How does a Lumen (Lux) Meter work?
To begin with a light meter is used to measure the amount of light distributed over a particular area at a specified distance from the light source.
The units that a light meter will measures in are either Lux, lumens and/or foot candle.
Therefore the amount of light will vary between light sources such as a well-lit office.
Having a reading of 500 Lux to an overcast sky of 5000 Lux.
To measure the light intensity, light meters use a sensor called a photodiode.
Also a photodiode is a semiconductor that converts the incoming light to electrical current.
The sensor conducts electrical current directly proportional to the amount of light that it measures.
Filters and built in lenses make up the photodiode.
A photodiode will also differ in surface.
There are many applications to use a light meter to measure light intensity.
Office lighting is an important part of occupational health and safety.
Proper lighting can reduce eye fatigue and headaches for people that work in an office for long periods.
Proper lighting will also prevent workplace accidents by increasing the visibilities of dangers and reducing momentary blindness.
Councils will use a light meter to check if street lights are performing at optimal levels during night time.
A light meter will ensure street lights are emitting the right light levels to improve road and pedestrian safety.
Therefore it will also help councils to reduce energy bills by ensuring the street lights aren’t producing too much light.
Optimizing light levels in museums and art galleries is very important.
The optical light levels will ensure the intricate details and colour work of a piece of artwork won’t be missed by the viewer.
Also it ensures the artwork is properly displayed as intended.
The wrong light intensity can potentially harm light sensitivity artworks.
Lastly measuring the light intensity ensures the preservation of light sensitive artworks.
