Playing in water during summer is truly the best! Recently, a youth palace's water world has gone viral online, becoming a popular spot for water activities, attracting many citizens to come and enjoy the water. Visitors can not only dive down from Hurricane Bay and the high-speed time tunnel slide to experience speed and excitement; they can also feel the refreshing sensation of 1.5-meter-high waves hitting them in the wave pool; or they can go to the magical river ride to enjoy a leisurely and pleasant time on the water, experiencing the thrill of water play and drifting.。

　　In this treasure-like summer retreat that combines interactivity,观赏性,趣味性, and entertainment, the 'Mystical Drift' tour around the scenic area is created by dozens of high-quality NEC laser projectors equipped with customized smart projection cabinets. The 'Underwater World' is beautifully dreamlike, the 'Space Walk' is technologically advanced, and the 'Primal Forest' is thrilling. These three cave drift experiences each have their unique features. Visitors lie on floating rings, leisurely enjoying the changing scenery, taking in beauty and coolness at every step.

   Eight NEC PA703UL+ projectors, paired with eight NH10K projectors, create a dreamlike experience of drifting through a cave in an ocean world.

　　Following the drifting route, visitors first arrive at the enchanting and dreamlike Cave No. 1, which is modeled after a shallow sea world. Eight NEC liquid crystal laser projection machines PA703UL+ (7000 lumens, WUXGA resolution) are installed on one side of the cave wall, along with eight customized IPX5 waterproof projection boxes NH10K. These projectors create a vivid and colorful ocean world using immersive semi-shadow projection. Moving forward, visitors then enter the technologically advanced Cave No. 2 — Cosmic Walk. Using lighting equipment, the cave walls are projected with starry sky and universe-themed backgrounds, combined with full-color lighting to create a stunning cosmic starry sky scene. Finally, visitors reach Cave No. 3, which is modeled after a primeval forest. Twelve NEC PA703UL+ projectors are used along with twelve projection boxes NH10K, embedded into the cave walls on both sides. Immersive panoramic projection is employed to create a comprehensive visual experience space that integrates river valley exploration, rainforest scenery, and jungle adventure, providing visitors with thrilling sensory experiences. 

12 units of NEC PA703UL+ equipped with 12 units of NH10K create an adventurous experience of drifting through a primitive forest cave.

　　It is well known that the installation environment inside caves is complex and harsh. Projectors not only face high humidity, large temperature differences, and poor ventilation, but also extremely complex installation angles. Therefore, projecting a stunning and stable light and shadow show inside a cave poses a severe challenge for both the projectors and their enclosures. NEC PA703UL+ excels with its high brightness, high resolution, and wide REC.2020 color gamut, making marine animals lifelike and vivid, and bringing plants, trees, and wild animals in the primeval forest back to life, allowing visitors to fully immerse themselves in a dazzling light and shadow feast. Additionally, PA703UL+ comes with built-in edge blending, ensuring smooth and natural transitions in the blending area and maintaining high color consistency across multiple projectors. Notably, to address the high humidity inside caves, the professional smart projector enclosure NH10K, custom-made for NEC PA703UL+, uses optical glass with a transmittance of over 96%, and features specially designed demisting structures on both sides of the glass to effectively prevent fogging, further ensuring the high-definition and vivid display effect of the projector inside the cave.

The NH10K customized professional smart projector enclosure ensures high-quality display for PA703UL.

　　For the relatively enclosed installation environment of caves, NEC PA703UL+ adopts industry-leading CCT fully sealed internal circulation dust-proof and heat dissipation technology as well as conflict air cooling technology, ensuring good heat dissipation and dust prevention for the LCD panel light engine. However, to ensure long-term stable operation of the projector, relying solely on its own heat dissipation is not enough. The smart projection housing NH10K, designed specifically for PA703UL+, has an airflow design that perfectly matches the projector's heat dissipation structure, ensuring that internal heat does not accumulate, thus achieving constant temperature heat dissipation and safeguarding the stable operation of the projector. Moreover, NH10K also features IPX5 level water resistance, making the PA703UL+ projector fearless against water erosion. A remote intelligent monitoring system allows real-time understanding of the status of the housing and the projector. It is precisely based on the three advantages of NH10K's secure protection, intelligent heat dissipation system, and intelligent monitoring system that ensure the projector's long-term stable operation in complex and variable cave environments.

NEC has designed IP65 all-weather outdoor protection housings for its multiple projector models, known as the NH series.

　　In the face of the special situation of complex installation angles in caves, NH10K also provides an ideal solution. NH10K has no installation angle restrictions, thus greatly facilitating the complex installation in caves. As a customized enclosure, NH10K is designed with 12 intake and exhaust vents, which can be freely combined according to different projectors and different installation angles of the enclosure, ensuring efficient ventilation and heat dissipation. To address the difficulty of projector maintenance, NH10K is specially equipped with a rail system, which can be easily pulled out from the side or front, making the installation and maintenance of the projector convenient.

　　This treasure of a water park is the result of a two-year renovation and upgrade by the Wuhan Youth Palace, bringing a new cool and refreshing water play experience to the citizens of Wuhan. Currently, with the rise of 'theme park fever,' various theme parks are actively seeking innovative and distinctive development. Outdoor projection shows using high-quality projectors and customized outdoor enclosures will become an increasingly preferred solution for the renewal and upgrading of many theme parks. NEC's extensive range of projection products, combined with customized NH series professional outdoor protection enclosures, will provide more outdoor projection customers with more stable and reassuring one-stop outdoor projection solutions, empowering diverse tourism formats through light and shadow technology and creating new cultural tourism landmarks in urban areas.
