Full testing for Photosynthetically Active Radiation outputEvaluation of Yield Photon Flux (YPF). YPF is photon flux weighted by the McCree quantum yield spectrumHigh humidity, high temperature, water spray, and airborne contaminates, like fertilizers, can all effect the performance of horticultural lights. CSA Group can help ensure your horticultural lights will withstand the demanding greenhouse and indoor farming environments seen in todays agriculture. There are a variety of standards which can evaluate the performance of lighting products used in horticultural environments. IEC 600598-1, IP65 or similarANSIUL 1598, Clause 13.4.8, Clause 18.1 can be used to test dialectic voltage breakdown as wellTo understand the eye safety of your fixtures, their photobiological safety should be evaluated and tested to: Evaluation to ANSIIESNA RP-27, Recommended Practice for Photobiological Safety for LampsEvaluation to IEC 62471 (CIE S009)Evaluation to IEC 60825-1Greenhouses often have elevated ambient temperatures and a corrosive environment.

The most popular modern method of producing white light LEDs involves converting blue LED light into longer wavelengths by employing the fluorescent properties of a phosphor compound. LED phosphor is typically imbedded into a silicone, glass, or polymer based substrate to make a lens or encapsulate for the LED (or otherwise placed into the light path). This process converts a blue LED into a white LED. We measure the efficiency of the phosphor lens materials for down-conversion of the shorter-wavelength blue light to longer-wavelength, multi-colored light to determine the overall efficiency of a white LED. Does my product need Bispectral Fluorescence Colorimetry Phosphor Testing? Due to the complicated nature of optical down-conversion using LED phosphor, todays LED industry faces difficulties in measuring LED phosphor lens materials independent of the characteristics of the LED itself. At CSA Seattle, we are proud to be the first to offer a total fluorescence efficiency test specifically geared for the characterization of phosphor lens materials completely independent of an LED. Our phosphor fluorescence testing utilizes a sample of LED phosphor lens material without the LED and characterizes it, providing the user with a completely independent spectral profile which spans the visual frequency range.

CSA Group Seattles Elevated Temperature Irradiance Chamber uses high-irradiance light to accelerate plastic and remote phosphor aging. The results are then measured using photometric test equipment to determine the impact on performance. Robust optics, films, coatings and phosphors are all important components in the design of new SSL products. Accelerated life testing is critical to see how these sub-components, or groupings of them, will weather the extreme conditions created by the day-to-day irradiance of the LEDs and the heat expected within a final product. CSA Group Seattle has created the Elevated Temperature Irradiance Chamber (ETIC) specifically for this type of accelerated life testing. The portable, toolbox-sized test chamber places sub-components (including phosphors) in very high irradiance and temperature conditions to accelerate their aging. The test conditions are achieved with high irradiance blue light focused through the test samples secured inside while using resistive heaters to increase and control the ambient temperature. The materials are subjected to extreme conditions of light and heat to reveal any tendencies for the sub-components to melt, discolor, or fail under the accelerated condition set. All the parameters are software-controlled with real-time monitoring of the test conditions. Proprietary software allows for individual software control for each channel, real-time temperature monitoring, logging, safety, and more.

CSA Group Seattles Electrical Thermal Optical LED Characterization Service (ETO) provides complete Electrical-Thermal-Optical data over your choice of input electrical and thermal conditions. In order to design systems that utilize high power LEDs, the light output characteristics (color and flux) must be known as a function of temperature and electrical input characteristics. Users of this service then can make fundamental design decisions regarding LED selection, thermal management, luminous efficacy, and more. High power LED manufacturers are currently specifying optical output of their LEDs under short single current pulse conditions. Todays high power LED specification sheets generally assume that the junction temperature is equal to the ambient air temperature of 25C. Although these tests are easily repeatable, they are not particularly useful to engineers designing LEDs into illumination and display products. The decrease of luminous flux and shift in wavelength as temperature rises is highly variable and depends on the properties of LEDs. NISTs Optical Technology Division (OTD) is conducting research to address this important issue and recommends LED characterization be performed under TEC Control. This information is necessary when designing robust LED-based products with specific desired light output and lifetime characteristics. LED integrators can now accurately and completely characterize the Electrical Thermal Optical properties of LEDs using CSA Group Seattles services to solve these complex product development challenges.

High Irradiance Stress Testing utilizes CSA Group Seattles Elevated Temperature Irradiance Chamber (ETIC) to evaluate the deterioration of plastic samples and phosphors exposed to blue light irradiance and elevated temperature. Alternate wavelengths can be ordered for custom test conditions. Samples are mounted in the ETIC and stressed to a maximum common irradiance across the chamber of approximately 150, 000 Wm2. Each runtime test can be set at increments of 100 hours with up to eight samples per chamber. When the runtime test is complete, samples are evaluated and a report is generated to the customer. High-Irradiance Stress Testing is useful to manufacturers of SSL lighting components including: Plastic LensingPhosphorsAutomotiveAdhesivesReflectorsCall us at 425-605-8500 or email seattlesales@csagroup.org for price information or an immediate quote today.

About LED Eye Safety Testing Can Light Emitting Diodes (LEDs) used in todays consumer electronics cause eyestrain, headaches, and increased risk of eye damage? Research is increasingly proving these hazards to be of concern, which is why LED Eye Safety Testing is used to determine if there is a blue light hazard. Consumers are regularly exposed to narrow spectrums of intense LED light. This is especially true of white LEDs because they include more blue light emissions, making this is a concern for LED product manufacturers and consumers alike.
