  • Buck Configuration High-Power LED Driver
    The circuit and firmware described in this application note demonstrates a minimal parts count driver/controller for a high-power (1W or greater) LED. The circuit is based on a buck topology switching power supply using the on-chip comparator peripheral within the PIC12F675 PIC(R) microcontroller
  • LED Lighting Case Study (.pdf)
    A luxury hotel in South-West England decided to replace the 35W halogen downlights in the corridors, bedrooms and lobby areas with our replacement GU10 lamps which consume only 3.7W each, in an effort to reduce their carbon footprint and reduce their high electricity bills.
  • Raw vs. Effective Lumens
    LED lamp output values (Lumens) can vary dramatically depending on which values are being quoted. The following information may assist selecting the right product for the right application. There are inherent losses associated with any lamp (LED, Halogen, HID or Incandescent). The main losses
  • Green Energy and CAST Lighting
    Lamps. Bright light LED's are highly susceptible to heat. Various municipalities may impose a limitation on. damage. Exposure of the LED to temperatures. lamp lumen output. a few degrees above specifications results in. a dramatic degradation of life. For this reason,. 10 watt: 120 lumens. luminaires

  • Guide to Choosing the Right Light
    ?. Is the extraordinary bulb life and reliability of an LED needed or is the blinding power of a halogen or xenon bulb critical?. BATTERY TYPE?. Can the budget pay for disposable batteries or does frequent use demand rechargeables?. Disposable or Rechargeable?. Disposable batteries, either alkaline or lithium, have
  • Star Ceilings 101
    end of the fiber is collected in a common input, terminated, and inserted into a light source. The light source is placed in the ceiling or in a nearby closet. LED, Quartz halogen, and HID light sources are typical light sources for star ceilings. As the star field technique gained notoriety
