Lamps and lighting

Lamps and lighting are an
essential element in modern living. 
Both for practical purposes and for aesthetic reasons, it is ensured
that the light is provided in practically all spaces used by humans in 21^st
century.

Artificial light and
natural light

A certain space can
be illuminated by either artificial light or natural light.  Artificial luminaires are like lamps with
lamps and other luminaires are a ubiquitous function in modern life.  Natural daylight can be captured to give
light to a space using windows and skylights. 
This is the oldest way to illuminate the interior of a living
room.  Daylight reduces electricity
consumption and has been shown to have positive effects on the inhabitants of
space.  For example, patients in
hospitals and students in schools have been found to be in a better state of
mind when there was enough daylight in their living
spaces.

Types of
lamps

First and foremost, there
are compact fluorescent lamps that can take the place of light bulbs in new
and existing installations.  LEDs or light
emitting diodes are another type that are solid state devices that emit light
through electron motion in a semiconductor material.  LED lights are often claimed to be the best
and most environmentally friendly light source.  Neon lights emit light in colors depending
on the gas contained in a glass tube. 
Halogen lamps are incandescent lamps that contain halogen gases such
as iodine or bromide inside.  This
makes it more efficient than a regular light bulb.  Fluorescent light is a tube coated with
phosphorus and contains mercury vapor under low pressure.  This emits white
light.

Use of lamps and
lighting

The use of lamps and
lighting is quite obvious.  We need
light for practical purposes.  However,
there are other uses that are less obvious. 
Having correct and strategic lighting improves the appearance of a
certain space.  Living and working in a
well-lit environment also improves performance.  It also affects their mental state in a
positive way.  In a study conducted in
the 1970s and 1980s, it was found that patients who underwent surgery would
have shortened postoperative hospital stays if they had been allocated rooms
with a view of natural greenery compared to the patients who lived in rooms
with windows against a brick wall. 
They also took less painkillers than the latter group.
