Lighting Design & Specification

From 2012 to 2016, Earth’s artificially lit outdoor area grew by 2.2% per year, with a total radiance growth of 1.8% per year, reports an article published in the journal Science Advances...

 

 

 

Use of tubular retrofit lamps fitted into existing luminaires is worth considering as an economic next-step for achieving increased energy efficiency and longer in-service life over fluorescent bulbs...

 

 

 

A study conducted at Brigham and Women’s Hospital, a teaching affiliate of Harvard Medical School, shows that selectively reducing the amount of short-wavelength (blue) light emitted by a light reduced the alerting effects of typical indoor bedroom intensities before bed...

 

 

 

There has been a lot of discussion around the office lately about the relationship between energy management and power management. While sometimes used interchangeably, the distinction made between these two disciplines typically involves analysis of power distribution systems for energy cost saving (energy management) or for improvement of electrical reliability or availability (power management)...

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.

 

 

bridge with illuminated streetlightsThe 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...

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. . .
