German Institute showcases the latest UV LEDs
Ferdinand-Braun-Institut (FBH) and its subsidiary UVphotonics NT will be held in Berlin from April 22nd to 25th, "2018 UV LED Technology and Applications International" The conference will showcase its latest UV LEDs.
They discovered a degradation mechanism during the development process: during the first few hours of operation, electromigration of hydrogen in the UV-B LED structure occurs, which is accompanied by a drop in the optical power of the device.
After the corresponding design adjustments, UV-B LEDs with an L50 life of 8,000 hours can be produced. The optimization of the device has further improved the reliability of the LED, and the life of the L50 is expected to be significantly extended. In addition, the output power at 350 mA can be increased to 30 mW.
The UV-LED illumination system shown in the figure has three different wavelengths. Their brightness and intensity can be individually adjusted to determine optimal illumination for a diverse plant secondary metabolite.
At the conference, FBH scientists will also showcase a compact diode laser source for the deep ultraviolet spectral range with an emission wavelength of 222 nm, which is difficult to achieve in this area. The device converts the light of a gallium nitride-based high power diode laser into a UV spectral range by frequency doubling (single pass) and is likely to be miniaturized. Wavelength-stable narrow-band sources are particularly suitable for spectroscopy applications such as absorption spectroscopy and Raman spectroscopy for medical diagnostics and material analysis.
Mu Linsen subsidiary received 50 million
Recently, Mulinsen (hereinafter referred to as "the company") announced that the company's wholly-owned subsidiary Yiwu Mulinsen Lighting Technology Co., Ltd. (hereinafter referred to as "Yiwu Mulinsen") received the Yiwu Information Optoelectronics High-tech Industrial Park Management Committee on April 13, 2018. The "Notice on Disbursement of Yiwu Mulinsen Lighting Technology Co., Ltd. Investment and Construction Subsidy" (Yi Gaoxin [2018] No. 28) agreed to allocate RMB 50 million for the investment and construction subsidy of Yiwu Mulinsen Lighting Technology Co., Ltd.
According to the announcement, the above funds were transferred to the Yiwu Mulinsen Company account on April 13, 2018, which is a government subsidy related to income, which is recognized as current income upon receipt. The government subsidies obtained by the company this time are not used for purchase or construction or other forms of long-term assets, so it is a government subsidy related to income.
Mulinsen said that the government subsidies received this time are expected to increase the company's total profit for the year by RMB 50 million.
