Abstract
An LED chip for use in an LED chip array forming a continuous array of LEDs. The LED chip comprises an array of LEDs on a substrate. LEDs in a row of the array are longitudinally offset from corresponding LEDs in another row. Adjacent LEDs in each row of the array are separated by a longitudinal pitch. At least part of an end face of the substrate is angled with respect to a transverse axis of the LED chip such that the LED chip is positionable adjacent another LED chip to maintain the longitudinal pitch between adjacent LEDs on different chips.

A light emitting diode (LED) chip comprising:
- a substrate having at least part of a first end face extending at a non-orthogonal angle relative to a longitudinal direction of the substrate;
- and
- an array of LEDs on the substrate arranged in a plurality of rows along the longitudinal direction, adjacent LEDs in a row of the array longitudinally offset by a longitudinal pitch that corresponds to multiples of a diameter of an LED in the row, LEDs in the row longitudinally offset from LEDs in an adjacent row of LEDs.
A method of manufacturing an LED chip comprising:
- forming an array of LEDs on a substrate arranged in a plurality of rows extending along a longitudinal direction of the substrate so that adjacent LEDs in a row of the array are longitudinally offset by a longitudinal pitch that corresponds to multiples of a diameter of an LED in the row and LEDs in the row longitudinally offset from LEDs in an adjacent row of LEDs;
- and
- dicing the substrate formed with the array of LEDs so that at least part of a first end face of the substrate extends at a non-orthogonal angle relative to a longitudinal direction of the substrate.
A light emitting diode (LED) chip fabricated by a process comprising:
- forming an array of LEDs on a substrate arranged in a plurality of rows extending along a longitudinal direction of the substrate so that adjacent LEDs in a row of the array longitudinally are offset by a longitudinal pitch that corresponds to multiples of a diameter of an LED in the row and the LEDs in the row longitudinally offset from LEDs in an adjacent row of LEDs;
- and
- dicing the substrate formed with the array of LEDs so that at least part of a first end face of the substrate extends at a non-orthogonal angle relative to a longitudinal direction of the substrate.
