PURPOSE: A substrate holding apparatus of an LED fluorescent lamp is provided to smoothly transfer heat by uniformly maintaining adhesive force between a substrate and a heat cover and to reduce costs by improving an assembling process of a product. CONSTITUTION: A plurality of LED devices(110) is attached to a substrate(100). At least one side of the substrate is supported by a diffusing plate(200). The other side of the substrate is installed in order to maintain constant pressing force with one side of a heat cover(300). The heat cover comprises a curvature portion. The curvature portion adheres closely to one side of the substrate. The heat cover comprises an uneven region. The uneven region magnifies an air contact area. |
