Led Luminaries

Gaggione and LensVector have teamed up to create an electronically-shaped narrow beam light engine. It combines Gaggione’s LLC66N7 67mm narrow beam collimating optic with LensVector’s 65mm M2M liquid crystal lens (black-edged front optic in image right) – to the collimator has to be added a lens holder (far below) making ‘LLS66NCLV assembled set’. “This complete, modular drop-in optical system solution enables digital control from ...

Nichia is claiming better colour rendering without loosing efficacy with technology it has banded ‘H6’. “Indeed, the H6 series delivers a colour rendering index of 90 while maintaining a level of efficacy seen in standard CRI 80 leds,” it claimed. It takes advantage of a red narrow band phosphor, as well as semiconductor and package changes, to “achieve a colour quality better ...

Gaggion has removed the moulding sprue from the alignment edge of its LLC25x colour-mixing collimator range, so they will now sit flush on a flat mounting annulus, with no need for a notch. These are 32mm optics, with non-chip-imaging characteristics to create even beams from single or multi-chips RGBW, tunable white or standard white leds. See the link above for characteristics. ...

Nichia is claiming two functions for its latest LED – illumination and bacterial ‘deactivation’ in its words. “It has been well-known for years that UV-C and UV-B wavelengths, ranging from ~200-380nm, has been used for disinfection,” said the company. “However, it has recently been proven that visible light, ranging from ~380-420nm, also has a bacteria disinfection effect.” So it has ...

Osram has put a 2.1 x 2.1mm die into a 2.4 x 2.4 x 0.6mm package to create an LED for outdoor lighting. Called Osconiq C 2424, “because the package and chip have approximately the same dimensions, it is considered a chip-scale package. This allows the individual LEDs in the luminaire to be placed close together, ensuring particularly homogeneous illumination”, ...

Oak Island Lighthouse in North Carolina is the first in the US to get a rotating led beacon – a few others have been retrofitted with static led lamps. UPDATE: The Friends of Oak Island Lighthouse have sent a spec for the light (see below) “This upgrade is the Coast Guard’s first led-based rotating beacon for an active aid to ...

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 – ...

Zhaga will allow an ANSI C136.41 dimming receptacle to be combined with a Zhaga receptacle in the planned 3rd edition of its Book 18 specification for outdoor luminaires. Book 18 3.0 will enable Zhaga-D4i certification of hybrid luminaires as well as control devices with an ANSI interface in addition to the certifications already offered by Book 18 Ed. 2.0. While ...

In tests conducted with Yamaguchi-University, Stanley Electric has achieved 99.9% ‘inactivation’ of Covid-19 virus SARS-CoV-2 using its aluminium nitride-based 265 nm UV-C leds. Inactivation here, said the company, is defined as the inability to multiply after exposure through damage to DNA and RNA. “10ml of virus solutions [5 x 105 PFU/ml] in dishes were irradiated with 265nm UVC LED at ...

Osram has increased the efficiency of its broadband near-infra-red emitting diodes (NIREDs), producing the Oslon P1616 SFH 4737 which it claims is world’s smallest NIRED aimed at spectroscopy in phones, at 1.6 x 1.6 x 0.9mm. “This product will soon make mobile spectroscopy solutions a reality,” according to the company. “It is not only its compact design that makes this NIRED ...
