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 ...
Update: Thanks to Ledil technical marketing manager Samuli Saransalmi for getting in touch to fill in some details (integrated below) on this interesting optic. Ledil is aiming at architecture narrow-beam wall-washing with a sharp cut-off lens called Leia – achieving beams around ±1.5° (3° FWHM) with single chip 3535 high-power LEDs, with a “very strong cut off,” said Saransalmi. “There is very little ...
I took my eye of the ball and missed Gaggione’s LLC25N collimator, which was released at the end of last year. See also this update It brings the firm’s colour mixing technology to its 32mm diameter form-factor, providing “state-of-the-art colour mixing for RGBW or tunable white applications”, claimed Gaggione at the time. “It is also capable of great beam results ...
Cree has introduced an ‘S Line’ version of its XP-G3 led line – the remainder is now called ‘Standard’. “Through innovations in component architecture, the new XLamp XP-G3 S Line LED can withstand double the number of switching cycles when compared to competing leds in its class,” said Cree in the launch paperwork – leaving me to wonder if the ...
