  • Green Energy and CAST Lighting
    the following criteria: (These points are. discussed in detail later in this document.). Adherence to energy efficient low voltage (12-volt) lighting. Selection of lamps with highest possible lumen efficacy (lumens/. watts). Selection of lamps with longest possible life. Luminaire design to maximize
  • Offline LED Driver Intended for ENERGY STAR(R) Residential LED Luminaire Applications
    of the typical products in this category. include portable desk lamps, under-cabinet lights, and. outdoor porch lights. One of the most common power supply topologies for low. power offline LED drivers is an isolated flyback topology. Unfortunately standard design techniques used
  • Solar LED Lamp Application Using the CAT4139
    sources. In. a variety of renewable energies, solar energy is one of the. most attractive selections together with high power. light-emitting diodes (LED). LED lighting for the future. development is the trend, which has several advantages,. such as low power consumption, long life, fast response
  • IR Survey Pinpoints Air-Curtains Heat Distribution Problems and Slashes $34,000 from New Jersey Bulk Mail Center Utility Bill
    is housed in an outdoor. switchgear cubicle. The low voltage distribution system is comprised of eight double-ended, 4160-480/277 V -. 1000-1500 kVA transformers, with main, tie, and subfeeder breakers. These subfeeder breakers provide. power to various power, lighting, receptacle panels, motor control
  • Solar Loading Effects on TFT Displays Part I
    temperatures are. cooler and the sun is low in the sky. However, for those installations located in the more northern. latitudes nearly 80% of the maximum absorbed power occurs during the summer months when ambient. temperatures are high. Heating from the Backlight and Electronics: TFT LCD displays
  • Using Power Resistors as Heaters
    Power resistors and resistance heaters share many common design considerations. In both products, good thermal design ensures low thermal resistance between the element and the exterior environment. Both must be rugged and reliable. Power resistors are often used in heater applications. They allow
  • Choosing Data Loggers for Your Green Building Project
    to single-family homes, measurements of conditions such as temperature, solar radiation, and energy consumption are essential to carrying out and testing your designs. Today's data loggers are small, low-cost, rugged devices that record unattended indoor and outdoor measurements at user-specified intervals 24
