Abstract
A light emitting apparatus with current regulated function includes a light emitting diode (LED), and an integrated circuit chip (IC chip). The IC chip regulates current through the LED. Therefore current is constant and does not change with different kind of LED or different level of voltage. When voltage is reversed, the IC chip regulates reverse current to flow through the IC chip and regulates reverse current not to flow through the LED.
