Cree Shrinks Its SiC Based XLamp XQ LEDs

The firm says its silicon carbide based devices offer compactness and superior light distribution
Cree is marketing its new product family, the XLamp XQ LEDs.

These compact modules offer novel light distribution and high reliability, enabling broader light distribution such as those used in omni-directional lamps and fixtures.

The XQ LEDs are Cree’s smallest lighting-class LEDs measuring just 1.6mm x 1.6mm. This is 57 percent smaller than Cree’s XLamp XB package.

Built on Cree’s SiC-based SC3 technology platform, the ceramic-based XQ LEDs are designed to deliver the long-term calculated lifetimes of Cree’s other high-power LEDs, such as the XP or XT LEDs.

The difference with the XQ LEDs is that a new light emitting pattern directs more light towards the edge rather than the centre of the package.

Cree says that compared to existing LEDs, XQ LEDs allow fewer packages to achieve a wide, distributed light pattern. Together, these innovations can enable manufacturers to increase the light output, expected lifetime and omni-directionality of their designs.

“The high reliability of the ceramic based XQ-B LED allows us to offer a high quality solution that does not compromise on lifetime," says Martin Hockemeyer, Vice Chairman of the Board of TELEFUNKEN Licht AG. “The unique optical advantage of the XQ-B gives us the opportunity to create the brilliant look that our customers are looking for."

“Once again, Cree is creating innovative solutions to allow our customers to differentiate their products," says Paul Thieken, Cree director of marketing, LED components. “Unlike other mid-power packages, the XQ LEDs allow lighting manufacturers to meet their light distribution requirements using fewer LEDs without giving up the performance or reliability that they expect from Cree’s lighting-class LEDs."

The XQ family includes two new LEDs, the XQ-B and the XQ-D.

In cool white (5000K), the XQ-B LED delivers up 160 lumens-per-watt at 0.18W.

The XQ-D LED delivers up to 130 lumens-per-watt at 1W.

Both LEDs are available in 2700K to 6500K colour temperatures with a minimum 80 CRI option.

Cree XLamp XQ LED samples are available now and production quantities are available with standard lead times and can be ordered on the firm's website.



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.
