Among the European countries, Germany is especially known for its active promotion of environmental protection. Not only has energy conservation been promoted through various methods, but also an ambitious goal has been put forward. "By 2020, the ratio of renewable energy in total electricity consumption will gradually increase from the current 20% to nearly 40%." .
In the world's largest international trade fair "Light + Building 2012" (for the 196,000 participants) for lighting and building automation, held in Frankfurt, Germany's economic city, from April 15th to 20th, this year, The implementation of energy-saving lighting technology and lighting products is unprecedentedly active.
In the show, lighting control solutions and design lighting fixtures with new light sources are particularly eye-catching. In this article, the author wants to introduce these two points separately.
Lighting control applications are not limited to energy saving
In order to further develop the energy-saving performance of new light source LED and OLED (organic EL) lighting, the use of technology and equipment for lighting control, user-friendly software, etc. will play an important role.
In recent years, creating a healthier and more comfortable working space in an office building has become a worldwide goal. Office-related environmental factors are rapidly changing, using environmental performance assessment and certification systems such as LEED (Leadership in Energy and Environment Design) developed and operated by the US Green Building Council (USGBC), and building digital networks (Digital Networking). As a product to cope with this situation, ZUMTOBEL (Austria) has released a control system "TUNABLE WHITE" that combines dimming and color temperature conversion. According to the company, flexible lighting control that adapts to sunshine conditions, the number of workers, and workplace changes can be achieved by using a light sensor that has been used in the past.
At this year's trade fair, a large-scale lighting management system for outdoor public spaces that consume large amounts of electricity and use street lights and road lighting is also attracting attention. This is an area that has not been displayed in the last trade fair.
"City Touch" released by Philips (PHILIPS, the Netherlands) and "Street Light Control" issued by Osram's SITECO (Germany) can be switched on according to the time of day, the traffic volume of vehicles and people, and the use of the area. Lights and lights are turned off, and uniform illumination is adjusted by dimming. Since the lighting fixtures that can be used are not limited to the same manufacturer, they are highly versatile. In addition, in terms of maintenance, there are also advantages such as easy to find faults.
The product introduction of Philips' outdoor lighting control system "City Touch" has attracted much attention. The software used for control displays the location of the street light on the map.
Osram's outdoor lighting control system. In addition to being controlled according to the "DALI" standard, the system can also use different control methods ("Step DIM" and "Astro DIM").
Osram's outdoor lighting control system. In addition to being controlled according to the "DALI" standard, the system can also use different control methods ("Step DIM" and "Astro DIM").
According to Philips, the system has been adopted in the city of Tilburg in the Netherlands and in some towns and towns in the UK and Germany. It is being explored that there are also a few local governments in the future. It should also be forgotten that, in addition to the functional aspects of energy-saving measures, “slightly dim the outdoor lighting on the full moon night (to appreciate the moonlight)†(extracted from SITECO's product information), this and nature The use of environmental coexistence can also be achieved by adopting these technologies.
The control system that follows the DALI standard is eye-catching
As mentioned above, various options related to lighting control appeared at this year's "Light + Building" trade fair. However, the above-mentioned ZUMTOBEL's office interior lighting control system, large-scale lighting management system for streetlights and road lighting is representative, and the lighting control technology adopted by many companies is based on the international standard "DALI" (Digital Addressable Lighting Interface). Ballast.
Although the DALI standard was previously mainly used for lighting control in indoor spaces, in recent years, the technology has once again become the focus of attention for energy saving. By equipping DALI ballasts on individual lighting fixtures, each lighting fixture has an address. Therefore, it is possible to perform flexible lighting control such as turning on, turning off, and dimming in units of individual lighting fixtures without being limited by circuit design, which is a feature of the technology.
On the other hand, there is a "DMX (DMX512-A)" interface among communication interfaces often used in performance lighting such as RGB mode LED color illumination. i Guzzini (Italy) exhibition area boldly arranged "Luminous Floor", Philips uses the textile lighting system "Luminous Textile" and other displays, is the use of DMX interface, open walls such as walls, floors as a "canvas" The color illumination performance of various color and subtle tones has been sensation, which makes the audience feel the feasibility of the new space design.
