Compact LED package with reduced field angle

1 . A light emitting diode system comprising:

a housing including a light emission opening;

an light emitting diode disposed within the housing;

a first film layer disposed across at least a portion of the light emission opening, the first film layer including uniaxial collimating film configured to direct light from the light emitting diode

2 . The system of claim 1 , wherein the first film layer is configured to direct light from the light emitting diode along a first axis and further comprising:

a second film layer disposed on the first film layer, the second film layer including uniaxial collimating film configured to direct light from the light emitting diode along a second axis offset from the first axis.

3 . The system of claim 1 wherein the housing includes a sloped reflector.

4 . The system of claim 3 wherein the sloped reflector includes a bottom and a top, and wherein the radius of the bottom of the sloped reflector is smaller than the radius of the top of the sloped reflector.

5 . The system of claim 3 wherein the sloped reflector comprises a mirror.

6 . The system of claim 1 wherein the light emitting diode is disposed upon a mirror-finish layer attached to the housing.

7 . The system of claim 6 wherein the mirror-finish layer includes a grooved surface configured to direct incoming light toward the first and second film layers.

8 . The system of claim 1 wherein the uniaxial collimating film comprises a grooved surface.

9 . The system of claim 1 wherein the uniaxial collimating film is configured to concentrate approximately 40 to approximately 70 percent of light generated by the light emitting diode to a center.

10 . The system of claim 1 wherein the uniaxial collimating film resists deforming on exposure to environmental factors.

11 . The system of claim 1 further comprising at least one of a liner and a light guide to diffuse light rays.

12 . A method of collimating light, the method comprising:

receiving light in a first collimating layer;

directing a first portion of the received light through a second collimating layer along a first axis; and

directing a second portion of light through the second collimating layer along a second axis offset from the first axis.

13 . The method of claim 12 wherein the light is generated by a light emitting diode package, and wherein the first portion of the received light is directed through the second collimating layer along a first axis, and wherein the second portion of light is directed through the second collimating layer along a second axis offset from the first axis.

14 . The method of claim 12 further comprising directing a third portion of received light toward a reflective surface of the housing.

15 . The method of claim 12 further comprising reflecting light from a mirror-surface layer toward the first and second collimating layers.

16 . The method of claim 12 further comprising diffusing the directed light with at least one of a liner and a light guide.

17 . The method of claim 12 wherein receiving light in a first collimating layer comprises generating light, and wherein directing a first portion of the received light comprises transmitting the received light when the received light has a predetermined angle, and wherein directing the second portion of the received light comprises reflecting the received light when the received light does not have the predetermined angle.

18 . A system for collimating light, the system comprising:

means for receiving light in a first collimating layer;

means for directing a first portion of the received light through a second collimating layer along a first axis; and

means for directing a second portion of light through the second collimating layer along a second axis offset from the first axis.

19 . The system of claim 18 further comprising means for diffusing light.

20 . The system of claim 18 wherein means for directing a first portion of the received light through a second collimating layer comprises means for directing a first portion of the received light through a second collimating layer along a first axis and wherein means for directing a second portion of light through the second collimating layer comprises means for directing a second portion of light through the second collimating layer along a second axis offset from the first axis.
