Patent number: 9587802Abstract: An LED assembly that includes optics and optical arrangements for light emitting diodes (LEDs). In some embodiments, a reflector is provided within a void between the lens and the LED. This reflector can reflect light emitted by the LED in a non-preferred direction back toward the preferred direction. In other embodiments, an optical element is formed or otherwise provided in the lens cavity and shaped so that, when the lens is positioned above the LED, the refractor bends the emitted light in a preferred direction. In some embodiments, both a reflector and optical element are provided in the LED assembly to control the directionality of the emitted light. Such embodiments of the invention can be used to increase the efficiency of an LED by ensuring that generated light is being directed to the target area of choice.Type: GrantFiled: April 22, 2015Date of Patent: March 7, 2017Assignee: ABL IP Holding LLCInventors: Jie Chen, Craig Eugene Marquardt, Daniel Aaron Weiss, Daniel Vincent Sekowski, Yaser S.

Patent number: 8596826Abstract: Light engines that include a plurality of light sources each covered with an optic The optic includes a chamber that receives the light source. In one embodiment, tubes connect adjacent light sources. Coolant is introduced into the tubes and circulates into the chamber of each optic, thus removing thermal energy from the chamber. In other embodiments, the light engines include a heat sink provided with channels. Coolant may be introduced into one of the channels, and may then circulate into the chamber of each optic to remove heat generated by the light source from the chamber. The channels provide a fluid path for the coolant to move between the different optics.Type: GrantFiled: August 23, 2010Date of Patent: December 3, 2013Assignee: ABL IP Holding LLCInventors: Januk Aggarwal, Yaser S. Abdelsamed, Raymond C. Rice

Patent number: 8300323Abstract: Collimators and methods of making collimators. According to certain embodiments a collimator may be used with a light source, where the light source emits light along a light source axis. The base of the collimator may be angled such that the collimator refracts the light in a direction that is angled relative to the light source axis. There may also be provided methods for making a collimator. According to one method, a mold is first provided that produces an uncut collimator having an extended portion. The uncut collimator may be cut at an angle to produce a collimator with an angled base. In another method, there may be a mold with a base cavity, and a wedge may be inserted in the base cavity. The wedge forms a collimator with an angled base.Type: GrantFiled: February 23, 2010Date of Patent: October 30, 2012Assignee: ABL IP Holding LLCInventors: Stacy Hoch, Yaser S. Abdelsamed

Patent number: 7866855Abstract: A reflector (14) for a luminaire comprises a generally parabolic wall (28) having series of main right-angled prisms (16) and an interleaved series of transition prisms (18). The main and transition prisms have essentially the same shapes and follow the same overall curvature to control the illumination. The transition prisms transition into the main prisms by merging a peak of a transition prism into the valley between adjacent main prisms in a short transition zone (20). Thus, the transition zone has only a small effect on the overall lighting pattern.Type: GrantFiled: December 2, 2005Date of Patent: January 11, 2011Assignee: ABL IP Holding LLC.Inventor: Yaser S.

Patent number: 7850342Abstract: A luminaire reflector of the type that is dome-shaped and includes a flange at the bottom provides a modified a flange that alters the pattern or other effect of light trapped in the wall of the reflector and exiting through the flange. When the bottom surface of the flange is angled with respect to the horizontal, the light exiting the flange is spread and lifted. In accordance with another embodiment, the flange is provided with a colored layer to provide decorative effects to the light exiting the flange.Type: GrantFiled: December 2, 2005Date of Patent: December 14, 2010Assignee: ABL IP Holding LLCInventor: Yaser S.

Patent number: 6971772Abstract: Luminaire optical assemblies intended for pole-mounted and similar applications and capable of effective I.E.S. cutoff performance while exhibiting desirable light distributions even with vertically oriented lamping, the invention contemplates in primary embodiments light-transmissive reflector/refractor combinations typically formed of glass, acrylics and the like, uplight shielding and reflector assemblies of a variety of configurations being disposed within the reflector/refractor combinations to produce desired cutoff characteristics while preserving daytime appearance during nocturnal operation. In certain embodiments of the invention, uplight is controlled by the several variations of the uplight shielding and reflector assemblies to cause light-transmissive portions of the reflector/refractor combinations to subtly glow and thus produce a desired appearance while also producing cutoff characteristics necessary to reduce urban sky glow and glare.Type: GrantFiled: June 12, 2003Date of Patent: December 6, 2005Assignee: Acuity Brands, Inc.Inventors: Yaser S.
