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”, ...

Mallory Sonalert has a series of 31mm diameter indicator lights in one, two or three colours selected from red, yellow and green. Called Stacklights, they mount with an M22 thread through a 22.5mm hole. Some versions have the lights just above the mounting surface and some are extended 100mm above the mounting surface (see photo, tall lights are further away). ...

Cree has agreed to sell its LED business (‘Cree LED’) to memory maker Smart Global Holdings. “We are pleased to announce the sale of our LED products business to Smart, which represents another milestone in our journey to create a pure-play global semiconductor powerhouse,” said Cree CEO Gregg Lowe. “This transaction positions us with a strategic focus to lead the ...

ON Semiconductor has introduced a 2.3Mpixel 120frame/s global shutter image sensor for machine vision and mixed-reality displays. Called AR0234CS, te CMOS sensor captures 1080p video and single frames, and “produces crisp and clear images by minimising frame-to-frame distortion in high-speed scenes and reducing the motion artifacts”, according to the company, which also sees the device being used in AR headsets, VR headsets, autonomous mobile ...

Vishay has introduced a pair of surface-mount PIN photodiodes in black packages whose opaque side walls eliminate unwanted illumination to increase their signal to noise ratio. AEC-Q101 qualified for automotive use, VEMD4010X01 and VEMD4110X01 come in a 0805 case size with an 0.7mm profile – 0.15mm lower than previous-generation devices. Sensitive area is 0.42mm2. VEMD4010X01 is sensitive across 550nm to 1,040nm VEMD4110X01 is ...

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 ...

Melexis, the Belgian automotive IC specialist, Has introduced a multichannel RGB-LED driver. The MLX81116 supports the MeLiBu high speed communication IP to enable intelligent animated automotive lighting concepts. An increasing number of car manufacturers are looking to introduce animated lighting into the cabin, as a way of conveying important driver-assistance prompts and vehicle-status information. Current design thinking envisions using an RGB-LED ...

Toshiba has introduced a pair of linear CCD image sensors for automated optical inspection and  barcode scanning. Both are monochrome and have a 5.25μm (pitch) x 50μm pixels stacked edge-on to form an array ~7.9mm long. TCD1105GFG has 125V/lux-s sensitivity and 90 dynamic range, plus built-in electronic shutter. TCD1106GFG has 600V/lux-s sensitivity and 400 dynamic range. Dynamic ranges are defined as (saturation output ...

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 ...

A German project has revealed 400W infra-red laser diode bars for welding metals. “About 10 years ago, the best laser bars achieved a power of 200W with an efficiency of about 63%,” according to Osram. “Five years later, an output of 250W at an efficiency of no less than 60% was expected to be the limit of what could be ...
