Definitions
- the invention relates to objects whose shape and surface are designed in a certain way to achieve an aesthetic effect.
- the invention relates in particular to a decorated object which has a transparent body of a certain shape, on the surface of which a layer system is provided for producing interference effects.
- optical components are known and common. Examples are high-performance mirrors, filters and beam splitters. An overview is contained in
- Usual coloring is done by adding substances that absorb a certain wavelength range. The object then appears in the color of the unabsorbed wavelengths. This mechanism mainly occurs when the light is transmitted, hardly in reflection. Absorbing coloring is characterized in that part of the light is destroyed. An object colored in this way appears dark. The purer and deeper the color, the more light has to be absorbed and the darker the object. This effect is particularly noticeable when the color is to be used as a decorative element to achieve an aesthetic effect.
- the absorption is a property of the substances used, so that the available colors are limited by the number of suitable substances. Since the dye is absorbent, the mixture of different substances usually results in a dirty mixed color.
- absorption-free interference layer systems have so far not been used for decoration. It can be assumed that The following fact is decisive for the non-use: The color effect of absorption-free interference layer systems shows a pronounced dependence on the lighting conditions. In particular, it is harmful for an application that the color effects almost disappear under normal, reasonably uniform, lighting.
- color depth K is used for explanation.
- Triple layers can be reached (Tab. 1). It does not prepare
- Fig. 1 shows a typical lighting.
- a transparent object G which has an interference layer S, is located above a base U (e.g. a table) and is
- the intensity is composed of the intensity A incident from the left, multiplied by the passage T and the
- Tab. 2 shows the color depth K as a function of V and R for the case concerned in FIG. 1.
- the uncoated back of the item is neglected.
- the maximum reflection 60%, 81%, 93%, 96% corresponds to 3, 5, 7, and 9-fold layers (Tab. 1).
- Tab. 2 also shows the values of K for non-uniform illumination.
- the average of K at different values V is a measure of the decorative effect under normal lighting conditions ⁇ . It is interesting that the average of K cannot be increased significantly by using a large number of layers.
- Gain in color depth is very small. It can not be prevented, even with any number of layers, that
- V 1
- D3 is based on the observation that even shallow depths of color are sufficient for decoration if it is ensured that different colors are viewed simultaneously.
- V 1 can hardly be mitigated by the regulation according to D3.
- the object of the invention is to provide an object using a layer system and a transparent body
- the layer system comprises a sequence of at least three interference layers of changing refractive index
- the transparent body is designed in such a way that, in the normal position of use of the body, at least one coated surface area can be viewed through a second coated surface area.
- the regulation according to the invention sets two independent
- One mechanism creates colored reflections
- the second mechanism increases the depth of color and also prevents the color from completely disappearing under normal lighting conditions.
- Mechanism 1 enhancing the depth of color, preventing the
- Fig. 2 shows the previously considered case that an object G is on a support U and obliquely from above
- the object has two coated surface areas according to the invention.
- FIG 5 shows an object G, for example a glass body with a curved surface (champagne glass)
- the invention enables
- Reeflex act from a light source of high luminance, or the light of an angular range is detected and focused on the eye of the observer.
- the bundling is indicated in FIG. 5 by three beam paths.
- the reflex also occurs at other angles of incidence and viewing.
- the angle of incidence and the viewing angle do not have to be the same size.
- the height of the reflex is then shifted on the glass. In other words, an entire reflection line often results under normal lighting.
- the 3rd order reflex appears at a defined distance from the 2nd order reflex. If the
- the embodiment according to the invention is very well suited for decorating transparent objects.
- the resulting reflexes create the impression of "strongly sparkling” to an unprecedented degree.
