Advanced Power TopLED Plus optimized LED

Osram Opto Semiconductors has released the Advanced Power TopLED Plus optimized LED designed particularly for architectural and sales lighting. It combines impressive brightness with high luminous efficacy of up to 90lm/W and comes in a robust package. The device is tailored for applications that call for bright light but offer very small space, such a highlighting edges and contours or for illuminating surfaces in a uniform light.

The new Advanced Power TopLED Plus has a luminous flux of up to 27lm (100mA /5700K). Not only is it on average 15 percent brighter than the standard version it is also available in different white tones from 2700- to 6500K. This means that different white light colors from warm white to cold white can be achieved and all the requirements from linear lighting applications to strip lighting and surface illumination can be met. The LED is well-suited for illuminating the facades and outlines of buildings, and is suitable for applications in retail outlets, such as freezer cases. The device combines remarkable brightness with low power consumption and small dimensions.

The small high-intensity LED has a typical beam angle of 140 and a homogenous white color from every viewing angle. Its small dimensions enable light to be mixed in the smallest of spaces. A large number of small LEDs produce a more homogenous light on a surface than a few large LEDs. Designers are therefore free to create new lighting solutions, limited only by their imagination.

In addition, the Advanced Power TopLED Plus is specified for a connected load of up to 0.5W. Heat is efficiently dissipated via gull-wing connections to the lead frame and the pc board, so there is no need for expensive thermal management. From this summer, the LED will be the latest addition to Osram's extensive LED portfolio which includes LEDs with outputs from 0.25- to 18W.
