## Symbol convention

Convention: IEC
Form: Floodlight
IEC 60617 installation-plan style (architectural and topographical installation symbols); independently drawn, not certified IEC geometry or a database identifier.

Plan mark for a floodlight that lights an area, drawn as a luminaire with a widening beam.

## In plain English

### What does Floodlight plan mark mean?

Floodlights for yards, sports areas, facades and car parks are drawn as a luminaire mark with diverging beam lines, showing a wide spread. The aiming direction is shown by the beam and mounting height is noted.

### A simple example

Floodlights are typically controlled by a photocell, time switch or contactor because the load is large. The plan symbol often sits on a building wall or a pole and is linked to that control scheme. Beam lines are indicative. Photometric calculations, not the symbol, confirm coverage.

### What the drawings help you do

Note aiming direction and mounting height. Find the control scheme. A spotlight has a single narrow beam arrow; a floodlight shows a diverging beam.

### This particular reference

Plan mark for a floodlight that lights an area, drawn as a luminaire with a widening beam. A spotlight has a single narrow beam arrow; a floodlight shows a diverging beam.

### Terms

- Normally open / normally closed: The contact state in the normal condition defined for the drawing.
- Coil: A wound conductor that can produce a magnetic field when energised.
- Schematic: A drawing showing function and connections rather than physical appearance.

## How to read it

- Note aiming direction and mounting height.
- Find the control scheme.

## Information to show or reference

- State mounting height and tilt.
- Show controls.
- Reference photometric design.

## Important distinction

A spotlight has a single narrow beam arrow; a floodlight shows a diverging beam.

## Facts

- Graphic cue: Diverging beam lines
- Typical control: Photocell and contactor
- Exact standard graphic: Not reproduced here; confirm the form against IEC 60617 and the project legend
