PURPOSE:To produce an emitted light indicator with high reflecting power by a method wherein a part of lead frame end is made into a reflecting part reflecting the light reflected from LEDs efficiently. CONSTITUTION:A lead frame 11 made of highly glossy Ag-Ni alloy etc. is provided on a point symmetrical with respect to the central point A. The lead frame 11 respectively bent at the ends and the central part is composed of mount parts mounting LEDs 12 alternately at the ends and reflecting parts 14 inclined upward at an obtuse angle with respect to the mount parts 13. Besides, the peripheral part of the ends of the frame 11 is made into plated parts 15 made of Ag etc. centered on a point A excluding the reflecting parts 14 to be connected with one another. Through these procedures, an emitted light indicator with high reflecting power may be produced at lower cost due to the only one component of the leadframe 11. |
