A Multi-Criteria Assessment Procedure for Outdoor Lighting at the Design Stage

Design Criteria for Tunnel Lighting

There are many mountains in the longitudinal center of Taiwan, which slow down transportation between the west and east in Taiwan. In order to solve this problem, Taiwan’s government decided to build a highway and an expressway between these two areas, which would include tunnels as part of the project because tunnels are more dangerous than the open road, how to safely enter, pass and leave tu...

Lumen Effectiveness Multipliers For Outdoor Lighting Design

Perhaps one of the most fascinating and important subjects to be addressed in our industry over recent years is the effect of lamp spectral distribution on visibility. In the past, it has been widely accepted that under virtually all circumstances where artificial light is used, lighting level calculations could ignore spectral effects. In IESNA and CIE practice, recommended lighting levels do ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
