<P>PROBLEM TO BE SOLVED: To solve a fault in a small daytime-beacon effect due to a small projection area, a difficulty to be set up without using a heavy machine due to a heavy pole itself and a fault to decrease a visibility at night when a light overlaps a background light. <P>SOLUTION: A beacon light is provided with a beacon body 1 to assemble three sheets of trapezoid-shaped side plates 1a so as to obtain a triangular pyramid trapezoid shape. The light 3 is provided at a top of the beacon body 1. A lod light-emitting type provided with a light emitting lod 7a is adopted and a light-emitting body is provided with an auxiliary light 7 of a LED 7b. As the beacon body 1 has a triple-plane shape, the daytime-beacon effect is big. As three sheets of the side plates 1a is light-weighted compared with one conventional pole, an assembly without using the heavy machine is possible. When the auxiliary light 7 of the lod light-emitting type is provided, the visibility at a short distance is improved as the light is emitted for a long term at both right and left sides of the triangular pyramid trapezoid shape. As the auxiliary light 7 is provided besides the light 3, the visibility at night is not influenced even when the light 3 overlaps the background light. Because the light emitting body is the LED 7b, its power consumption is low, its working cost is inexpensive and it is used for a long term. Each side plate of 1a and 1a may be split into up and down parts. <P>COPYRIGHT: (C)2008,JPO&INPIT |
