Ussr projection lamp

Description

Operating instructions for projection electric lamps with built-in reflector Lamps are designed for nodular (8 and 16 mm) film projectors, They have a built-in aluminium reflector and are manufactured in the following types: Voltage Nominal power in volts NeNe nominal technical conditions Lamp types in watts 16  90 CPS 371 455 TU K16-90 K21-150 21.5 150 CPS 371 456 TU K16-90-1 16 90 CPS 371 482 TU To obtain a large and uniform illumination of the cinema screen, the lamps are designed for operation in a forced mode, which explains  their short service life.  OBSERVE THE FOLLOWING CONDITIONS DURING OPERATION: a) insert the lamp only into the de-energized panel of the projector, b) turn on the lamp by gradually increasing the voltage to the above nominal value;  c) do not operate the lamp at a voltage higher than the nominal, since such operation reduces its service life, and operating at a voltage below the nominal increases its service life, but at the same time its light parameters decrease;  d) do not allow the lamp to be used without artificial cooling, problems in cooling may cause premature swelling of the bulb and lamp failure;  e) use the lamp only in an upright position with the base down;  e) do not bend the contact pins of the lamp when inserting it into the socket to avoid cracks in the glass and air leakage into the lamp, as this will damage the lamp;  g), protect the lamp during operation from sudden mechanical influences, as this can lead to its premature failure;  3) Do not open the projector lamp cover when the lamp is on;  i) keep the lamp bulb clean — before lighting the lamp, remove dust and other impurities from it, which will reduce the effective light output of the cinema projector and worsen the lamp's operation.  A type.  M3EVP.  Zach.  7
