Publication number: 20150349147Abstract: A device having a broad-band, white incident angle range anti-reflection coating disclosed. The device includes a substrate having a first refractive index, at least one interference layer disposed on top of the substrate; and a gradient index optical layer. The gradient index optical layer has a gradient refractive index disposed on top of the at least one high index optical layer. The gradient index optical layer has a bottom refractive index at a bottom surface of the gradient index optical layer and a top refractive index at a top surface of the gradient index optical layer. The gradient refractive index of the gradient index optical layer decreases gradually from the bottom surface to the top surface. The at least one interference layer has a refractive index between the first refractive index of the substrate and the bottom refractive index of the gradient index optical layer.Type: ApplicationFiled: December 12, 2013Publication date: December 3, 2015Applicant: Raydex Technology, Inc.Inventors: Jingqun Xi, Frank W.

Publication number: 20150308661Abstract: At least one embodiment in the disclosure describes a high efficiency directional light engine. The light engine comprises a light emitter emitting light and a collimation lens. The collimation lens has a cone-shaped sidewall, a base surface and a curved top surface. The height of the cone-shaped sidewall is at least three times more than the diameter of the base surface. The light emitter is optically coupled to and disposed in close proximity to the base surface. One or more first reflection images of the light emitter result from first reflection of the light off a surface of the cone-shaped sidewall. The diameter of the light emitter is substantially close to the diameter of the base surface so that the light emitter and the first reflection images form a virtual point light source with minimal gap(s) or without any gap between the light emitter and the first reflection images.Type: ApplicationFiled: February 28, 2015Publication date: October 29, 2015Applicant: Raydex Technology, Inc.Inventor: Jingqun Xi

Publication number: 20130120986Abstract: At least one embodiment in the disclosure describes a high efficiency directional light engine. The light engine comprises a light emitter emitting light and a cone-shaped mirror having a base opening. The light emitter is disposed near or at the base opening. Light emitted from the light emitter is reflected off the cone-shaped mirror and results in one or more first reflection images. The light emitter occupies a substantial portion of the base opening such that the light emitter and the first reflection images forms a virtual point light source without a significant gap(s) between the light emitter and the first reflection images.Type: ApplicationFiled: May 23, 2012Publication date: May 16, 2013Applicant: RAYDEX TECHNOLOGY, INC.Inventor: Jingqun Xi

Publication number: 20130021669Abstract: There is herein described an optical filter. The optical filter includes a substrate and a plurality of at least four optical thin film layers. The optical thin film layers are disposed on top of the substrate. Each of the optical thin film layers has an effective refractive index different from effective refractive indices of the immediate upper and lower optical thin film layers. At least one of the optical thin film layers is a thickness tunable nano-feature layer. The nano-feature layer contains a plurality of flexible nano-features. At least one of the optical thin film layers is a dense layer.Type: ApplicationFiled: July 21, 2011Publication date: January 24, 2013Applicant: RAYDEX TECHNOLOGY, INC.Inventors: Jingqun Xi, Frank W.
