Miniature white LEDs

Toshiba Electronics Europe (TEE) has introduced three high-brightness, miniature white LEDs that will allow designers to deliver high-efficiency solid-state solutions for a range of commercial, residential and industrial lighting. With a drive current of 350mA, the new TL12W03-D white, TL12W03-L warm white and TL12W03-N neutral white LEDs deliver high typical luminous flux ratings of 90 lumens, 75 lumens and 100 lumens, respectively. The new LEDs are supplied in miniature surface mount packages with dimensions of 10.5x5x2.1mm. All of the devices will operate at temperatures between -40 and 100ºC, making them suitable for both indoor and outdoor lighting applications. These LEDs package technology has been designed to ensure a low thermal resistance. This ensures improved heat dissipation characteristics, which simplifies thermal management in the target lighting design. All of the new LEDs are rated for a maximum forward current of 500mA and a typical forward voltage at 350mA of 3.3V. Maximum power dissipation for the LEDs is rated at 1.95W.
