Definitions

  • the present invention concerns a procedure for producing an intermediate product for lighting purposes, a semi-product for lighting purposes and equipment for producing the semi product for lighting purposes.
  • a semi-product for lighting purposes may comprise reflecting elements and possibly exterior elements such as housings, lids, etc. These semi-products comprise sub-components which, together with electrical equipment, may be assembled to form a complete fixture or lamp.
  • a fixture is to have a varied or complex surface finish, this may be fashioned, according to the prior art, by using various components which produce the desired lighting and/or aesthetic effects.
  • Figure 1 shows a substrate 10 of metal, preferably aluminium or an aluminium alloy, which is treated or coated in fields or stripes with a coating of the desired lighting character.
  • the substrate's stripes are distributed symmetrically around the centre.
  • the outer stripes 1 may be fashioned from a lacquer which produces the desired aesthetic surface finish. This may, for example, comprise a lacquer containing colour pigments. When subsequently formed, these parts will form the exterior sides of the housing or fixture.
  • the substrate may also comprise other expedient materials, for example steel or plastic materials.
  • Such fields may comprise a coating which may include lacquers with added particles which change the distribution of light.
  • lacquers with added particles which change the distribution of light.
  • transparent lacquers with different degrees of lustre from high lustre to half lustre may be used or the surface may be metallised.
  • the fields may be fashioned in different ways, for example stripe lacquering, possibly followed by metallisation or anodisation followed by stripe lacquering, stripe stamping, stripe printing or stripe lamination.
  • Another method for producing the light-distributing fields 2 may be to use stripe stamping or embossing (not shown). This method changes the surface topography and thus the lighting and aesthetic properties of the material.
  • Field 3 may comprise an area with high lustre, where, for example, the substrate material is fashioned by chemical or electrochemical brightening followed by lacquering or anodising.
  • the anodising may be performed with a well-defined oxide layer thickness, which results in a better reflectiveness than with standard anodising or lacquering.
  • the present invention is not limited to a symmetrical distribution of the stripes on the substrate or a fixed number of different stripes. It is also possible to fashion semi-products which comprise solutions in which the fields with lighting properties can be positioned in another way; this may depend, among other things, on the design of the lighting arrangement.
  • a strip substrate which is wound or on a coil (not shown) is used.
  • the process can be continuous and the strip substrate can be lengthend without stopping the process.
  • sheets may also be used as the substrate.
  • the various coatings can be fashioned and the various treatments may be applied expediently using known techniques.
  • the substrate may be subjected to treatment/coating across its entire width before the stripes are fashioned.
  • the substrate may be lacquered or anodised before the stripe lacquering.
  • the stripes may be fashioned in different operations.
  • the special aspect of the coating in accordance with the present invention is that fields of the desired width may be fashioned with different lighting and/or aesthetic properties.
  • the equipment for coating the semi-product for lighting purposes may expediently comprise a strip lacquering machine with a coating/treatment station 20 with a pick-up roller 21 which collects the lacquer from a reservoir 22 or has lacquer applied to its top and one or more rollers 23 which apply lacquer to the substrate 10 and possibly one or more transfer rollers (not shown) which are mounted between the stated rollers; the application roller(s) 23 have a width which is less than the width of the substrate.
  • the equipment may also comprise an adjustment roller 27.
  • the application roller may have milled grooves 25 so that lacquer is only applied to the substrate in the areas of the roller which do not have grooves.
  • several application rollers mounted on a joint shaft 26 can be used; the rollers are at equal distances from each other in the transverse direction.
  • the rollers may comprise means which allow them to be controlled individually with regard to direction of rotation and speed (not shown).
  • the substrate may be treated/coated on both sides.
  • a strip substrate on a coil may, in connection with the fashioning of the lighting/aesthetic properties, pass through the treatment line and be wound before being turned and passed through a new treatment.
  • the substrate may be coated on both sides in one pass through the treatment line.
  • the strip may first be treated/coated on its top in a first stage and be treated on its bottom in a second stage or vice versa.
  • the fields with different lighting/aesthetic properties must be placed on the substrate in such a way that they are in the desired location when the substrate is subsequently formed to create the intermediate product.
  • one side of the substrate may constitute the exterior of the intermediate product and be coated with a lacquer with colour pigments.
  • the other side of the substrate may be treated/coated so that fields with light-distributing and reflecting properties are fashioned in the semi-product.
  • Figure 2a shows a semi-product 14 which, in this case, has two fields 2, 3 with different light-distributing properties.
  • the semi-product shown may, for example, be mounted beside a long light source such as a fluorescent tube in a housing (dotted).
  • Figure 2b shows an equivalent semi-product 15 for use as a cross mirror or lamella. In this way, the semi-product comprising two or more lighting/aesthetic properties may be used as a reflector in a lighting product.
  • Figure 3 shows an example of forming a substrate into a semi-product which comprises both a reflector and a fixture housing. It has been shown that it is possible, using the above treatment/coating techniques, to fashion a substrate treated/coated with stripes/fields which can be exposed to fairly large stresses/deformations without the coatings cracking or the treated areas deteriorating. This produces major advantages during manufacture as the substrate can first be coated/treated and then processed/formed to the desired form at a processing station.
  • the figure illustrates, via a cross-section through the substrate, the forming of a plane substrate to create a semi-product 12 by using three forming stages, b, c and d. More than three forming stages may, naturally, be used if this is favourable.
  • the forming is performed preferably by a treated/coated substrate on a coil being fed into a roll-forming unit either directly from the surface treatment unit or after first having been wound on a coil.
  • the roll-forming unit may consist of one or more forming stages. It is expedient to use several stages which produce a gradual deformation of the substrate until the final form has been obtained. In this way, it will be possible to make semi-products from substrates which undergo major deformations in connection with the forming without the surface treatment/coating being weakened or deteriorating.
  • the substrate If the width of the substrate so allows, it is possible to fashion several sets of stripes/fields in the width of the substrate. In this case, the substrate will be split before passing into one or more roll-forming units or is possibly wound.
  • another method of forming the substrate is to cut it into the desired lengths and form it to the desired geometry in one or more stages by using known forming methods such as buckling, bending, roll-forming and deep drawing.
  • the surface treatment may be transverse to the substrate.
  • the substrate is cut transversely between each section of stripes/fields.
  • Piece-by-piece forming of these panels can then take place as stated above.
  • the application equipment may comprise rollers with grooves which run transversely to the substrate/band. It is then expedient for the stripes/fields to be fashioned by printing.
  • the mounting of the semi-product may be completed by fitting it with electrical equipment and possibly prefabricated gables.
  • the gables may be treated externally in accordance with the outer coating of the housing (for example, lacquer with pigments) and possibly internally with a light-distributing or reflecting coating.
  • the means of fastening for assembling the intermediate product and the gables and electrical equipment may expediently comprise glue, nails, screws, snap fasteners, etc.
