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 ...
Gaggione simplifies fitting of LLC25x collimators
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 LED disinfects as it illuminates
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 aims at outdoor lighting with 2424 chip-scale LED
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”, ...
Updated: First rotating led lamp in a US lighthouse
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 ...
High CRI white leds for automotive internal lighting
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 adds ANSI C136.41 dimming to outdoor luminaires in Book 18 v3
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 ...
Stanley Electric tests UV-C leds against Covid-19
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 ...
74mW broadband IR LED for phone-based spectroscopy
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 ...
Surface mount clip makes Ledil lenses a snap fit on pcbs
Ledil has come up with a surface-mount soldered metal clip that allows led lenses to be mounted on a pcb without adhesive. Said to be vibration resistant, the clips, called ‘Solder-Clip’, are used in pairs with special holders for the company’s 22mm Leila lenses and 16mm Tina lenses – Leila-SC and Tina-SC variants to be precise. The clips have a ...
