PURPOSE:To obtain indicating light having a large amount of light, by collecting and connecting a group of many light emitting diode elements on one heat resisting substrate. CONSTITUTION:On a heat resisting substrate 1, many light emitting diode supporting plates 2 are bonded in the radial direction, with the center of the substrate 1 as a center. One light emitting diode element 3 is attached to each supporting plate 2. A pair of lead wires 4 and 5, which are protruded from the lower surface of each supporting plate 2, are electrically connected by the printed wiring which is provided on the upper or lower surface of the heat resisting substrate 1. Series or parallel wire connections are performed by the printed wiring. Voltage applying lead wires 6 and 7 are connected to the group of the many light emitting diode elements 3 through the lead wires 4 and 5 and protruded from the surface of the substrate 1, then a resistor 8 is connected. Thus a light emitting diode lamp P is constituted. |
