ABSTRACT:
A circle type LED lighting flood lamp using a nano spreader is provided, which can provide a double heat dissipation structure formed by mounting an extended nano spreader having high heat diffusion on the inside of a circular type upper cover and making the extension parts of the nano spreader in contact with a heat dissipation portion in both directions, and prevent a heat dissipation plate from exposing to an outside by fixedly putting the upper cover on the outside of a heat dissipation member to improve the heat dissipation efficiency and the life span of the lamp. The circle type LED lighting flood lamp using a nano spreader includes LEDs, an LED mounting substrate on which the LEDs are mounted, a nano spreader having one side that is in contact with the LED mounting substrate and the other side that is extended for a specified length to form extension parts, an upper cover having inner heat dissipation pins that are in contact with the extension parts of the nano spreader, an upper cap fixed to an upper end of the upper cover, a lower heat dissipation member inserted into the inside of the upper cover and having an inner surface that is in contact with the extension parts of the nano spreader and an outer surface that is in contact with an inner surface of the upper cover, and a lower lens fixed to a lower part of the lower heat dissipation member.
