Before we discuss lighting

What is light?

What is light?

Light is electromagnetic radiation in thevisible range.

The visible range (at least for humans) isapproximately 400 to 770 nanometres.

Electromagnetic radiation travels at nearly300 million metres per second (the speed oflight) and includes radio waves, infrared,visible light, ultra violet radiation and X-rays(among others).

What is light?

The wavelength is established as speeddivided by frequency.

Frequency is the number of cycles persecond, or hertz.

Light is considered to have both properties ofparticles and waves. The smallest quantum(unit) of light is a photon.

What is light?White light is the combination of all of thecolour of the spectrum:

RedOrangeYellowGreenBlue

IndigoViolet

Colour

Colour is subjective - we can only assumethat we each see the same colours.

People who are colour blind perceive coloursacross a narrower range and cannot alwaysclearly differentiate between colours (most

commonly between red and green).

Colour andcolour temperature

Colour temperature is a comparativemeasurement. A light sources colour

temperature is the temperature an idealblack-body radiator would reach to match the

hue of the light source.

Measured in degrees Kelvin (the unit ofabsolute temperature), colour temperaturesabout 5,000 K are considered cool colours,while 2,700-3,200 K are considered warm.

Colour andcolour temperature

Daylight on a clear day - over 5,000 K

Tungsten halogen - approximately 3,200 K

Incandescent - approximately 2,700 K

Lux and lumen

Lumen is the measure of the amount of lightemitted per second by a light source.

Lux is a measure of lumen.

1 lux = 1 lumen per square metre.

Lux levels decrease as distance from the lightsource increases.

Luminaires (or lights to you and me)

Main types of luminaires:

IncandescentTungsten halogen

DichroicFluorescent tubes

Compact fluorescentsLEDs (Light Emitting Diodes)

Tungsten halogen general purpose luminaire

Type of tungsten halogen bulb

Tungsten halogen reflector luminaire

Dichroic bulb (Tungsten halogen reflector bulb)

Safety and lighting

Electricity poses a great risk.By law the building must be fitted with a

safety switch.Electrical fittings should be regularlyinspected by a qualified electrician.

Staff and volunteers must be trained andfamiliar with the equipment.

PPE (Personal Protective Equipment).Safe work practices.

Safety and lighting

Recommended PPE(Personal Protective Equipment)

Quality rubber-soled shoesFibreglass ladder

GlovesEye protection

Safety and lighting

Safe work practices

Work from behind light fittings (avoidingshort-term dazzled effect and long-term eye

damage).Check heat of lamps before handling.

Avoid unnecessary handling.
