Definitions

  • the present invention relates to a reflector comprising of multiple reflecting surfaces which increase the illumination level while decreasing energy consumption in usage areas with high energy consumption for illumination.
  • the aim of the invention is to provide the refraction and reflection of light in the right manner to achieve homogenous and efficient illumination.
  • the invention relates to a reflector comprising of several reflecting surfaces that would increase the level of illumination with low energy consumption and cost particularly in outdoor and high-ceiling illuminations. Achieving energy efficiency is aimed in such areas as ports, airports, stadiums, tunnels, motorways, industrial facilities that necessitate illumination from a high ceiling, logistics facilities, hangars, factories and the like with the use of the product that is the subject matter of this invention.
  • illumination can also be referred to as the amount of light hitting a surface.
  • the invention that is the subject matter of the application TR 2005/02979 includes identically sized embossments that are lined next to each other and having square cross-sections on a circular reflector surface.
  • the purpose here is that light rays emitted by the source will be reflected by the dome-shaped structure on the upper surfaces of embossments.
  • embossments that are placed on a circular sheet cannot reflect the light with the desired intensity, nor can the reflected light can be utilized with desired angles.
  • Another disadvantage of said invention is that shadows are formed on the illuminated surfaces due to the reflector structure.
  • reflection of the light source is split into many light points which leads to the situation referred to as glare. This situation is observed particularly in the types of lighting systems described in documents EP0735311 A1 or EP0479042 A2. Since components of the reflectors are designed to deflect or expand the light beam, these are formed by convex or concave mirror components that do not have any discontinuities on their surfaces.
  • TR 2011/07604 describes an armature reflector having a white coating. Said reflector's surface that is facing the light source is covered with a coating that is formed with resins that provide specific colors and that contain light reflecting pigments. Using various coatings in the reflector structure increases the cost while also failing to provide the desired efficiency in the reflection factor. In addition, the reflector that is the subject matter of said application refracts light inefficiently due to its planar surface.
  • the product that is the subject matter of the application DE 4406458 A1 is an example for reflectors having a domed upper surface. It is stated in this document that reflecting components are made of light expanding material and that they have a domed upper surface, as well as a planar bottom surface that is coated with a reflecting layer. Another improvement in the said field is described in document DE 2535174 A1, where certain light spectrum bands are developed to be used in conjunction with known light sources. Said reflector surface is coated with a protective layer and thus manufacturing costs are increased.
  • Coatings help mix the interference colors of the layers to achieve white light and they also help include the rays that create undesired effects in scattered light.
  • a known disadvantage of such reflectors is that they reflect undesired spectral units such as infrared radiation into the environment. In addition to that, they are also harder to manufacture.
  • reflecting plates are made of high-grade aluminum and fashioned as flat panels, whereas they can also be given concave or convex shapes per demand.
  • the invention relates to a reflector (3) that would be used in industrial facilities that require usage of high energy for illumination, logistics facilities, hangars and factories, and that would decrease energy consumption and thus cost while increasing the level of illumination.
  • the invention that is the subject matter of the application aims to provide solutions to problems in the current state of the art.
  • the subject matter of this application which, in particular, relates to illumination armatures used outdoors the reflecting surface of a reflector (3) is partitioned into several smaller sections that possess certain reflecting characteristics. In this way, reflection characteristics that cannot be achieved or can very hardly be achieved with a smooth surface are aimed to be achieved.
  • FIG 1 which is provided to describe the reflector (3) that is the subject matter of the invention in more detail depicts an armature structure in a transparent fashion.
  • a ballast box (1) and an external case (4) are present at the very top.
  • the ballast box (1) is a circuit component that creates high voltage during at the starting of the operation and constrains the current afterwards.
  • a reflector (3) is placed inside the external case (4) and a light source (2) is placed inside the reflector (3).
  • the reflector (3) that is the subject matter of the invention has a circular rotating paraboloid shape with a generally upward facing peak. Thus the interior region of this paraboloid is suitable to house a light source (2). Light rays emitted by the light source (2) are reflected by the reflector (3) that is the subject matter of this invention.
  • the exterior case (4) is preferably made of aluminum and scatters the rays reflected by the reflector (3) without losing efficiency.
  • the reflector (3) is essentially composed of several reflecting surfaces that can have concave, convex, or planar structure.
  • the desired reflector body that has a one-piece or integral structure is formed by cutting or bending a metal plate that is preferably made of high-grade aluminum.
  • the reflector (3) can generally have a circular rotating paraboloid shape, it has a three dimensional structure that allows the formation of a rotational paraboloid shape when its exterior rings are brought together, as can be seen in more detail in Figures 2 and 3. It is composed of a base segment (5) and side segments (6). Side segments (6) can be of any geometric shape, but each are preferably composed of reflecting surface components that have an isosceles trapezoid shape.
  • the reflector (3) includes a skirt (9) and peak (8) sections.
  • the sides of the isosceles trapezoids that are parallel to each other get shorter along as moved from the skirt (9) portion to the peak section (8).
  • the shortening sides of the isosceles trapezoids intersect at on a base segment (5) of the peak section (8).
  • the reflector (3) has an inner and an outer circumference that are concentrically centered on an axis that extends toward the floor from the peak section(8) of the reflector (3).
  • the reflector (3) preferably has an axially symmetrical structure. Size, dimension and layout of the reflecting surface units that make up the side segments (6) can be adjusted in accordance with demand.
  • the reflector (3) can be adjusted to include an assembly wing (7) at its skirt (9) section so as to be accommodated to the lighting device structure.
  • the reflector (3) that is the subject matter of the invention is characterized by its comprising of preferably a polygonal peak section (8) for the light source (2) to be attached and base segments (5) that are made of a preferably polygonal skirt (9) that provides an opening for the light to be emitted through; an interior region to house the light source (2); and a reflecting body that is configured in the form of rotational paraboloid form, which has many radial side segments (6) that are made of reflecting surfaces laid out one after the other.
  • the reflecting body is comprised of polygonal base segments (5) that are laid out concentrically, one after the other, such that they would form a rotational paraboloid form whose external circles are rotating.
  • the reflecting body is generally axially symmetrical.
  • Reflecting surface units preferably have isosceles trapezoidal form.
  • Base segments (5) preferably have isosceles polygonal form.
  • Base segments (5) are configured such that their diameters would increase, moving from the peak section (8) toward the skirt (9).

  • Base segments (5) are preferably of polygon shape having 3 to 16 sides.
  • Width of the edges that make ups the reflecting surfaces are preferably between 5mm and 80mm.
  • materials with high coefficients of reflection are preferred to achieve maximum efficiency in the usage of the light source (2). Further, properties like corrosion resistance and ease of shaping or processing flexibility of the material used are of importance with regard to creating durable products.
