FR2580781A1 - IMPROVED GRID FOR ANTI-GLARE FOG LIGHT - Google Patents

Abstract

THE PERFECTED GRID ACCORDING TO THE INVENTION PLACED BETWEEN THE PARABLE AND THE DIFFUSER MIRROR OF THE HEADLIGHT, IS CONSISTING OF SPECIFICALLY COMPLIED BLADES, SUPERIMPOSED TO DEFINE A REGULAR SET 2 AND SYMMETRIC OF CELLS 3 OF WHICH EVERY ONE HAS A CONCEALER. ANTI-REFLECTIVE THAT COVERS THE INTERNAL SURFACE AS WELL AS THE EDGES AND THE SIDE FACES AND THROUGH WHICH THEY LET THE LIGHT RAYS EXCEED PARALLEL TO THE MAIN AXIS OF THE FIREPLACE, SO ELIMINATE THE SHEET AND SHEAR PROBLEM IN THE FOG.

Description

This utility model relates to a perfect grid.

  born for anti-glare fog light.

  With the fog light, excellent penetration is obtained.

  slow in the fog, directing its light beam perfectly

  and getting rid of the secondary light beam. Likewise, anti-glare provides safety at crossing

  of vehicles and more does not dazzle at the crossing.

  With the grid of the invention not only does it improve the -

  efficiency of the lighthouse by the efficiency of its light beam penetration

  but it also gives more security to drivers

  vehicles when traveling in the opposite direction, at the crossroads

  without being dazzled by these headlights.

  The fact that the light beam penetrates better into the fog

  bacon, is due to the effects produced by the grid when inserted

  between the parabola and the ray diffuser mirror.

  One of these effects is to direct the light beam by

  concentrating, and the other is due to the fact that we eliminate from the main beam

  cipal a secondary beam causing glare and loss of vision

sensitivity in fog.

  This secondary beam which is eliminated, starts from the lower edge of the parabola, from the filament and inverted prisms of the mirror, by projecting them above, illuminating the particles of fog, and consequently their reflection, which are located between the beam. principal of

  headlight and the driver's field of vision.

  By eliminating this secondary beam, the driver improves

  its visual field by not interposing between it and the main beam

  cipal of illuminated fog particles.

  The headlight is anti-glare from anywhere you are, as long as it is not the main beam, by making this advantage available to vehicles traveling in

contrary.

  The crossing of two vehicles in the opposite direction is done by

  completely safe, without any of the two conductors being dazzled,

  that, for example, a person 20 m in front of the vehicle and with the headlights on, will only see his legs lit, but looking towards the vehicle will observe only two mirrors lit with indirect light. This phenomenon also has many applications,

  but perhaps the most important for safety is that of industry

sorts automotive.

  For all that has been indicated previously with respect to anti-dazzle fog lights it was a normal headlight composed of a halogen lamp, a parabola and a mirror.

  The grid which produces said anti-glare phenomenon is

  tercale between the parabola and the mirror.

  The grid is formed as a whole of a series of openings or-

  greens from front to back through which the light emitted or directed by the dish must pass but only, and this is important, pass these beams of rays which come out parallel to the main axis of the hearth, thus eliminating the secondary iyons produced by the rays not parallel to the main axis and those also produced by

  the filament of the lamp which are all absorbed by the grid.

  The grid, overall looks like a beehive, thick-

  16 mm sor, which can adopt the most suitable shape depending on the headlight, insofar as it will in no way alter the properties described above. This thickness must take into account that it must remain in

  relationship to the length of the light beam in the area to be illuminated.

  In this hive the orifices are generally of rectangular shape.

  gular since so we use more light, and separations

  thinner which vary between 0.5 and 1 diXth of a millimeter.

  Likewise, it is certain that these orifices may have other shapes.

  mes, but we can lose brightness, usually we have to hold

  account that the best diameter is in the horizontal plane.

  The number of grid cells varies from 312 to 320 per dm2.

  It is very important that each partition of the grid or

  all its openings are covered with a black material, not reflected

  healthy, well painted, smoke black or similar, as well as the edges

  and each anterior and posterior face.

  In order to understand more easily not only the consti-

  clean tution of the grid but also its functioning, we report

  then a practical example of implementation, it being understood that the execution

  tion stated is by way of example and is in no way limitative of the invention, as shown in the accompanying drawings in which: - Figure 1 shows a perspective view of the grid; - Figure 2 shows a side elevational view of Figure 1; - Figure 3 shows a perspective view in section of the grid of Figure 1; - Figure 4 shows a perspective view of one of the cells

  which defines the grid of figure 1.

  With reference to the figures, grid 1 is shown, constituted by

  blades, preferably metallic, arranged in a niche and which define-

  feels a grid 2 which delimits the corresponding cells 3.

  Cells 3 are rectangular in shape and have a re-

  interior covering 4 based on black, smoke black or similar paint

  ble, as well as the anterior and posterior edges and faces 5.

  The blades which form the cell are joined by an element

  exterior or frame 6 which defines a grid unit.

  Having sufficiently described the nature of the invention as well as

  how to achieve it, in practice, it should be noted that the

  previously indicated positions are subject to change

  detail that does not change the fundamental principle.

Claims (4)

  1. Improved grille for anti-glare fog headlamp, of the type in which the grille is placed between the parabola and the mirror   lighthouse diffuser, characterized in that it consists of the-   mes, specially shaped, superimposed so as to define a regular and symmetrical assembly (2) of cells (3) each of which has a covering (4) based on an anti-reflective substance which covers the internal surface as well as the edges and the side faces (5); and in that, through said cells, pass only the light rays which emerge parallel to the main axis of the focal point, thereby eliminating the rays which define the secondary beam and which cause dazzling and loss of visibility in the fog . 2. Improved grid according to claim 1 characterized in that the blades are joined by an external element or frame   (6) by means of which the unit of the grid is defined.   3. Improved grid according to claim 1, characterized   in that each cell (3) has the shape of a prism of cross section tangular.   4. Improved grid according to claim 1, character-   sée in that each of the blades has a niche conformation in the longitudinal direction.
