PURPOSE:To improve the use efficiency of the light issued by a light emitting element, to make the outward appearance favorable, and to make it easy to see by radiating the light issued by each light emitting element to the outside after reflecting it once at the concave reflecting face. CONSTITUTION:A light emitting element 1a for red color emission and a light emitting element 1b for yellow green color emission are mounted adjacently to one circuit pattern 3 which was formed below a transparent glass substrate 2, and they are electrically connected to the other circuit patterns 4, respectively, by means of wires 5. Also, a reflection member 6 is so attached that the concave reflecting face 7 may cover the light emitting elements 1a and 1b, and each reflecting face 7a-7i constituting the concave reflecting face 7 is so arranged that each reflecting point 9a-9i to each reflecting face 7a-7i of the center point 9 may be positioned on a center axis Xa-Xi. And light transmitting material 8 is charged into the hollow part between the transparent glass substrate 2 and the concave reflecting face 7. |
