Osram adds to its Oslon Black portfolio for infra-red illumination with a ±25° narrow beam version

LTM8005 from ADI operates from a 5V to 38V input voltage range and can deliver up to 1.6A of regulated output at up to 38V – provided the necessary external capacitors and inductor are added, and the maximum 10A switch current is observed. Buck-boost, buck and SEPIC topologies are also available from the same module, which comes in a high ...

Toshiba is targeting automotive applications with a high-speed analogue-output optocoupler. Comms in electric and hybrid-electric vehicles is the main target. TLX9309 is AEC-Q101 qualified and consists of a GaAlAs LED optically-coupled to a photo-diode backed by an amplifying transistor. By separating the photo-diode and amplification transistor, said the firm, collector capacitance is reduced, cutting  propagation delay – times are guaranteed ...

Russ Sharer, of Fulham, spells out four reasons for using LED lighting as the hardware foundation for smart city IoT connectivity.

The ADPD188BI is an integrated optical module featuring two LEDs, photodiode, and analog front-end (AFE) integrated together in a single package. The AFE offers high ambient light rejection and reduces power consumption to support longer battery life. The two LEDs help reduce false alarms often caused by steam and dust. False alarms are a leading factor in detectors being removed ...

Rich Miron, of Digi-Key, recommends some products that can help to deliver the extra features that LED lighting systems promise Solid-state lighting and high brightness LEDs are changing the way we see the world, quite literally. The environmental benefits of LED lighting are two-fold. First, the technology itself is a highly energy efficient way of generating photons, which makes it attractive ...

Plessey ties up with Vuzix to develop augmented reality glasses

Diodes Inc has created a family of two-pin constant current chips that can work at up to 400V. Intended to control strings of LEDs running direct from rectifier mains, and called AL5890, it is available 10mA, 15mA, 20mA, 30mA, and 40mA variants “Its simple two-pin design means it can be inserted directly in the LED string in low-side ac or ...

An LED street light wireless luminaire controller compliant with the LoRaWAN standard.

Toshiba has started to ship five new high-current photorelays in DIP4 and DIP6 packages. These additions to its portfolio of photorelays incorporate MOSFETs fabricated with the latest U-MOS VIII process. There are a total of five new photorelays (TLP3543A, TLP3545A, TLP3546A, TLP3556A and TLP3558A). Together they offer multiple options, with an off-state output terminal voltage (VOFF) ranging from 30V to ...
