Lumileds Introduces New Luxeon Module

Multicolour Module 2.5W produces high flux and exact colour points in architectural and general outdoor lighting

Lumileds has introduced the Luxeon Multicolour Module 2.5W, a compact RGBW module that is described as producing high flux and achieves exact colour points in architectural and general outdoor lighting applications.

The 4-in-1 module simplifies system design by combining red, green, blue and white emitters in a compact 5050 footprint, PLCC package. “We designed a barrier between the colour and white emitter to eliminate the problem of crosstalk, allowing designers to consistently achieve the exact colour point they are targeting,” said Jennifer Holland, product line director at Lumileds. Crosstalk can occur when a direct LED excites the phosphor in a neighbouring white LED, altering the emitted colour.

Typical flux of the module 2.5W is 18 lm (red), 38 lm (green), 15 lm (blue) and 53 lm (white) at 120mA. The emitter may be driven at up to 240mA to achieve breakthrough lumen output. The single emitter approach enables seamless colour mixing without the shadowing associated with combining emitters of differing heights. The module especially shines in space-constrained applications, including linear architectural designs where four emitters require double the footprint of a single emitter.

The colours in the Luxeon MultiColour Module 2.5W can be individually or separately controlled for maximum flexibility in lighting design. An additional convenience of the module's 5050-footprint is compatibility with industry optics to achieve different beam angles and intensities. Applications include outdoor facade lighting, architectural lighting, signage and any indoor applications with aggressive environments, from industrial plants to swimming pools.



AngelTech Live III: Watch the virtual event ON-DEMAND!

AngelTech Live III was broadcast live on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and features online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

The event covered the whole spectrum of key developments affecting the compound semiconductor industry. 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. This was considered a roadmap for this device, along with technologies for boosting its output.

With 3 interactive sessions over 1 day AngelTech Live III proved 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.
