The latest Electronics Weekly product news on LED lighting (light-emitting diodes – a semiconductor light source).
TT Electronics of Woking has introduced a compact, infrared LED emitter with a spot diameter of 7mm for super-reliable optical sensing and position encoder applications. With up to 10mW total radiated power at the maximum drive current of 100mA, and 2.25° angle of half intensity, the OP207CL couples optical flux extremely efficiently onto the receiving photo-sensor to ensure clearly detectable ...
Diodes has released simple LED driving chips for regulating current in strings of LEDs, particularly in cars and other road vehicles – some of which match parts from Infineon and Nexperia (see table below). Called the the BCR4xxUW6Q series, they come in SOT26 (SC70) packages and are expected to find use with LEDs displacing conventional bulbs throughout the car: from external ...
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 ...
