Description

  The present invention relates to a lighting device that is controlled by receiving a radio remote control signal.

  2. Description of the Related Art Conventionally, there has been known a lighting device in which an antenna is arranged far away from a fixture body (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2008-204922 (FIG. 1, paragraph numbers 0015 and 0016)

  Conventionally, there has been an infrared remote controller as a lighting device operated by a remote controller. In such an illuminating device, when a button of an operation remote control transmitter is operated, a signal corresponding to the instruction content of the button is transmitted from an infrared lamp mounted on the remote control transmitter. And the infrared signal from the remote control transmitter is received and analyzed by the infrared light receiving unit which receives the infrared signal provided in the fixture body of the lighting device, and the lighting circuit is controlled.

  The infrared light receiving unit installed in such an illumination device receives the infrared wavelength contained in the light of the lamp as noise, so the sensitivity is reduced from the original reception performance, and the illumination is mounted with a light source containing infrared light. There is a limit in improving the signal / noise ratio of mounting the infrared light receiving unit inside the device. Therefore, securing a place that is less affected by the incidence of the lamp light and that can receive infrared signals from any external direction is a limitation of downsizing and thinning of the instrument body. For example, the problem can be solved by mounting an infrared light receiver on the outside of the instrument body, which is less affected by the lamp light, but the outer shape of the instrument body becomes large and there are restrictions on the design. Further, the infrared signal transmitted from the remote control transmitter is generally strong in directivity, and the signal may not reach unless the transmitter is transmitted directly to the infrared light receiving unit.

  In order to solve such a problem, an illumination device equipped with a radio remote controller that transmits a high-frequency signal from an antenna and replaces the receiving part of the instrument body with an antenna instead of an infrared lamp of a remote control transmitter has been proposed. Yes. In such a conventional lighting device, the problem that lamp light becomes noise and it is difficult to receive a signal can be solved. In other words, the instrument body is generally made of metal such as an iron plate and may be a shield against the receiving antenna, but part or all of the radio wave receiving antenna may be placed on the outer periphery of the lamp of the instrument body. The reception performance can be ensured by disposing on the reception circuit board disposed in the circuit board. However, in such a conventional lighting device, the antenna cannot be separated greatly from the metal fixture body, and therefore satisfactory reception sensitivity cannot be obtained.

The illuminating device of Patent Literature 1 described above stably receives signals from various directions below the instrument body by installing linear antenna elements in a light irradiation direction perpendicular to the installation direction of the instrument body. be able to.
However, in the illuminating device of Patent Document 1, the antenna element protrudes in a rod shape in the globe, so that the light from the lamp is interrupted and becomes a shadow, or the antenna element protruding when the lamp is replaced becomes an obstacle. There is a risk of damaging the element.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an illumination device that can improve the reception sensitivity of a radio remote controller without providing a protruding antenna structure. .

  The lighting device according to the present invention includes an appliance main body directly attached to a ceiling construction surface, a lamp attached to the appliance main body, a non-metallic glove attached to a receiver provided on the appliance main body so as to cover the lamp, and a receiver. A radio wave receiving antenna that is attached to the device and receives a radio remote control signal.

  The lighting device according to the present invention includes a fixture main body directly attached to a ceiling construction surface, a lamp attached to the fixture main body, a globe covering the lamp and attached to the fixture main body, and a radio remote control signal attached to the glove. And a radio wave receiving antenna.

  According to the illumination device of the present invention, it is possible to improve the receiving sensitivity of the radio remote controller without providing a protruding antenna structure.

  Hereinafter, lighting devices according to a plurality of embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
The lighting device 10 according to the first embodiment of the present invention includes an instrument main body 11, an annular lamp 12 attached to the instrument main body 11, and a plurality of receivers 14 provided on the instrument main body 11 so as to cover the lamp 12. A fixture body 11 is directly attached to the ceiling construction surface 1, including a glove 13 attached to the receiver 14, a radio wave receiving antenna 15 provided on the receiver 14 for receiving a radio remote control signal, and a receiving circuit 16.

  As shown in FIGS. 1 and 2, the instrument body 11 is formed in a disc shape using a thin steel plate material. A holder hole 17 for mounting the attachment holder 18 is formed at the center of the instrument body 11. The attachment holder 18 is electrically connected to an external circuit on the ceiling construction surface 1 side by being hooked on a hook metal fitting (not shown) on the ceiling construction surface 1. Then, by fitting the holder hole 17 of the instrument body 11 to the attachment holder 18, the instrument body 11 is supported by the attachment holder 18 and an external circuit on the ceiling construction surface 1 side is attached to the lower surface of the instrument body 11. It is electrically connected to a lighting circuit (not shown). A plurality of lamp support springs 19 for attaching the lamp 12 are provided on the lower surface of the appliance body 11. The receiver 14 is formed in an L shape in a vertical sectional view, and is arranged in the circumferential direction at the outer edge portion on the lower surface of the instrument body 11.

  The globe 13 is formed in a substantially hemispherical shape by a milky white resin plate member, for example, and has a cylindrical instrument body mounting portion 20 in an upper open portion. The globe 13 has a plurality of substantially triangular prism-shaped protrusions 21 at equal intervals in the circumferential direction on the inner peripheral surface of the instrument body mounting portion 20. After the glove 13 is inserted from the lower side of the instrument body 11 into the outer periphery of the receptacle 14 of the instrument body 11, the projection 21 is received by being rotated at a predetermined angle. It is fitted to the tool 14 and attached to the tool body 11.

  As shown in FIGS. 3 and 4, the radio wave receiving antenna 15 is attached along one rising portion 22 of the plurality of receivers 14 in the instrument body 11. The radio wave receiving antenna 15 is electrically connected through a power feeding unit 23 to a receiving circuit 16 attached to the inner peripheral portion of the receiver 14 of the instrument body 11. Since the radio wave receiving antenna 15 is attached along the rising portion 22 of the receiver 14, the radio wave receiving antenna 15 is disposed away from the metal instrument body 11. The radio wave receiving antenna 15 has a horizontal extending portion 24 that extends in the horizontal direction after rising from the rising portion 22 of the receiver 14. Thereby, since a horizontal receiving portion is formed in the radio wave receiving antenna 15, the directivity with respect to the floor surface can be improved.

  Since the radio wave receiving antenna 15 applies weak radio waves, the transmission energy is very small and energy saving is achieved compared to the infrared remote controller. In addition, since radio waves fly omnidirectionally, operation is possible from anywhere as long as the receiving unit is nearby. Furthermore, since radio waves have a high ability to penetrate objects, operations can be reliably performed even if there are shielding objects or the like.

  Since the radio wave receiving antenna 15 is disposed on the receiver 14 disposed on the outer edge of the instrument body 11 and is disposed so as to rise from the instrument body 11, the reception sensitivity can be increased. In addition, since the radio wave receiving antenna 15 is integrally attached to the receiver 14 along the receiver 14, the antenna length and shape can be designed relatively freely.

Therefore, in the illuminating device 10 of the first embodiment, the radio wave receiving antenna 15 is attached to the receptacle 14 on the outer edge of the instrument body 11.
Thereby, in the illuminating device 10 according to the first embodiment, the radio wave receiving antenna 15 attached to the receiver 14 can increase the radio signal reception sensitivity and does not block the light of the lamp 12. There is no hindrance when replacing the lamp.

(Second Embodiment)
Next, the illuminating device of 2nd Embodiment of this invention is demonstrated. Note that, in the following second embodiment, the same or equivalent components in the drawing are simplified or described for the same components or functionally similar components as those in the first embodiment described above. Omitted.

  As shown in FIGS. 5 and 6, in the illumination device 30 according to the second embodiment of the present invention, the radio wave receiving antenna 31 is attached to the inner peripheral surface of the globe 13 including the appliance main body attaching portion 20. The radio wave receiving antenna 31 is disposed along the inner peripheral surface of the globe 13 by printing or affixing a thin conductor on the inner peripheral portion of the globe 13, and is disposed away from the metal instrument body 11.

  As shown in FIGS. 7 and 8, the radio wave receiving antenna 31 protrudes when the instrument body mounting portion 20 of the globe 13 is rotated after being inserted into the outer peripheral portion of the receiver 14 of the instrument body 11. At a position where the portion 21 is fitted to the receiving tool 14, the power supply portion 23 from the instrument main body 11 is electrically contacted through, for example, a terminal. Therefore, the radio wave receiving antenna 31 can be formed integrally with the globe 13. Since the globe 13 has a smooth hemispherical shape, the antenna length and shape can be designed freely, so that the receiving sensitivity can be improved.

Therefore, in the illumination device 30 of the second embodiment, the radio wave receiving antenna 31 is attached to the globe 13.
Thereby, in the illuminating device 30 of this 2nd Embodiment, the receiving sensitivity of a radio wave signal can be raised with the radio wave receiving antenna 31 attached to the globe 13.

  In addition, the instrument main body 11, the lamp | ramp 12, the glove | globe 13, etc. which were used by each embodiment are not limited to what was illustrated, and can be changed suitably.
