PURPOSE:To enhance the universality of a lead substrate for a light emitting diode lamp by using a common lead substrate for the lamp base of various shapes, and cutting and removing part of the substrate in response to the utility and purpose, thereby enabling to use for the desired lamp base. CONSTITUTION:Each base 10 is punched in a deformed shape capable of arranging elements 2 substantially at uniform positions to a central axis 0. An upside lead piece 11 is connected to the lower side of the base 10, punched in a pectinated shape so that the adjacent lead pieces become parallel to each other, and the adjacent lead pieces are connected by a coupling piece 14a at the lower end of each lead piece 11. The middle lead piece 12 is connected to the lower sides of the same number of the coupling pieces 14a as that of the pieces 11, and punched slightly wider than the piece 11. For example, mounts for respectively mounting resistance elements R1, R2 are formed on the lead pieces 12a, 12b, 12c which are disposed inside, the lead pieces are partly removed suitably in response to the wiring pattern of series or parallel connection of the elements 2, thereby enabling to selectively connect the resistors R1, R2. |
