April 11, 2022, 1:48 a.m. Updated 35 {"title": ["", "A new LED lighting construct using remote phosphor technology"], "description": ["", "\nLED lighting units require an individual AC power input and drive system encompassing\nelectrolytic capacitors which overheat; their life expectancy is 2 to 3000 hrs. Secondly,\ninstalling current LED lighting solutions into elaborate architectural designs is limited by the\nnecessity to incorporate individual drivers and power inputs into each lighting unit.\nInstallations are time and labour intensive with the requirements of extensive and unattractive\nmains wiring and cable looms giving rise to limited design flexibility. Finally, reproducing\ncolours of various objects faithfully (i.e. colour rendering Index - CRI) and the ability to\neradicate unwanted \u2018stepping\u2019 when dimming are also attributes the lighting industry are keen\nto address.\nVexica aims to conduct a period of R&D to prove the technical and commercial potential of\ndesigning and developing a new LED lighting construct in order to address industry and\ncustomer concerns. Fundamental to the design is substituting the cumbersome external driver\nsystem for new on-board \u2018solid state\u2019 technology allowing up to 50 one metre LED lighting\nstrips to be powered by a single AC mains input. Further, Vexica propose developing circuitry\nwhich will enable the ability to dim using TRIAC dimming modules. Fundamental also will\nbe the design of a new type of plastic casing based on a unique proprietary mechanical\n\u2018linkable\u2019 system (like Lego) which will allow continuous unbroken shapes to be designed\nand installed quickly and at a cheaper cost. The internal profile of the mixing chamber will be\nre-designed using a new identified or formulated material which gives rise to superior light\nextraction through diffuse and homogenous reflection. The light-emission window is to be\ncoated with new remote phosphor technology for low glare, high luminous efficacy and\nenhanced colour rendering. This also addresses colour consistency delivering reliable\ncorrelated colour temperatures that are consistent to 2-3 MacAdam Ellipses.\n\n"], "extra_text": ["", "\n\n\n\n"], "status": ["", "Closed"]}
