Abstract

A luminaire includes: a main body having a placement surface on which a light-emitting module is placed to emit light forward; and a wireless communication module which receives, by wireless communication, a control signal for controlling the light-emitting module. The wireless communication module: includes a substrate, and a transceiver which is provided on the substrate and receives the control signal. The wireless communication module is secured to the main body in such an orientation that the transceiver is located forward of the main body and the substrate intersects the placement surface of the main body.

First claim

What is claimed is:

1. A luminaire comprising:
a main body having a placement surface on which a light emitter is placed to emit light forward; and
a wireless communication unit which receives, by wireless communication, a control signal for controlling the light emitter, wherein
the wireless communication unit
(i) includes:
a substrate; and
a receiver which is provided on the substrate and receives the control signal, and

(ii) is secured to the main body in such an orientation that the receiver is located forward of the main body and the substrate intersects the placement surface of the main body,
the main body has a through hole penetrating the placement surface, and
the wireless communication unit is inserted in the through hole.

2. The luminaire according to claim 1 , wherein
the substrate is elongated,
the receiver is provided at a position closer to one end of the substrate in a lengthwise direction of the substrate,
the wireless communication unit further includes a controller which (i) is provided at a position closer to the other end of the substrate in the lengthwise direction and (ii) processes the control signal received by the receiver, and
the placement surface is located between the receiver and at least a portion of the controller in the lengthwise direction.

3. The luminaire according to claim 2 , further comprising:
a power supply unit which is disposed on a reverse side of the placement surface, and supplies power for turning ON the light emitter, wherein
the power supply unit includes a circuit board, and
the wireless communication unit is connected to the circuit board via a connector.

4. The luminaire according to claim 1 , wherein
in a front view of the placement surface:
the light emitter is ring-shaped; and
the wireless communication unit is located inward of the light emitter that is ring-shaped.

5. The luminaire according to claim 4 , wherein
the substrate is orthogonal to the placement surface, and
the substrate has major surfaces lying along a radial direction of the light emitter that is ring-shaped.
