New Zhaga Books Address In-Field Programming Of Smart Lighting

In February, 2022, Zhaga approved Book 25 “NFC Readers with Bluetooth Interface for In-Field Programming”. This new Zhaga specification defines a Bluetooth Low Energy communication protocol for the communication between the field-maintenance application on a smart device and the Near Field Communication (NFC) reader.

In February, 2022, Zhaga approved Book 25 “NFC Readers with Bluetooth Interface for In-Field Programming”. This new Zhaga specification defines a Bluetooth Low Energy communication protocol for the communication between the field-maintenance application on a smart device and the Near Field Communication (NFC) reader. Together with Book 24, which describes the programming of luminaire components using NFC, these specifications solve the data management problems of smart luminaires with interoperable maintenance tools, enabling configurable luminaires that are easy to service over their entire lifecycle.

An increasing number of lighting applications require reading out parameters and changing settings of LED drivers in the field. Manufacturers of LED luminaires currently use a variety of methods for in-field programming. The new Zhaga NFC Books give installers, system integrators and utility companies the option to select just one programming tool which works with all field-maintenance applications from all vendors implementing Book 25, and all NFC-programmable devices implementing Book 24.

Zhaga Book 25 builds on Book 24 “Programming of Luminaire Components Using NFC”, and adds mobile NFC Readers with a Bluetooth Low Energy interface. It enables maintenance and replaceability with a cross-vendor harmonized method of NFC programming for in-field use.

The specification defines a Bluetooth Low Energy GATT-Service which NFC Reader manufacturers can implement for the communication between the field-maintenance application on a smart device (cell phone, tablet, etc.) and the NFC reader. This allows the field-maintenance application to read and write parameters on NFC enabled LED drivers without the need for a cable-based connection. Field maintenance with Book 25 may also be used for other components requiring programming, such as sensors or connectivity nodes.

Zhaga has also developed the Zhaga-NFC certification program for Book
24 and Book 25 which is available for Regular and Associate Zhaga
members and is provided by Zhaga accredited test centers listed on the
Zhaga website. Only certified NFC readers and NFC-programmable devices can carry the Zhaga-NFC logo. This certification builds trust in the interoperability of components. More information is available here.

Could Sustainable Lighting Product Regulations Be Coming to North America?

Industry discussions about sustainable lighting are increasing, but what would sustainable product regulations look like? The European Union (EU) is far ahead of North America on sustainable product regulations, and a look at what the EU is doing gives one vision of where sustainable product regulations could go in North America.

Industry discussions about sustainable lighting are increasing for a variety of reasons:

  • NAILD’s recent open letter calling for more sustainable LED lighting products. Details here.
  • Vermont’s first-in-the-nation ban on all 4’ linear fluorescent lamps, based on mercury, not energy efficiency. Details here.

But what would sustainable product regulations look like? The European Union (EU) is far ahead of North America on sustainable product regulations, and a look at what the EU is doing gives one vision of where sustainable product regulations could go in North America. Here is a synopsis of the EU approach, from the National Law Review, in April:

At the end of March, the European Commission (Commission) presented the Sustainable Products Initiative (SPI) as part of a ‘Circular Economy Package I’, and proposals for a new directive empowering consumers for the green transition, and a new Construction Products Regulation.

The Commission aims at “making sustainable products the norm” and reducing negative life cycle environmental impacts of products, while benefitting from efficient digital solutions, by setting a framework for Ecodesign requirements, creating an EU digital product passport and tackling the destruction of unsold consumer products.

In particular, the SPI includes the proposal for an Ecodesign for Sustainable Products Regulation (ESPR), which would repeal the current Ecodesign Directive 2009/125. It establishes a horizontal framework and broadens the scope of the Ecodesign Directive beyond energy-related products, i.e. beyond any product that has an impact on energy consumption during use. The new Regulation would apply to all physical goods, including components and intermediate products, except food, feed, medicinal and veterinary products, living plants and animals, and products of human origin. According to the Commission’s explanatory memorandum, the ESPR is meant to address products that are not covered by existing legislation or where that legislation does not sufficiently address sustainability, and Ecodesign requirements in the delegated acts that it will adopt cannot supersede requirements set in legislative acts (of the Council and European Parliament).

The proposed regulation provides a framework for the Commission to adopt delegated acts with specific requirements for a product or group of products, following the approach of the current Ecodesign Directive. It would task the Commission with adopting a Working Plan with a list of products for which it plans to adopt such delegated acts, covering at least three years, thus providing some predictability. The Commission would have to prioritise products based on their potential contribution to the EU climate, environmental and energy objectives, and for improving the product aspects without disproportionate costs to the public and economic operators. The Commission stated that it has preliminarily identified textiles, furniture, mattresses, tires, detergents, paints, lubricants and intermediate products like iron, steel or aluminium as suitable candidates for the first ESPR Working Plan. It expects to prepare and adopt up to 18 new delegated acts between 2024 and 2027 and 12 new delegated acts between 2028 and 2030. In its proposal, the Commission foresees budget implications, as it would need significantly more staff to implement the Ecodesign framework. It estimates that it will have to increase its dedicated staff from currently 14 to 44 in 2023 and up to 54 in 2027.

For anyone who thinks that EU sustainable product regulations could never cross the Atlantic, remember that California modeled its 2017 RoHS regulations on EU RoHS regulations. It’s certainly plausible that legislatures in California, Vermont, Canada, and other progressive state governments could introduce aspects of the new EU scheme.

THE CHIPS AND SCIENCE ACT OF 2022

Last week, the U.S. House and Senate each passed the CHIPS and Science Act, which provides $52 Billion to boost domestic production of computer chips, but also contains worker training funds and prevailing wage requirements for employers in the semiconductor industry. At the time of writing this article (7/31), the bill was on President Joe Biden’s desk, awaiting his expected signature. The law will direct $40 Billion to increase manufacturing, and $12 Billion for R&D. Today, only 12% of high-end semiconductor manufacturing is done in the U.S. The CHIPS and Science Act is expected to significantly increase that percentage.

INTEL PLANT

In January of this year, Intel announced plans for a new $20 Billion computer chip manufacrturing hub near Columbus, OH. The company expects it to grow to become one of the largest semiconductor manufacturing sites in the world. Back in June, Intel’s CEO warned that the new plant was in jeopardy if the Congress didn’t pass the CHIPS and Science Act. That issue is resolved with the Senate and House passage of the bill, last week.

SAMSUNG PLANT

In November 2021, Samsung announced its plan to build a $17 Billion computer chip factory, outside Austin, TX. To reinforce the deal, President Biden visited a Samsung plant in South Korea, during his recent visit, in May, 2022.

The three actions above represent $89 Billion of new investment in the US semiconductor production industry. This will boost the US economy and reduce computer chip costs, impacting countless industries, including automotive, computers, consumer electronics, IoT, and lighting.

Four New ANSI/IES Standards Released

The Illuminating Engineering Society (IES) recently introduced four new standards documents addressing current challenges that face the lighting industry – navigating near-field photometry, standardizing iterations of lighting controls intent, the importance of UV lighting, and promoting a balanced outdoor environment.

The Illuminating Engineering Society (IES) recently introduced four new standards documents addressing current challenges that face the lighting industry – navigating near-field photometry, standardizing iterations of lighting controls intent, the importance of UV lighting, and promoting a balanced outdoor environment. The four new standards are available in the IES webstore, and include:

  1. Recommended Practice: Lighting Exterior Applications (ANSI/IES RP-43-22)

This document provides pedestrian-oriented illumination recommendations for the reassurance, safety, comfort, amenity, and enjoyment of people in outdoor environments. This RP takes a comprehensive approach and makes recommendations based on lighting zone, glare avoidance, spectrum, and other visually influential conditions. Application of these recommendations will ultimately enhance the visual experience for people while also respecting the environment. Available here.

  1. Lighting Practice: Documenting Control Intent Narratives and Sequences of Operation (ANSI/IES LP-16-22)

 Intended for a variety of users in the lighting community, this document provides guidance on the documentation of Control Intent Narratives and Sequences of Operation. It is not intended to be a design guide but rather a reference manual of best practices on how the design, once formulated, is included in the project documentation and communicated to the construction and commissioning teams. Available here.

  1. Approved Method: Application Distance Radiometry (ANSI/IES LM-91-22)

In near-field conditions, the use of far-field IES-format photometric files results in substantially incorrect irradiance, illuminance, or photon-flux density values being predicted by lighting layout models constructed for near-field conditions. This problem can be overcome by using distance-specific IES file(s), generated by first collecting data at the working distance(s) of interest, obtained from a single luminaire and then converting them to distance-specific IES file(s), following the protocol described in this document. Available here.

  1. Approved Method: Optical and Electrical Measurement of Ultraviolet LEDs (ANSI/IES/IUVA LM-92-22)

This document is a guide developed for the measurement of ultraviolet (UV) light emitting diodes (LEDs) and describes the procedures to be followed and precautions to be observed in performing measurements of total radiant flux (total radiant power), electrical power, and wavelength characteristics of ultraviolet (UV) light emitting diodes (LEDs). Available here.

Emergency Lighting That Preserves Architectural & Interior Design Integrity

Discovered at LightFair 2022 – Concealite -The company specializes in emergency lighting and other building life safety equipment designed to disappear into the wall until there is an emergency.

One of my more interesting finds at LightFair was Concealite’s booth. An example is their 5000 Series Emergency Lighting, which includes a self-contained battery system (see image).

Typical emergency lighting fixtures are obtrusive and interrupt the aesthetic beauty of interior designs. Concealite offers an elegant alternative to “bug eyes”. Only when the system is activated, do the high-powered lamps become visible, rotating 180 degrees to begin operation. The result is a clean, almost invisible installation that does not conflict with building interiors. Additional features include:

  • Units can be customized in the field using paint, wallpaper, or applique finishes.
  • Designed for wall or ceiling installations, including gypsum board, plaster, or acoustical tile.
  • Choice of standard 90 minute, 2 hour or 4 hour operation.
  • Self-diagnostic controls are an available option.
  • Vandal-resistant
  • Listed to UL Standard #924 when installed in accordance to Article 700 of the National Electrical Code.

The company has applied the same approach to motion detectors, offering a discreet and vandal-resistant alternative to visible surface mount detectors. Only when the commercial or residential security system is activated does the detector become visible, rotating 180 degrees to begin operation (image above).

Similarly, the company offers concealed UV disinfecting lighting, fire alarms, and exit signs. To learn more, visit their website here.

Cree LED Was Colorful At LightFair

David enjoyed a product demo from Cree LED at LightFair. Their booth emphasized their latest color LEDs, as well as their RGBW packages.

At LightFair, I enjoyed a product demo from Cree LED. Their booth emphasized their latest color LEDs, as well as their RGBW packages. The big splash was their recently released XLamp® Element G (XE-G) LEDs. The XE-G line includes 9 direct emission colors and 8 phosphor-converted (PC) colors. With 17 colors and a full portfolio of white options (6500K-2700K; 70-90 CRI), the new XLamp XE-G LED family delivers industry-leading output/efficiency, in a small form factor.

Equally interesting were the RGBW LEDs, the XLamp XM-L Color Gen 2 LEDs. They enable high output, up to 1,400 lumens, and color mixing for directional RGBW luminaires. The XM-Ls do all of this in a tiny 5.0 x 5.0 mm package. The XLamp XM-L Color Gen 2 LEDs feature the smallest possible distance between LED die, creating a small optical source for excellent optical control and efficient color mixing. Gen 2 also includes a new High-Intensity version that further reduces the optical source size for even greater levels of optical control.
