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 ...

Osram has introduced two ranges of AEC-Q102 qualified high-CRI white leds for automotive interiors. Ostune E1608 1.6 x 0.8 x 0.6mm (real base part number KW DELSS2.CC) 1,800 – 4,500mcd (30mA 3.2Vf typ) Ostune E3030 3 x 3 x 0.65mm (real base part number KW DSLP31.CC 18 – 33 lm (60mA (2.9Vf typ) products – KW DSLP31.CC-G) 45 – 71 lm (140mA products – ...

Gaggione has introduced a 16mm diameter range of optical collimators for LED lighting, optimised not to image the die – giving a smooth beam as a consequence. Made in PMMA (acrylic) and called LLC22, they are “dedicated to single and multi-chip high power LEDs. The range is based on our patented non-chip-imaging technology. The LED chip will not be projected even with ...

If you need a seven colour (almost) zoom spotlight, Fraen and Led Engin could the companies to turn to as they make the ‘colour-mixing zoom optical system‘ and the soon-to-be-available LZ7 led respectively (link is through merintus). The ZL7 has red, green, blue, white, amber, cyan and violet die – hence almost seven colour – with die running at 850mA each (or ...

3,800 colour-tuneable lumens lm from a 12 x 12mm package, is Led Engin’s claim for its latest 80W LZP device. Light emission is from 25 die in a 6.2 x 6.2 mm square (RGB and W die), and there are lensed and lens-less version depending on your desire for lumens or beam intensity – numbered LZP-00MD00 or LZP-04MD00 respectively. For more ...

  Lumileds is emitting 40% more light from its Luxeon CoB 1216, compared with its existing CoBs in the same 28x28mm footprint. Up to 15,000 lm is available from the 23mm diameter light emitting surface (LES). Streetlights and high bay luminaires are the target, replacing 100-150W HIDs. “With the new line of arrays, customers are achieving 150 lm/W at nominal condition,” claimed ...

Osram has doubled the power handling capability of its 1x1mm die Ostar Stage LED to 30W. Each device has four die – blue, green, red and white – and each can now handle 2.5A. There is a little more information on the LE RTDUW S2WN on the Electronics Weekly news website. – Why, I ask myself, does Osram insist on having ...

Lumileds has put out a little more on Luxeon C Colors. The diagram on the right shows how it has got all the focal lengths the same for better colour mixing. It is a side view, and the small trapezoidal shapes that seem to be sitting on the die are on the front edge of the package where where the ...

Toshiba has released GaN-on-Si Leds delivering 140 lm minimum (145 lm max) at 1W and 85°C (junction) temperature, from 4A5B bins of its 3.5×3.5mm TL1L4 devices. According to the TL1L4 family short form catalogue, this efficacy stretches down to the 4,000K (CRI=70) versions. There are links to data sheets from the link. At 25°C, the figure is typically 165 lm/W. ...

Luxeon C Colors is a 2x2mm family of coloured LEDs aimed at colour mixing. To remove, or at least reduce, colour fringing and halos, primary lens focussing is matched on all products regardless of colour. In order to keep the diameter of secondary optics down for its intended narrow-beam applications, the company has chosen low-dome primary optics on the package. Initial ...
