Gaggione is focussing on narrower beams with two acrylic collimators and a set of radial beam masks. LLC22R (pictured) is a 16mm collimator claimed to achieve ±4.45° (8.9° FWHM) and 34.2cd/lm with Cree XP-P leds. Emitters up to 5 x 5mm can be accommodated. LLC25R is a 32mm collimator claimed to achieve ±2.15 (4.3° FWHM) and 149.9cd/lm with Cree XP-P ...

Circular emitter LEDs for beam-forming
Cree has introduced a pair of circular emitter LEDs with no over-die lens for beam-forming applications. Colour temperature options are 5,000, 5,700 or 6,000K. “These LEDs deliver smoother, more focused light output through optics compared to traditional square LES designs – perfect for premium flashlights, torches, bike lights and headlamps,” according to the company. Using the same 3.45 x 3.45mm ...
How not to attract birds to off-shore platforms
How do you stop migrating birds from being attracted to oil rigs at night? The reasons that they should not land are two-fold: the mess that they make adds to maintenance costs, and birds that land are more likely to die before competing their journey. “Offshore platforms, such as oil and gas rigs, wind turbines, and their substations, offer a ...
Cree boosts horticultural red led efficiency
Cree is aiming at horticulture lighting with a 660nm red led that is 6% more efficient than its XP-G3 Photo Red S Line devices. Called the XP-L Photo Red S Line, “this extra performance can be used to lower Photo Red LED count in luminaires by 35% while still maintaining the same total system efficiency”, according to the company. A typical ...
LED streetlight lenses from recycled plastic
Gaggione is offering versions of its Avika range of LED streetlight lenses made using recycled plastic. We are “incorporating recycled PMMA into our range, derived from recycled industrial scraps”, according to the company. “Our team selected one of the most transparent recycled materials on the market: recycled Plexiglas 8N. This material, both lightweight and durable, guarantees high performance in ...
Zhaga standard for linear socketable LED modules
LED lighting body Zhaga has released a standard for ‘linear socketable LED modules for non-SELV applications’ – Zhaga Book 26 – intended luminairs with LED modules that can be replaced without tools and that simply plug into internal wiring. Earlier Book 21 covers ‘linear socketable LED modules for SELV applications’ – SELV is an acronym for separated (or safety, depending ...
Cree boost output of XE-G colour led range
Cree LED has up-graded its 1.6 x 2.05mm lens-less XE-G led family, claiming a 20% increase in efficiency for RGBW systems, and a 10% or higher efficiency gain for 13 of the 18 available colors. These devices are intended to be packed closely under colour-mixing optical systems. As such, the gap between emissive surface and package edge is kept small ...
16,500 lumen LED for flashlights is not an exaggeration for once
Cree LED is aiming at portable lighting with a 16,500 lumen multi-die LED in a 10 x 10mm package with a 9mm primary lens (right). Called XFL10K, it has two cousins: the 14,247 lm XFL08K which comes in the same package, but with an 8.5mm lens, and the 7 x 7mm 8,335 lm XFL05K with a 6mm lens. These are ...
Luceco re-lights Bolton Arena Sports Village tennis halls
Contractors picked Luceco luminaires on behalf of Bolton Arena Sports Village to upgrade the 15-year-old lighting in its giant Tennis Halls. “This presented us with a great opportunity to both look for an energy-saving solution as well as an upgrade to the quality of the lighting,” said Bolton Arena operations manager Simon Sharrock. Out went fluorescent lighting and in came ...
Cree talks about tuneable white errors
Cree has been experimenting with tuneable white luminaires, and has published its findings in a couple of useful application notes. XLamp XD16 premium white color-tunable LED arrays reference design 3-channel white tunable 1000 lm 4” downlight reference design One conclusion in both cases is that three-channel colour mixing achieves a wider colour temperature range for any given maximum deviation below ...
