オード４から出た光は前面レンズ１を透過し該レンズを
照明する際拡散レンズ２によって拡散される。The use of light bulbs instead of light bulbs as a light source for taillights and the like has become increasingly popular, and the one shown in FIG. 8 is known as an example. Namely, numeral 1 is a front lens having a densely formed diffusion lens 2 consisting of a large number of small convex lenses on its inner surface, and numeral 3 is a front lens disposed behind the front lens 1, with a large number of light emitting diodes 4 arranged at predetermined intervals on the surface. A printed circuit board mounted in a matrix, 5 denotes the front lens 1.
Together with the back cover, it forms the lamp chamber. The light emitted from each light emitting diode 4 passes through the front lens 1 and is diffused by the diffusing lens 2 when illuminating the lens.

Since the dome part 6 is formed on the dome part 6 and the semiconductor chip is arranged below the center of the dome part 6 to improve the directivity of light, the axial direction of the light emitting diode 4 is illuminated most brightly, so that a difference in brightness occurs in the front lens 1. There was a problem with uniform lighting.

問題が生じる。Therefore, it is conceivable to arrange the light emitting diodes 4 closer together, but in that case, the number of diodes themselves will increase, which will cause an increase in cost, and if they are too close together, the amount of light emitted will decrease due to the heat generated by the diodes. Another problem arises in that the
