Tang Guoqing: LED lighting era comes

Come on, LED lighting era;

Say no letter also helpless, LED achievements of an era;

Opponents have it, history does not matter;

Those who laugh at it will be abandoned by the trend;

Cherish it, time is like an arrow;

Work hard, or you'll lose your job;

Where did the time go?

Time is dedicated to the bright LED lighting era.

At present, the rapid development of LED lighting technology. Here, I would like to talk about personal LED technology and the market point of view.

1, substrate, substrate material, three arrows

In the field of the substrate, the current development situation of the substrate material, can use arrows shot eight words to sum up. In the past, mostly based on sapphire and silicon carbide substrate, and this year there is the addition of silicon materials, competition has become intense. For example, Toshiba, Samsung, TSMC and other giants have recently released a silicon substrate LED chip, optical efficiency has reached 140lm/w. Here, in particular, the silicon substrate material is also a lot of domestic enterprises to do, but the domestic silicon substrate is mostly 2 inch start, while Samsung, Toshiba and other international brands are starting to be 8 inches. Understanding of the substrate materials, friends know, 2 inch piece and the gap between the size of 8 inches. We have not taken off, it has lagged far behind international enterprises, and this is our gap with foreign countries.

2, chip: flip chip, a sudden emergence

In the field of chips, flip chip technology is emerging, especially in high-power, outdoor lighting applications market will be more popular. Flip chip technology has obvious advantages in the following: it is not through the sapphire heat, can pass a large current; the two is the size can be smaller, easier to match the optical; three is to enhance heat dissipation, so that the life of the chip can be increased; the three is to enhance the ability of anti-static; four is to lay the foundation for development the subsequent packaging process. Therefore, it is suggested that enterprises can pay more attention to the flip chip technology, especially those who play high power.

3, packaging: chip packaging, subversion tradition

In the field of packaging is also a huge subversion. For example, there is a Taiwan called "free chip" technology, the industry also showed a different attitude, some blind, that no chip packaging technology is fake and bluff; others oppose and conflict, to think it should be for manufacturers to bring trouble, some pain; is that this chip package without cannot be comparable to COB, COB occupy absolute advantage. I think, chip package technology has the following characteristics: one is to adopt direct chip eutectic welding pad at the bottom of the package, simplifies the production process, reduce production costs; two is no bracket, thermal resistance is greatly reduced, the same volume of the device can provide greater power; the three is the package form smaller, closer to the point light source. The user terminal lighting design more flexible. Chip packaging is not to add trouble to downstream applications, on the contrary is to bring greater convenience to the application of the manufacturers.

4, application: lighting manufacturers, shopping channels

In downstream applications, lighting manufacturers are shopping channel. Here, we have to see that the new LED companies to enter the field of lighting is to do what kind of way? First displacement and beyond. However, whether it is to replace or beyond, the road is lighting; and the original lighting companies? They are on their way, LED is just an upgrade. A brave man, but I think this brave than traditional lighting manufacturers meeting bigger.

5, major: Wen Road has specialized.

Here, I thought of the Tang Dynasty writer Han Yu said: I have successively, specialize in. This year, the LED market specialization division will further develop. For example, OEM companies like Fujian leedarson, as is done for many years, East Southern China have several large ODM professional Street generation factory, some annual output can reach hundreds of thousands of lanterns. Some large enterprises in order to improve market share and brand influence, the products they need will be more refined classification, which is more focused on doing a single product OEM business opportunities.

6, a single: simplify, simple

"To be or not to be" will become a rule of business survival, like FSL, only the lamp bulb, only Linsen lighting lamp, the history of Ford first only for a class of grille lamp series products manufacturers, bigger and stronger relatively more difficult. Open the palm of the hand is better than clenched fist, do their own single category, and to achieve the ultimate product of this kind, so that the highest price, the most reasonable, you stand in the market. In addition, with the increase of labor costs, enterprises should strengthen the automation of the production process.

7, control: intelligent control, fascinating

In the product development trend, I think, smart home, smart office, smart lighting will be the future trend, LED smart lighting will be an important growth point to increase the added value of semiconductor lighting. For example, using a mobile phone or PAD direct remote control LED lights, through the design of the manual and even intelligent memory function; in different time and the scene automatically adjust the lighting mode; from indoor lighting to outdoor lighting intelligent control.

8, equipment: intelligent equipment, maturing

With the demographic dividend
