or fixtures are electric receivers that convert electrical energy into another
light. From a technical point of view, we distinguish between two objects and
is called lamp supported device, which produces light, also called bulb or
focus, being the luminaire utensil or appliance that serves soporte.
According
to this latter definition, the luminaire is responsible for control and
distribution of the light emitted by the lamp. It is therefore important that
the design of the optical system the shape and distribution of light care, the
performance of the whole lamp-light and the glare that can result in users.
Other requirements for luminaires is that they are easy to install and maintain.
To do this, the materials used in its construction must be adequate to
withstand the environment in which the luminaire has to work and maintain the
temperature of the lamp within the operating limits. In addition, the lamps
that run on electricity, must submit a number of features for the safety of
users against electrical contacts. All this without losing sight no less
important aspects such as economics or aesthetics.
antique
lamps [edit]
Before
the invention of the electric light, the lamps were vessels containing an oily
liquid, which was burned by a wick. The discovery of the wick, submerged
fiber-fat combustible material is lost in the darkness of time (it is already
used in the upper neolithic). With this discovery comes the primitive lamp, which
was reduced to a stone bowl with a groove for the wick made of moss and a
handle for hand away from the flame. Of these lamps they have been found
several copies of the Neolithic. These stone lamps continue to be used by some
primitive peoples such as the Eskimos of Alaska Aleuts, using whale oil as
fuel.

drilling a floating material (cork) to keep it upright.
