i Abstract Nowadays, with increasing concern on environmental protection, energy crisis, and quality of life, in the context of the lighting industry, Solid-state Lighting (SSL) is considered as the next generation green lighting source, following the conventional lighting sources (like incandescent bulbs and fluorescent lamps). As a type of SSL, High Power White Light-emitting diodes (HPWLEDs)...

Street lighting systems are one of the key infrastructures of a city and are important for safe driving and safety of the pedestrians. Also, owing to the large number of lamps, street lighting accounts to high energy consumption and thus a significant cost to the utilities. Smart street lighting solutions enable control, monitoring and automatic fault detection, transforming these systems into ...

Here we describe the use of high-dynamic range lighting techniques to improve the rendering quality of real-time medical simulation systems. Specifically we show our method of extracting the lighting information from an actual endoscopic light probe used for surgery and how we apply this lighting information into a real-time rendering system based on OpenGL and using Shaders to improve the real...

This work presents an electronic board for driving and control of High Intensity Discharge (HID) lamps and Light Emitting Diode (LED) lamps. The proposed electronic board is able to drive HID or LED lamps by means of a reconfigurable output. This feature allows using the ballast in lighting systems that currently use traditional discharge lamps, as well as keeping the same ballast when discharg...

This paper reports the result of an investigation on the potential energy saving of the lighting systems at selected buildings of the Universiti Tenaga Nasional. The scope of this project includes evaluation of the lighting system in the Library, Admin Building, College of Engineering, College of Information Technology, Apartments, and COE Food court of the university. The main objectives of th...

This chapter seeks to explore the development of an ambient intelligent dance space. In particular, the chapter proposes intelligent systems that use non-linear optimization as well as symbolic rule-based systems to adjust sound/music, on-stage lighting, and projected visual imagery in terms of movement and color to dynamically reflecting the dancer’s arousal state measured through physiologica...

This paper argues that analytical approaches (i.e., simulation) and inductive learning methods (i.e., neural networks) can cooperate to facilitate a daylight responsive lighting control strategy. Multiple hybrid controllers are designed to meet four control goals: enriching the informational repertoire of systems control operations for lighting (by inclusion of performance indicators for glare ...

Nowadays, energy saving is one of the most important factor to consider. Automated lighting systems are a solution for efficient use of lighting which forms a large part of world’s total energy consumption. However, today automated lighting solution when employed in indoor environments like homes and offices are not very effective. Since indoor environment have users with different and varying ...
