PHILPS Lumileds company launched the industry's first 1 LED--LUXEON (R) K2

Philips LumiLEDs announced the launch of TFFC (thin film flip) LED new cold white Luxeon K2 products. Advances in chips and packages have enhanced the ability of products to exhibit the highest performance in any environment.

TFFC technology using Luxeon K2 is unique, designed specifically for the 1000mA under the work of design, classification and testing of LED, and can work under 1500mA. Excellent optical performance, the overall improvement of light output and the improvement of heat dissipation are inseparable from the contribution of TFFC. The progress of the packaging industry is already the most durable package has been further improved, and the thermal resistance in power LED in the lowest (5.5 degrees /W), the thermal resistance decreased LED can work at higher current, lower heat input and cost management design. Through the test and test of the product (light output is 160lm, 1A drive current) its light output in higher drive current is easy to exceed 220lm. The use of TFFC LED Luxeon K2 all the LED into practical application, so that it can work in the most severe environment and maintain high efficiency.

At rated drive current, the power of the Luxeon K2 is 66% of the maximum rated power, and its performance is comparable to that of other single 1mm2 chips. Future Lighting Solutions currently available for more than two dozen 1000mA or even higher current LED driver, which enables engineers to Luxeon K2 high drive capability to take advantage of.

At present, almost all power LED manufacturers have launched 350mA products. However, under higher current, these products are not able to work without sacrificing the lumen retention rate or junction temperature does not exceed the maximum published in the case of stable work, can not work under 1A. In fact, even if the data table gives a typical value of higher current, these values can not be achieved in practical applications.

High rated drive current is advantageous for the control group. The application of requirements like lighting, road lighting, guard spotlights, durable, maximum brightness and high-efficiency, taking into account all the factors in the cost (including heat management system, driving electronic components, optical components and LED etc.), the use of Luxeon K2 to design the solution cost efficiency. Increasing the current without increasing the size or cost of the heatsink will eventually reduce the cost of the lamp.
