摘要：本発明によれば、たとえ外側レンズ（５２）を同時に交換する必要があるとしても、白熱電球（５）とＬＥＤ灯（３０）とを僅か数分で交換することができる。より効率的な高パワーＬＥＤをより少数使用することによって、設置時間を短縮し、レフレクタを使用せずにＬＥＤの光出力をレンズ（５２／５３）に直接投射し、そしてＬＥＤ灯（３０）を用いて改装する際に交通信号灯３０からレフレクタ及びソケットコネクタを取り外して処分する必要性を排除することができる。
摘要翻译：一种用于改装传统交通信号灯的大功率LED灯和方法。 LED灯包括壳体，设置在壳体中的电源，安装到壳体中的基本上平面的安装表面并电连接到用于产生发散光的电源的多个LED以及从壳体延伸的螺纹电连接器。该方法包括用LED灯替代传统的白炽灯泡，并且在交通信号灯内安装菲涅耳透镜，该信号灯准直并仅填充并照亮交通信号灯的外部透镜。

摘要： PROBLEM TO BE SOLVED: To provide a signaling light which can be recognized easily by the colorblind. SOLUTION: The signal light is composed of a first white light source 241, a second white light source 242, a third white light source 243, a first cover lens 221 transmitting light of a first wavelength spectrum from among lights emitted from the first white light source 241, a second cover lens 222 transmitting light of a second wavelength spectrum from among lights emitted from the second white light source 242, a third cover lens 223 transmitting light of a third wavelength spectrum from among lights emitted from the third white light source 243, first auxiliary light-emitting bodies 231, 231b, 231c,..., 231h emitting light of a fourth wavelength spectrum arranged at a peripheral part of the second cover lens 222, and second auxiliary light-emitting bodies 232a, 232b, 232c,..., 232h emitting light of a fifth wavelength spectrum arranged at a peripheral part of the second cover lens 222.

摘要： PROBLEM TO BE SOLVED: To improve performance and function for substituting a filament type bulb. SOLUTION: This LED signal bulb is provided with an attaching and detaching part 10 having a base 12 interchangeable with a railway signal lamp and a connecting contact part 11, an LED light emitting part 70 having plural LEDs 71, 72, and a rectifying circuit 30 interposed in a power feeding path extending from the connecting contact part 11 to the light emitting part 70. This bulb is provided with a smoothing circuit 40 interposed between the rectifying circuit 30 and the light emitting part 70, a driving circuit 50 for detecting the supply current to the light emitting part 70 and controlling the same constant, a detecting means 60 for detecting the existence/absence of the supply current, and a current application amount switching means 20 for switching the current application amount of the connecting contact part 11 between a large value and a small value according the above detection result. The LED 72 is reverse to the LED 71. Thus, even if the input power supply voltage varies, the light intensity is kept constant so that it can be applied to a signal in which when two lamps are used in series, and one is extinguished due to disconnection trouble, the other lamp is also extinguished to need back light.

摘要： PROBLEM TO BE SOLVED: To radiate heat concentrated by miniaturizing a base in a condition where no heat conduction is dispersed, in a LED signal light adopting as a light source a LED lamp consuming large electric power with increased heat energy per piece. SOLUTION: In this LED signal light 1, a base 3 to hold a LED lamp is formed as a self-sustaining structure of a metallic plate having an enough thickness to conduct heat when it is turned on, the base 3 mounted with the LED lamp 2 is placed on a radiating fin 4 through an insulating heat conductive sheet 5, and the base 3 and the insulating heat conductive sheet 5 are mounted by holding them between a pressure plate 6 of resin serving also as a reflecting mirror and the radiating fin and bringing them into pressure contact with the radiating fin by the pressure plate.
