PROBLEM TO BE SOLVED: To obtain light color needed to a head light to beautifully constitute the head light at the time of luminescence by the arrangement of the light color, by appropriately combining the kinds and the number of luminous elements forming three original colors. SOLUTION: In constitution where respective luminous elements 39 are joined to be adopted as a group, the luminous elements 30 are soldered to an electronic board 34 in the portions of lead wires 31, and are fixed to a case 35 together with the board 34, except the portions of convex lenses 32, to be adopted as a group. In the luminous elements 30 thus constituted, the portions of the convex lenses 32 are exposed from the case 35, a supporting frame, to direct these respective optical axes to one point. By making the focal distances and focal depth of the respective convex lenses 32 almost constant, light emitted from the lenses 32 are projected in a circle, having the same core and size, onto a light receiving plate, and several kinds of light are overlapped to make the light have daylight color or white. The luminous elements 30 adopted as a head light 20 are connected in series at every color of red, blue, and green adopted as three original colors, and these connected elements 30 are connected in parallel to a power source. |
