<p>The present invention relates to an LED light of a device focused heat radiation type, which is characterized by comprising a punching hole penetrating from the rear surface of a substrate in which LED is arranged to an LED device center part; and a heat radiation plate forming a heat conduction path conducting heat of the LED device by filling the punching hole with metal and a heat radiation layer radiating the conducted heat not to contact with an adjacent heat radiation layer with metal printing. According to the present invention, provided is an advantage of providing the LED light of a device focused heat radiation type focusing the heat emission of the LED device in a limited area the heat radiation plate has, pumping out, and radiating to the outside.</p> |
