Optical Cup For Lighting Module
A lighting module comprising a base panel and a plurality of light-emitting diode (LED) chips attached directly to the base panel. The LED chips are in electrical communication with conductive traces on the base panel, which deliver a current to the LED chips. Various embodiments of this generally described lighting module are also presented. Additionally, methods of preparing such a lighting module, and system components of the lighting module are presented.
1 . An optical cup for use in a lighting module, comprising:
a lower surface;
a peripheral wall extending upward from the lower surface;
a lip region formed along the peripheral wall; and
an angled inner surface extending from the lip region to the lower surface so as to form a central opening in the optical cup.
2 . The optical cup of claim 1 , further comprising a reflective coating on the angled inner surface.
3 . The optical cup of claim 1 , further comprising at least one cut-out region in the peripheral wall.
4 . The optical cup of claim 1 , further comprising three cut-out regions in the peripheral wall.
5 . The optical cup of claim 1 , further comprising means for eliminating bubbles from forming on the lower surface of the optical cup when the optical cup is attached to a substrate.
6 . The optical cup of claim 1 , further comprising an optical disk disposed within the optical cup adjacent to the lip region.
7 . The optical cup of claim 1 , further comprising means for converting light emitted from a light-emitting diode chip to white light.
8 . The optical cup of claim 1 , further comprising means for affecting the light emitted from a light-emitting diode chip.
9 . The optical cup of claim 1 , wherein the central opening of the optical cup has a diameter of about 1.0 mm
10 . The optical cup of claim 1 , wherein a height of the optical cup is about 1.7 mm.
11 . A lighting module, comprising:
a base panel;
a light-emitting diode chip attached directly to the base panel and in electrical communication with a conductive trace on the base panel, wherein the light-emitting diode emits light;
an optical cup surrounding the light-emitting diode chip; and
means for effecting the light emitted from the light-emitting diode chip.
