Among the artificial lighting sources, incandescent
bulbs are the most massive bulbs. Wherever there is an electric current, can
detect the transformation of its energy into light, and is almost always used
for this purpose incandescent lamps. We will understand how and what glows in
them, and what they are.
According to their function, incandescent
lamps’ general purposes are most common (LON). All LON produced must meet the
requirements of GOST 2239-79. They are used for exterior and interior, as well
as for decorative lighting (e.g. 60W E27 bulb), domestic and industrial networks with a voltage of 127 V and
220 V, 50 Hz.
BOSOMS have a relatively short period of
time, an average of 1,000 hours and low efficiency - they are converted into
light only 5% of the electricity, and the rest is released as heat. A feature
of low power (25 W) LON is used therein as a filament, a thread coal.
Spot lights bulbs differ significantly
larger than the other types, capacity and are designed for accent lighting or
filing of light signals over long distances. According to state standards are
divided into three groups: the film projecting lamps (GOST 4019-74), for
general purpose (GOST 7874-76) and lighthouse lamps (GOST 16301-80). Incandescent
body in floodlight lamps longer and thus arranged more compact to enhance the
overall brightness and further focusing the light flux.
Mirror incandescent bulb is distinguished
by a special design and a reflective aluminum layer. The light guide portion of
the bulb is made of frosted glass, which makes the light soft and smooth out
the contrasting shadows of objects.
BTW, you can select the wholesale Edison bulbs at Banggood with high quality and reasonable prices.
