In this paper, simple LED driver is proposed. The proposed driver has simple construction having series capacitor, bridge rectifier, and adjustable regulator IC. Constant current control is possible with the use of TL431Z. The proposed in this paper, current is greater than the rating of the load, the current controller device measures the increased current in the circuit, and turned-on so that the current will be shared. Thus current control device makes the circuit more reliable, longevity as well as increase the luminous efficacy of the LED light. The simulation and experimental results are presented to show the validity of the proposed circuits.
