Cree's New XLamp LED Arrays Double Lumen Density

The CXA high-density III-nitride based arrays enable the next generation of LED spot lights


Cree has announced what it says is the industry’s first High-Density (HD) LED Arrays - a breakthrough technology that doubles the system intensity of spot lights compared to previous arrays.

The new HD class of CXA Arrays provide unrivalled lumen density, enabling major reduction in system cost and power consumption.

The first HD Array, the CXA1520 LED, enables lighting manufacturers to create a new generation of products that delivers the same intensity and light quality as 39-W ceramic metal halide (CMH) at up to 50 percent lower power.

“The new CXA1520 LED Array delivers an impressive amount of light from a very small source. I have not seen another integrated array that can match this level of lumen density," says Mark Groenke, VP of engineering at ConTech Lighting. “The CXA1520 LED Array enables ConTech Lighting’s newest LED fixtures to exceed the efficiency and life of our ceramic metal halide fixture offerings while maintaining intensity and colour quality."

The High-Density Cree XLamp Array extends Cree’s robust CXA family to give lighting manufacturers a single integrated array family to address lighting applications from general-purpose floods to specialty retail spot lights.

Cree XLamp CXA1520 LED Arrays deliver up to 3478 lumens at 33 watts, 85°C. Available in ANSI White and four-step EasyWhite binning, the new arrays feature 2700 K through 5000 K CCTs, with 70, 80 and 95-CRI options.

“We have several CXA1507 and CXA1512 LED array designs, and we’re excited that the new CXA1520 LED Array shares the same light-emitting size as the CXA1507 and CXA1512 LED Arrays," says Tom Tang, chairman and CEO, Tons Lightology, Inc. “This allows us to address very-high output applications without changing the optics."

XLamp CXA1520 LED Array samples are available now, and production quantities are available with standard lead times.



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.
