Abstract
In a lamp and method for fabricating the same, an outer surface of the lamp tube is dipped into a conductive transparent solution for forming an electrode by a predetermined depth, and then the lamp tube is pulled out from the solution. Accordingly, an electrode having different profiles is formed on the outer surface of the tube body. Also, the outer surface of the lamp tube is dipped into the solution by an acute angle, and is pulled out from the solution. Therefore, a problem of a nonuniform brightness between lamps is not generated, and light utilization efficiency is much enhanced even when using a plurality of lamp in parallel connected to a power supply.
