Peru’s Stadium Façade Lighting Responds to Football Fever

13 Sep

Cinimod Studio and an international design team developed an interactive LED lighting system for the Peru National Stadium that captures the audio levels of the stadium crowd and depicts it visually on a dynamic façade.

Cinimod Studio, a London, UK-based architecture and lighting design firm, has delivered an interactive lighting-control system for the Peru National Stadium in Lima. The system gathers the crowd’s noise levels in real-time and translates the audible signal into a visual map that is depicted on the façade’s lighting display.

LED-lit façade

Cinimod Studio worked as part of an international design and delivery team including lighting designer CAM and software designer ArquiLEDS, both of Lima, Peru; e:cue, a lighting control company based in Paderborn, Germany; and Traxon Technologies, a lighting designer based in Hong Kong.

The façade-lighting system begins with a network of customized microphones deployed along the stadium’s roof line. This data is then processed by Cinimod’s custom processing hardware and software located in the stadium’s main communications room. The audible data is analyzed using mathematic calculations and self-calibrating algorithms. The software then communicates a “mood state” to the e:cue lighting controller, which transmits the relevant DMX control signal to the lighting fixtures on the building’s facade.

The external lighting scheme is designed to integrate seamlessly within the architectural framework of the building. The majority of the lights are laid out as fans of flames that wrap upwards around the form of the structure. The façade’s patterns vary in color, speed, brightness and scale.

The software runs perpetually, constantly evaluating the mood, which varies between celebration at one end of the spectrum to disappointed at the other.

The façade’s patterns

The main mood states include: 1) Boring, a neutral mood; 2) Excitement, accompanying a surge in crowd noise and pitch; 3) Celebration, typically triggered by a goal and followed by a further rise in noise level; and 4) Disappointed, triggered by an excited state followed by a rapid decline in noise level.

The scale of the stadium façade necessitated a very large array of color- and pixel-addressable fittings. The lighting controller provides 62 universes of DMX lighting control output.


LED Traffic Signal Lighting from Osram Opto Semiconductors Provides Safety for Pedestrians

07 May

With the help of “Light Line”, a warning light installed in the pavement, crossing the road becomes safer for pedestrians: in parallel to the switch function for the LED traffic light, “Light Line” uses a red or green signal to show whether the street can be crossed without danger or not. The warning light was developed by DSTA, a Spanish company that designs and manufacture LED solutions for traffic, lighting and transports. The signals in the various colors are provided by light emitting diodes from OSRAM Opto Semiconductors.

Particularly at less busy traffic periods, pedestrians often step onto a road crossing when the traffic light has already switched to red. This does not always have a happy ending. To reduce the resulting number of accidents, DSTA, the Spanish producer of light systems, has developed a solution with its “Light Line”, signalling to the pedestrian directly at his or her feet, additionally to the normal traffic light, whether it is possible to cross without danger. The warning light is integrated into the pavement and functions on a synchronous basis with the traffic light switch system: if the traffic light switches to red, the “Light Line” also switches to red and warns the pedestrian. As soon as the traffic light is showing green again, the “Light Line” also turns green. The double light signal is intended to bring about a higher level of attentiveness among pedestrians, prompting them not to cross the road when the signal is red, even if no vehicles are to be seen at that moment. To get a rapid and reliable light signal, DSTA is opting for red and green Golden Dragon LEDs from OSRAM Opto Semiconductors. These provide operate times in the nanosecond range; thus there are no delays in switching over and there is a gain in safety for the pedestrians.

Greater safety at the path of protection

Golden Dragon LEDs from OSRAM Opto Semiconductors can make avail of all their strengths in the innovative Light-Line solution: LEDs are very robust, defying jolts, wind and weather, as well as accumulations of dirt on the pavement. Thanks to the small construction size of the modules, it is possible to have very flat designs for the luminaires, a factor which also offers the opportunity of a problem-free retrofit installation. The decisive factor for DSTA was the low level of maintenance workload required by the LED: depending on environmental conditions, Golden Dragon LEDs have an average operating lifetime of up to 100,000 hours. This keeps maintenance costs very low and traffic is scarcely influenced as a result. Thanks to its low power requirement, in providing a high quality of light, the product is also a particularly efficient solution.

First test installations of the “Light Line” are in place in the Spanish cities of Burgos and Terrasa; further projects are to be launched in the near future. “Cost efficiency is an important factor, which is why more and more municipalities are opting for this LED system when it comes to pedestrian safety“, observes Ramón Fernández Morales, Business Development Manager at DSTA. “Golden Dragon LEDs are particularly economical and are the optimum solution for us, thanks to their energy efficiency and their low maintenance requirement.”


LEDs Light Inside and Outside of Asian Games Venue

20 Jan

LEDs take center stage literally at the Asian Games as Seoul Semiconductor products provide stage lighting and Osram provides external venue architectural lighting.

Seoul Semiconductor Z-Power LEDs lit the stage at the 2010 Asian Games opening ceremony in Guangzhou, China. Osram LEDs provide decorative and architectural lighting on the outside of the new Haixinsha Square venue that hosted the opening ceremonies and will host other events including the games’ closing ceremonies.

Seoul Semiconductor lights Asian Games stage

Golden Sea Professional Equipment, a Seoul Semiconductor partner, provided the Z-Power-based LED solid-state-lighting (SSL) system that illuminated on-stage performances at the Asian Games opening ceremony. Brian Wilcox, VP of North American Sales for Seoul Semiconductor, said, “Featuring rich color, the Z-power Series provides exceptionally consistent lighting for a more pleasant viewing experience, and improves visual detail.”

Golden Sea chose the Z-Power series based on the light quality afforded by the LEDs that generate white uniform light that achieves an 80 rating on the color rendering index (CRI) scale. Golden Sea also noted that the LEDs create outstanding evening visibility for a comfortable and safe environment.

Energy efficiency and long life are recognized advantages of SSL in general illumination applications, and those same advantages played a role in the SSL deployment at the Asian Games. The Z-Power series delivers 100 lm/W at 350 MA drive current, and the LED stage lights can last 100,000 hours – as much as 130 times longer than conventional lighting, according to Seoul Semiconductor. The LED lights also contain no toxic substances and fit this year’s Asian Games theme of “high-tech, energy saving, going green.”

“As a leading supplier of high-quality lighting in mainland China, we strive to bring the most advanced, most value-added lighting solutions to our customers,” said Zhang Wei Kai, president of Golden Sea. “The Asian Games is one of the largest events in China this year, and I am sure our partnership with Seoul Semiconductor was instrumental in enabling us to secure this monumental win. Their LED lighting products are best-in-class, featuring excellent technology, energy efficiency, and are completely safe for the environment. It is always a pleasure working with them, and we looking forward to tightening our relationship in the future.”

Lighting Haixinsha Square venue

While Golden Sea LEDs light the stage inside the venue, Osram Oslon SSL LEDs provide the multi-colored architectural lighting on the outside of the new Haixinsha Square stadium. The project includes around 200,000 LEDs integrated in 3200 floodlights.

Osram LEDs provide architectural lighting

The architectural lighting utilizes a mixture of Oslon SSL amber/green/blue LEDs in some flood lights along with warm white LEDs in others. The lights yield different combinations of colors to highlight the structure of the outside of the stadium.

Guangzhou Joinmax Display Technology Limited installed the lighting system. General Manager Jiansheng Chen said, “We have experimented with a few designs and have finally opted for bidirectional asymmetric lens design and DMX online system which can make the whole lighting system more easy to use and to create dynamic lighting effects.”

“We are very excited that our Oslon SSL LEDs are part of the Asian Games opening ceremony,” said Kai-chong Cheng, Marketing Director of Osram Opto Semiconductors Asia Ltd. “Millions of visitors at the venue and viewers through television broadcasts will see how well these amber, blue, green and warm white LEDs deliver a colorful profile of the stadium.”

The Asian Games began on November 12 – the day of the opening ceremony. The games will run through November 27th with more than 11,000 athletes from 45 nations competing.


Philips’ Lamps Make Super Bowl Celebration Glow with Energy Efficiency

26 Oct

Capable of projecting customizable colors onto the underside of the crown of the Tampa, Florida, stadium, 70 programmable floodlights use just 290 W per fixture.

Super Bowl lights

Raymond James Stadium, Tampa’s host venue for the Super Bowl, has been temporarily illuminated with state-of-the-art LED technology as part of a city-wide beautification effort for the championship game on February 1.

From January 27 through game day, the stadium is being illuminated from dusk until dawn with Philips ColorReach Powercore LED floodlights, turning it into a dynamic focal point for Tampa residents and visiting fans.

Design firm Infinite Scale Design was responsible for designing and branding the overall look of the city of Tampa for Super Bowl XLIII. Working with lighting designer Dall Brown, they chose to accentuate the stadium’s exterior crown with colorful, customizable lighting.

Approximately 70 ColorReach Powercore fixtures were used in total, with just two required to evenly illuminate each 40 by 80 foot bay. Mounted on a concrete cross beam from within the stadium, the fixtures project light onto the underside of the stadium’s upper 30 rows.

Super Bowl stadium

Each fixture is individually programmable and can produce millions of colors and color-changing effects, which enables the stadium to display the colors of the opposing teams as well as providing dazzling lighting effects.

Capable of projecting over 500 feet, the ColorReach Powercore fixtures make the stadium visible from the air and from multiple viewpoints across the city. The fixtures were supplied by LED Source and programmed and installed by local Tampa entertainment solutions provider, Bay Stage Lighting.

“The Super Bowl is considered by many to be the most important sporting event of the year, and we wanted to create a visually striking look for the city that matched the excitement of the event,” said lighting designer Dall Brown.

Philips floodlights in action

In addition to generating dynamic effects, ColorReach Powercore supports the National Football League’s recent efforts to make the Super Bowl event more “green.” The temporary lighting scheme requires minimal energy; just 290 W per fixture. Even when operating at full intensity, ColorReach Powercore consumes less than half the energy of a typical coffeemaker. By comparison, the traditional metal halide fixtures typically used in such exterior projects consume 1,600 W each and require gels to produce colored lighting.

Other Philips Color Kinetics installations in entertainment and sporting venues include Boston’s TD Banknorth Garden and Bank of America Pavilion, Los Angeles’ Hollywood Bowl, Milwaukee’s Marcus Center for the Performing Arts and Sweden’s Globen Arena.


Architectural LED Lighting Installation at Kremlin Palace Features Over 200,000 DMX Channels

07 Oct

The State Kremlin Palace in Russia is now home to an architectural LED lighting installation that features over 472 DMX universes.

The main auditorium of the State Kremlin Palace in Moscow recently underwent an architectural LED lighting remodel that features RGB LED panels, supplied and installed by Divolight, which are centrally controlled by an e:cue lighting control system.

The auditorium is encased by towering walls, which is where the LED panels were installed. The panels create two large curvilinear LED screens, measuring 15mx60m.

This new multidimensional environment includes over 472 DMX universes (241,664 DMX channels) from e:cue, making this installation one of the biggest LED control projects worldwide. Control is achieved by 236 e:cue Butlers, fully orchestrated by a Media Engine 2 and a Video Control Server (VCS1) capable of playback of multi-layered videos, images, scrolling or static texts. Additionally, e:cue’s Excite+ was used as a DMX-to-USB interface, allowing necessary integration of a lighting control desk into e:cue’s central control system.

The architectural LED lighting remodel, led by architects from the studio OTASH, was meant to integrate modern elements into the existing architecture of the Hall, as well as to create a multifunctional space. OTASH arranged the LED panels to construct an entire environment for visitors to experience, instead of simply directing sole focus to one portion of the space.

Formerly known as the Kremlin Palace of Congresses, the State Kremlin Palace has been a famous center for Russia’s political and cultural life. Erected in 1961 and intended for use as a modern arena for Communist Party meetings, congresses, performances and concerts, State Kremlin Palace contains over 800 rooms, and its central space remains one of Europe’s biggest auditoriums with seating to accommodate 6000. Today the space is used primarily for concerts and ballet performances, is home to Kremlin Ballet Theatre, and acts as a second stage for the Bolshoi Theatre.
