In this “ultra-thin profitable†era, there were competitors competing in the sea to cut down on prices and killing red eyes. After that, the big brands stepped up their efforts to compress the living space. Taiwanese manufacturers, how can you survive? It seems that giving up the shackles of the traditional model of OEM and investing in the embrace of independent technology is the right direction for successful profitability.
Guanghai Technology is located in a quiet lane near the Hsinchu Science Park. On this day of visit, Guanghai was busy as usual, and many competitors were internationally renowned big manufacturers, so that they could not afford to relax. The internationally renowned victory program is being portrayed in every corner of the Guanghai office area.
At the entrance, Zhuang Yongfu, general manager of Guanghai, greeted us with a smile. Zhuang’s general manager is a native Taipai in Taiwan. He is straightforward and cordial, just like the diligent Taiwanese cow, working hard for Taiwan’s independent technological innovation.
Designing with the nature of LEDs
Light Ocean is still very young. It was founded in May 2009. It is only three years old and it is full of vigor and energy. Leaders are also very far-sighted, seeing the current LED industry, although the same group, and fierce competition, but the existing technology is like a long carriage, manufacturers of their own affairs, chaotic. One thing that speaks of domineering is that some people come to the surface of the LED specifications of the LED industry. To put it practically, it is in the troubled times that there are products that can really convince consumers that they are not buying quality products that are not uniform.
While introducing the company, Zhuang General Manager lined up Guanghai's proud products. These are LED bulbs using COHS technology. COHS (Chip On Heat Sink) is the result of Guanghai R&D team's efforts over the years. As the name implies, LED chips are directly placed on the heat sink, which not only saves materials, but also improves heat dissipation efficiency, and helps improve the luminous efficiency.
Zhuang’s general manager said that in recent years, with the LED lighting and heating in the market, it has indeed attracted a large amount of investment from manufacturers and also has witnessed huge business opportunities. However, when the market grabs the LED benefits, it forgets the nature of LED. The essence of LED is light and heat. In other words, LED emits light while it keeps heating. Most of the companies that have invested in it are only paying attention to the benefits brought about by LED "light", but they ignore the lethality of "heat" for LED light efficiency and service life.
If you can't use the correct method to deal with the problem of LED heating, not only the quality of the LED can not be guaranteed, but also completely contrary to the nature of LED products. This problem is very serious in the current LED market. "The market only sees light, and manufacturers of course only care about light. This is the situation we least want to see."
There is no standard in the LED market, and bargain prices all over the world. Customers only look at prices, and it is very common to ignore quality. Anyway, if it can be bright, the customer does not care much about what is behind this luminosity. What kind of knowledge or deep technology is hidden?
However, the general manager of Zhuang still stressed that the market’s price war does not mean that everyone should sink with it. There is always an upward power to influence the industry and change the industry. This is exactly what Guanghai is doing. With independent technology and innovation instinct, we have come up with a different path. "We want to use the essence of LED products to carry out LED thermal design." Zhuang General Manager said so.
Take your own path with subtraction concept
LED needs to be antipyretic, and how hot the solution is, is a university asked. The general manager of Zhuang said that as long as LEDs do a good job of cooling, they can improve the quality of LED and the cost is lower. In fact, the key to LED heat dissipation is one-time heat conduction and secondary heat dissipation, that is, the heat emitted by the LED while emitting light first, and then heat.
In this process, including the material of the carrier board, the packaging method, etc., are the key.
The focus of LED packaging is nothing more than sending light out and exporting heat. The design of heat conduction requires the accumulation of experience. Gwanghae itself started from the IC carrier board. Although it has only been established for three years, it has accumulated seven years of carrier board technology and experience. Reaching the LED lighting industry, it is naturally handy for heat conduction.
"Mastering our own technology has made us a true problem solver." Zhuang said that other LED competition vendors that do not have similar technologies will mostly deal with the issue of heat dissipation, but this is just a matter of throwing the problem to others. Not only is the quality of the product hard to grasp, but the problem cannot be solved effectively. Guanghai, from material selection to carrier board design, can be single-handedly. Can really solve the problem, of course, can give a better product.
In fact, LEDs will consume 80% of their energy to heat, and only 20% will become light energy. The Guanghai strategy for heat dissipation is to adopt the concept of "subtraction". Starting from the core, the architecture will be simplified, the heat conduction will be faster, and the temperature will be reduced. Therefore, the package can be far lower than the thermal resistance value of the industry. structure.
The carrier board in COHS technology is made of copper metal whose thermal conductivity is second only to silver. Guanghai also has more than 30 patents. The general manager of Zhuang pointed out that the current reason why most manufacturers do not use copper carriers is because they fear that copper will expand due to thermal expansion and damage the overall structure without using it. However, this problem does not exist in the COHS because the COHS has a good package structure, which allows the heat energy generated by the LED to be quickly exported to the heat dissipation system for further removal.
So far, Guanghai's COHS technology has been able to solve the unsolved LED heat problems in the market, including hundreds of watts of high-wattage LED lamps, can be used for street lamps, store lights and other applications; in addition there are low wattage The bulb light, because Guanghai has the advantage of LED heat dissipation, so when the market can only see 8W, 10W light bulb, Shanguang Technology has adopted the Guanghai program has developed 12W or even 15W. High-luminance light bulbs.
"Even if an opponent also launches the same wattage product, but once the temperature is measured, it is more than 20 degrees higher than ours. The problem lies in the design of heat dissipation." Zhuang General Manager said: "This is the key to winning." Even if the opponent wants to chase, it will not catch up."
