LED Lighting | Electronics Weekly

Vishay has announced an AlGaN mid-power ultra-violet LED for water purification, air purification, surface sterilisation, medical disinfection, and portable sanitisers. Called VLMU35CM00-280-120, it comes in a 3.5 x 3.5 x 1.2mm surface-ceramic mount package with a quartz window. Because of this construction, the firm is claiming “extremely long lifetime” – however, nowhere in the data sheet nor the product page can I find any ...

Green laser for smartphone RGB projectors

31st January 2019 LED Lighting

LED Lighting | Electronics Weekly

Osram has released a green laser for phone-based projectors, capable of delivering 140mW pulses. Although a projector also needs red and blue lasers, green is the colour that poses the greatest challenges in semiconductor laser and LED production. “Up to now, RGB laser projections for smartphones, based on a red, green and blue laser, often had brightness problems,” according to ...

Osram’s second-generation headlight lasers

29th January 2019 Automotive Electronics, LED Lighting

LED Lighting | Electronics Weekly

Osram has released the second generation of blue multi-mode laser diodes for car headlights, doubling range in auxiliary high beams compared to with its previous lasers, to 600m, it claims. What lasers offer over LEDs as a light source is higher light output per unit area (luminance) – which then allows a slimmer smaller optical chain for a given final ...
