Article: Zhaga meets Smart Lighting

LED Professional Mar/Apr 2016

At first glance, the standardization of LED lighting components seems to be quite remote from the rise of smart, connected lighting and the Internet of Things (IoT). But the projected growth in penetration of smart lighting can only be realized through developments in high-volume electronics and standardization. Such standardization is intended to remove arbitrary variations in components, making design and implementation easier for manufacturers of smart LED luminaires, and enabling a supplier ecosystem. This is where Zhaga comes in. Read the full article

Interview: Kraig Kasler, Cooper Lighting

LightNow blog, December 2014

This detailed interview includes a section on serviceable components: "The requirement and demand for serviceable components is directly correlated to the overall cost of the LED luminaire. Of course, as the reliability of both the LED devices and LED drivers continue to improve, the need to service the LED-based products is diminished as well. A related aspect to the design of LED luminaires is the opportunity to “swap out” components in order to meet specific customer needs (i.e. color temperature, optical distributions, aesthetics, etc.). This approach is being addressed by industry groups like Zhaga, based on global, consensus standards efforts."

Event Review: Busting Myths on Zhaga

LED Inside, March 2014
Members of the Zhaga Consortium clarified some of the misconceptions about Zhaga during the recent seminar at the Taiwan International Lighting Show (TILS).

Event Review: Seven Challenges Lighting Designers Face when Using LEDs

LED Inside, March 2014
James Wallace, Principal and Design Director of Light Plan and Director of the Professional Lighting Designers’ Association (PLDA), spoke at the recent TILS show in Taiwan. Interchangeability was one of the challenges that he highlighted:

"#6 - Interchangeability: Clients expect long lifetimes for LED lights that tend to last at least 30 years, making component interchangeability increasingly important. Although, Zhaga has taken steps in introducing interchangeable lights into the industry, it is not enough, said Wallace. The Australian designer noted Zhaga specifications are designed from manufacturer perspective, but not from the end-user’s perspective of interchangeability."

LEDs Magazine, March 2014
The Zhaga Consortium will be under new leadership effective April 1, 2014 when Musa Unmehopa takes the position of Secretary General, replacing Menno Treffers who has guided the organization since its inception. Zhaga has also announced that going forward it will develop specifications for the electrical interface between drivers and LED modules that together form an LED light engine (LLE) allowing independent interchange of either the LED module or driver.

Menno Treffers, General Secretary of the Zhaga Consortium, discusses the Zhaga Consortium’s latest activities. He explains what successful luminaire manufacturers take into account for their LED lighting strategies with the help of the Zhaga specifications. The lowest Bill-of-Material costs for a single luminaire are not low enough to make a profitable portfolio in LED lighting. R&D costs, stock level costs and risk factors have to be taken into account as well. (Vist the magazine website - subscription required.)
