Light primer of Exhibitions and fairs
1. Different Kinds of light
Filament lamp
The light emitted by a bulb is a yellowish, warm and atmosheric light. In connection with a reflector lamp, these lamps are well suited to evoke idyllic situations. In addition to that, these lamps are good value and are therefore often used as all-purpose light. The light efficiency is not very high and the bulb gets rather warm.
Halogen lamp
Halogen lamps are an advancement of bulbs. This kind of lamp provides a light that is more white than that of bulbs and is experienced as brillant. This light is perfectly suited for spotlighting objects of every kind. Especially products pertaining to the life style sector are being brought to life in a nice way.
Halogen lamp low voltage
This lamp is operated at low voltage (12V), which results in a very small filament. That enables perfect focussing of the lamp. Low voltage spots provide very exact focussing and the most brilliant light colours. This lamp is especially useful for crucial exhibits like antique furniture, paintings and jewellery. It is also used in display cabinets.
Fluorescent lamp
Due to its make, this kind of lamp is well suited for area lighting. The colour quality of fluorescent lamps is below that of halogen lamps. A big advantage is the low production of heat. Thanks to their size and surface these lamps are often used for light boxes, the edges of steps or for indirect lighting.
2. Allocation Of Light
For a perfect light for every exhibit, not only the choice of lamps is crucial, but also the perfect allocation of light.
Spot lights have a very small angle of beam spread of apprx. 10 to 30 degrees. This results in a tight focus of the light on one exhibit. Also, all the heat emitting is concentrated on the exhibit. The inevitable shadows have to be taken into account, too. But this can also be used for setting the scene.
Flood lights are the exact opposite of spotlights.. Their angle of beam spread lies between 30 and 120 degrees. Floodlight also inevitably produce shadows. But most of the time, floodlights are being used on high output to light rather large areas.
Homogeneous Light
In order to avoid shadows, the light sources have to be arranged evenly across many positions. This can be accomplished by means of indirect lighting (illumination of surfaces). This is seldomly of use for fairs and exhibitions, thought, for example behind blinds, lighting of pedestals and exhibition cases.
3. Light Output
"No selling without light". This is a motto that has proven itself already for many times. Newcomers and lowcosters try again and again - but they fail. Because man is being guided by light, it is of great importance to provide enough light on the entrace side of every booth. People automatically head towards bright place. The lights of the exhibition halls are usually turned on, but they are, however by far not sufficient.
The minimum value for lighting with bulbs or halogen lamps is 25 watts per square meter. An exhibition booth with average lighting uses 40 to 60 watts per square meter. 100 watts per square meter should not be exceeded, as them heat production could hamper booth quality.
4. Light Arrangement
The best lamp is of no use if the visitor is blinded by the light because of spotlights being incorrectly set or arranged. The light should always be set in way as to illuminate from the onlooker towards the exhibit. If an exhibit is being illuminated too much from one side, another spotlight from another angle can be used to compensate. By that, the resulting cast shadows will not seem to be as hard. For paintings or similar exhibits hanging on the wall we provide extension arm lights. Their arm can move the light spott 500 to 700 milimeters away from the wall, providing ideal lighting.
