250 million investment item, LED lighting manufacturers has been finished and put into work on January this year. Changzhi was listed on the list of the first top 100 enterprise in shangxi province on May this year. The purchase contract of core equipment MOCVD was signed smoothly on June. As a result, changzhi city’s LED lights PV industry facility can match with international first-class PV enterprises. It is just spend more than one year, changzhi electronic industry park intergrate industry cluster has hit on the express develop road and obvious achievement has got on industry structure adjustment.

With the guideline of sicentific outlook on development, changzhi city, Shanxi province tightly catch the opportunity of develop low carbon economy, target at transformation development, pushing industrial structure adjustment, conceration on develop hi-tech PV industry chain and building industry cluster in the way of vertical integration.

PI introduced for the introduction of LED lighting lamp T8 ballast reference designs

LinkSwitch-PH LED Driver IC to meet the PF and THD specifications, efficiency of 91%; specifically designed for commercial and industrial lighting

San Jose, California, USA, August 24, 2011 (Reuters) - for general lighting of the LED driver IC, a leader in the field of Power Integrations, Inc. (NASDAQ: POWI) today announced the release of a new 25 W LED T8 tube Ballast Power supply reference design. The design (DER-287) The most striking is that over 91% efficiency, achieve industry-leading level, while the power factor (PF greater than 0.9) and harmonic distortion (EN61000-3-2 Class C) in meet commercial requirements. DER-287 is used Link Switch-PH Series LED driver IC designed for single-stage one LNK409EG converter. Single-stage technology by eliminating the conventional two-stage design used in lightI solator And large aluminum electrolytic capacitors can be significantly extended product life.

Power Integrations, product marketing manager Andrew Smith said: "In light of the overall increase lighting efficiency and achieve high power conversion efficiency and LED options are equally important, if not a single-stage topology, in the narrow space of the T8 lamps a cost-effective way to make more than 88% efficiency is extremely difficult to do, while the efficiency of this design is easily more than 91%. "Smith added:" Most areas require commercial and industrial lighting products must have low THD or high-PF - LinkSwitch-PH LED driver IC can easily meet this specification, so that the final design for the global market. For more information see the report of this new design paradigm. "

In addition to using the controller, drives and switching MOSFET also integrated into a single package within a highly integrated single-chip design outside, Power Integrations' Link Switch-PH product line also includes thermal protection and overcurrent protection with the many protection features including. This means that only requires minimal external components to achieve the design - This compact space of the T8 lamp is extremely important.
