The control circuit 250 may be carried by the lighting system body 210 or the shelter body 100 (e.g. embedded in a lining). In some implementations, the shelter body 100 is a tent, as illustrated in FIG. 1, and may also include other temporary shelters, gazebos, shades, awnings, and awnings attached to vehicles. The lighting system 200 is embedded or integrated in the shelter body 100 and configured, in some examples, to illuminate the interior 110 of the shelter body 100. In additional examples, the lighting system 200 is configured to illuminate an area exterior of the shelter body 100. The light emitted by the lighting system 200 may be red, white or any other color. Examples of light emitters 220 include light emitting diodes, illuminable gels, and electroluminescent wire. In some examples, the light emitters 220 include optical fibers. This lighting system 200 can be installed in the shelter body 100 either at the time of manufacture or as an after market system.
The lighting system 200 is controllable at the light system body 210, 30 (e.g. via a switch, dial, or motion detector) and/or by a remote controller 260. The remote controller 260 can be located anywhere around or in the shelter body 100 (e.g. on a shelter wall 102, as shown, or floor 104, proximate to the entry 101, or proximate to the lighting system 200) or hanging from a tether. The remote controller 260 may be in wireless communication with the control circuit 250 (e.g. infrared or radio frequency) to control at least one light emitter 220. For example, when the portable shelter 2 includes multiple lighting systems 200, the remote controller 260 may control each light emitter 220 of each lighting systems 200. Each lighting systems 200 may include a switch to control each light emitter 220 or over-ride the remote controller 260. In some instances, the remote controller 260 is at least partially embedded in the shelter body 100 for aesthetics or robust attachment.
