Description
Technical field
The present invention relates to light of stage technical field, and cooling gas flow control system is carried more particularly, to one kind
Stage lighting.
Background technology
In light of stage field, the temperature of the conventional light source such as high-tension electricity arc lamp center luminous point when work is very
Height（8000 degree or so）, it is just the high temperature that the surface temperature of the relatively low luminescent ball of temperature has nearly thousand degree.In such high temperature
Under the conditions of, bigger heat can be produced, if heat is discharged not in time, lamp interior flow field can be caused uneven, in light source
Portion's stress is excessive, and the air near luminescent ball can produce violent expansion so as to cause the drastically change of pressure, and due to gravity
This stress of relation and the change of pressure be anisotropic, and then cause bulb to light the energy density distribution pole of ball surface
Spend uneven so that bulb luminescent ball（Glass material）Produce violent stress variation and irreversible damage occurs, be such as broken,
Blast etc., so as to cause the fried bubble of light source, turn white (light transmission rate decline) cause light efficiency the consequence such as drastically to decline；Therefore, typically all
Corresponding thermal system can be equipped with to carry out cooling to light source.
And according to the demand of stage effect, it is desirable to which the rising angle of optical device is that any angle in 360 degree is real at random
When it is controllable, at any time coordinate stage the story of a play or opera change provides a variety of sound state light efficiencies, give the gorgeous brilliant sense organ of spectators
Effect, therefore stage lighting（Such as Adjustable head lamp）The dimensional orientation of its internal light source is real-time change when in use, at present, existing
The working condition of thermal system and control are substantially changeless preparatory condition, and thermal system can not be according to the position of stage lighting
Put change to be adjusted, the gas flowfield of the light source of control cooling in real time, this will make light source produce local excessive cooling or cooling
Deficiency, it is impossible to effectively meet radiating needs, influence the security of light source, reliability and service life, this gives the heat of stage lamp
Learn design and bring huge problem.
The content of the invention
The present invention is to overcome at least one defect described in above-mentioned prior art, there is provided one kind carries cooling gas flow control
The stage lighting of system processed.The present invention is simple in construction, easy to use, can improve security, the stability of light fixture, extends light of stage
The service life in source.
