  The above-described conventional illumination device for passenger conveyors uses a fluorescent lamp as a light source, and it has been difficult to realize increase / decrease in illuminance by a control circuit. Further, when the fluorescent lamp is blinked, there is a problem that the life of the lamp is shortened. As described above, the conventional technology is easily restricted by the control of the light emission state.

  The present invention has been made from the above-described prior art, and an object thereof is to provide an illumination device for a passenger conveyor that can freely control the light emission state in accordance with a trigger signal.

  In order to achieve the above object, a lighting device for a passenger conveyor according to the present invention is disposed in a railing portion of a passenger conveyor and illuminates an entrance / exit and a step. A power supply circuit that supplies power to the light source unit, and a control circuit that is provided between the LED light source unit and the power supply circuit and controls the LED light source unit in response to a trigger signal are provided.

  In the passenger conveyor lighting device according to the present invention, in the invention, the control circuit controls the number of blinks and the blink cycle of the LED light source unit, increase / decrease in LED illuminance, and emission color according to the trigger signal. It is characterized by being possible.

  In the illumination device for a passenger conveyor according to the present invention, in the invention, the LED light source unit includes a plurality of light emitting elements and a light guide plate, and a plurality of the light emitting elements are provided at one or both ends of the light guide plate. An element is provided.

  In the passenger conveyor lighting device according to the present invention, the LED light source unit includes the light emitting element capable of emitting at least two colors.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to control a light emission state freely according to the trigger signal which was difficult with the conventional illuminating device, and an illumination function can be improved compared with the past. In addition, it is possible to suppress power consumption, thereby improving economic efficiency and extending the life of the apparatus.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments relating to a passenger conveyor lighting device of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an embodiment of a lighting device for a passenger conveyor of the present invention, FIG. 2 is a perspective view showing a state in which the embodiment is attached to a passenger conveyor, and FIG. 3 is an LED light source unit provided in the embodiment. It is a perspective view which shows an example.

  As shown in FIG. 2, the illumination devices 2 and 3 according to the present embodiment are arranged near the entrance 4 at the lower part of the balustrade 1 and under the moving handrail 5. As shown in FIG. 3, the LED light source unit provided in these illumination devices 2 and 3 is composed of a light emitting element 6, a light guide plate 7, and reflective dots 8 pasted or stamped on the light guide plate 7. . For example, one light emitting element 6 is provided at one end of the light guide plate 7. The light emitted from the light emitting element 6 is incident from the side surface portion of the light guide plate 7, and the light incident on the light guide plate 7 spreads while being repeatedly reflected in the light guide plate 7. At this time, when the light hits the reflective dots 8, the light is scattered there and emitted from the surface of the light guide plate 7.

  In the present embodiment, as shown in FIG. 1, a control circuit is provided between an LED light source unit including a light guide plate 7 having reflective dots 8 and a light emitting element 6, and a power supply circuit 9 that supplies power to the LED light source unit. 10 is provided, and the LED light source unit is controlled in accordance with a trigger signal 11 input to the control circuit 10. For example, the control circuit 10 can control the number of blinks of the LED power supply unit, the blinking cycle, the increase / decrease in LED illuminance, and the emission color.

  The power supply circuit 9 is provided with an electric plug 12 connected to an outlet (not shown). Moreover, the LED light source part which consists of the light emitting element 6 and the light-guide plate 7 is arrange | positioned so as to oppose the window 13 attached to the balustrade 1 part of a passenger conveyor. The light from the LED light source section illuminates the entrance / exit 4 and the step through the window 13.

  The illuminating devices 2 and 3 according to the present embodiment configured as described above are configured so that the control circuit 10 responds to the trigger signal shown in FIG. Since the number of blinks, the blink cycle, the increase / decrease in illuminance, and the emission color can be controlled, the light emission state of the LED light source unit can be freely controlled, and the illumination function can be improved. Further, it becomes possible to suppress power consumption, thereby improving the economic efficiency and extending the life of the apparatus.

  The LED light source unit shown in FIG. 3 has a configuration in which one generating element 6 is provided at one end of the light guide plate 7, but another light emitting element 6 is also provided at the other end of the light guide plate 7. You may make the structure provided.

  In addition, if a failure detection signal or a tampering detection signal is selected as a trigger signal, and the number of blinks, blink period, increase / decrease in illuminance, and emission color are set in advance in association with these trigger signals, the present embodiment By simply looking at the lighting state of the lighting devices 2 and 3, the failure status and the type of mischief can be easily grasped, and the maintenance can be simplified.

  FIG. 4 is a perspective view showing another example of the LED light source unit provided in the present embodiment. The LED light source unit shown in FIG. 4 is provided with a plurality of light emitting elements 6 at both ends of the light guide plate 7. The light emitting element 6 is composed of at least two colors. For example, the light emitting element 6 shown in FIG. 4 can emit light of three primary colors of red, blue, and green.

  As shown in FIG. 4, the LED light source unit can be configured to control increase / decrease in illuminance by controlling the number of lighting of the light emitting elements 6 by the control circuit 10. In addition, by combining the light emission intensity of each light emission color of the light emitting element 6 and the light emission timing, various colors can be generated, and the design can be improved. In addition, the alerting function can be improved, thereby contributing to ensuring excellent safety.

  The LED light source unit shown in FIG. 4 has a configuration in which a plurality of light emitting elements 6 are provided at both ends of the light guide plate 6, but a configuration in which the plurality of light emitting elements 6 are provided only at one end may be employed.

It is a block diagram which shows one Embodiment of the illuminating device of the passenger conveyor of this invention. It is a perspective view which shows the state which attached this embodiment to the passenger conveyor. It is a perspective view which shows an example of the LED light source part with which this embodiment is equipped.
