An LED tunnel lamp of the present invention comprises: an LED module part in which a light source, an LED device is installed, and receives power to emit light toward the bottom, which includes a heat dissipation structure and one to four LED modules that can be adjusted in quantity according to required brightness; a housing part in which the LED module part is installed, forms an outer appearance, and has an open back side to easily discharge heat; a converter which acquires a DC output voltage using a switching circuit and supplies power to the LED modules; and a bracket part inside which the converter is installed and which is combined to the housing part to fix the tunnel lamp. The housing part includes: a horizontal frame unit to which the LED module part and the bracket part are combined, and which includes two vertical frames, lengths of which are changed according to the number of installed LED modules; and a vertical frame unit which is inserted between both ends of the horizontal frames and includes two vertical frames forming a specific space by closing one side and opening the other side. The vertical frame includes a header unit forming a specific space with one side closed and the other side opened; and inserted protrusion units protruding from the inside of the top and bottom ends of the header unit to the outside of the header unit, into bar shapes. According to the LED tunnel lamp of the present invention, it is possible to adjust how many LED modules are to be installed to meet the required brightness by changing the lengths of the horizontal frames of the housing part. In addition, it is possible to reduce the number of components required for the tunnel lamp, reduce the manufacturing costs, and improve durability of the LED with a structure good for heat dissipation. |
