Ten machine sizes - multiple goniophotometer configurations

robogonio combines the flexibility of a KUKA industrial robot with the precision of the opsira light measurement technique. Depending on the request, different detectors can be combined with robogonios of various sizes.

The crucial configuration attributes are

  • size and payload of the robogonio
  • detector equipment

This opens up countless possibilities for the configuration of your own robogonio. The choice of goniophotometer is facilitated by the three product lines with clearly defined detector equipment.

Many goniophotometer types - one device

With its six axes, the robogonio combines multiple goniophotometer types into one device, defined in the following standards:

  • DIN 5032-1
  • DIN EN 13032-1
  • CIE 121
  • CIE S 025

Especially type 1.1, 1.2 and 1.3 are a piece of cake for the robogonio. In these types, the detector stays stationary while the sample (light source, luminaire, display, LED …) rotates around its axes, entirely conform to the latest standardization DIN EN 13032-4, CIE S 025.

robogonio BSDF

Module for fast spectrally resolved scatter light measurement

Current developments in photonics use new materials to combine light conversion and light scattering. High power density, small dimensions and the mutual influence of conversion and scattering make a simulation of light conversion and light scattering impossible. Spectrally resolved scattered light measurements are a crucial prerequisite for the development of even more efficient light sources.

The standard measurement method for determining the BSDF (bidirectional scattering distribution function) / BRDF (bidirectional reflectance distribution function) is goniophotometry. The sample is mounted on a specimen fixture. Lighting and a detector are positioned relatively around the sample. Scattered light goniophotometers have a complex and expensive setup and are slow. In the project, a new, fast and cost-effective solution for scattered light measurement was developed. Thus, a new module is added to the proven opsira robotic goniophotometer (robogonio) to enable fast and cost-effective spectrally resolved scattered light measurements.

The robogonio is a very versatile system to realize the relative solid angles and distances between the DUT (luminaire, lamp) and the detector system required for photometric measurements in a very wide range.

The aim of the project was to develop an additional module for the robogonio, which realizes the need of at least 2 more axes without an additional device, but as an additional "claw" attached to the robogonio.  

The new robogonio BSDF will be presented during the next Light+Building Tade Show from October 2nd to 6th, 2022 in Frankfurt/Main in Germany, opsira Stand F70 – Hall 8.0.

This Project is supported by the Federal Ministry for Economic Affairs and Climate Action (BMWK) on the basis of a decision by the German Bundestag.

Applications

Automotive

In the automotive industry, two aspects of photometric measurement are of particular importance: Results need to be delivered extremely quick and authoritative and the measurements have to be executed with the finest angular resolutions so that the tests comply with the applicable standards.
The robogonio meets both of these criteria perfectly. The speedy high-end-photometer reduces the time required for classic goniometric measurements to a few minutes. Moreover, the robogonio permits angular resolutions of 0.01°, thus enabling precise observance of the cut-off line.

Luminaires

Constantly launching new variants of luminaires, easily providing light planners with far field data (IES or EULUMDAT), and quickly generating the requiredc LED data. The robogonio stands for a measuring solution that fulfills all these requirements with ease.
The optional spectrometer also enables color-over-angle measurements. Optic designers can now determine how the color changes at certain angles and whether unwanted color effects occur.
Another important aspect is the measurement of the total luminous flux in relation to the consumed electrical power. Luminous flux efficiency in lumen/watt as well as energy efficiency classes can be determined directly.

Signal lights

Luminous intensity distribution is an essential factor for measuring traffic lights, railway signals, beacons or signal towers for production lines. Some applications present the additional challenge of the front and back light exit windows having to emit the exact required quantity of light.
Here, the robogonio impresses with its flexibility since it can measure the luminous intensity distribution in both directions using arbitrary cebtres of rotation in space.
Standard-relevant testing areas are covered automatically by the robogonio.
For fast and efficient work, the robogonio enables integrating user-defined measuring processes.

User Report - Goniophotometry with LED Linear

 

The LED market is fast-moving, and the trend goes to increasingly small luminaires with continuously improved optics. The light lab of LED Linear, the specialist for linear illumination systems, has been accredited by the DAkkS in acc. with DIN ISO/IEC 17025 since the middle of 2018 and is designed for precisely these challenges.

Dino Iavarone, head of measuring technology, explains how LED Linear does it: "We use the most modern measuring technology. Also, the robogonio goniophotometer allows us to perform measurements very fast and precisely. Speed is worth real money nowadays." In addition, the color spectrum and temperature can even be measured in the outmost angle of radiation. "Making these values quantifiable is becoming increasingly important in optics development." The product development at LED Linear
profits from all these advantages just as much as smaller manufacturers without an accredited lab, because all services are also available to external customers.

Planning stress tests for luminaires and optics: anything can be measured.
