LED with 1000 lumens

Osram has developed a small light-emitting diode spotlight that achieves an output of more than 1000 lm for the first time. That's brighter than a 50 W halogen lamp, making the device suitable for a broad range of general lighting applications.

The Ostar Lighting LED can provide sufficient light for a desk from a height of 2 m. Its small size also enables the creation of completely new lamp shapes.

To achieve the 1000 lm output for the tiny LED, the experts at Siemens' Osram subsidiary employed a system for high chip-packing density, whereby the researchers managed to integrate six high-performance LED lighting chips into the unit's small housing. Each chip has an area of only 1 square mm, which makes for very concentrated overall luminosity.

Different types of LEDs are used in various areas, for example as background lighting in mobile phone displays, as well as in car turn-signal lights, brake lights, and daytime running lights. The diodes are extremely small and consume little energy because they efficiently convert electricity into light. The Ostar Lighting LED, for example, produces 75 lm per W at 350 milliamperes of operating current " much more than an incandescent lamp, which only converts a fraction of the energy supplied into light with the rest list as heat energy.

In addition, LEDs contain no lead or mercury, which makes them very environmentally friendly. They also last around 10 times longer than halogen lamps and 50 times longer than incandescent lamps, thereby helping to significantly reduce maintenance costs.

For many years, however, LEDs were unsuitable for room lighting applications because they weren't bright enough. The Ostar Lighting LED marks a further step towards suitability for such applications.
