Illuminable information unit

A technology for illuminating information and components, applied in the directions of light guides, optical components, light guides, etc. of the lighting system, which can solve the problems of increased manufacturing costs, the concave symbols or letters do not have the desired contrast, and cannot be perceived clearly enough to achieve a compact structure. , the effect of good recognizability

Problems solved by technology

Since several components are required, strict adherence to specified tolerances must be observed during manufacture and development, which leads to a further increase in manufacturing costs
Yet another disadvantage of using a combination of diffusing lenses and a diffusing plate arranged downstream lies in the fact that, under non-illuminated conditions during the day, the debossed symbols or letters do not have the desired contrast to the paint, so that neither of them can suffice Clearly perceived, or although no lighting is implemented, relying on painted tints that undesirably look like they are switched on, or undesirably have the appearance of being switched off

Embodiment Construction

[0028] First, in FIG. 4, the display unit schematically corresponds to the state of the art. The display unit includes a photodiode 1, a photodiode housing 2, a scattering lens 3, and a display housing 4. The display shell 4 is coated with an opaque paint layer 5. The opaque lacquer layer 5 has depressions 6, in each case showing where the outer casing 7 of the casing 4 is released. The area of ​​the outer side 7 of the housing released by the recess 6 forms a visible symbol in the plan view 8 with respect to the opaque paint layer 5. It can be further deduced from FIG. 4 that the light illumination 10 emitted by the photodiode 1 is basically bundled, and therefore approximately incident on the scattering lens 3 adhered to the photodiode housing 2. The light illumination 11 slightly expanded by the scattering lens 3 has a slightly larger divergence angle than the emitted light illumination 10 and is incident on the display housing 4. Slightly expanded light irradiation is emitted ...

Abstract

The aim of said invention is to produce an information unit for technical devices and machines, in particular for vehicle accessories which is readable day and night independently of the angle of view. For this purpose, the visible display elements (6) of said information unit comprises at least one light-diffusing plastic element (4) in which transparent and/or coloured transparent diffusers are inserted into a transparent and/or coloured transparent plastic compound (4).

Description

Technical field [0001] The invention relates to an illuminable information unit of a technical device or machine, especially a vehicle accessory. Background technique [0002] Such information units are well known in many embodiments, for example in the automotive field. Here, it is a problem to indicate to the driver an increasing amount of data about the operating state of the vehicle or the installation on the vehicle through an optical signal provider or the like. [0003] For example, data on the on state of the rear window heating, information on whether the anti-lock brake system, seat heating or ESP is activated, on various external light-emitting units such as driving lights and / or low beam lights or fog lights or rear fog lights The information of the switching status is displayed in the form of a display. [0004] For safety reasons, vehicle manufacturers require that the information expressed in this way be well identifiable during the day and night. In particular, in...
