Referring to the drawings, the street lamp 100 according to the first embodiment of the present invention, the strut 110 having a lamp receiving space 112 extending upwardly from the ground and partly long, and from the upper end of the strut 110 Bracket 120 extended inclined downward at a predetermined angle, the side lighting means 130 disposed in the lamp receiving space 112 and illuminates laterally, and is disposed along the side facing downward of the bracket 120. Down illumination means 140 is included.

The strut 110 constituting the main body of the street lamp 100 is, for example, an elongated member extending upward from the base plate 111 fixed to the ground, and has a rectangular pillar shape in this embodiment. The base plate 111 is fixed on a foundation embedded below the ground, for example, commonly referred to as an anchor, whereby the street light 100 is installed at a predetermined position.

A part of the support 110, for example, an upper side of the support 110, is formed with a light receiving space 112. The lamp receiving space 112 may be defined as a space bounded by four connecting members 112a to 112d respectively extending from four corners of the pillar 110 having a rectangular pillar shape. A plurality of side lighting means 130 is disposed in the vertical direction of the support (110).

The lateral illumination means 130 employed in this embodiment is a straight external electrode fluorescent lamp (EEFL), commonly referred to as a "plasma lamp," preferably in the length of the lamp receiving space 112. It has a corresponding length. The external electrode fluorescent lamp is a method in which a fluorescent lamp and a moon electrode are installed outside the lamp, and plasma is induced in the lamp by an electric field applied by the external electrode to emit light, and has low heat generation, low power, and long lifespan. . In the present embodiment, for example, eight external electrode fluorescent lamps are employed, but the number of external electrode fluorescent lamps 130 disposed in the lamp accommodation space 112 may be variously selected according to the specifications of the external electrode fluorescent lamps employed.
