Patent number: 9603209Abstract: Dimming or illumination control of an LED-based lighting fixture can utilize a combination of pulse width modulation and constant current reduction. A light emitting diode driver can implement pulse width modulation to control light over a first light intensity range and constant current reduction over a second light intensity range. The first light intensity range can be less intense than the second light intensity range. Thus, the driver can practice constant current reduction for dimming at higher light intensities and pulse width modulation for dimming at lower light intensities.Type: GrantFiled: September 3, 2015Date of Patent: March 21, 2017Assignee: COOPER TECHNOLOGIES COMPANYInventors: Liang Fang, William Lee Shiley, James Moan, James Christopher Andrews
