China National North Car Group Co., Ltd. recently released in Xi'an: High-power IGBT chips (insulated gate bipolar transistors) were identified by experts and put into mass production. Since then, China has completely independent proprietary high-power IGBT "Chinese core." According to reports, as a new generation of semiconductor devices, IGBT is a key core component of automatic control and power conversion, and is widely used in the rail transit equipment industry, power systems, industrial frequency conversion, wind power, solar energy, electric vehicles and household appliances industries.
Previously, domestic high-end IGBT chips basically relied on imports. The successful development of this high-power IGBT chip will not only provide a strong "Chinese core" for China's high-speed rail, EMU and other rail transit equipment and other related industries, but will also gradually improve the status of all domestic high-power IGBTs that rely on imports and reduce them. The cost of rail transit development in China. At present, China has become the world's largest consumer of IGBT chips, with annual demand exceeding 7.5 billion yuan, and growing at a rate of more than 30% per year. By 2020, China's rail transit electric traction industry will not have an annual IGBT chip market size. Below 1 billion yuan, the smart grid is no less than 400 million yuan. According to reports, together with CNR, there are currently only four companies in the world that have mastered this technology.
MR11 4w DIM led Spot Light is lighting with the size of the cup.
Spotlights lights Cup MR16 and MR11 are divided into two, the former is the headlight cup, which is a small lamp cup
MR11 4w DIM Led Spot Light Cup points not connected with 12V and 220V transformer transformer, such as you are, then spotlights with transformer.
What you need is 12V 35W MR11 halogen lamp cup.
Lampholder two pins at different distances, MR11 4w DIM led Spot Light feet away from the common general 4mm; MR16 lamp pin pitch is generally 5.3. Some lamp base jacks are oval, light bulbs foot distance 4,5.3,6.35 apply; some lampholder socket is circular, applies only to one kind of bulb from the feet.
