PURPOSE: A method for manufacturing advertisement signs using light source module is provided to improve workability and reduce a manufacturing cost using a modulated light source which is applicable for various advertisements. CONSTITUTION: A light emitting diode(LED) lamp is connected to other LED lamp in order to secure the stability of a current which flows in the LED lamp. A flexible thin film type printed circuit board(3) is used for connecting LED lamps. Each LED lamp includes a resistance(5) which adjusts a voltage of the current which flows in the LED lamp. The resistance is attached on one side of each lead in the LED lamp. |
