The ancient Greeks already knew of optic telegraphy with mirrors and torches, which was rediscovered in the Renaissance and eventually led to Samuel Morse’s eponymous Code. Morse lamps are still used to this day at sea for short distances. And modern glass fibre networks, without which the internet and fast computer networks would not be possible, are the youngest children of optical telegraphy.
Light and motion
As long ago as 300 BC, large light fires were burning to show ships the way: the Pharos of Alexandria and also the Colossus of Rhodes. Light fires and lighthouses for seafaring remained the same for many centuries.
At the beginning of the 19th century, the railway and the steamship heralded the beginning of modern travel. After a very short time, lighting and the equipping of transport vehicles and roads with lighting and light signals became an absolute necessity.
Light and safety
Not only in traffic are light signals indispensable now. At the beginning of the 20th century the first lighted call systems, as they are still to be found today as call buttons in hospitals, were already in use.
And who would care to do without emergency lighting, anti-panic lighting or safety lighting for escape routes in an emergency these days?
