| Title: |
Method and Apparatus for Controlling the Temperature of a Multiparameter Light |
| Abstract: |
A multi-parameter light is a type of theater light that includes a lamp in
combination with one or more optical components such as reflectors,
lenses, filters, iris diaphragms, shutters, and so forth for creating
special lighting effects, various electrical and mechanical components
such as motors and other types of actuators, wheels, gears, belts, lever
arms, and so forth for operating the optical components, suitable
electronics for controlling the parameters of the multi-parameter light,
and suitable power supplies for the lamp, motors, and electronics.
Typically, the lamp is enclosed by the lamp housing, which also contains
the other optical components and many of the electrical and mechanical
components which operate them. As the lamp and the various components
within the lamp housing generate a great deal of heat and as various
environmental conditions such as ambient air temperature and humidity can
affect the amount of heat dissipated by whatever cooling technique is used
in the multi-parameter light, the temperature within the lamp housing is
managed by controlling the amount of power furnished to the lamp in
accordance with the temperature sensed by one or more thermal sensor(s)
positioned in appropriate location(s) preferably inside the lamp housing
or on one or more of the cooling system components. As the sensed
temperature deviates from a desired temperature specification, the output
of the power supply for the lamp is adjusted so that the heat generated by
the lamp is modified in such a way as to bring the sensed temperature back
into specification.
