Lights are the most prevalent electrical components in any commercial building, and that makes them the most logical devices for smart building sensors, according to Russ Sharer, vice president of global marketing and business development at Fulham. “In new construction you can plan to use standalone smart building control sensors, but only 8% of commercial space is new construction. However, ...
Devon-based Plessey has launched another Hyperion-branded horticultural product line – this time a luminaire to spread light at leaf level – to complement its horticultural down-lighter. “Placing lighting within the canopy of high wire plants is an energy efficient way to increase light levels and yields in greenhouses that already have supplementary top lighting,” said the firm’s director of grow ...
For pendant or wall use, Hong Kong-based Candelec has announced Ring300 and Ring400 – 300 and 400mm in diameter respectively. Both have 100-240Vac inputs, consuming 25 or 35W respectively and emitting 1,750 and 2,835 lm in warm white form. They also come in cool white, with an increase in lumens. Colour rendering index is >80, and they are rated across ...
Over Bluetooth, this luminair’s beam can be adjusted from <10° to 50°, flowing fluidly through all the all points in between, according to manufacturer Formalighting. Development was with beam shaping specialist LensVector and wireless firm Casambi. Direction (pan and tilt), intensity and colour temperature are also adjustable, in what is to be called Moto-Ola Track. LensVector’s ‘dynamic beam shaping’ technology ...
Lumileds has introduced a line of leds for plant growth rate and crop yield for plants and vegetable. Called Luxeon SunPlus 2835, “growers can choose a specific colour point using Purple or Horticulture White leds, or design a spectrum using the Deep Red, Far Red, Lime and Royal Blue emitters”, according to the firm, which claims: Horticulture White provides a ...
Osram leds are to provide light throughout Saint Peter’s basilica in Rome, aiming to save 85% of power consumption. Said to be the largest church in the world, it is enormous – holding a congregation of 20,000, it is around 190m long, the three naves each 58m wide, the central nave 45.5m at its highest point, and the cupola about ...
Luxeon 2835 HE is a 200 lm/W led from Lumileds, which is it is aiming at luminair manufacturers wishing to reduce LED count such as troffers, high bay and low bay fixtures. It is available in 2-step MacAdam ellipse colour consistency versions “The LED’s tight colour point distinguishes it from other mid power devices in its class,” said Lumileds product ...
Aiming at projection headlamps, Osram Opto has built an led that can handle 3A/mm2 through its 2mm2 chip, emitting at least 1,400 lm at 6A. All this is to get high luminance – light output per area – which is the key to compact projection systems, and the reason we are hearing about laser headlights. The firm is claiming >200cd/mm2 for this ...
Osram has introduced SFH 4776, a boadband infra-red in the firm’s 2.75 x 2.0 x 0.6mm high Synios package. The technology inside is a blue-emitting GaN die and phosphor converter, specially developed for spectroscopy, that converts the blue light into radiation across 650 to 1,050nm. “By making improvements to the phosphor material, developers at Osram Opto Semiconductors have succeeded in increasing the intensity ...
Ledil’s Daisy is a lens/shroud combination intended to cut glare “Tin offices. Beam angle is ±40°, with pretty even illumination across ±30°, and it comes in x4 and x28 versions – the latter 1.140m long. Optimised for 2835 leds, it is compatible with packages up to 5630, said the firm. With Samsung LM28xB leds, the figures are: ±39°, 84% efficiency (“High efficiency, despite ...
