Detailed description of the invention
The present invention is a kind of LED lighting assembly in the direction that this inquires into.In order to the present invention can be understood up hill and dale, by following description, detailed step and composition thereof are proposed.Apparently, execution of the present invention be not defined in the those skilled in the art of LED lighting the specific details be familiar with.On the other hand, well-known composition or step are not described in details, to avoid the restriction causing the present invention unnecessary.Preferred embodiment of the present invention can be described in detail as follows, but except these are described in detail, the present invention can also implement in other examples widely, and scope of the present invention not circumscribed, it is as the criterion with the scope of the claims afterwards.
The present invention uses the light of reflective mode output light emitting diode, and the light of light emitting diode directly penetrates by non-immediate, can avoid the generation of dazzling light.Simultaneously, use reflective principle, can by the light after reflection evenly the output changed through selected material, at this moment lampshade can adopt transparent mode or the lighter lampshade of atomized surface effect, can avoid the output reducing light because using heavier cloudy surface lampshade.
Refer to Fig. 3, show the cross section structure schematic diagram of LED lighting assembly of the present invention, the reflector of its middle shell 100 concave surface, the middle section being positioned at concave surface has one to support 110.Support the structure of 110, there are two planes, there is between two planes an angle, and multiple light emitting diode 120 lays respectively in these two planes of support 110.Generally, by LED welding on a printed circuit board (PCB), and then printed circuit board (PCB) can be fixed in support 110.The light that multiple light emitting diode 120 is launched, after the reflection of housing 100, output face injection downwards.The coloured light of multiple light emitting diode 120, can be full white light emitting diode, no matter be the positive white light of cool colour or the white light of warm colour system, or use the light emitting diode of different color light to carry out, also can carry out mixed light, all are according to the light emitting diode needing installation different of user.In figure 3, become the fluorescent tube of a column after a lampshade 130 and housing 100 form, wherein lampshade 130 can be transparent or with any atomized surface effect.
The material of housing 100 can be metallic aluminium, and its inside can add reflector plate, or uses plastics, and its inside adds reflector plate etc.No matter be metallic aluminium or plastics, the mode of extrusion molding can be used to be formed, such as aluminium extruded type housing or the plastics etc. of extrusion.In addition, the material supporting 110 can be identical with housing 100, and be one-body molded.And the material of lampshade 130, usually can use transparent plastics, such as polymethyl methacrylate (PMMA), acryl (Acrylic), polyethylene (PE) or Merlon (PC); And the generation type of lampshade also can use extrusion molding.Connecing and locating at housing 100 and lampshade 130, can design the structure that some are small, promote between the two fixed effect.Meanwhile, the mode of fastener can also be designed by fixing between housing 100 and lampshade 130.
In the middle of some application, just do not consider the illumination immediately below light fixture, simultaneously in order to increase the illumination of light-emitting diode (LED) illuminating lamp at flank angle, as shown in Figure 4 yet, the arc angle of housing 102 or radian can be designed to reduce, such as, be reduced to 120 degree.This mode can increase the lateral light source of LED lighting.Compared to the structure shown in prior art, even if the arc angle of housing 102 is reduced, due to the directive property of light emitting diode, be also difficult to increase lateral light source.But, because the present invention uses reflective design, want the light source increasing side direction easierly to implement.
If the intensity of the light source of side direction does not need too strong, can design cloudy surface shade 140, reduce the light output of side, as shown in Figure 5 between housing 102 and lampshade 132.This structure, particularly suitable, similarly being illumination in office, using several light tube group to synthesize a lamp panel, provides the light source of plane.Such embodiment, be not obtain light source immediately below light fixture, the part immediately below light fixture is non-also can obtain illumination.
Refer to Fig. 6, housing 104 is designed to the arc angle with 180 degree, at this moment, main light all can penetrate toward immediately below.In this type of design, lampshade 134 can adopt cloudy surface lampshade usually, and the light immediately below avoiding can produce dazzles light.
In addition, affecting an important factor of the present invention, is exactly support the distance h between 110 and shell nozzle.This distance h is longer, supports 110 and itself can stop more light; This distance h is shorter, can not stop light although compare, and the light of light emitting diode 120 compares and is not easy to be reflected.
Refer to Fig. 7, when user does not need a complete fluorescent tube time, lampshade 150 also can be designed to plane.Generally, the cost of manufacture of the lampshade 150 of plane usually can be lower.In addition, the transport of product does not also take up space, also can reduce shipment and delivery cost.
Refer to Fig. 8, housing 106 also can be designed to other curved surface, such as oval or parabola.Paraboloidal feature is, when light emitting diode 120 taps into paraboloidal focus, whole light fixture can provide approximate and connect the output of subparallel light.This has the application of demand for special light type, can meet its requirement.The light source of generally traditional fluorescent tube, obtains white light compared to employing cathode-ray exciting mercury vapour, so only have each to even four loose light type, can not provide the collimated light beam of single direction straight-down negative.Be designed to different curved surfaces, light fixture can be allowed to have different light type, mainly determined by application surface.In addition, refer to Fig. 9, housing 108 also can be designed to polygon, and is not limited to curved surface, such as, have five limits or eight limits.
In the middle of the embodiment of above Fig. 8 and Fig. 9, the inside of housing section can be designed to curved surface or the polygon of reservation, but the outside of housing section remains semicircle, so still can design and use semicircular lampshade.
Refer to Figure 10, show the structure of different supports respectively.Between above-mentioned Fig. 3 to Fig. 9, the support 110 of each embodiment, is mainly designed to V-structure, as shown in Figure 10 A.This supporting construction 110 shape is comparatively simple, and can have lighter weight.The another kind design supported is the structure 112 of Y type, as shown in Figure 10 B figure.In addition, time supported design becomes V-structure, the solid of V-arrangement can be become triangle, as Figure 10 C figure shows.No matter be any design, the structure of support all can angle θ folded by two planes, and this angle θ is quite important for impact of the present invention.When angle theta is larger time, the light that light emitting diode major part is launched can irradiate toward the middle section of housing, and the result of reflection has more straight-down negative light, and the light type of whole light fixture has higher directive property; When angle theta is less time, the light that light emitting diode major part is launched can toward the two ends area illumination of housing, and the result of reflection has more sidelight, and the light type of whole light fixture has lower directive property.In addition, the support of Y shape, except angle theta, can also have a parameter, can adjust the position of light emitting diode exactly.An extreme example, as shown in figure 11, the position of light emitting diode 120 supports the design of 112 close to the center of circle of housing 100 by Y shape.
Please refer to Fig. 3, lampshade 130 also can form layer of fluorescent powder layer, produce mixed light with light emitting diode 120.Such as yellow phosphor powder layer and blue light emitting diode light mixing, produce the lighting source of white.Yellow fluorescent powder can be yttrium-aluminium-garnet (YAG) or simpsonite garnet (TAG) or silicate, etc.In addition, the fluorescent material of multiple coloured light also can be used to arrange in pairs or groups the light emitting diode of different coloured light.Such as, use blue light-emitting diode, but use comprises green glow, the fluorescent material of the multi-wavelengths such as ruddiness, or use the fluorescent material of ultraviolet light-emitting diodes collocation three circle looks to blend together white light.The fluorescent material of different color light, can use nitride, sulfide, or silicate etc. is allocated.
In the present invention, due to the equalizing light rays using disposable reflection to carry out light emitting diode, compared to the cloudy surface lampshade using penetration, larger light loss can be avoided, therefore comparatively have an opportunity to provide more uniform highlight illumination.Because supporting construction has two planes at least, between angle can determine that the light type of light fixture has more forward light or sidelight.In addition, when supported design becomes Y-shaped structure, the position of light emitting diode can also be adjusted, have the light type of more conditional decision light fixture.And the reflecting surface of housing, can be circular, parabola, approximate parabola, oval, or other curved surface, or polygonal.Difform housing has conclusive impact for the light type of light fixture.
Apparently, according to the description in embodiment above, the present invention may have many corrections and difference.Therefore need to be understood in the scope of its additional claim, except above-mentioned description in detail, the present invention can also implement widely in other examples.Above are only preferred embodiment of the present invention, and be not used to limit claim of the present invention; Under all other does not depart from disclosed spirit, the equivalence that completes changes or modifies, and all should be included in following claim.
