PURPOSE: A white light emitting diode road lamp comprised of red, green, and blue light emitting diodes is provided to increase a life span and brightness and to reduce energy. CONSTITUTION: A white light emitting diode road lamp comprised of red, green, and blue light emitting diodes includes a road lamp body(1), a heat divergence unit(2), a constant current supply source, and an LED board. The road lamp body is suspended in a specific height of the upper side of the surface. The road lamp body has an opening unit(111) formed in the bottom corresponding to the road. The heat divergence unit is arranged in the road lamp body corresponding to the opening unit. The constant current supply source is arranged in the road lamp body. The constant current supply source provides the current stably. The LED board is arranged to face the opening unit. The LED board is connected to the heat divergence unit. The LED board is connected to the plurality of red, green, and blue LEDs on the side facing the heat divergence unit. |
