Light exposure from at least one light source is received with a light detector of a light monitor that includes at least one of (a) an output device and (b) a communication device transported by a user. The light detector converts the light exposure into an electrical signal, and the current time of day at which the light exposure is received is recorded. An instantaneous light exposure value is generated from the electrical signal, and a weighting function is applied to the instantaneous light exposure value as a function of the recorded time of day associated with the light exposure to produce a weighted instantaneous light exposure value. The weighted instantaneous light exposure value is integrated to produce a weighted cumulative luminous exposure value; and the weighted cumulative luminous exposure value is compared with an established luminous-exposure target.

Monitoring light exposure using a weighting function and light-monitoring system configured for user communication

A light-monitoring apparatus includes a power source, a light detector, a computer processor coupled with the power source and in communication with the light detector and configured to receive and record light exposure detected by the light detector, an output device coupled with the computer processor, and a computer-readable medium coupled with the computer processor and storing instruction code for summing the recorded light exposure from the computer processor over time and communicating a signal to the output device to generate and communicate a signal indicating that a cumulative threshold light exposure for achieving a health benefit has been reached. The apparatus can accordingly be used by an individual to monitor cumulative light exposure from both natural and artificial sources, e.g., in the treatment of seasonal or non-seasonal depression.
