The angled connector has a plurality of terminal pairs arranged such that when two LED light strips are connected, a distance between an end LED on one strip and an end LED on the other strip is approximately the same as a distance between adjacent equally-spaced LEDs on surfaces of the two strips. Used in a lighting fixture, a non-linear light source is retained within a housing having an opening through which light from LEDs can be directed. At least first and second adjacent LED light strips are connected at an angle to one another and a distance between end LEDs is approximately the same as a distance between equally-spaced LEDs on the surface of both the first and second LED strips. This configuration eliminates dark gaps at the corners of the fixture.
