It is clamped to its rotation position.In this example, it is allowed to which housing 22 rotates 0-45 °, although this is exemplary and nonrestrictive side
Formula.
The independent of outer cover 24 and housing 22 is diagrammatically illustrated in Fig. 4 A-C to pivot to realize independent light directing and light again
It is oriented to step；For clarity, Fig. 4 A-C show the modular unit 12 along Fig. 2 E tangent line A-A interceptions.Fig. 4 A are shown
First state, wherein collectively form the big main shaft shown with housing 22 from each LED27 in outer cover 24 light projected
Light beam centered on the main shaft 31 that line 33 is overlapped, described two main shafts are all perpendicular to pivotal line 25.Assuming that shade 23 is total
Length is several inches of magnitude and the offset angle from axis 33 is the magnitude in several years, then the blocking angle in the first state is
6 ° of magnitude；As described in this article, blocking angle is defined as the angle between main shaft 31 and shade 23.Outer cover 24 is surrounded
The pivot of pivotal line 26 causes the rotation of main shaft 31 (referring to Fig. 4 B)；This result adds blocking angle (for example, reaching big
About 35 °) and add motion (that is, light directing) of the beam combination across target area.Housing 22 surrounds the pivot of pivotal line 26
Turn to cause the rotation of main shaft 33 (referring to Fig. 4 C)；Which results in the blocking from the LED27 light projected and re-direct and
Change the shape (that is, light is re-directed) of the beam pattern at target area.Both outer cover 24 and housing 22 are around same point
It is so in terms of pivot, i.e. make the size of light fixture keep compact and EPA to keep relatively low and led with blocking angle or light
To or the angle that re-directs it is unrelated.In addition, the use of reflection shade 23 allows to be provided with difference in the case where not losing efficiency
Blocking (because light be reflected rather than being absorbed).
Can be by pivoting yoke 21 (referring to figure around the tie point of yoke 21 to contemplated illuminator 10
5A-5D) come to adjust both outer cover 24 and housing 22 further around second axis 25 (referring to Fig. 2 E)；The tie point and from this
The device put of place's attachment module makeup may with as with reference in U.S. Patent Application No. 12/910,443 incorporated herein
Described is identical.In this embodiment, light fixture 10 includes the tubular portion 11 installed between two parties, the slidable fit of tubular portion 11

21 and arm 14 be dissipated-outer cover 24, housing 22, yoke 21 and arm 14 be all heat conduction (for example, being closed for aluminium or aluminium
Golden structure).The design aspect of modular unit 12 is so, i.e. by electric wire relative to ambient influnence shield and with aiming
Heat dissipation path is independently maintained with blocking；Although other designs of modular unit 12 are possible and are contemplated to.Such as
Fruit wish for LED27 provides it is further it is sizable it is heat sink-as is it well known, LED efficiency and life-span because increasing engagement
Portion's temperature (junction temperature) and be adversely affected-light fixture 10 is probably that air or liquid are actively cold
But；The method of active cooling light fixture 10 may be such as with reference to U.S. Provisional Patent Application No. 61/ incorporated herein
As described in 645,870.
It is possible if desired to set the 3rd pivotal line；This is tackling the lighting demand of special applications and correction projecting beam
Undesirable elongation or positioning in allow greater flexibility, the undesirable elongation or positioning may be by around axles
Caused by the pivot of line 25 and 26.Consider to illuminate place 5 by one or more light fixtures 10 again (referring to Fig. 6 A)；In the reality
In example, it is assumed that projecting beam 7 is somewhat wide and shallow (for example, 30 ° × 10 °) and for illuminating the top rightmost corner in place 5
(the expectation part that light beam 7 is also shown with hacures).By 45 ° of magnitudes 12 directions are put around the makeup of the pivot block of pivotal line 25
Desired corner mobile beam 7 (referring to Fig. 6 B), and result rotary beam pattern (for example, relative to bleacher 515), from
Without fully illuminated area 580.Figure has been elongated around the pivoting housing 22 of pivotal line 26 and/or outer cover 24 with 20 ° of magnitude
Case 7 (referring to Fig. 6 C) and the desired corner for fully illuminating target area 5, and result has overflowed light 510.With
20 ° of magnitude around the 3rd pivot axis substantially change the shape of beam pattern 7-with such as only rotary beam in Fig. 6 B
Pattern or as change in Fig. 6 C the size of beam pattern compared to-and overflow to generate with less light and fully illuminate mesh

The pivot of axle, although any approach all has the advantages that its own and consideration.For example, by improving optical component come around the 3rd
Axis is pivoted may be simply as rotated lens 28 or applying filter or diffuser to lens 28, but must account for institute
The species of the lens used-rotation lens only will slightly change beam pattern, if lens are oval or on axis
Be it is asymmetric-and by lens 28 increase material and cause any loss to efficiency of transmission.By improving modularization
The structure member of device and around the 3rd axis pivot may not be limited (referring to Fig. 7 A and 7B) lens species selection and
It it is also possible to allow shade 23 and pivot (assuming that this is preferred, it may not be pivoted), but the weight of light fixture 10 may be added
Amount and cost.Referring to Fig. 7 A and 7B, pivot joint 120 includes modular unit mounting portion 121 and lamp installation part
122, each part has associated threaded fastener 101, and if desired, with nut 102.In either case
Under-improve optics or structure member-provide rotation around the 3rd pivotal line 35, and surrounded with that will not damage
Axis 25 and 26 pivots and will not significantly affect the size of light fixture 10 or EPA mode rotates.
According to method 2000, it can be adjusted around one, two or three axis using institute in multiple A-5D such as Fig. 5
The light fixture 10 of the modular unit 12 shown is to solve the lighting demand of special applications (referring to Fig. 8), although other method is possible
And be contemplated to.According to method 2000, the first step 2001 is to determine the illumination scheme of application；Specifically, indicate any
Limiting factor (for example, general ambient light uniformity, minimum bright level, it is required inside contract, the size and shape of target area etc.) and institute
Desired feature (for example, quantity, LED colour temperature of modular unit of each light fixture etc.) and the suitable illumination of research and development
Scheme (also referred to as Lighting Design scheme or aiming sketch).Then, illumination scheme can be broken down into single beam pattern
Case, each beam pattern can be assigned to one or more modular units 12.Next step 2002 is will according to illumination scheme
Lamp installation is into the target area indicated and/or around.The advantage of light fixture 10 is so, i.e. because it is centered peace
Position-modular unit 12 of tubular portion 11 in dress-attention, Fig. 5 A-5D can almost aim at any direction and can
To avoid the bridging effect of bar 6；When light fixture is placed into where by decision relative to target area, this is probably beneficial.
Next step 2003 is to aim at installed illuminator, so as to aim at each module makeup in given illuminator
Put 12 and distribute to its single beam pattern to produce.In fact, step 2003 is potentially included rotates light fixture 10 around bar 6
And/or around one or more pivotal lines 25/26/35 come pivot modules makeup put 12 one or more parts.If
Need, it is possible to use degree indicia commonly known in the art or other marks mark the part of modular unit 12, with
Just lighting designer or other users can more accurately set sighting angle.Final step 2004 is to assess illumination scheme and lamp
Have 10 ability to meet illumination scheme.Often, lighting designer finds that some things do not considered (come from for example, stopping
The trees of the light of light fixture) or client may think that illumination scheme is unsuitable (for example, the profile of light is too dazzling or too
It is soft)；In this situation, it may be necessary to adjust one or more features of light fixture (referring to optional step 2005).In fact,
Optional step 2005 is potentially included increases optical component 28 to one or more modular units 12, change one of light fixture 10 or
The pivoting angle (that is, change sighting angle) of multiple parts, the shape and/or size that change shade 23, give the increase module of light fixture 10
