Explain the four major advantages of UV LED technology

Everything has a two-sided nature, and ultraviolet (uv) is also proportionate. Although ultraviolet radiation has certain harm to people, such as sunburn, skin cancer, etc., ultraviolet rays provide beneficial effects in various fields. The latest high-tech technological development is to expand the market of UV LED to a new height of product innovation and performance. Compared with other traditional technologies, UV LED technology can bring huge economic benefits, provide more energy and save space. UV LED technology has four important advantages:

First, widely used

The current uses of UV LEDs include: optical sensors and instruments, UV authentication, barcodes, surface area water sterilization, identification and body fluid detection and analysis, protein analysis and drug discovery, medical light therapy, polymer and ink printing, identification of authenticity, Surface sterilization / beauty sterilization, glue curing and so on.

Second, longer life

In the past decade, UV LEDs have been challenged by their lifetime. Although it has many advantages, UV LED's photoelectric conversion efficiency is very low and its reliability is not good. The main reason is that the previous UV LED packaging process uses organic materials for encapsulation, and long-term UV ultraviolet rays can also damage And accelerate the aging of the organic materials used in the package, so that the previous UVLED can not be recognized by the market.

Today, several major foreign manufacturers have invested huge funds to develop new packaging processes, making the overall performance of UVLEDs in recent years a big step, at least in the use of UVA band is basically stable. In recent years, some domestic manufacturers are also working hard to develop high-performance chips and packaging processes.

Third, more efficient

UV LEDs are used in arrays in many cases, and the uniformity of the beam pattern and light intensity is critical throughout the array. This is the issue of the homogeneity of light spot we are talking about. From whlx's point of view, how to enable customers to realize mass production, how to make the customer's defective rate lower, and how to make the customer's production efficiency faster, all need to be considered. Although many UVLED solution providers will also arrange the lamp beads, but few people will pay attention to whether the light source has the customer's relationship with the production capacity, yield problems. Based on the experience of 10 years of service in the industry, whlx integrates the optical system, cooling system, and control system to meet the needs of customers, making the performance of the complete set of light source more temperature-efficient. The customer's production efficiency is higher and the resulting defective rate is reduced.

Fourth, lower energy consumption, waste reduction and non-hazardous materials

Compared to other traditional technologies, UV LEDs have significant environmental benefits. Compared to fluorescent (CCFL) lamps, UV LEDs consume 70% less energy. In addition, UV LEDs are ROHS certified and do not contain mercury, a common hazardous substance in CCFL technology. Ultraviolet LEDs are smaller in size and more durable than CCFLs. Due to the fact that UV LEDs are vibration- and shock-resistant, damage rarely occurs, reducing waste and costs.
