Mounting and Suspension Systems

Mounting and suspension systems are important components of an exterior lighting system, as they are responsible for holding and positioning the fixtures in place. Here are some common mounting and suspension systems for exterior illumination:

1. Wall-mounted brackets: Wall-mounted brackets are commonly used for exterior lighting fixtures such as sconces or floodlights. These brackets can be installed directly onto a wall or onto a mounting plate, which is then attached to the wall.
2. Pole-mounted systems: Pole-mounted systems are commonly used for street lighting or parking lot lighting. These systems include a pole or mast that is anchored into the ground, along with a fixture mounting bracket that is attached to the pole.
3. Ceiling-mounted systems: Ceiling-mounted systems are typically used for outdoor covered areas such as porches or patios. These systems include a bracket that is attached to the ceiling, along with a suspension system that holds the fixture in place.
4. Bollards: Bollards are short posts or pillars that can be used to mount small lighting fixtures. Bollards can be installed into the ground and are often used for pathway lighting or to mark boundaries.
5. Wire suspension systems: Wire suspension systems are commonly used for large-scale outdoor lighting installations such as decorative lighting displays or event lighting. These systems include a wire cable that is suspended between two anchor points, along with a suspension system that holds the fixture in place.
6. Columns upto 15 Meters : These columns can be manufactured from steel, concrete, aluminium, glass reinforced plastic or wood.

7.Hinged Steel Columns : These columns are available for mounting heights up to about 25 metres, and they allow the luminaires to be brought down to ground level for maintenance and lamp replacement.

8.High Masts : These are made from hollow steel, aluminium welded sections or concrete and can be used for mounting heights up to 50 metres or more.

9.Building or Wall Mounting Luminaires : Considerable savings can be achieved if use can be made of these.
