Improving CQS, CRI and LO of the 5600K RP-WLEDs by Red-emitting Conversion Phosphor
In the few last decades, Light-emitting diodes (LEDs) is considered the newest solid-state lighting technique advancement in both industry and civil lighting. In this paper, we improve the Color rendering index (CRI), Color quality scale (CQS) and lumen output (LO) of the 5600 K remote-packaging white LEDs (RP-WLEDs) by the red-emitting conversion Sr2Si5N8:Eu2+ phosphor. The influence of the red phosphor concentration on the CQS, CRI, and LO are proposed and demonstrated by using Mie Theory with Mat Lab and Light Tools software. The results draw that CRI, CQS, and LO are significantly affected by the red phosphor concentration, which can provide a potential practical recommendation for manufacturing RP-WLEDs.

期刊介绍：
International Journal of Automation and Smart Technology (AUSMT) is a peer-reviewed, open-access journal devoted to publishing research papers in the fields of automation and smart technology. Currently, the journal is abstracted in Scopus, INSPEC and DOAJ (Directory of Open Access Journals). The research areas of the journal include but are not limited to the fields of mechatronics, automation, ambient Intelligence, sensor networks, human-computer interfaces, and robotics. These technologies should be developed with the major purpose to increase the quality of life as well as to work towards environmental, economic and social sustainability for future generations. AUSMT endeavors to provide a worldwide forum for the dynamic exchange of ideas and findings from research of different disciplines from around the world. Also, AUSMT actively seeks to encourage interaction and cooperation between academia and industry along the fields of automation and smart technology. For the aforementioned purposes, AUSMT maps out 5 areas of interests. Each of them represents a pillar for better future life: - Intelligent Automation Technology. - Ambient Intelligence, Context Awareness, and Sensor Networks. - Human-Computer Interface. - Optomechatronic Modules and Systems. - Robotics, Intelligent Devices and Systems.
