|
DEFINITION
|
Ampere (A or Amp)
|
|
The unit of measure for electrical
current. Basic formula for finding Amp draw (Amps = watts ÷
volts)
|
|
Bulb
|
|
The part of
the lighting system that generates the output. A bulb consists of
the following parts; a glass tube to contain the filament(s) and the
gasses, the filament(s), the gasses, and the base. |
|
Dichroic
|
|
A glass reflector and bulb assembly
that allows heat to dissipate through the reflector and away from
the bulb thus increasing bulb life.
|
|
Driving Light
|
|
A lighting device mounted to provide
illumination forward of the vehicle and intended to supplement the
high beam of a standard headlamp system. It is not intended for
use alone or with the low beam of a standard headlamp system.
|
|
Dual
Lamp System |
|
A PIAA innovation that places two
types of auxiliary light systems into one housing, usually a driving
light and a fog light.
|
|
E-Mark |
|
Lamps and Bulbs that comply with
European vehicle lighting regulations
|
|
Filament |
|
A metallic coil inside the glass
tube of a bulb with enough resistance that when an adequate electrical
current flows through the coil, it glows and produces the light
output.
|
|
Fog Light
|
|
A lighting device providing illumination
forward of the vehicle that enhances visibility in fog, rain, snow,
or dust. Fog lights are intended to be used in conjunction with
standard headlamp low beams.
|
|
Guage
|
|
A standard designation of wire
sizes. The larger the guage number, the smaller the wire.
|
|
Glass Tube
|
|
The part of
the tube that encases the filament and the gasses in an airtight environment. |
|
High Intensity Discharge (HID)
|
|
A light source in which light is
produced by a stabilized arc that burns at a much higher color temperature
which creates a whiter light output than a standard halogen bulb.
This arc is generated with an igniting system and ballast.
|
|
Ion Crystal
|
|
A proprietary coating applied to
a bulb or lens that transforms the light output to amber with much
higher efficiency than conventional amber colored lenses.
|
LED |
|
Light
Emitting Diode. Solid state bulb using very low power and giving a
long life. |
|
Lens Fluting
|
|
A process in lamp design that molds
the lens to control the beam pattern by deflecting the light to
the desired point in the beam. Lens fluting usually looks like vertical
cuts in the lens.
|
|
Multi Surface Reflector
|
|
MSR, A reflector designed to control
the beam pattern with a computer designed surface to project the
light precisely to the desired point in the beam without the use
of fluting.
|
|
Pencil Beam
|
|
A narrow beam of light that has
a very long range with minimal side to side illumination.
|
|
Plasma Blue
|
|
A proprietary process applied to
a bulb or lens which transforms conventional halogen light output
to a bright blue-white color similar to the look of H.I.D. lamp
systems.
|
|
Projector Lens
|
|
An ellipse shaped lens that concentrates
a beam of light coming from a set back bulb and reflector. The beam
is usually controlled with a shield to give the beam a very sharp
cut off point. This makes a great fog light or headlight low beam.
|
|
Relay
|
|
An electromagnetic device that
opens or closes the flow of current in a circuit. Normally used
to reduce the amount of electricity through a switch.
|
|
Super White
|
|
A proprietary process applied to
a bulb or lens that transforms the light output to a brilliant white
that is closer to natural sun light than a standard bulb.
|
|
Wiring Harness |
|
A system that contains switch,
relay, fuse, and the correct gage wire for the intended application.
|
|
Xenon |
|
The gas used
in HID systems that produce the extreme white color. Xenon gas is
also used in some halogen bulbs to produce a whiter light and to keep
deposits off the glass tube. |
|
XTRA
|
|
A PIAA term used to designate high
efficiency bulbs that are designed to produce greater light output
than its rated power consumption. (Example 55watts = 85watts of
light output)
|
|

|
Notice to Customers
|
PIAA lamps are intended for use solely as auxiliary
lighting. PIAA lamps are not intended to be used for headlight
purposes, nor are they certified for headlight usage. Lighting
laws vary from country to country. PIAA E-Mark
Lamps and Bulbs comply with European vehicle lighting regulations,
however PIAA makes no representation or warranty, either expressed
or implied, as to the legality of its products for street use
on any vehicle or in any location. PIAA lamps are designed to
improve visibility during night time motoring and inclement weather
conditions. However, irresponsible use of any auxiliary light
can be dangerous and illegal.
