A kind of stage lighting radiator structure
Technical field
The present invention relates to theatrical luminaire field, be specifically related to a kind of stage lighting radiator structure.
Background technology
In light of stage technical field, in stage lamp use procedure, the more satisfactory state of its light source (as bulb) is, the top of bulb and bottom (being namely positioned at the lamp socket end outside bottom reflector) temperature relatively low, and bulb foam temperature is relatively high, meeting under these conditions required, just obtaining extraordinary lighting effects, the service life of bulb and other assemblies can be ensured again simultaneously.
But light source is the interior parts producing maximum heat of stage lamp often.Particularly high-power stage lighting, the too much heat produced due to the bulb foam of high temperature can conduct to its bulb top and bottom, if can not leave fully in time, the top of bulb and the temperature of bottom can rise very high, not only affect lighting effects, and seriously reducing the life and reliability of the assemblies such as bulb, circuit, insulating materials, this just needs to cool light source two ends or dispel the heat.
Especially for single-end discharge lamp bubble light source, because its top comprises the electric conductor with Electrode connection, in the event of high temperatures, described electric conductor easily oxidized and corrosion on the one hand, is peeling stress because described electric conductor is different from the thermal coefficient of expansion of encapsulating material on the other hand.The temperature on the top of Gu Danduanfang electricity Deng Pao is unsuitable too high.In addition, in order to reduce the heat that projecting beam middle infrared (Mid-IR) produces, the light source of stage lamp generally employ dichroic reflector and light beam heat-protecting glass, and the temperature of reflector inside can raise further, is thus necessary very much to carry out sufficient Local cooling to the top of light source.
Although there is various light sources heat abstractor in prior art, but these heat abstractors generally all carry out reflector outside (light source is arranged in reflector), as, in reflector openend, upper outer arranges air-supply conduit, by air-supply conduit, the cooling blast in the external world is directed to the upper outer of reflector, and then carries out cooling to light source air-supply; Or, by arranging radiator to dispel the heat around reflector outer wall.
Although above-mentioned cooling mode meets the overall heat rejection requirements of light source reluctantly, but still there is following defect: (1) due to wind-force directionality inadequate, easily cold wind band to bulb foam, bulb foam temperature is reduced, cause the Duo gas circulations such as bulb foam halogen tungsten abundant not, thus make the crystallization be adsorbed on foam inwall on colder foam of the Duo gases such as halogen tungsten, inwall is caused to occur black crystalline, black easily absorbs heat and light transmittance is reduced greatly, thus have a strong impact on lighting effects, even can affect bulb service life; (2) due to wind-force directionality not and concentrated not, cause bulb tip temperature too high, there is crystalloid oxide in exposed metal position, bulb top, come off from level to level, cause after overheated, overcurrent and disconnect or cause fried bubble phenomenon, and make its bulb and bulb peripheral components occur damaging phenomenon.
At present, the mode of stage lighting air duct radiation, the overwhelming majority adopts bulb air and outside air convection mode to dispel the heat, although the cooling requirements that bulb is basic can be met, but under atrocious weather or under the environment having a long-time instructions for use, because heat radiation does not reach requirement, the lost of life of bulb still can be caused even to damage.
Summary of the invention
Goal of the invention of the present invention is the defect overcoming prior art, provides a kind of stage lighting multi-radiating structure.

Detailed description of the invention
Structure and working principle of the present invention is described in detail below in conjunction with accompanying drawing.
With reference to shown in Fig. 1, the utility model provides a kind of stage lighting radiator structure, this structure comprises heat sink assembly and fixed mount assembly, stage lamp includes bulb 3, and bulb 3 and heat sink assembly are arranged on m, and bulb 3 is provided with electric power-feeding structure, bulb installation structure etc., bulb 3 is for providing light source, heat sink assembly provides cooling effect for bulb 3, and particularly, described radiator structure is that bulb 3 is lowered the temperature by the mode of the heat accelerated air flowing and take away in fixed space.
With reference to shown in Fig. 1,3, wherein, m includes fixed mount 4, two pieces of bed type supports 42 that fixed mount 4 comprises fixed disk 40 and is connected with fixed disk 40, after having assembled, support 4 is roughly U-shaped structure, fixed disk 40 is provided with the first through hole 41, when bulb 3 is connected with support 4, the luminous component on bulb 3 is through through hole 41, and the luminous component namely on bulb is positioned at the top of fixed disk 40.
