PURPOSE:To increase the amount of light in the forward direction per one light-emitting diode by using devices, top sections of which are molded so as to be formed to a convex lens by a light-transmitting organic high molecule, as the light-emitting diodes and mounting parabolic reflecting mirrors to each light-emitting diode. CONSTITUTION:A device molded so that a top section thereof is shaped to a convex lens by a light-transmitting organic high molecule is employed as a light-emitting diode 2. Consequently, beams emitted in the vertical direction or the direction close to the direction from the light emitting diode 2 are converged by the convex lens, and emitted forward. On the other hand, beams emitted in the direction oblique to the horizontal direction or the vertical direction from the light-emitting diode 2 generally intend to be changed into scattered beams, but each light-emitting diode 2 has parabolic reflecting mirrors 3, and beams emitted in the direction are reflected and converged in the forward direction by the reflecting mirrors 3. Accordingly, the amount of light in the forward direction is increased remarkably. |
