Led Luminaries

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 ...

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 ...

Delta has introduced a 1.5kW version of its Euco Arena Sport led drivers for industrial and commercial lighting applications, such as high mast, recreational sports, harbours, airports, and parking areas. There are three 500W outputs, dimmable across 0.1% to 100% under DALI-2 digital control. Inputs are accepted between 198 and 440Vac (47-63Hz), and output is 250V~500Vdc programmable across 500mA – ...

Gaggione has introduced a 16mm diameter range of optical collimators for LED lighting, optimised not to image the die – giving a smooth beam as a consequence. Made in PMMA (acrylic) and called LLC22, they are “dedicated to single and multi-chip high power LEDs. The range is based on our patented non-chip-imaging technology. The LED chip will not be projected even with ...

Osram with LK Technology lit the top of Southeast Asia’s tallest building: 461.5m Landmark 81 in Ho Chi Minh City Vietnam. More than 12,500 luminaires are apparently involved, with control though Butler S2 DMX engines and a Lighting Control Engine2. “The facade lighting of Landmark 81 is an example of how dynamic illumination can be used to re-define city nightscape,” ...
