In a quiet industrial zone of Seoul, CEO Kim sipped his coffee under a worn-out signboard as he stared out the window. His company, "Life ****," was a mid-sized household goods and beauty device manufacturer. While the brand was well-known in Korea, Kim had bigger dreams—he wanted to introduce its products directly to European and Southeast Asian consumers.
Distributors? Too old-fashioned. He boldly chose vending machines as his solution. Airports, hotel lobbies, and convenience stores would become the stage for his smart vending units.
In the spring of 2024, Kim gathered his team and shared his plan.
He announced, "We will present our vending machine at an international trade show. It will support card and QR code payments—simple and direct."
The team was fired up. This vending machine wasn't just a sales box—it needed to become a "digital showcase" at night, grabbing attention with dazzling LED signage. However, the challenge emerged quickly: outdoor units would face harsh weather, especially rain. Regular LED panels lacked waterproofing, and moisture seeping through the corners was a notorious cause of electrical failure.
Late into the night, Kim combed through resources. Then, a name caught his eye: Lumispace. With over 20 years of experience manufacturing subway and solar-powered outdoor signage, they have unmatched waterproof lighting and structural engineering expertise.
Lumispace's office was modern and pristine. Sitting across from the Lumispace CEO, Kim laid out his vision:
"The display needs to be at least IP65-rated, with brightness over 1000 nits. The size should be 1200x300mm to fit atop the vending machine."
CEO Lee Soo-jin nodded.
"I suggest a custom LED panel of the indoor-outdoor hybrid type. And don't worry about rain—it won't be a problem."
Lumispace's engineering team sprang into action. They designed a drainage structure that redirected rain down the frame's outer edges. A subtle water-shedding angle was built into the panel's border, while dual-layer silicone sealing inside the frame blocked all infiltration paths.
Watching the meticulous process, Kim couldn't hide his admiration:
"This isn't just a signboard—it's a piece of art."
Innovative technology was also embedded. High-brightness LEDs lit up at night, while an auto-dimming feature saved energy during the day. Integrated heat-dissipation channels ensured safe operation even during prolonged use.
Most impressively, the transparent diffusion cover softly spreads the light, creating a stunning effect from any viewing angle.
Kim smiled as he watched the test video.
"This isn't just an ad panel. It's a magnet—it pulls people in."
The prototype underwent grueling tests at an outdoor site on the outskirts of Seoul. It endured 12 hours of continuous rain simulation and wide temperature fluctuations. The results were flawless: no internal condensation and no brightness drop.
"We're off to Frankfurt," declared team member Dohyun, exchanging high-fives with the Lumispace crew.
At the 2024 Frankfurt Consumer Goods Fair in Germany, the vending machine with Lumispace's LED panel stood out. Its vivid lighting and crystal-clear display made buyers stop in their tracks. One visitor even skipped the vending machine and pointed directly at the signage.
"Where is this display from?"
Kim confidently replied,
"It's from Korea—Lumispace."
After the exhibition, the vending machines were installed in retail locations across Malaysia, Singapore, and the Czech Republic. Most notably, nighttime sales rose by 238% compared to the previous month—clear proof of the signage's impact. Lumispace and the vending company sealed a global partnership.
With a perfect trifecta of LED, signage, and waterproof design, Lumispace emerged as a serious player on the international stage.
But they didn't stop there.
They began developing next-generation smart panels featuring IoT sensors and interactive touch capabilities. When a customer approached, the lighting would adapt automatically, and personalized advertisements would appear. Over a glass of wine, Kim smiled and told CEO Lee:
"Our vending machines will change the world."
She smiled back and said,
"And our light will lead the way."
