Light-emitting diode device

A light-emitting diode device, comprising:

• a substrate, comprising a first surface;
• a plurality of light-emitting units formed on the first surface, wherein the light-emitting units form a serially-connected array, and the array comprises n adjacent light-emitting unit rows, wherein n≧5, and the light-emitting units in the same rows connect vertically and/or the light-emitting units in the same columns connect horizontally, and a connecting direction of at least three light-emitting units in two adjacent rows are the same;
• a plurality of conductive connecting structures connecting the plurality of light-emitting units;
• a first contact light-emitting unit formed on the first surface and in the first light-emitting unit row, and a first electrode pad formed on the first contact light-emitting unit;
• and
• a second contact light-emitting unit formed on the first surface and in the nth light-emitting unit row, and a second electrode pad formed on the second contact light-emitting unit;
• wherein at least three light-emitting units in the first light-emitting unit row have a first area, and at least three light-emitting units in the nth light-emitting unit row have a second area, wherein the first area and the second area are not equal.

A light-emitting diode device, comprising:

• a substrate, comprising a first surface;
• a plurality of light-emitting units comprising four edges respectively, formed on the first surface, wherein the light-emitting units form a serially-connected array, and the array comprises at least three adjacent rows;
• and
• a plurality of conductive connecting structures connecting the plurality of light-emitting units, wherein the two conductive connecting structures of one light-emitting unit are formed on the same edge of the light-emitting unit, and the light-emitting unit which has two conductive connecting structures formed on the same edge crosses two adjacent rows.
