PURPOSE: To attain wide directivity by improving the color mixing at the time of simultaneous lighting of two light emitting diodes varying in light emission colors. CONSTITUTION: This light emitting diode lamp includes leads 12 for mounting chips having a reflection cup 11 at one end, two kinds of the light emitting diode chips 13, 14 which are mounted within the 4 reflection cup 11 and vary in the light emission colors and an approximately bullet-shaped lens 15 which consists of a translucent resin and integrally seals the reflection cup 11 and the light emitting diode chips 13, 14. Two kinds of the light emitting diode chips 13, 14 consist of respectively two pieces of the light emitting diode chips 13, 13, 14, 14 and plural pieces of the light emitting diode chips 13, 13, 14, 14 of the same light emission colors are arranged on the diagonal lines around the central axis of the lens 15 as a center. |
