LG Innotek Unveils the World’s First ‘100mW’ UV-C LED

 
LG Innotek today announced that the company has developed the world’s first 100mW (mill watts) UV-C LED. This development is 2 years ahead of the industry forecast that predicted its development would be successful by 2020.

UV-C LED is a product that emits ultraviolet light with short wavelengths ranging between 200 – 280 nanometers (nm), and is also called Deep UV. It is used in sterilizing and hardening devices with its ability to destroy bacterial DNA and cause chemical reactions with special materials. LG Innotek’s product emits UV in the range of 278nm.

UV-C LED can produce more powerful sterilizing effects with higher light output, but it is very difficult to obtain a stable quality in products with it due to heat. The companies that have led the market have also planned to launch the 100mW UV-C LED by 2020.

LG Innotek has overcome the technological limit by applying the epitaxial structure and the vertical chip technology that maximize light extraction. The ultraviolet output is raised and the heat is discharged effectively, ensuring stable quality reliability. This one 100mW UV-C LED can emit strong sterilization ultraviolet light for more than 10,000 hours.

With this development of the product having a light output of 100mW, LG Innotek has now become capable of expanding its UV-C LED application field. As the product can rapidly sterilize flowing water and even air, it can be used in a wide array of household appliances from water purifiers and air purifiers to air conditioning systems for buildings and automobiles as well as water treatment devices.
 
Conventional UV-C LEDs with a light output level of 1~2mW are mostly used for portable sterilizers or small household appliances. Due to their weak UV-C power, their scope of application is limited.

As the company has discussed development of a variety of products using UV-C LED with a number of other global companies and the demand for high-output LEDs continues to grow, it is expected that the demand for 100mW UV-C LEDs will also increase rapidly.

LG Innotek intends to accelerate its securing of the UV LED market leadership. In particular, the company has confidence in hitting the market with its unrivaled technology in the UV-C field that can offer excellent sterilization and curing performance.

The company’s quality competitiveness has been proven by its launching of innovative products such as the LED module for sterilizing water purifier faucet aerator and the UV LED sterilizer for escalator handrails one step ahead of its rivaling Japanese companies.

A representative of LG Innotek said, “We will continue to widen the technological gap with our competitors and introduce innovative products that our customers desire to stay as the leader of the market.”

Future-proof road lighting

11/27/2017 | Trade Press

With Streetlight 11 Osram offers a future-proof platform for smart city applications

Today's towns and cities have a particular responsibility, and search for solutions for reducing their ecological footprint and organising their public spaces in safer and more intelligent ways. Specifically, this concerns intelligent traffic guidance, parking space management, safety monitoring and new supply models for electrical mobility. Networked lighting infrastructures are found in the centre of such processes. With its Streetlight 11 range of road luminaires, Osram Lighting Solutions offers a future-proof, technological platform for the diverse elements of a smart city.

The new, efficient Streetlight 11 is an open and upgradable system that expands with its tasks - just as cities of the future will do. Customers can decide to either already select an individual smart city solution or else select luminaires that can be upgraded at any time. Once a network is established with the new road luminaires, customer-specific requirements that then change can be implemented.
The modular luminaire concept of Streetlight 11 enables control and monitoring systems to be integrated based on powerline technology or via radio frequency (RF). The luminaires are available as standard as Smart City luminaires (with Powerline or RF) or as Smart City ready versions. Thanks to the integrated mechanical interface, simple retrofitting of sensors and data- or camera systems is also possible on-site, enabling e.g. parking space management, safety monitoring and traffic control. The components are supplied with power directly from the luminaire. Customers benefit from a reliable system solution, i.e. Osram offers luminaires, controllers, sensors, software and accessories from a single source.
Streetlight 11 scores with outstanding, homogenous lighting to increase levels of safety in the public space. It simultaneously contributes actively to protecting nature and the environment – energy consumption can be cut by up to 80% and light pollution is avoided due to precise light alignment, whilst brightening of the night sky and the attraction of nocturnally active insects is reduced to a minimum. The range of luminaires offers a diversity of options for selection and combination for illuminating roads, paths and squares: three construction sizes for mounting heights of 3 to 12 metres, two colour temperatures, individually settable luminous flux levels and diverse control possibilities.
 

OSRAM with headquarters in Munich, Germany is a globally leading high-tech company with a history spanning more than 110 years. Primarily semiconductor-based products enable a wide diversity of applications ranging from virtual reality to autonomous driving and from smartphones to networked, intelligent lighting solutions in buildings and cities. OSRAM utilises the infinite possibilities of light to improve the lives of people and societies. With OSRAM innovations we will not only see better in the future but also communicate, travel, work and live better. OSRAM had approximately 26,400 employees worldwide with turnover exceeding 4.1 billion euros to the end of fiscal year 2017 (30 September). The company is listed on the Frankfurt am Main and Munich stock exchanges under WKN: LED 400 (stock exchange symbol: OSR). Further information can be found in the internet at www.osram.com.
