Abstract

A method of placing of a lighting, signalling and information device into the glass of a vehicle window consisting of a (reflexive or transmission) transparent optical grid, a light guide and a light source, the optical grid (2) functioning as a light active surface of a lighting or signalling device or an information device is placed between the layers (6) of a plastic and/or between the outside (4) and the inner (5) glass layers, where a light beam (9) is brought in by a flat light guide (3) to a reflexive transparent or a reflexive or transmission transparent optical grid (2) which is placed on the inner side of said front and/or rear/side window glass (1 fig 1a) of a vehicle cab.

Description

Field of the Invention The present invention relates to a method of setting

  in place of a lighting, signaling and information device in the glass of a windshield and / or rear window glass of a vehicle, this device consisting of a transparent optical grid , a light guide

and a light source.

  Thus, the present invention relates to a method

  installation of a transparent optical grid for

  bending capable of deriving from the light energy introduced

  in a light guide, to send it in a direction

  tion and dimension required in the glass of a windshield and / or rear window glass of a vehicle cabin, in order to produce lighting in front of or behind it, to form a signal or to put in place a transparent optical grid capable of reflecting or refracting light coming from the outside, to present information, or for aesthetic purposes, between plates

  individual glass of flaky ice cream.

  Background of the invention Lighting and signaling devices

  of a vehicle are usually placed in places where

  served where their body occupies a certain place. In the case of central light sources in a vehicle, the light is brought by light guides to lamps, and it is finally directed by means of optical devices. The

  known solutions use the glass thickness of the

  clear rear of the vehicle to distribute the light energy coming from a light source, and a connection corner to

  a holographic grid placed on the rear window of the vehicle

  here to play the role of a lighting surface.

Summary of the invention

  The proposed method of setting up a device

  tif lighting, signaling and information in the glass of a windshield and / or rear window glass

  of a vehicle cabin, consists of placing an opti-

  transparent reflection or transmission in the glass, while bringing a beam of light by a guide of Il i 1ii11 1i11 1 flat light forming part thereof, between a glass and

  a layer of plastic or between two layers of ma-

  plastic in the case of a transparent optical grid for reflection, so that the layers of glass with the transparent optical grid inserted therein are definitively joined together by a subsequent technological process. Properties of the transparent optical grid

  of reflection or transmission thus inserted are not in-

fluenced by this operation.

  To this end, the present invention relates to a

  process of the above type characterized in that the grid op-

  transparent reflection or transmission tick, serving as an active light surface for a lighting or signaling device or an information device, is placed between layers of plastic material and / or between the outer glass layer and the inner glass layer, while a light beam is brought by a flat light guide to a transparent optical reflection grid or to a transparent optical reflection or transmission grid which is placed on the inside of the glass of the barrier -broken

  and / or the rear window of a vehicle cabin.

  Executing the optical grid in transparent form prevents any shadow projection or distortion of the situation outside the vehicle. As a source of energy

  luminous which satisfies the lighting device or

  generalization thus set up, one can use a bulb, a discharge lamp or the necessary quantity of light-emitting diodes (LED). In the case of the insertion of a transparent optical reflection or transmission grid

  for information or aesthetic application, energy lu-

  outdoor miner from an artificial light source

  sky or natural serves as a light source. The present lighting, signaling or information device, for example for a vehicle, uses the glass surfaces

  existing vehicle, causes absolutely no distortion

  properties of the glass during its operation and inactivity, while the light energy source does not need to be in the immediate vicinity of the surface

  optically active lighting or signaling. Brief description of the drawings
