Organised by the Hong Kong Trade Development Council, the 11th HKTDC Hong Kong International Lighting Fair is open now and continues through 9th April at the Hong Kong Convention and Exhibition Centre (HKCEC). More than 1,430 exhibitors from nine countries and regions are featured, with Japan taking part for the first time.

Optical design is increasingly playing an important role in LED imaging and non-imaging applications, and Selectronic are attempting to meet these needs. Selectronic is keeping ahead of the game according to MD Kevin Dry, citing their LED integrated design for car door mirror mounted LED assemblies for indicators and integral logo lamps.

OmniVision has announced the OV2312 automotive image sensor, which enables multiple functions in one camera. This multi-functional approach reduces total system cost, space and power budget for Driver State Monitoring (DSM) and viewing applications like video conferencing.

OEM of instruments and measurement systems, HORIBA, has successfully implemented in-line, non-destructive, non-intrusive and non-contact material analysis and characterisation techniques into roll-to-roll printed electronics manufacturing to provide quality assurance and improve yield.

It has been announced that, based on user input, the latest RGB indicators from APEM are customisable and offer a vast array of colours and tones. With the mixing of primary colours (red, green and blue), additional colours are available such as cyan, magenta, yellow and white, creating the perfect custom colour option for applications.

The newly released Altos emergency luminaire from EcolightingUK is part of the company’s flagship LED high bay lighting solutions designed for use in warehouses, in manufacturing, freezers/chillers and areas with high ceilings. Manufactured by Ecolighting under strict quality conditions in the UK, Altos features top quality LEDs with a high thermal conductivity and pure light and is encased in an extruded aluminium body.

Nexperiahasextended its constant current LED driver family with eight new AEC-Q101 qualified devices to drive low- and medium-power LEDs up to 250mA. The 16V NCR32xx and 40V NCR42xx series are available in two package styles, the space-saving SOT457 (SC-74) and the SOT223 (SC-73), a slightly-larger option which delivers a higher power capability of up to 1,250mW.

Two new members of the BCR linear LED controller IC portfolio from Infineon Technologies have been introduced with the BCR601 and BCR602. The BCR601 features an innovative voltage feedback to the primary side also known as ‘active headroom control’ (AHC), enabling cost and power effective LED driver applications.

High-voltage integrated circuits supplier for energy-efficient power conversion, Power Integrations, has announced the release of the InnoMux chipset for display power supplies. The chipset’s single-stage power architecture reduces losses in display applications by increasing overall efficiency in constant-voltage and constant-current LED backlight driver stages by 50% compared to conventional solutions, achieving up to 91% efficiency.

Let's start from the begining, the earliestPCBs were very much works of art.Etched by hand, they owed more to technology from artwork reproduction than to high tech.To create these circuits copper-clad boards were used. The artwork was hand-drawn, and once the track layout was defined, it was printed onto the board as an etch-resist mask. Acid was next used to etch away the exposed copper before another chemical removed the etch resist.
