Incandescent lamps are the most common
source of light for residential use. For over a hundred years ago, the industry
has mastered the production of such lamps. However, the global problem of
energy conservation has called into question the use of incandescent lamps
because of their high power consumption. Part of this power is simply a
"warm air", which is a disadvantage of lamps of this type.
European countries have almost completely
abandoned the production of incandescent light bulbs in favor of energy-saving
lamps. However, in the former USSR, incandescent lamps are widely used due to
its low cost and resistance to voltage change. In addition incandescent lamps
do not contain any toxic substances and do not require special measures for
their disposal. In the first place must pay attention to the size and shape of
the bulb, and the terminal units. Modern lamps are available at a sufficiently
compact lamp.
Dimensions are standardized lamp base. The
most commonly used bulbs with E27 base, E14, E12 (e.g. E12 220V light bulb) and E10. Digital signage determines the diameter of
the thread of the cap in millimeters. The letter "E" indicates that
this is a threaded socket (Edison Screw). Also lamps distinguish the types of
pads. Type "A" has the smallest area of contact, the type
"C" – highest. Note the method of connecting the outer contact member
with the cap. Spot welding (type "B") and solder (type "A"
and "C") is most commonly used.
When choosing an incandescent lamp, it is
necessary to pay attention to the way the bulb attachment to the cap, and
fixing the filament. To connect to a glass flask with a metal cap used special
postmark. In this connection it is easily visible through the flask. Poor
fixation filament leads to an increase in the transition resistance at the
point of contact and "burn" lamps. BTW, you can select the quality bulbs
(e.g. LED B22 candle) at Banggood for high quality and reasonable prices.
