Abstract
The present invention relates to a light diffuser, especially for decorative lightening, comprising refractive and/or reflective planes which, in macroscopic terms, were chaotically or quasi chaotically formed. The light diffuser can be made either of a flexibe envelope filled with a liquid or a flexible material having an outside surface which, in macroscopic terms, has been chaotically or quasi chaotically formed.
Description
The present invention relates to a kind of light diffuser that is mainly used in the decorative lighting purpose.
The known light diffuser that shape of all kinds is arranged.Be, or for example on wall and so on, to cause the pattern of noticeable as far as possible light for what decorative lighting be worth to be pursued at light diffuser itself or at reflecting surface by refraction and/or reflecting effect.For this reason, traditional light diffuser comprises reflector, optical conductor or the solid that is used to make needed reflection or refraction effect mostly.
These solids are made by glass, pottery, plastics or surface treated metal mostly, and well-regulated geometry or the irregular structure of microcosmic, for example shape of regular prism body.
If mainly should cause reflecting effect, this solid or then all with a kind of material manufacturing that can suitably reflect, or use this material coating.
Once attempted in addition by the use rough surface or by adopting the solid shell that fills the glass that grinds to cause the effect of noticeable light.For causing refraction effect, these solids must be made with material transparent certainly.
Yet, adopt the known light diffuser of this class,, can not or can not reach the purpose that causes noticeable as far as possible light effect with satisfactory way.
The present invention is a starting point with this prior art, and its purpose is for creating a kind of light diffuser that is mainly used in the decorative lighting purpose, obtains the effect of noticeable light by means of its available simple method.
The present invention reaches this purpose by means of the feature of claim 1.
By irregular or accurate irregular refraction of macroscopic view and/or reflecting surface are set, formed desired noticeable illuminating effect.Term " macroscopic view irregular (makroskopisch chaotisch) " is used in the application's scope and known irregular (mikroskopisch unregelmabig) structure example of microcosmic such as rough surface or the very little glass contrast of irregularly shaped object as grinding.Term " accurate irregular (quasi-chaotisch), refer to the irregular structure of a kind of outward appearance, even it may have certain regularity, but the observer does not see this regularity.
By a kind of form of implementation of the present invention, light diffuser is made of the transparent outer cover of a filled liquid clear medium, and it is irregular or accurate irregular that it is configured as macroscopic view, that is to say corresponding irregular outer surface.Even also available lower expense was made when its size of this type of light diffuser was big.
The advantage that adopts soft shell to bring is, they for example can be contained in the outer rigid housing when a plurality of this type of light diffusers combination, and owing to has elasticity " engagement " and adapt to the shell inner cavity of arbitrary shape better easily mutually.Provide compact structure thus, these structures can cause noticeable optical effect equally.Flexible light diffuser can also or be out of shape between the light period in the light transmission, and thereby generation corresponding effects.
According to a kind of form of implementation of the present invention, shell is with a kind of fexible film manufacturing, in this case, shell for example just not exclusively fills with liquid medium, and before shell is closed hermetically, from the residual volume of shell, remove air (for example by suction or pressurize) to small part, thereby can cause the irregular deformation of shell.
In the another kind of form of implementation of the present invention, shell causes by means of a kind of mechanism in the distortion that it fills and sealing is front or rear.For example at heating additionally and meanwhile folding, warpage or crumple under the situation of shell, can cause needed distortion.
In order to make shell keep the best irregular shape of this expectation, the thickness of shell or sheathing material should be chosen as, although owing to filled liquid produces interior pressure, but still can keep its shape invariance.In order to stablize this shape, shell can also coat a kind of material transparent, for example goes up transparent polymer by cast.
Shell with thin film fabrication can be made by welding two or more preferably flat thin-film member.For example, film two-layer or that multilayer is stacked entirely welds mutually in edge, makes filled a mouthful of being used for liquid medium open wide in this case at least.After filling and seal this filled mouth, the mechanically distortion of the bag of the multilayer of so making in case of necessity is so that obtain a kind of the have desired refraction or the member of reflecting effect in this way when illumination is penetrated.
By another embodiment of the invention, the shell that is designed to fexible film also can be made by blown film.Utilize a mould in this case mostly, plastic gas bag is blown into by causing to press in sufficiently high in mould.The advantage of comparing this method with welding plural layers spare is that shell has virtually no the seam that can see from the outside.
Shell for example also can be made with tubular film, and a flexible tube section is always closed hermetically in the end in this case.
By another kind of form of implementation of the present invention, portion is provided with and can be out of shape the best film that has been crumpled arbitrarily in the enclosure.This film is designed to transparent mostly, but can certainly make with reflecting material.But, if should cause noticeable illuminating effect, then must adopt a kind of like this transparent membrane, promptly its refractive index should be different with the liquid refractive index in being in shell.Because refraction effect just just produces when a kind of medium with first kind of refractive index carries out the transition to the medium that another kind has the second kind refractive index different with first kind of refractive index at light.Certainly,, (part) reflection also can take place in this transition.
Also can make with a solid of being made up of one or more flexible materials by light diffuser of the present invention, it is irregular or accurate irregular that its outer surface is designed to macroscopic view.Be applicable to this for example elastomeric silicone, it still keeps flexibly flexible in temperature from-50 ℃ to+200 ℃.This class A of geometric unitA can be made easily by cast or pressure injection.Wherein, material can be processed into intermediary, and it formalizes again behind partially hardened.Because the flexibility of this type of light diffuser is so still have the cited various advantages in front.
By another kind of form of implementation of the present invention, shell has smooth basically outer surface, and desired noticeable refraction and/or reflecting effect reach by means of the member that is located at enclosure.Here they can relate to and a kind ofly can be out of shape the best film that is crumpled arbitrarily, and/or can relate to the one or more light diffusers according to one of above-mentioned various forms of implementation of the present invention.
If be provided with some other light diffuser with any distortion shell in smooth basically enclosure, then this shell also can fill liquid medium.In this case advantageously, these other light diffusers fill liquid medium, and their refractive index is different with the refractive index of the liquid medium that centers on these other light diffusers.The refraction effect that is obtained in this way, more stronger than the refraction effect under the refractive index of the sheathing material only situation different with the refractive index of liquid medium.Certainly these equally also are applicable to the refractive index of solid.
By in this form of implementation of the present invention, outside shell is with a kind of material manufacturing of rigidity basically.Can obtain in this way under the extraneous mechanical influence and be located at the advantage that enough stability is arranged under its inner member or the liquid internal pressure effect.
In order to strengthen illuminating effect, can establish the other film that can be out of shape arbitrarily on the shell externally.It still can be designed to transparent or partial reflection at least.
In each illustrated in the above form of implementation, portion establishes other solids transparent or reflection in the enclosure, and these solids are in the suspension poised state in liquid.
Light diffuser also can be made by making up a plurality of light diffusers by above-mentioned form of implementation these one or more.Such one group of knockdown light diffuser can be for example by means of bonding or other connected modes one by one light diffuser couple together and make.
Can be made into the light diffuser of complete different patterns in this way by one or more basic modules.
By light diffuser of the present invention, maybe can be designed to it only by a for example light transmission of high power light source of light source that is arranged in the light diffuser outside, portion is provided with initiatively or this mode of passive type light source but also can be designed in the enclosure.Under the situation that an active light source is arranged, it for example can be a low pressure halogen bulb, and relates to fibre-optic end in that the situation of passive type light source is next.
For a kind of active light source, also can relate to a kind of high-power bulb, for example the high-voltage gas discharging light bubble.
Be combined in a kind of light diffuser of space structure by a plurality of single light diffusers, this class light source can certainly be arranged in the inside of this space structure, but is not in liquid medium, but is arranged between the shell of each light diffuser outside.
If active light source is positioned at the enclosure of a filled liquid medium, then this liquid can be used as cooling agent simultaneously, has therefore solved for the first time the special so far heat dissipation problem that never solves satisfactorily under the situation of high-power bulb.In this case, come from safe reason, this liquid medium should have nonconducting characteristic.
By dependent claims other forms of implementation of the present invention as can be known.
Further specify the present invention by means of the embodiment that represents in the accompanying drawing below.Expression in the accompanying drawings:
Fig. 1 has the flexible shell that can be out of shape arbitrarily by first kind of form of implementation of light diffuser of the present invention;
Fig. 2 presses the another kind of form of implementation of Fig. 1, has the additional film that can be out of shape arbitrarily that is provided with of portion in the enclosure;
Second kind of form of implementation of Fig. 3 light diffuser has the shell of geometrical figuration and the film that can be out of shape arbitrarily in the enclosure; And
Fig. 4 has the shell and the some other light diffuser that is located in the shell of the geometrical figuration of rigidity by the third form of implementation of light diffuser of the present invention.
The light diffuser of representing among Fig. 11 is made of the soft shell 3 of a sealing, and it is filled with liquid medium 5, for example water.The shell 3 of sealing has a kind of very irregular shape.
This type of light diffuser can for example be made by blown film, the transparent material that adds thermal flexibility in this case, as PVC, polyethylene or polypropylene, and insert in the blow mold and the inwall of wall by causing enough internal pressures to expand into to make this air bag and mould is in the degree of contact condition with suitable shape.After cooling, just can from mould, take out this thin and selected appropriate material to have flexible product owing to wall thickness.Then, shell 3 can completely or partially fill liquid medium 5 and the filled mouth of sealing.
The very irregular profile of light diffuser 1 also can be made with such method, promptly, at first make a more or less shell of rule by welding a plurality of thin-film member, its just part fill liquid medium 5, then take in the enclosure residual gas (air) away to small part.Shell 3 folds under suction function or wrinkle Zhe becomes irregularly shaped.The still closed hermetically mouth that fills after taking residual gas away to small part.Can certainly substitute and thisly take the way of residual gas away and residual gas is got rid of, for example the shell that fills by extruding part with any one method.
When being used as the material of soft shell and liquid filling medium, selection should note the requirement of sealing.For example, common film such as PVC, PE, PP or nylon are not suitable for being used for water-filling on the market, because they do not have enough water-tight property and air impermeability.Enough here sealings can be by obtaining at film surface handicapping interlayer, for example by applying alkyl silicon tetrachloride mixture.
The for example various types of oil of macromolecular material are applicable to that also as liquid filling medium, their molecular dimension is greater than the pore-size of film.No longer need barrier layer in this case.
Light diffuser causes mechanical damage around can additionally preventing by means of more stable protective sleeve (not shown).This for example can pour into a mould transparent polymer and make on shell 3.Preferably adopt some materials so in this case, even promptly they still keep enough flexibilities after sclerosis.
Light diffuser represented among Fig. 1 also can be made of same shape a kind of solid of best flexible material system.For example elastomeric silicone is applicable to this, and it still keeps elasticity in temperature from-50 ℃ to+200 ℃.In addition, because its good chemical stability, they can use in the process of photoreaction; Glass then is not suitable in the photoreaction process of for example photic sour this meeting etching glass that dissociates.
This uncanned light diffuser can still can formalize after cast or pressure injection in this case by means of the suitable mold manufacturing again.
The light diffuser of representing among Fig. 2 10 still has the very irregular profile 3 of shape, and it can be as the same quadrat method manufacturing of introducing previously by the light diffuser 1 of Fig. 1 of being used for.
That represents among Fig. 3 still has a shell 3 that seals by light diffuser 20 another kind of forms of implementation of the present invention, but it is different with the form of implementation of pressing Fig. 1 and 2, has smooth basically that is folding or wrinkling outer surface.This shell 3 still can for example be made by blown film, utilizes the mould of an appropriate design in this case.But this shell also can be by welding a plurality of single thin-film member 3 ' make.
If require the shell 3 of a kind of mechanically stable or rigidity, then shell can certainly have the plate of respective shapes or bonding to make by the material (for example plastics, glass) that blowing or additive method are shaped by the piece that bonds.
With the same in pressing the form of implementation of Fig. 2, shell 3 inside of light diffuser 20 also are provided with the film 7 that can be out of shape arbitrarily.It causes desired illuminating effect equally when this light diffuser of light transmission.
The light diffuser of representing in Fig. 4 30 has the outer enclosure 3 of a rigidity, and it for example can be designed as pyramidal as shown in Figure 4.Outer rigid housing 3 with the stability that is enough to resist extraneous mechanism can be for example with lucite or other any transparent material manufacturings, and certainly any one shape can be arranged.
Many single light diffusers are housed in the inside of outer rigid housing 3, and they itself for example can be designed to as by the light diffuser shown in Fig. 1 to 31,10 or 20.A plurality of perhaps light diffusers of many these classes can be combined into the bigger light diffuser with regulation space structure in this way.
Because the flexibility of each light diffuser,, therefore can obtain desired noticeable optical effect so they can adapt to the outer rigid housing of Any shape and closely cased without difficulty.
Light diffuser also can be packed under the situation that improves temperature by machinery pressurization and/or in order to improve flexibility in the outer rigid housing one by one in case of necessity, so that adapt to the shape of outer rigid housing better and reach the close packing of these light diffusers.
Certainly, these single light diffusers 1,10 or 20 combination also can be carried out in the following manner, that is, under the situation that does not have outer enclosure 3 their are connected and for example be bonded to a kind of needed structure.
Press shell 3 a kind of liquid medium 5 of inflatable still of light diffuser 30 outsides of Fig. 4 itself.As schematically illustrating among Fig. 4, in the outer enclosure 3 of sealing, be provided with the light source 9 of an active or passive type.For example can relate to a kind of low pressure halogen bulb for active light source in this case, then for example can relate to fibre-optic end for the passive type light source.
But this light source not only can be arranged in the form of implementation by Fig. 4 certainly, and can be located at shell 3 inside of a light diffuser in any form of implementation of the present invention.
If light source 9 should adopt a kind of active light source, it must be designed to the liquid sealing certainly so.For example can use luminaire usually for underwater illuminating device.Consider safe reason, the liquid medium around this type of active light source should be nonconducting, to avoid jeopardizing the personnel to this type of light diffuser place under repair under situation about breaking down.
When the active light source that uses in shell 3 inside that are filled with liquid medium 5, its advantage is to obtain a kind of version of extremely saving the space, because this liquid medium can be used as cooling medium again simultaneously, and the power of the active light source loss that is used to loose.
In order to cause desired illuminating effect, transparent liquid medium 5 can certainly dye.Refractive index under any circumstance liquid medium 5 and that be located at wrinkle Zhe film 7 wherein should be different, because otherwise because the complete submergence of wrinkle Zhe film meeting suppresses its refraction or reflecting effect.If the film 7 of the outer enclosure 3 of liquid medium or light diffuser and wrinkle Zhe is dyed different colors, then perhaps can cancel the requirement of different refractivity.
This is equally applicable to this situation,, is combined into a large-scale space structure by a plurality of perhaps how single light diffusers 1,10 or 20 by Fig. 4 that is.If this structure is additionally surrounded by a kind of transparent liquid medium 5, then desired refraction or reflecting effect also can cause like this, that is, the liquid medium in each light diffuser 1,10 or 20 inside should have and each light diffuser different another kind of refractive index of liquid medium on every side.
If light diffuser is not the liquid medium that fills a kind of homogeneous, but fills the mutual immiscible liquid medium that differs from one another, then can obtain other noticeable effects.Do like this and cause the phase boundary that obviously shows, in this case because the different refractive index of liquid medium still can cause corresponding refraction or reflecting effect.
Especially under the situation of large-scale illuminated area, may wish is having reflecting effect on the shell 3 of single light diffuser 1,10 or 20 or on the outer enclosure 3 at the space structure of light diffuser 1,10,20 one by one.This had both related to the light of the external light source that is used for the transmitted light diffusing globe, also related to daylight or other ambient lights injected.For this reason, each or indivedual shell 3 can the whole or local reflecting layer of establishing.This for example can spray the outside or inboard realization of shell by spraying or steam.
Also exist this possibility, promptly shell is provided with a single face reflecting layer, and the light of penetrating from the outside on this light diffuser is reflected in this case, and the external transmissive still of light inside the shell.
