A combined type three-dimensional heat radiation structure fully utilizing heat radiation space for LED lamp is formed by combining an external heat radiator (1) and an internal heat radiator (2), wherein the bottom of the internal heat radiator (2) is connected with an LED display panel (4); the top of the external heat radiator (1) is connected with a lamp joint and a power supply box (5); a combined type discontinuous multilayered three-dimensional heat radiation structure is arranged on the top of the internal heat radiator (2) and consists of a plurality of heat radiating fins; and a cavity is formed between the adjacent heat radiating fins. The heat radiation structure increases the total area of heat radiation, maximizes the effective heat radiation area, and improves the heat radiation effect. |
