The invention discloses a fence type LED lighting lamp, comprising radiator units, a baffle plate, a power supply shell body and a high-power LED, the radiator units are arranged to form a fence-shaped structure according to the parallel connection mode, and the radiator units are mutually completely isolated by air; the baffle plate, the radiator units and the power supply shell body are fixed by the penetration and connection mode by using bolts and seal heat conductive bases in the radiator units; an LED driving plate is fixed in the power supply shell body, and a cover plate is fixed on the power supply shell body. The radiator units solve the embodiments of various radiation structures, the light-emitting angle can be adjusted, the light shape thereof can meet the light-matching curves of the lamps which are needed by the different places, when in different light irradiation directions, a radiation channel of the lamp is smooth, thereby being capable of preventing the accumulation of dust and maintaining the initial radiation effect. Each radiator unit is composed of the heat conductive base, a heat conductive plate, a heat transfer plate, a radiating plate and a vertical column type radiator, the radiator units are produced by using aluminum material with good heat conductivity through extrusion process, the radiator units can be cut for use, and the structure is compact, thereby being capable of meeting the high-power or other semiconductor lighting lamps, such as development street lamps, tunnel lamps, projection lamps, automotive headlights, etc.
