Osram LEDs approach theoretical Vf limit

According to Osram Opto, its blue die are approaching the theoretical limit for forward voltage. Having shaved 20mV off from production leds last summer “In the laboratory we have already succeeded in further reducing the forward voltage by as much as 30mV”, said Osram scientist Dr Joachim Hertkorn. “Any further…

Cree ups power in mid-power competitor

Having invented its lens-less 5x5mm MHB-A as a competitor to mid-power leds when a bit more of a beam is required, it has now extended the idea to a 7x7mm format. MHD-E and MHD-G deliver 1,800 lm at 14W and 2,500 lm at…

IR led for iris scanning in phones

Aiming at adding iris scanning to phones and tablets, Osram has introduced a low-profile 810nm infra-red led with narrow emission angle and high intensity. “A wavelength of 810 nm is particularly suitable in this regard because it provides high-contrast pictures of the irises of any colour at…
