Embodiment Construction

[0018] The present invention discloses a light-emitting diode element structure. In order to make the description of the present invention more detailed and complete, please refer to the following description and cooperate with Figure 3A to Figure 6 icon of the .

[0019] Various embodiments of the present invention are described below with reference to the accompanying drawings. With the market demand, the volume of light emitting diode components is gradually reduced. When the area of ​​each light-emitting diode unit in the light-emitting diode element is correspondingly reduced, the electrodes formed on the light-emitting surface of the light-emitting diode unit, the electrode extension, and the opaque structure such as the conductive wiring structure will greatly affect the light-emitting diode. The light extraction efficiency of the unit.

[0020] first, Figure 3A and Figure 3B Shown are the side view and the top view of the LED array element 2 according to the fir...

Abstract

The invention discloses a light emitting diode element. The light emitting diode element comprises a substrate comprising four edges, a plurality of light emitting diode units formed on the substrate,and a plurality of conductive wiring structures connected to the plurality of the light emitting diode units, wherein the plurality of the light emitting diode units form a series array with at leastthree adjacent light emitting unit rows; and one of the plurality of the light emitting diode units crosses at least two adjacent light emitting unit rows in the light emitting unit rows, and one long side of the light emitting diode unit is adjacent to one edge of the four edges of the substrate.

Description

[0001] This application is a divisional application of the Chinese invention patent application (application number: 201310631968.X, application date: November 29, 2013, invention name: light-emitting diode element). technical field [0002] The invention relates to a light emitting diode element, in particular to an array type light emitting diode element with high light extraction efficiency. Background technique [0003] The light-emitting diode (LED) is different from traditional light sources in its light-emitting principle and structure. It has the advantages of low power consumption, long component life, no need to warm up the lamp, and fast response speed. In addition, it is small in size, shock-resistant, and suitable for mass production. It is easy to make extremely small or arrayed components according to application requirements, and is widely used in the market. For example, optical display devices, laser diodes, traffic signs, data storage devices, communicatio...
