The invention is a method and apparatus to provide a temperature compensation for LED brightness utilizing temperature dependence of voltage-current characteristic of the LED. Methods ensure the precise compensation of brightness of LED using two or more temperatures to tune an LED driver circuit without the use of thermistors or other temperature sensor.This method also allows for circuits that compensate brightness not only of a single LED but of an assembly of LEDs. The method allows to manufacture LED modules with built-in temperature brightness compensation circuit. These modules can be used in a variety of illuminating equipment including but not limited to home lights, vehicle turn or brake signals, traffic lights, and a backlight for LCD display.
