Modular coordinated lighting system
摘要
說明書
The auto shutoff timer for each wireless lighting device may be updated or reset upon receiving the control signal so that all wireless lighting devices in the same group may be maintained in an on state as long as motion is detected by any one light in the group. Eventually, when there is no longer motion detected in the area, the auto shutoff timer of the wireless lighting device that lastly detects motion may expire, and that wireless lighting device may send a shutoff control signal to turn off the light source in all devices in the group. In some embodiments, each of the wireless lighting devices receiving the shutoff control may turn off its light source immediately. In other embodiments, each of the wireless lighting devices receiving the shutoff control may reset or update the shutoff timer upon receiving the shutoff control, and turn off the light source when the shutoff timer expires. In doing so, the light sources of the lighting devices belonging to the same group may be turned off in a coordinated manner, for example, at substantially the same time. The auto shutoff timer may define a listen period for the wireless lighting device to listen to commands from other devices or detect motion signals before it turns off the lighting source.
