Festival of Light and videomappingu released its trailer. The main representative of a short film theme songs is in Olomouc, equally important is the light that appears familiar and lesser known places of the city night.
Motive jingles festival is the light that comes into the mysterious Hana metropolis. Directed by Stephen camera captured the night city Vodrážka surprised beam, which roams the streets and sleeping midnight last amazes pedestrians, until it finally finds its target on the facade of City Hall. It lights up with spectacular lighting and projection videomappingovou people conceal breath over her new face.
"We wanted a jingle best capture the essence of the festival, which indicates the historical center of the city literally in a different light," says Kamil Zajicek, director of the festival, adding, "in the title roles we occupy in Olomouc as a venue for the festival, in a scenario could also be a light which is his symbol, and without which it could not be videomapping spectacular light installations. The festival is put on the square in Olomouc unique light costume. "

FESTIVAL OF LIGHT AND A LECTURE VIDEOMAPINGU ROGER NARBONNIHO
Thursday, August 25, 2011 9:19
Festival of Light and videomappingu, which will be held in the last week of September in Olomouc, introduces the first in European competition videomappingu. Three competing teams - from the Czech Republic, Poland and Hungary - the jury will present their art and historical palaces rozpohybují Olomouc square.
You know what it is videomapping?
Have you ever seen a building that came to life after dark, magic, animated the lights and told his story? So it is videomapping - visual art that uses the projection as the facades of houses and translates them to 3D models and animations created tailor-made buildings. Real scenes can exposure to light, darkness and film sequences to change its shape, move and be part of the light theater.
Philips, as a co Festival builds on last year's first festival of light held in Jablonec nad Nisou. Philips LED lighting systems Haná metropolis, which boasts the second place, as the number of historical monuments in our terms (after Prague), with lighter installations. Philips Lighting Installation revive Olomouc Upper Square and will be on display throughout the festival.
Philips also holds patronage of the professional part of the festival, which is dedicated to creating a pleasant environment in our towns and villages with lights. The festival will hold a major conference on the topic "Light for our city." The conference is primarily intended for mayors, city administrators lighting, architects and lighting designers.
The main highlight of the program will be a lecture, "Strategies in Urban Evolutions and lighting," the world's leading lighting designer, Roger Narboniho of Concept, which stands for light such as the concept of Notre Dame or the castle of Chambord.

INDUSTRIAL LIGHTING DUROSITE 14 000 LM
Wednesday, August 24, 2011 0:00
LEDs penetrate into ever new application areas. One relatively new area is the lighting of large indoor spaces. Last month the company introduced the American DIALIGHT , innovative range of lighting DuroSite intended for lighting of large indoor spaces such as industrial or warehouse buildings, premises, supermarkets, etc. These lamps are installed luminous flux 14000 lm and specific output of 93 lm / W. With these technical parameters are no longer able to compete with metal halide lamps, which were common in these applications, light sources. The big advantage of LEDs is in this case, long life time, which significantly reduces the cost of relatively intensive exchange of light sources.
The innovative range of lighting DuroSite a row against the original lighting by 20% more luminous flux at the same wattage, which retained the temperature conditions for which designed the original lighting. Luminaires are designed for use in both internal and outdoor spaces (eg ports). Besides the high IP66, they also share a zero flux in the upper half-space and a certificate of IDA (International Dark-Sky Association).

LIVING THINGS
Wednesday, August 17, 2011 0:00
The team of young designers living things introduced interactive lighting Jolana Šornerové Fireflies.
Until about nothing happening, Fireflies rest. When the sensor records the movement, fireflies come alive, stretched wings and shining on the road in the dark.
Last year he won the National creature jeich project award for student design. Was introduced Designblok or at the Czech Center in New York in the exhibition New Go (o) ds!.
The creature appears to live its own life and the audience is able to induce an emotional reaction. This alien is blessed with a working lamp artificial intelligence that directs it into the darkest places of space. Tirelessly posing as darkness, but it terminates with his presence and moves away. The creature is thus condemned to endless wandering.
The basic building block is a creature Arduino, electronic, open-source platform based on the user a simple hardware and software. Arduino is able to perceive the surrounding environment using various sensors. Through various output peripherals can also affect the neighborhood.
Henry is a creature creator Vodicka, Graduate School of Applied Arts in Prague. Vodicka for his practice, an interactive designer says: "My goal is to facilitate their knowl interactivity or eliminate human labor. Creation, living things' to trying to deliver inanimate objects properties and abilities of animals. "

PARDUBICE EXCHANGE 1100 MAST
Friday, August 5, 2011 0:00
Pardubice plan to exchange 1100 public lighting poles. The exchange will take place 10 years with an estimated cost of more than 200 million. A third pole was installed before 1981, and is beyond life.
In Pardubice test since December last year in several places LED lights (see article) with lower power consumption, lower failure rate and longer life. Against conventional sodium metal halide lamps are more expensive. As stated by Director of Services of Pardubice Lea Tomková Agency ČTK, lights could be installed in the future, and will drop their prices.

CREE LED POWER COMPACT 152 LM / W
Wednesday, August 3, 2011 9:07
American Society unveiled a prototype of a compact Cree LEDs A direct replacement for incandescent light bulbs with the following specifications:
- luminous flux: Φ = 1330 lm
- power: P = 8.7 W
- specific output: η = 152 lm / W
- Color temperature: Tcp = 2800 K
- color rendering index: Ra = 91
Declared technical data was verified by an independent testing laboratory OnSpex. The prototype compact LED source technology is used under the name of the company Cree TrueWhite. It is a technology for obtaining white light that is operated by a red LED in combination with yellow LED with phosphor. This provides a warmer color tone of light with higher luminous efficacy than that achieved using conventional technologies for obtaining white light.
Introduced prototype shape differs significantly not only from the most compact LED sources but also from traditional light bulbs. According to available information, has a cylindrical flask and cooler, the cooler is much larger than the optical part. It seems that new resources would be required to reduce future forms and technologies of the past and could gradually move away from the shape of traditional bulbs.
Cree says that the prototype should meet the parameters required for obtaining prices for the twenty-first light source century, which is part of the competition L Prize announced the U.S. Department of Energy (DOE). However, the requirements for this category are not yet known, although it talks about the minimum required power density should be 150 lm / W. A certain problem in this case could be a cylindrical shape of the optical part, which does not create a uniform omnidirectional beam. Such is the nature of radiation is required in the above category, the competition for a replacement bulb 60 W
Compact LEDs with luminous efficacy of 150 lm / W may have a significant impact on energy consumption. Representatives of the company Cree believe that after the completion of such light sources and their introduction into production and sales can reduce power consumption in the U.S. by up to 16.5%, ie the level in 1987. The company has been announced by Cree, which could complete the development of superior light source and start its mass production.
