Abstract

Disclosed is a lighting system simulating sunrise and sunset, which can control a desired luminous intensity and color temperature to be turned on or off on a wanted time in an easier manner by employing a remote controller for transferring a remote signal, a controller for controlling the on and off condition of the luminous intensity and color temperature of a stabilizer based on the remote signal transferred from the remote controller and a self stacked signal, and a liquid crystal display device for displaying the luminous intensity and the color temperature on a graphic screen to easily identify the result of the aforementioned control.

Claims

1. A lighting system simulating sunrise and sunset, comprising:

a remote controller for transmitting a remote signal;

a mi-com main controller for controlling an input signal thereof and said remote signal of said remote controller;

a graphic liquid crystal display (LCD) device for graphically displaying a luminous intensity and a color temperature controlled by said mi-com main controller;

a power supplier including a relay for supplying a D.C. power to said mi-com main controller and turning on or off an A.C. power supply under the control of said mi-com main controller;

a plurality of illuminators for illuminating at said luminous intensity and color temperature controlled by said remote signal of the remote controller and said input signal of said mi-com main controller;

an auxiliary remote controller for transmitting a remote signal;

a mi-com auxiliary controller for controlling an input signal thereof and said remote signal of said auxiliary remote controller;

an auxiliary graphic LCD device for graphically displaying a luminous intensity and a color temperature controlled by said mi-com auxiliary controller;

an auxiliary power supplier including a relay for supplying a D.C. power to said mi-com auxiliary controller and turning on or off an A.C. power supply under the control of said mi-com auxiliary controller; and

a plurality of auxiliary illuminators for illuminating at said luminous intensity and color temperature controlled by said remote signal of said auxiliary remote controller and said input signal of said mi-com auxiliary controller.

2. The lighting system of claim 1, wherein said mi-com main controller is able to easily control data throughout 24 hours by setting required data on a necessary point of time at specific intervals, and confirm overall 24-hour reservations at one sight by using said graphic LCD device.

3. The lighting system of claim 1, wherein said auxiliary illuminators connected to said mi-com auxiliary controller which is connected to said mi-com main controller in RS232C communication manner are controlled to be turned on or off at said specific luminous intensity and color temperature, and interlocked to the operation of said main controller so as to be simultaneously turned on or off.

4. The lighting system of claim 1, wherein if a user sets a reserved time and a sunrise period, said mi-com main controller controls said lighting system turned on at minimum luminous intensity and color temperature values before said pre-set time, said luminous intensity and color temperature values increasing by specific steps for said pre-set period and corresponding to the luminous intensity and color temperature of the sunrise time at the end of said pre-set period, later keeping final values.

5. The lighting system of claim 1, wherein if said user sets a reserved time and a sunset period, said mi-com main controller controls said lighting system turned on before said pre-set time, said luminous intensity and color temperature values decreasing by specific steps for said pre-set period and the power supply to said lighting system turned off at the end of said pre-set period, later keeping final values.

6. The lighting system of claim 1, wherein said mi-com main controller controls said lighting system to illuminate at said pre-set luminous intensity and color temperature, which may be re-set at said user'"'"'s request.

7. The lighting system of claim 1, wherein if said user inputs a function key for producing a sunset effect in a one-touch manner, said mi-com main controller controls current luminous intensity and color temperature turned into initial luminous intensity and color temperature values in several seconds, said initial luminous intensity and color-temperature values decreasing by specific steps for a predetermined period of time and then keeping said final values when said power supply to said lighting system is turned off at the end of said pre-set period,

8. The lighting system of claim 1, wherein said mi-com main controller can lock said on-off action of said power supply, and said luminous intensity and color temperature by selecting either said main controller or said auxiliary controller connected to said main controller, and cancel said lock condition by letting said auxiliary controller request said main controller for said lock cancellation by inputting a specific key on said auxiliary controller, which is capable of self-setting later.

9. The lighting system of claim 1, wherein said mi-com main controller displays a variable range of said luminous intensity and color temperature and also the current state within a pre-displayed range when said user inputs a pertinent operation key disposed in said remote controller or in said mi-com main controller on said graphic LCD device, to set an illumination state desired by said user in a faster way.

10. The lighting system of claim 1, wherein said mi-com main controller pre-heats filaments of said illuminators by applying voltage to the filaments before said power-on of said illuminators to allow said illumination to be smoothly variable at a low luminous intensity when said user sets said reserved time and sunset period.

11. The lighting system of claim 1, wherein said mi-com main controller controls said luminous intensity and color temperature values to go up and down at a specific cycle repeatedly but to perform a sort of wave function where said values have a pause at the lowest point and at the highest point for several seconds.
