Energy conservation is the main force driving the LED lighting market
Driving LEDs is a complex task. This is because the application of LED lighting may change. Performance parameters such as efficiency and color accuracy are greatly affected by the LED drive method. LED driving methods can affect performance, color temperature and color shift (caused by heat) and flicker effects.
Piccolo MCUs can be used in LED driver solutions, allowing designers to "further penetrate the hardware and software used in digital power control." The company's C2000 dc-dc LED lighting developer tool shows the correct power topology required to drive single or multiple shared power poles (Figure 4).
One of the main factors that prevent designers from using LEDs is how to handle the software, and the Piccolo control tool simplifies all of this. It walks you through the entire design process step by step.
Driving LEDs with high currents and low stack voltages, and meeting ENERGY STAR and Lighting Facts Label requirements as well as European standards, is a challenge. Lighting Facts Label was developed by the US Department of Energy and the Environmental Protection Agency (EPA). One countermeasure is to use fewer LED components to drive at higher currents to achieve higher levels of light output.
Using fewer LEDs means lowering product costs, but not necessarily improving the efficiency levels required by EPA. In fact, the level of efficiency tends to decline, and people noticed this in the early modification of A19 and E27 bulbs. The power efficiency level is too low.
As the output light level increases, LED drivers become more complex. According to Haitz's law, for a given wavelength of light (color), the unit lumen cost of a packaged LED is reduced by a factor of 10 every 10 years, and the amount of light produced by each LED package is increased by a factor of 20. As light output continues to increase, the effectiveness of packaged LEDs will become more limited in some applications (for residential lighting around 1 km and commercial lighting around 10 km).
While today's technology can easily meet the needs of these LEDs, in the next few years, LEDs will be limited to specific applications, and business significance is limited, unless technological innovations in LED drive technology and thermal management are greatly developed. In this regard, the solid-state lighting industry is making impressive progress, but it remains to be seen whether this trend will be maintained in the next few years.
