Cree has released preliminary data on the lens-less ‘high intensity’ (HI) variant of its recently introduced XPG-4 leds (3A 10W 3.3 x 3.3mm). “A first in the XPG series, this version promises unparalleled candela and throw for the most demanding lighting needs,” according to component distributor Cutter Electronics, which will be stocking the parts – and pointed out that the ...

Cree LED has added higher efficiency high colour rendering index versions to its XHP35.2 leds, and introduced leds optimised to dim evenly when used in parallel The company has used its latest phosphor fill technology between the led die for improved optical performance. Optimised for indoor directional lighting, “Pro9 versions of the XHP35.2 HD and HI leds have up to ...

Cree is aiming at directional lighting applications such as spotlights, premium torches and sports lighting with the XP-G4 re-work of its XP-G series of leds, increasing energy in the beam while reducing side-spill, increasing maximum drive current, and reducing thermal resistance. Update: Lens-less ‘high-intensity’ variants were announced in January 2024 It is also harking back to now-unobtainable ‘pre-PCN’ XP-G2 leds ...

Cree LED has introduced 5 x 5.2mm 6V LEDs (o.75mm thick) that can deliver up to 480 lm at 400mA (5,000 or 5,700K, 70CRI, 25°C). Called ‘J Series 5050C E Class’, they can be identified by part numbers of the form: JR5050Cxx-E-….. Maximum current is 1A, and light output increases almost linearly with current, but drops with temperature – 480 ...

Cree is aiming at premium indoor and outdoor lighting with a family of metal-substrate CoBs called CMB, tuned as performance upgrades from its CXA, CXB and CMA families, while retaining mechanical and optical compatibility. “Up to 8% improvement in lumens/W vs previous generations by leveraging the latest technology platform,” is the company’s claim. They are “drop-in upgrades for Cree LED ...

Cree has shaken up its website, adding parametric search amongst other changes. “On-line interactive product search tools enable customers and users to perform a parametric search across all Cree led products,” according to the company. “This search capability is accessible on the ‘Products’ and ‘Applications’ pages, and offers filters for sorting by product type, voltage, colour and optical characteristics like ...

XLamp XHP70.3 leds are the third generation of Cree’s ‘extreme high power led series’, with improved optical performance versus the previous generations, with higher intensity through optics than the second generation and with the XHP family’s highest on-axis intensity. They are optimised for outdoor and lighting applications that require large amounts of light output from small luminaires, such as in ...

This is accidentally becoming an epic – exploring the combination of Cree’s high intensity XP-P led and Gaggione’s rectangular beam LLC15E optic. One of the problems of using a new led-optic combination where no specific data is available, is working out the correct distance between the led mounting face and the lens mounting face. Having printed a quick fixed lens ...

Got a chance to design and print a quick lens holder to try the 16mm separation which I calculate should be the correct spacing for the mounted Cree XP-P led and Gaggione LLC15E that have arrived. DesignSpark Mechanical used (still too far down the learning curve to risk FreeCAD), and I knocked some holes in the side of the model ...

Thanks to Cree, there are now some XP-P led samples at (virtual) Electronics Weekly Tower. I was dying to experiment on some, and they were proving difficult to buy. They arrived beautifully packaged and even vacuum-wrapped. XP-P is Cree’s high-intensity led for long narrow beams – it has a 9Wmax 1 x 1mm die with no primary lens. My aim ...
