Patent number: 10870244Abstract: A method for manufacturing of a lens for distribution of light from a light emitter. The method provides an injection-molding cavity defined by a shape-forming configuration with a texturing in at least one area of the cavity. A thermoplastic elastomer is injected into the cavity shaping a lens-region thickness of the elastomer. Such lens-region thickness is cooled and set prior to sinking of the elastomer such that the lens-region thickness retains the texturing of the shape-forming configuration forming a textured surface portion of the lens.Type: GrantFiled: January 31, 2018Date of Patent: December 22, 2020Assignee: IDEAL INDUSTRIES LIGHTING LLCInventors: Kurt Wilcox, Craig Raleigh, Corey Goldstein

Patent number: 9915409Abstract: A lens for distribution of light from a light emitter. The lens has thick and thin wall portions between inner and outer lens surfaces. The thick wall portion(s) are at least twice as thick as the thin wall portion(s). At least one of the inner and outer surfaces has a texturing for diffusion of emitter light passing therethrough. The lens may include at least one interface between two materials with different indices of refraction. At least one surface of the interface may have a texturing for diffusion of emitter light passing therethrough. And, a method for manufacturing of the lens by forming a lens region with a textured surface portion by injecting the thermoplastic elastomer into an injection-molding cavity defined by a shape-forming configuration with a texturing in at least one area of the cavity.

Patent number: 9523479Abstract: A lens for distribution of light from a light emitter having an emitter axis. The lens includes an outer surface and a total internal reflection (TIR) surface positioned outwardly of and around the emitter such that light received by the TIR surface is totally internally reflected toward the outer surface. The TIR surface has at least one recessed region extending away from the light emitter, thereby to increase amount of TIR and facilitate lateral diffusion of highest-intensity light in the middle of the light distribution. The lens may further include a base surface adjacent the emitter and an inner surface defining an inner cavity about the emitter axis. In such embodiments, the TIR is positioned and configured for total internal reflection of light received from the inner surface.Type: GrantFiled: January 3, 2014Date of Patent: December 20, 2016Assignee: Cree, Inc.Inventor: Corey Goldstein
