Wallonia LED – Getting its public lighting right

The authorities in Wallonia have decreed: All standard HID lamps will be replaced with LED technology by 2030. ORES, a regional provider of distribution networks that serves over 75% of the municipalities throughout Wallonia, faces the challenge of switching out all 443,164 lights in public spacesby then. In order to ensure the quality of the LED lights before installation, ORES relies on Ophir FluxGage technology for measuring LED luminaires. In just seconds, the compact light measurement device delivers all relevant parameters for comparison against the specifications.

Measurement Technology as a competitive advantage

LED technology has opened up completely new perspectives in recent years: Energy-efficient and compact new lighting scenarios are now a reality for private and public spaces alike. The world leader in LED lighting, Signify – formerly Philips Lighting – has played a major role in this progress.

Signify‘s track record of innovation is impressive, but to ensure that it maintains its edge in the future, the company continuously invests in research and development. Thanks to an innovative measuring system, development

times in the company‘s Hungarian laboratory have been significantly reduced: Signify uses the Ophir FluxGage photometric measurement system from MKS Instruments to quickly and easily measure the main light parameters of an LED luminaire during the development process.

Choosing the optimal FluxGage model for your application

To select the Ophir FluxGage model that will best suit your needs, first consider two questions: What size are the luminaires that you plan to measure (what is their light emitting surface size), and what is their expected luminous flux? The answers to these questions will help you find the right solution. The following table lists the specifications for each of the different FluxGage models:

“FluxGage” A Photometric Test System for LED Luminaires Based on Solar Panels

We present a novel photometric test system for LED luminaires. The new photometric system called „FluxGage“ uses solar panels to detect and measure light. By placing a diffuser and a black pinhole array over a solar panels we achieve a detection surface which is also an absorber. This enables the system to be the same size as the DUT (Device Under Test), as opposed to an integrating sphere which is at least 3 times larger than the DUT. Simulations and experimental results show that this system can measure total flux with an uncertainty of 4.3%. The demonstrated system is used in 2 geometry. The system measures total flux, color parameters (CCT, CRI, chromaticity, etc.) and flicker.

Testing High Volume LED Luminaire Builds

The demand for LED luminaires is growing exponentially. For example, a major Midwest city recently ordered several hundred thousand LED luminaires to replace street lights. Lower operating costs of LED luminaires is driving both commercial and consumer demand. Other attributes of LED luminaires include better and more uniform illumination and the ability to tailor the color of the LED’s to the correct mixture for the individual applications. All of these are major advantages over the use of sodium vapor lamps or traditional incandescent bulbs.
