Definitions

  • the present invention is related to the techniques used in the Electrical Industry for the design and manufacture of luminaires that are used in street lighting poles, and more particularly, it is related to a reflector for magnetic induction lamp.
  • daylight saving time which is due to the convention by which the clocks are advanced in order to take more advantage of daylight, while it is Reduces in the morning. Normally the clocks are advanced one hour in early spring and are delayed again in autumn. The addition of daylight time to the afternoon benefits trade, sports and other activities that favor the presence of light after the workday. The evening increase in light can help reduce traffic accidents, but its effects on health and the incidence of crime are less clear. It is said that by means of daylight saving time, electricity is saved by reducing the need for artificial lighting, but the evidence that supports it is weak, given that daylight saving time can stimulate the appearance of demand peaks, which increases costs.
  • Reflectors or luminaires for lamps in particular reflectors for high pressure sodium vapor lamps or metal additives with street lighting application, often consist of substantially concave shaped housing having a smooth interior reflective surface.
  • the bulb or the light source is centered as much as possible inside the reflector so that the emitted aces of light bounce mainly crosswise.
  • induction lamp technology has shown to have several advantages over the technologies described above, such as a greater number of hours of useful life, greater luminous efficiency and better luminous flux, such induction lamp technology is not It has been implemented as a technology that progressively supplants the one currently used, because the reflectors that have been used are the same reflectors designed for high pressure sodium vapor technology or metal additives.
  • the reflectors designed for high pressure sodium vapor or metal additive technology base their design described above in that the bulbs that use these technologies have a single source of almost point light. While the tubes using magnetic induction technology, have a shape that results in a light source distributed depending on the shape of the lamp in particular rather than an almost point source of light. For this reason, it is necessary to adapt the design of conventional reflectors to the shape of the tube that uses magnetic induction technology.
  • WO 2002/057685 refers to a reflector for a lighting assembly that includes a body member which defines a chamber in which a light source is distributed, preferably a plasma induction lamp having a flattened toroid shape that has an oblong opening.
  • An inner surface of the body member has a layer of a reflective material.
  • At least one wall of the body member has a discontinuity therein, typically in the form of a step, to improve the diffusion of light from the body member.
  • the reflector preferably includes means of inhibition of inter reflection that extend from the body member, in use, through the opening in the light source to reach the required light diffusion and the incandescent limit.
  • the reflector described therein presents great inconveniences, such as the fact that it is very closed (concave) and does not allow direct light to go very far, but to bounce and with low intensity; Likewise, a lot of light is wasted when using reflection mainly in a crossed way, since the more rebound the light hazez have, the more the intensity is lowered. In addition, because the surface is smooth, the light product of the reflection is more diffuse, as well as less controllable and uniform.

  • the reflector for magnetic induction lamp comprises a base structure formed by a pair of main reflector screens and a plurality of secondary reflector screens, wherein said pair of main reflector screens are joined by any means of connection.
