LED Lighting

Osram is showing automotive lasers amongst its offering at CES this year, including in headlights. It has a surface-mountable four-channel lidar laser with four individually controllable laser diodes and an integrated control circuit. “The new laser is a bar consisting of four laser diodes that are separated in the production process but are not individual diodes. The result is a ...

Verbatim used LuxLive in London to launch anti-glare AR111 retrofit LED bulbs and demonstrate a new range of linear LED products. Low glare is the big marketing point. “To avoid the uncomfortable glare, the lamps mimic the lighting effect of a traditional halogen lamp by emitting light indirectly via the reflector,” said the firm, which is claiming CRI >90 for the ...

Plessey has added to its Orion family of beam forming modules with +/-7.5° and +/-25° (15° and 50° FWHM) options.

OMC says it can now produce a rainbow of LED backlight colours, including magentas and blue-greens. Previously the only way to achieve non-standard LED colours was to use RGB colour mixing, which involves three times as many chips, complex wiring and requires drive circuitry to control the relative channel levels. OMC’s  Active Reflector Technology uses photon wavelength up-conversion to produce ...

Thermal interface firm Cambridge Nanotherm has expanded manufacturing to meet demand for LED thermal substrates. Its technology is a thin electrically insulating coating with high thermal conductivity for metal cored PCBs (MCPCBs). “Our MCPCBs offer designers a distinct thermal advantage. Demand for our solutions has therefore been strong, and we’re currently engaged with most of the top ten LED manufacturers,” ...

A German research alliance has taken the next step in car front lighting with a 1,024 pixel LED for matrix headlights. Matrix headlights are effectively projectors, capable of sending individual beams of light in front of the vehicle an, in conjunction with cameras and algorithms, allowing the parts of the beam that would dazzle on-coming drivers to be turned off ...

UK lighting LED maker Plessey introduces its first lighting module, which includes 'Stellar' beam-forming technology to reduce height, to 5.6mm.

Rohm will show matrix-style LED headlamp controllers at Electronica in Munich in November. Matrix headlamps use an array of LEDs to allow arbitrary beam shapes to be produced – dip, main, anything in between, and anti-dazzle dark spots withing beams. “Matrix/Pixel LED dynamic front lights and dynamic sequential turn indicators mark the latest developments in exterior lighting,” said the firm. ...

Cree’s lighting division has created a range of high-end high-efficiency LED replacements for incandescent light bulbs. The 100W replacement, for example, achieves a highly creditable 100 lm/W – delivering 1,650 lm from 16.5W. What makes this remarkable this is the 2,700K (warm) white version, with a CRI of 85, and the bulb is dimmable – dimmability can cost up to ...

For automotive leds arrays, Allegro MicroSystems Europe has announced two adjustable linear current regulators.
