PURPOSE: An LED streetlight is proved to maximally irradiate light and efficiently discharge heat from an LED lamp by closely attaching the LED lamp to an aluminum case. CONSTITUTION: An LED lamp(10) has a heat sink, a reflection shade, an intermediate plate, and a projection unit with a projection window(17). The heat sink discharges heat from the LED lamp. A case(20) is made of aluminum and includes a fixing unit(21) with an insertion unit(21a) and an incline plate(21b), an incline unit(22), a combination rib(23), a combination unit, a folding unit(25), a support rib(26), a protrusion unit(27). A cover(30) has a reflection plate(31) combined with the folding unit of the case, an opening unit combined with a lens(32) and the combination rib of the case, and an insertion unit(35) combined with the incline unit. |
