The cross reference of related application

Its full content, by the priority of the U.S. Provisional Application number 61/492,426 of 35U.S.C. § 119 regulation requirement submission on June 2nd, 2011, is incorporated by reference thereto by the application.

Technical field

Present invention relates generally to fully be illuminated the apparatus and method of target area by one or more lightings.More specifically, the present invention relates to the improvement of the design and use of lighting, so that the aiming of the light that can separately project from described lighting and blocking (cutoff) step, to obtain higher motility when affecting the size of lighting, effective projected area or effect in the light demand solving special applications.

Background technology

It is well known that in order to fully illuminate the combination that particularly complex-shaped target area, target area needs the work re-directing (such as, block, reflect) of light directing (such as, aim at, be directed at) and light；For example, with reference to the U.S. Patent number 7,458,700 being incorporated herein in as reference.Generally in Figure 1A-C of the example on the athletic ground for being illuminated by multiple overhead searchlighting lamp-type light fixtures, this design is shown.As seen from Figure 1A, in the state not aimed at, light fixture 4 illuminates some part of target area 5 (it generally not only includes the horizontal plane comprising place, and includes the confined space of described place above and around)；This illumination diagrammatically to illustrate by the light beam 7 projected, and wherein the dash area of light beam 7 is considered as desired.Light fixture 4 is adjusted (such as relative to bar 6, by pivoting around its attachment point) make light beam 7 aim at the leftmost part (referring to Figure 1B) of desired target area 5, and also result defines undesirable illuminated area of such as bleacher 515.It is commonly called this light overflowing light to be waste and there is potential trouble (such as, for the spectators in bleacher 515) or dangerous (such as, for the driver on the highway in adjacent objects region 5).In order to sufficiently eliminate spilling light, it is possible to add shade or similar devices (referring to Fig. 1 C) to provide desired blocking to light fixture 4.Some shade is (at the U.S. Patent number 7 being incorporated herein in as reference, disclosed those in 789,540) it is provided with internal reflection surface to interdict light and to change the direction of described light and return to target area 5 so that it is not absorbed or is wasted.

There is restriction in the method shown in Figure 1A-C.Such as, light fixture 4 is likely to negatively affect effective projected area (EPA) of light fixture relative to the interpolation of the adjustment of bar 6 and shade, and this is likely to increase wind load.Increasing EPA to be likely to need firmer bar or light fixture is fixed to the firmer utensil on bar, both of which is likely to increase cost.Assuming that general very wide region or each bar of sports lighting applications exploiting have multiple bars (for example, with reference to above-mentioned U.S. Patent number 7,458,700) of multiple light fixture, the cost that the change that EPA is small is increased is probably sizable.

As another example, the method in Figure 1A-C is best suited for the light fixture comprising single light source, for instance, above-mentioned U.S. Patent number 7,458,700 and 7,789, the high wattage HID lamp used in 540.It is well known that industry exists the demand producing more effective lighting；Is effectively obtain more light from lamp casing and be irradiated to target area on light fixture its own significance, and is more compact and demonstrate comparable or higher usefulness on light source its own significance simultaneously.Which results in a problem, because when being put in light fixture 4 by multiple small light sources (such as, LED), single shade may not enough make the light of all spillings re-direct and return to target area 5 or offer significantly blocking；This is likely to the uneven illumination of generation, shadow effect or dazzle, and dazzle is probably tedious or potential (such as, the affecting the movement in place) having harm.

Therefore, exist being likely to realize the advantage of the small light source of multiple such as LED (such as in the prior art, long life, high-effect, aim at the ability of multiple point, produce the bigger motility etc. of illumination uniformity) and keep the feature of desired described light fixture (such as, low EPA, high usage etc.) the design requirement of lighting, and there is the method demand that the described light fixture of operation is avoided undesirable lighting effects (such as, non-uniform illumination, shadow effect, dazzle etc.) with the illumination needed for solving target area.

Summary of the invention

Conceive a kind of compact lighting being designed to accommodate that multiple light source, re-direct with light with for independent light directing can have compared with at least most traditional searchlighting lamp-type light fixture in applying with sports lighting and to increase giddy light by dominated, reduce EPA and fully illuminate utensil and the method for complicated target area with increasing illumination uniformity.

Therefore, the elementary object of the present invention, feature, advantage or aspect are improvements over the prior art and/or solve problems of the prior art, item or defect.

According to an aspect of the present invention, a kind of modular unit includes the light source (having the optical component being associated) in multiple housing being contained in shade.Described modular unit is designed to, and the plurality of light source and shade pivot around one, two or three axis, and if it is required, can pivot independently about at least one in described axis.

According to a further aspect in the invention, adjust, relative to its frame high point above target area, the lighting including multiple described modular units, to provide some aiming of the light projected therefrom.It is then possible to adjust each modular unit to provide the further aiming of the light projected therefrom relative to it to the junction point of lighting.Followed by this, or furthermore it is possible to each light source of adjusting selectively and independently of each other in each modular unit and each shade, to provide desired alignment and blocking.In like fashion, the light projected from each modular unit take part in a part for whole illuminations of target area；This allows such as to prevent the motility in the item of dazzle and illumination uniformity in solution.

Referring to appended description and claims, described and other targets, feature, advantage or the aspect of the present invention will become clear from.

Detailed description of the invention

A. summarize

In order to be further appreciated by the present invention, will be described in the specific exemplary embodiment according to the present invention.Explanation will frequently refer to accompanying drawing.Accompanying drawing labelling is used to represent some parts in accompanying drawing.Unless otherwise stated, will be used throughout the drawings identical accompanying drawing labelling to represent identical parts.

Specific exemplary embodiment relates to the searchlighting lamp-type light fixture of sports lighting application；This is undertaken by example and unrestriced mode.Such as, wherein with sports lighting apply compared with it is generally required to less total brightness level (such as, 3 horizon rule candle light (fc) ratio 50 horizontal fc), less illumination uniformity (such as, 10:1 is maximum/minimum more maximum than 2:1/minimum) and reduce docking portion (such as, several feet than near twenty foot), the illumination application of other wide region is likely at least some aspect still benefited from according to the present invention.As another example, downlight (downlight) type light fixture (such as, generally do not tilt relative to their bar or the light fixture that pivots) is likely at least some aspect still benefited from according to the present invention.As yet another embodiment, not high by frame and for sports lighting searchlighting lamp-type light fixture (such as, for the surface-mounted searchlighting lamp-type light fixture of facade illumination) is likely at least some aspect still benefited from according to the present invention.

B. the embodiment 1 of illustrative methods and device

Fig. 2 A-7B has illustrated the instantiation of above-mentioned modular unit.About Fig. 2 A-2F, modular unit 12 is likely to be typically considered and includes housing 22, and housing 22 is formed as receiving shade 23 and outer housing 24, and outer housing 24 is suitable for holding multiple light sources 27 (for example, with reference to Fig. 3 A) with the optics 28 being associated.The opening surface (referring to Fig. 2 F) of lens 29 sealing cover 24 of outside such as, by bonding or band is pricked so that light source breaking-up dust-proof, anti-or other undesirable things, and it is possible if desired to includes anti-reflection coating to keep efficiency of transmission.

Shade 23 is on inner surface (that is, the surface of non-finned) that is that formed by high reflecting material (such as, by aluminum processing to highly reflective) and that be attached to housing 22；Referring to Fig. 2 F.It should be noted that shade 23 can be threaded into, gluing or be otherwise directly attached on the inner surface of housing 22, or can be threaded into, gluing or be otherwise attach on framework, this framework is by the inner surface being attached to housing 22 further；Discussing the example of the reflecting material being attached on framework in above-mentioned U.S. Patent number 7,789,540, this framework is further attached to be used as the housing of shade.Alternatively, the inner surface of housing 22 can be processed (such as, via dipping, coating, chemical deposition, sputtering etc.) to obtain desired finished product with metal.The accurate shape of shade 23 can change according to the demand of application, and material can be processed (such as, peening) or otherwise modify (such as, polishing) to produce required illuminating effect (such as, producing the diffuse-reflectance compared with direct reflection).

In this embodiment, outer housing 24 accommodates nine multi-chip LEDs 27, described nine multi-chip LEDs 27 have such as being most likely in " abaculus " shown in Fig. 6 of above-mentioned application with reference to nine optics being associated discussed in U.S. Provisional Patent Application number 61/539,166 incorporated herein or lens 28 although form this be exemplary and non-limiting way.Such as, outer housing 24 be likely to hold nine can from the XM-L type LED that the Cree company of the U.S. Durham, NC obtains and nine arrow beam of light lens (such as, being similar to the FC-N2-XR79-0R type that can obtain from the Fraen company of the U.S. MA, Reading).Certainly, the light source of the LED of other models, other kinds of light source and other quantity is possible, and is conceived to.Equally, optics 28 potentially includes and is designed to by any distribution mode (such as, middle, ellipse, side-emitted, bubble-shaped etc.) carry out the lens of projection light and can adopt other forms (such as, reflector) or include optional equipment (such as, scatterer, color gel agent etc.) to provide the light directing meeting requirement and/or light to re-direct device to obtain desired illuminating effect.Optics 28 can be glued, be spirally connected or be otherwise attach on the circuit board of light source 27；Alternative it is, optics 28 can positioningly via keeper (such as, generally provided by producer) attached or as with reference to U.S. Patent Application No. 12/751 incorporated herein, 519 (authorize on May 28th, 2013, U.S. Patent number is 8,449,144) keeping by compressed format described in.Finally, people must weigh cost and the size of each modular unit 12 for the brightness degree needed for target area and the uniformity；Wide region illumination application is needed to the sports lighting application of higher total brightness grade, it may be necessary to multi-chip LED (has the optics being associated) provides competitive alternative with the more conventional light source of the HID lamp of such as above-mentioned high wattage relatively.

Housing 22 is suspended in yoke 21 by this way, i.e. allow the pivot of outer housing 24 (and thus, LED27) and housing 22 (and thus, shade 23) around axis 26 separate (referring to Fig. 2 E)；A kind of method that is likely to constructing this modular unit is to obtain this structure shown in Fig. 3 A and 3B.Outer housing 24 is arranged in such a way in the complemental groove of housing 22 (referring to Fig. 2 F and Fig. 3 B) and positioningly attached via plate 30 and corresponding threaded fastener 101, that is, outer housing 24 is limited in its groove of housing 22 but does not hinder the outer housing 24 pivot via pivotal line 26 (it extends referring to Fig. 2 E along the length of outer housing 24).Parts 34 limit the independent angle pivoted of outer housing 24 by the length of the arcuate socket in parts 34, and parts 34 are inserted in the complementary end of outer housing 24 through yoke 21 and housing 22；In this example, it is allowed to rotate 0-45 °, although this is exemplary and nonrestrictive mode.The complementary end of outer housing 24 is mostly for having the blind cylindrical hole of corresponding par.Therefore, when parts 34 slide on the complementary end of outer housing 24, its fastened part 101 is secured together (being fixed to the screwed hole in the complementary end of outer housing 24 Nei) and rotates together.When achieving the desired position of rotation of outer housing 24 (namely, sighting angle) time, it is possible to by being threaded securing member 101 in described arcuate socket and described threaded fastener is tightened in the screwed hole in yoke 21 sidepiece preventing further pivot.In a similar manner, pivotably via sleeve 32 and parts 34, housing 22 is positioningly attached between the arm of yoke 21 by pivotal line 26 (it runs transverse through housing 22 and extends) by not hindering housing 22.Sleeve 32 has smooth outside lateral sides, and it is coupled in the wall of outer housing 22 with in the side opening of flat sides；Therefore, sleeve 32 and housing 22 rotate.The independence being limited housing 22 by the length of the arcuate socket in yoke 21 pivots (left side referring to Fig. 3 A)；Threaded fastener 101 is tightened in the screwed hole in the left side of housing 22 so that housing 22 is clamped to its position of rotation by the arcuate socket of traverse yoke 21.In this example, it is allowed to housing 22 rotates 0-45 °, although this is exemplary and nonrestrictive mode.

Fig. 4 A-C diagrammatically illustrates the independence of outer housing 24 and housing 22 pivot and re-direct step realizing independent light directing and light；For clarity, Fig. 4 A-C illustrates the modular unit 12 intercepted of the tangent line A-A along Fig. 2 E.Fig. 4 A illustrates the first state, the light that wherein each LED27 from outer housing 24 projects collectively form the light beam shown greatly centered by the main shaft 31 that the main shaft 33 with housing 22 overlaps, said two main shaft is all perpendicular to pivotal line 25.Assume the magnitude that total length is several inches of shade 23 and from the magnitude that offset angle is the several years of axis 33, then the magnitude that blocking angle is 6 ° in this first state；As described in this article, blocking angle is defined as the angle between main shaft 31 and shade 23.Outer housing 24 causes the rotation (referring to Fig. 4 B) of main shaft 31 around the pivot of pivotal line 26；This result adds blocking angle (such as, reaching about 35 °) and adds the beam combination motion (that is, light directing) across target area.Housing 22 causes the rotation (referring to Fig. 4 C) of main shaft 33 around the pivot of pivotal line 26；Which results in the blocking from the LED27 light projected and re-direct and change the shape (that is, light re-directs) of beam pattern of target area.Both outer housing 24 and housing 22 are so around the pivot aspect of same point, i.e. make the size of light fixture keep compact and EPA to keep relatively low and unrelated with the angle that blocking angle or light are directed to or re-direct.Additionally, reflection shade 23 allow for differentiated blocking (because light be reflected rather than being absorbed) is provided when not losing efficiency.

Junction point pivot yoke 21 (referring to Fig. 5 A-5D) around yoke 21 to contemplated lighting 10 can be passed through and adjust both outer housing 24 and housing 22 further around the second axis 25 (referring to Fig. 2 E)；Described junction point is likely to identical with described in the U.S. Patent Application No. 12/910,443 incorporated herein as reference with the device from this attachment module gasifying device.In this embodiment, light fixture 10 includes the tubular portion 11 of installation placed in the middle, and this tubular portion 11 is slidedly assemblied on bar 6 or other elevated structures；Structure member 13 contributes to making light fixture 10 stable and centering on bar 6.In order to ensure applicable outdoor application, electric wire from LED27 can be routed in sleeve 32 outside outer housing 24, raceway groove (referring to Fig. 3 A) along yoke 21 outside, is routed to the inside of yoke 21 and is upwards routed in light fixture 10 (referring to Fig. 3 B) by the top center hole in yoke 21；Protective cover 20 assists to shield electric wire relative to environmental effect.Then, from the electric wire of each modular unit by along the laid inside arm 14 of arm 14, tubular portion 11 and bar 6, tubular portion 11 and bar 6 be all general hollow until terminate at electric outer housing 1 place.In a similar manner, being dissipated outer housing 24, housing 22, yoke 21 and arm 14 from the heat of LED27 by outer housing 24, housing 22, yoke 21 and arm 14 is all heat conduction (such as, for aluminum or aluminium alloy structure).The design aspect of modular unit 12 is so, i.e. is shielded relative to environmental effect by electric wire and independently maintains heat dissipation path with aiming at and interdicting；Although other designs of modular unit 12 are possible and are contemplated to.It is it desired to provide further sizable heat sink for LED27 as is it well known, the usefulness of LED and life-span are adversely affected light fixture 10 because increasing junction surface temperature (junctiontemperature) is probably air or liquid active cooling；The method of active cooling light fixture 10 is likely to as described in U.S. Provisional Patent Application number 61/645,870 incorporated herein.

It is possible if desired to arrange the 3rd pivotal line；This allows greater flexibility in the lighting demand of reply special applications and the undesirable elongation of correction projecting beam or location, and described undesirable elongation or location are likely to caused by the pivot around axis 25 and 26.Again consider to illuminate place 5 (referring to Fig. 6 A) by one or more light fixtures 10；In the example it is assumed that projecting beam 7 somewhat wide and shallow (such as, 30 ° × 10 °) and be used for illuminating the rightmost corner, top (also illustrating the expectation part of light beam 7 with hacures) in place 5.By the magnitudes of 45 ° around pivotal line 25 pivot block gasifying device 12 towards desired corner mobile beam 7 (referring to Fig. 6 B), and result rotary beam pattern is (such as, relative to bleacher 515), from without illuminated area 580 fully.Elongate pattern 7 (referring to Fig. 6 C) with the magnitudes of 20 ° around pivotal line 26 pivoting housing 22 and/or outer housing 24 and illuminated the desired corner of target area 5 fully, and result has overflowed light 510.The shape of beam pattern 7 and only rotary beam pattern or compared with changing the size of beam pattern in Fig. 6 C and overflow the beam pattern (referring to Fig. 6 D) creating the desired corner fully illuminating target area 5 with less light in such as Fig. 6 B is substantially changed around the 3rd pivot axis with the magnitudes of 20 °.It is to say, extra pivot the around axis 25 and 26 is likely to throw in more light on place 5 and further reduce spilling light.

As imagination, it is possible to realize the pivot around the 3rd axle by the optics or structure member improving modular unit 12, although arbitrary approach all has advantage and the consideration of himself.Such as, pivot possible simple as rotated lens 28 or applying filter or bubbler to lens 28 around the 3rd axis by improving optics, but the kind of lens that must account for using rotates lens only will slightly change beam pattern, if lens are oval or are asymmetric and by increasing material to lens 28 and cause any loss to efficiency of transmission about axis.Pivot (referring to Fig. 7 A and 7B) by improving the structure member of modular unit around the 3rd axis be likely to the selection without limitation on lens kind and it is also possible to allow shade 23 and pivot and (assume that this is preferred, it may not pivot), but it is likely to add weight and the cost of light fixture 10.Referring to Fig. 7 A and 7B, pivot joint 120 includes modular unit mounting portion 121 and lamp installation part 122, and described each part has the threaded fastener 101 being associated, and if it is required, has nut 102.Improve optics or structure member in either case and provide the rotation around the 3rd pivotal line 35, and to rotate without compromising on pivot and will not interfere significantly on the size of light fixture 10 or EPA around axis 25 and 26 in the way of.

According to method 2000, the light fixture 10 applying multiple modular units 12 as shown in Fig. 5 A-5D can be adjusted to solve the lighting demand (referring to Fig. 8) of special applications, although additive method is possible and is contemplated to around one, two or three axis.According to method 2000, the first step 2001 determines that the illumination scheme of application；Specifically, indicate any limiting factor (such as, general ambient light uniformity, minimum bright level, required inside contract, the size of target area and shape etc.) and desired feature (such as, the colour temperature etc. of the quantity of the modular unit of each light fixture, LED) and research and develop suitable illumination scheme (be also referred to as Lighting Design scheme or aim at sketch).Then, illumination scheme can be broken down into independent beam pattern, and each beam pattern can be assigned to one or more modular unit 12.Next step 2002 is by lamp installation to the target area indicated and/or around according to illumination scheme.The advantage of light fixture 10 is so, i.e. noting because it is centered installation, the position module gasifying device 12 of the tubular portion 11 in Fig. 5 A-5D almost can aim at any direction and can avoid the bridging effect of bar 6；When determining, relative to target area, light fixture is placed into where, this is probably useful.

Next step 2003 is aim at the lighting installed, thus each modular unit 12 aimed in given lighting produces to distribute to its independent beam pattern.It practice, step 2003 potentially includes rotates light fixture 10 and/or around one or more pivotal lines 25/26/35 to pivot one or more parts of modules gasifying device 12 around bar 6.It is possible if desired to utilize degree indicia commonly known in the art or other labellings to mark the part of modular unit 12, in order to lighting designer or other users can arrange sighting angle more accurately.Final step 2004 is that the ability of assessment illumination scheme and light fixture 10 is to meet illumination scheme.Often, lighting designer finds that some thing (such as, stopping the trees of the light from light fixture) not taken into account or client may think that illumination scheme is unsuitable (such as, the profile of light is too dazzling or too soft)；In this situation, it may be necessary to adjust one or more features (referring to optional step 2005) of light fixture.Actually, optional step 2005 potentially includes increases optics 28 to one or more modular units 12, change the pivoting angle (that is, change sighting angle) of one or more parts of light fixture 10, the shape changing shade 23 and/or size, the value volume and range of product etc. of light source that increases modular unit 12 to light fixture 10, adjust the operating power of LED27 producing more or less of light, change in modular unit 12.

C. option and alternative

The present invention is likely to take a lot of form and embodiment.Previous examples is therein several.In order to provide some ideas of some options and alternative, following present several example.

The different utensils and method that are attached on another parts by parts are discussed；It is modal for threaded fastener.Should be understood that this equipment is not limited to bolt or screw, but will be understood that the method (such as, gluing, welding, clamping etc.) including various joint elements.Also discuss the combination of modular unit；Referred to herein as light fixture.It should be pointed out that, that term " light fixture " is often available " luminaire " to replace, and two terms do not have any restriction to what here do not explicitly point out.

, punching press, mold pressing machined by aluminum or aluminium alloy or otherwise formed as imagination, light fixture 10 and the most of parts both modular unit 12.As stated, this provides from the obvious of LED27 heat radiation and continuous print heat passage.But, described parts are likely to be that formed by other materials and without departing from inventive aspect specifically described herein, even without the advantage realizing heat dissipation.Equally, the most of parts in bar 6, light fixture 10 and modular unit 12 are formed with inner passage, such that it is able to make electric wire extend to the bottom of bar 6 from LED27 when not making electric wire be exposed to dampness or other adverse effects.But, described parts likely do not form inner passage and without departing from inventive aspect specifically described herein；Such as, domestic light application carries out environmental protection perhaps without to electric wire.

About modular unit 12, have been presented for several examples of the equipment re-directed for light directing and light；This is way of example and is nonrestrictive mode.Although these equipment any are (such as, lens, scatterer, reflector, shade etc.) can by singly or in combination for special applications, it is noted that, modular unit 12 is not limited to any concrete combination of described parts, design or installation method, if and be suitable for building desired illumination scheme, it is possible to include the auxiliary equipment not described.Such as, if target area includes the confined space above sports ground, then the modular unit 12 of some quantity can be inversely installed to provide illumination upwards, or the arcuate socket in parts 21 and 34 can be extended to allow bigger pivoting angle.As another example, if the horizontal proliferation that lighting designer finds synthesis beam pattern is unacceptable, then can use new lens or existing lens (assuming it is non-symmetrical achromat lens) can be rotated around pivotal line 35, and another solution is likely at the periphery upper mounting rail (reflection or unreflecting) of shade 23 or improves shade 23 to reduce horizontal proliferation.Alternative, one or more light sources 27 are likely to respectively include independent reflector 3000 (referring to Fig. 9), and it is each that this reflector 3000 partly surrounds in described light source；As imagination, the surface at least partially around light source 27 is reflection, although this is citing and nonrestrictive mode.Utilize this alternative, it is necessary to expand the inner chamber of outer housing 24 to provide sufficient gap between the far-end of reflector 3000 and outer lens 29；This can limit the pivotable number of degrees of outer housing 24.Can independent reflector 3000 is gluing, be spirally connected or be otherwise attach on the circuit board of light source 27；Alternative it is, it is possible to keep coming positioningly attached independent reflector 3000 by the retainer described in such as above-mentioned U.S. Patent Application No. 12/751,519 (authorizing on May 28th, 2013, U.S. Patent number is 8,449,144) or compression.

About the illuminator including one or more light fixture 10, may be located remotely from light fixture 10 and power adjusting element is set (such as, driver, controller etc.), and can be disposed at being attached to as shown in Figure 5A and 5B and at the U.S. Patent number 7 incorporated herein as reference, 059, in the electric outer housing 1 on overhead equipment described in 572, or light fixture 10 can be disposed at somewhere.Furthermore, it is possible to as with reference to the scene described in U.S. Patent number 7,209,958 incorporated herein or the control performing power to the light source 27 being contained in light fixture 10 at a distance.Various approach can be taked to provide electric power to the illuminator being combined with modular unit 12, without deviating from inventive aspect described herein.
