 'We also need to run schools, train how to do distribution, and teach people how to do management. It is not impossible for people to use private jets in the future. In fact, Company's leadership style is more fully reflected in the crisis transformation after successful entrepreneurship.

This is a deeper issue that business operators must think about. In 2009, the renminbi continued to appreciate and manufacturing costs rose accordingly. The big ship turns around as fast as the boat, and fluctuations in the integration process are inevitable. In previous years, a bread machine store in Beijing could sell hundreds of thousands of dollars on National Day, but in 2014 National Day promotion, only 6 items were sold in two or three days.

The major electronic cities in Zhongguancun, Beijing, which have been booming for 20 years, have now been used by various technology and financial startups and incubators, and even supermarket stores. The most rare thing is that he can quickly find the core and essence of the problem. Isn't this competition in the same industry? In this regard, Company said: “The price must IP65 waterproof led floodlight be fair, otherwise the small and medium shareholders will sue. He is still looking for opportunities on a global scale, hoping to realize the dream of a 'world-class company' as soon as possible through mergers and acquisitions. I am the principal. Acquiring a brand is not as simple as buying a toy.

Five years later, Company founded China Resources Electric Company, the predecessor of Dhow, and became the 'Breader King' with more than 90% of the global market. Then, what should dealers do? Company frequently visits distributors in various places to talk to them about his system integration product system and channel transformation ideas, and talk about equity acquisitions. More than 20 years of turbulent waves have made him instinctively sensitive to trends. Company is determined to transform. After more than a year, Company made the oven the world's first in the same way

42%, and the coated light attenuation is 11. In 2015, it was reported that Flori Optoelectronic Materials (Suzhou) Co. The full name is 'Restriction of Hazardous Substances' (Restriction of Hazardous Substances).

Recently, Flori Optoelectronic Materials (Suzhou) Co. Figure 1. Because of the development of industry and the increase in the number of locomotives, the environment is full of exhaust gas. C16 is a polymer coating based on silicon, and more than 50% of the composition is water. independently developed an environmentally friendly, high anti-sulfurization performance LED aqueous solution coating C15. In follow-up reports,

other optoelectronic material improvements and disruptive innovation technologies of Flori Optoelectronic Materials (Suzhou) Co. LED water-soluble coating technology with high anti-vulcanization performance: accelerated vulcanization test results (condition: 16 hours comparative test of sulfur powder at 80 degrees).

After vulcanization at 80 degrees for 16 hours, the uncoated light attenuation is 42. C16 is applied to COB/large-scale integrated LED aging at 180℃ and 200℃ for 9h. Recently, Flori Optoelectronics Materials (Suzhou) Co. In addition, C16 coating has excellent spreadability and is a product that can be applied to COB/large-scale integrated LED devices (Figure 2).

Due to the relatively wholesale Portable Light wafers in the functional area of ​​high-power LED devices, C15 has insufficient solution wettability, which limits its application in large-scale integration. Figure 3. Due to its excellent anti-vulcanization properties on SMD devices, C15 has been certified by a leading LED packaging company and has been trial-produced on the production line., Ltd., Ltd.

 This increase in efficiency makes high-brightness chips smaller, and can generate an addressable matrix from a densely stacked array, which is very suitable for dynamic beam steering of automobile headlights. However, the net reflectance gain of the thin film design may only be significant for relatively high sapphire thicknesses.

As the carrier density in the quantum well increases, the Auger loss is significant at high driving currents, which enhances the possibility of the three-particle recombination process. From the perspective of photon jumping, the two flip-chip designs have a strong dependence on the thickness of the sapphire, which is better than the thin-film structure (see Figure 4). Improvements can be made by switching to semi-polar and non-polar substrates to reduce or eliminate the polarization induced electric field in the active area.

Figure 2. The efficiency of LEDs continues to improve at an alarming rate, not only reducing the number of LEDs for a given application, but also reducing the cost of the hardware system, thereby increasing the adoption rate and reducing costs. The wide penetration of LEDs into various markets is attributed to the significant increase in the efficiency of blue LED plugs, white conversion efficiency, precise customization and color point control.

Note that for higher wholesale Led street lamps emission angles, the average number of photon jumps suddenly rises, consistent with the critical angle of the GaN-sapphire or GaN-siloxane interface. With a flip-chip structure, the sapphire needs to be thick enough to prevent a lot of photon jumping-for example, at least 100 mm for a 1 mm2 chip. Comparison of thin film (TF) and flip chip (FC) designs: (a) thin film (b) single-sided low emitter based on flip chip (c) five-sided emitter based on flip chip. Generally, an increase in indium content in a low Droop active area design will result in a decrease in material quality.

The mature LED silicon substrate technology also makes ;AFS have more stable temperature characteristics. Unless there is a wide-angle DMD device specially customized for headlights in the future. The first \;AFS that has been launched, Osram’s EVIYOS, can achieve 1024 pixels on a Wholesale Solar led light Factory single chip of 4mm;4mm, and a single pixel achieves a luminous flux of 3lm. The advantage of LED+DMD is that the technology is relatively mature, and the main parameters such as brightness and efficiency are also good enough.

ADB (Adaptive Driving Beam) market share trend assessment No matter what kind of intelligent lighting action is implemented, the core of its light source technology is to divide the far and near light types into multiple areas with varying numbers, and based on the data of the camera or sensor Input and preset algorithms carry out switch control or brightness adjustment for each area.

And \;AFS integrates a matrix-type CMOS control circuit in the silicon substrate of the chip in advance, and combines it with the chip that is also processed by the matrix-type microstructure to realize the separate opening and closing of each independent microstructure area on the chip. The main limitation is that the optical efficiency is relatively low due to the loss of the polarizer and the liquid crystal panel, and the improvement space is effective in principle.01 Introduction:

The development trend of smart headlights The concept of headlights that change the light type according to different road conditions was first proposed in 1958, but it was technically difficult to achieve in the era when halogen lamps were the main light source of headlights. The currently available \;AFS pixels are in the order of 1,000, and are expected to be upgraded to 10,000 in the next few years. Figure 3 Example of LCD-style smart headlights (picture source: HELLA official website) (3) DLP-style and LCD-style smart headlights are developed for similar reasons, as the current mainstream technology of projection equipment based on DMD devices (Digital Micromirror Device, Digital Micromirror Device) )

 The new module led portable lights factory is 6 cm x 10 cm, and the pitch is about 700 µm or less. After a lot of hard work, this year has finally made the red light 'bright'. Micro LED technology has been discussed for many years. Fang Yanxiang explained that the Micro LED chip must first be bonded to a temporary substrate made of silicon or glass during the manufacturing process, and then the sapphire substrate is removed by laser lift-off, and then the original LED structure is flipped in the form of flip chip.

Face down, and make the P-type and N-type electrodes on the same side, which is more difficult for Micro LEDs that are scaled down to the micron level. A slight improper pressure may reduce the success of red light transfer. Under certain power consumption requirements, it is very difficult to reach 100,000 nits. Weakening the structure is a key to the success of mass transfer. In particular, red light is limited by materials and characteristics, and perhaps even a 50% yield may not be achieved. The Mini LED display module of Taiwan Industrial Technology Research Institute adopts PCB substrate,

the module size is 6 cm x 6 cm, the pitch is less than 800 μm, and the resolution is 80 x 80 pixel. Fang Yanxiang, deputy head of the Intelligent Application Microsystem Group of the Institute of Electro-Optics of Taiwan Industrial Technology Research Institute, mentioned two major technical problems. Last year, the passive matrix drive ultra-fine-pitch Micro LED display module developed by Taiwan Industrial Technology Research Institute and the third factory successfully transferred the Micro LED array chip directly to the PCB substrate, but the RGB full-color only lacks red light. Just looking at the yield rate of the available area is not enough.'

Fang Yanxiang took a 4-inch LED wafer as an example and pointed out that after the wafer has an outer diameter of 2 mm, the yield of the usable area is It may reach 99% under a single standard value, that is, just look at the wavelength (Dominant Wavelength, Wd), the driving voltage (Forward Voltage, Vf) or the reverse leakage
