Knowledge of incandescent light bulbs

2016-12-26

Let’s first look at the structure of incandescent bulbs.
“PR” is the most common flashlight lamp bulb. They have a contact metal base with a metal ring, a glass cover and a glass capsule containing a filament. The light bulb is the metal ring is fixed on the light, so it will not shift at the time of the collision, but it is possible to break or break the bulb filament.
The double – needle bulb is a small glass capsule with a filament and two pins. This bulb is plugged into the socket and fixed on the socket. So in a long period of impact, this form of light bulb may fall off, then just gently put it back into the socket just fine. Because this bulb does not have that metal base, so they will be very small volume, take two spare no trouble. We can see this bulb in MiniMagLite and Streamlight Scorpion.
“Lamp Assembly” (bulb set) is usually the safest form. Usually one or two bulbs listed above will be permanently installed on a carrier. Some LampAssembly is just a carrier, some will also have multiple reflective bowl. This form is usually more expensive. Surefire is a complete light bulb set.
All the bulbs mentioned above may have different chemical compositions.
“Standard” bulbs have no filler outside the glass capsule, vacuum. Its benefits are either cheap or cheap, they emit the least light.
Krypton (krypton, rare gas) is the second common.
They are the most common in the cheap flashlight bulb in. This glass capsule bulb filled with krypton gas, krypton lamp can help produce more light.
Halogen (halogen: including fluorine, chlorine, bromine, iodine or astatine) lighting must be bright than the above two, it also needs more power. It is also more durable, the lamp bulb is filled with halogen mixed gas, these gases can protect the filament, but also help the filament to produce more light.
Xenon (xenon bulb, rare gas) filled with xenon, krypton and halogen, it can help extend the life of the filament and produce more light. Unlike others, xenon produces pure white light. You can buy the xenon lamp is probably in the best incandescent bulb flashlight.
HID (High IntensityDischarge, high intensity discharge) bulb is to heat the gas by generating an instantaneous discharge between two points. This light is very bright, usually in luxury sedan headlights (white lights) and military lights to see. By the way, if you see the lights of some lights are very blue, or with blue green, then they are just in front of the ordinary car with a layer of film, to install other people’s high price lights, what mentality.
