CONTROL OF LIGHT SOURCES FOR LIGHT THERAPIES
First Claim
1. A light therapy system to activate a light source and apply therapeutic light to a tissue of a patient over a plurality of sessions comprisinga light source and a processor, wherein the processor is programmed to store usage data in a computer readable medium over a plurality of the sessions and to test the usage data to determine if degradation of the light source exceeds a predetermined test value.

Abstract
Light therapy systems that track their own usage and provide for control of light output. LEDs can degrade over time in a way that may not be apparent to a user but impacts therapy. A light therapy system activates a light source and applies therapeutic light to a tissue of a patient during a session. Usage data is stored over a plurality of the sessions and is tested against a predetermined value to determine when further degradation of the light source is unacceptable.

21. A light therapy system to activate a light source and apply therapeutic light to a tissue of a patient over a plurality of sessions, with control of cumulative usage of the light source, the system comprising:
-
a plurality of heads, with each at least one head comprising a plurality of light emitting diodes (LEDs) that provide therapeutic light and are electrically activatable to emit light on the tissue, wherein each head is non-identical and provides a distinct profile of therapeutic light; a body reversibly connectable to each head, with the body being electrically connected to each head to pass electrical power to the LEDs when the head is connected to the body; a computer-readable medium located in each head that stores LED usage data; a computer-readable medium in the body that stores a cumulative, predetermined use test value; and a processor in the body programmed to compare the usage data and the cumulative use test value, the processor allowing LED activation only when the comparison shows that a cumulative use of the head connected to the body exceeds a predetermined test value, with the processor further updating the usage data to reflect LED usage in the session; wherein the body and any of the heads, when connected, form a user-activatable, hand-held, light therapy unit for the user to administer the therapeutic light to the tissue of the user.
