lesser aesthetic floodlighting

2012-Aug-27,08:00

Floodlights need to meet two very specific architectural requirements: they need to perform well in terms of area lighting requirements as well as being aesthetically in keeping with the function of the area. dab5d56ck To illustrate: a marine loading dock would have a lesser aesthetic floodlighting requirement than a stadium or public roadway.

Ground level LED floodlights are often to light-up landscaping and architectural features. Such highlighting helps bring focus to specific structural details because light instinctively attract a viewers attention. It helps to avoid trying to highlight too many architectural elements at once because this creates the visual dissonance and destroys the "dramatic" appeal of focused lighting.

When choosing lighting for buildings it is important to be aware that under lighting the base and upper levels of a structure while focusing lighting on a mid-section of it can create a "floating" effect which is rarely visually appealing. A good rule of thumb would be to use smaller washes of lighting for the entire structure and to couple this with stronger LED floodlighting to emphasis desired feature or features.

Whether you are lighting a retail park, a parking lot or a small office complex you will want to maximise the amount of "usable" light (i.e.: light that falls on structures and pathways) and minimise light that spills into unused areas such as reflection to the sky or light ****tered onto neighbouring areas. It is also useful to note that a high percentage of reflected light is reflected upwards. This can be exacerbated when up lighting a feature. It is best to avoid up lighting when the physical material that a structure is built on has a highly reflective surface.

Curved reflectors in an LED floodlight will result in a conical beam of light which is useful for targeted lighting. Rectangular reflectors form a more ****tered bean and are often used to light up larger areas such as parking lots or sports fields. Also worth noting for such large areas: The costs of installing and maintaining secure lighting in large areas will be of primary concern because they are typically more expensive. Additional portions such as louvres and visors will also affect the shape of the beam.

For parking areas and roadways LED floodlights will usually be set atop high poles and it is best to choose energy efficient, strong ****tered luminaries to maximise ****ing between the units. Fewer poles incur lower installation and maintenance costs and the selected wattage (250 watt or less) will directly influence maintenance costs.

It is recommended to select a lighting supplier that can advise and substantiate the appropriate units for each individual lighting purpose.
