Power Integrations has announced an ultra-small power product reference design kit (RDK-131). It helps engineers design high-efficiency LED power supplies to replace energy-consuming incandescent lamps. The kit also provides designers with a power supply circuit that can be placed in an LED bulb socket and ensures LED bulb power for replacing incandescent lamps. The product meets the requirements of electromagnetic compatibility standards.
Unlike incandescent lamps, which can be powered directly from the grid, each LED bulb requires a power supply built into its screw (E27) or bayonet (GU10) socket.
"Making a power circuit that fits into such a small space is not an easy task, especially if you need to effectively suppress electromagnetic interference to meet test standards. To solve this thorny application problem, Power Integrations has introduced a volume. The smaller SO-8 seal is a sigh of apology. The ICs LinkSwitch-TN product line. The reference design kit RDK-131 with this device includes a tested power supply sample, blank PCB , LinkSwitch-TN samples and design guidelines for designing LED lighting equipment using our ICs. This reference design kit greatly simplifies the design of LED lighting equipment and speeds time to market." PI is in charge of AC-DC products. Don Ashley, Marketing Manager.
Because the thermal effects of power generation account for 40% of the total global greenhouse gas emissions, relevant regulatory agencies and governments around the world are looking for ways to reduce energy consumption. For example, in a recent parliamentary debate (Reuters/Yahoo Wednesday, January 31, 2007), California Rep. Lloyd Levine commented: "The incandescent lamp was developed and used in about 125 years, and its efficiency is extremely low. Only five percent of the electricity consumed is converted into light." If his proposal - 'How many members of the House of Representatives are required to change the light bulb bill,' passed, California will ban the use of incandescent lamps from 2012 . In sharp contrast to incandescent lamps, LED bulbs consume only one-third of the electricity consumed by incandescent lamps and have a longer life.
The RDK-131 is priced at $100.00 and can be purchased today at
