であった。←) Conventional technology As shown in Japanese Utility Model Publication No. 65-9048, conventional lighting lamps of this type charge a secondary battery using a solar cell, and set the timer from that time when the surrounding area becomes dark due to sunset. The lamp is turned on for a predetermined period of time (for example, 5 hours), and the lamp is turned off after the set period of time has elapsed, making it convenient for lighting in places where commercial AC power cannot be used.

Since the lights turn off after the set time has elapsed, when used for purposes such as street lights, they will not be illuminated late at night after the lights have been turned off, and this will pose safety and crime prevention problems for passersby on dark roads at night. be. In addition, although the above configuration can reduce power consumption compared to a configuration in which the lights are turned on continuously from sunset to dawn, the power consumption is still quite large, especially when the timer setting time is increased in view of the above problem. In order to cover the power consumption, solar cells and secondary batteries were required to be quite large, resulting in high costs.

The output voltage of the solar cell (1) is sufficiently high, and the solar cell (1) charges the secondary battery (2) with its output power. Also, the output voltage of the solar cell (1) at this time is higher than the signal level of the reference signal source (6), and the output of the first comparator (7) is at a high level (hereinafter referred to as high level t-H, The low level is abbreviated as L], and the first timer circuit (9) does not operate and its output C1, that is, the first control signal is L. On the other hand, the infrared detector (121) The field of view is monitored through the detection window C! 41, and when the presence of a person is detected there, the second comparator (14 to However, when the output of the illuminance detection section (5) is H,
The output of Q51 is L, the output of the second timer circuit is e,
That is, the second control signal is L regardless of the detection result of the infrared detector (1z. At this time, the output f of the or game) 181 is also L, so the transistor field is not conductive, and when the surroundings are bright, it is With or without the lamp (
3) is off.

られf?:、電力によりで点灯する。When the surrounding environment becomes dark due to sunset and the output voltage of the solar cell (1) decreases, the secondary battery (2) is no longer charged. When the illuminance detection unit (5) detects that the ambient brightness has decreased based on the comparison result between the output pressure of the solar cell (1) and the reference signal source (6), the first comparator (7) The output signal changes from H to L. The first timer circuit (9) of the timer section (8) starts operating when the output falls 9, and the first timer circuit (9) of the timer section (8) starts operating at the falling edge of the output (9), and the first timer circuit (9) remains in operation for the set time 1) (for example, 2 hours). Let the control signal be H. When this first control signal is H, the output of the OR gate (l& is H regardless of the detection result of the infrared detector (17J)), the transistor peak is conductive for the set time t1, and the lamp (3) is turned on. The light is lit by the power stored in the secondary battery (2).

The control signal returns to L, the output of the OR gate σ& becomes L, and the lamp (3) goes out, but even after that, the output of the illuminance detection section (5) remains L while the surrounding environment is dark. Therefore, during this period, when an H signal is applied to the output d of the second comparator (2) as a result of the detection by the infrared detector dz, the output of the anti-game ttts becomes H, and the second timer circuit (1
61 starts operating, and the second control signal becomes H for the set time tz (for example, 2 minutes). This second control signal is H
Also when this is the case, the output I of (or game) file becomes H, and the lamp (3) lights up for the set time t2.

て通行人などの注意も喚起され防犯上も望ましい。That is, according to Honomizo Sei, the lamp (3) is turned on continuously only during the time t1 when there are many people passing by after sunset, and after that, the lamp (3) is turned on continuously during the time t1 when there are many people passing by, and after that, the lamp (3) is turned on continuously during the time t1 when there are many people such as passersby.
It is possible to only turn on the light. Therefore, the lamp (3) is not left on continuously until late at night when there are few people, so power consumption is reduced. Furthermore, when there are passersby late at night, the lamp (3) can be turned on each time to ensure the safety of the passerby, and the lamp (3) can also be turned on to attract the attention of passersby, which is desirable from the viewpoint of crime prevention.

。For example, for a conventional configuration that uses a 10W fluorescent lamp as a light source and lights continuously for 5 hours after sunset, a solar cell + 1
) must have a maximum output Pmax of at least 25W. On the other hand, if a 10W fluorescent lamp is turned on continuously for 2 hours (t1) after sunset according to the present invention, and it is turned on 12 times for 2 minutes (t2) due to late-night passersby, the solar cell will be j need to have a pmax of 12W.Therefore, the solar cell fi+ or the secondary battery (2) may be small and inexpensive; There are no longer very strict requirements for strength such as wind resistance, making it possible to create lighting lamps that are generally cheaper.Furthermore, if solar cells (1) become smaller, there will be fewer restrictions on design and installation locations.

意の長さの時間だけ点灯する構成が可能となる。In this embodiment, the illuminance detection section (5) is connected to the solar cell t.
Although the brightness is detected using the output of l+, a separate illuminance sensor may be provided. Also, if the detection device part from the infrared detector U21 to the second comparator U41 is replaced with one that continues to output the H signal while there are people around, the second timer circuit mark can be omitted and the This allows for a configuration in which the lights are turned on only for an arbitrary length of time when there are people present.

い。Also, if the timer section (8) is omitted, IJfftt will be eliminated when the lamp is turned on continuously after sunset, and the lamp (3) will frequently flash and return at night when there are people around. 91 This is not desirable because it may cause discomfort to passersby, and if a fluorescent lamp is used as the lamp (3), frequent flashing may shorten the life of the lamp.
