Osram Unveils Five New Colour Versions For LED Duris P 5
The company has revealed new design options with indium gallium nitride and indium gallium aluminium phosphide mid-power LEDs
Osram Opto Semiconductors now offers the mid-power LED Duris P 5 in colour.
The five new versions have impressively high luminous efficacy from a compact form factor, already known from the white version. The LEDs are ideal for architecture lighting and for the hospitality sector, in other words hotels and restaurants.
The five colour versions of Duris P 5 are “deep blue" (450 nm), “blue" (470 nm), “true green" (528 nm), “yellow" (590 nm) and “red" (615 to 625 nm).
At the heart of the different colours are state-of-the-art chip technologies from Osram, based on either the InGaN material system or InGaAlP depending on the wavelength.

Low forward voltages and optimised light extraction result in high luminous efficacies for all types. The “deep blue" version, for example, delivers a light output of 140 mW (at 100 mA and 250C), corresponding to a typical efficiency of 48 percent. Efficiency is defined as the ratio of the amount of light produced to the amount of power consumed.
As members of the mid-power class, the colour versions of Duris P 5 are ideal for linear, area or omnidirectional lighting applications in which the light has to be distributed as uniformly as possible.
Colour mixing is also much easier in applications involving several colours.
More design options for professional lighting “The colour Duris P 5 versions will give our customers even greater freedom in designing luminaires. A good example is the combination of white and coloured mid-power LEDs within a luminaire", says Martin Wittmann, Product Manager Marketing SSL at Osram Opto Semiconductors, and adds, “The use of the Duris power class also reduces system costs while at the same time improving the distribution of light and simplifying thermal management."
Like the white versions in the P 5 family, the coloured Duris versions are capable of withstanding extremely harsh conditions. The innovative package technology offers greater corrosion stability compared to conventional mid-power LEDs. The component dimensions measure just 2.6 by 2.2 mm also allow good optical control in connection with secondary optics.
In addition to architectural lighting and signage applications, the new Duris colour versions can be used in LED lamp and luminaire modules with “remote phosphor" technology. In this case, the converters needed to generate white light are not attached directly to the chip but are illuminated by “deep blue" LED from a certain distance, causing them to luminesce.
This remote phosphor technology results in uniform distribution of light and high luminous efficacy.
The colour Duris P 5 versions will be premiered at the Osram booth #1001 at Lightfair 2013 taking place in Philadelphia between April 23rd and 25th, 2013.

AngelTech Live III: Join us on 12 April 2021!
AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!
Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.
2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.
We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.
We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.
Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.
Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.
So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
