Bulbs, flat lamps into hot non-isolated solutions increasingly rich

With the increasing awareness of energy saving and environmental protection, the global phase-out of incandescent lamps significantly accelerated the pace. LED era has completely come to replace the traditional light source. It is estimated that the global LED lighting market will grow 90% this year. In the overall favorable policy environment, the future of domestic LED lighting is also much optimistic about the prospects. As the main production base of global LED lighting, China’s LED lighting market will usher in explosive growth. LED lighting market for the development of the situation and intelligent control, dimming and other hot topics, the reporter interviewed the core friend Microelectronics, Dr. Yi Yangbo, vice president, and understand core friends Peng LED driver IC on the latest products and technologies.

Global LED lighting market size

According to “China’s roadmap for phase-out of incandescent lamps”, China will ban the import and sale of incandescent lamps for general lighting of 60W and above starting October 1 this year, which will prompt the outbreak of LED lighting in the field of home lighting. Dr. Yi believes that this year’s LED lighting market is expected to be more rational and faster than the first half of 2013 to extend from commercial to home lighting, including the domestic home market will grow very rapidly. The 3-8W LED bulb replacement market and 12-40W LED ultra-thin panel light are hot. “There are two market trends to come to mind in 2014. The first is the rapidly growing demand for flat panel light bulbs and the second is the rapid transition from bulbs to non-isolated architectures.”

For these LED lighting market trends, core friend Microelectronics introduced a full range of non-isolated products to meet market demand. Dr. Yi introduced to reporters, LED flat panel lamp driver IC development, core friends Microelectronics 12-41W non-isolated driver chip PN831X series of built-in MOS focus on how to solve the more powerful 24-40W BOM program to do more streamlined , Program costs dropped significantly. The biggest difficulty for the bulb driver IC is to make the increasingly sophisticated 5-12W program to be more perfect, core friend Microelectronics introduced PN1231X / 833X non-isolated step-down driver IC series 3-12W, valley filling PFC and APFC optional , Reduce BOM, increase protection. Especially for the recent hot filament bulb also introduced a series of very small size solutions.

SCR dimming will eventually eliminate digital smart dimming will emerge

LED lighting market gradually expanded, but also led the intelligent control and dimming and other markets. Dr. Yi believes that intelligent control is still in its infancy, the current focus is to foster customer needs. “We are going to have some advanced LED drivers integrated with digital control being developed and will support smartphone APP control in the future, and now Core Microelectronics is working with its customers to define and develop new products.” In addition, he said LED Dimming market is currently mainly concentrated in North America and other regions of the controllable dimming alternative applications, “We think SCR long-term view is going downhill, the next one or two years, digital intelligent dimming will emerge, will be Lighting atmosphere designers to provide a broad useless, but also will further expand the LED lighting market for home and commercial applications, which is the core of the next microelectronics LED lighting in the field of next place of concern.

Reliability Technology reserves rich

At present, the development of LED lighting has gradually been gradually transition from the early disorder to a more standardized stage, and LED lighting to enhance one of the bottlenecks is still the driving power supply. Dr. Yi said that as a leading manufacturer of power chips for home appliances, core friends Microelectronics has accumulated many years of experience in professional power IC design under high temperature and high humidity environment. “We think that to improve the IC cost-effective should start from two aspects, first, the power supply program to reduce the number of external components, each component means some inherent failure rate, reducing components is to improve reliability; the second is to provide more intelligent and powerful protection IC Function, so that components in the processing link Weld / tin does not cause physical damage to the IC, so that the use of environmental degradation encountered in the Department can start a reasonable protection to avoid dead lights. Core friend microelectronics in this area is rich in technical reserves, compared to other Only LED-driven manufacturers involved more adequate. “Looking to the future of the domestic lighting market, LED lamps market penetration will continue to rise. With the growth of technical strength, the domestic driver IC products gradually close to the technological level of international giant enterprises, cost-effective will also continue to increase.
