Quantitatively Reliability

cat December 9th, 2013 by Virtual Keeper

Accordingly, when evaluating the performance of lamps are the most important: energy efficiency lamps in a given region of the spectrum efficiency efficient lamps for the corresponding effective radiation detector output lamp radiation effective flow, as measured by the level of response receiver – dimensional value, measured in special units, chosen to evaluate the response of the receiver; kmax (h)-value of the maximum spectral sensitivity of the detector (dimensionless quantity). The work of the light source in any real lighting Installation is associated with a number of devices that provide normal operation of the source, the radiation source in redistributing the space for the best performance of the receiver and the system realizing the energy receiver. In all these devices tend to have the energy loss. So depending on what part of the flux or effective flow to a part-consumed power is, it is possible to obtain different efficiency characterize the transformation of the energy of a device of lighting installation. Reliability – ability of an object to perform all specified functions under certain operating conditions within a specified time at conservation values of key parameters in a pre-established limits. Reliability – a complex property, which consists of a combination of properties: reliability, durability, maintainability, safety.

Quantitatively Reliability is measured by a number of indicators (for more details – see GOST 27.002-83). For sources of optical radiation the most important indicators of reliability are the types of tenure. Full term of service, or duration of burning lamps is the total burning time of commencement of operation or testing of hours until the total loss of efficiency, such as incandescent lamps because of burnout thread in discharge tubes due to loss of ability to light up, etc. The useful life of lamps is the total burning time of lamps in hours from the start of operation or testing prior to the departure of one of the parameters that determine the appropriateness of the use of lamps of this type, the specified limits, for example due to reduced flow or brightness below a certain limit for lighting lamps and irradiation or inability to use special discharge lamps of high-brightness light-optical devices in due to the instability of the arc, etc.
