UV LEDs, capable of producing UVA, UVB and UVC radiation, are quickly overtaking incumbent lamp technologies such as mercury. The market is expanding rapidly, Yole Développement expect the UV LED market to grow to $270M by 2017, and as much as $300M if new applications come online. Yole point out that the compactness, low cost of ownership and environmentally friendly composition of UV LEDs are driving both the replacement market and opening up completely new markets to UV lighting. From printing to adhesives, through tooth whitening to water purification, UV LEDs are transforming the industry.
Whilst the benefits are clear there is a downside: the sheer amount of heat generated by the LEDs. More than 90% of the energy used by UV-C LEDs is wasted as heat. Compare this to around 60% for standard LEDs and you get an idea of the scale of the challenge.
Nanotherm can help UV LED manufacturers manage the big thermal challenges they face. Nanotherm LC is a revolutionary nanoceramic Metal Clad PCB (MCPCB) substrate that combines the best of both aluminium and ceramic. Nanotherm LC is considerably more thermally effective than any alternative MCPCB and can remove as much as 20% more heat from the LEDs than the nearest competitor. This can have a big impact on the lifetime and effectiveness of the LEDs. And Nanotherm LC can be slotted into your existing production process and treated as any other MCPCB, making the transition to the most effective LED MCPCB substrate seamless.
At the chip level Nanotherm DM, our direct metalised double sided substrate material, can be used as a packaging substrate. This replaces materials such Al2O3 and AIN that either offer low thermal conductivity (Al2O3 comes in at around 30W/mK) or are very expensive (AIN).
