reflector sections

32,32 ', 32 " be mounted to default structure, these default structures are suitable for the illumination geometric figure that provides predetermined.

A plurality of

reflector sections

32,32 ', 32 of identical or different type " chosen, so that construct main reflector assembly 26 for the lighting pattern that expectation is provided.Then,

reflector sections

32,32 ', 32 " be installed on the base part, the discrete location arrangement that it presented is suitable for providing the lighting pattern of expectation.If need to change the light distribution patterns subsequently, then can reflector sections be taken off from base part 30, and re-construct main reflector assembly 26 as required by any proper device.

First structure of main reflector assembly 26 has been shown in plan view Fig. 8, wherein, top reflector 28 has not been shown.This structure comprises 10

reflector sections

32,32 ', 32 ", described 10

reflector sections

32,32 ', 32 " arrange symmetrically about central axial line AB around the periphery of base port.

Two end reflector 32 " adjacent one another are, adjust each side that aperture 38 is arranged on central axial line AB relatively, symmetrically with lamp.Two end reflector 32 " be arranged to reflector surface central axial line roughly on the direction from B to A towards the aperture 38.Therefore, in operating process, end reflector 32 " both will reflex on the side reflector 32,32 ' from the light of lamp 22, also with its reflection by opening 34.

The side reflector 32 of four broads and two narrower side reflectors 30 ' arrange symmetrically about central axial line AB, have formed around the periphery of opening 34 and have been roughly semielliptical circular arc, and it is centered close to lamp and adjusts on the aperture 38.Two narrower side reflectors 32 ' are arranged on circular arc and adjust place, end farthest, aperture 38 apart from lamp.Reflector surface at the center of arc place is arranged on the roughly direction from A to B approximately at 45 towards central axial line AB.Therefore, in operating process, this circular arc in wide relatively angle upper edge away from the most of light of the roughly direction reflection of adjusting aperture 38 from lamp 22.Maximum part in the reverberation is being reflected with the about angle at 45 of central axial line AB.

The side reflector 32 of two other broad is set at arc end part and end reflector 32 " between.These side reflectors are provided with inwardly with respect to other reflector sections.Therefore, in operating process, described two other side reflector 32 is being adjusted on the roughly direction in aperture 38 at wide angle (～60 ° to～70 °) the antireflection part light with respect to central axial line, just, and at central axial line roughly on the direction from B to A.

Fig. 9 shows by the light pattern roughly that reflector configuration produced shown in Fig. 8.Light from lamp is reflected symmetrically about central axial line AB.The circular arc reflection that the major part of these light is roughly constituted by side reflector on wide angle along direction from A to B, but major part is to be reflected with central axial line AB angle at 45, to produce main elongated areas general as seen at 84.Similarly, two other side reflectors reflect most of light along the roughly directions from B to A at the wide angle (～60 ° to～70 °) with respect to central axial line, to produce generally as the less important elongated area seen at 86.

Be applied in especially by first lighting pattern that provide of structure and be used for the street lamp that thrown light in broad road and zone, pavement (pavement).Luminaire is assembled into and makes main elongated area 84 illuminate road, and the pavement is illuminated in less important elongated area 86.

In plan view Figure 10, can most clearly see second structure of main reflector assembly 28.This structure comprises 9

reflector sections

32,32 ", described 9

reflector sections

32,32 " about central axial line AB symmetrically, around the periphery of base port.

Single end reflector sections 32 " be arranged on symmetrically on the central axial line AB, it is relative to adjust aperture 38 with lamp.End reflector part 32 " be arranged to its reflector surface on the direction of central axial line from B to A towards the lamp mounting portion.Therefore, in operating process, end reflector 32 " both will reflex to from the light of lamp 22 on the side reflector 32, also its reflection is passed through the central opening 34 in the base part.

The side reflector 32 of 8 broads is arranged such that reflector surface has formed two shallow circular arcs, and each shallow circular arc is made of 4 side reflectors 32.As can see from Figure 10, these circular arcs are arranged on each side of central axial line AB symmetrically.Therefore, can see from Figure 11 that in operating process, second constructs the axial patterns that light is reflected into elongation, this pattern is fit to be thrown light in the road surface of traditional width.

Although two kinds of structures that illustrate all provide the light pattern about central axial line AB symmetry, yet, might not need like this, and,

reflector sections

32,32 ', 32 " can be arranged to provide asymmetrical smooth geometric figure.For example, when lamp was set at position near wall, perhaps, for fear of light pollution in one direction, this will be useful.

The independent ability that some heteroid reflector sections are installed provides a kind of like this reflector assembly 26 on basal component, and it can be used to produce multiple illumination geometric figure, guarantees that simultaneously each reflector sections keeps correctly focusing on to lamp.This provides very flexible and effective reflector structure, and this structure can easily be transformed to satisfy different lighting requirements.

Although described the present invention with preferred embodiment about being considered to most realistic now, but, should understand, the present invention is not limited in these disclosed devices, and is intended to cover multiple modification and the equivalent construction that is included in marrow of the present invention and the scope.For example, although preferably, all reflector sections that constitute this reflector assembly can be installed to base part in the optional position in a plurality of discrete locations, so that guarantee greatest possible flexibility, but, also allow in some application scenario the one or more unique prepositions of base part that are installed in these reflector sections, perhaps, even to form with this base part be the part of one.
