Zusammenfassung:	An LED(Light Emitting Diode) street light device is provided to improve brightness of illumination range by scattering a part of LED lights through a scattering member. A case(10) is installed at a leading end of a pillar. A substrate(20) is arranged at inside of the case. A plurality of LEDs(40) are closely attached to the substrate. A radiating part is closely attached to the substrate. The radiating part emits heat due to light emission of the LEDs. A plurality of LEDs have different brightness. A plurality of LEDs are arranged so that brightness gradually increase from the center of the substrate to the edge of the substrate. A scattering member(60) is formed between neighboring LEDs. The scattering member scatters the light of the LED. The substrate is formed in a convex shape. The LEDs are formed at a convex outer surface of the substrate. The scattering member is made of transparent material. The scattering member has a polyhedral shape.
