LED lighting market has entered a rapid growth path, such as Japan LED lighting penetration rate has reached 30%. LED lighting market today and the opportunities that the amount of general lighting, including residential 3W-15W of LED lighting, 15W-75W of commercial and decorative lighting of buildings, as well as 75W-250W LED outdoor lighting and infrastructure. Intelligent lighting the last two years will begin to grow significantly, LED Driver Solutions Sensor + + mainstream communication protocols will first emerged, lighting drive vendors are seeking to provide drivers, wireless modules, gateways, APP and other intelligent lighting platform-specific turnkey solutions to promote the rapid advent of LED intelligent lighting. In this case, the next two years LED lighting drive market and price trends show what situation? Product form and content of what will change? Mainstream supplier related dynamic and strategy is what? This paper will analyze 2014-2015 LED lighting driver market conditions in these areas.

First, the market size increases, the price pressure is still large
According to IHS report data, in 2013 the global LED driver IC total revenues of $ 1.2 billion, of which a quarter from lighting applications, estimated 2019 total output value will jump to $ 2.1 billion, while lighting driver IC output value accounted for the expanded to 43%, is the LED driver in the fastest growing fields. Lighting during driving revenue growth steadily year after year, is expected to reach $ 400 million in 2014, 2015 will increase to $ 500 million.
Play a key driver for LED lighting applications are still affected by the bulb (and lamps), flashlights, landscape lighting and other applications account for only a small market share.
The price of the LED light source is declining, in contrast drive prices have been high, the cost pressure is relatively large, the recent pressure to reduce the likelihood of this is relatively small. Is expected to last two years dimmable LED lamp driver shipped more than non-dimming driver's trends will appear. Dimmable drivers than non-dimmable expensive, but some vendors are looking for ways to narrow the gap to promote the development of tunable optical market, to obtain greater market competitiveness, dimming performance that is designed to increase the technological competitiveness instead get a higher sales price, resulting in lighting driver IC price pressures are still relatively large. 2015 dimmable driver IC prices will significantly decrease (in fact this has led to price Marvell dimming products from $ 1.5 last year dropped below $ 1, 2015 also reduced), further squeezing of non-dimming driver IC market and the price of space.
Second, 2014-2015 drive Tages: Dimming + simplifies
Lighting fixtures have been just a simple tool, but have higher demands in energy conservation, environmental atmosphere conditioning. This prompted the intelligent LED lighting driver onto the road, as well as the pursuit of more cost-effective and easier to use, it also seeks to become more streamlined.
Intelligent lighting there is no strict definition, is expected to LED driver + sensors + communication protocol is more subject to an approved manner. Dimming applications have attracted most drive manufacturers to enter, including domestic and international mainstream providers, higher dimming compatibility will be a direction drive efforts. Dimmable lighting development, currently the main obstacle is dimmer compatibility issues, both with a variety of existing dimmers technology compatibility, such as TRIAC, low voltage (0 ~ 10v) linear and PWM dimmers , also compatible with the next generation of electronic dimmers; and electronic dimmer has been proven to be more difficult than the traditional compatible TRIAC dimmer. Currently supports dimming LED driver solution performance of international vendors better, but the complex structure, the cost is relatively high, Chinese firms are seeking a breakthrough has occurred triac dimmer compatibility is higher than 90%, the price is lower than the international firms solution.
Policy standards for lighting drive performance, higher and higher requirements. Many stringent regulations around the world presented in the PFC (Power Factor Correction) and input harmonics and other requirements, such as "Energy Star" requirements for LED lighting adjustable down to the metering of 10%, "Energy Star" and "European power manufacturers Association" (IEC 61000-3-2) require residential lighting power factor greater than 0.7, commercial lighting, power factor greater than 0.9. Maintaining overall performance while controlling costs is no easy task, lighting driver suppliers will tend to adopt a more optimized circuit design, eliminating additional discrete components to reduce costs. Small size, high PF, no flicker, good single-stage dimmer compatibility drives may soon come out, there are already some manufacturers have made ​​a plan.
