Lighting - Testing and Certification at the VDE Institute

The market for lighting products is complex. Nothing seems impossible ever since the introduction of LEDs. But what makes quality products stand out and how do you recognize them? What does quality actually mean?

For consumers, quality means that their products are comprehensively safe. In addition, quality products stand out due to a long service life, high durability and electromagnetic compatibility. With our certificates and marks, manufacturers demonstrate to their customers the reliable quality of their products , successfully setting them apart from the competition.

At the same time, it is difficult to penetrate the multitude of standards and guidelines for placing existing and new products on the market in a way that meet market requirements. As an internationally recognized service provider, we guide you through the jungle of regulations and help you bring your product to market in a safe and serviceable manner.

We are your partner for lighting tests

Smart lighting

Smart lighting makes light adapt to the user’s life and needs in an energy-efficient manner. For instance, emotions can be influenced by controlling the light color.

For market players, it means the following: New possibilities, but also new challenges with respect to IT security, interoperability, functionality, serviceability, service life and performance.

Natural light dynamics – human-centric lighting (HCL)

Light has a great effect on your well-being. The human biorhythm follows the lighting situations to which we are exposed during the course of the day. New lighting trends will seize on this effect on the biorhythm.

Light has a great effect on your well-being. The human biorhythm follows the lighting situations to which we are exposed during the course of the day. New lighting trends will seize on this effect on the biorhythm.

This includes the right light color for the appropriate activity: cold white light with greater illumination makes it easier to wake up and work, and warm white light with decreasing illumination makes it easier to relax and prepares you for sleep. There are additional factors with regard to color temperature and the illumination level, such as the angle of incidence into the eye.

The following are requirements for HCL lights

  • Dynamic daytime/nighttime light
  • Good color quality characteristics
  • Color temperature and illumination levels that can change over time.
  • User-oriented lighting

Testing and certifying HCL lights includes product safety according to applicable safety standards and performance characteristics. This includes measuring the light spectra and thus, its effect on biorhythm.

Sustainable lighting

Energy is a scarce good and as such, protecting national resources is our mutual task, which is why sustainability plays an increasingly important role when purchasing electric products.

Energy is a scarce good and as such, protecting national resources is our mutual task, which is why sustainability plays an increasingly important role when purchasing electric products.

We help you demonstrate that sustainability means more for your products and for your company, e.g. via energy labels that underscore your products’ energy efficiency in a promotionally effective manner. Furthermore, we offer you holistic balancing of your products with a focus on the carbon footprint and many other solutions that go beyond the issues of safety and electromagnetic compatibility (EMC).

Optimum - performance of light

Performance became a crucial differentiating factor for quality products, particularly with the introduction of LEDs. During the course of technological change, it was all but difficult for consumers to compare the performance of products.

In our modern lighting laboratory, we have the know-how and the necessary equipment for testing products and highlighting high-performance products. We test the biological effect of light and determine its spectral properties. And we do so flexibly, quickly and around the globe.

Light measurement using the goniophotometer

Photometry and spectrometry – a must for any lighting manufacturer

Photometry and spectrometry are becoming increasingly important for the lighting industry. Transparently evaluating color reproduction and light distribution is usually indispensable for sales.

Photometry and spectrometry are becoming increasingly important for the lighting industry. Transparently evaluating color reproduction and light distribution is usually indispensable for sales.

To meet the demand for independent testing that covers all aspects of the performance characteristics of lamps and lights, the VDE Institute operates a test center for photometry and spectrometry. The scope of services ranges from luminous flux measurement, the color rendering index, spectral value percentages and color temperature to evaluating the photobiological safety, logging the light distribution curve and spatially resolved measurements of spectral distributions.

Everyone can benefit from the VDE’s Properties marks for lighting

Testing according to Zhaga specifications

Standardizing interfaces for LED Light Engines (LLE) is an objective of the Zhaga consortium, an association of companies in the lighting industry. The basic idea is to live up to the quick innovation and development cycles, make the wide variety of different LED modules combinable with each other and thus, continue to drive forward LED technology.

LED light engines consist of at least one LED module, which can be combined with a control gear, if necessary. The goal is to standardize the LED light engines, e.g. the mechanical, thermal, electric, and photometric interfaces, to make them exchangeable. It should be implemented both for newly developed, efficient generations and for different manufacturer products. Zhaga develops specifications, called books, to achieve this standardization, and member companies can voluntarily use these specifications.  However, the goal is to carry over the books into the international IEC standards.

Zhaga has developed a proprietary testing and certification process to test products for their conformity with these specifications. After successful testing, a Logo License Administrator (LLA) issues member companies of the Zhaga consortium a certificate, which grants the right to display the Zhaga logo. It requires the appropriate licensing agreement with the LLA and being a Zhaga member company. Furthermore, the rules stipulate that only authorized test laboratories that have signed a “Testing Center Agreement” may perform the tests. As an authorized test laboratory, the VDE Institute can therefore perform any tests on LED products according to the corresponding Zhaga books.
