The SmartBeam® Luminance Camera app solves the problem of how to make quick and meaningful assessments of surface light levels. The app turns your iOS device into a professional luminance camera wherever you are. Luminance is a fundamental measure of the brightness of a given surface or the amount of light emitted or reflected off that surface. It also indicates how much luminous power can be perceived by the human eye. The SmartBeam® Luminance Camera app augments the human visual system and increases the dynamic range and ability of the eye to perceive variations in luminance by representing images from the smartphone camera through a calibrated false color filter in real-time. This accentuates the differences in luminance​ in an easy to read manner. The app is intended as a useful, quick and easy to use tool for lighting designers, architects and lighting engineers who are specifying, using, or planning to use, LED lighting fixtures. It is also designed to help the lighting product development process. For instance, the app can be used to quickly measure beam distributions produced by LED lighting products offering considerable time and cost savings over other techniques. A key feature of the app is the ability to share images directly from your smartphone to help collaboration on lighting installations or new lighting product development. Images can also be posted directly to social media. The app also includes the ability to save images for inclusion in reports. For fun, the app can be used to produced luminance photographic maps of your favorite places or people and even fun selfies!
