Power Integrations has introduced an ultra-small power supply reference design tool (RDK-131) to help designers develop high-performance LED alternatives to replace high-power incandescent lamps. The tools developed to help designers to meet the power supply circuit led bulb socket, while ensuring to replace incandescent lamp led by electromagnetic compatibility and electromagnetic radiation noise tolerance and the like (EMC) requirements.
Unlike incandescent sources that can be powered directly from utility power, each LED bulb must have a power supply installed in an Edison (E27) or Bayo net (GU10) outlet.
Don Ashley, product marketing manager for Power Integrations AC/DC, said: "It is not easy to develop a power supply circuit that can be used in such a small space, especially when electromagnetic interference is reduced to meet current standards. In order to respond to such applications. Volume limitations, Power Integrations has introduced the l inkSwitch-TN series of non-isolated offline switch components in a small SO-8 package. Our reference design tool 131 not only integrates this component into a tested and functioning power supply. The board is supplied with an additional blank board, additional l inkSwitch-TN sample components, and instructions on how to design LED lighting power supplies using our components. This set of tools greatly simplifies the LED light source design process and speeds up Its time to market."
Since power generation accounts for about 40% of greenhouse gas emissions, governments and government agencies around the world are looking for ways to reduce energy waste. For example, California State Councilman Lloyd Levine recently pointed out: "The incandescent bulb has been inefficient since it was invented and used 125 years ago, and can only convert 5% of the electricity received into light." Once the "How Many Legislators Does it Take to Change a Lightbulb Act" is passed, California will disable incandescent bulbs from 2012.
In contrast, LED bulbs consume only one-third of the power of incandescent lamps and have a longer life cycle.

The biggest feature of the temperature regulating valve is that it only needs an ordinary 220V power supply and uses the energy of the regulated medium to directly automatically regulate and control the temperature of steam, hot water, hot oil and gas. It can also be used to prevent overheating or heat exchange. The valve has the advantages of simple structure, convenient operation, wide temperature regulation range, fast response time and reliable sealing performance, It can be adjusted at will during operation, so it is widely used in hot water supply in chemical industry, petroleum, food, light textile, hotels and restaurants.
