Improvements in UV-LED flux density, stability and life hours have made UV LEDs a viable solution for replacing traditional UV light sources such as mercury arc lamps, arch lamps, hot and cold cathode lamps and grid lamps. UV LEDs are more environment friendly as they do not contain harmful mercury, they do not produce ozone and consume less energy as well. These major advantages uplift the demand of UV LEDs, particularly using Silicon Carbide and Gallium Nitride materials which is expected to propel its market growth in forecast period. UV-C LED usage is rapidly growing in applications such as germicidal (UVGI) for air, surface and water purification.
UV LED Market Segment Analysis – By End Use Industry
UV LEDs are widely used for different Healthcare and Sterilization applications and are projected to grow at a CAGR of 23.4%. UV LED Curing uses light-emitting diodes which convert electrical current into light. When the electrical current flows through an LED, it gives off ultraviolet radiation. The ultraviolet light causes chemical reactions in the molecules within the liquid, forming chains of polymers until the liquid becomes a solid. This process is a new technology which was designed to provide solutions to many of the issues found in traditional UV curing and heat-set drying. UV LED curing offers all the benefits of traditional curing, and also provides solutions to the negative environmental impact. This new technology reduces heat radiation and offers instant on-and-off switching. UV LED curing also does not require the use of moving parts which further reduces the amount of energy required. All these advantages tend to boost its demand in Healthcare and Purification industries which uplift its market growth.

Thus, the demand for water sterilization and purification processes is of great extent. This demand enhances the market growth of UV LED in this region. According to World Bank Reports, investments done in water and sanitation in Asia-Pacific region is highest and has been increasing rapidly from $50M to $910M in recent years. These tend to propel the market growth of UV LEDs using Silicon Carbide and Gallium Nitride materials in forecast period as freshwater demand will always be high. Asia-Pacific is closely followed by North America in the UV LED Market growth due to presence of major market players in this region which provides technology upgrades in UV LEDs.
UV LED Market Drivers
Rise in Environmental concerns drives market growth
With the rising Environmental concerns at global level, the adoption of UV LEDS for various applications in different industries tend to drive its market growth. LED’s have been increasingly used in applications where UV lamps (mercury, xenon, amalgam, excimer) have operated for decades. Improvements in UV-LED flux density, stability and life hours have made UV LEDs a viable solution for replacing traditional UV light sources such as mercury arc lamps, arch lamps, hot and cold cathode lamps and grid lamps. With the rising Environmental concerns, the adoption of UV LEDs came into play. UV LEDs are more environment friendly as they do not contain harmful mercury, they do not produce ozone and consume less energy as well. These major advantages uplift the demand of UV LEDs which is expected to propel its market growth in forecast period. UV-C LEDs is rapidly growing in applications such as germicidal (UVGI) for air, surface and water purification. UV LED curing provides solutions to the negative environmental impact as it offers improved flux density, stability and long-life hours which makes UV LEDs a viable solution for replacing traditional UV light sources such as mercury arc lamps, arch lamps, hot and cold cathode lamps and grid lamps which drives its market growth in the forecast period.
UV LEDs offers compactness and long durability
UV LEDs do not contain toxic mercury and are often found in CCFL technology. They are much smaller and more durable than CCFLs and are more resistant to vibration and impact, resulting in less product breakage and reduced waste and maintenance expense as well.
