Abstract
In various embodiments, LED-based illumination devices include an inlet region for receiving the LED light that is complementary in shape to the lens of the LED.
Claims18
An illumination device comprising:
- an illumination module comprising at least one light-emitting diode (LED) having a lens;
- disposed in contact with the illumination module, a light guide having (i) an inlet region for receiving light from the at least one LED, (ii) a collimation region for collimating the received light, and (iii) an emission region for emitting the collimated light to an ambient,
- wherein a shape of the inlet region is nonplanar and substantially complementary to a shape of the LED lens, such that substantially all light emitted through the LED lens strikes the inlet region at an angle perpendicular to a surface of the inlet region.
A method of illumination, the method comprising:
- emitting light through a lens of a light-emitting diode (LED);
- coupling substantially all of the light into a light guide through an inlet region having a nonplanar shape complementary to a shape of the LED lens, such that substantially all light emitted through the LED lens strikes the inlet region at an angle perpendicular to a surface of the inlet region;
- collimating at least a portion of the coupled light;
- and
- emitting at least a portion of the collimated light through the light guide into an ambient.
