We propose an improved method to design freeform reflectors for architectural lighting: one for accent lighting and another for large area wall washing. The designed freeform reflectors effectively distribute light fluxes over the target surfaces, and generate appropriate illumination patterns for comfortable visual environments, which provides greater flexibility for lighting designs, allows m...

Architecture and design students are frequently required to establish suitable lighting conditions for the buildings and spaces they design as part of their studio courses. While lighting design guidelines are available, students find out quickly that lighting quality is a complex issue that cannot be assessed by simple equations or rules-of-thumb. Balancing the many and often contradictory asp...

Light is the foundation of visual perceptual process that initiates evaluation surrounding area. Linked to various aspects and rhythms body, light connects us both natural environment interior space. The perceiving assessing space for children adults with different viewing heights perspectives as well role facilitate this are key elements study. paper describes general lighting design strategie...

In accordance with the specifications for the design of the gas station lighting system, the original lighting system was transformed into the overall solar-powered LED lighting system. The original lighting was replaced by using the same illumination LED lamps. Calculations were made to determine the optimum tilt angle of solar components. Based on the reasonable LOLP rate, solar module and ba...

Theoretical methods are usually performed for ideal conditions to determine the illuminance and luminance but other design limitations should be considered in the real world. Also the visibility level is calculated by using background and target luminance under ideal conditions. In reality, there are many factors, which are very difficult to predict and include in lighting design equation. Huma...
