CIE 135 Spectrum Testing of Outdoor Sports Lighting
The CIE (International Commission on Illumination) standard 135 defines a method to measure the spectrum and color rendition characteristics of outdoor sports lighting. This service is crucial for ensuring that outdoor lighting meets the stringent requirements set by international standards, thereby enhancing visibility and safety during night-time sporting events.
The primary focus of this testing lies in evaluating how effectively the light source renders colors under various conditions. This is particularly important for outdoor sports lighting where accurate color reproduction can significantly impact player performance and safety. The test aims to ensure that the lights deliver a spectrum that meets both human visual comfort requirements and specific sport-related needs.
The CIE 135 standard specifies a series of tests designed to evaluate the spectral power distribution of outdoor sports lighting. This includes the measurement of luminous flux, color rendering index (CRI), correlated color temperature (CCT), and other parameters that are critical for assessing the quality of light in an outdoor setting. The testing process involves the use of specialized equipment capable of accurately measuring these parameters under controlled conditions.
The specimen preparation for this test is meticulous. The lighting fixture or lamp to be tested must first be installed in a controlled environment where it can emit light under standardized conditions. This ensures that any variations in measurement are due solely to the characteristics of the light source rather than external factors. Once the specimen is prepared, it undergoes rigorous testing using state-of-the-art spectroradiometers and colorimeters.
The apparatus used for this test includes a variety of devices designed to measure various aspects of the emitted spectrum. These include photometric spheres, integrating spheres, and specialized software that can analyze data collected from these instruments. The spectral power distribution is then compared against established norms defined by CIE 135 to determine compliance.
The acceptance criteria for this test are stringent and vary based on the type of lighting fixture being tested. For instance, fixtures used in high-intensity applications such as stadium lighting must meet higher standards regarding color rendering than those used in lower intensity settings like recreational parks. Compliance with these criteria is critical to ensure that the lighting meets both safety and performance requirements.
The testing process involves multiple steps, each designed to gather comprehensive data about the light source's spectral characteristics. These include initial calibration of equipment, setting up the specimen under controlled conditions, collecting spectral data, and finally analyzing this data against established criteria. The results are then reported in a detailed technical document that includes all collected data along with an assessment of compliance.
| Aspect | Description |
|---|---|
| Luminous Flux Measurement | Measurement of the total amount of light emitted by the source. |
| Color Rendering Index (CRI) | Evaluation of how well colors are rendered under the lighting. |
| Correlated Color Temperature (CCT) | Determination of the color appearance of the light source. |
| Spectral Power Distribution | Analysis of the spectrum emitted by the lighting fixture. |
