Description

  The present invention relates to an illuminating device that is installed at a position that can be reached by an operator, such as the bottom surface of a hanging cabinet of a kitchen.

  In a lighting fixture installed indoors, when the lighting fixture is installed on the ceiling in the room, the lighting fixture cannot be reached, so a switch for turning on and off is attached to the wall surface of the room. Moreover, when not only point extinguishing but also dimming by increasing / decreasing luminance, an operation unit for dimming is similarly attached to the wall surface (for example, see Patent Document 1).

Japanese Patent Laying-Open No. 2014-120208 ([0016], FIG. 2)

  In the above-mentioned conventional lighting fixture, the lighting fixture main body and the operation part for turning on and off and dimming are configured separately, and the operation part is attached to the wall surface. When a lighting fixture is installed, if the light is turned off or dimmed, the operator must move away from the installation location of the lighting fixture to the position where the operation part is attached. Occurs.

  Moreover, when operating the lighting fixture attached to such a kitchen, an operator's hand is often wet, and there is an annoyance that the hand must be wiped every time it is operated.

  Therefore, in view of the above problems, the present invention provides an illumination device that can be turned on / off and dimmed without the operator moving to the operation portion, and can be operated even when the hand is wet. Is an issue.

  In order to solve the above-described problems, a lighting device according to the present invention is installed in a position that can be reached by an operator, and in a lighting fixture having a light emitting unit therein, a capacitive proximity sensor is provided in the vicinity of the light emitting unit. It is provided that the operator's hand is brought close to the surface of the luminaire, and the dimming operation can be performed without bringing the hand into contact with the surface of the luminaire.

  In the said structure, since the proximity sensor is provided in the vicinity of the light emission part, when an operator operates, it is not necessary to move from the installation position of a lighting fixture. Further, since the operation can be performed without bringing the hand into contact with the surface of the lighting fixture, it is not necessary to wipe the hand every time the operation is performed even if the hand is wet.

  In addition, a plurality of detection units are arranged side by side as the proximity sensor, the luminance of the light emitting unit is set for each detection unit, and the luminance is set to the detection unit set to the detection unit where the hand is in proximity. You may make it light-control the brightness | luminance of a light emission part.

  Further, the moving direction and moving speed of the hand are detected, and when the moving speed is faster than a predetermined reference speed, light is emitted to the luminance set in the detecting unit corresponding to the detecting unit on the moving direction side from the position where the hand is separated. You may comprise so that a part may be dimmed.

  As is clear from the above description, the present invention is provided with a proximity sensor in the vicinity of the light emitting unit, so that it is not necessary to move from the installation position of the luminaire when the operator operates, and the luminaire is also provided. Therefore, even if the hand is wet, it is not necessary to wipe the hand every time it is operated.

The figure which shows the attachment state of a lighting fixture Diagram showing the internal structure of the lighting fixture The figure which shows an example of the operation by hand The figure which shows the other example of the operation by hand

  With reference to FIG. 1, 1 is an example of the lighting fixture by this invention, Comprising: It is installed in the bottom face B of the hanging cupboard installed in the kitchen. The luminaire 1 is provided with a main chamber portion 11 in which a light emitting portion, which will be described later, is housed, and a sub chamber portion 12 in which a control portion and a power source portion are housed.

  With reference to FIG. 2, the substrate 2 is accommodated in the main chamber portion 11. Eight detection units 31 to 38 are provided on the surface of the substrate 2, and each detection unit 31 to 38 is connected to the control unit 3. These detection units 31 to 38 function as electrostatic proximity sensors. When the operator's hand approaches any of the detection units 31 to 38, the control unit 3 determines which detection unit the hand has approached. Can be detected.

  In addition to the control unit 3, the sub chamber unit 12 houses a power supply unit 5, which converts external power into power of a predetermined voltage and supplies it to the control unit 3. The control unit 3 causes the LED 4 that is a light emitting unit to emit light by the supplied electric power.

  In the present embodiment, eight LEDs 4 are mounted in the vicinity of the detection units 31 to 38. Note that the number of LEDs 4 need not match the number of detection units 31 to 38. Moreover, although the brightness | luminance of LED4 is dimmed by the control part 3, all LED4 is dimmed to the same brightness | luminance in this Embodiment. However, the plurality of LEDs 4 may be divided into several groups and dimmed to different luminances for each group.

  An example of operation | movement of the lighting fixture 1 by the said structure is demonstrated with reference to FIG. As described above, since the proximity sensor is built in the luminaire 1, the operator simply brings the hand H close to the lower side of the luminaire 1 and does not contact the luminaire 1. 38 detects that the hand H has approached.

  The brightness was set to 8 levels of L1 to L8, and the detection units 31 to 38 were sequentially associated with the brightnesses L1 to L8. For example, when the hand H is brought close to the detection unit 31 located at the left end in the lighting device 1 when the lighting device 1 is turned off, the control unit 3 first switches from the turned-off state to the lighting state because the hand H approaches. At that time, all the LEDs 4 are caused to emit light at L1 having the lowest luminance so that the luminance L1 associated with the detection unit 31 is obtained.

  When the hand H is brought close to another detection unit in the lighting state, the control unit changes the luminance so that the luminance associated with the detection unit is obtained. For example, when the hand H is brought close to the detection unit 38 at the right end, the luminance of all the LEDs 4 is changed to the brightest luminance L8. The LED 4 is turned off when the hand H is released from the lighting fixture 1 after a state where the hand is kept close to any one of the detection units for a predetermined time.

  In the operation shown in FIG. 3, since the moving direction and moving speed of the hand H are not detected, the light intensity is adjusted to the brightness associated with the detecting unit disposed at a position where the hand is brought close to the hand H. As shown in FIG. 3, in addition to the dimming operation shown in FIG. 3, the moving direction and moving speed of the hand H may be taken into account.

  For example, when the hand H is brought close to the detection unit 38, the luminance becomes L8. When the hand H is slid to the left as it is and the hand H is lowered at the position of the detection unit 35, the luminance shown in the control shown in FIG. Becomes L5. However, when the movement speed from the detection unit 38 to the detection unit 35 is faster than a predetermined movement speed, the luminance is adjusted to L4 or L3 which is darker than L5. Thereby, in addition to the case where the brightness is accurately changed as shown in FIG. 3, the light control amount is increased even if the horizontal stroke of the hand H is short when it is desired to make it darker or brighter than the current state. be able to.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
