Abstract:
1. A light emitting diode (LED) apparatus, comprising: a LED die having a die temperature; and a temperature control and current regulation (TCCR) device electrically coupled in series between the LED die and a power source, and disposed within about 3 cm from the LED die and adapted to sense the die temperature, the TCCR device exhibiting positive temperature coefficient behaviors and having a TCCR resistance adapted to regulate a current from the power source provided to the LED die when the die temperature is in a range of between about 25° C. and about 85° C. and below a trip temperature of the TCCR device, such that: when the die temperature increases, the TCCR device senses the die temperature and thereby increases the TCCR resistance operating in a range of between about 25° C. and about 85° C., thereby decreasing the current flowing through the LED die and decreasing a rate at which the die temperature increases.
