Philips Lumileds announces the launch of a new cool white light LuxeonK2 with TFFC (film flip-chip) LEDs. Product advancements in chips and packaging have enhanced the product's ability to perform at its highest performance in any environment.
The LuxeonK2 with TFFC technology is the only LED designed, indexed and tested for operation at 1000mA and can operate at 1500mA. Excellent optical performance, overall improvement in light output, and improved heat dissipation are all inseparable from the contribution of TFFC. Advances in packaging have further enhanced the industry's most rugged package and achieved the lowest thermal resistance (5.5°C/W) in power LEDs. The reduced thermal resistance allows LEDs to operate at higher currents, reducing Input and cost of thermal management design. The product that is binned and tested (with a minimum light output of 160 lm, 1 A drive current) has an optical output that easily exceeds 220 lm at higher drive currents. The LuxeonK2 with TFFCLED brings all the LEDs into practical use, making them stable and efficient in the toughest environments.
At rated drive currents, the LuxeonK2's power is 66% of its maximum rated power, and its performance is comparable to other single 1mm2 chips. FutureLightingSolutions currently has more than two dozen LED drivers that can deliver 1000mA or more, which allows engineers to take advantage of the high drive capability of the LuxeonK2.
Almost all power LED manufacturers have introduced 350mA products. However, at higher currents, these products cannot work stably without sacrificing lumen maintenance or junction temperature not exceeding the published maximum, nor can they work for 1A for a long time. In fact, even if the data sheet gives typical values ​​at higher currents, these values ​​cannot be achieved in practical applications.
High rated drive current is beneficial to the lighting industry. For applications such as guard lighting, road lighting, spotlights, etc. that require durability, maximum brightness, and high efficiency, the LuxeonK2 can be designed with all cost factors in mind (including thermal management systems, drive electronics, optical components, and LEDs). The most cost effective solution. Increasing the current without increasing the heat sink size or cost will ultimately reduce the cost of the fixture.
