Segment blue LEDs
17 December, 2003Rohm has available a series of blue LEDs for applications such as industrial equipment, test and measuring machines and ticket and vending machines to name a few.
Development breakthrough for UV LEDs
21 November, 2003Researchers at Sandia National Laboratories developing ultraviolet (UV) light-emitting diodes (LEDs) recently demonstrated two deep UV semiconductor optical devices that set records for wavelength/power output. One emits at a wavelength of 290 nm and produces 1.3 milliwatts of output power, and the other emits at a wavelength of 275 nm and produces 0.4 milliwatts of power.
