Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a remote control illuminator.

[0002]

[Prior Art]

 As a remote control illuminator, for example, as disclosed in Japanese Patent Laid-Open No. 63-144729, a ceiling direct-mounting illuminator that is directly attached to the ceiling surface has a remote controller on one side of the illuminator. Is provided, and the lamp is turned on, dimmed, turned off, etc. based on the optical signal from the remote controller received by the light receiving section.

[0003]

[Problems to be solved by the device]

 By the way, even if the remote control optical signal is transmitted from the other side of the appliance, that is, the side opposite to the light receiving section, the remote control optical signal cannot be reliably received by the light receiving section because the light receiving section becomes a shadow of the appliance. Therefore, it is necessary to change the transmission position and operate the remote control, or to reflect the remote control optical signal on the wall surface and transmit it to the light receiving unit.

However, if the remote control operation is performed while changing the transmission position, the characteristics of the remote control-operated illuminator are lost.

Further, when the remote control optical signal is reflected on a wall surface, etc., the remote control must be operated in a direction different from that of the equipment, and moreover, the state of the room such as a curtain on the wall surface. In some cases, the remote control optical signal is not reliably reflected toward the light receiving part.

The present invention has been made in view of such a point, and can reliably receive a remote control optical signal transmitted from the direction of the other side of the device opposite to the light receiving part provided on the one side of the device. The purpose of the present invention is to provide a lighting fixture that can eliminate the directionality of the remote control transmission position with respect to the receiving unit.

[0007]

[Means for Solving the Problems]

 The present invention relates to a lighting device having a light receiving section on one side of a fixture and controlling the lighting state of a lamp based on a remote control optical signal received by the light receiving section. Is a reflector that reflects a remote control optical signal from the opposite side of the device toward the light receiving part.

[0008]

[Action]

 According to the present invention, even when the remote controller is operated from the direction of the other side of the device opposite to the light receiving part facing the one side of the device, the remote controller optical signal strikes the reflector and is reflected by this reflector to be received by the light receiver.

[0009]

【Example】

 The configuration of one embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a cross-section one side of a ceiling-mounted light fixture (the other side has a substantially symmetrical structure with the one side, but a light receiving section and a reflector described later are only on one side), and 1 is The instrument body is formed in a substantially circular shape, and an attachment metal fitting 4 detachably attached to a hook ceiling 3 installed on a ceiling surface 2 is provided in a central portion.

A plurality of annular lamps 5 are supported by a lamp holder 6 on the lower surface of the instrument body 1, and a substantially hemispherical light-transmitting shade 7 that opens upward is detachably attached. ing.

On the upper surface of the fixture body 1, a lighting device 8 including an inverter or the like for driving the lamp 5 to be driven, and an operation of the lighting device 8 based on a remote control optical signal received by a light receiving unit 11 described later are provided. A control unit (not shown) for controlling is provided.

A light receiving unit 11 for receiving a remote control optical signal such as infrared rays is installed on one side of the instrument body 1. The light receiving portion 11 is supported by the support member 12 with the light receiving surface 11a facing outward from the upper portion of the outer edge of the shade 7. The base of the support member 12 is fixed to the rising wall 1a provided on the peripheral edge of the instrument body 1 with a screw 13.

On one side of the instrument main body 1, a reflector for reflecting the remote control optical signal from the direction of the other side of the instrument opposite to the light receiving unit 11 toward the light receiving unit 11 corresponding to the front of the light receiving unit 11. 15 is attached. As shown in FIG. 2, the reflector 15 is fixed to the attachment piece 1b of the instrument body 1 with the screw 18 through the attachment hole 17 formed in the base 16, and is bent downward in an arc shape at the tip. A reflecting surface 19 is formed which is bent and also bent in an arc shape in the horizontal direction along the circumference of the instrument.

Next, the operation of this embodiment will be described.

When a remote control transmitter (not shown) is operated from one side of the instrument, the remote control optical signal S 1 emitted from the transmitter is directly received by the light receiving unit 11.

When the remote controller is operated from the other side of the instrument, the remote control optical signal S2 emitted from the transmitter strikes the reflecting surface 19 of the reflector 15 and is reflected by the reflecting surface 19 to be received by the light receiving unit 11. To be done.

Then, the control unit controls the operating state of the lighting device 8 based on the signal received by the light receiving unit 11, and causes the lamp 5 to be turned on, dimmed, and turned off.

Therefore, the remote control optical signal transmitted from the direction of the other side of the device opposite to the light receiving part 11 provided on the one side of the device can be surely received, and the remote control transmission position for the light receiving part 11 can be detected. The directionality of can be eliminated.

Next, FIGS. 3 and 4 show another embodiment. In this embodiment, a frame body 21 is provided as the reflector 15, and the frame body 21 has an annular reflecting portion 23 projectingly formed on the lower surface of a disk-shaped base portion 22 attached to the ceiling surface 2. A lamp 24 having a built-in lamp or the like is attached to the center of the lower surface of the lamp 24, and the entire outer circumference of the lamp 24 is surrounded by the reflecting portion 23. A decorative portion 25 that is uneven in the circumferential direction is formed on the inner and outer surfaces of the reflecting portion 23, and the inner surface is formed as a reflecting surface 26 that reflects the remote control optical signal toward the light receiving portion 11.

When the remote control transmitter 31 operates the remote controller from the other side opposite to the light receiving section 11 provided on one side of the instrument, the remote control signal S 3 emitted from the transmitter 31 is reflected by the frame 21. The light impinges on the reflecting surface 26 of the portion 23, is reflected by the reflecting surface 26, and is received by the light receiving portion 11.

Therefore, also in this embodiment, the same operational effects as the above-mentioned embodiment are exhibited. Moreover, in this embodiment, since the reflecting portion 23 of the frame body 21 is configured so as to surround the entire outer periphery of the lamp 24, the frame body 21 has an effect as a decorative body, and as a reflector in terms of design. Can be excluded.

[Effect of the device]

 According to the present invention, a reflector for reflecting a remote control optical signal from the direction of the other side of the device opposite to the light receiving part toward the light receiving part is provided in front of the light receiving part provided on the one side of the device. The remote control optical signal transmitted from the direction of the other side of the device, which is the opposite of the remote control unit, can be reliably received by the light receiving unit, and the directivity of the remote control transmission position with respect to the receiving unit can be eliminated.
