THE BULB BLOG

Not everyone is aware of the science behind projector lamps. Though it is not mandatory to know about projector technology, it would help us to have a better understanding on how these projector bulbs work.

Technically, projector lamps are called high intensity discharge lamps because they produce light from a very small electrical discharge. Hence, they use less energy to give brighter light. It is very advantageous to use such projector lamps because they not only help conserve energy, but also work for a long period of time.

The lighting technology in projector bulbs is similar to the process by which lightning is produced in an electric storm. Nitrogen atoms present in the air glow as a result of the high voltage discharge created during an electric storm. This can be compared to the working of a projector lamp. Metal halide atoms present in the projector lamp glow due to the electrical discharge that is produced from the projector’s power source.

Mercury halide gas is used in projector lamps as it has a high vapor pressure. Halides are also used because they vaporize easily avoiding corrosion of the projector bulb.

Scientists discovered that when a metal is introduced to a naked flame, it glows. This basic concept of using metals to create high intensity light was applied to projector lamps. An electrical discharge is produced between the two electrodes used in the projector bulb. This discharge excites mercury atoms to produce light.

Though, these lamps may be costly at first, they are cost effective in the long run. If you are planning to buy projector lamps at affordable costs, BulbToGo is the perfect place to go to.
