New LEDs Bring Brighter Glow To Electronic Products

New ultraviolet blue and green LEDs have been developed that are said to offer significantly improved performance over existing devices. Based on InGaN materials with a SiC substrate, the UV LEDs (left photo) boast of high power output, long life span, shock and vibration resistance, and a -40°C to 85°C temperature range. Among the many uses of the lamps are medical systems, vending machines, and battery-operated test and detection devices. Another family, the X-brite LEDs (right photo) claim a 20% higher brightness than competitive devices. Blue X-brights have an intensity of 3,500 mcd, while the green offer up to 14,000 mcd. These come in through-hole and SMT styles. KINGBRIGHT CORP., City of Industry, CA. (909) 468-0500.
