PURPOSE: A luminescent tube for an LED(Light Emitting Diode) and an installing port are provided to be capable of reducing energy waste, improving workability, and obtaining an aiming character or image by installing the LED at the inner portion of the luminescent tube. CONSTITUTION: A plurality of LEDs(100) are connected with each other in series. At this time, the number of the installed LEDs, is up to the magnitude of a supplied voltage. At the time, the LEDs are installed at the inner portion of a luminescent tube(140). Preferably, a positive and negative voltage source(131,132) are connected with predetermined portions between LEDs through the luminescent tube for controlling the LEDs. Preferably, a flexible tube is used as the luminescent tube for forming an aiming character or image. |
