Next generation UV LED advantage is expected to increase by 31% over the next 5 years

Although in the daily life of ultraviolet with potential danger to life, such as sunburn, but UV will provide many beneficial effects in many fields. Like standard visible LED, the development of ultraviolet LED will bring more convenience to many different applications.

The development of latest technology is part of the market ultraviolet LED expanded to new product innovation and high performance. Design engineers are noticing that the new technology of UV LED can generate huge profits, energy and space savings compared to other alternative technologies. The next generation of UV LED technology has five important advantages, which is the technology market is expected to grow by 31% in the next 5 years.

Use widely

UV spectrum contains all the length of 100nm to 400nm wavelength, generally divided into three types: UV-A (315-400 nm, also known as UVA), UV-B (280-315 nm, also known as UVB), UV-C (100-280 nm, also known as ultraviolet).

Dental treatment instrument and distinguishing use is application of ultraviolet LED early, but extend the performance, cost and durability benefits and the life of the product, is to use ultraviolet LED increased rapidly. The use of ultraviolet LED current includes: optical sensors and instruments (230-400nm), UV authentication, bar code (230-280nm), surface water sterilization (240-280nm), differential and humoral detection and analysis (250-405nm), protein analysis and drug discovery (270-300nm) medicine, light therapy (300-320nm), and polymer (printing ink 300-365nm), (375-395nm), surface sterilization discrimination / Beauty sterilization (390-410nm).

Environmental impact - lower energy consumption, reduce waste and hazardous materials

Compared to other alternative technology, ultraviolet LED has obvious environmental benefits. Compared with fluorescent (CCFL) lamps, UV LED energy consumption is low 70%. addition, UV LED through the ROHS certification, excluding CCFL technology common harmful substances mercury.

UV LED is smaller in size and durable than CCFL. Because of the effect of anti vibration and shock resistance of UV LED, there is little breakage, thus reducing the cost of waste and cost.

Increase life

In the past ten years, LED has been the life of ultraviolet challenges. Although it has a lot of benefits, but the use of UV LED decreased significantly, this is because the ultraviolet beam is easy to break down the LED epoxy resin, which will reduce the life of UV LED to less than 5 thousand hours.

Ultraviolet LED next generation technology in "hardening" or "UV" epoxy package features, despite the offer of life will reach 10 thousand hours, but still far can not meet the application most.

In the past few months, the new technology to solve the engineering challenges. For example, the use of a glass lens with a TO-46 package to replace the epoxy resin lens, so that the use of time to extend at least ten times, up to 50 thousand hours. With the challenge of this major engineering challenge and the absolute stability of a certain wavelength, the LED technology has become an attractive option for the growing use of.

The next major challenge UV LED technology efficiency. For many applications with wavelength less than 365nm, such as medicine, light therapy, water disinfection and polymer treatment, output power of ultraviolet LED was only 5%-8%. when the input power is above 385nm and the wavelength of ultraviolet, improve the efficiency of LED, but only the input power of 15%. with the technology to solve the efficiency problem constantly. More applications will begin using ultraviolet LED technology.

Performance

Compared to other alternative technology, ultraviolet LED also has obvious performance advantages. UV LED can provide a smaller beam angle and a uniform beam. Due to the low efficiency of UV LED, most design engineers are looking for a beam angle that maximizes the output power in a target area. For ordinary UV lamps, engineers must rely on the use of enough light to illuminate the area in order to obtain uniformity and compactness. For UV LED, the lens takes into account a more compact radiation angle, so that most of the output power of UV LED is in place.

To match the performance of alternative technology will require the use of other lens, thus increasing the additional cost and space requirements. Due to ultraviolet LED without other lens can get compact beam angle and uniform beam, has lower energy consumption and increased durability, so compared with CCFL technology, use LED less than half the cost of ultraviolet.

Special selection of cost-effective

For a specific application of UV LED scheme or using standard techniques from the two aspects of cost and performance, the former often more practical. LED is used in many cases in the array, while the entire array of beam and beam intensity is essential. If there is a supplier to provide application specific needs of the whole integrated array, bill of material price will reduce the number of suppliers will be reduced, and prior to the design engineer at delivery, can also be tested on the array. In this way, the reduction in the number of transactions can save the cost of engineering and procurement, and provide efficient solutions to meet the requirements of terminal applications.

To ensure suppliers can be found
