Hongli Optoelectronics: The package will usher in the peak in the next five years

[Source: LED Engineering's "good LED products," May issue of the magazine reporter / Zhu Chunwei] February Development and Reform Commission and other six ministries jointly issued the "energy-saving semiconductor lighting industry planning", the new LED bulb as to promote their products. LED bulbs are included in the subsidy industry, opening a new era of LED indoor lighting, and also indicating the arrival of the LED lighting era. A series of favorable policies such as national policies have stimulated the entire industry of LED to usher in a good development period and step into the fast lane of development.

According to the research report of the High-tech LED Industry Research Institute (GLII), the penetration rate of global LED general lighting output has shown a geometric growth trend in recent years. The penetration rate in 2010 was only 5.0%, reaching 12.2% in 2012 and rising to 20.5% in the first quarter of 2013. It is estimated that by 2017, the global LED general lighting penetration rate will reach 80.1%.

"I personally agree with the data forecast of senior engineers. I believe that LED lighting will account for 70%-80% of the lighting market in the next five years. But reaching this peak in 2017 means that the industry's rising trend is basically over. Industry competitors and manufacturers will also tend to be stable, and the industry's major integration is basically completed." Wu Gan, executive deputy director of Hongli Optoelectronics Technology Center, told reporters at the 2013 Zhongshan Lighting Quality Upgrade Strategy Conference.

The LED package substrate market will reach a compound annual growth rate of more than 20% in 2012~2017, and will grow to nearly $900 million in 2017.

"At present, the LED packaging industry is still in the stage of climbing. In terms of materials, the future of ceramics will be a major trend, and will also be well applied and promoted in some sub-segments, such as plant lighting. The Japanese company is mainly based on ceramics. However, the metal substrate is more in line with the current domestic market, and Hongli is still mainly based on metal packaging." Wu Gan said when it comes to packaging materials, the metal substrate remains for a long time. It is the mainstream of packaging, especially in the case that large factories such as Philips have not used colored porcelain.

Where does the metal VS ceramic package go?

With the rapid spread of LED lighting and the continued improvement in packaging requirements, what packaging will lead the way in the future? At present, there are still major differences in the industry regarding metal substrates and ceramic substrates.

In terms of materials, the future ceramic substrates will be a major trend, and will also be well applied and promoted in some sub-segments, such as plant lighting. “The ceramic substrate is well-suited for its application in the field of plant lighting because of its good insulation and stability. Our C3535 has high power and high efficiency, and is universal for 1W and 3W.”

When Wu Gan talked about packaging materials, he said that he is more optimistic about metal substrates, which is more in line with the current domestic market. Hongli is still mainly based on metal packaging.

Ceramic substrates are not as good as metal substrates in terms of heat dissipation and reflection (increasing light efficiency), and are also more expensive than metal substrates. In the case that large factories such as Philips have not yet adopted ceramics, metal substrates are still the mainstream of packaging for a long time. The key to future COB packaging competition is in terms of standardization and cost-effectiveness.
