Light combinated with cable

PURPOSE: A lamp is provided to maximize the longitudinal illumination efficiency of a cable by forming a plurality of lamp mounting grooves in a staircase shaped pattern in a frame. CONSTITUTION: A frame(110) comprises a penetration hole(111), a plurality of lamp mounting grooves(112), a fixing hole(114), and a first clamping bolt(116). A plurality of lamp mounting grooves are formed around the penetration hole. The first clamping bolt is inserted into the fixing hole in order to closely clinch a cable. A lamp(120) is fixed to the lamp mounting groove. A housing surrounds the frame. A bracket rotatably clinches the housing. The bracket is fixed to a top plate. A switch is arranged in the inner structure of the housing in order to control the on/off state of the lamp.
