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 ...

New Yorker Electronics acquires Omni Pro Electronics
Pursuing a growth by acquisition strategy, New Yorker Electronics, has announced the acquisition of Texas-based electronic component distributor, Omni Pro Electronics. “The purchase of Omni Pro is an integral component of our aggressive acquisition plan,” said Barry Slivka, president of New Yorker Electronics. The company is actively identifying companies that fit its acquisition model, he added. New Yorker was founded in ...
‘Zero temp-co’ current limiting diodes up to 575mA
Central Semiconductor has created a line novel of zero temperature coefficient current limiting diodes, packaged in DPAK and rated at between 27 and 575mA. Minimum voltages range across 1.5 to 2V – see table. Manufactured in the industry standard DPAK surface mount package, these Industry First devices are “This technology is a distinct innovation in current limiting device technology,” said ...
75W laser for vehicle lidar, with a 120W version in the pipeline
Rohm has developed a 75W laser diode for lidar in automated guided vehicles, service robots and robot vacuum cleaners. “In recent years, lidar is being increasingly adopted to precisely measure distance and for spatial recognition. For such markets, there is a need to improve the performance of laser diodes to increase detection distance and accuracy,” according to the company. The ...
100V mosfet relay leaks only 1pA at 80V
Omron has released 100V and 800mA versions of its low-leakage ‘T-configuration’ mosfet relay modules. “T-modules offer the reliability and durability of solid state relays combined with an exceptionally low leakage current of just 1pA or less, allowing their use in measurement and other applications where mechanical relays have previously been preferred,” according to the company. G3VM-101MT handles 100V and 550mA, and G3VM-61MT ...
UK made: Glass chip couples to optical fibres to silicon photonics
Optoscribe is sampling optical fibre to silicon photonics couplers. Branded OptoCplrLT, the devices are monolithic curved glass mirrors which turn light to direct it to or from silicon-photonic grating couplers (see diagrams). “This prevents the need for bend-tolerant fibre solutions which have some significant limitations in size and profile,” according to the company. Made using a proprietary laser writing technique, ...
Disinfection LEDs from Anglia
Anglia Components has begun stocking UV-C ultra-violet LEDs from Bolb. “UV-C LEDs are gaining attention because they provide robust, toxic-free disinfection,” said Anglia marketing director John Bowman. “The addition of Bolb’s products to Anglia’s line up is an important step as we look to offer customers solutions for sterilisation that will play an important role in the post-Covid world.” Some ...
Osram turns to quantum dots for 90CRI lighting LEDs
Osram has developed its own emissive quantum dot technology, and is using it in a range of 90CRI lighting LEDs. “‘Osconiq E 2835 CRI90 (QD)’ pushes efficiency values to new heights, even at high colour rendering indices and warm light colours,” according to the company. “The LED meets the requirements of the Single Lighting Regulation [mandatory in Europe in September ...
Ad-dc chip drives LED lighting at 125W
Infineon is aiming at LED lighting with a family of single-stage fly-back off-line controller chips for constant voltage outputs. Called ICL88xx, up to 125W can be delivered in primary-side-regulated (right) and opto-coupler secondary-side-regulated configurations. They are optimised as secondary-side regulated constant-voltage output controllers. ICL8800 is the basic variant ICL8810 has added burst-mode operation for <100mW stand-by consumption “and flicker-free deep dimming ...
Tiny dot projector lets cameras get to grips with a 3D world
Osram has announced a tiny projector that sprays 4,700 random dots into space to allow stereoscopic cameras to measure a 3D environment. Called Belago 1.1, it combines a 940nm VCSEL infra-red laser with a micro lens array, all in a 4.2 x 3.6 x 3.3mm package. The dots cover an angular field of 61° horizontally (FWHM) and 78° vertically . Non-periodic dot projectors ...
