With intelligent automatic design tools , manufacturers will be able to quickly develop highly LED Bulb customized lighting solutions to meet each customer's individual needs. In this lighting is no longer a one-time items , but the sustainable use of more than a decade of the new business model , the rich beauty of the light source can be embedded in commercial or industrial buildings walls , or embedded within residential furniture , and they will serve as electrical sales, building or residential renovation in the transformation of the former has been used .
To achieve this goal, designers must take a systematic approach to design. The first generation LED lighting systems that appear premature failure has proved one thing: the life of any LED lighting products have the shortest working life depends on individual components.
Despite the usual LED circuit can meet Energy Star SSL V 1.1 L70 prescribed approximately 45,000 hours of work life requirements, but for the common two power circuits of the life cycle of only 20,000 hours. In fact, the power supply design weaknesses undermine long-life LED technology advantage and high ROI.
Eliminate failure points
Why should we do ? Today, many of the LED lighting systems typically use a two-stage power supply , this power supply will be used to improve the power factor of the first stage boost converter and the second high-pressure DC-DC converter is combined together . These power supplies are the most common point of failure for the two large-capacity storage between the electrolytic capacitors.
