Definitions

  • the cross sectional profile of the reflector can be a parabolic or radial type, or simply a flat surface bent to form two wings on each side, making an angle of 30-60 degrees with the center.
  • This fixture may have a transparent cover to make it dust and water proof, but to dissipate the heat to the ambience, it can have louvers or mesh instead of transparent covers for air circulation and for protection of lamps.
  • LEDs For the purpose of bringing uniformity of light along the road multiple LEDs is used in place of T5 lamps. LEDs have definite angle of radiation of light and the luminous flux is so controlled that exactly downward light is minimized, but the light falling near the center between two consecutive poles(l) which is an angle of 20 to 60 degree from the vertical axis of pole, is maximized. This can be done without reflectors. Summary of the invention
  • the invention has been described for its use in street light, it can also be used in indoor lighting, industrial lighting and medium or high bay lightning to maximize energy by providing uniform lightning.
  • Mounting of the fixture can be pole(l) mounting, reflective surface(14) mounting, recessed mounting or screw mounting with appropriate changes in mounting facilities depending upon the application.
