Lighting Design

The Illuminating Engineering Society (IES) has published three new lighting standards: Lighting for Exterior Environments (RP-33-14), Lighting for Parking Facilities (RP-20-14) and Approved Method for Photometric Testing of Indoor Fluorescent Luminaires (LM-41-14). Lighting for Exterior Environments (RP-33-14) addresses design issues related to outdoor lighting. It also outlines the environmental considerations of outdoor lighting especially related [...]

I wanted to share one of my recent contributions to ELECTRICAL CONTRACTOR on the topic of considerations for selecting the right LED reflector lamp, focusing on distribution of light and why application efficiency is so important. Click here to read the article, which I hope you find useful.

Two more educational videos from Philips Lighting today. Back to basics … This video describes the lumen method and how it’s used to determine average light level. This video describes how to calculate light level at a given point by applying the inverse square law.

The Lighting Research Center has produced a new video, featuring director Mark Rea, proposing lighting value metrics that look beyond cost and lumens and focus on application needs.

Therapeutic lighting can be a prescription for better health, especially for seniors with dementia. Now, more and more-effective products are needed to implement the highly positive research results achieved to date. So says a panel of therapeutic-lighting experts assembled by the National Lighting Bureau and the Edison Report. Panelists pointed out that some of the [...]

This educational video by Philips Lighting describes how a luminaire delivers its light at what angles and at what intensity, and how this information is recorded on a photometric report and analyzed.

On November 12, Parsons The New School for Design and Philips will present Luminous Talks 3: The Changing Room, a symposium that addresses thought-provoking topics of importance to professionals who work in design disciplines including architecture and design, scientists and scholars who are making advances in the field, and the members of the public who [...]

Philips Lighting interviewed some of the international lighting community’s most innovative designers. The topic? Light. Check it out here.

The proliferation of solid-state light sources has highlighted the limitations of the CRI metric as a predictor that fully represents how people perceive color. This article in ARCHITECTURAL LIGHTING describes these limitations and efforts to create a new metric. Check it out here. In March 2013, the IES formed the Color Metric Task Group to [...]
