<p>The present invention relates to a street lamp having light emitting diode (LED) unit modules capable of improving the intensity of illumination around the side and central area on the surface by having multiple LED unit modules radiating lights to a certain direction and extending the lifetime of street lamp by having a double radiating structure on the LED unit modules. The street lamp having LED unit modules includes: a body housing containing multiple LED unit modules by being combined to the end of a pole standing on a road by a supporting rod inserted into the end of the pole; and multiple LED unit modules spreading LED lights on the ground, stored in the body housing. The LED unit modules include: a central LED unit module spreading lights toward the bottom of the surface; a third LED unit module spreading lights toward the right side of the surface, arranged next to the central unit module; and a fourth LED unit module spreading lights toward the left side of the surface, arranged to the other side of the central unit module. In this way, the present invention spreads LED lights evenly on the ground. At the upper part of the main frame of the LED unit module, a plurality of radiation pins for emitting heat generated from the LED substrate to the other side is formed. At the outer surface of the two sides of the sub-frame mounted on the upper side of the main frame to be slid, a plurality of radiation pines emitting heat generated from the power supply device to the outside is formed.</p> |
