Abstract:
1. An optical module for use in a lighting fixture for providing illumination of a plane, the optical module comprising: a plurality of light emitting diodes (LEDs) mounted on a circuit board; a plurality of reflector cups, each reflector cup surrounding one of the plurality of LEDs at a narrow first end and a larger opening at a second end opposite the LED; and a lens cover comprising a plurality of molded lenses, each for covering one of the plurality of reflector cups, each of the plurality of molded lenses of the lens cover positioned at the second end of the reflector cups providing a refractor over the opening of each reflector, wherein each of the plurality of molded lenses are oriented to provide illumination towards a plane in a defined lighting pattern, the lens cover comprising two or more blocks of repeating lens patterns, each block comprising at least a first lens and a second lens having a configuration profile different from the first lens, each repeating lens pattern of the two or more blocks providing the same light distribution pattern, wherein each lens comprising one of four curvature configurations, two on the longitudinal plane and two on the transverse plane of the lens, the first lens having a profile comprising curvatures in a longitudinal direction of approximately 10 mm and approximately 60 mm in radius and having curvatures in a transverse direction of approximately 2 mm radius with an internal angle of approximately 110° at a front section, and approximately 70 mm radius at a mid-section and a approximately 2 mm radius at a tailing section with an internal angle of approximately 12°.
