An LED lighting flood lamp (100) having a double heat dissipation plate structure using nano spreaders (130) are provided, in which the double heat dissipation plate structure is formed by installing the nano spreaders (130) having high heat diffusion inside the lamp and forming heat dissipation plates on upper and lower parts of the nano spreaders, and heat dissipation pins are arranged in zigzag on the upper part of the upper heat dissipation plate, so that the heat dissipation efficiency is maximized, and the lamp has a slim external appearance without being limited in installation space. The LED lighting flood lamp includes LEDs, an LED mounting substrate (120) on which the LEDs are mounted, nano spreaders (130) mounted on an upper side of the LED mounting substrate (120), an upper heat dissipation plate (150) fixed to an upper side of the nano spreaders (130) and having a plurality of heat dissipation pins formed on an upper surface thereof, a lower heat dissipation plate (160) fixed to a lower part of the LED mounting substrate, and a diffusion lens plate (180) fixed to a lower part of the lower heat dissipation plate (160). |
