Definitions
- the invention relates to a light display device for road traffic with a display surface, which is used to display symbols or images self-luminous, screened pixels and one to the front has outstanding shielding device for sunlight.
- a luminous display device such as that described in DE 40 40 567 C1
- projecting cassette-shaped receptacles formed by horizontal and vertical bars are placed in a grid between the pixels become.
- the recordings In order to obtain sufficient shielding from sunlight, the recordings must be sufficiently deep, but the depth thereby is limited that the pixels at a certain observation angle must be visible diagonally from below.
- the vertical Last the lateral viewing angle may be restricted, making it more noticeable the display may be restricted.
- the pixels are also on vertical and horizontal alignment and at a certain distance bound according to the lattice-shaped intent.
- the invention has for its object a lighting display device Provide the type mentioned in the case of improved shielding sunlight better visibility of the display is achieved the arrangement of the pixels is largely freely selectable.
- the pixels individually has assigned shielding elements that are mechanically independent of one another can be positioned on the display surface.
- the shielding device with the separate shielding elements, these can be used accordingly the pixels arranged and with respect to a respective optimal Light shielding taking into account the necessary observation conditions laid out and arranged. For example, on such Any pictograms can be displayed without a Arrangement of the pixels in vertical and horizontal alignment observed must become.
- the individual shielding elements are shaped like a barge, whereby from the free front end of the shielding element to the associated pixel towards the side shielding areas are increasingly pulled down, since the shielding elements are arched sideways over the pixels.
- lateral observation from the front and from below is largely unimpeded guaranteed.
- the pixels are light emitting diodes and that the base into which the LEDs are inserted, are attached to a circuit board.
- a suitable dimensioning results, for example, that the vertical Shielding angle against the horizontal is at most 20 degrees. Also Smaller shielding angles of, for example, 10 ° are more sufficient if warranted Observation conditions achievable.
- a luminous display device 1 with self-luminous pixels in the form of light-emitting diodes 3 arranged on a circuit board 5, above which chute-like light shielding elements protruding towards the front of the observer 2 are arranged for extraneous light, especially sunlight.
- the light shielding elements 2 are molded onto bases 4, which in turn are on the Board 5 are attached and receive the LEDs 3 pluggable.
- the bar-like shielding elements are 2 at a short distance from the outer circumference of the LEDs 3 arranged in the form of an arc from the front, being in the area of the base 4 can touch the light emitting diodes 3 or be minimally spaced are, so that it is only ensured that the LEDs 3 unhindered in the base 4 can be inserted.
- This close arrangement of the Shielding elements 2 with respect to the light emitting diodes 3 and their lateral curvature the light emitting diodes 3 is forward with the smallest possible shielding area and to the side an optimal shielding from flat and side sunlight.
- the length of the light shielding elements 2 is aligned according to a desired vertical limit angle ⁇ for the shield, whereby this is fixed, for example, to a maximum of 20 ° or 10 ° can be, on the other hand a sufficiently large observation angle of is guaranteed below, since that formed by the rasterization of the light emitting diodes 3 Distance between the shielding elements 2 and above each arranged LEDs 3 is sufficiently large.
- the shielding elements 2 When designing the shielding elements 2, the reflection on the one hand To avoid the outside of the LEDs 3, but especially the reflection on the reflector elements 6 present in the light-emitting diodes 3, which change when noticeable of the sunlight is particularly noticeable. With the shielding elements becomes a high contrast for the reliable recognition of the display reached.
- the molding of the light shielding elements 2 on the bases 4 results in simple manufacture and assembly, the individual pixels in the form of the light emitting diodes 3 can be freely positioned on the display surface can, for example, to display any pictogram.
