BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows an external configuration of a lighting fixture mounting base 10 according to an embodiment of the present invention, in which (a) is a front view, (b) is a bottom view, and (c) is a perspective view showing a use state. FIG.
As shown in FIG. 1 (c), the lighting fixture mounting base is provided on a mounting surface to which the lighting fixture is to be mounted, such as a wall surface, a ceiling, a floor, etc. The lighting device is provided between the lighting device and the lighting device, and can be fixed to a wall surface by a fixing tool such as a screw, and can be fixed to the lighting device.
[0011]
As shown in FIG. 1B, the lighting fixture mounting base 10 includes a human sensor 11 and a light / dark sensor 12. The human sensor 11 is an optical sensor having a sensitivity in an infrared region, and detects that a human is approaching. The light / dark sensor 12 is a sensor having sensitivity in the visible light region, and detects that the surrounding brightness has become equal to or less than a predetermined threshold.
[0012]
A timer switch 13 and a light / dark reference switch 14 are provided beside the human sensor 11 and the light / dark sensor 12.
The timer switch 13 is for switching the time for which the lighting of the lighting apparatus is kept on, regardless of the detection signal of the human sensor 11, after the brightness sensor 12 determines that the surrounding brightness is equal to or less than a predetermined threshold value. It is. As shown in FIG. 2A, for example, the timer switch 13 can be switched between three stages of “9h”, “6h”, and “off”.
[0013]
When the timer switch 13 is set to “9h”, after the light / dark sensor 12 determines that the surrounding brightness is equal to or less than a predetermined threshold, the lighting of the lighting device 20 is turned on for 9 hours. Continuous lighting is performed regardless of the eleven detection signals. As a result, in a place where people enter and exit sharply, the shortening of the life of the light bulb and the fluorescent lamp due to the frequent lighting on / off is prevented.
When the timer switch 13 is set to “6h”, the continuous lighting time becomes 6 hours. When the timer switch 13 is set to “off”, the lighting is turned on / off every time the detection signal of the human sensor 11 is switched. . If people do not enter and exit intensely, turning off the timer switch 13 can save electricity bills.
[0014]
The light / dark reference switch 14 switches the brightness (illuminance) as a light / dark judgment criterion in the light / dark sensor 12, and as shown in FIG. 2 (b), includes three of "test", "bright" and "dark". It can be switched between stages. When the light / dark reference switch 14 is set to “bright”, the illumination of the lighting device 20 is turned on when the surroundings are dim. When the light / dark reference switch 14 is set to “dark”, the illumination of the lighting fixture 20 is turned on after the surroundings have become considerably dark. When the light / dark reference switch 14 is set to “test”, the sensing area of the human sensor 11 can be confirmed.
