1. Project Overview ...
The musical fountain with lighting is a comprehensive dynamic landscape integrating water feature shapes, light and shadow effects, background music, and intelligent numerical control. By precisely regulating water pumps, solenoid valves, swing mechanisms and underwater lamps, it synchronizes the changes in water column shape and height with light color and brightness following musical rhythms. This creates a performance effect combining sound, light, water and shadow, and is widely applicable to indoor and outdoor scenarios such as urban squares, parks, commercial complexes and cultural tourism parks. Following the core principles of safety priority, synchronized sound-light-water performance, convenient operation and maintenance, and site adaptation, this design balances the texture of static water features in daytime and dynamic performance effects at night to realize all-day landscape value.
Site survey serves as the fundamental basis for scheme design. It is necessary to verify the pool dimensions, water depth, pool structure and load-bearing capacity to ensure safe equipment installation. Water supply types including tap water and natural lake water shall be distinguished; natural water bodies need supporting filtration and algae removal facilities. Meanwhile, confirm the on-site power supply capacity, distribution box positions and cable routing paths. All underwater equipment shall be treated with waterproof and insulation protection. Taking into account surrounding buildings, wind direction and noise control requirements, measures shall be taken to avoid water splashing and equipment dampness. Targeted winter anti-freezing solutions shall be designed according to local climate conditions.
A single conventional performance track lasts 3–5 minutes, and the full cycle program runs for 10–20 minutes with seamless loop playback. The equipment supports three operation modes that can be switched as required: fully automatic cycle, manual control, and holiday special effects. Centered on the main viewing perspective of the site, the design optimizes water shapes, lighting and equipment layout to guarantee optimal viewing experience.
This scheme adopts multi-level combined water shapes with a mix of static and dynamic effects and distinct layers. One-dimensional straight jet nozzles act as the core primary water shape, which can rise and fall smoothly with musical melodies to fit various music styles. Two-dimensional digital swing nozzles are installed on both sides of the pool, forming curved water curtains through variable-speed swinging to enhance dynamic dancing effects. Universal nozzles are arranged at the center to transform into creative shapes such as waves and flower petals, enriching landscape features. Firework nozzles serve as climax special-effect water shapes with scattered bursting water flow for the highlight segments of music. Sheet water curtains can be used as background water features and upgraded with water screen projection functions. Low fountain nozzles are arranged in the front row to deliver soft and tranquil effects and improve static daytime landscape. The overall layout follows the structure of “central high jets + middle swing jets + low fountain jets”. The height of high jets is controlled within one-third of the short side of the pool to prevent water spray dispersion by strong wind and overflow nuisance.
A closed circulating water supply system is adopted for energy conservation, environmental protection and lower operation & maintenance costs. Supporting equipment includes circulating water pumps, hair collectors, quartz sand filters and automatic dosing devices, which can intercept debris, purify water quality, inhibit bacteria and remove algae to maintain long-term water clarity. Overflow outlets are installed on the pool to stabilize water level, and drain valves are equipped at the pool bottom to meet demands of routine water replacement, equipment maintenance and winter draining for anti-freezing, effectively protecting pipelines, nozzles and water pumps.
DC24V low-voltage RGB full-color LED underwater floodlights are used across the site. They feature reliable waterproof performance, corrosion resistance and aging resistance, suitable for long-term underwater operation. The lamps cover mainstream landscape colors including warm white, deep blue, light green and rose red, supporting multiple light effects such as steady monochrome lighting, gradient color mixing and stroboscopic tracking lights. Lamps are embedded at the pool bottom with precise focusing on water columns and avoiding pump suction inlets. All cable joints are sealed with potting glue for full waterproof insulation to eliminate potential safety hazards.
Lighting is precisely synchronized with musical rhythms with well-defined atmospheric layers. Low-brightness cool-toned gradients are applied in soothing segments to create a peaceful atmosphere; high-brightness multi-color strobing is activated at musical climaxes, paired with bursting water shapes to strengthen visual impact. Light brightness transitions slowly in preludes and endings, coordinated with rising and falling water columns for a gentle opening and smooth closing. Glare avoidance is considered throughout the design; lights focus on water features rather than audiences to ensure viewing comfort.
Outdoor waterproof speakers are placed in dry areas around the pool to deliver uniform sound field and clear sound quality over the whole site. Customizable playlists cover folk music, orchestral music, pop music, epic scores and other styles, supporting switching between daily and holiday playlists. The system preferentially uses pre-programmed linkage mode, where track beats and corresponding equipment actions are pre-imported for high synchronization accuracy and neat performance. It is also compatible with real-time sound pickup mode to support interactive performance with temporary tracks for high flexibility.
The core of fountain operation consists of a dedicated PLC main controller, DMX512 lighting controllers, frequency converters and solenoid valves working in coordination. Frequency converters precisely adjust pump rotating speed to achieve smooth lifting of water columns; solenoid valves rapidly start and stop water flow to realize drumbeat special effects such as water jumping and bursting. All equipment adopts unified timecode synchronous control to guarantee highly coordinated actions of sound, light and water. Dual control modes including on-site touch screen and remote computer are equipped, supporting program editing, scheduled operation, fault self-check and other functions. Built-in water shortage, overload, leakage protection and emergency stop devices ensure comprehensive operational safety.
The project strictly complies with electrical safety standards for water landscapes and adopts separated strong and weak current design. All underwater equipment uses DC24V safe low voltage, while high-voltage power equipment on the ground is independently isolated and protected. Equipotential bonding and earthing are implemented for the entire pool area; all metal equipment, brackets and enclosures are reliably earthed to eliminate risks of electric leakage and static electricity. The circuit adopts graded leakage protection with instantaneous tripping protection stage by stage. Cables are laid inside waterproof sleeves, and underwater joints are double-sealed with potting glue to prevent water seepage and short circuit. Outdoor distribution boxes reach IP65 high protection rating to adapt to complex outdoor conditions such as rain, snow and dust.
The choreography features proper tension and complete rhythm to form a closed audio-visual experience. The performance opens gently with low fountain nozzles matched with soft pale lights for a soothing immersive effect. The main verse mainly uses fluctuating straight jet water columns together with slow light gradients for steady and relaxed rhythm. At the chorus climax, multi-layer water shapes are linked across the whole pool, firework nozzles burst intermittently, and multi-color stroboscopic lights create stunning visual effects. In the ending, water columns gradually drop and lights fade out for a soft close. The whole system cycles 3–6 tracks of diverse styles to effectively prevent aesthetic fatigue.
This scheme features neat equipment layout with simple maintenance and low costs. Daily work only involves regular cleaning of filter equipment, floating debris removal, and inspection of lamp sealing and circuit conditions. Spare consumable parts such as sealing rings and solenoid valves are reserved. In cold regions, accumulated water can be fully drained via pool-bottom drain valves in winter to prevent cracking of pipelines and equipment, requiring no complicated maintenance equipment and ensuring long-term stable operation of the project.
With the rapid development of the cultural tourism night tour industry, water screen light projection shows have become core projects for scenic spots, urban landmarks and commercial complexes to create night tour highlights, attract visitors and boost revenue. Taking a dynamic water screen as the imaging carrier and combining laser projection, colorful lighting, stereo sound effects and 3D digital content, it can deliver a naked-eye immersive light and shadow experience with strong artistic appeal and visual impact. Professional design of water screen light projection shows is the key to stable performance, high-definition images and outstanding atmosphere. This paper systematically elaborates on the design principles, standardized processes, core specifications and pitfalls-avoiding tips of water screen projection shows, providing professional references for the implementation of various night tour light and shadow projects.
A water screen light projection show is a comprehensive performance project integrating hydraulic engineering, light and shadow technology, digital content and intelligent control. Its core working principle: high-pressure water pumps and precision atomizing nozzles form a flat suspended water screen. High-brightness laser projection equipment casts customized images onto the surface of the water screen. Paired with lighting, lasers and synchronized music, it creates a three-dimensional light and shadow performance effect blending virtuality and reality.
Compared with traditional stage light shows and fixed large-screen projection, professionally designed water screen light projection shows boast remarkable advantages and fit a wide range of night tour scenarios:
High-quality water screen light projection shows reject templated design and require customized development according to site conditions and project positioning. The entire standardized design workflow consists of five core stages to fully guarantee stable project delivery and excellent viewing experience.
Preliminary survey and demand positioning lay the foundation for project implementation. Designers need to conduct on-site surveys of water area, water depth and water source conditions. Natural lake water and reclaimed water must be equipped with filtration systems to prevent sediment from clogging nozzles, which would cause uneven water screens and distorted images. Meanwhile, projection distances and equipment installation positions should be precisely measured, and nighttime illumination and wind conditions inspected to avoid interference of strong winds and intense light with imaging effects.
Project core positioning shall also be defined: cultural tourism projects focus on Chinese-style landscapes and regional culture; commercial scenarios feature technological, trendy and cool styles; urban landmarks emphasize the display of cultural heritage. Performance duration, playback frequency and core themes are determined to set the tone for subsequent design.
Water screen flatness directly determines projection clarity and constitutes a core hardware component. The mainstream types in the industry include fan-shaped water screens, linear water screens and fog screens. Among them, fan-shaped water screens deliver stable forming and wide coverage, fitting over 90% of outdoor projects with the best cost performance.
Design requires precise adjustment of pump power to ensure the water screen is even, continuous, free of breaks and density differences, and to avoid fragmented images caused by excessive water flow. Supporting water circulation, filtration and voltage stabilization systems are deployed to achieve water-saving operation and cut maintenance costs. In addition, the water screen width is customized according to site dimensions to accurately match the parameters of projection equipment and eliminate problems such as dim and blurry images caused by an oversized screen.
Scientific matching of light and shadow equipment is critical to improving performance texture, mainly covering four systems: projection, lighting, laser and intelligent central control.
For projection equipment, ALPD laser light source high-lumen projectors are preferred for their anti-interference capability, long service life and high color reproduction. Conventional outdoor scenarios require no less than 20,000 lumens for water screens within 30 meters; sites with strong urban light and extra-wide open spaces need ≥30,000 lumens to prevent washed-out images and missing details. Projection distance is strictly calculated per standard formulas with safety margins reserved to avoid image distortion and blurriness.
The lighting system adopts RGB full-color lamps. Gradient, follow-spot and flickering effects are designed in line with music and image rhythms. The collocation of warm and cold tones creates layered atmosphere. Colored laser beams are supplemented to form aerial light and shadow lines, constructing a multi-dimensional three-dimensional light and shadow space. All equipment connects to the intelligent central control to realize millisecond-level linkage among water screen, projection, lighting and music. Timed playback and remote control are supported for convenient and efficient operation.
Hardware lays the foundation while content endows performances with soul. To avoid homogenization, water screen projection shows require customized thematic scripts. The industry standard performance duration is 8–15 minutes, matching tourists’ sightseeing pace and enabling loop playback without redundancy. The minimum image resolution is 1080P, and 4K ultra-high definition production is adopted for high-end projects to guarantee sharp image details and refined viewing experience.
There are three mainstream content styles: Chinese-style cultural tourism integrates ink-wash landscapes and folk historical elements to build a poetic immersive realm; the tech style uses 3D modeling, particle special effects and dynamic geometric graphics to create a futuristic vibe; the commercial trendy style combines brand IP and trendy animations to meet commercial drainage demands. All images must be precisely synchronized with audio and lighting rhythms, combining motion and stillness and progressing layer by layer to form a complete performance narrative.
After equipment installation, refined debugging and calibration are carried out: adjusting projection focal length and angle to solve ghosting and distortion; fine-tuning pump pressure to improve water screen flatness; polishing the linkage rhythm of lighting, lasers and music. Debugging is also performed for different wind and nighttime light conditions to ensure stable performance under various weather conditions. Final acceptance is completed against industry standards and client requirements, with operation and maintenance schemes delivered.
Most problems of water screen projection projects, such as blurry images, broken water screens, out-of-sync light and shadow and cheap visual texture, stem from substandard design parameters and inadequate detail control.
