Abstract:
1. An illuminating apparatus comprising one or more LED-type illuminating modules, each of the one or more LED-type illuminating modules comprising: a radiator radiating heat generated from LEDs and formed of a light metal alloy, the radiator including a light transmission and diffusion plate mounted in a bottom of the radiator by ultrasonic fusion-bonding and transmitting and diffusing light emitted from the LEDs; an LED substrate including the LEDs and mounted in the bottom of the radiator by screws; a waterproof ring sealing a gap between the light transmission and diffusion plate and the radiator; radiating plates formed of the light metal alloy in a radial pattern for radiating the heat generated from the LEDs and having holes and recesses for receiving the conical radiating rods, the conical radiating rods supporting the radiating plates such that the radiating plates are in spaced apart steps by the supports of the conical radiating rods and in parallel with the body of the radiator; a housing including a cover on a top of the housing, pushrods in a bottom of the housing, a pair of screw couplers on a first pair of outer walls of the housing and a pair of screw passing holes in the bottom of the housing, the housing being formed by injection-molding a conductive polymer resin material in a square shape and detachably coupled with the cylindrical radiating rods and the radiating plates to radiate heat transferred from the radiator and the radiating plates; a waterproof packing provided between the housing and the cover to seal the housing; and a power supply converter provided in the housing and supplying power necessary to drive the LEDs mounted on the LED substrate.
