SYSTEM AND METHOD FOR LOW LEVEL DIMMING
First Claim
1. A method for manipulating levels of brightness for a lighting device, the method comprising:
- (a) receiving, by an interface device, an input signal being transmitted to a lighting device, the input signal representing a first level of brightness;
(b) identifying, by the interface device, a digital value for the input signal, digital value having a predetermined number of bits;
(c) generating, by the interface device, a truncated digital value by removing a portion of bits from the digital value;
(d) mapping, by the interface device, the truncated digital value to a non-truncated digital value having the predetermined number of bits and that represents a second level of brightness; and
(e) transmitting, by the interface device, a second signal representing the non-truncated digital value as the input signal to be transmitted to the lighting device.

Abstract
The present disclosure is directed to an inexpensive yet intelligent solution for dimming light devices to low level intensities in which the common lighting systems generally have difficulties maintaining stability and flicker-free operation. The systems and method described herein enable a lighting system to utilize a dimmer to dim one or more lighting devices to low level intensities without introducing flickering or inconsistent operation of the lights. More specifically, the systems and methods described herein enable a dimmer to dim lights to anywhere between 0% and 5% of maximum brightness, while ensuring that the lights operate at these levels consistently, smoothly and without any visible flickering.

11. A system for manipulating levels of brightness for a lighting device, the system comprising:
-
an interface device receiving an input signal being transmitted to a lighting device and identifies a digital value for the input signal, the input signal representing a first level of brightness, the digital value having a predetermined number of bits; a truncator of the interface device generating a truncated digital value by removing a portion of bits from the digital value and mapping the truncated digital value to a non-truncated digital value having the predetermined number of bits and that represents a second level of brightness; and wherein the interface device transmits, a second signal representing the non-truncated digital value as the input signal to be transmitted to the lighting device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
