Abstract

A synchronous and/or programmed flare control method for an outdoor light signal group is designed by having coordinated universal time from the global position system and planned control of the light source group to achieve sync-programming flare; power source for each light source being separately connected to allow maximal cable layout flexibility without having to provide signal cable between controller and each light signal.

Claims

1. A control method for synchronous and/or programmed flare of an outdoor or remote light signal group to achieve decentralized control system purpose by having coordinated universal time signals emitted from global position system as a common time-base.

2. A control method for synchronous and/or programmed flare of an outdoor or remote light signal group as claimed in claim 1, wherein, a device for the light signal group is limited to fixed traffic guide marks or provisional warning device provided on edge of a road;

a geographical index showing long range boundary lines in a seaport, waterway or a plateau; and

decoration or advertisement light source to a building or road.

3. A control method for synchronous and/or programmed flare of an outdoor or remote light signal group as claimed in claim 1, wherein, all settings for 3D coordinates for multiple light sources (located with several kilometers from one another) within a region are preset at same value to read time signals from the global position system;

and intermittent receiving signals from only one satellite is sufficient to maintain synchronous precision of individual time-base of each light source.

4. A control method for synchronous and/or programmed flare of an outdoor or remote light signal group as claimed in claim 1, the flare control of light sources is preset in a fully fixed single flare mode;

or in a mode allowing limited adjustment by means of a switch;

or cabled such as RS-232 or radio such as IRDA communication interface and a PC are used to transmit individual flare sequence to its respective controller allowing free adjustment of flare pattern.
