Ventaluz.
Your presence, right on the screen: brand, offers and promotions in your own design — as natural as on your website, with no print shop and no waiting. Paired with service that picks up the phone.
Change the dish of the day? Three seconds — and every screen follows.
The menu, digital — discreetly integrated into the interior.
Visible, even when the shop is closed.
How it works
Your shop window, in your hands.
Use your own screen or buy one, connect the controller, deliver your content — and if you like, we take over design and operation entirely. A price you can work out in your head: one base fee per store, plus 20 € per controller.
Hardware, set up once.
You use your own screen or buy one on our recommendation. We deliver the Ventaluz controller preconfigured — one piece of content per controller, on several screens at once if you wish.
How the process works →Your own content, live in an instant.
Offers, opening hours, photos, promotions: you supply the material, we build your slideshow from it. Changes we roll out remotely — no poster printing, no waiting.
Plans & pricing →Operation without the effort.
Maintenance, updates and support come from us — with a named contact. On request we take over design and content entirely.
Get in touch →01 · Modules & apps
One screen, everything your business has to show.
Assemble your display from ready-made modules — menu, weather, opening hours, key figures, wayfinding and more. A selection from the module catalogue — which modules your location gets, we settle during setup.

Our stance
No glaring ad sign. A better business.
A display can be a neon hell — flashing, loud, slapped on. Or a calm, well-thought-out tool that suits the shop and genuinely helps customers. We prefer the latter: discreetly integrated, in the interest of your business — instead of simply sticking an advertising sign on the wall.
In practice
This is how it looks in the window.
Two displays in the shop window of an optician in Kaarst, in operation since July 2026: offer panels in landscape, services and opening hours in portrait. Designed in the customer's look, updates we roll out remotely — the controller sits invisibly behind the display.

Fields of use
Everywhere people walk by.
Four sectors, four sets of requirements. What looks different in fashion than in hospitality, what real estate does differently from chains — and what they all have in common: a shop window that can sell.
Lookbook in the shop window.
New collection in motion. Season change without poster printing. Sale phases at the click of a button.
The menu in the window.
Dish of the day, digital. Happy hour on a schedule. Cafés show breakfast in the morning and cocktails in the evening — automatically.
Listings that stay current.
Sold properties disappear, new ones appear — without anyone having to swap posters. Visible 24/7, on Sundays too.
Pharmacies, opticians, banks & more.
Hundreds of locations with an identical presence. Central control, local adjustment — when the branch in Bremen needs something of its own.
03 · What it can look like
Five environments, one system.
Illustrations of how Ventaluz works in typical environments: shop window, bar, supermarket, kiosk and foyer, by day and by night, with sample content from the modules. Two views show the guest with a phone in hand: at the bar counter and at the reception in the foyer. Not photos, but examples that show proportions and lighting.
All views are illustrations, not photos; the content on the screens is sample content. What it looks like in your shop, we settle on site, with your measurements and your content.
Get in touch ↗Who is behind it
Optical practice meets web studio.
Ventaluz is a cooperation between Haufschildt Optik GmbH and the Lightsignalmedia Group. One side has known everyday life in the shop window for decades, the other builds the digital infrastructure behind it.
We build what we would run ourselves: robust, honest, long-lasting. No venture-capital story. Instead: close collaboration with our customers, named contacts, service that picks up the phone.
A cooperation brand of two complementary houses — one from optical and shop-window practice, one from digital tool development. Together we build Ventaluz: digital shop windows for local businesses.
