している。2. Description of the Related Art Light-emitting diodes (LEDs) generally have a longer life than light bulbs that have been conventionally used as light sources for traffic signal lamps, but have a lower luminance, and therefore have a lower luminance. By arranging a large number of diodes in parallel, it is possible to obtain luminance that can be used practically for traffic signals.

それがあった。In general, a light emitting diode has a property that the directivity of the emitted light is strong. For this reason, in the above-mentioned conventional traffic signal lamp, even if there is a slight shift in the direction of a large number of light emitting diodes, the desired brightness may not be obtained in front. In addition, traffic signal lamps using light-emitting diodes have the disadvantage that they tend to glow white, especially when exposed to sunlight such as the West, and therefore, the phantom ratio in the signal lamp common standard (the unit that is lit and the light reduction) However, there is a problem that the ratio of the luminance value of the brighter unit to that of the unit that is performing the operation becomes lower. For this reason, there is a possibility that when the shining sun or the like is incident in addition to the low luminance, it becomes very difficult to see.
