Abstract

An object is to provide a control apparatus of a showcase in which appropriate illumination having a high presentation effect can be realized by an LED illumination apparatus having a high durability against turning ON/OFF and capable of securing a predetermined illumination intensity even under an environment at a low temperature. The control apparatus controls a plurality of showcases so that display chambers where commodities are displayed are illuminated with LED illumination apparatuses, and includes a person detecting sensor provided in a showcase disposed in such a position that the approaching of any person can first be detected among the plurality of arranged showcases, so that the approaching of the person is detected. When the person detecting sensor detects the approaching of the person, the illumination intensities of all the LED illumination apparatuses of the plurality of showcases are increased.

Claims

1. A control apparatus which controls a plurality of showcases so that display chambers where commodities are displayed are illuminated with LED illumination apparatuses, comprising:

a person detecting sensor provided in a showcase disposed in such a position that the approaching of any person is first detected among the plurality of arranged showcases, so that the approaching of the person is detected,

wherein when the person detecting sensor detects the approaching of the person, the illumination intensities of all the LED illumination apparatuses of the plurality of showcases are increased.

2. The control apparatus of the showcase according to claim 1, wherein the illumination intensities of the LED illumination apparatuses are increased successively from the showcase provided with the person detecting sensor to the showcase disposed in a position far from the showcase provided with the person detecting sensor.

6. The control apparatus of the showcase according to any one of claims 1 to 5, wherein the plurality of showcases are provided in at least two rows so as to face each other, the person detecting sensor is provided in one of the showcases facing each other, and the control of the LED illumination apparatus by the detection of the person detecting sensor is executed with respect to both the LED illumination apparatuses of the pair of showcases facing each other.

7. The control apparatus of the showcase according to any one of claims 1 to 5, further comprising:

an illumination intensity sensor which detects the brightness of a surrounding area,

wherein the maximum illumination intensity of the LED illumination apparatus is determined in accordance with the brightness of the surrounding area detected by the illumination intensity sensor, and the LED illumination apparatus is brightened to the determined maximum illumination intensity or the second illumination intensity regarded as the maximum illumination intensity.

8. The control apparatus of the showcase according to any one of claims 1 to 5, wherein each showcase displays the commodities in the display chamber while cooling the commodities, and includes a temperature sensor which detects a temperature in the display chamber, and in a case where the temperature sensor detects that the temperature in the display chamber increases to a preset high temperature value, the illumination intensity of the LED illumination apparatus of the showcase provided with the temperature sensor is decreased.

3. A control apparatus which controls a plurality of showcases so that display chambers where commodities are displayed are illuminated with LED illumination apparatuses, comprising:

person detecting sensors provided in the plurality of arranged showcases, respectively, so that the approaching of any person is detected,

wherein when one of the person detecting sensors detects the approaching of the person, the illumination intensities of all the LED illumination apparatuses of the plurality of showcases are increased to a first illumination intensity, and the illumination intensity of the LED illumination apparatus of the showcase provided with the person detecting sensor which has detected the approaching of the person is increased to a second illumination intensity brighter than the first illumination intensity.

4. The control apparatus of the showcase according to claim 3, wherein the first illumination intensity is dark in the showcase installed in a position far from the showcase provided with the person detecting sensor which has detected the approaching of the person.

5. A control apparatus which controls a plurality of showcases so that display chambers where commodities are displayed are illuminated with LED illumination apparatuses, comprising:

person detecting sensors provided in the plurality of arranged showcases, respectively, so that the approaching on any person is detected,

wherein when one of the person detecting sensors detects the approaching of the person, the illumination intensity of the LED illumination apparatus of the showcase adjacent to the showcase provided with the person detecting sensor is increased to a first illumination intensity, and the illumination intensity of the LED illumination apparatus of the showcase provided with the person detecting sensor which has detected the approaching of the person is increased to a second illumination intensity brighter than the first illumination intensity.
