In this paper, daylight harvesting is used to minimize the power consumption - required for indoor lighting using electric roller blind. Smart controller designed adjust based on preset light intensity position of blind’s stepper motor, and consequently blind opening better utilization entering room. If desired illuminance level (IL) not achieved any reason, smart adjusts LED circuit current bo...

Public lighting represents a large part of the energy consumption of towns and cities. Efficient management of public lighting can entail significant energy savings. This work presents a smart system for managing public lighting networks based on wireless communication and the DALI protocol. Wireless communication entails significant economic savings, as there is no need to install new wiring a...

Lighting is a fundamental and important process in the 3D animation pipeline. Conventional lighting workflow is time-consuming and labor-intensive. A user must fiddle with a range of unintuitive parameters one by one for a large set of lights continually to achieve the desired effect. LightShop, introduced here, provides the user with an intuitive and interactive interface employing the paradig...

We propose a lighting system which adjusts lighting colors. The lighting system adjusting colors is a system that provides required illuminance and lighting color at an appropriate location. This system consists of many intelligent lighting with RGB fluorescent lamps, many chroma sensors and an electric power meter. These equipments are connected to a network. The chroma sensor can measure the ...

The reports presented by consulting firms show that annual energy costs generated by 340 million streetlights are expected to reach $23.9 to $42.5 billion by 2025. Those numbers reveal a motivation behind the research aiming at optimizing outdoor lighting energy efficiency. They show that even a small unit improvement can yield large benefits due to the effect of scale. The development of solid...

In this work we present an improved rendering algorithm for the planning of stage lighting using photon mapping, since existing software implements algorithms that do not suit the lighting workflow in a theatre adequately. During theatre lighting, positional changes of light sources are occuring rarely compared to intensity and color changes: Once a light is positioned and aimed correctly, many...

Minimizing energy usage and increasing occupant comfort are the two primary objectives of intelligent and eco-friendly buildings. Energy savings of up to 70%, combined with significant occupant productivity gains are possible via the application of wireless sensor and actuator networks (WSAN). Despite the increasing interests in WSAN-based wireless intelligent lighting control, no prior survey ...

Current office lighting recommendations stress the importance of vertical surface illumination over horizontal desktop illumination for VDT work, where the occupant is primarily in a “heads up” position. We investigated this recommendation by creating two very different lighting conditions in two workstations in a mock-up open-plan office space. One workstation was provided with conventional, d...
