Abstract
An elongated light circuit includes an elongated circuit trace and a plurality of micro-sized, unpackaged LEDs disposed sequentially on the circuit trace. A height of the LEDs ranges from about 12.5 microns to about 200 microns. The elongated circuit trace and the LEDs are coated with a protective coating.
Claims20
A light string including at least a pair of conductive wires, and a plurality of micro-sized, unpackaged LEDs electrically connected to the pair of conductive wires, the LEDs being distributed along a length of the pair of conductive wires, and the LEDs being transferred to the pair of conductive wires via a method comprising acts of:
- positioning the pair of conductive wires to be adjacent to a first surface of an LED carrier carrying multiple LEDs of the plurality of LEDs thereon;
- actuating a reciprocating transfer member to thrust against a second surface of the LED carrier at a position corresponding to a location of an initial LED of the plurality of LED on the first surface of the LED carrier, the actuating of the transfer member causing a localized deflection of the LED carrier in a direction of the pair of conductive wires to position the initial LED proximate to the pair of conductive wires;
- transferring the initial LED directly to the pair of conductive wires;
- shifting the LED carrier such that the transfer member aligns with a subsequent location of a subsequent LED of the multiple LEDs on the first surface of the LED carrier;
- and
- repeating the acts of actuating, transferring, and shifting with respect to consecutive subsequent locations and corresponding consecutive subsequent LED at a predetermined transfer rate to effectuate a transfer of the multiple LEDs onto the pair of conductive wires.
A light string, comprising:
- at least two conductive wires positioned no more than about 200 microns apart;
- and
- a plurality of micro-sized, unpackaged LEDs attached to the at least two conductive wires, a height of the LEDs being no greater than about 200 microns.
An elongated light circuit, comprising:
- an elongated circuit trace;
- and
- a plurality of micro-sized, unpackaged LEDs disposed sequentially on the circuit trace, a height of the LEDs ranging from about 12.5 microns to about 200 microns,
- wherein the elongated circuit trace and the LEDs disposed thereon are coated with a protective coating.
