The invention discloses a LED (light emitting diode) tunnel lamp with adoption of a double-sided radiator and a lamp housing support structure, comprising a lamp housing (101) molded by metal punching or plastic die-casting process. The lamp housing (101) comprises a mounting interface supporting plate and a foot screw hole, the mounting interface supporting plate is used for mounting the double-sided radiator (103), and the foot screw hole is used for fixing and mounting the whole LED tunnel lamp; more than one rectangular opening used for mounting the double-sided radiator (103) is arranged on the mounting interface supporting plate, a mounting interface is arranged on the double-sided radiator (103), and an LED bulb (102) with water-proof and dust-proof functions is arranged on the mounting interface. The LED tunnel lamp is simple in structure, low in manufacturing cost, is rapid, cheap and convenient to install, use and maintain and is not easy to expand fault; bulbs, lamps and lighting control products of LED lamps are independent in manufacturing and using, production links are greatly reduced, mass production is realized, and the application and industrial scale of the LED energy-saving lighting products are facilitated.
