Patent number: 9477021Abstract: An energy efficient optical window has different optical properties when irradiated by solar light from front or back side of the window. The window is used to reflect most of the infrared light at summer times, leaving the interior cooler and to absorb most of the infrared light at winter times, making the interior hotter by heat transfer from the hot window pane. Mechanical reversal of the window, inside out, is used to apply the needed version for winter and summer. The window is coated with alternating thin metallic and dielectric layers that transmit most of the visible light while reflecting most of the infrared part of the spectrum when impinged by solar light on one side and transmit most of the visible light while absorbing most of the infrared part of the spectrum when impinged by solar light on the other side.Type: GrantFiled: March 14, 2013Date of Patent: October 25, 2016Assignee: KILOLAMBDA TECHNOLOGIES LTD.Inventors: Noam Gross, Ariela Donval, Doron Nevo, Moshe Oron

Patent number: 9467630Abstract: A system for facilitating a consumer's selection of customized color-changing lenses for eyewear, or windows, captures a digital color image of at least the face of the consumer and displays that color image to the consumer on a video display while superimposing a pair of lenses over the eyes. The display simulates the color of the superimposed lenses when made of a selected photochromic or thermochromic material. The color of the superimposed lenses is changeable, in response to consumer-controlled inputs, over a range between (a) an initial color for the lenses when subjected to at least one of (i) a first predetermined temperature and (ii) a first predetermined light condition, and (b) a final color for said lenses when subjected to at least one of (i) a second predetermined temperature higher than said first predetermined temperature and (ii) a second predetermined light condition brighter than said first predetermined light condition.Type: GrantFiled: October 7, 2013Date of Patent: October 11, 2016Assignee: KILOLAMBDA TECHNOLOGIES LTD.Inventors: Ido Dotan, Noam Gross, Ariela Donval, Doron Nevo, Moshe Oron

Patent number: 9310541Abstract: An optical power-limiting passive (self-adaptive) device and method for limiting optical power transmission in lenses and windows, using layers of different photochromic compositions that exploit the full solar ultraviolet (UV) and short visible light spectrum. While a typical single photochromic material is activated by a UV band of wavelengths, e.g. 340 to 380 nm, adding a layer of photochromic material that is activated by an additional band of wavelengths, e.g., 380 to 420 nm, allows the efficient use of a wider band of solar UV and short visible light, e.g., 340 to 420 nm, thus enhancing the photochromic response to solar light.Type: GrantFiled: May 13, 2013Date of Patent: April 12, 2016Assignee: KILOLAMBDA TECHNOLOGIES LTDInventors: Noam Gross, Ariela Donval, Ido Dotan, Moshe Oron, Doron Nevo

Patent number: 9268158Abstract: An optical window-filter includes a thermochromic material and a light absorbing material that can be bonded chemically. Absorption of light by the light absorbing material generates heat that causes phase transformation of the thermochromic material. A filter for an infrared imaging system has detectors sensitive to radiation in an infrared transmission spectrum. The filter includes a thermochromic material and a light-absorbing material. Absorption of high-power radiation in the infrared transmission spectrum by the light-absorbing material generates heat that causes phase transformation of the thermochromic material to attenuate the high-power radiation while transmitting substantially unaffected low-power radiation in the infrared transmission spectrum.Type: GrantFiled: August 5, 2013Date of Patent: February 23, 2016Assignee: KiloLambda Technologies Ltd.Inventors: Ariela Donval, Noam Gross, Eran Partouche, Doron Nevo, Moshe Oron

Patent number: 9223157Abstract: An optical limiter comprises a glass backing, a glass cover, and a layer of a phase changing material placed between said glass backing and said glass cover, the phase changing material comprising a transparent matrix having embedded particles of material that changes its optical properties due to temperature induced phase change of said material. The optical properties may change from transparent to reflective, from transparent to refractive or from transparent to scattering. The phase changing material is preferably at least one material selected from the group consisting of the elements Antimony, Bismuth, Cadmium, Lead, Tin and Indium and low-melting-point alloys of two or more of these elements.
