Description

The invention relates to a display device with a frame, with associated with this lighting devices and control devices.

A generic display device is known from EP 1 293 955 A2. Such devices may be combined in combination into large display panels and as such may be used for display at major events such as sporting events and music events.

The known device is complex and rigid in construction, in particular, the local lighting devices can be used only in the frame-like devices themselves, are difficult to separate from these and can not be used otherwise.

The invention is based on the object, a known display device of the type mentioned above to further develop that both the individual lighting devices and the electronics can be used in a more flexible manner.

According to the invention, the object is achieved with a lighting device of the type mentioned above, which is characterized in that the lighting devices and / or the control devices are removable in a simple manner from the frame and connectable to this. As a result, the holding security is increased.

In a constructive embodiment, the invention provides that the lighting devices are held by elastic clamping devices on the frame, in particular, the clamping devices are retaining clips. In a further preferred embodiment of the invention can be provided that the clamping device are provided at least in their attacking on the lighting devices area with a plastic coating or a rubber coating.

To increase the flexibility of the use of the control electronics, the invention provides in a further preferred embodiment, that the control electronics is arranged in a frame part usable electronics housing, in particular connectable to the lighting devices and the electronics housing plug contacts are present and that the frame in the region of the plug contacts of the electronics housing used breakthroughs. By easily releasably attached to the frame rod-shaped lighting devices (glow sticks) they can be easily replaced and replaced in the event of damage. In addition, they can also be used elsewhere, detached from the frame. The same applies to the inventively arranged in a separate electronics housing control electronics, either in the frame, in particular a frame part the same is used, or separately connected by this with lighting devices and can be used for controlling dissolved by the frame lighting devices. Lighting devices can be arranged, for example, band-shaped. In particular, when lighting devices and control electronics and electronics housing are detached from the frame, connection cables can be used to connect the electronics housing and the individual lighting devices.

A sturdy rectangular or square frame allows multiple frames to be connected together to create larger display elements.

Control of the control electronics via the standardized DMX512 protocol facilitates integration into existing decoration systems.

In the combination of multiple frames to a large display element, it is advantageous that the light rods are mounted in front of the frame in the viewing direction. This gives the visual impression that the combined individual scoreboards form a large contiguous scoreboard.

Likewise, it is advantageous in the construction of larger interconnected systems that the connections for power supply and control are looped through. This minimizes the amount of cabling, since short cables can be used to connect frames to frames. By combining several light pixels and simultaneous and the same control of the same, the technical complexity in the control electronics is significantly reduced, which in turn means that the display elements are inexpensive to manufacture. The light pixels are preferably in Squares summarized, since thereby the control can be independent of the number of combined light pixels.
