Definitions
- the invention relates to an object for transmitting light, for example a lamp bulb or a lamp cover.
- turn signals as well as the taillights of automobiles subject to strict official regulations. That's what it demands Federal Motor Transport Authority that the light emitted by turn signal lamps of yellow Color is. The requirements are very strict and include a tight one Definition of the color coordinates.
- the single turn signal lamp sits in a housing, the one Has cover.
- the cover is made of glass or plastic. It is accordingly to achieve the color required by the authorities colored accordingly. However, the coloring is from the point of view of the Designers undesirable as this is an aesthetic conflict with the rest Color of the car can occur.
- lamps are also used to solve the problem Glass body colored or painted accordingly yellow. is.
- the cover the housing in which the lamp body is located is colorless. This configuration was also unsatisfactory from an aesthetic point of view.
- the Designer experts speak of a fried egg effect, the yellow one Lamp body under the light-scattering colorless cover.
- a dielectric coating has also already been presented.
- the lamp body is provided with a dielectric layer.
- This Incandescent lamp emits the required yellow light when switched on and produces a bluish reflection of the Ambient light.
- the invention is based in general on the object of an object to create the light one on the first side of the light specific color emitted on the second side.
- the inventors are an incredibly simple but very effective way went. They coat the body with a varnish designed in this way is that it only hits light in a certain color (Transmission color) lets through (transmitted). On this paint is a dielectric coating applied in such a way that that on the second Side reflected ambient light appears bluish.
- the order of Combination of lacquer and the electrical coating is for the optical Effect decisive.
- the Incandescent lamp is covered with a varnish that has such properties that the prescribed yellow transmission color T of the emitted light sets.
- This incandescent lamp is also with a dielectric layer coated, which is selected such that when not switched on Incandescent lamp sets a reflection color R of the ambient light that is preferably bluish.
- the wavelength ranges of T and R are chosen such that mutual interference does not occur. It finds one Separation of function and visual appearance (design) instead.
- the invention solves the stated problem in a perfect manner.
- the official requirements for car indicators and taillights fulfilled by the yellow or red light of the desired properties is transmitted.
- the light bulbs have in switched off, the bluish reflection desired by the designer of ambient light.
- the cover of the turn signal or taillight housing is executed colorless in this case. But it is also possible to use the lamp colorless and the described layer combination on the Apply cover. It is also possible to use a yellow lacquered lamp to use and the cover with the dielectric portion of the Coating.
- Curve A is the curve "reflection dielectric coating”
- curve B is the curve "transmission varnish”.
