Shanghai Greenhouse Garden, hailed as an urban utopia, is located at the prime central position of the Shanghai Expo Cultural Park. Adjacent to the Central Lake and backed by the Twin Hills, it covers an area of 22,000 square meters, making it one of the few large-scale greenhouse gardens in Asia.

Shanghai Expo Cultural Park is located in the Pudong New Area of Shanghai, standing in the "prime location" along the banks of the Huangpu River. In the heart of the city's high-value real estate, a 22,000㎡ super indoor garden has been created. The Cloud and Mist Canyon Hall utilizes the LTECH DMX512 decoder to integrate natural lighting, creating an urban utopia.

Glass forms the shape of auspicious clouds

while light and shadow embrace the forest

The greenhouse garden features three main halls: Hall 1 – The Sea City Shazhou, Hall 2 – The Cloud Forest, and Hall 3 – The Cloud and Mist Canyon
From an aerial view, the structures resemble clouds in various shapes Built with glass as the primary material, they create a transparent visual effect while dynamic lighting and lush greenery together reveal a vibrant and lively atmosphere

The play of light and shadow in the greenhouse is not only reflected on the plants
but also spills "out of bounds" through the transparent glass curtain walls The entire greenhouse garden shines like a dazzling gem Radiating brilliance in the city

Creating breathing light

That merges and harmonizes with nature

In the third "Cloud and Mist Canyon" themed hall
There is a 30-meter "Floral Propagation" interactive art installation Inspired by the plant species Belea Palm It is made up of 729 transparent acrylic panels Allowing the flowing light to intertwine within Mimicking the natural phenomenon of pollen dispersion

▲ Lighting Effects of the Art Installation

LTECH DMX512 decoder offers selectable PWM frequencies: high and low
Gray levels can be set to either 16-bit (65536 levels) or 8-bit (256 levels) Allowing for flexible, dynamic lighting effects It is tailored to naturally replicate the Tyndall effect in the forest Where light scatters through particles in the air

The "Floral Propagation" art installation is divided into 81 groups
Each consisting of 9 transparent acrylic panels The LTECH DMX512 decoder features 4 types of DMX interfaces Making the wiring process more convenient and efficient

▲ Each Decoder is Installed in a Distributed Electrical Box

The entire art installation cascades down from the second floor of the garden
Spanning across the hall’s ceiling LTECH DMX512 decoder boasts ultra-high signal transmission efficiency and strong anti-interference capability Making it stable and efficient for large-scale projects

DMX512, Triac, 0-10V, and DALI are the four most commonly used dimming methods in the lighting industry. Among them, Triac and 0-10V are analog dimming methods, while DALI and DMX512 are digital standard protocols. In static dimming and color-tuning scenarios, DALI has already proven excellent performance; However, for this project, which requires both static dimming and dynamic color control, DMX512 outperforms DALI: DMX512 offers faster rates, creating quicker changes and effects. It is the preferred protocol in stage performances, KTV, and other venues. Its versatility makes it suitable for any setting, And it remains popular in the European and American markets.

As early as the beginning of the LED lighting development, LTECH introduced DMX technology to the domestic LED industry, Developing and producing DMX512 decoders. The LTECH DMX512 decoder uses advanced decoding technology, Converting the internationally popular DMX512 digital control signal into constant current/constant voltage PWM signals and SPI (TTL) digital signals to drive LEDs. The DMX decoder is controlled by a DMX512 console, allowing for 0-100% dimming or various effects, while controlling single-color, bi-color, RGB, RGBW lights, and more. LTECH has always adhered to independent innovation, developing a full range of high-quality DMX products. Its stable and efficient product performance has led to LTECH DMX products being exported worldwide.

After 21 years of dedication, LTECH has developed a comprehensive range of "smart home," "smart power," and "LED control systems" lighting products. LTECH also offers sub-brand products such as the L-BUS lighting control system, LTSYS smart power, and Xiaolei smart home,and has built its proprietary L-Home IoT cloud platform. These products are widely used in numerous smart home, smart office, and smart hotel projects both domestically and abroad. Moving forward, LTECH will continue to present more diverse engineering cases.
