Approximately 21% of the world’s electrical energy is used for lighting. That equals a whopping 12 billion kWh per day. Other household appliances, such as washing machines, dishwashers and air conditioning systems further overload the demand for electricity. 

• LED lighting: ZMDI LED drivers are part of the solution for efficient street lamps, household and office light fixtures.  Our customers can build lighting products with reduced energy consumption compared to traditional light bulbs and halogen lamps. ZMDI LED-Drivers
• White Goods: Precise sensor signal conditioning in white goods, such as washing machines and dishwashers, optimizes their control functions and increases their energy efficiency.  This is especially important to manufacturers earning the EU CECED energy label and the United States Energy Star® label. ZMDI supports these initiatives with a complete line of low-power sensor signal conditioner chips that measure water levels and water quality, as well as angle and temperature. Better measurement equals superior performance. ZMDI Sensor Signal Conditioner
