Description
Signalleuchte, insbesondere für Fahrzeuge Bekanntlich dürfen Signalleuchten nicht unter von außen einfallendem Fremdlicht, sondern nur unter dem Eigenlicht in der Signalfarbe aufleuchten. Es ist bekannt, zur Erfüllung dieser Forderung die vom Eigenlicht der Leuchte durchstrahlte Lichtaustrittsscheibe oder -haube auf der Innenseite zu mattieren und mit einem reflektierenden Belag zu versehen. Die Mattierung wurde durch mechanisches Aufrauhen, z. B. mittels Sandstrahles, erzeugt. Dieses führt zu einer ziemlich groben und scharfen Oberflächengliederung, die sich schlecht für das Aufbringen eines Spiegelbelages eignet, und zwar die Reflexion von Außenlicht genügend dämpft, aber auch das Durchfallen von Eigenlicht erheblich beeinträchtigt.Signal lights, especially for vehicles It is well known that signal lights are allowed not under external light coming in from the outside, but only under its own light light up in the signal color. It is known to meet this requirement The light exit disc or hood on the To matt the inside and to provide a reflective coating. The matting was made by mechanical roughening, e.g. B. by means of sandblasting. This results in a fairly coarse and sharp surface structure that looks bad suitable for the application of a mirror covering, namely the reflection of outside light attenuates enough, but also significantly impairs the falling through of natural light.
Man hat auch schon dünne innere Metallspiegelbeläge verwendet, die den Durchfall von Eigenlicht nach außen noch zuließen, aber das Einfallen von Außenlicht durch dessen Reflexion an der Glasauflagefläche verhinderten. Dabei ergeben sich jedoch zu scharfe, blendende Reflexe.Thin inner metal mirror coatings have also been used still allowed the diarrhea of natural light to the outside, but the incursion of outside light prevented by its reflection on the glass support surface. This results but too sharp, blinding reflexes.
Eine ebenfalls vorgesehene bloße Mattierung der Scheibe verhindert nicht das Einfallen von Außenlicht und kann zu Fehlanzeigen führen.A mere matting of the pane, which is also provided, is prevented does not prevent the incidence of outside light and can lead to incorrect displays.
Eine völlig einwandfreie Wirkung wird erfindungsgemäß dadurch erreicht, daß die Mattierung durch ätzen und der reflektierende Belag auf der geätzten Fläche als durchsichtiger Metallspiegel hergestellt wird. Die Ätzmattierung ist viel feiner und glatter als eine durch mechanisches Aufrauhen erzielte, so daß sie das Innenlicht besser durchläßt, aber doch ein blendendes Abspiegeln von Außenlicht, z. B. Scheinwerferlicht eines anderen Fahrzeuges, in ausreichendem Maße verhindert.A completely perfect effect is achieved according to the invention by that the matting by etching and the reflective coating on the etched surface is made as a transparent metal mirror. The etch matting is much finer and smoother than one obtained by mechanical roughening, so that it is the interior light lets through better, but still a dazzling reflection of outside light, z. B. Spotlight another vehicle, prevented to a sufficient extent.
Durch Verwendung eines ätzenden Lackes, der nach dem ätzen auf der Innenfläche der Scheibe verbleibt, kann die reflektierende Wirkung noch weiter gedämpft werden.By using a corrosive varnish, which after etching on the If the inner surface of the pane remains, the reflective effect can be attenuated even further will.
Das Aufbringen des durchsichtigen Spiegelbelages auf die mattierte Fläche in Form einer dünnen Metallschicht, z. B. Silber oder Aluminium, kann auf irgendeine bekannte Weise erfolgen. z. B. durch galvanischen -Niederschlag oder durch Aufdampfen oder feines Aufspritzen.Applying the transparent mirror coating to the matted Surface in the form of a thin metal layer, e.g. B. silver or aluminum, can on done some known way. z. B. by galvanic precipitation or by vapor deposition or fine spraying.
Zum Schutz für den Spiegelbelag kann man auf ihn eine Lackschicht aufbringen. Der hierfür verwendete Lack kann farblos sein, wenn man zwischen der Scheibe und der Lichtquelle ein Farbfilter in der Signalfarbe anordnet. Indessen kann man auch einen die Signalfarbe besitzenden Lack verwenden, so daß ein besonderes Farbfilter sich erübrigt. Infolge der Reflexion bleibt die unmittelbar auf ihn aufgetragene Farblackschicht bei von außen auftreffendem Fremdlicht ohne Einfluß auf die Farbe des reflektierenden Lichtes.A layer of varnish can be applied to the mirror covering to protect it raise. The varnish used for this can be colorless if you choose between the Disc and the light source arranges a color filter in the signal color. In the meantime you can also use a paint that has the signal color, so that a special one Color filter is unnecessary. As a result of the reflection, what remains is that which is directly applied to him Color varnish layer in the case of external light striking from outside without affecting the color of reflective light.
