Market Trends of LED Encapsulation Industry
This section covers the major market trends shaping the LED Encapsulation Market according to our research experts:
Silicone Encapsulant is Expected to Witness Significant Growth
- Silicone encapsulation has picked up momentum in the past few years as the material of choice for encapsulation of LEDs, owing to its flexibility and operating capability over a wide range of temperatures, though could have reliability issues in cold weather applications.
- Organic silicones have been utilized as encapsulant materials for light‐emitting diodes (LEDs) for several years, while their performances need to be updated in order to meet the requirements of high‐power LEDs. They have been the material of preference for LED packaging due to their outstanding transparency and stability at operating temperatures.
- Silicones are not only utilized as encapsulants to protect LED devices but also as the polymer matrix for phosphors to convert blue LEDs to white LEDs. With commercial silicones, LEDs have refractive index mismatches at the silicone/LED chip and silicone/phosphor interfaces. This mismatch leads to reduced light transmission and trapped light with-in the LED device. Better light extraction can decrease intrinsic heating, in turn decreasing the dependency on heat transport materials and enhancing reliability.
- Moreover, the demand for the silicon type is primarily due to the strong demand from commercial LED lighting. The advantages silicone encapsulants provide, such as thermal transfer and light emission, are in line with the addressable need of mid- and high-power LEDs, the silicon segment is expected to grow at a substantial rate, during the forecast period.

Asia-Pacific is Expected to witness Significant Growth
- The Asia-Pacific region is expected to witness a significant growth rate during the forecast period. UNEP in the frame of enlightens program estimates that in the absence of new policies, 57% of the lighting energy demand by 2030 would come from Asia.
- Geographically, the market is widespread in the region owing to the availability of plenty of encapsulation raw material. Assertive demand growth from the consumer electronics and automobiles industry in this region, where rapid changes in technology, is resulting in greater demand for high and medium power LEDs is expected to drive the demand for encapsulation products.
- Moreover, huge demand for silicone encapsulants is also expected from countries in this region such as South Korea and Taiwan, primarily owing to the large production of consumer electronics like TV, tablets, and monitors.
- Furthermore, China is assumed to be an important revenue generator, as it holds a major share in the LED market, followed by Taiwan. Also, Australia, which is amongst the top 10 LED importers, in the world is also driving the growth of the LED encapsulation market.
