Embodiment Construction

[0057] Referring now to the accompanying drawings, figure 1 is a block diagram of an embodiment of the present invention for controlling illuminance and for reducing sun glare in a space such as a room where daylight and artificial light act as light sources. System 10 includes a central processing unit 100, which may be a Lutron GRAFIK Central Lighting Processor, eg Model No. GR6MXINP. The central processing unit 100 has a dimming panel 110 connected thereto, and the dimming panel 110 has various lighting loads 120, which can be any type of light source, including but not limited to incandescent, fluorescent, HID, etc. (High Intensity Discharge), Neon, LED (Light Emitting Light Emitting Diode), LV (Low Voltage), and the lighting load can be controlled by the dimming panel 110 in response to commands from the central processing unit 110 via digital link 137 communication . The dimming panel may be a Lutron type GP12-1203-ML-15. The light sensor interface 130 is connected ...

Abstract

An illumination maintenance system for maintaining a desired illumination profile in a space throughout at least a portion of a day where the illumination sources include daylight and artificial light, the system comprising a first sensor for sensing an illumination level in at least a portion of the space, at least one window treatment for at least one opening for allowing daylight into the space, the window treatment selectively altering the amount of daylight entering the space, a plurality of electric lamps providing artificial light to supplement the daylight illumination of the space; the electric lamps being dimmable, a control system controlling the at least one window treatment and the plurality of electric lamps to maintain the desired illumination profile in the space, the control system controlling the plurality of electric lamps so that the dimming level of each lamp is adjusted to achieve the desired lighting profile and compensate for the daylight illumination in the space throughout at least the portion of the day; and the control system further operating to adjust the window treatment in the event of sun glare through the opening to reduce the sun glare and such that when the desired illumination profile within a defined tolerance is achieved, the control system stops varying the dimming levels of the lamps and the adjustment of the at least one window treatment.
