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 ...

Signify has retrofitted the twin 4.5km bores of Dublin Port Tunnel with led lighting. “The upgraded lighting has achieved up to 60% reduction in electricity use, based on 2022 rates,” it said. “The project is expected to save upwards of €4m in electricity costs including VAT over the coming five years.” The existing fittings were re-used “saving an estimated €3m ...

After three years of development, the Nichia – Infineon micro-led-based light engine for matrix-style vehicle headlamps will be seen “in a German premium vehicle” this year, according to Infineon. Matrix headlights use projection optics to project an image of a rectangular array of light sources (in this case ‘micro-leds’) ahead of the vehicle, allowing any shape of headlight beam to ...

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 ...

Tridonic is aiming at high-ceiling industrial led lighting with a 220W harsh environment constant-current driver. ‘LCI 220/500-1400/300 pD NF h28 PRE4’ (trips off the tongue… Ed) works across -40 to +75°C and is intended to work for 100,000 hours at an ambient temperature of 65°C. It is dimmable and has an integrated DALI bus power supply for D4i luminaires. Configuration ...

Gaggione has produced a family of 45mm collimators for cob (chip-on-board) leds. VEGA45V produces a 50° beam Called Vega, they follow on from its 45mm LLC59 colimators. Like LLC59, Vega collimators will be available in PMMA plastic, but also in polycarbonate. There are eight beam options, some of them compatible with colour mixing or tunable white use. Compatibility is said to ...

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 ...

Led lighting certification body Zhaga has announced the first products that have met its ‘Book 24’ definition of luminaires that can be programmed over NFC (near-field communications). “Tridonic is the first company that has earned Zhaga-NFC certification for a number of their LED drivers [right],” according to Zhaga, and they can now carry the Zhaga-NFC certification logo. Book 24 application ...

GlacialPower of Taiwan has announced a 300W constant voltage led driver series that supports triac dimming. Called GP-CVM300P-xxVH , they come in 12, 24, 36 and 48V models. “At full load these new drivers provide active power factor correction of more than 0.94 at 230Vac,” according to the company. They deliver “power efficiency up to 92% and no-load power consumption ...
