UVC LED market outlook

发布时间：2021-08-26 16:40 来源：萤光创新

In recent years, due to the impact of the epidemic, people have a lot of understanding of UVC LED, UVC LED refers to the 220-280nm band, also known as deep ULTRAVIOLET LED, due to small size, long life, fast opening speed, low power consumption, thorough sterilization and other characteristics, first used in the UV sterilization market, and because it does not contain mercury and other toxic substances, UV mercury lamps have been gradually replaced, opening the health sterilization market.

Deep uv applications are widely marketed

The compact size of the DEEP Uv LED makes it easy to install in most applications, such as:

Water sterilization: humidifier, commercial water dispenser, pipeline machine, ice machine, intelligent toilet, etc

Air sterilization: air conditioning hang-up, air conditioning cabinet, car air conditioning, air purifier, heater, etc

Surface sterilization: intelligent garbage can, food crisper, milk bottle sterilizer, refrigerator, vacuum cleaner, etc

Through these applications, it can be seen that the use of ultraviolet sterilization is very wide, so it shows great application value and potential.

How to choose a DEEP UV LED?

The choice of deep ULTRAVIOLET LED mainly lies in: the choice of light power, wavelength, life, different application scenarios will have different solutions to choose from, Qingdao Fluorescent Innovation is a professional team formed by postdoctoral fellows, can provide more targeted solutions according to specific requirements.

1 - light power

Current common deep ULTRAVIOLET LED light power 2 mW-100 mW. In the selection according to the appropriate use of the environment, sterilization effect and sterilization time as the selection of parameters. According to partial test data, a 3 mW UVC-LED with a 60° light outlet Angle can kill 99.99% of E. coli on the surface within 10 seconds at a distance of 2 cm.

Some products can choose sterilization module based on deep ULTRAVIOLET LED, relatively beautiful appearance, convenient installation, technology is more mature, mostly used for humidifier, ice machine, water tank antibacterial, intelligent toilet and other sterilization scenes.

2- Peak wavelength

When selecting the peak wavelength of UVC-LED, the following technical points need to be understood:

1. The most suitable wavelength for sterilization is 265 nm, so most sterilization wavelengths are between 240 and 280nm, which can ensure good sterilization effect of UVC LED.

2, the sterilization effect of UVC LED also depends on the peak wavelength and light power

3 - life

Deep ULTRAVIOLET leds live in the 2,000 to 15,000 hour range, but long LIFE is not the best option. For UVCLED life, what's right is the best.

Identifying the actual requirements for life span of application scenarios can help reduce solution costs and bring more market opportunities. After careful analysis of product requirements, we find:

Humidifier: 0.8 hours/day *30 days/month *8 months/year *3 years =576 hours;

Straight water dispenser: 20 min/day *30 days/month *12 months/year *5 years =600 hours;

Water tank: 1 hour/day *30 days/month *12 months/year *3 years =1080 hours;

Air conditioning: 2 hours/day *30 days/month *6 months/year *5 years =1800 hours;

Air purifier: 5 hours/day *30 days/month *12 months/year *3 years =5400 hours.

You will find the most appropriate solution to maximize product advantages through the use time of the product.

4 - the light Angle

The material characteristics of DEEP ULTRAVIOLET LEDS lead to a higher proportion of horizontal light output than vertical light output. Common light Angle: 7°, 45°, 60°, 120° and so on. In fact, no matter how large the light Angle of the UVC LED you choose, you can cover the sterilization space you need by the number of beads. Especially for the sterilization range is not sensitive to the scene, small light Angle can make the light more concentrated, so that the sterilization time is shorter.

Qingdao Fluorescent Innovation Technology Co., LTD., with a professional postdoctoral team, focuses on the research of ultraviolet sterilization application. After years of deep cultivation of ultraviolet industry, the company has obtained a number of national invention and utility model patents. At present, a number of sterilization module products have been put into the market.
