  1 to 4 show a first embodiment of the present invention, FIG. 1 shows a schematic perspective view of an LED security light, (a) is a front view, (b) is a rear view, and FIG. 2 is an LED security. FIG. 3 is a state diagram in which an LED security light is attached to an outlet body, and FIG. 4 is a state diagram illustrating a charging method using sunlight.

  1 and 2, an LED safety light 1 includes a unit body 2, a charging device 3, a battery 4 as a power storage means, a charge changeover switch 5 as a charge changeover means, and a lighting changeover switch 6 constituting a lighting means. It is configured.

  The unit body 2 is formed by combining the substantially box-shaped first unit body 7 and the second unit body 8, and the lengths of the unit bodies 2 are different from each other so that a step is formed on the front surface. A solar cell panel 9 is disposed on the front surface 7a of the first unit body 7, and a pair of plug blades 10 and 10 to be inserted into the plug insertion port of the outlet are disposed on the rear surface 8a of the second unit body 8. It is installed.

  Furthermore, a plurality of light emitting diodes (LEDs) 11 are arranged on the lower side surface 7 b as one side surface of the first unit body 7. The light emitting diode 11 is covered with a translucent resin, for example, an epoxy resin 12. Further, a charging changeover switch 5, a lighting changeover switch 6, and a nightlight changeover switch 13 are arranged on the side surface 7 c of the first unit body 7. These change-over switches 5, 6 and 13 are in the on state when blacked out in the figure.

  The charging device 3 is accommodated in the unit body 2 and, as shown in FIG. 2, a rectifying / smoothing circuit 15 including a rectifying device 14 and a smoothing capacitor C1, and a current-limiting circuit connected to the positive electrode side of the smoothing capacitor C1. A resistor R1 is provided. The input side of the rectifier 14 is connected to the plug plug blades 10 and 10. The charging device 3 is configured such that the plug plug blades 10 and 10 are inserted into the plug insertion ports of the outlet, and an AC voltage (AC 100 V) is applied to the plug plug blades 10 and 10, thereby causing a direct current across the smoothing capacitor C <b> 1. Voltage is generated and output.

  Both ends of the smoothing capacitor C1 are connected to the normally closed contacts Ry1-b1 and Ry1-b2 of the relay Ry1 (not shown) via the resistor R1, and further the normally closed contact Ry2 of the relay Ry2 (not shown). It is connected between both ends of the battery 4 via b1, Ry2-b2. The solar cell panel 9 is connected to the normally open contacts Ry1-a1 and Ry1-a2 of the relay Ry1 through a current limiting resistor R2.

  The battery 4 is accommodated in the unit body 2 and connected to the light emitting diode 11 via a normally open contact Ry3-a1 of a relay Ry3 (not shown) and a current limiting resistor R3. The battery 4 is charged by the DC voltage output from the charging device 3 when the common contacts Ry1-c1, Ry1-c2 of the relay Ry1 are connected to the normally closed contacts Ry1-b1, Ry1-b2, and is shared. When the contacts Ry1-c1 and Ry1-c2 are connected to the normally open contacts Ry1-a1 and Ry1-a2, they are charged by the DC voltage output from the solar cell panel 9.

The control circuit 16 includes a CPU, a ROM, and a RAM (not shown), and further includes a timepiece (not shown), relays Ry1 to Ry3, an internal power source, and the like.

  When charging changeover switch 5 is off, common contacts Ry1-c1 and Ry1-c2 of relay Ry1 are connected to normally closed contacts Ry1-b1 and Ry1-b2. Therefore, the battery 4 is charged from the charging device 3. When the charging changeover switch 5 is turned on, the control circuit 16 energizes a relay coil (not shown) of the relay Ry1 so that the common contacts Ry1-c1, Ry1-c2 are normally opened contacts Ry1-a1, Ry1. -Connect to a2. Thereby, the battery 4 is charged from the solar cell panel 9. The charging changeover switch 5 and the control circuit 16 constitute charge switching means for connecting either the solar battery panel 9 or the charging device 3 and the battery 4.

  When the lighting changeover switch 6 is off, the control circuit 16 does not energize the relay coil (not shown) of the relay Ry3, and the normally open contact Ry3-a1 is in the open state.

The light emitting diode 11 is turned on using the battery 4 as a power source. The lighting changeover switch 6, the control circuit 16, and the resistor R1 constitute lighting means for lighting the light emitting diode 11 using the battery 4 as a power source.

  When the night light changeover switch 13 is turned on, the control circuit 16 energizes the relay coil of the relay Ry3 during the night, for example, from 17:00 to 8:00 on the next day. Thereby, the light emitting diode 11 is automatically turned on using the battery 4 as a power source at night. If the night light selector switch 13 is turned off, the light emitting diode 11 is not automatically turned on.

Thereby, the LED security light 1 can be used as a nightlight. Moreover, it can be used as a portable electric light by removing the LED security light 1 from the outlet when a power failure occurs at night.

  When the night light selector switch 13 is turned off, the light emitting diode 11 is not turned on at night. For example, when a power failure occurs at night, the LED safety light 1 is removed from the outlet body 17 and the lighting changeover switch 6 is turned on, so that the light emitting diode 11 is turned on using the battery 4 as a power source. Thereby, the LED security lamp 1 can be used as a portable electric light.

  And when a power failure does not recover, such as at the time of a disaster such as an earthquake, the charging changeover switch 5 is turned on to connect the battery 4 and the solar battery panel 9. And as shown in FIG. 4, the solar cell panel 9 is exposed to sunlight. Thereby, the battery 4 is charged from the solar cell panel 9. Then, by turning on the lighting changeover switch 6, the light emitting diode 11 is turned on.
