Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] see figure 1 , figure 1 It is a schematic cross-sectional structure diagram of an embodiment of the light-emitting device of the present invention. The light emitting device 100 includes quantum dots 10 and a transparent encapsulation device 20 .

[0029] The quantum dots 10 are encapsulated in the transparent encapsulation device 20 . The quantum dot is a kind of nano particle composed of II-VI group or III-V group elements. The particle size of quantum dots is generally less than or equal to 10nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure with molecular characteristics, and can emit fluorescence after being excited.

[0030] The transparent packaging device 20 includes a light-incident surface 22 and a light-exit surface 24 , and the surface of the light-...

Abstract

The invention provides a light emitting device. The light emitting device comprises a transparent encapsulating device and a quantum dot. The transparent encapsulating device comprises a light entering face and a light emitting face. The surface of the light entering face is provided with uneven micro-structures. The quantum dot is encapsulated in the transparent encapsulating device. When laser light irradiates the quantum dot from the light entering face, the quantum dot is triggered to shine, and the light produced by the quantum dot will be emitted out from the light emitting face. In this way, different requirements of different light sources can be satisfied.

Description

technical field [0001] The invention relates to the technical field of light emitting sources, in particular to a light emitting device. Background technique [0002] Since the quantum dots can be irradiated by an external light source such as a light emitting diode (Light Emitting Diode, LED) to excite the quantum dots to emit high-chromaticity pure color light, its luminous characteristics have far exceeded the luminous characteristics of LED backlight phosphors. Therefore, packaging Quantum tubes with quantum dots are widely used in the field of liquid crystal display technology. [0003] At present, quantum tubes are usually formed by sealing quantum dots with transparent materials. However, due to the single structure and single application scenarios of existing quantum tubes, they cannot meet the different needs of different light sources. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a light emitting ...
