Lighting apparatus
View Patent ↗A lighting apparatus includes: a light source unit including a light emitter and a first casing in which the light emitter is housed; a communication unit including a radio receiver which receives a wireless signal for controlling a light emitting state of the light emitter and second casing in which the radio receiver is housed; a first power line including a plug and connected to the communication unit; and a power source which generates power for causing the light emitter to emit light, using power received by the plug.
1. A lighting apparatus, comprising:
a light source housing including a light emitter and a first casing in which the light emitter is housed;
a communication housing including a radio receiver which receives a wireless signal for controlling a light emitting state of the light emitter, and a second casing in which the radio receiver is housed;
a first power line including a plug and being connected to the communication housing; and
a power source which generates power for causing the light emitter to emit light, using power received by the plug,
wherein the light source housing and the communication housing are separate from each other and are separately movable with respect to each other so that mounting positions of the light source housing and the communication housing at an installation location at which the lighting apparatus is installed are separately changeable.
2. The lighting apparatus according to claim 1 , wherein the power source is housed in the first casing.
3. The lighting apparatus according to claim 1 , further comprising:
a dimmer which is electrically connected to the first power line and controls dimming of the light emitter,
wherein the radio receiver receives, as the wireless signal, a dimming signal for controlling dimming of the light emitter, and outputs the received dimming signal to the dimmer.
4. The lighting apparatus according to claim 3 , wherein the dimmer is housed in the second casing.
5. The lighting apparatus according to claim 1 , further comprising a second power line which connects the light source housing and the communication housing.
6. The lighting apparatus according to claim 5 , further comprising a plurality of the light source housings, and a plurality of the second power lines, and
wherein the plurality of the second power lines are drawn out of the second casing of the communication housing and are connected to the plurality of the light source housings in a one-to-one relationship.
7. The lighting apparatus according to claim 5 , further comprising a plurality of the second power lines, each drawn out of the second casing of the communication housing,
at least one of the plurality of the second power lines that is drawn out of the second casing of the communication housing being connected to the light source housing, and
at least another one of the plurality of the second power lines that is drawn out of the second casing of the communication housing being connected to an electrical device.
8. The lighting apparatus according to claim 7 , wherein the electrical device is a speaker.
9. The lighting apparatus according to claim 1 ,
wherein the lighting apparatus is a first lighting apparatus that communicates with a second lighting apparatus,
wherein the radio receiver of the communication housing of the first lighting apparatus includes a circuit which transmits the received wireless signal to a radio receiver of a communication housing of the second lighting apparatus.
10. The lighting apparatus according to claim 1 , wherein the first casing of the light source housing includes:
a body configured to attach to the light emitter; and
a light-transmissive cover which covers the light emitter.
11. The lighting apparatus according to claim 5 , wherein the second power line is exposed from the second casing of the communication housing.
