Jensens Bofhus is an established Danish casual-dining brand known for classic steaks, artisanal burgers, and family-friendly hospitality, operating prime restaurant sites across major Danish cities including Copenhagen, Aarhus, and Odense. Seasonal campaigns form a central part of their business model. During traditional Danish cultural holidays such as Great Prayer Day (Store Bededag), the chain introduces seasonal culinary specials like its signature "Bededagsburger" for 149 DKK alongside limited-time promotional offers ("TILBUD!").
To maximize patio seating utilization and capture walk-in customers along competitive pedestrian high streets, Jensens Bofhus required an eye-level digital signage display capable of presenting vivid food visuals directly to sidewalk foot traffic.
Deploying commercial digital displays along historic European city promenades presents specific operational constraints:
Strict Municipal Pavement and Cabling Bans: Municipal preservation regulations throughout Danish urban centers strictly forbid ground trenching, bolting fixtures into stone pavements, or trailing electrical cords across pedestrian walkways. Permanent hardwired outdoor totems were unfeasible.
Limitations of Traditional Chalkboards: Conventional wooden sandwich boards and printed posters fail to showcase dynamic video content of fresh, appetizing food. Updating print graphics for seasonal specials or daypart shifts incurred high recurring production costs and operational delays.
Direct Solar Glare and Screen Blackening: High ambient daylight causes severe glare on standard screens. Unshaded solar radiation also heats conventional LCD panels beyond their clearing point (around 75C), resulting in permanent dark patches across the active display area.
Daily Portability and Nighttime Security: The display needed to be moved to the sidewalk line during business hours each morning and rolled indoors at closing by regular floor staff to prevent overnight theft or vandalism.
To eliminate cabling restrictions while ensuring outdoor durability, Jensens Bofhus deployed the Lumi Link 43-Inch Mobile High-Brightness Battery-Powered Outdoor Digital A-Board (LL-PPD-43) directly on its outdoor dining perimeter.
Full-Shift Battery Operation: Integrated with a high-capacity rechargeable lithium battery pack, the display operates continuously throughout daily lunch and dinner trade without external power cables. A dedicated LED battery meter allows staff to check remaining power levels instantly.
Ergonomic Folding Chassis: Built with an A-frame folding structure, balanced center of gravity, heavy-duty rear wheels, and a built-in pull handle. A single floor-staff member can roll the unit out to the terrace, open the rear support stand, and wheel it back inside at closing time within seconds.
Sunlight-Readable Direct Backlight: The 43-inch commercial IPS panel outputs 1,800 nits of brightness, preserving rich color saturation, deep contrast, and sharp food graphics under direct midday daylight.
Intelligent Light Sensor: An integrated ambient optical sensor continuously tracks daylight changes, scaling backlight intensity automatically between full sun, overcast skies, and dusk to maintain optimal readability while conserving battery runtime.
-50C to +110C Wide-Temperature Substrate: The commercial panel utilizes specialized wide-temperature liquid crystal technology that withstands solar radiation up to 110C without screen blackening, while enabling reliable cold starts during freezing Nordic winters.
6mm Anti-Reflective Optical Safety Glass: The display face is protected by 6mm AR laminated tempered glass, reducing external reflections so passing pedestrians see crisp digital promotions rather than street reflections. The tempered glass construction shields the panel against accidental impact and scratch damage.
All-Weather Galvanized Construction: The cabinet is manufactured from heavy-duty galvanized steel finished with outdoor anti-corrosion metallic powder coating. Certified to IP65 weatherproofing, it seals internal electrical circuits completely against dust ingress and water jets from any direction.
Internal Air-Cooled Heat Dissipation: Internal thermal management combines military-grade aluminum heat sinks with low-noise air cooling, expelling heat without drawing outdoor moisture or dirt into the sealed electronics bay.
The display integrates dual-channel stereo speakers (8 ohm, 2x10W) and an onboard multimedia processor supporting more than 30 video and audio formats, including H.264, MP4, MOV, MKV, and AVI.
Restaurant managers can update holiday specials, promotional pricing ("TILBUD!"), or afternoon drink deals on the fly via USB plug-and-play or over local Wi-Fi.
Direct Lift in Walk-In Conversions:
The eye-level 43-inch digital promotion for the "Bededagsburger" (149 DKK) caught the attention of pedestrians along the promenade, driving spontaneous walk-in visits and lifting sales of featured holiday specials.
Zero Civil Engineering and Permitting Costs:
By removing the requirement for trenching, drilling, and street power permits, the restaurant avoided costly site preparation and launched digital marketing operations without delay.
Dayparting Agility:
Staff can switch the display between lunch offers, afternoon coffee specials, and evening steak dinners instantly, removing ongoing chalkboard preparation and printed poster expenses.
Modernized Brand Image:
The slim, contemporary profile of the Lumi Link digital A-board integrated into the historic urban streetscape, giving the venue an attractive commercial presence compared to static chalkboards.
