Part 1 in this 3-part series provided an overview of lighting for industrial workplaces, plus two major reasons why lighting matters. Having considered both the role of lighting in the workplace and its contribution to capital costs and overheads, here are nine factors to consider in the selection process…
At the end of 2017, the Nobel Prize for medicine went to three American researchers: Jeffrey C. Hall, Michael Rosbash and Michael W. Young. By isolating and investigating the “period” gene of the fruit fly, they were able to prove the existence of the “inner clock,” which controls the circadian rhythm of humans, animals and plants…
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.
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.
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…
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 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…
