The invention discloses a light-emitting diode (LED) tunnel lamp adopting an extruded radiator structure. The LED tunnel lamp comprises a metal extruded radiator (103) formed by means of an extruding process, wherein an LED lamp bulb (102) is arranged on the extruded radiator (103), and a lamp casing (101) formed by metal punching or plastic die-casting is arranged outside the extruded radiator (103). The extruded radiator (103) is installed on an installing support (106), and an installing interface for installing the LED lamp bulb (102) is arranged on the extruded radiator (103). The LED tunnel lamp is simple in structure, low in manufacture cost, quick, cheap and convenient to install, use and maintain, faults does not easily expand, independent production and use of LED lamp bulbs, lamps and lanterns and illuminating control products are achieved, production links are decreased remarkably, batch production is achieved, and application and industrial scale of LED energy-saving illuminating products are facilitated. In addition, the LED tunnel lamp can effectively solve the problem of illumination glare of a tunnel and enable vehicles to be driven safely.
