Lighting Design & Specification

The lighting design needed to accentuate and celebrate this historic structure's arresting grandeur without washing out the ornate details, while also creating a functional and welcoming workplace. "The space was so gloomy the National Bank was not even sure it could be transformed into a modern workspace. Most people wanted to move out," said Principal Senior Architect at Architecture 49, Alexandre Sauve.

The study focused on the impact of Luminaire dirt depreciation (LDD) on average illuminance and light distribution projected onto the road for LED luminaires.  Producing generalized LDD characterizations for LED luminaires proved challenging due to the many designs available on the market.

 

 

Health Effects

LED lamps and displays appear to pose no direct adverse health effects among the general healthy population, concluded a just-published literature review. However, the review found that gaps exist in our understanding of potential LED health hazards, and other population groups may be at risk. For example, exposure to LEDs and other light in the late evening may affect our circadian rhythm. LEDs may also have specific effects on young children and the elderly. Among its findings, the review noted that…

 

 

Color rendering index

 

The Color Rendering Index is intended to be an objective index, measured on a scale from 0 to 100, that compares a light source to the light emitted by a source emitting perfect blackbody radiation...

 

 

LED Heat Sink

 

LED lights do not generate light in the infrared spectrum and are, in fact, both cooler and more efficient than incandescents. Unlike traditional light bulbs that typically convert less than 10% of electrical energy input into illumination, LED fixtures can convert up to 45% of electrical power input into light.

 

 

As a mainstay in architectural and emergency vehicle lighting, colour LEDs bring about intrinsic advantages such as durability and reliability, in addition to the possibility of delivering controlled “colour light performances.” In recent years, however, the evolving architectural and emergency vehicle lighting landscape has necessitated developing colour LEDs that can enable the most effective and optimized system design...

 

 

Over the past decades light has been used to diagnose disease, enable digital communication through fibre optics, and generate power through solar panels. Most recently, advances in solid state lighting has transformed the most commonplace source of light, the lightbulb. The latest LED technology is not only making lighting more sustainable but also allows unprecedented control of light quality, colour, intensity as well as the inclusion of data and computation that was unimaginable with incandescent or fluorescent lighting...

Users sometimes report measurement discrepancies for the same LED when measured on two different systems. This could arise either because of errors with the system or different levels of accuracies between the two systems. This section describes several common sources of equipment errors and provides suggestions to minimize those...

 

 

Some day the last leg of our communication networks might not depend on a modulated radio signal but on a modulated light signal from an LED bulb in a desk lamp or ceiling fixture. IEEE Senior Member Harald Haas has developed a visible light communication system he calls light fidelity, or Li-Fi, which relies on nanometer waves in the infrared and visible light part of the electromagnetic spectrum to transmit data generated by an LED bulb fitted with a microchip...

The American Medical Association (AMA) Council on Science and Public Health (CSAPH) has issued two reports related to nighttime lighting since 2012. The 2012 AMA Report CSAPH 4-A-12 report, Light Pollution: Adverse Effects of Nighttime Lighting, resulted in AMA Policy H-135.932, noting in particular the “need for further multidisciplinary research of occupational and environmental exposure to light-at-night”, the recognition of how interior lighting and the use of electronic media affect sleep disruption especially in children and adolescents, and the need for work environments operating in 24/7 fashion to have employee fatigue risk management plans in place. The IES supports the 2012 AMA Policy H-135.932. Read more: IES Report. . .
