The present invention relates to an LED illumination system which receives AC power and radiates light via an LED circuit on which multiple LEDs are arranged. The system comprises: an AC power input unit to which a predetermined voltage of the AC power is supplied; a fuse which shuts off the AC power when an overcurrent flows in the LEDs; a varistor (SVR1) which is connected to the fuse and supplies input power and output power with a predetermined voltage; a bridge diode which is connected to the varistor, performs full wave rectification of the input AC power and supplies one or more paths in parallel with the rectified power; a drive chip which is connected to the bridge diode and drives the LEDs; and an LED module which is connected to the drive chip and is equipped with the LEDs. The present invention has advantageous effects of considerably increasing illuminance by easily connecting the multiple LED modules, conveniently producing the LED illumination system on site because the LED illumination system does not require a conventional converter or an SMPS which has a complex configuration by stably dividing and supplying the AC power, protecting the LED illumination system from the overcurrent or overvoltage for safe use by constantly and stably outputting the AC power when the input AC power is irregular, increasing power efficiency by installing the drive chip which is connected to the bridge diode and drives the LEDs and conveniently connecting and using the LED modules in series by having multiple output terminals which output the AC power to the LEDs. |
