[Action]

The power supply device including the outdoor lighting means of the present invention charges the secondary battery (3) prior to its use.
When inserting the plug (6) into the outlet (5) of the AC power supply, a light emitting diode for charging display (red light emission)
(9 ') or the charge instructing light emitting diode (9) emits light. You can check "Start charging". The voltage of the secondary battery (3) reaches a peak after a required time (about 7 hours in the experiment of the present inventor) from the start of charging (see FIG. 5). Graph showing the relationship with the charging time (T) "), at this peak time, the charging voltage detecting means (12) is activated, and the light emitting diode (green light emitting) (10) for instructing charging completion emits light. , The state of “sufficient charge” can be confirmed. The user removes the plug (6) from the outlet (5) after the light emission of the light emitting diode (10) is turned on. When charging is continued without removing the plug (6), a small amount of current flows in a so-called trickle state in the case of a nickel-cadmium battery or the like. In the case of a sealed lead battery, charging is stopped by the operation of the current cutoff means (16) in order to prevent performance degradation due to overcharging (see FIG. 21). reference).

After use for a predetermined time, the battery discharge lower limit voltage detecting means (7)
When the voltage of the secondary battery (3) falls below a predetermined voltage due to the presence of the power supply, the power supply stopping means (13) operates to turn off the lighting circuit. When the detection means (7) is provided with hysteresis and the IC is used, even if the voltage of the secondary battery (3) recovers to a level suitable for lighting after the stop of lighting, the OFF state of the lighting circuit is maintained, Thus, the damage of the secondary battery (3) is prevented.
