A review on TRIAC controlled energy efficient dimmable LED driver for street lighting

Light emitting diode is most important innovation in the field electronics. The rapid developments in the technologies LEDs are driven for different application. This paper presents the new technology to drive the LED for street light application. The concept is based on digitally controlled TRIAC dimmer which is compatible with LED driver. Dimming is adopted by controlling TRIAC in real time environment without use of additional circuitry Phase angle and LED current is controlled through microcontroller. DC side current regulation is proposed in given system. Small size, high efficiency, no complexity and less development cost are the major features of proposed system. In street lighting, light quality is less important than reliability and efficiency, proposed system provides accurate use of resources reviewing previous technologies with high efficiency and reliability in real time.
