. Alternatively, it can be integrally formed with the lens. The optic shield can be an opaque material for blocking light generated by the light source or can be a reflective material for reflecting light generated by the light source through the light transmissive portion of the lens. Methods for making an optic shield are also described.
Abstract:
A single board light engine includes an AC to AC step driver that selectively powers multiple LED segments by controlling tap points between the LED segments as the input voltage goes from zero crossover to maximum voltage and returns to zero crossover. The step driver may power a first LED segment, a second LED segment, both the first and second LED segments, or none of the LED segments depending upon the input voltage level. The LEDs within an LED segment may share a characteristic that differs from a characteristic shared by LEDs in another segment, which allows the LED fixture to provide a variety of lighting effects.
