Description

  The present invention relates to a lighting fixture that saves energy by controlling lighting of a lighting lamp by sensor detection, and more particularly to a lighting fixture having a structure in which a sensor can be separated from and replaced with a lighting fixture.

  A conventional lighting fixture with a sensor has a structure in which the sensor is built into the lighting fixture. For example, the lighting fixture is turned on / off or dimmed by detecting the presence / absence of a person by the sensor. Lighting power can be reduced. However, for example, when a part of the work space where a general lighting fixture without a sensor is installed is used as a passage by changing the layout, it is desired to turn on the lighting fixture only when a person passes by sensor control. In addition, it is necessary to replace a general lighting fixture already installed with a sensor-equipped lighting fixture together with the main body.

  Therefore, there is known a lighting fixture that includes a function plug having a sensor control function and the like, and an attachment portion through which the function plug can be inserted and removed, and in which the function plug can be replaced depending on the application (for example, see Patent Document 1). With this lighting fixture, when it is desired to provide the lighting fixture with a sensor control function by changing the layout as described above, a plug-in sensor, which is a type of functional plug having a sensor control function, is simply attached to the mounting portion. There is no need to replace the luminaire body.

  This type of lighting fixture is shown in FIGS. The lighting fixture 18 includes an illumination lamp 19, a plug-in sensor 20 for lighting control, and a sensor mounting portion 22 for detachably attaching the plug-in sensor 20 to the fixture housing 21. The part 22 has a connector part 23 for holding the plug-in sensor 20 and supplying power.

  As shown in FIG. 15 (a), when sensor control is not required, the plug-in sensor 20 is removed from the sensor mounting portion 22, and as shown in FIG. The plug-in sensor 20 is attached to the attachment portion 22. However, since the outer shape of the luminaire 18 is greatly changed by the attachment / detachment of the plug-in sensor 20, it is not preferable in terms of design. Further, when the plug-in sensor 20 and the sensor mounting portion 22 are wired, when the plug-in sensor 20 is removed from the sensor mounting portion 22, the connector portion 23 provided on the sensor mounting portion 22 is connected to the lighting fixture 18. It is not preferable for safety because it is exposed on the surface of the film.

In addition, as a sensing function for sensor control, there are mainly human detection and brightness measurement. Human detection devices include means for detecting movement of heat rays, means for detecting moving objects by reflection of ultrasonic waves, etc., and brightness measurement devices include means for measuring reflected light from the irradiated surface with a light receiving device. Is used. In both cases, a space depending on the optical design is required in consideration of the detection area and the like, so the sensor mounting portion 22 has a certain thickness, and there is a limit to making it thin.
JP 2002-110376 A

  The present invention has been made to solve the above-described problem, and by reducing the change in the appearance of the lighting fixture between the state in which the plug-in sensor is removed from the sensor mounting portion and the state in which the plug-in sensor is mounted on the sensor mounting portion. An object of the present invention is to provide a sensor detachable luminaire that is improved in design, and that is improved in safety by preventing the connector portion of the sensor mounting portion from being exposed on the surface of the luminaire.

  In order to achieve the above object, the invention of claim 1 includes an illumination lamp, a sensor for controlling lighting of the illumination lamp, a sensor mounting portion for detachably attaching the sensor to an instrument housing, In the sensor detachable lighting fixture including the above, a cover portion that is attached to and detached from the sensor mounting portion so as to cover the sensor in a state where the detection portion of the sensor is exposed is provided.

  According to a second aspect of the present invention, in the lighting apparatus according to the first aspect, the cover portion includes a through-hole at a location facing the detection portion of the sensor, and the sensor attachment portion supplies power to the sensor. The connector part is provided, The said connector part is arrange | positioned in the position which does not contact the normal line of the said through-hole.

  According to a third aspect of the present invention, in the lighting apparatus according to the first aspect, the detection unit of the sensor includes a convex detection unit for detecting the presence of a person and a planar detection unit for detecting brightness. And the cover portion has an opening for sliding the sensor from the side to be inserted, and the convex detection portion when the sensor is slid from the opening and inserted into the cover portion. And a notch for avoiding interference with.

  According to the first aspect of the present invention, the cover portion is exposed on the outermost surface of the lighting fixture regardless of whether the sensor is attached to the sensor attachment portion or the sensor is detached from the sensor attachment portion. Therefore, the appearance of the lighting fixture does not change, so that the design is improved, and the connector portion of the sensor mounting portion is not exposed by being covered with the cover portion, so that safety is improved.

  According to the second aspect of the present invention, even when the user inserts a finger from the through hole of the cover portion when the sensor is detached from the sensor mounting portion, it is difficult to touch the connector portion of the sensor mounting portion. improves.

  According to the invention of claim 3, since the sensor is supported and supported by the cover portion, the sensor can be prevented from falling. Moreover, since it is not necessary to cover the convex part of a detection part by a notch in a cover part, since the magnitude | size of a cover part can be made small by that, the design property improves. Furthermore, since the cover part does not have a movable part etc., durability improves.
