Three dimensional LED device and method of manufacture
Solid-state lighting devices, and more particularly to a three-dimensional (3D) light-emitting diode (LED) device and a method of manufacture are disclosed. A submount of the LED can have several submount portions that are angled with respect to each other, and LED chips can be mounted on each submount portion, such that the LED chips of the device are angled at different angles with respect to each other. In an embodiment, the LED device can include a heatsink that is in contact with each of the submount portions to channel heat away from the LED chips. The LED chips can be mounted on the submount portions when all submount portions are laying flat, and then the submount portions can be pushed or punched into their respective angles.
1. A light-emitting diode (LED) device, comprising:
a submount comprising a plurality of submount portions that have respective surfaces that are angled with respect to each other and with respect to a surface of a remainder of the submount, wherein a first end of each submount portion is flexibly attached to an edge of the submount that forms a boundary around a recess, and wherein a second end of each submount portion, opposite the first end, extends into the recess, and wherein respective second ends are not in contact with each other; and
an LED chip that is mounted on each of the respective surfaces of the plurality of submount portions.
2. The LED device of claim 1 , wherein the plurality of submount portions comprise electrical traces upon which the plurality LED chips are mounted.
3. The LED device of claim 1 , further comprising a heat sink in contact with each of the plurality of submount portions.
4. The LED device of claim 3 , further comprising an LED chip mounted on a top surface of the heat sink with a normal that is parallel to the surface of the remainder of the submount.
5. The LED device of claim 1 , further comprising a cover structure covering the plurality of submount portions and LED chips.
6. The LED device of claim 1 , wherein each submount portion of the plurality of submount portions comprise a plurality of LED chips mounted thereon.
7. The LED device of claim 6 , wherein each LED chip of the plurality of LED chips is configured to emit a different color of light.
8. The LED device of claim 1 , wherein the plurality of submount portions are at least one of a triangular or quadrilateral shape.
