Monitoring and Quality Control in the Lighting Industry
In the lighting industry, it’s not just about manufacturing light bulbs and LEDs—it’s also about ensuring these products meet the highest standards. Companies involved in testing, validating, and assembling lighting products, such as street lights and solar simulators, play a crucial role.
Given that lighting products emit light, spectroscopy is an essential tool in this industry. It is primarily used for real-time monitoring and quality control throughout the manufacturing process—before, during, and after production.
Avantes offers a wide range of spectrometers and essential accessories like integrating spheres and cosine correctors, specifically designed to meet the rigorous demands of the lighting industry. For precise and reliable measurements, our systems often require intensity calibration. We provide both in-house calibration services and field calibration sources to ensure your systems deliver the most accurate results.
Radiometry and Photometry: Measuring Light with Precision
Lighting is a form of electromagnetic radiation, and radiometry is the science of measuring this radiation. Radiometry involves quantifying electromagnetic waves generated by the oscillation of photons, with the wavelength determining the energy and color of the radiation. Key radiometric parameters include irradiance, radiant flux, and radiant intensity. These measurements are crucial across the ultraviolet, visible, and near-infrared wavelength ranges.
Photometry, on the other hand, focuses on measuring how radiometric sources interact with the human eye. Like radiometry, photometry involves several key parameters, such as luminous flux, intensity, and illuminance.
Avantes instruments support a wide range of radiometric measurements across ultraviolet, visible, and near-infrared wavelengths (250-2500 nm), as well as photometric measurements in the visible spectrum (380-780 nm). The AvaSpec-ULS2048CL-EVO and AvaSpec-VARIUS are our most popular options for these applications, offering precise and reliable performance.
Identifying and Characterizing Lighting Products
Beyond basic radiometric and photometric parameters, additional metrics are used to describe the quality and characteristics of lighting products. These include color, dominant wavelengths, and calculated color temperatures, all of which are crucial for identifying and documenting the specifics of different lighting products.
The lighting industry is rapidly evolving, particularly with the rise of solid-state lighting technologies like Light-Emitting Diodes (LEDs) and Organic LEDs (OLEDs). These advancements are set to replace traditional lighting solutions in the coming decades. To ensure uniform lighting, the LEDs used in any application must match in color. This is where color parameters, determined by a radiometric calibrated fiber-coupled spectrometer such as the AvaSpec-ULS2048CL-EVO, come into play.
An essential aspect of this application is the speed and accuracy with which LEDs are classified. The AvaSpec-ULS2048CL-EVO spectrometers offer high-speed integration and rapid data transfer times, allowing LED sorting machines to operate at maximum efficiency.
