A 2020 CABA White Paper, Application of Wireless Power Transfer (WPT) in Smart Homes and Buildings provides an overview of WPT technology, as well as a market evaluation for the technology, including key global companies. Some potential applications of wireless charging to lighting include:

  1. Wireless charging of cell phones and other devices from desk lamps.
    WPT transmitters integrated into lamp bases could charge devices laid upon them.
  2. Reduced risk with electrical products installed near water. WPT eliminates power cords and wiring. Imagine more safely putting lights in sinks, bathtubs, showers and other areas near water. Both the transmitter and receiver/luminaire could be fully sealed against water.
  3. Potential for better and safer mobile battery-powered lighting, without electro-mechanical charging contacts.

CLTC Launches New Color Lab

The California Lighting Technology Center (CLTC) at UC Davis has established “The Color Lab” in collaboration with the Center for Mind and Brain. The new color lab will explore the impact of discrete color spectra on stress, mood, and alertness.

The California Lighting Technology Center (CLTC) at UC Davis has established “The Color Lab” in collaboration with the Center for Mind and Brain. The new color lab will explore the impact of discrete color spectra on stress, mood, and alertness.

A recurring question asked by building owners during human-centric lighting design is “which light colors should I use to optimize the space for the well-being of occupants?” Today, there is little data to support the use of specific light colors for increased wellness; however, with commercially available color-tuning lighting technologies, answers to this question and more are now being researched.

The Color Lab will be available to all UC Davis researchers and partners interested in studying the interactions between discrete spectra and humans. Partners from The Betty Irene Moore School of Nursing at UC Davis and the UC Davis College of Biological Sciences are already collaborating with the team on the circadian implications of discrete spectra via the Davis Circadian Protocol. This work is supported by Toyota-Boshoku America. More information is available here.

New DLC Whitepaper On Non-White Light Sources For Outdoors

There is growing scientific evidence that LED outdoor white light at night is devastating global insect and bird populations, in addition to potential negative human health impacts. A possible solution is to move back to non-white lighting, such as phosphor-converted amber and direct emission amber LED sources, outdoors.

There is growing scientific evidence that LED outdoor white light at night is devastating global insect and bird populations, in addition to potential negative human health impacts. A possible solution is to move back to non-white lighting, such as phosphor-converted amber and direct emission amber LED sources, outdoors.

The DesignLights Consortium (DLC) recently introduced the first version of its LUNA Technical Requirements. The policy offers a streamlined way to identify and select LED products that meet the efficacy thresholds necessary for inclusion on the DLC’s Solid-State Lighting (SSL) Qualified Products List (QPL) while also limiting sky glow and light trespass and helping to mitigate light pollution. LUNA sets performance requirements for specific categories of outdoor LED fixtures so that municipalities, energy efficiency programs, and other outdoor lighting decision-makers can better support their energy reduction goals and abide by dark sky policies and ordinances. LUNA will also help specifiers to fulfill the light pollution and trespass requirements of LEED and WELL building programs, and help projects follow application guidance in the joint International Dark Sky Association-Illuminating Engineering Society Model Lighting Ordinance.

A subset of the DLC’s SSL Technical Requirements, the LUNA V1.0 Technical Requirements apply only to white light LED outdoor products with correlated color temperatures (CCT) between 2200K and 3000K, and do not include non-white light (NWL) LED luminaires deemed appropriate for settings such as environmentally sensitive wildlife areas. During development and implementation of the first iteration of LUNA V1.0, stakeholders asked the DLC to consider allowing NWL LED sources, such as phosphor-converted- (pc-) amber and direct emission (de-) amber products, to be eligible for LUNA qualification.

This whitepaper provides an overview of the state of the science and current recommendations for NWL light sources in outdoor lighting applications, as well as why the DLC is not addressing NWL LED luminaires in LUNA, at this time. The paper suggests the next steps to address gaps in existing research, standards, and guidelines that would make qualification feasible in the future.

NEMA Published Recommendations For Replacing HID Lamps With LED Lamps

In February, 2022, NEMA published NEMA LL-10, Replacing HID Lamps with LED Lamps: Light Output Equivalency Claims. This document describes a method for claiming equivalency of LED lamps to the HID lamps they replace.

In February, 2022, NEMA published NEMA LL-10, Replacing HID Lamps with LED Lamps: Light Output Equivalency Claims. This document describes a method for claiming equivalency of LED lamps to the HID lamps they replace. The NEMA standard applies to omnidirectional lamps. (The equivalency for directional lamps is more complicated and requires simulation or mockups to establish). The intention is for manufacturers to use LL-10 when they prepare their equivalency claims.

Replacing high-intensity discharge (HID) lamps with light-emitting diode (LED) equivalents should be an easy and straightforward endeavor. However, currently, there are significant variations in the luminous flux (light output) of LED lamps claiming to be equivalent to a particular HID lamp wattage. When this happens, customer confusion and dissatisfaction can ensue and result in an unlevel playing field for manufacturers. NEMA provides value to the end-user and the manufacturing community with recommendations for when this scenario occurs.

New Lighting Designer Directory Published By inside.lighting

Last month, lighting industry news website, inside.lighting, published a new Lighting Designer Directory. To find out more about this new industry resource, I interviewed Al Uszynski, Editor & Publisher of inside.lighting.

Last month, lighting industry news website, inside.lighting, published a new Lighting Designer Directory. To find out more about this new industry resource, I interviewed Al Uszynski, Editor & Publisher of inside.lighting.

DS: When did you launch the Lighting Designer Directory on inside.lighting?

AU: We’ve been contemplating a lighting designer directory for a couple of years, but the work really started in late 2021. The debut of the Lighting Designer Directory was February 2022.

Our mission was to find a way to give a signal boost to architectural lighting designers while segmenting them from other “lighting design” professions that relate to live events, film, TV production, landscape installations and the design of custom light fixtures.  Try Googling “Lighting Designer in…” for your city and it’s often hard to find architectural lighting designers among all the different search results.

DS: How many lighting designers are in the database, currently?

AU: We take a firm-centric approach and not an individual-designer approach.  We have over 350 architectural design firms listed that represent over 1,000 individual architectural lighting designers throughout the U.S. and Canada.

DS: How should a lighting designer / firm get themselves added to your directory, if they’re not currently listed?

AU: Design firms should send us their firm information via the inside.lighting contact form.  Include a link to the firm website.  We’ll take a look at their online portfolio to ensure they provide architectural lighting design services.  Easy peasy – and we never charge designers for listings or links.

DS: Do you anticipate adding any search functionality around vertical specializations, such as healthcare, hospitality, industrial, retail, etc.?

AU: That is a cool suggestion but also one that might not create the differentiation that one would expect.  We anticipate that most firms would check the questionnaire box for each of those project types.  We provide links to each firm’s website, so their online portfolio can speak to their unique expertise.  In most states and provinces there are fewer than 15 listings, so it’s a manageable experience for the website visitor.

DS: How do you feel the response has been to the directory, from lighting designers and directory users?

AU: It’s been fantastic.  When we first launched the directory, we were flooded with inquiries from designers to tweak their listings, add their satellite office location, etc. – which we take as a good sign that there’s value to the design firms.  We continue to get several new designers per week requesting to be listed.  We received lots of positive feedback from the lighting design community at the recent LEDucation 2022 trade show and conference.

DS: Who do you think are the primary users of the directory? Building owners? Architects? Construction firms? Other?

AU: The main goal is to attract visitors who are seeking architectural lighting design services.  As inside.lighting has grown to over 50,000 visitors per month, we know that we get some good traffic from architects and end-users.  The real value will come over time as Google fully indexes the directory and starts pointing organic search traffic to the directory.

We predict that later this year when someone Googles “Lighting Designer in _______” that we will be a top search result just like we are currently the #1 result for “Lighting News,” “Lighting Industry Jobs” and “Lighting Agents in __________.”

DS: How do you see the directory evolving over time?

AU: We want to grow the directory size to make it even more useful.  We’d also like to add an Instagram link to each listing.  As social media consumers, we believe the best social platform for architectural design firms is Instagram.  Seeing the visuals of their finished work, or the videos of an installation in progress is the best way to capture the value that these awesome service professionals bring to their projects.

Thanks for the thoughtful questions – we really appreciate what LightNOW does and enjoyed the opportunity to connect!

IES BIM Committee Seeks Online Votes For Two Proposed Autodesk Revit Lighting Features

The IES BIM Committee is requesting help. Have you been unhappy with the process of documenting lighting in BIM software, specifically Revit? Do you wish there were features that the software had to make the lighting workflow more compatible with those of other trades?

The IES BIM Committee is requesting help. Have you been unhappy with the process of documenting lighting in BIM software, specifically Revit? Do you wish there were features that the software had to make the lighting workflow more compatible with those of other trades?

From a lighting specifier survey conducted last year, the IES BIM committee created a series of requests to Autodesk’s Revit Ideas forum. Users post requests; other users vote on the requests. Autodesk takes notice of posts that have a high number of votes, generally those with more than 100 votes.

The IES BIM Committee has taken all the feedback that they received from the survey responses and created a series of requests on the forum. Two posts have been on the forum for a while but haven’t received enough votes to attract Autodesk’s attention.

  1. Multiple Light Sources in a single Family, without nesting. This request was authored by IES BIM Committee member Matt Kincaid and addresses the fact that nesting is required for lighting families to have more than one light source. Nesting is problematic for aiming and photometric calculations. For more information, read Matt’s post and vote!
  2. Visibility Below Cut Plane In RCP. For many of us, it is helpful to see architectural elements, like furniture or step lights, that wouldn’t typically be shown on a Reflected Ceiling Plan as we lay out our designs. Currently, Revit doesn’t have a good way of showing that. There are workarounds, like making the cut plane close to the floor, but they all have their downsides. Allowing for visibility of elements below the cut plane would make it easier for us to see what we need without messy workarounds.

The IES BIM committee is requesting that interested specifiers click on the links above and vote for these ideas, as well as any other ideas there that you would like to have implemented.

New International Lighting Non-Profit Founded In Canada

The All Things Lighting Association (ATLA) has been founded as a non-profit organization to advance, support, promote, and contribute to innovation, science, and engineering in all fields of lighting, including architecture, health, horticulture, and entertainment.

The All Things Lighting Association (ATLA) has been founded as a non-profit organization to advance, support, promote, and contribute to innovation, science, and engineering in all fields of lighting, including architecture, health, horticulture, and entertainment. ATLA was founded with three goals:

  1. To provide ATLA S001, Standard Format for the Electronic Transfer of Luminaire Optical Data, and ATLA S001-A, Amendment to Standard Format for the Electronic Transfer of Luminaire Optical Data, Including JSON Specification, as freely-available standards for lighting industry adoption. ATLA S001 has been published as ANSI/IES TM-33-18 and (in Italian) UNI 11733:2019, and ATLA S001-A is a work product of CIE Technical Committee 2-92. If approved, ATLA S001-A will likely become a joint CIE/ISO standard. It is also under consideration by the IES as a successor to TM-33-18.
  2. To curate blog articles and other resources (such as bibliographies) on lighting research issues. Lighting research has become increasingly cross-disciplinary over the past decade or so, and it can be difficult for both researchers and lighting professionals to understand the broader scope. The articles are intended to examine specific issues and provide references to the literature that both support the presented information and offer a guide for more in-depth study. The initial postings are my blog articles from the last eight years, but peer-reviewed contributions from other authors will be welcomed.
  3. SunTracker Technologies has employed eleven university students and graduates over the past four years for its lighting-related research projects, as well as providing annual scholarships. SunTracker Technologies Senior Scientist, Ian Ashdown, has also been mentoring graduate students in a number of disciplines from North America, Europe, Africa, and India. ATLA will provide a framework to coordinate this work, including documentation, research resources, discussion, and networking, for students and others involved in lighting-related research.

New NEMA White Paper On The History, Proper & Inproper Uses of UGR

The National Electrical Manufacturers Association (NEMA) published NEMA LS 20001-2021, White Paper on Unified Glare Rating (UGR). This new white paper explains the original intent of UGR, its proper uses, and common misuses.

The National Electrical Manufacturers Association (NEMA) published NEMA LS 20001-2021, White Paper on Unified Glare Rating (UGR). This new white paper explains the original intent of UGR, its proper uses, and common misuses.

UGR is one of the few lighting metrics that practitioners use to model and design appropriate lighting to meet application and task visual needs. In the hands of a competent lighting designer, it can provide insight into visual comfort expectations when included as part of a complete lighting design because it incorporates room layout, luminaire layout, the task being performed, and surface reflectances.

However, improper use of the UGR approach can result in poor lighting design, poor luminaire design, and unintended glare. The NEMA white paper aims to prevent such misuse through education on the context of UGR and by demonstrating how erroneous use as a luminaire-specific qualification metric can lead to glare inaccuracies for lighting designs.

The audience for this paper includes lighting designers, luminaire manufacturers, and luminaire specifiers. NEMA LS 20001-2021 is available for download at no cost on the NEMA website.
