Exploring the World of L.E.D. UV Lamps: Applications, Growth, and Market Potential

Introduction to UV Lamps and Their Benefits

UV lamps have become increasingly important tools in various industries, particularly in the fields of sterilization, disinfection, and purification. With the advancement of technology, there has been a surge in the development of LED UV lamps, which offer a more efficient and convenient method for maintaining clean and hygienic environments.

Understanding UV Rays and Their Applications

UV rays are divided into three categories: UV-A, UV-B, and UV-C. Each has distinct applications and benefits:

UV-A: Primarily used in money detectors, commercial lighting for making clothes whiter, and air purifiers based on photocatalyst technology. Higher-power products such as light curing, metal coating, wood coating, lithography, and exposure machines require UV-A in different wave bands of over 1 watt, making it a crucial component in numerous industries. UV-B: Utilized for light therapy, plant growth, and food preservation. However, its application range is more limited compared to the other two types. UV-C: Widely used for sterilization and purification in everyday life, ranging from surface sterilization of items like mobile phones, toothbrushes, and vacuum cleaners, to air, food, and water purification.

Market Growth and Future Trends of LED UV Lamps

The global market for UV LEDs, particularly in UV-C, is experiencing significant growth. The UV LED market was valued at US$233 million in 2017 and is expected to reach US$1.224 billion by 2022, demonstrating a compound annual growth rate (CAGR) of 33%.

Among the various types of UV LEDs, the growth of UV-C LEDs stands out, with a CAGR of approximately 74%. This surge in popularity is due to its wide range of applications in sterilization, disinfection, and purification processes. The market share of UV-C LEDs in 2017 was only 14%, but it is projected to reach 73% by 2022.

The application of UV-C LEDs is becoming more integrated into everyday devices and settings. For instance, UV-C LEDs are being used to eliminate allergens and protect consumer products, including baby products, daily-use items, and high-contact surfaces like mobile phones and toothbrushes. Additionally, some lighting manufacturers are beginning to incorporate UV-C LEDs into general lighting fixtures, enhancing their product offerings and appeal.

Power Levels and Market Dynamics

The power levels of UV-C LEDs are categorized into three ranges: under 5mW, 5-10mW, and 10-30mW. Currently, products in the 3-5mW range dominate the market. However, as technology advances, manufacturers are focusing on producing higher-power LEDs, with the 5-10mW range expected to become the primary sales driver in 2019. Higher-power products, such as those reaching 10-30mW, are gaining traction as well.

Key Players in the Market

In 2016, the UV-A market was dominated by Nichia, Nitride Semiconductors, and Seoul Viosys. By 2017, South Korean manufacturers emerged as leaders in both UV-A and UV-C markets, with Seoul Viosys, LG Innotek, and Nitride Semiconductors at the forefront.

Currently, LG Innotek is a major player in the UV-C market, with products capable of reaching 100mW. They are also preparing to launch 150mW products soon. Seoul Viosys is another active participant, continuously introducing new packaging techniques and launching finished products. Other LED manufacturers, such as Jingdian Lunda and Sanan, have recently launched UV-C LED products with wavelengths from 275 to 285nm, while Yanjing offers 265nm UV-C products. Nichia is also planning to introduce 280nm UV-C LEDs. These manufacturers are expanding their presence in the European and American markets as well.

Market Potential and Challenges

While the market for UV-C LEDs is booming, it faces challenges in the consumer market due to the risk of falling prices and market acceptance. Key factors influencing the market potential include:

Consumer recognition and understanding of the UV sterilization benefits of these products. The need for fast and convenient sterilization effects. The current price-performance ratio of UV-C products.

Overcoming these challenges will be crucial for the continued growth and acceptance of UV-C LEDs in the consumer market.
