Patent number: 11566759Abstract: A lighting system includes an LED downlight mountable to a ceiling, a driver, and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The driver has an input with a first voltage and an output with a second voltage, the second voltage being lower than the first and being provided through a wire system extending from the LED driver. The IDC connects the downlight to the wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding IDC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.Type: GrantFiled: August 2, 2021Date of Patent: January 31, 2023Assignee: Lynk Labs, Inc.Inventor: Michael Miskin
