Abstract: The light-emitting diode package includes a plurality of bumps being a couple corresponding to each other. Each of the bumps has a first part and a second part placed under the first part, and a gap is formed between the bumps in a period-repeating wriggle shape or an irregular wriggle shape. Accordingly, the distance between the bumps of the light-emitting diode package is small, which results in a less stress being concentrated at the space between the bumps, as a result, a crack is difficultly caused by the stress to the light-emitting diode package, in other words, the structural strength between the bumps and the covering part is enhanced. Still, while being manufactured, the yield rate of the light-emitting diode package is also improved since there is almost no crack to reduce the yield rate.
