The international photonics exhibition Photonics West 2018 is now the largest one in the US and has a lot of visitors. Taking place annually in San Francisco, Photonics West 2018 is the world's largest event for the optoelectronics industry

The international photonics exhibition Photonics West 2018 is now the largest one in the US and has a lot of visitors. Taking place annually in San Francisco, Photonics West 2018 is the world's largest event for the optoelectronics industry. HPL is one of the well-known manufacturers of UV LED and IR LED. It has sufficient experiences in cooperating with chip manufacturers, developing packaging products and designing optical system. By combining the above three main advantages, it develops UV and IR packaging products. The UV products have been applied in the curing market. The irradiance can reach 8W/cm2 at a distance of 10cm. IR LED products have also been shipped to NB and applied in the facial recognition market. At Photonics West 2018, LEDinside had the pleasure to interview HPL’s President Charles Wei for sharing HPL’s current UV-C LED technology and the market development trend.

According to the latest report from LEDinside, a division of the market research firm TrendForce, 2017 UV LED v.s UV LED Module Market Report, UV LED products consistently develop in various applications, plus the Minamata Convention on Mercury and energy saving policy, LEDinside forecasted that UV LED market scale will raise from USD 288 million in 2017 to USD 526 million in 2020, CAGR of 2015-2020 is highly at 34%.

In 2016, UV LED technology has been rapidly expanding into various application markets including curing, sterilization and purification equipment. The total value of the UV LED market worldwide is estimated to grow from US$166 million in 2016 to US$555 million in 2021 at compound annual growth rate (CAGR) of 27%, according to the 2016~2021 Global LED Industry Demand and Supply Database Report byLEDinside, a division of TrendForce.

The combined shipments of smartwatches and smart bands will reach 7.5 million units this year, and 90% of which will be equipped with optical sensor components used for pulse rate monitoring, according to the 2016 UV LED and IR LED Application Markets Report by LEDinside, a division of TrendForce. Shipments of smartwatches and smart bands together will total 170 million units by 2020, and all of them are expected to incorporate optical sensor components. A common sensor system that measure pulse rate and blood oxygen concentration is the reflective photoplethymography (PPG) sensor. Due to opportunities in health and fitness trends, the reflective PPG sensor is gradually becoming an integral part of most wearable devices. Additionally, wearable optical sensors that can track pulse rate and other health-related data have huge potential in the home healthcare market.

LEDinside, a division of the global market research firm TrendForce, held an exclusive analyst symposium on April 15 at Taipei World Trade Center Nangang Exhibition Hall. During this special meet-and-greet event, LEDinside analyst based in Taiwan and Mainland China gathered together to share their latest findings with attendees. The main topic of the symposium was the growing niche or “Blue Ocean” markets for LED technology, such as UV LED, IR LED and automotive LED products. The LEDinside team also gave attendees a comprehensive overview of market outlooks and opportunities from a regional as well as a global perspective, with focuses on China and the emerging markets.

UV-A LEDs are primarily used for curing. Presently, curing also represents 52% of the UV-A market in terms of applications. Wu noted that UV-A LED manufacturers will evade the challenge of price competition by offering highly customizable solutions in the future. This means working closely with curing machine vendors in every aspect of product development, such as the LED wavelength, the design of the UV LED module, the composition of the UV adhesive and the design of the cooling system.

Light-emitting diode (LED) manufacturers are now looking to develop niche application markets that can provide higher margins as the price competition in the LED lighting market has become too difficult for them. Among these niche application markets, ultraviolet (UV) LED has attracted investments from many manufacturers because of its enormous market value. The UV LED market has much higher technological barrier to entry, so prices of its products are several tens of times greater than those of the general LED products. LEDinside, a division of TrendForce, states that the global UV LED market in 2015 is estimated at US$122 million, which is around the same level as in 2014, in its 2015 Global LED Industry Supply and Demand Database Report. The absence of noticeable growth in the market value this year is mainly attributed to the rapid decline in UV-A LED prices (UV-A spectrum is between 320~400nm in wavelength).

Many types of laser diodes (LDs) were displayed at OPIE’15, which took place last month in Yokohama, Japan. LD can be classified into gas laser, YAG lasers, semiconductor lasers, quantum cascade lasers and others.
