Stanley Electric developed an ultraviolet LED using a glass package and demonstrated it on "CEATEC JAPAN2010". Since an inorganic material is used as the encapsulating material, performance deterioration due to ultraviolet rays is small, and the life of the module is prolonged as compared with the case of using a resin material. Stanley Electric hopes to exploit the use of LEDs in harsh environments (such as high temperatures and humidity). The appearance is to install an ultraviolet LED chip on the filament portion of the bulb, and then add the shape of the glass cover. According to Stanley Electric, the inside of the glass cover, that is, the ultraviolet LED chip is in a vacuum state. The emission wavelength was 375 nm. The forward current is 20 mA and the forward voltage is 3.3V. The optical output power is 6mW. According to Stanley Electric, although it is still in the development stage, it has been introduced to customers. At the time of the demonstration, in addition to the prototypes on which the UV LED chips were mounted, prototypes for mounting red, green and blue LED chips were also exhibited.
