No-solder package will approach 150 lm/W

It is not often you hear of a new packaging concept for LEDs. Three days ago Litecool of Sheffield got patents for an adhesive-backed one – that can be pick-and-placed straight onto a heatsink. Carclo 10mm lenses can be places straight on top. Not only that, but it…

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…
