LED TUNNEL BOUNDARY LINEAR GUIDE LAMP FOR IMPROVING VISIBILITY AND VISUAL ADAPTATION OF A DRIVER INSIDE A TUNNEL

摘要

PURPOSE: An LED tunnel boundary linear guide lamp is provided to improve visibility and visual adaptation of a driver inside a tunnel by improving an existing road boundary linear guide lamp.;CONSTITUTION: An uneven endoergic frame(12) is formed on the front side of a body(11) in a longitudinal direction. An LED bar installation unit(13) which has a groove shape with a level difference is formed on the central part of the endoergic frame. A cap fixing unit(14) is formed on the upper and lower parts of the front side of the body. A slit type heat dissipation frame(15) is arranged on the rear surface of the body in the longitudinal direction. An LED bar(20) is controlled by a drive control circuit. A light diffusion cap(30) is fixed to the cap fixing unit in order to cover the front surface of a casing by the upper and lower parts. A side cover(40) covers front and rear side surfaces of the light diffusion cap. A bracket(50) attaches the casing on the upper part of a tunnel curb.;COPYRIGHT KIPO 2012
