Color-changing lighting dynamic control
A computerized communications system for remotely controlling various color-changing lighting scenes on color-changing lighting fixtures at a premises. The color-changing lighting systems at the remote premises are used to communicate emergency information such as the existence and type of an emergency.
1. A method of communicating emergencies using color-changing light sources, by emitting color-coded lighting messages, the method comprising:
emitting from the at least one color-changing light source a first message segment consisting of three segment elements of lights-on of a first selected color alternated with three message elements of lights-off, wherein the color of the first selected color indicates an emergency type; and then
emitting from the at least one color-changing light source a second message segment consisting of three segment elements of lights-on of a white color alternated with three message elements of lights-off; and then
emitting from the at least one color-changing light source a third message segment identical to the first message segment; and then
repeatedly and sequentially emitting the first, second and third message segments; and then
changing at least one of the message segments, indicating verification of the emergency type.
2. The method of claim 1 , wherein for the second message segment each of the lights-on message elements has a hold time of 0.5 seconds and each of the lights-off message elements has a hold time of 0.05 seconds.
3. The method of claim 1 , further comprising an initial fourth message segment alternatingly emitted between repetitions of the first coded emergency message.
4. The method of claim 1 , wherein the initial fourth message segment comprises alternating emissions of white light and no light, the fourth message segment indicating that the emergency type at the premises is unverified.
5. The method of claim 4 , wherein the changed fourth message segment comprises a single emission of white light.
6. The method of claim 1 , wherein the duration of the hold times for each lights-on message element is 0.2 seconds and the duration of the hold times for each lights-off message element is 0.05 seconds.
7. The method of claim 1 , further comprising changing a message segment by adding a fade effect to at least one lights-on segment element, the change indicating verification of the emergency type.
8. The method of claim 1 , further comprising changing the first message segment to consist of three segment elements of lights-on of a first selected color alternated with three message elements of lights-on of a white color, the change indicating verification of the emergency type.
