Due to the poor thermal conductivity of the sapphire substrate, the luminous efficiency of the LED is affected. In order to solve the heat dissipation problem of LED, it is possible to mainly adopt the architecture of vertical structure LED in the future to promote the technological development of the LED industry. Regarding the vertical structure LED technology, I believe that everyone has heard of it. The following is only a description from the technical surface, for your reference.
We know that LED chips have two basic structures, the lateral structure (Lateral) and the vertical structure (Vertical). The two electrodes of the lateral structure LED chip are on the same side of the LED chip, and the current flows laterally in unequal distances in the n- and p-type confinement layers. The two electrodes of the vertical structure LED chip are respectively on both sides of the LED epitaxial layer, and since the patterned electrode and the entire p-type confinement layer serve as the second electrode, the current flows almost entirely vertically through the LED epitaxial layer, and there is little lateral flow. The current can improve the current distribution of the planar structure, improve the luminous efficiency, and can also solve the problem of the P-pole shading and improve the luminous area of ​​the LED.
Let us first understand the manufacturing technology and basic methods of vertical structure LEDs:
There are three main methods for manufacturing vertical structure LED chip technology:
First, the use of silicon carbide substrate to grow GaN film, the advantage is that under the same operating current conditions, less light decay, long life, the disadvantage is that the silicon substrate will absorb light.
Second, the use of chip bonding and stripping technology. The advantage is that the light decay is small and the life is long. The disadvantage is that the LED surface needs to be processed to improve the luminous efficiency.
Third, the use of a heterogeneous substrate such as a silicon substrate to grow a gallium nitride LED epitaxial layer, the advantage is that the heat dissipation is good and easy to process.
There are two basic methods for fabricating vertical structure LED chips: stripping the growth substrate and not stripping the growth substrate. The vertical structure GaP-based LED chip grown on the gallium arsenide growth substrate has two structures:
The conductive gallium arsenide growth substrate is not stripped: a conductive DBR reflective layer is laminated on the conductive gallium arsenide growth substrate, and a GaP-based LED epitaxial layer is grown on the conductive DBR reflective layer.
Stripping a gallium arsenide growth substrate: a layered reflective layer on a GaP-based LED epitaxial layer, bonding a conductive support substrate, and stripping the gallium arsenide substrate. The conductive support substrate includes a gallium arsenide substrate, a gallium phosphide substrate, a silicon substrate, a metal and an alloy, and the like.
In addition, vertical GaN-based LEDs grown on silicon wafers also have two structures:
The silicon growth substrate is not stripped: a metal reflective layer or a conductive DBR reflective layer is laminated on the conductive silicon growth substrate, and the gallium nitride-based LED epitaxial layer is grown on the metal reflective layer or the conductive DBR reflective layer.
Stripping the silicon growth substrate: laminating the metal reflective layer on the gallium nitride-based LED epitaxial layer, bonding the conductive support substrate on the metal reflective layer, and stripping the silicon growth substrate.
The process of manufacturing a vertical gallium nitride-based LED is briefly described. The layered reflective layer is on the gallium nitride-based LED epitaxial layer, and the conductive support substrate is bonded on the reflective layer to peel off the sapphire growth substrate. The conductive support substrate includes a metal and alloy substrate, a silicon substrate, and the like.
Whether it is a GaP-based LED, a GaN-based LED, or a ZnO-based LED such as a through-hole vertical structure LED, it has a larger advantage than a conventional structure LED, and the specific performance is as follows:
1. At present, the existing vertical structure LEDs of all colors: red LED, green LED, blue LED and ultraviolet LED can be made into a through-hole vertical structure LED has a great application market.
2. All manufacturing processes are performed at the wafer level.
3. Since there is no need to connect the gold wire to the external power source, the thickness of the package of the LED chip with the vertical structure of the through hole is reduced. Therefore, it can be used to manufacture ultra-thin devices such as backlights and the like.

This project Gannan quality navel orange whole fruit (not peeled) as raw materials, using self-developed patent Orange surface sterilization technology to maximize retained a whole pieces of all Orange essence (Orange: Shun Qi, phlegm, pulp: fiber laxative, fruit seeds: allergic inflammation, juice: whitening detox).



Conventional enzyme production is mainly produced by hand, hand-sliced, hand-fermentation, the company every step of the process are used self-developed technology and equipment to automate production. Moreover, the conventional enzyme production have adopted a fermentation technology, enzyme often taste discomfort, sour and other issues, I produced using a variety of enzymes, probiotics composite grade fermentation technology, fermentation at different times with different strains, and two or three times through fermentation, enzymes such pure taste, streptozotocin balanced nutrients. Scientific and standardized process:

I produced using enzymes navel cleaning, sterilization, slice, fermentation (fermentation grade composite multi-strain), solid-liquid separation, bottling and other steps. Each step developed a patented automated production equipment, fully automated production, to avoid the traditional manual production workers are not standardized, easy to pollution, low production efficiency, product quality is unstable defects.

Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
