摘要： PROBLEM TO BE SOLVED: To obtain an autonomous system capable of automatically performing change- over into previously charged power when the main power source of a traffic light is interrupted, flickering red or yellow high luminance light emitting diodes while restricting power consumption to the minimum by a control circuit, attaining the smoothness of traffic on roads and railroads and securing the power source of the traffic light, and not depending on an alternative generator in an emergency. SOLUTION: Charging is normally performed in the large capacity aluminum electrolytic capacitor 7 of an emergency time power source circuit for a light emitting diode traffic signal which is incorporated in a traffic light body. When power is interrupted, a relay 1 in a unit 13 flickers the red or yellow signal light 12. A current charged in the capacitor performs the intermittent lighting of the light emitting diodes of the traffic light 12 by a chopper circuit 15 through the use of control waveforms (a waveform turning on/off at about one second interval which is the intermittent wave of several micro seconds to tens of micro seconds) which are generated by a multi-vibrator 14. Then power consumption in the large aluminum electrolytic capacitor 7 is decreased to about a quarter.

摘要： PROBLEM TO BE SOLVED: To prevent the weak lighting of an LED by the induction without using a transformer, in a signal light using an LED as the lighting source. SOLUTION: An induction lighting preventive circuit IPC having a trigger circuit 1 and a switch circuit 2 is provided between the color lights 8G, 8Y, and 8R of a signal lamp, and their power source circuit 3. The trigger circuit 1 has a Zener diode ZD, it is operated by a regular signal control voltage, and delivers its output to the switch circuit 2. The switch circuit 2 is a photo MOS relay FMR, it operates by making the output of the Zener diode ZD as the trigger, and inputs the input regular signal control voltage to the color light 8G, 8Y, or 8R. The color light 8G, 8Y, or 8R is an LED unit, and it emits the light by the regular signal control voltage, but not weak lighted by the induction voltage less than the regular signal control voltage.

SOLUTION: Electric circuits 11a of a yellow light emitting unit 9b and electric circuits 11b of a green light emitting unit 9a are respectively and separately connected to an insulating transformer 13 through rectifiers 12, and emit the light when electric power is supplied from an AC power source, but the respective electric circuits 11a of the yellow light emitting unit 9b and the respective electric circuits 11b of the green light emitting unit 9a are connected in series to each other, and the insulating transformer 13 connected to the yellow light emitting unit 9b supplies electric power to the respective rectifiers 12 and 12 by transforming AC 100V to 200V. Therefore, DC 100V is respectively supplied to the electric circuits 11a and 11b of the two light emitting units 9a and 9b whose impedances are equal to each other, and luminous intensity of the yellow light emitting unit and the green light emitting unit can be secured.

摘要： PROBLEM TO BE SOLVED: To produce the satisfactory white railway signals by means of the light emitting diodes LED having the small heating value and current consumption, the high resistance to vibrations and also a long service life by mixing a small number of green LED among the yellow LED. SOLUTION: A round substrate 12 includes many yellow LED 13b which are concentrically placed from the center of the substrate 12 toward its outer circumference together with a small number of green LED 13a which are concentrically placed in circles among the LED 13b and also partly scattered in the inner part of the substrate 12 respectively. The number of LED 13b exceeds five times as much as the number of LED 13a, and both LED 13b and 13a are arranged in six laps from the center of the substrate 12. The LED 13a are arranged at the parts near the center of the substrate 12 from the 3rd outer lap. In such a way of LED arrangement, the substrate 12 looks white as a whole.
