Principle of energy-saving LED

The working principle of energy-saving LED is very simple, the working current of capacitor current limiting the light emitting diode is less than 25MA, plus the C2 absorption of the impulse current lamp switch, effectively led by life's insurance. The capacitor step-down, no electrical energy consumption, no heating, good effect. (current light emitting diode by the capacity of the C1 resolution, such as the maximum figure cannot exceed 474, if the working current of light emitting diode beyond the 50MA, measure the light emitting diode life will be shortened! If you feel that the use of 224 brightness has been too bright, can change the capacity of 104 of the capacitance, so that the working life of LED will exceed tens of thousands of hours.
