How to choose a lamp for a projector
In the operation of the projector, an important elementis a lamp. It is on it that the whole load is necessary, therefore, a lamp is often replaced. Currently, the projector lamps differ in size and power. It is necessary to know what light bulb to buy for the projector. Often a breakdown of equipment may well be a too powerful light bulb. Undoubtedly, the brightness and quality depend on the lamp's work. Lamp for the projector has a special property - do not burn instantly, but fade out, although the process of extinction can continue indefinitely.
As a rule, most projectors are set to2 modes - this is forced with increase, where the functionality of the lamp is reduced by half and optimal with a sufficiently long lamp life. As a result, the forced mode is considered standard, and the optimal mode is an economical mode.
In projectors that have a conventional hard cut-off,the need to change the lamp appears after 1000 hours of operation in the standard mode and in the economic mode after 2000 hours. In projectors that are set to a smooth turn-off, the terms are correspondingly doubled. Projection lamps, as a rule, are gas discharge - this is an electric discharge similar to the lightning discharge, is formed in a gaseous medium as a source of light. Modern version is metal halide lamps for projectors, which are characterized by sufficient efficiency and maximum service life. Such lamps contain mercury vapor, which significantly increase the power of light and increase the return of light. Their luminescence is uniform and intensive and the cost is quite low, which is in great demand in office and home multimedia projects. Quite often, lamps of this type are supplied by manufacturers with filters, which make the image more real and clear. Today you can in any online store at a fairly attractive price.
An excellent option in professional projectorsFor cinemas and large enough halls are considered xenon lamps, which produce super-bright projections of large sizes. The principle of operation of these lamps is slightly similar to the metal halide, but instead of mercury vapor, xenon gas is used under pressure. This type of lamps for projectors have the correct color distribution and high luminous efficiency. A huge advantage of these types of lamps is a quick warm-up, after which the best picture is shown.
