Description
Technical field
The utility model relates to the stage illumination, lighting field of light fittings, particularly a kind of stage lamp of good heat dissipation effect.
Background technology
In the light of stage technical field, in the stage lamp use procedure, the more satisfactory state of its light source (such as bulb) is, the top of bulb and bottom (namely being positioned at the outer lamp socket end in reflector bottom) temperature is relatively low, and bulb foam temperature is relatively high, satisfying under the condition of these requirements, just obtain extraordinary lighting effects, can guarantee again the service life of bulb and other assemblies simultaneously.
But light source is the interior parts that produce maximum heats of stage lamp often.High-power stage lighting particularly, because the too much heat that the bulb foam of high temperature produces can conduct to its bulb top and bottom, if can not in time leave fully, the top of bulb and the temperature of bottom can rise very highly, not only affect lighting effects, and seriously having reduced the life and reliability of the assemblies such as bulb, circuit, insulating materials, this just need to cool off or dispel the heat the light source two ends.
Especially for single-end discharge lamp bubble light source, because its top comprises the electric conductor that is connected with electrode, in the situation of high temperature, on the one hand easily oxidized and corrosion of described electric conductor produces peel stress on the other hand owing to described electric conductor is different from the thermal coefficient of expansion of encapsulating material.The temperature on the top of Gu Danduanfangdiandengpao is unsuitable too high.In addition, the heat that produces in order to reduce the projecting beam middle infrared (Mid-IR), the light source of stage lamp has adopted dichroic reflector and light beam heat-protecting glass usually, and the temperature of reflector inside can further raise, thereby is necessary very much sufficient Local cooling is carried out on the top of light source.
Although there has been the various light sources heat abstractor in prior art, but these heat abstractors generally all carry out at reflector outside (light source is arranged in the reflector), as, outer setting air-supply conduit above the reflector openend, by the air-supply conduit that the top that the cooling blast in the external world is directed to reflector is outside, and then carry out cooling to the light source air-supply; Perhaps, dispel the heat by around the reflector outer wall radiator being set.
Although above-mentioned cooling mode satisfies the overall heat radiation requirement of light source reluctantly, but still have following defective: (1) is because heat abstractor (such as the air-supply conduit) is arranged on the reflector outside, far away apart from light source, cooling blast just arrives the bulb top after long distance, therefore, the directionality of wind-force not and concentrated not so that the cooling wind-force that arrives after the bulb top is less, can not to satisfy effectively cooling requirement; (2) because the wind-force directionality is inadequate, easily the cold wind band to the bulb foam, so that bulb foam temperature reduces, cause the Duo gas circulation such as bulb foam halogen tungsten abundant not, thereby make the crystallization and be adsorbed on the foam inwall on colder foam of the Duo gases such as halogen tungsten, cause inwall the black crystallization to occur, black absorbs heat easily and light transmittance is reduced greatly, thereby have a strong impact on lighting effects, even can affect bulb service life; (3) since the directionality of wind-force not and concentrated not, cause the bulb tip temperature too high, the crystalloid oxide appears in exposed metal position, bulb top, come off from level to level, cause behind overheated, the overcurrent to disconnect or cause fried bubble phenomenon, and so that phenomenon appears damaging in its bulb and bulb peripheral components.
The utility model content
Goal of the invention of the present utility model is to provide that a kind of wind-force directionality is good, the stage lamp of good heat dissipation effect.
For achieving the above object, the utility model adopts following technical scheme, a kind of stage lamp of good heat dissipation effect, comprise the light source that is arranged in the light fixture, reflector and radiator, wherein light source is arranged in the reflector, radiator is arranged on periphery and the bottom of reflector, also comprise the thermostable transparent guide duct, one end of described thermostable transparent guide duct is connected with stage lamp inner blower system, the other end extends to reflector inside by the opening part on the reflector sidewall, and the mouth of pipe carries out Local cooling towards the light source top to the light source top, has the cooling wind-force of relatively concentrating, can greatly improve its cooling effect and radiating efficiency, effectively guarantee the service life of light source and other assemblies of stage lamp, and so that stage lamp be not easy to break down, reduce simultaneously the air use amount, reduce the energy consumption of stage lamp.
The utility model further improves and is that described thermostable transparent guide duct is quartz glass tube, and the quartz glass tube high-temperature resistant result is good, does not stop again light simultaneously.
The utility model further improves and is the center extended line of described thermostable transparent guide duct and the center line oblique of light source.
The utility model further improves and is that described light source is the single-end discharge lamp bulb.
The utility model further improves and is that described thermostable transparent guide duct is two.
The utility model further improves and is, this stage lamp also comprises the bottom coohng guide duct, one end of this bottom coohng guide duct is connected with stage lamp inner blower system, the other end passes the place, side, bottom that radiator extends to light source, its mouth of pipe carries out cooling towards the light source bottom to the light source bottom.
The beneficial effects of the utility model:
(1) the utility model is by setting up the thermostable transparent guide duct, in reflector inside Local cooling is carried out on the light source top, has the cooling wind-force of relatively concentrating, its cooling effect and radiating efficiency can have greatly been improved, effectively guarantee the service life of light source and other assemblies of stage lamp, and so that stage lamp be not easy to break down.
Therefore (2) because the thermostable transparent guide duct is nearer apart from light source position, have reasonable directionality, be difficult for the cold wind band can effectively guaranteeing the suitable temperature of foam to bulb foam place, guarantee that light source is normally luminous.
(3) set up the bottom coohng guide duct in the reflector bottom, can greatly improve cooling effect and the radiating efficiency of light source bottom, so that the light source bottom keeps lower temperature.
