When using radiation emitting devices for application near mammalian tissue, it is important to control and limit the temperature of the irradiated tissue. In general, heat loss in terms of residual heat from the LED and/or OLED device will be removed to the environment via passive or active cooling. In the case where such a system is undesirable, then the power input to the LEDs and/or OLEDs may instead be limited, such that the heat generated by the LEDs and/or OLEDs does not raise the tissue temperature above acceptable levels.
