Seoul Semi improves LED architecture

Seoul Semiconductor has announced an innovative LED chip design that allows significantly improves the light yield at high operating temperatures. The new architecture will be rolled out soon, the company said.


The first product family which will benefit from the new technology will be the company's Z5 platform, an industry standard format covering the power spectrum from 1 W to 3 W. The company plans to use the new technology to cover the entire color spectrum from 2600 K through 7000 K. The first product scheduled to be based on the new architecture will be the Z5P which features a maximum luminous flux of up to 140 lm/W and a maximum brightness of 133 lm at a junction layer temperature of 100 °C. The device will be characterized by a low thermal resistance of only 6 degrees per watt.

Seoul Semiconductor Managing Director Manuel Zarauza called the new technology "a huge leap forward" and said the entire lighting industry would benefit from the move. The company however did not provide details of the new chip design.

Seoul Semiconductor plans to use the chip technology not only for the Z5 platform but also for other product families and introduce these products during the course of the months to come. In 2012, the company will roll out a number of LEDs based on the new chip technology.

The SoCKIT evaluation kit is Arrow's latest development tool, featuring an Altera Cyclone V SoC with a dual-core ARM Cortex-A9 MPCore processor integrated within its 28nm FPGA fabric.

Altera SoCs allow embedded system developers to differentiate their end product with customized hardware and software, and extend the product lifecycle through hardware and software updates in the field. This month, Arrow Electronics is giving away five SoCKIT evaluation kits featuring Altera’s ARM-Based SoCs, worth €249 each, together with the free entrance to one of Arrow’s SoC workshops organized throughout Europe.


And the winners are...

In our previous reader offer, Freescale Semiconductor was giving away five IMX6Q, Sabre-lite kits, worth £128.06 each.

Lucky winners include Mr. X. Salada Sole from the UK, Mrs A. Peric from Germany, Mr Z. Janosy from Hungary, Mr D. Gacina from Croatia and Mr B. Boris from France. All should be receiving their packages soon. Let's wish them some interesting findings with their projects.
