SemiLEDs launches low-voltage LEDs for battery-powered mobile appliances

SemiLEDs Corp of Boise, ID, USA, which manufactures high-brightness LEDs at its plant in Hsinchu Science Park, Taiwan, has launched its new-generation, high-brightness, low-voltage LEDs designed for battery-powered mobile applications.

The new GaN-based LEDs are available in blue and green colors and feature extremely low operation voltage, normally below 3V for standard current density, resulting in much longer battery life for mobile appliance applications such as flash for cameras, back-lighting for notebook computer, and small cell-phone and PDA screens.

In SemiLEDs’ unique design of Mvp LED on a metal alloy base, the lower voltage was achieved by a combination of proprietary technologies including careful design of the epitaxial structure and the current path in its vertical LED chip configuration.

Available in a wide range of chip sizes, SemiLEDs says that its new LEDs will significantly prolong battery life for mobile appliances and simplify LED driver circuitry, especially for cell-phone flash, resulting in cost saving. The firm says that the chips have already been introduced in mega-pixel camera flashes for the latest models of cell phones offered by what it describes as one of the top manufacturers.
