<p>A traffic signal indication using an LED is provided to apply LEDs and an LED beam light guide bar to the signal indication, thereby remarkably extending a usage time of a battery while increasing a life of the signal indication and elegantly showing a luminous display state of the signal indication. A light guide bar(16) is manufactured in square bar or circular bar shape by being made of a transparent resin material. A translucent layer(24) is formed on a circumferential surface in length direction of the light guide bar(16) to disperse a beam moving along an internal light guide path of the light guide bar(16) in all directions. An LED holder(15) is combined with one-sided section in length direction of the light guide bar(16), and has a connection terminal for a PCB(22). One or more than two LEDs(18) radiate(s) the beam inside the light guide bar(16) by being mounted within the LED holder(15).</p> |
