Background technology
The light source of developing at present its feature compared with traditional incandescent lamp is the energy efficiency for example improving.The optoelectronic components (being also abbreviated as " LED " in disclosed category) of the emission of light that this example is made up of semi-conducting material, for example inorganic or Organic Light Emitting Diode.But the light atmosphere producing of sometimes experiencing and observer are considered to disadvantageous from the impression of the aesthstic aspect that has the illuminator of this light source and obtain; So there is for example following improvement, the colour temperature that makes corresponding light source is approaching with that colour temperature of traditional incandescent lamp.
The object of the invention is to, propose a kind of compared with prior art favourable illuminator, it has parts photoelectricity, emission of light.
Summary of the invention
According to the object of the invention is to, realize a kind of illuminator, it has printing opacity at least in part, can be also the lamp socket part of transparent lamp housing (Huellkolben), (at least indirectly) carrying lamp housing especially and is the scattering bulb (Streukolben) of at least settling to portion's section scattered beam; In addition scattering bulb is arranged in lamp housing and by lamp socket part (at least indirectly) carrying, wherein in scattering bulb, is provided with parts photoelectricity, emission of light (below be abbreviated as " parts "), in portion's section of scattered beam.
Can in such scope, be for example favourable according to illuminator of the present invention, scattering bulb (wherein having portion's section of scattering) can masking material, at least about certain line of vision.Observer for example that is to say in off-state and can't see parts or at any time indistinctly see, for aesthstic reason, this can be also attracting.
Parts for example can be covered about the line of vision of side (perpendicular to longitudinally seeing of illuminator) and/or the line of vision relevant with " above "; Described illuminator longitudinally on (below be " longitudinally ") lockstep land and arrange lamp socket part and lamp housing, common lamp socket part is in reverse to and is longitudinally placed on base, for example, be inserted in or be screwed on base.If lamp housing has rotational symmetric shape, common rotating shaft is positioned at and is parallel to longitudinal direction.
Be that lamp housing additionally arranges scattering bulb and at this lamp housing internal placement scattering bulb according to the present invention; Under any circumstance " inside " to be positioned at perspective plane or cross section perpendicular to longitudinal direction relevant, and on this face, lamp housing and scattering bulb can have two and intermesh and be connected, and are preferably the shape of concentric circle.May be generally also still other shape of cross section for lamp housing and/or scattering bulb, for example oval shape or may be to there is the such shape of flat sides set equally.
" inside " in the explanation of arranging about parts and scattering bulb be positioned at perpendicular to cross section longitudinal direction, that pass scattering bulb and parts (parts are preferably concentric) relevant; On this cross section, the outer wall area of scattering bulb is around parts.By described outer wall area around area can be larger than the area of the parts of getting on identical cross section, for example in order, be incrementally preferably at least 100%, 200%, 300%, 400%, or 500%.
When now according to the present invention except lamp housing be also provided with can (at least in part) masking material scattering bulb, lamp housing also can be designed as for example transparent, namely (" transparent ") and the parts of printing opacity remain sightless for observer.In so for example aspect such, can be favourable,, while (only having) when comparing with lamp housing little (being positioned at lamp housing inside) scattering bulb by frosted, must be (" the sub-light ") of divergently scattering by less zone design in order to hide identical line of vision.This may be related to cost aspect, for example ought utilize coating come frosted mean additional, depend on surperficial raw materials consumption.
Inventor also emphasizes, in some design lamps, illuminator itself, particularly lamp housing can be parts for design concept; Be related to transparent lamp housing for the overall appearance figure of lamp, this lamp housing is cancelled with respect to the lamp housing of scattering divergently.In illuminator according to the present invention, lamp housing can be designed to outward appearance attracting, be also transparent, and still masking material of scattering bulb.
In preferred design, therefore lamp housing is transparent, and the present invention generally speaking yet relates to the illuminator of the lamp housing with sub-light.
Except lamp housing (lamp housing of sub-light), aspect such, provide advantage according to the setting of the scattering bulb of invention, because can there is the more free degree on scattering Bulb formation.For example, for example, so the shape of lamp housing can be set like this, the requirement based on aesthstic (" outside drawing of traditional sub-light incandescent lamp bulb ") or the normalization based on part aborning recited above; The shape that meanwhile for example can optimize towards such direction scattering bulb, the light adapting in environment distributes, and namely for example penetrates more light in side, or realizes therein light and distribute and the layout of luminous component and the adaptation of location.
(for example divergently/or directionally scattering) portion's section of the scattering of scattering bulb can be regarded " virtual light source " in this respect as; The light of being launched by parts be in brief assigned to other direction by scattering bulb, that is to say and can for example just strengthen to the light emission of a side.
If relate to light transmition in disclosed category, certainly should not comprise the meaning that also must realize corresponding light transmition in order to reach target; This has described a kind of device that is designed for corresponding light transmition.
Light is scattered in " scattering " portion section of scattering bulb, and this is first generally speaking called interaction in disclosed category, for example, utilize scattering center (for example particulate), and this interaction causes light transmition being different from original direction; The direction of result is extremely random distribution.Absorption (pump light) with regard to this some light also can utilize transmitting ensuing Random assignment more or less, that changed by light to describe divergently scattering by fluorescent material particulate.
Generally speaking fluorescent material layer is set to " dispersing scattering " layer like this; Can utilize scattering bulb according to the present invention to save for example fluorescent material based on (comparing with the area of lamp housing) relative little area to be coated.Preferably remain inertia scattering, the deflection that (being launched by parts) light exceeds Random assignment in this inertia scattering is less than for example interacting with scattering center, and particularly wavelength remains unchanged.Generally can also for example in fluorescent material particle, realize inertia scattering, when the excitation wavelength (n) of fluorescent material is positioned at outside the wave spectrum of the light of being launched by parts; Can for example UV-fluorescent material be used as to inertia scattering object on this point.Consult explanation and dependent claims below about the possible of other and preferred inertia scattering object.(" scattering " is abbreviated as " sub-light " or " frosted " at disclosed category.）
Lamp socket part is not must directly support lamp housing and also have scattering bulb, the two (or one of them) can for example also be connected for example plastic casing with lamp socket part by housing.Scattering bulb is directly supported by the supporting member of housing and/or continuation detailed description below.
Preferred embodiment can finding in example in the dependent claims and below of other; Between illuminator, the method for manufacturing it and corresponding application, at length distinguished always; Disclosed content should be understood at least imply whole classifications.
Preferably lamp housing and/or scattering bulb are made up of glass; Corresponding bulb can be for example by blowing, particularly by manufacturing with flipped form (klappform) blowing.Although for lamp housing and/or scattering bulb also can arrange plastic material conventionally, and glass is for example preferred in such scope, this is lower sensitivity for the infringement being caused by UV-light or heat effect conventionally.
Generally speaking lamp housing and/or scattering bulb more may be configured to thin-walled, and this for example also can provide the advantage in weight in conjunction with preferred glass material.The preferred maximum of the wall thickness of lamp housing and/or scattering bulb can be for example 6mm, 5mm, 4mm or 3mm; Do not depend on such upper limit, the minimum of a value of preferred wall thickness can be for example 0.5mm, 0.75mm, 11.25mm or 1.5mm.Equally, the wall thickness distributing in the vertical distributes to change according to the light of expecting.
" diameter " generally speaking represents the mean value being drawn by minimum and maximum in the plane scope in disclosed category, this mean value in the case of preferred circular geometry corresponding to diameter of a circle.
In preferred design, described parts and visible, in the distance of the end of the lamp housing of lamp socket part one side at least 5% of lamp housing length that got in the vertical, visible, in order, increase progressively and be preferably at least 10%, 15%, 20%, 25%, 30%, 35%, 40%; That is to say lamp housing for example by housing lamp socket part one side institute around, for example housing is made up of plastics or pottery, the consideration of length does not just relate to the part that lamp housing extends in housing.
The description of " visible " relates to perpendicular to longitudinal line of vision, namely towards the visual angle, side of illuminator.When parts are when correspondingly compartment of terrain is arranged in lamp socket part end one side, visible lamp housing, also " launch point " of light emission correspondingly can be removed to transfer from lamp socket part and enter lamp housing, this is for optimizing the distribution of light and also can improving designability.
In addition (also isolated with lamp socket part) of corresponding layout simultaneously parts can be for example same because thermodynamic (al) factor is concerned.Be that this can for example also arrange control/driving soft copy (service requirement of general parts, namely it is not for example integrated in parts) in lamp socket part or coupled housing.(emission of light) parts are in operation and can generate heat; In the time that these parts are now arranged at interval with lamp socket part, if desired can dispense temperature and therefore prevent in this case hot-spot.
In preferred design, lamp housing and scattering bulb are directly connected to each other and these two kinds of bulbs also can only be connected to each other indirectly by for example lamp socket part or housing in lamp socket part one side.In the direct interconnected situation of bulb, it can for example be connected and be connected to each other by bonding connection or fusing, and two glass bulbs are for example by glass cement or by the local melting of glass material in the preferred case.
According to application lamp housing and preferably Fluid Sealing ground of scattering bulb, particularly airtightly, be connected to each other.
Between lamp housing and scattering bulb, can further preferably include fluid, for example liquid or preferably gas (it also can exist with the gas mixing).In addition two kinds of bulbs are for example limiting in predetermined air pressure (not with air) or be for example also connected to each other with air, wherein in rear a kind of situation about mentioning, there is this possibility, included air is then by gas instead, for example, by preferably molded adapter on lamp housing.
Generally can realize on this point the intermediate space being evacuated between lamp housing and scattering bulb, still preferably be full of fluid, maybe can provide thermal capacitance for broad light bubble because fluid carrys out cooling scattering bulb (parts equally therefore indirectly) by convection current.
Scattering bulb can perpendicular to lamp housing longitudinally come in directed cross section, for example there is overall diameter, this overall diameter add up to the lamp housing on same cross section interior diameter at least 10%, in order, be incrementally preferably at least 15%, 20%, 25%, 30%.Due to thermodynamic (al) reason, because improvement is cooling, can consider relatively large surface equally.
Preferably scattering bulb is configured to hollow body and the parts layout of turning up the soil with interval, is at least partly; Namely parts are close to the inner wall area of scattering bulb if desired point by point.But general, if can realize the scattering bulb that is substantially constructed to solid, so for example parts can be injected to this scattering bulb; Corresponding scattering bulb can for example have profile and the form fit ground package parts of nozzle-like.
Preferably remain the scattering pipe fitting that is configured to hollow body; This scattering pipe fitting can be for example in inner side, put relative with parts namely, have towards parts, the domes facing to constructing in the direction of parts (" domes " should not be inevitable and mean " smooth " trend, but comprise the shape that for example has formation gradually corner angle or tapering (zulaufende)).Particularly preferably domes are comprising that longitudinal cross section has wedge-type shape and is illustrated in the tip of the wedge shape in parts direction, and namely wedge shape forms in this direction.
Domes can be for example form by walking always of corresponding scattering bulb walls, thereby can be for example to move towards parallel spill with the convex of inwall by the outer wall configuration of scattering bulb; That is to say, after for example formation of the recess by corresponding scattering bulb walls of domes.Inventor points out, can realize by this protuberance the transmitting that improves to side (perpendicular to longitudinally); This is for example particularly in the case of being concerned the parts of emission of light in the vertical according to the emphasis ground of averaging.
Preferably the mounting plane of parts extends and is correspondingly positioned at the main direction of propagation (can this main direction of propagation be formed as to center according to the power of the direction of propagation of estimating) of the light of being launched by parts in the vertical substantially in the direction perpendicular to longitudinal.If other parts are set, these parts are preferably arranged on identical mounting plane, this for example can simplify to manufacture-that is to say and can for example cancel the installation rotatablely moving connecting in the middle of single parts, the parts of multiple side-emitted light are installed around ground, and this rotatablely moves can be for example necessary.Although have emphasis ground in a longitudinal direction the parts of emission of light can also utilize portion's section of the scattering of scattering bulb to realize sideways light to distribute (still can for example upwards separate the light of definite part) always; Conventionally can for example compensate at light and divide the difference of mixing.
Parts are arranged in scattering bulb, rather than are all hidden by portion's section of sub-light about all lines of vision inevitably.Preferably hide about being oriented in all lines of vision perpendicular in longitudinal direction, round; In addition can be preferably hide being in reverse to a side of lamp socket part (line of vision " from upper "), particularly in conjunction with the covering of side.
In a preferred embodiment, parts are namely attached troops to a unit in the line of vision covering of half space about all; Parts have emphasis conventionally in half space emission of light (lamp socket part is not positioned at this half space).
In the preferred improvement project of scattering bulb that is designed to hollow body, parts are arranged in seat member, seat member extends to portion's section of the scattering bulb of divergence of beam scattering in lamp socket part end one side, lamp housing, that is to say at least portion's section in scattering bulb and spaced apart with scattering bulb.Seat member can for example be set to metal or ceramic component and for example by according to shape casting or manufacture by processing, for example turning or sintering.
In addition can select according to thermodynamic (al) boundary condition equally the material of seat member, for example according to the power attenuation of parts; Seat member is also born the function of cooling body on this point.In this external seat member, for example can in the power supply of parts, access equally applicable electric wire or also can design self is the seat member of conduction.
Seat member is arranged in as mentioned in scattering bulb, has at least overall diameter of portion's section, and this diameter is less than the interior diameter of scattering pipe fitting, for example the cross section in the direction perpendicular to longitudinal than the interior diameter of scattering pipe fitting little 5%, 10% or 15%(at least).If for explanation visually, portion's section of the frosted that still broad light does not steep, and seat member (for example, by corresponding application) is all uniform (for example white) at color aspect, and due to less diameter, seat member can be visually unconspicuous/attractive in appearance.
This can be preferably on this point, portion's section of the frosted of scattering bulb is masking material (relating to perpendicular to longitudinal line of vision) more precisely, but do not exceed significantly in the direction towards lamp socket part, preferably do not exceed 10 times, 5 times or 3 times of the component height got in the vertical.
In general the scattering properties of portion's section of scattering also can realize by the scattering center of inserting in " volume materials " of scattering bulb, for example, by air inlet (Lufteinschluesse) or titanium dioxide granule.And preferably adjust scattering properties by surface treatment, this is also favourable aspect cost.
Realize frosted by coating in a preferred embodiment, for example, by silication (silikonisieren).As long as exist about the considering of the environmental suitability of corresponding method, advantage of the present invention starts to work in special mode, when scattering bulb is by frosted and larger lamp housing during not by frosted treats that the area of frosted is less.
Be surperficial roughening for another possibility of surface-treated, for example, by surface erosion or mechanically material etching, for example by polishing or preferably sandblast.
Another possibility for frosted is, on scattering bulb, coats face coat, for example, have organic basic unit (this application can, for example by contaminating, spray or smear to apply) of inserting therein scattering particles.Apply and preferably there is scattering process, for example, the in the situation that of fluorescent material coating; But generally also can on scattering bulb, for example, reflecting layer be set at least partly.
In preferred design, the outer wall area of scattering bulb is surface treated; Then scattering bulb is placed in lamp housing and with this lamp housing and is particularly preferably directly connected.
