Description

In illuminating target area, for independence, aim at and interdict device, the method and system of step

The cross reference of related application

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

Technical field

The present invention generally relates to the apparatus and method that fully illuminate target area by one or more lightings.More particularly, 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 flexibility in the situation that can not adversely affect the size of lighting, effective projected area or effect in the light demand that solves special applications.

Background technology

Well-known, in order for example fully to illuminate complex-shaped target area, target area-particularly-need photoconduction, for example, to the combination of the work of the leading again of (, aim at, aim at) and light (, blocking-up, reflect); For example,, referring to the U.S. Patent number 7,458,700 being attached to as a reference herein.Conventionally Figure 1A-the C at the example on the athletic ground for throwing light on by a plurality of overhead searchlight type light fixtures has illustrated this design.As seen from Figure 1A, in the state not aiming at, light fixture 4 illuminates target area 5(, and it generally not only comprises the horizontal plane that comprises place, and comprises top, described place and the confined space around) some part; This illumination by projection light beam 7 use diagram methods illustrate, wherein the dash area of light beam 7 is considered to desirable.With respect to bar 6, for example adjust light fixture 4(, by around its attachment point pivotable) make light beam 7 aim at the leftmost part (referring to Figure 1B) of desired target area 5, and also result has formed for example undesirable illuminated area of bleacher 515.That be commonly called this light that overflows light and be waste and have potential trouble (for example,, for the spectators in bleacher 515) or dangerous (for example,, for a driver on the highway in adjacent objects region 5).In order sufficiently to eliminate and to overflow light, can give light fixture 4 interpolation shades or similar devices (referring to Fig. 1 C) so that desired blocking to be provided.Some shade (in the U.S. Patent number 7,789,540 being attached to as a reference herein disclosed those) is provided with internal reflection surface with blocking light and changes described lamp direction of light and turns back to target area 5 so that it is not absorbed or is wasted.

There is restriction in the method shown in Figure 1A-C.For example, light fixture 4 may adversely affect effective projected area (EPA) of light fixture with respect to the adjustment of bar 6 and the interpolation of shade, and this may increase wind load.Increasing EPA may need firmer bar or light fixture is fixed to the firmer utensil on bar, and the two all may increase cost.Suppose a plurality of bars (for example, referring to above-mentioned U.S. Patent number 7,458,700) that general very wide region or each bar of sports lighting applications exploiting have a plurality of light fixtures, the cost that small change increases to EPA may be sizable.

As another example, the method in Figure 1A-C is best suited for the light fixture that comprises single light source, for example, and the high wattage HID lamp using in above-mentioned U.S. Patent number 7,458,700 and 7,789,540.Well-known, in industry, there is the demand that produces more effective lighting; On light fixture its own significance, be effectively obtain more light and be irradiated to target area from lamp casing, and on light source its own significance, be compacter and demonstrate comparable or higher usefulness simultaneously.This has caused a problem, because for example, when by a plurality of small light sources, (,, while LED) putting in light fixture 4, single shade may not enough make all light overflowing lead to turn back to target area 5 or obvious blocking is provided again; This may produce inhomogeneous illumination, shadow effect or dazzle, and dazzle may be tedious or potential (for example, the affecting the movement in place) that has harm.

Therefore, exist in the prior art to may realize a plurality of for example LED small light source advantage (for example, long life, high-effect, the ability that aims at a plurality of points, produce the larger flexibility of illumination uniformity etc.) and the feature that keeps desirable described light fixture is (for example, low EPA, high usage etc.) the design requirement of lighting, and existence is avoided the method demand of undesirable lighting effects (for example, non-uniform illumination, shadow effect, dazzle etc.) to operating described light fixture to solve the required illumination in target area.

Summary of the invention

Conceive a kind of compact lighting that is designed to hold a plurality of light sources, increase dazzle and control, reduce EPA and increase illumination uniformity utensil and the method that fully illuminates complicated target area with comparing to leading again with light so that with at least most traditional searchlight type light fixture of sports lighting application for photoconduction independently to have.

Therefore, 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 comprises a plurality of being contained in the light source in the housing of shade (having the optical component being associated).Described modular unit is designed to, and described a plurality of light sources and shade be around one, two or three axis pivotables, and if need, can be independently around at least one pivotable in described axis.

According to a further aspect in the invention, the high point of frame with respect to it above target area is adjusted the lighting that comprises a plurality of described modular units, so that some aiming of the light projecting therefrom to be provided.Then, can adjust each modular unit so that the further aiming of the light of projection to be therefrom provided by the tie point to lighting with respect to it.Followed by this, or in addition, can be selectively and adjust independently of each other each light source and each shade in each modular unit, so that desired aligning and blocking to be provided.With which, from the beche-de-mer without spike of each modular unit projection and the part of whole illuminations for target area; This allows the flexibility in solving the item that for example prevents dazzle and illumination uniformity.

B. the embodiment 1 of illustrative methods and device

The instantiation of above-mentioned modular unit has been shown in Fig. 2 A-7B.About Fig. 2 A-2F, modular unit 12 may be considered to comprise housing 22 conventionally, and housing 22 forms and receives shade 23 and outer cover 24, and outer cover 24 is for example suitable for holding a plurality of light source 27(with the optics 28 being associated, referring to Fig. 3 A).The opening surface (referring to Fig. 2 F)-for example of lens 29 sealing covers 24 of outside, by bonding or band prick-so that light source is dustproof, anti-breaking-up or other undesirable things, and if need, can comprise that anti-reflection coating is to keep efficiency of transmission.

Shade 23 is for example, by high reflecting material (, aluminium being machined to highly reflective) inner surface (that is, the surface of non-finned) formation and that be attached to housing 22; Referring to Fig. 2 F.It should be noted that shade 23 can be spirally connected, gluing or be otherwise directly attached on the inner surface of housing 22, or can be spirally connected, gluing or be otherwise attached on framework, this framework is further attached on the inner surface of housing 22; In above-mentioned U.S. Patent number 7,789,540, discussed the example that is attached to the reflecting material on framework, this framework is further attached to the housing as shade.Alternatively, the inner surface of housing 22 can be processed (for example,, via dipping, coating, chemical deposition, sputter 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 (for example, peening) or otherwise for example modify (for example, polishing), to produce required illuminating effect (, producing the diffuse reflection comparing with mirror-reflection).

In this embodiment, outer cover 24 accommodates nine multi-chip LEDs 27, described nine multi-chip LEDs 27 have " abaculus " shown in the Fig. 6 in above-mentioned application of nine optics that are associated discussing in U.S. Provisional Patent Application for example incorporated herein as a reference number 61/539,166 or lens 28-probably although form-this is exemplary and non-limiting way.For example, outer cover 24 may hold nine can be from U.S. Durham, the XM-L type LED that the Cree company of NC obtains and nine arrow beam of light lens (for example, being similar to Ke Cong U.S. MA, the FC-N2-XR79-0R type that the Fraen company of Reading obtains).Certainly, the light source of the LED of other models, the light source of other kinds and other quantity is possible, and is conceived to.Equally, optics 28 may comprise and by any distribution mode (being for example designed to, middle, oval-shaped, side-emitted, bubble-shaped etc.) carry out the lens of projection light and can adopt other forms (for example, reflector) or comprise optional equipment (for example, scatterer, colored gel etc.) with provide the photoconduction that meets the demands to and/or light again guide device obtain desired illuminating effect.Optics 28 can by gluing, be spirally connected or be otherwise attached on the circuit board of light source 27; Alternative, optics 28 can be positioningly for example, via keeper (, conventionally being provided by producer) attached or as U.S. Patent Application No. 12/751,519 incorporated herein as a reference described in by compressed format, keep.Finally, people must weigh for the brightness degree required in target area and the uniformity cost and the size of each modular unit 12; For wide region illumination application, need the sports lighting application of higher total brightness grade, may need multi-chip LED (thering is the optics being associated) to provide competitive alternative with relative for example more traditional light source of the HID lamp of above-mentioned high wattage.

Housing 22 is suspended in yoke shape part 21 by this way, that is, thereby allow outer cover 24(and, thereby LED27) and housing 22(and, shade 23) pivotable around axis 26 separate (referring to Fig. 2 E); A kind of possibility method of constructing this modular unit is to obtain this structure shown in Fig. 3 A and 3B.Outer cover 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 cover 24 is limited in its groove of housing 22 but not overslaugh outer cover 24 via its length along outer cover 24 of pivotal line 26(extend-referring to Fig. 2 E) pivotable.Parts 34 limit the angle of outer cover 24 independent pivotables by the length of the arcuate socket in parts 34, parts 34 are inserted in the complementation end of outer cover 24 through yoke shape part 21 and housing 22; In this example, allow rotation 0-45 °, although this is exemplary and nonrestrictive mode.The complementation end of outer cover 24 is mostly for having the blind cylindrical hole of corresponding par.Therefore,, while sliding on the complementation end of parts 34 at outer cover 24, its fastener 101 is secured together (being fixed in the screwed hole in the complementation end of outer cover 24) and rotates together.When having realized the position of rotation (that is, sighting angle) of the expectation of outer cover 24, can be by threaded fastener 101 being set in described arcuate socket and described threaded fastener being tightened in the screwed hole in yoke shape part 21 sidepieces and prevents further pivotable.In a similar manner, by not overslaugh housing 22, by pivotal line 26(, it runs transverse through housing 22 and extends) mode of pivotable is positioningly attached to housing 22 between the arm of yoke shape part 21 via sleeve 32 and parts 34.Sleeve 32 has smooth outside lateral sides, and it is coupled in the wall of outer cover 22 in the side opening with flat sides; Therefore, sleeve 32 rotates with housing 22.By the length of the arcuate socket in yoke shape part 21, limit the independent pivotable (referring to the left side of Fig. 3 A) of housing 22; Through the arcuate socket of yoke shape part 21, threaded fastener 101 is tightened in the screwed hole in left side of housing 22 so that housing 22 is clamped to its position of rotation.In this example, allow housing 22 rotation 0-45 °, although this is exemplary and nonrestrictive mode.

The independent pivotable that has schematically shown outer cover 24 and housing 22 in Fig. 4 A-C with realize independently photoconduction to the light step that leads again; For clarity, Fig. 4 A-C shows along the modular unit 12 of the tangent line A-A intercepting of Fig. 2 E.Fig. 4 A shows the first state, and being combined to form of the light that wherein each LED27 from outer cover 24 projects shown greatly the light beam centered by the main shaft 31 overlapping with the main shaft 33 of housing 22, and described two main shafts are all perpendicular to pivotal line 25.The magnitude that the total length of supposing shade 23 is several inches and the magnitude that is the several years from the offset angle of axis 33, the blocking angle in this first state is the magnitude of 6 °; As described in this article, blocking viewpoint definition is the angle between main shaft 31 and shade 23.Outer cover 24 has caused the rotation (referring to Fig. 4 B) of main shaft 31 around the pivotable of pivotal line 26; This result has increased blocking angle (for example, reaching about 35 °) and has increased beam combination across the motion of target area (that is, photoconduction to).Housing 22 has caused the rotation (referring to Fig. 4 C) of main shaft 33 around the pivotable of pivotal line 26; This has caused the blocking of the light projecting from LED27 and has led and changed the shape (that is, light leads again) of the beam pattern of target area.Both are so around the pivotable aspect of same point for outer cover 24 and housing 22, that is, make the size of light fixture keep compactness and EPA to keep compared with low and with blocking angle or light is directed to or the angle of guiding is irrelevant again.In addition, the use of reflection shade 23 allows to provide differentiated blocking (because light is reflected rather than is absorbed) in the situation that not losing efficiency.

Can be by the tie point pivotal yoke shape part 21(around yoke shape part 21 to contemplated lighting 10 referring to Fig. 5 A-5D) come further around the second axis 25(referring to Fig. 2 E) adjust outer cover 24 and housing 22 both; Described tie point and may be with described in U.S. Patent Application No. 12/910,443 incorporated herein as a reference from the device of this attached modular unit identical.In this embodiment, light fixture 10 comprises 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 make light fixture 10 stablize and center on bar 6.In order to ensure applicable outdoor application, electric wire from LED27 can be routed in sleeve 32 outside outer cover 24, along the raceway groove (referring to Fig. 3 A) in yoke shape part 21 outsides, be routed to the inside of yoke shape part 21 and be upwards routed in light fixture 10 (referring to Fig. 3 B) by the top center hole in yoke shape part 21; Protective cover 20 assists electric wire to shield with respect to ambient influnence.Then, from the electric wire of each modular unit by the laid inside-arm 14 along arm 14, tubular portion 11 and bar 6, tubular portion 11 and bar 6 be all general hollow-until end at electric outer cover 1 place.In a similar manner, the heat from LED27 is all (for example, being aluminium or aluminium alloy structure) of heat conduction by outer cover 24, housing 22, yoke shape part 21 and be dissipated-outer cover of arm 14 24, housing 22, yoke shape part 21 and arm 14.The design aspect of modular unit 12 is so, that is, by electric wire with respect to ambient influnence shielding and with aim at and interdict independently maintaining heat dissipation path; Although other designs of modular unit 12 are possible and are contemplated to.If wish for LED27 provide further sizable heat sink-as everyone knows, the usefulness of LED and life-span may be air or liquid active cooling because increasing junction surface temperature (junction temperature) be adversely affected-light fixture 10; The method of active cooling light fixture 10 may as U.S. Provisional Patent Application incorporated herein as a reference number 61/645,870 described in.

If need, the 3rd pivotal line can be set; In the undesirable elongation of this lighting demand in reply special applications and correction projecting beam or location, allow greater flexibility, described undesirable elongation or location may be caused by the pivotable around axis 25 and 26.Again consider to throw light on place 5(referring to Fig. 6 A by one or more light fixtures 10); In this example, suppose that projecting beam 7 is somewhat wide and shallow (for example, 30 ° * 10 °) and be used for illuminating the rightmost corner, top (also showing the expectation part of light beam 7 with hacures) in place 5.By the magnitudes of 45 ° around pivotal line 25 pivotable modular units 12 towards desired corner mobile beam 7(referring to Fig. 6 B), and result rotary beam pattern (for example, with respect to bleacher 515), thereby illuminated area 580 fully not.With the magnitudes of 20 °, around pivotal line 26 pivoting housings 22 and/or outer cover 24, elongated pattern 7(referring to Fig. 6 C) and illuminated fully the desired corner of target area 5, and result has been overflowed light 510.With the magnitudes of 20 ° around the 3rd pivotal line rotate the shape changed in fact beam pattern 7-with as rotary beam pattern or compare as changed the size of beam pattern in Fig. 6 C-and overflow the beam pattern (referring to Fig. 6 D) that has produced the desired corner of fully illuminating target area 5 with less light only in Fig. 6 B.That is to say, around the extra pivotable of

axis

25 and 26, may on place 5, throw in more light and further reduce and overflow light.

As imagination, can realize around the pivotable of the 3rd axle by improving optics or the structure member of modular unit 12, although arbitrary approach all has himself advantage and consideration.For example, may be simple as rotation lens 28 or to lens 28 application filter or diffusers around the 3rd axis pivotable by improving optics, but the kind-rotation lens that must consider used lens will be only slight modification beam pattern, if lens be oval-shaped or about axis, be asymmetric-and cause any loss to efficiency of transmission by increasing materials to lens 28.By improving the structure member of modular unit, around the 3rd axis pivotable (referring to Fig. 7 A and 7B), may not can limit the selection of lens kind and may allow shade 23 pivotables (to suppose that this is preferred, it may not pivotable), but weight and the cost of light fixture 10 may have been increased.Referring to Fig. 7 A and 7B, pivot joint 120 comprises modular unit mounting portion 121 and lamp installation part 122, and described each part has the threaded fastener 101 being associated, and if need, has nut 102.In either case-optics or structure member-provide around the rotation of the 3rd pivotal line 35 be provided, and can not damage around

axis

25 and 26 pivotables and can not affect significantly the size of light fixture 10 or the mode of EPA is rotated.

According to method 2000, can adjust the light fixture 10 of a plurality of modular units 12 as Fig. 5 A-5D as shown in of application with the lighting demand (referring to Fig. 8) of solution 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 is to determine the illumination scheme of application; Specifically, (for example indicate any limiting factor, general ambient light uniformity, minimum bright level, required inside contract, the size and shape of target area etc.) and desired feature (for example, the quantity of the modular unit of each light fixture, the colour temperature of LED etc.) and research and develop suitable illumination scheme (being also referred to as Lighting Design scheme or aiming sketch).Then, illumination scheme can be broken down into independent beam pattern, and each beam pattern can be assigned to one or more modular units 12.Next step 2002 is according to illumination scheme by lamp installation in the target area indicating and/or around.The advantage of light fixture 10 is so, that is, because it is centered installation-attention, the position-modular unit 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 with respect to target area, where light fixture to be placed into, this may be useful.

Next step 2003 is to aim at the lighting install, thereby each modular unit 12 aiming in given lighting produces the independent beam pattern of distributing to it.In fact, step 2003 may comprise around bar 6 and rotates light fixtures 10 and/or around one or more pivotal lines 25/26/35, carry out one or more parts of pivotable modules gasifying device 12.If needed, can utilize number of degrees mark commonly known in the art or other marks to mark the part of modular unit 12, so that lighting designer or other users can arrange sighting angle more accurately.Final step 2004 is to assess the ability of illumination scheme and light fixture 10 to meet illumination scheme.Often, lighting designer finds that some thing (for example, stopping the trees from the light of light fixture) or the client that reckon without may think that illumination scheme is unsuitable (for example, the profile of light is too dazzling or too soft); In this situation, may adjust one or more features (referring to optional step 2005) of light fixture.In fact, optional step 2005 may comprise to one or more modular units 12 increase opticses 28, change one or more parts of light fixture 10 pivoting angle (that is, changing sighting angle), the shape that changes shade 23 and/or size, to light fixture 10 increase modular units 12, the operating power of adjusting LED27 to be to produce more or less light, to change the value volume and range of product of the light source in modular unit 12 etc.

C. option and alternative

The present invention may take a lot of forms and embodiment.Previous examples is wherein several just.In order to provide some ideas of some options and alternative, several examples have below been provided.
