Gaggione is highlighting adjustable beam optics for its Sirius range of LED optics. The zoom function is to allow switching between narrow and wide light distributions.   For Sirius, there are two different diameter sizes 35 and 50mm (pictured). Their efficiency is said to be up to 89%. The 35mm variant, KSIRIUS35, has a typical zoom range (FWHM – Full ...

Schott has created high-power TO-9 and SMD packages for laser diodes that have a copper slug that passes all the way through the base. The copper is brazed into position, maintaining overall hermetic sealing. From a thermal simulation that includes a laser, sub-mount and header, the company is claiming a thermal resistance around 8K/W for the TO-9 device (right). “It ...

At the Electronics Weekly Elektra Awards 2025, the entire ballroom of the Hilton Bankside rose to its feet in a standing ovation as Professor Cyril Hilsum accepted the Lifetime Achievement Award. Professor Hilsum was recognised for his lengthy career achievements and his contribution to the electronics industry over a career spanning six decades. His work at the MoD after the ...

Aiming at 800V automotive battery management, Vishay has put a 1,500V Form A solid-state relay into a 10 x 10mm 4pin SMD-8 package. Back-to-back mosfets are used at the output to switch ac or dc voltages. VORA1150 has 1,414Vpeak repetitive isolation (and 8kV transients), and a maximum leakage of 1µA. “The 4pin design allows the device to provide a 5mm ...

Powell Electronics is stocking a pair of light pipe design kits from Bivar. Each kit includes a selection of Bivar’s most popular light pipes: Panel Press-Fit kit (right) is has rigid light-pipes up to 35mm long that attach to the front panel in various ways – inlcuding nuts and press-fits – and protrude directly backwards. Some of these also protrude ...

Gaggione has created a series of 50mm acrylic optical collimators for LED lighting. Called HADAR50, they are intended to be used with white and tuneable white chip-on-board LEDs with light emitting diameters between 6mm and 16.2mm. They are mechanically compatible with various mounting bases and, for situations where beam angle has to be changed in the field, there is a ...

Toshiba has introduced four dual-channel 150Mbit/s digital isolators in 4.9  x 6 x 1.75mm surface-mount packaging. Options allow two channels in one direction, or one channel in each direction, and outputs that default high or low. They are: DCL520C00 2x forward, defaults low DCL520D00 2x forward, defaults high DCL521C00 1x forward, 1x reverse, defaults low DCL521D00 1x forward, 1x reverse, ...

Optoelectronic components play a key role in circuit isolation, control modules, and communication applications. Therefore, manufacturers like Everlight rarely limit their range to just LEDs… Below we present the offer of Everlight brand optoelectronic components. This Taiwanese manufacturer boasts over 40 years of experience in its industry. Everlight, as a highly specialized supplier, targets its offer to customers seeking universal, ...

Gaggione has introduced coloured lenses for LED streetlight to emulate older lighting styles and reduce wildlife disturbance. There are two tints: amber-yellow and amber-orange, and they are found in its Avika range. “Blue wavelengths are known to disturb the natural behaviours of nocturnal and crepuscular species. Emit wavelengths above 560nm – amber, orange and red – to limit disturbances to ...

Silanna UV has announced its SF2-3T9B5L1-TB, a Far UVC LED that succeeds its SF1 series. It can detect nitrate (NO3, NO2) in water, and carbon dioxide (CO2) and Nitric Oxide (NO) in gas. Possible applications for the LED include chemical analysis, water quality monitoring and gas sensing. SF2 The SF2-3T9B5L1-TB features UVC wavelengths down to 230nm (typical 233nm). And compared ...
