RGB MultiLED in new attire:

With two to three times the output and five times the life span, the new 6-lead MultiLEDs from Osram Opto Semiconductors leave their predecessors firmly in the shade. All three chips (red, green and blue) are fabricated using thin-film technology and allow almost all the light to be emitted at the surface. This results in high optical efficiency and new applications, such as advertising and effect lighting.
The new generation of 6-lead MultiLEDs strengthens the RGB LED family of Osram Opto Semiconductors at the top end. For the first time, thin-film chips are being used for all three colours. They emit almost all of their light at the top, so they achieve high luminous intensity. Thanks to the 6-lead design, each chip can be individually controlled. By additive colour mixing it is therefore possible to create all the colours in the colour triangle, including white. What’s more, this design enables heat to be efficiently removed and the LEDs to be connected in series. The optical efficiency of the brightest generation of chips of this size is 43 lm/ W for red, 36 lm/ W for green and 11 lm/ W for blue. Special silicone encapsulation protects the LEDs against premature ageing due to short-wave light and ensures that the LEDs last five times longer than their predecessors. Depending on the operating conditions, a life span, of more than 50,000 hours can be achieved.
The much brighter MultiLEDs of the new generation can be used for backlighting displays and for general lighting. They are also being used for more and more outdoor applications, for example for illuminating building facades and advertising sites. And they have already become established as light sources in stage productions. These high-intensity LEDs are suitable for full-colour video displays and provide high-contrast pictures even on huge screens as used in sports stadiums. The diffused silicone encapsulation and a black surface of the package improve contrast by about ten percent.

The new generation of 6-lead MultiLEDs with black surfaces is much more powerful than the previous generation and lasts five time longer.
