Problems solved by technology
Most of the existing reflective layer materials are metal materials, but the reflectivity of this reflective layer is not good, resulting in the reflected light energy being absorbed by other material layers of the light-emitting diode, which cannot improve the luminous efficiency of the light-emitting diode, and This reflective layer will interdiffuse with other metal layers
[0005] In order to solve the above problems, a reflective layer composed of a metal material and a dielectric material has been developed, but this reflective layer can only improve the phenomenon of interdiffusion with other metal layers, but still cannot improve its reflectivity. The improvement of diode luminous efficiency is still limited

Embodiment Construction
[0045] Such as figure 1 As shown, the light-emitting component 1 with a reflective layer of the present invention includes a light-emitting diode 10 and a reflective layer 12. The light-emitting diode 10 includes a substrate 101 and an epitaxial structure 103. The epitaxial structure 103 is arranged on the substrate 101. The reflective layer 12 can be according to The light emitting direction of the light emitting diode 10 is set. The reflective layer 12 of this embodiment is disposed on the substrate 101 of the LED 10 and is opposite to the epitaxial structure 103 .
[0046] The reflective layer 12 is made of a variety of dielectric materials and does not include metal materials. Because the reflectivity of traditional reflective layers made of metal materials is not high, this embodiment uses a reflective layer 12 made of a variety of dielectric materials. The problem of low reflectivity of the traditional reflective layer made of metal materials is improved to prevent the ...

The invention discloses a light emitting component with a reflecting layer, wherein the reflecting layer comprises a plurality of dielectric layers; the dielectric layers have more than two types of material, and the dielectric layers have more than two thicknesses, thereby forming various types of reflecting layers with the different structures, but except the combination that the dielectric layers have two types of material and the dielectric layers have two thicknesses. The reflecting layer provided by the invention can be applied to all types of light emitting diode to form a new light emitting component; and the light emitting efficiency of the light emitting component can be increased since the reflective layer has excellent reflectivity. The invention further discloses a structure of the reflective layer.
Description
technical field [0001] The invention relates to a light-emitting component, in particular to a light-emitting component with a reflective layer. The invention also relates to a structure of the reflective layer. Background technique [0002] Light Emitting Diode (LED) is a light-emitting component made of semiconductor materials. The component has two electrode terminals, a voltage is applied between the terminals, a very small current is passed through, and the remaining The energy is excited and released in the form of light, which is the basic principle of light-emitting diodes. [0003] Light-emitting diodes are different from ordinary incandescent light bulbs. Light-emitting diodes are cold-emitting, and have the advantages of low power consumption, long component life, no need to warm up the lamp, and fast response. In addition, they are small in size, resistant to vibration, suitable for mass production, and easy to use According to the requirements of the applicati...
