Description

  The present invention mainly relates to an illumination lighting device for a street lamp group, and more particularly to an illumination lighting device for avoiding a momentary interruption due to a large inrush current due to simultaneous lighting of a lighting device group.

  In a lighting device equipped with a conventional light sensor type lighting device, ambient brightness is measured using a light sensor, and lighting is performed when the ambient brightness becomes a certain value or less. Moreover, in the lighting equipment provided with the timer type lighting device, the lighting is performed by the self-timed timer.

Conventionally, as an illuminating device that realizes energy saving, as shown in Patent Document 1, a device that detects ambient brightness and controls the illuminance to be substantially constant, a device that uses natural light as illumination, a time A device that manages lighting time according to a schedule is known. Those that control to keep the illuminance substantially constant can save energy by not increasing the light output more than necessary, and those that are managed by the time schedule can be turned on during times when lighting is unnecessary. Energy saving was realized by turning off the lights.

  However, in lighting equipment equipped with an optical sensor type lighting device, the illuminance sensitivity of the optical sensor is different from the sensitivity that the human eye feels dark. This is difficult to see from the viewpoint of saving energy. In addition, the timer-type lighting device has a drawback that it takes time to change the lighting time for each season and a disadvantage that the delay and advance of timekeeping are accumulated and the deviation becomes large. Further, in the light sensor type and timer type lighting device, the lighting device group is turned on all at once, resulting in a large inrush current at the same time, causing a momentary interruption.

  The present invention has been made in view of the above problems, and its object is to eliminate the above problems.

In order to solve the above problems, the present invention has the following features.
[1] An illumination lighting device according to the present invention supplies a power to a receiving unit that receives radio waves including time information, a control unit that instructs lighting of a lighting device, a random number generation unit that generates a random number, and a lighting device. A lighting unit including a power supply unit that performs a predetermined time based on a random number generated by the random number generation unit when the time received by the reception unit reaches a predetermined time. The power supply unit is instructed to supply power to the lighting device.
[2] The illumination lighting device according to the present invention supplies power to the illuminance sensor unit that measures ambient illuminance, a control unit that instructs lighting of the illumination device, a random number generation unit that generates random numbers, and the illumination device. An illumination lighting device including a power supply unit, wherein the control unit is based on a random number generated by the random number generation unit when the ambient illuminance measured by the illuminance sensor unit becomes a predetermined illuminance. The power supply unit is instructed to supply power to the lighting device after a predetermined time.

  According to the present invention, since simultaneous lighting of all lighting devices is avoided by the random number generation unit and the control unit, instantaneous interruption due to simultaneous large inrush current due to simultaneous lighting can be avoided. In addition, lighting and extinguishing of the lighting device group can be made stable and accurate, and the trouble of changing the time setting for turning on and off every season can be saved.

  As an example of an embodiment of the present invention, an illumination lighting device will be described with reference to the drawings.

  As shown in FIG. 1, an illumination lighting device according to the present invention includes a receiver 1 that receives radio waves including time information (month, date, hour, minute, second) or an illuminance sensor unit 2 that measures ambient illuminance, and lighting equipment. It has the control part 4 which performs an instruction | indication, the random number generation part 6 which generates a random number, and the power supply part 8 which supplies a power supply to the illuminating device 10. FIG.

  Here, when the time received by the receiving unit 1 becomes a predetermined time, or when the ambient illuminance measured by the illuminance sensor unit 2 becomes equal to or lower than the predetermined illuminance, the control unit 4 The random number generator 6 is activated, and the random number generator 6 generates a random number. Then, after a predetermined time based on the output value of the random number generated by the random number generation unit 6, the power supply unit 8 is instructed to supply power to the lighting device 10, and the lighting device 10 is turned on. The power supply instruction to the lighting device 10, that is, the lighting instruction may be performed for each lighting device, for example, the lighting device is divided into several lighting device groups depending on the installation location, etc. A lighting instruction may be issued for each lighting device group. Thereby, the instantaneous interruption by simultaneous simultaneous lighting which became a problem in the lighting equipment provided with the conventional lighting device can be avoided.

  The brightness at a certain time is determined by the location and season (date), and it is customary to know when to turn on the streetlight. For example, in a specific place, it is only necessary to light up at 18:00 in summer and at 16:30 in winter. A radio wave including time information, which is a standard radio wave transmitted from a standard radio wave transmission station, includes data on the month, date, hour, minute, and second. Therefore, the control unit 4 can accurately grasp the time when the lighting device of that day should be turned on.

  When lighting the lighting device, in a specific place, in summer, 18:00 is a certain time (predetermined time), and each lighting device group has a predetermined value based on the output value of the random number generated by the random number generator 6. For example, one lighting device group is lit at 18: 00: 01.50 seconds, and another lighting device group is lit at 18: 00: 02.00 seconds.

  For example, when a lighting lighting device according to the present invention is shipped from the factory, it is possible to easily set the lighting time according to the land at the installation site by providing several regional setting selection switches.

  In addition, when lighting device groups are turned on by the illuminance measured by the illuminance sensor unit 2, the individual illuminating device groups are defined as a point in time when the illuminance of the illuminance sensor unit 2 reaches a value to be lit (predetermined illuminance). The light is turned on after a predetermined time based on the output value of the random number generated by the random number generator 6.

  As mentioned above, although the illumination lighting device which avoids the momentary disconnection of the present invention has been described in detail, the present invention is not limited to the above-described embodiment, and various improvements and modifications may be made without departing from the spirit of the present invention. Of course it is good.

It is a block diagram which shows one Embodiment which concerns on the illumination lighting device of this invention.
