A Smart Lighting Management System with Satisfaction of User's Lighting Requirements
Shin, Dae-Sik ; Kim, Hoon ;
In this paper, we proposed a smart lighting management system controls the lighting efficiently to reduce energy consumption while satisfying user's lighting requirements. The proposed system considers the available daylight intensity and indoor light source to satisfy the lighting requirements of each user according to the work environment. In addition, for user convenience, we have developed different user interfaces for lighting control including local interface, and remote interface through internet or Bluetooth for personal computer as well as smart phones. The proposed system satisfies the lighting requirements of each user according to the corresponding work environment. The proposed smart lighting management system utilizes the lighting energy efficiently, and can be considered a significant contribution towards future green buildings.

Development of High Efficiency and High Power LED Package for Applying Silicone-Reflector Jeong, Hee-Suk ; Lee, Young-Sik ; Lee, Jung-Geun ; Kang, Han-Lim ; Hwang, Myung-Keun Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 9, 2013, Pages 1-5 Abstract
We developed high-efficient 6W-LED package with simple structure by applying Heat Slug and silicone-reflector. LED package was manufactured in sized multi-chip structure having thickness of achieved by bonding silicon-reflector with prepreg on top of the plate after implementing the reflector placed on copper substrate Half Etching by thickness of . The luminous flux, luminous efficacy, correlated color temperature, color rendering index and thermal resistance of developed LED was evaluated, and it verified the application of products by applying it to 120W-LED road luminaires through simulation. The luminous efficacy of LED package reached over 130lm/W, and it is possible to be manufactured into 120W-LED road luminaires using 18 packages. In addition, the simulation results showed average of horizontal illuminance and overall illuminance uniformity that is suitable for three-lane road.

Quatro Medalhas Brasileiras Na Olimpíada Cone Sul
Hoje, 20 de agosto de 2014, foi divulgado o resultado da Olimpíada Matemática do Cone Sul. A Olimpíada Cone Sul é uma competição internacional da qual países são representados por equipes de 4 estudantes que não tenham feito 16 anos de idade em 31 de dezembro do ano imediatamente anterior à celebração da Olimpíada. A Olimpíada este ano aconteceu no Uruguai.
O resultado brasileiro foi:
Pedro Henrique Sacramento de Oliveira – Ouro
Gabriel Toneatti Vercelli – Ouro
João César Campos Vargas – Prata
Andrey Jhen Shan Chen – Bronze
Parabéns a toda a equipe brasileira!!
