With the LED industry IS gradually pick up in 2013 , LED lighting in commercial establishments, outdoor lights and other areas are showing vigorous growth. Around the further application of LED lighting in the driver IC, light, packaging, lighting design and other main areas, many industry manufacturers will more energy efficient, and cost-effective solutions for better placed in the most important position on technology development. Articles recently interviewed global LED driver IC, the world leader - PowerIntegrations company (abbreviated PI), senior product marketing manager AndrewSmith, ask him to introduce the current LED driver IC in the market demand, the development trend of technology development, as well as PI In product development on the latest situation.Into mid-2013, recalled the first half of LED lighting market trends, whether or straight-shaped lamp LED bulbs and other products, the price are about 20% of the rapid decline, especially in the field of commercial lighting, LED lamps Price has taken the lead hit the "sweet spot", which also stimulates the year LED lamps in the commercial lighting market penetration efforts. Face a new round of market growth opportunities, urgently requires LED lighting solutions can further improve the overall efficiency, while improving cost effectiveness, to accommodate the LED lighting in the larger universal application.Especially in LED lighting core - Power driver IC side, although in recent years the average selling price of LED lamps continued to decline, but the drive down the cost of space is not large, this situation is expected to change in the near future. According to a survey IMSResearch to 2013, driver IC continues to occupy 40% of the manufacturing cost of LED bulbs, but with the decline in the price as well as the overall lighting from the parts of the upgrading of technology, is expected to cost ratio LED driver will dramatically before 2015 down 36%.Smith pointed out that the driver IC cost reduction is the trend, which requires manufacturers through the manufacturing process improvements, innovation driven program, and keep lighting power supply design of the latest developments, to develop cost-effective drive to keep the cost curve. For example, the current market trend is a more obvious: including candle lights, A19 bulbs, GU10, PAR30/38 spotlights, etc., different types of LED lights are beginning to increasingly using non-isolated power supply topologies (particularly in small and medium power lighting applications). Compared with isolated power supply design, non-isolated topology design and circuit board layout is simple, small board size, energy efficiency is also higher, and thus the manufacturing cost (Cost), space (Space), and energy-efficient performance (Efficiency), etc. all have obvious advantages, the current development trend of this product in Europe and other major markets LED lighting applications have been generally recognized.In this trend, Smith believes that as the market for LED lighting drive power in terms of cost, size and energy efficiency put forward higher requirements, LED driver IC will also be moving in the direction of a higher degree of integration in the internal integration of more components / functions (such as dimming / non-dimming etc.), as far as possible simplify the manufacturers in the development brought about when the external design (eg thermal, etc.) and the wiring costs and ultimately help increase the drive power cost.
