Patent number: 10302275Abstract: A light transmissive structure includes a light transmissive substrate having first and second opposing faces and array of microprism elements on the first face. A respective microprism element includes at least one ring comprising a plurality of microstructure pyramids that is rotated randomly and/or pseudorandomly on the first face about an axis that is orthogonal to the substrate relative to at least one other microprism element. The light transmissive structure is configured to receive light from a light source facing the first face and distribute the light emerging from the second face in a 2D batwing distribution.Type: GrantFiled: December 16, 2014Date of Patent: May 28, 2019Assignee: Bright View Technologies CorporationInventor: Ken G.

Patent number: 9765949Abstract: A light distribution device includes a light transmissive substrate having first and second opposing faces and a plurality of substantially parallel linear prisms on the second face that extend in a longitudinal direction of the substrate. The light distribution device is configured to connect to a light assembly including a linear light source with the first face of the substrate facing the light source, with the linear prisms substantially parallel to a light source longitudinal axis and with and the substrate having a non-planar cross-sectional shape such that at least a major portion of the substrate is concave relative to the light source. When connected, the light distribution device is configured to receive light from the light source and distribute the light emerging from the second face of the substrate in a batwing distribution pattern in a plane perpendicular to the light source longitudinal axis.Type: GrantFiled: July 25, 2014Date of Patent: September 19, 2017Assignee: Bright View Technologies CorporationInventors: Bing Shen, Ken G. Purchase, Thomas A. Rinehart, Christopher B. McLaurin

Patent number: 9086521Abstract: Light transmissive structures include a light transmissive substrate that includes optical microstructures. The optical microstructures have a geometric feature that is configured to reduce glare in light transmitted through the light transmissive structure. Moreover, the plurality of optical microstructures also have a geometric feature that is configured to vary randomly and/or pseudorandomly across the light transmissive substrate so as to diffuse light transmitted through the light transmissive structure. Related fabrication methods are also described.Type: GrantFiled: March 29, 2012Date of Patent: July 21, 2015Assignee: Bright View Technologies CorporationInventors: Thomas A. Rinehart, Robert L. Wood, Ken G. Purchase

Patent number: 8974069Abstract: A diffuser is configured to diffuse radiation from multiple light sources. The diffuser includes a substrate having optical structures that exhibit both microvariations and macrovariations along the substrate. For example, an array of microlenses may be provided that include at least one feature that varies as a function of the spacing between the light sources. Lighting systems using these diffusers may also be provided.Type: GrantFiled: July 21, 2009Date of Patent: March 10, 2015Assignee: Bright View Technologies CorporationInventors: Ken G. Purchase, William R. LeFew, Robert L. Wood, Robert M. Soule, III

Patent number: 8263318Abstract: Microstructures are fabricated by impinging a radiation beam, such as a laser beam, through a substrate that is transparent to the laser beam, into a negative photoresist layer on the substrate. The negative photoresist layer may be subsequently developed to provide a master for optical and/or mechanical microstructures. Related systems, microstructure products and microstructure masters also are disclosed.Type: GrantFiled: December 1, 2010Date of Patent: September 11, 2012Assignee: Bright View Technologies CorporationInventors: Robert P. Freese, Thomas A. Rinehart, Robert L. Wood

Patent number: 8128257Abstract: An LCD can include a Compact Collimating Reflector (CCR), is configured to be located downstream in a light path from an LCD light source, where the CCR is configured to reflect light from the LCD light source to provide collimated light downstream from the CCR. A light diffusion film is located downstream from the CCR and is configured to receive the collimated light from the CCR. An LCD panel is located downstream from the CCR.Type: GrantFiled: February 8, 2008Date of Patent: March 6, 2012Assignee: Bright View Technologies CorporationInventor: Robert L. Wood
