Problems solved by technology

[0002] The technology of applying light-emitting devices to the communication field has been studied for a period of time, but the promotion and application of this technology are restricted by the frequency of ordinary LED devices, and the corresponding driving and control circuit technology is far from mature and has not formed an international standard. , still in its infancy
The principle of light-emitting diode visible light communication technology is to use phosphor powder and blue light chips to form white LEDs for lighting and communication. The current white LEDs have insufficient electron-hole recombination rate, narrow frequency band, and insufficient light-emitting area. Large, which limits its application in the field of communication

Embodiment

[0018] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a lighting and communication light-emitting diode device sequentially includes a positive electrode 2, a plurality of ring-shaped chip chips 5 arranged in a matrix and a negative electrode 3, and the ring-shaped chip chips 5 sequentially include a transparent electrode layer 8, an empty space A hole generating p-type layer 9 , an electron-hole recombination layer 10 , an electron generating n-type layer 11 and a substrate 12 .

[0019] During operation, the electron-generating n-type layer 11 provides electrons, the hole-generating p-type layer 9 provides charges, and the electrons and holes recombine in the electron-hole recombination layer 10 and emit light. In this embodiment, the ring-shaped chip core particles are used to make electron-hole recombination evenly and achieve a high recombination rate, thereby achieving the technical effect of high speed and wide frequency band of the device.

Abstract

The invention discloses a light-emitting diode device for lighting and communication, which sequentially includes a positive electrode, a plurality of ring-structure chip core particles arranged in a matrix and a negative electrode, and the ring-structure chip core particles sequentially include a transparent electrode layer and a hole-generating p-type layer , electron-hole recombination layer, electron-generating n-type layer and substrate. The invention adopts the ring-shaped structure chip core particles to make electron-hole recombination uniform and achieve high recombination rate, thus achieving the technical effects of high speed and wide frequency band of the device.

Description

technical field [0001] The invention relates to the technical field of photoelectric devices, in particular to a light-emitting diode device for lighting and communication. Background technique [0002] The technology of applying light-emitting devices to the communication field has been studied for a period of time, but the promotion and application of this technology are restricted by the frequency of ordinary LED devices, and the corresponding driving and control circuit technology is far from mature and has not formed an international standard. , is still in its infancy. The principle of light-emitting diode visible light communication technology is to use phosphor powder and blue light chips to form white LEDs for lighting and communication. The current white LEDs have insufficient electron-hole recombination rate, narrow frequency band, and insufficient light-emitting area. large, which limits its application in the communication field.
