Advanced Energy of Colorado has introduced single-phase hot-swappable PSUs up to 4kW for horticultural and commercial LED lighting. “Indoor growers are turning to centralised power systems that distribute dc rather than ac power directly to individual LED lamps”, said company v-p of industrial power Joe Voyles. The supplies, called the LCM4000HV series, are compliant with DesignLights Consortium (DLC) technical requirements ...

A new partnership between Anglia Components and Cumbria-based LED manufacturer, Marl International, cements the distributor’s status as Master Distributor for the UK and Ireland, covering the full range of panel lamps, PCB mounting indicators and other standard LED components. As Master Distributor, Anglia will carry “an extensive” stock of standard devices for customers and for other resellers, but will also offer support ...

Toshiba has introduced a photo-relay capable of operating with 1.5kV across its output switch – the company’s first with such an output withstand voltage – “ensuring that it is compatible with the vast majority of traction batteries”, it said. AEC-Q101 qualified and aimed at battery management systems, TLX9160T consists of an infra-red emitting diode optically coupled to back-to-back photo-mosfets. Although intended ...

Osram has revealed a prototype laser emitter module for projection within augmented reality glasses. The lasers are 640nm red, 520nm green and 450nm blue, in a 7 x 4.6 x 1.2mm (39mm3) surface-mount package. Branded Vegalas, the “prototype design for the module demonstrates that a light engine for smart glasses can be compact enough to fit in standard consumer fashion frames”, ...

Anglia Components has signed a UK and Ireland distribution  agreement with Chinese LED maker Ekinglux. “We are always seeking to strategically expand our supplier base to stabilise our supply chain.,” said Anglia technical director David Pearson, “The addition of Ekinglux, one of China’s top ten LED manufacturers, widens the range of optoelectronics devices we offer. Ekinglux has an excellent reputation for quality and ...

Toshiba has launched three quad Form-A voltage driven photorelays, claiming one of them with one of the smallest mounting areas in the industry. They are Toshiba’s first four-circuit, 4-Form-A, relays, in a 12.5mm2 (2 x 6.25 x 1.3mm) package dubbed S-VSON16T. “The area is approximately 14% less compared with the mounting area of four one-channel relays,” according to the company. ...

Osram has introduced a laser diode for industrial lidar. SPL TL90AT03 emits 905nm infra-red and has been developed for short laser pulses – between 5 and 100ns – maximum duty cycle is 0.1%. Optical output is 65W from a 110µm aperture (20A 100μs 1kHz) – said to be an efficiency of 34%. There are three emitters inside the package – forward ...

Allegro MicroSystems has added two LED drivers to its automotive portfolio. A80803 is a boost and buck-boost dc-dc converter for headlights, that includes switching for high-beam and dip-beam strings. It works with inputs over 5 to 37 V (40V abs max for load dump, 4.5V under-voltage lock-out). Output can be up to 70V Drivers are included for external high and low-side dc-dc mosfets ...

The Thomas Pocklington Trust has once again updated it guide for lighting spaces in which partially-sighted people live, and has broadened its appeal to beyond its original intended audience. “Lighting makes such a difference for partially sighted people, often enabling them to maintain their independence,” the Trust told Electronics Weekly. Now at issue 3, ‘Lighting in and around the home: A ...

Osram has introduced horticultural lighting leds with a ‘batwing’ output distribution. Implemented in Oslon Square Batwing, the distribution comes purely from a primary lens built into the pacakge. “Current LED fixtures often have a lambertian primary lens and no secondary optic, or a simple glass cover, which lead to hotspots with high concentration of light directly under the luminaire,” according ...
