LIGHT FOR INDUSTRY AND ENGINEERING Logistics

Light for industry and engineering Logistics

In modern business, the importance of logistics is growing steadily. The quantity and quality of goods and services present ever new challenges for businesses. The distances are becoming greater, the delivery times shorter and increasingly more products require cool storage. Logistics halls in many cases have immense cubatures and there is also no daylight in frozen food stores. The energy requirement for the lighting is accordingly high. The most effective means for reduction of the running operating costs is an efficient lighting solution that minimises both the power consumption as well as...

• EDs achieve a long service life L • Intelligent thermal management guarantees a long life • Compact and durable product design minimises maintenance effort Zumtobel’s product range features particularly low-maintenance units that have a long service life and meet logistics requirements. Many luminaires in high bays are difficult to access, maintenance and frequent relamping are therefore very expensive. Reducing the need for maintenance has the added advantage of less frequent disruptions of working processes. With an average service life of 50 000 hours and a guaranteed end-of-life luminous...

Maintenance  Long service life “Again and again, we need to exchange defective or old light sources.” Durable LED luminaires are almost maintenance-free. The replacement of faulty lamps, ballasts or complete luminaires in partly inaccessible places, costs a lot of money and takes a lot of time and staff effort. In the case of LED luminaires, regularly replacing the light sources is no longer necessary, even after 50 000 operating hours the LED will still achieve a luminous flux of at least 85 to 90 per cent of the initial level. On the other hand, a HIT lamp will fall below 60 per cent of its...

Maintenance  Protection against the accumulation of dust “The environment is full of dust, and technically we would have to clean the luminaires regularly. In the case of high rooms, this is hardly possible.” Stack effect prevents dust from accumulating. A layer of dust on the luminaire surfaces has an insulating effect, possibly causing heated air to accumulate in the luminaire. Excessive temperatures reduce the luminous flux of the luminaire and may cause total failure of the luminaire. However, regular cleaning is difficult in the case of high rooms or during operation. The example of the...

Energy efficiency L • ED allows for a new dimension of efficiency that is increased even further through targeted lighting control of the lens technology incorporated • Thanks to the corridor function, the light is turned off when rooms or zones are not used • The availability of daylight offers the option to reduce artificial lighting Gebrüder Weiss GmbH, Lauterach | AT Architects logistics: Albrecht Bereiter Architekten ZT KG, Dornbirn | AT Architects headquarters: Cucrowicz Nachbaur Architekten ZT GmbH, Bregenz | AT Electrical consultants: Ingenieurbüro Hiebeler + Mathis OG, Hörbranz | AT...

Energy efficiency  Low power consumption “Electricity is getting ever more expensive. How can I reduce energy costs for lighting  ” ? Efficient LED technology provides for long-term reduction of energy consumption. Development of white LED Luminous flux 200 lm/W Many halls were put into operation 15 to 20 years ago and are in need of refurbishment. The technologies used are obsolete, the luminaires are not efficient and provide too little light. In logistics applications, light accounts for a very high proportion of operating costs. At least 20 per cent is accounted for by lighting. Modern LED...

Energy efficiency  Full amount of light only in case of anyone being present “The light is on permanently, in spite of the fact that the relevant area is occupied only occasionally.” The corridor function reduces the periods of use of the lighting, thus cutting electricity costs. Energy saving thanks to flexible illuminance and presence detection 100 % 80 % In logistics halls, there are very many storage areas that are permanently illuminated in spite of being used irregularly. In these areas, the corridor function can help reduce energy consumption substantially. Presence detectors will detect...

Lighting quality B • oth for high-bay storage facilities and large-area ware­ houses, Zumtobel provides luminaires with sophisticated light distribution • Innovative lens technologies and luminaire design provide for glare limitation in spite of high luminance levels Light strongly influences employees’ performance, making it possib­e to cope effortlessly with visual tasks and is therefore the l first consideration when it comes to lighting design. An adequate lighting level and good glare control are required in order to be able to concentrate on the work at hand and remain motivated. In addition,...

Lighting quality Higher illuminance levels “It is too dark in our picking and storage areas. The illuminance levels are not in conformity with applicable standards.” Higher illuminance levels facilitate work. Perfect light distribution minimises the safety risk. Frequently, maintenance intervals are not observed or the lighting system is a mix of HID luminaires that has grown over many years. Both situations will lead to illuminance levels that are much too low and not compliant with applicable standards. In addition, the use of rooms, and their layout, is changed repeatedly, for example additional...

Lighting quality  Glare limitation “Our luminaires dazzle the forklift drivers during loading and unloading of the high shelves.” Newly developed lens technologies provide for glare control and make the luminaires efficient. During loading and unloading of high shelves, it may well happen that the driver of the fork lift truck directly looks into the lighting. If excessive luminance levels cause glare, shelves may be hard to identify, which may cause mistakes. The new splitlens technology directs the light specifically into the side areas. Thereby, the central light pressure reduces and the luminaire...
