    • A plurality of cellular concave mirror surfaces are formed on a plate-like reflector unit, and a plurality of light-emitting diodes are disposed on these cellular concave mirror surfaces to jointly form a colored light source. Connection wirings to be connected with a power supply source are provided on a substrate laminated with the reflector unit. A lamp base of a conventional type may be coupled to the substrate for being electrically connected to the wirings. This colored light source can provide a single or multiple color displays. Improved shadow pattern display can be provided by forming a complementary color pattern on a front cover lens. Letter, symbol or pattern display can be provided by selectively arranging light-emitting diodes on the reflector unit. In case the above-mentioned light source is used as a traffic signal device, power dissipation and maintenance care are reduced by the light-emitting diodes having low power consumption and long service life, and high security of the traffic is assured by the elimination of false indications caused by external lights.
    • 在板状反射器单元上形成多个细胞凹面镜面,并且在这些细胞凹面镜面上配置多个发光二极管,共同形成着色光源。 在与反射器单元层叠的基板上设置与电源连接的连接配线。 常规类型的灯座可以耦合到基板,用于电连接到布线。 这种彩色光源可以提供单个或多个彩色显示器。 可以通过在前盖透镜上形成补色图案来提供改进的阴影图案显示。 可以通过在反射器单元上选择性地布置发光二极管来提供字母,符号或图案显示。 在将上述光源用作交通信号装置的情况下,通过具有低功耗和长使用寿命的发光二极管来降低功耗和维护保养,并且通过消除交通信号来保证高安全性 外部灯光引起的虚假指示。
