Modern Lighting Audits – Technology Supporting Designers and Contractors to Verify Lighting Installation Quality
LED products quality assurance has been discussed a lot in the last several years. Many standards and system solutions were developed to control the lighting product quality. Lamp manufacturers and end-users usually focused on better product performance, efficacy and standard compliance. However recently a growing need for dependable and practical on-site LED lighting verification is observed. This is caused both by the new standards for lighting installations as well as newly proposed metrics which help to verify the lighting installations quality. Traditional approach for on-site lighting audits was focused on photometric quantities like illuminance [lx] or luminance [cd/m^2]. Due to the fact that our knowledge about the influence of light onto the human body is increasing and the technology is able to support the effective use of lighting to increase a well-being of people there is a need for tools and complete solutions to verify lighting quality.
This paper will provide a detailed description of a novel solution which is connecting the CAD lighting design software with the on-site measurement supported by new technology illuminance spectroradiometers able to handle measurement procedure to verify and report lighting levels and other quality measures using CAD plans as a reference and reporting illuminance level back to the design software. This especially important for lighting professionals who are dealing with a large lighting designs and installation contracts and they are forced to perform a demanding and time consuming lighting evaluation before the new installation is commissioned. Additional drive for lighting industry added by the Well Building Standard and the Lighting Research Center contribution to our knowledge and practical application of new technology in buildings set new demands for an extended verification of light including color, color rendering and quantifying the photobiological effects on humans in addition to the impact on visual perception. The future of lighting quality control system should provide a practical assistance to lighting industry as the comprehensive lighting evaluation is becoming a necessity for every day application and is no longer limited to a laboratory environment.
