Method for determination of efficient lighting use
First Claim
Patent Images
1. A method comprising:
- receiving light from a plurality of light sources using an apparatus configured to analyze and detect a frequency of variation of the light intensity;
determining a type of light bulb and light intensity from the plurality of light sources based upon the detected frequency of variation of the light intensity, the frequency of variation being one of a multiple of a power company supply frequency and 20 to 60 kHz;
determining the geographic area from which the plurality of light sources emanate;
calculating the ratio of light intensities from efficient and inefficient lighting sources for the plurality of light sources within the geographic area and automatically reporting the ratio to one of a carbon offset provider and an enforcement agency; and
reporting the determinations and calculation to a user.
