A streetlight using an LED(Light Emitting Diode) is provided to improve convergence of light irradiated from an LED module by using a prism sheet. A plurality of LED modules include a PCB (Printed Circuit Board). The LEDs are arranged on the PCB. A heat-radiating plate(20) includes a fixing unit and a partitioning section. Adjacent partitioning sections are bent in different directions. Accordingly, an illumination range of the LED module is extended. An accommodating groove(32) is formed in a case(30). The accommodating groove is formed according to a bending angle corresponding to the partitioning section. An extended lens(40) is protruded to the outside of the accommodating groove of the case. The extended lens is used for extending the illumination range of the light irradiated from the LED modules. A fixing member(50) includes a body(52) and a loading unit(54). The extended lens is mounted on the loading unit. A diffuser sheet(60) is arranged between the fixing member and the extended lens. A detaching unit includes a bonding groove, a joint pin, a loading groove, an elastic section, and an open section. A prism sheet(80) is arranged in front of the extended lens. The prism sheet is used for condensing sidelight with front light. |
