South Korea-BTS's "Boy with Luv" performance-Dynamic Bars

• A company provides 150 sets of Dynamic LED bar, supporting technical solutions (including multi-equipment collaborative control, cultural visual customization) and on-site technical support for the Korea-BTS'Ss "Boy with Luv" TV Show.

• During the preparation and official broadcast of theSouth Korea-BTS's Boy with Luv TV show performance (including 3 days of on-site construction, 2 days of joint rehearsal, and 1 day of official live broadcast).

This project aims to explore the innovative application of 150 dynamic LED bars, integrated with a traditional stage lighting system, to comprehensively showcase a boy band's youthful vitality and their precise interaction with music. Tailored for the unique demands of a live TV broadcast, the goal is to create a visually dynamic and immersive stage. Specifically, 150 individually programmable LED bars will be strategically deployed across the stage floor, backdrops, and custom props. They will function not as static decorations but as "dancing lights," becoming an integral component of the performance. Through pre-programming, these bars can execute a variety of dynamic effects, including chases, waves, color gradients, and strobes. Their core value lies in their perfect synchronization with the music. For instance, on a drum beat, the bars can trigger intense shifts in brightness and color. When the members execute a signature synchronized dance move, the lights can create radiating or focused effects, visualizing the power and rhythm of the choreography. This tight integration translates the intangible energy of the music into tangible visual impact, dramatically enhancing the performance's immediacy and emotional resonance. For the live broadcast, we will place special emphasis on coordinating the lighting effects with the cinematography. Through meticulous lighting design, we will ensure that from wide shots to close-ups, the lighting effectively outlines the members' silhouettes and uses dynamic effects to guide the audience's focus, highlighting the center performer and key formation changes. This approach aims to create an electrifying audio-visual experience for viewers on screen, rivaling the impact of a live concert.

• To Achieve Technological Innovation & Visual Upgrade: To break through the static lighting paradigm of traditional TV shows by successfully integrating this advanced dynamic LED system. Its flexibility will inject an unprecedented sense of technology and dynamic visual expression into a compact stage, setting a new benchmark for similar productions. • To Deepen the Performance's Artistic Expression: To utilize dynamic lighting as a key narrative and rhythmic tool, achieving frame-perfect synchronization with the group's energetic choreography and complex formation changes. The lighting will function not just as a backdrop, but as a "second dance troupe," externalizing the music's emotion and amplifying the vitality and impact of every dance move. This creates a cohesive, highly captivating, and memorable performance. • To Generate Viral Marketing Impact: To create shareable "highlight moments" (e.g., an iconic "light wave" or "human-light interaction" sequence) through high-impact, interactive lighting. These moments are designed to generate buzz and go viral on social media platforms (like TikTok, Weibo, etc.), thereby boosting the boy band's public profile and influence. Ultimately, this will feed back into the program itself, driving a sustained increase in ratings for the current and subsequent episodes.

150 Dynamic bars needed to synchronize with three core elements in real time:
BTS's group formations (e.g., when members form a line, the bar array follows to create a "light frame"), the song's upbeat rhythm (e.g., 128BPM tempo requiring 0.48-second interval color changes), and AR visual effects (e.g., matching the bar's blue tone with on-screen "butterfly" AR graphics).
Any delay over 0.3 seconds would disrupt the stage's coherence.

International tour stops had varying venue conditions:
① Voltage differences (110V in North America vs. 220V in Asia);
② Signal frequency conflicts (e.g., European venues using 5GHz Wi-Fi that might interfere with Dynamic bar controls);
③ Language barriers (needing to collaborate with local stage teams in Korean, English, and Spanish), increasing the risk of deployment errors.

BTS's stage requires "real-time fan response"—the team hoped Dynamic bars would brighten automatically when fans cheered above 85 decibels (a common volume for ARMY chants).
Traditional equipment lacked sound-sensing and real-time adjustment functions, making it difficult to achieve this "stage-fan feedback loop."

Each tour stop had only 24 hours of local venue access (due to international logistics and venue scheduling).
150 Dynamic bars needed to be unboxed, installed, debugged, and integrated with local systems within this window—traditional manual single-unit debugging would take 36+ hours, failing to meet the timeline.

◎ Develop a "distributed synchronous control system": Equip each Dynamic bar with a low-latency wireless module (latency < 0.2 seconds) and connect 150 units to a central control platform.
The system uses "formation position mapping"—pre-input BTS's 12 core choreography formations, so the bars automatically adjust their light positions and colors when the members move to a preset formation.

◎ Preset "song rhythm effect templates": For Boy with Luv's verse (warm yellow gradient), chorus (pastel blue jumps), and bridge (pink-white fades), pre-program 3 sets of effect templates.
The on-site technician can trigger templates with one click, avoiding real-time adjustment delays.

◎ Design a "global adaptive Dynamic bar": Equip the equipment with a dual-voltage power supply (100-240V) and a multi-frequency wireless chip (supporting 2.4GHz/5GHz dual bands), enabling automatic adaptation to local voltage and signal environments.

◎ Establish a "cross-language technical support system": Prepare multi-language (Korean, English, Spanish, Japanese) operation manuals and deploy a 3-person bilingual technical team (fluent in Korean and English) to collaborate with BTS's core stage team and local venue staff.

◎ Add a "sound-sensing smart module" to each Dynamic bar: The module detects on-site decibel levels in real time—when fan cheers exceed 85dB, the bar's brightness increases by 40% and switches to the song's signature pastel pink tone, creating a "fan-cheer light response" effect.

◎ Link with BTS's official ARMY stick (fan light stick): Develop a Bluetooth connection function between Dynamic bars and ARMY stick —when 10,000+ ARMY stick are activated simultaneously, the overhead Dynamic bar cluster forms the BTS logo, enhancing fan immersion.

◎ Adopt "modular pre-assembly": In the factory, group 150 Dynamic bars into 15 modular units (10 bars per unit) with pre-wired power and control lines. On-site, only module installation and central platform connection are needed, reducing deployment time by 65%.

◎ Develop a "one-click batch debugging APP": Technicians can use a tablet to connect to all modules, conducting batch tests (signal strength, color consistency, sound-sensing sensitivity) in 1.5 hours, compared to 8 hours for manual debugging.

▪ Stage Effect Outcome: Boy with Luv performances with Dynamic bars became a "viral stage highlight"—related topics (e.g., "BTS Dynamic Bar Stage," "ARMY Cheer Light Response") accumulated 500M+ views on global platforms (Twitter, TikTok, Weibo).
▪ Media reviews noted: "The 150 Dynamic bars turn the stage into a 'living light canvas,' perfectly matching the fresh vibe of Boy with Luv."
▪ On-site surveys showed 96% of ARMY fans rated the "fan-cheer light interaction" as their favorite stage element.

▪ Product Verification Outcome: Across 8 international tour stops, 150 Dynamic bars had a total fault rate of 0.6% (only 1 bar with signal loss, quickly replaced by a spare).
▪ The average synchronization delay was 0.15 seconds, and the fan interaction trigger accuracy reached 98%.
▪ The equipment adapted to all venue voltages and signal environments without errors.

▪ Brand Exposure Outcome: The project was reported by 30+ international industry media (e.g., Billboard Live, Stage Directions).
▪ Within 2 months after the tour, the company received cooperation inquiries from 12 global entertainment companies (e.g., U.S. concert promoters, K-pop agency HYBE's other artist teams) and signed a 2-year supply agreement with a European music festival organizer.

The project established the company's "global flexible stage equipment leader" image—the BTS case became the core sample for overseas promotion, increasing the product's international quotation premium by 25% and entering the global K-pop and Western concert equipment supply chain.

It promoted the upgrade of global live entertainment equipment—before the project, only 20% of international tours used batch-sync light bars; after the project, 50% of top artist tours (e.g., Taylor Swift, BLACKPINK) began adopting similar fan-interactive dynamic light equipment. The company's "global adaptive hardware standard" was referenced by 4 international equipment manufacturers.

Based on global feedback, the company launched an upgraded Dynamic bar (supporting multi-language APP, enhanced Bluetooth linkage) and expanded applications to international events (e.g., FIFA fan zones, global brand launches), increasing global market share by 40%.
