Flexible LED Lighting Element
First Claim
Patent Images
1. A flexible lighting element, comprising:
- a flexible channel having a bottom and side walls;
a plurality of spaced apart light emitting diode modules disposed on the bottom of the elongate channel, each of the plurality of spaced-apart light emitting diode modules each includinga flexible printed circuit board,a housing coupled to the flexible printed circuit board and having a cavity, anda light emitting diode mounted in the cavity,a first encapsulant surrounding the light emitting diode and filling the cavity and a first group of embedded phosphor particles; and
a second encapsulant surrounding the plurality of spaced-apart light emitting diode modules and filling the channel to a level sufficient to encapsulate the light emitting diodes.

Abstract
A flexible LED lighting module includes a flexible housing and flexible PCB to which LED units are mounted. An encapsulant fills a channel of the flexible housing and has a same or similar optical refractive index value as is used in the LED unit to hold phosphorous particles used for coloring of the LED. Use of the encapsulant changes the color of the light ultimately emitted from the flexible LED lighting module, and this factor is corrected for in calibration processes associated with the flexible LED lighting module.
