German tunnel uses OSRAM's Golden DRAGON LED

The autumn of 2008, the A71 highway Th u ringer Schm u cketunnEL tunnel will become the first in Germany and Europe's longest one by LED tunnel lighting. Currently, one of the holes in the tunnel began to try LED lighting. All lighting lamps are using OSRAM's Golden DRAGON LED products, and Dellux Technologies has also developed a dedicated tunnel lighting lamps. Dellux lighting and OSRAM's LED light source is the perfect combination, providing life of more than 130000 hours (15 years) and almost no maintenance of lighting equipment. With Dellux's patented "LED efficiency decreased compensation technology" (LED Degradation Compensation Technology), the installation of lighting power consumption than ordinary 70W high-intensity discharge lamps to reduce 30%.

Dellux technology combined with OSRAM's Golden DRAGON LED products, to ensure the shortest 15 years of lighting life, and the brightness level will not fall. OSRAM Opto Semiconductor solid-state lighting division marketing director Michael Fiebig said: "this is a big advantage of lighting products, especially for the tunnel lighting is even more so, because the maintenance and replacement of lighting is not only costly, but also caused great inconvenience to the exercise of the vehicles in the tunnel, but also endangers the safety of the driver. The light source and lighting fixtures used in this project are more stringent than the strict safety standards for tunnel lighting. Another big advantage is that the long-term test results show that OSRAM LED lumen descent curve is stable, rarely used during the color position offset. OSRAM excellent lighting source, coupled with the patented Dellux lighting efficiency reduction compensation technology, so that the shortest life of lighting lamps can be up to 130000 hours, and always maintain the necessary lighting brightness. "

Light up the tunnel to achieve high brightness

The brightness of the semiconductor light source can be adjusted, so that the brightness of the light source can be adjusted to provide the appropriate lighting brightness in the tunnel, whether in the day or at night. During the day, the tunnel required a brightness of 4.65 cd/?; while the night only required a brightness of 0.8 cd/m?. During the day, the average power consumption of lighting in the tunnel is 70W, while the night is only an average power consumption of 12W can provide enough brightness lighting. Overall, compared with the lighting system using high intensity discharge lamps, the Dellux lamps per year OSRAM LED light source can save 10000 kWh of electricity, equivalent to a reduction of more than 30% of the energy consumption.

Intelligent lighting concept extends the life of lighting

As an expert of the tunnel lighting, Dellux has for tunnel lighting applications (such as Schm cketunnel tunnel) launched intelligent lighting concept, give full play to the superiority of LED products Golden DRAGON, and with a custom electronic circuit and software, greatly prolongs the service life of a lighting system. Dellux Technologies, vice president of European business development Wolfgang Medenwald said: "we have installed a backup LED in each lamp to compensate for the loss of brightness caused by pollution and efficiency degradation. At the same time, we will all LED operating current is set to 85% of its rated current, in order to achieve higher efficiency and maximum durability. Despite the harsh conditions of the tunnel, the use of our patented technology to reduce the efficiency of compensation, still can guarantee the required lighting brightness, life expectancy of at least 15 years.
