Abstract
A LED streetlamp is provided. The LED streetlamp includes an integral housing having a light-emitting opening that emits light from a bottom surface and an accommodation space; a power supply unit coupled to the accommodation space through the light-emitting opening of the housing; a reflecting part coupled to the accommodation space through the light-emitting opening of the housing to separate power supply unit from the accommodation space of the lower part and reflecting light from a bottom surface thereof; a substrate for supplying power to multiple LEDs coupled to an inner side surface of the housing of a lower side of the reflecting part; and a cover part. A case with a single structure is provided and includes the power supply unit, the substrate having the LEDs and the reflecting plate to be assembled in the case through the light emitting opening to reduce a manufacturing cost.
