Energizinig with Light
Providing new value through light
Light not only illuminates darkness but can also be utilized to offer new effects by harnessing its energy. Stanley Electric will efficiently leverage the energy of light, such as in deep ultraviolet light water sterilization applications, and provide new value across various fields.
Deep ultraviolet LEDs for water sterilization attracting attention
As the world's population increases, securing safe, clean water has become a matter of urgency. Water purification has conventionally been done with filters or chlorine, but these methods have not been effective against chlorine-resistant bacteria and microorganisms (such as Cryptosporidium). Under these circumstances, water sterilization that uses deep ultraviolet LEDs, which are highly effective against resistant bacteria, is attracting attention. Stanley has developed high-power deep-ultraviolet LEDs with a high sterilization capacity. This product is available as an alternative light source to replace mercury lamps, which have been the mainstream light source used in ultraviolet light application devices, such as sterilization devices.

Conditions for UV-C LED disinfection effect test (Bacterial strain: E.Coli / Output: 40 mW/ Irradiation distance: 100 mm / Irradiation time: 120 seconds)
Aluminum nitride substrate and photonic structure enables high power
Stanley Electric achieved the world's highest light output level of 200 mW at a wavelength of 265 nm, which has the most powerful sterilization capability. An aluminum nitride substrate with a photonic structure behind the substrate helps realize light output of 200 mW, the highest level in the world. Its compact size compared with existing sterilization light sources allows greater freedom of device design, making it possible to roll out deep ultraviolet LEDs for new applications as a mercury-free, environmentally friendly light source.
Deep UV Water Sterilization LED Reactor
Major improvements in sterilization performance through proprietary water rectification mechanism and light distribution technology
The combination of our proprietary water rectification mechanism and our light distribution technologies cultivated in the manufacture of automobile headlamps has made it possible to irradiate water effectively with deep UV light. Compared with existing lamps, this product has many benefits. It is mercury free and places less burden on the environment, it can be used for long periods even with repeated switching on and off, and it obtains power instantly without needing to be warmed up. The number of applications for this product is likely to expand going forward.
Contribution to Sustainable Food with Light
Delicious fish on the dining table. In order to preserve the limited marine resources for the future, fish farming and related research are advancing in Japan.
Stanley Electric have been working to contribute to sustainable food through the power of light, applying our own technology to provide innovative solutions. Among the various efforts made by companies, we have recently gained attention for its involvement in collaborative research on "light aquaculture technology using LEDs."
Experiments where green LED lights were directed at fish have shown that the growth of flatfish, such as the flounder, is accelerated, and practical use of this technology has already begun.
"Light aquaculture," which enhances the growth rate of farmed fish such as flounder and turbot, has been a focus of research. we have participated in collaborative research with the Kanagawa Prefectural Fisheries Technology Center and Kitasato University. It was demonstrated that by illuminating juvenile fish with green LED light during rearing, the average weight increased 1.6 times faster compared to conventional rearing methods. As a result, the time to market was reduced by about three months.
This reduction in time to market contributes to a significant reduction in costs. As for the taste, flounder raised under fish farming lighting has been well received and is said to be "just as delicious as conventional products."
