A LIGHT METER FOR DETECTING AND MEASURING INTENSITY OF TWO OR MORE WAVELENGTHS OF LIGHT

摘要

A light meter (200) for detecting two or more different wavelengths of light and methods for determining whether a light source configured to emit light at two or more dominant wavelengths is working properly. The inventive light meter (200) includes a housing (201), two or more receiving means (202, 204), for example, LEDs for receiving light energy emitted by an external light source wherein each receiving LED (202, 204) is configured to receive light energy of a desired wavelength, and display means, for example LED bar displays (206) for providing a visual indication of the existence and intensity of one or more wavelengths of light energy received by the receiving means.
