Big coffee business executives gathered to discuss the LED Market

The day before, Taiwan CREE (CREE), crystal power, bright sharp (Lumileds) and OSRAM (OSRAM), Linsen LED manufacturing executives of companies gathered to focus on the market opportunity, CSP (Chip Scale Package; wafer level package) to explore the technology and application of terminal.

LED development still need to pay attention to the balance between supply and demand

EPISTAR Business Center Associate Zhang Zhongxing said that the past is good at wafer production Jingyuan photoelectric photoelectric semiconductor, as a major supplier of lighting in the value chain of the most upstream and downstream in recent years began to move, try to cut into the packaging market to create new business models. Zhang Zhongxing said that although the LED application market, the annual growth rate (CAGR) for the single digits, but at least still growing, so the overall market situation is relatively good. However, the supply of LED, to some extent still depends on the terminal application demand, with the passage of time, such as TV, tablet, street lamps and indoor lighting, in order to play the LED application to the sea, so the balance of supply and demand for the development of LED is still quite important.

CSP (wafer level packaging) technology manufacturers optimistic optimism

About CSP technology, OSRAM Opto Semiconductor solid-state lighting division product definition director Ralph Bertram said, will power and to divide the $/ lumens product positioning, various manufacturers actually have similar product layout. However, CSP really can correspond to all of the product? In fact, LED chip packaging is very diverse, many vertical Chip (Flip) package, but most of the cost is very high. If other packaging practices, although effectively reduce costs, but may be in the performance of a discount. If the industry can work together to create a new ecosystem, further efforts to solve the problem of packaging technology, that is, it is possible to solve the problem.

Continuation of the discussion of Ralph Bertram technology in the CSP, Xie Wenfeng, vice president of Asia Pacific vice president of sharp Trading Co., Ltd. expressed a more optimistic view. He said, CSP is not a new technology in the semiconductor field, this technology has been developed for a long time, only being used in the LED package and terminal products, such as smart mobile phone flash, a directional light source, light source, lamps and omnidirectional courtyard lamp etc.. Xie Wenfeng uses PHILPS lamp as an example, the flip chip technology bring benefits, like in the heat and illumination are quite good, the integration degree and size, also have very good performance.

Xie Wenfeng further said, because CSP involves very widely from system integration perspective, each knot is linked together, to achieve the best heat dissipation problem, must spend a lot of time, which covers many knowledge and technology, it is unlikely to be copied in other manufacturers.

LED lighting applications should be based on consumer thinking

The general manager of Taiwan Linsen Wang Chieh is based on the global market of about LED future development opportunities and challenges. Wang Chieh said that as of 2019, the global lighting market size will reach $128 billion 700 million, application categories, general lighting lighting applications accounted for all 80% of the share, which, with the highest proportion of residential applications, which is one of the important applications of Linsen quite positive market.

Wang Chieh pointed out that with the expansion of the LED lighting market, coupled with the average price to reduce, causing consumers to buy, but also attract a lot of business investment. Some industry that application of seemingly huge business opportunities to get into the relatively so like a swarm of bees, which further caused vicious price competition, stuffy head work of an application, if consumers do not pay, but also not conducive to the company. He believes that the industry should be thinking about the needs of consumers, and then put into more appropriate.

Integrated system thinking to enhance the lighting experience

Chen Fulong, general manager of CREE Electronics (Cree) Asia Pacific Marketing Department, the development of the lighting market in the perspective of system integration. He said, "BetterLight" will change everything around people, such as the environment, design, and even the emergence of open innovation. CREE recently partnered with CISCO, the use of POE (power line Ethernet) technology in the field of networking layout, and through such as Bluetooth and Wi-Fi technology to control the lighting changes, to further enhance the user experience.
