The computer software or system of the present invention can include modeling tool.Modeling tool can be used in production LED light The infield of preplanning LED light display before display and/or in mounted LED lamp display.Modeling tool can be helped The setter of LED light display and/or operator is helped to determine to be located at specific location and include the LED of specific type hood The transmitting boundary of the light of lamp display and the region stopped to the transmitting of light or the region that reduce light transmission.

The present invention relates to the visual angles (or viewing angle) in the horizontal direction used to LED active displays to limit Specific barrier element (that is, hood) method.The hard objectives and hood of the present invention are compared with LED light display The merging of middle LED diodes is to remove the light output on specific direction.The present invention's further objective is that provide one Kind planing method and software/visualization tool, digital display operator to be helped to determine the optimum bit of LED active displays It puts, the light emitting for coming from the display is directed into desired audient and it is visually showed into operator so that institute The LED light display unit shown can be rotated to a certain degree by user, to show that LED light display will in specific installation site The effect of this positioning reached.

Since each installation site may have the special characteristic for the positioning that can influence LED light display, computer Software and system make it possible to be modeled the installation site of LED light display and a variety of may position.Specifically, may be used It is modeled with the positioning of LED light display in the position to LED light display and the position.For example, in modeling process, LED light display may be positioned such that multiple angles of particular locations.It, can be in LED light display as another example LED diodes and the composite construction of hood be modeled, and it can include pixel arrangement and shading cover arrangement (that is, different types of hood will have different-effect, therefore construction of the LED light display comprising concrete type hood can To influence LED light display function and influence target viewing regions and peripheral region).Purpose is real for target viewing audient Existing maximum forward is watched picture quality and scope and is invaded and harassed to the minimum light in photo sensitive area.

The modeling permits a determination that the transmitting of desired light emitting, the transmitting reduced and/or stop, as in LED light Target audience or other residents or the member of element are subjected at selectable position near the potential infield of display Like that.In general, the optimal or preferred infield of LED light display and optimal or preferred installation site will realize display Purpose, such as so that LED light display is visible on the purpose audient of most broad range without influencing picture quality, reduces simultaneously Or stop is to the light emitting of specific region (invading and harassing sensitizing range including light).Instrument in software makes it possible to estimate sensitizing range In final light influence.

In an embodiment of the invention, hood can include the fin for being configured to realize visual angle limitation. For example, this fin can be positioned in horizontal direction close to the stop fin of the LED diodes in LED light display. As another example, barrier element can also include being configured to realize the fin of visual angle limitation, ridge by physical barriers Portion, cupule or physics shading cover portion.

Hood and any visual angle restriction element will be configured to stop or will not substantially stop in the forward direction Light output from LED diodes.The hood and visual angle restriction element constructed herein will position and be designed to keep (being located in target audience region), the member of target audience can watch the angular range of LED light display, this is known as " optimal viewing areas ".Beyond optimal viewing areas, the hood and visual angle restriction element that construct herein will start to hinder It is in the light to the one side to LED diodes.When the angle viewing LED light beyond target viewing regions and optimal viewing areas is shown When showing device, from the percentage of the observable light of LED diodes as the LED diodes in LED light display are blocked element It gradually covers and reduces.

The most of members expectation place and target audience that target viewing regions will be in target viewing audient will The region of LED light display can be watched with minimal visual angle.The border in the region and scope depend on LED light display architectures, Identified target audience region and many aspects of infield.For example, it is watched from the position immediately ahead of LED light display A member in the target audience of LED light display is by the visual angle with 0 degree or slightly larger than 0 degree.Target audience can be with From in the off-centered position viewing LED light display in left or right.By the visual angle in optimal viewing areas really Scope is cut by many aspects depending on LED light display architectures, identified target audience region and infield.Therefore, Angular field of view in target viewing regions, optimal viewing areas and optimal viewing areas for a variety of LED light displays all It is different.

When a people watches LED light display, as visual angle increases, due to hood so that being shown in entire LED light Show that level of illumination is gradually reduced on device.It is the combination of the effect of the gradual increased stop to independent LED element, but also by The difference at the visual angle of different zones on compared with display.With increasing from center visual angle, light emitting is still present with simultaneously And as it can be seen that but with occur in optimal viewing areas and visible transmitting compared with will occur and visible light is less, and And image becomes uneven.The scope at visual angle is known as " transitional region " herein.LED light display will in transitional region It will not be high-visible as in optimal viewing areas.For example, in transitional region, it is shown on LED light display Information may become uneven, full of visible artifacts, and not represent the picture material for it is expected to generate.Therefore, because display Visual quality declines, which should avoid so that the normal target audient of those people for example to drive on highway etc is not Meeting only only minimally passes through the region.With observer in transitional region from closer to optimal viewing areas Position is moved to further from the position of optimal viewing areas, and light emitting will be gradually reduced.Visual angle in transition region it is definite Scope will depend on LED light display shading cover arrangement.

It, will in sufficiently wide level angle, and beyond the farthest edge of the optimal viewing areas of distance of transitional region Can go out and the visible extremely faint light emitting for coming from LED light display or without light emitting occur and it is visible.This Referred to as " light encroachment region ".In the light encroachment region, the transmitting of LED light display light will be obscured only as it can be seen that can not See, therefore, any content of LED light display will be only faint as it can be seen that invisible and usually non-discernable (discernable).As an example, an infield, light encroachment region may be at a distance of LED light display The position that 30 degree of center occurs.It would be recognized by those skilled in the art that in light encroachment region, distance LED lamps show The angle at the center of device will depend on LED light display shading cover arrangement.In light encroachment region, most of LED diodes quilts Barrier element covers, and greatly reduces and completely eliminates light output (i.e. light emitting) in some cases.As an example Son, the present invention a test implementation mode in, the reduction be more than 99 percent (>99%), and due to away under The lateral reflection (indirect paths) of one adjacent barrier element and still retain some light leakage.Angular range in light encroachment region It will be changed according to LED light display, and will be depending on many aspects of LED light display (that is, LED light display In terms of construction), such as voxel model, pel spacing, barrier element material, barrier element construction and design, additionally depend on installation The many aspects in place, such as solar direction, features of terrain, structure, native element etc..

Embodiments of the present invention can provide the software that can be operated in the system of the present invention, to provide visual chemical industry Have that LED light display operation person is helped to assess：(a) include to stop and reduce and come from having for LED diodes Whether the LED light display of the photoemissive hood on body direction is feasible for specific infield；(b) it is used to implement mesh The correct rotation degree of the image quality for the LED light display that target audience in mark audient region is perceived or azimuth The light that (that is, positioning) and the light beyond target audience region invade and harass sensitizing range invades and harasses alleviation；(c) with figure and/ Or text formatting provide with LED light display in the construction of hood in LED light display and/or specific infield Positioning the output of related information, (and this information can be presented to or submit to third party, such as policymaker, to help Determine whether to allow to build this LED light display and mounted on the infield)；And (d) by related with (c) Method, the calculating of computer software and/or the arbitrary illumination pattern of system generation and quantization and therein with infield region The related arbitrary illumination number of degrees.

Computer software and system of the present invention can include Various Components, and can show institute in a variety of formats The information of generation.For example, in an embodiment of the invention, generated information includes following elements：Infield The Interactive Satellite image or top view in region；Barrier element " region " (that is, invade and harass by optimal viewing areas, transitional region and light Region-be shown as illumination pattern) diagram (diagrammatical) represent；To LED in shown image or infield figure The control that the expression of lamp display is positioned and rotated；Pair related with LED light display architectures in infield is other The control of parameter, such as activity show that size and brightness are set；And the parameter related with output estimation.

In general, the element of computer software and system comprising the present invention provides instrument so that can for example exist Describe specific infield to user on the screen of computing device, which for example can be notebook computer, desktop Any one in computer or any mobile equipment, such as cellular phone, smart phone, tablet device, Huo Zheren What it moves equipment.User can utilize the visualization tool of system that the expression of LED light display is located in infield In.The step can be related to：User identifies target audience and the region (mesh in infield where target audience's expectation Mark audient region), and LED light display is positioned facing the target audience.For example, target audience can be identified as public affairs The driver of road, and specific one section of highway can be selected as target audience region.User can show LED light Show that device is positioned facing the target audience region.As another example, target audience can be identified as being located at urban district square Or the people near park, and the specific region in the urban district square or park can be selected as target audience region.User LED light display can be positioned facing to the target audience region.It it would be recognized by those skilled in the art that can be a variety of Plurality of target audient is selected in different zones.

The shading cover arrangement of LED light display can be selected by user.Shading cover arrangement will determine that hood will be to coming from The light of which part LED diode in LED light display is stopped.Therefore, the shading cover arrangement so selected will determine The light emitting occurred from LED light display.

In an embodiment of the invention, system by one or more aspects of infield (for example, building Build object, structure, road surface, trees, topographic feature and other aspects) it is handled, with according to shading cover arrangement and based on coming from The expectation light emitting of LED light display determines optimal viewing areas, transitional region and light encroachment region.The present invention's is other Embodiment can not handle any aspect of infield to determine that optimal viewing areas, transitional region and light are invaded Region is disturbed, and the identification in region can be made according only to shading cover arrangement and based on the expectation light emitting from LED light display Come carry out.

If these regions are not opposite with the requirement of the environment around the requirement of LED light display or LED light display Should, then user can change the position of LED light display using visualization tool.It is, for example, possible to use visualization tool will The different position or carried out to the position of LED light display that the expression of LED light display is moved in the diagram of infield Rotation (that is, by the expression of LED light display from its home position to the right or left side rotation).It can be further using visual Chemical industry has to change construction of the hood in LED light display compared with LED diodes therein.For example, to hood It is constructed to stop more or less light emittings from diode, as described herein, this can be by changing hood Size and/or shape is realized.When carrying out this change to the place of LED light display, position and/or shading cover arrangement, System will generate following as a result, being configured with the results show new place, position and/or hood with LED lamp displays Optimal viewing areas, transitional region and the light encroachment region closed.

As an example, for the LED light display for being located near Highway, it may be necessary to according to highway superior The maximum possible target audience of machine sets this LED light display to the optimal viewing of the information (for example, image) of display Position and/or shading cover arrangement, while limit or reduce to the residential district house, park or other regions of highway both sides The light of (including photo sensitive area) is invaded and harassed.It can be helped a user determine how in specific infield using visualization tool Place, construction and positioning LED light display are to meet the requirement of maximum quantity, and cause image-watching (such as billboard Viewing) value and compromise between being influenced on the minimum local light of community and region it is optimal.This can help user to obtain Approval in the region being not yet given the ratification needed for mounted LED lamp display.It can be given birth to by this method, system and/or software Into report, for being presented to approval main body (such as local policymaker), shown with providing the LED light being mounted in specific region The visual representation of device, and thus generate understanding of the approval main body member to the illumination effects of this installation.

As another example, it may be necessary to being located in the urban district place comprising shopping, business and residential building LED light display is positioned, and the information clearly displayed on such displays is provided with the people into street region, It avoids the light of the house in the region or commercial establishment being invaded and harassed or reduced light invasion simultaneously.It can using visualization tool To help user it is determined that how LED light display is disposed, constructed and positioned in specific infield, pacified with meeting The requirement of the maximum quantity in place to this LED light display is filled (for example, being sent to the information of target audience, to being not present Photoemissive reduction or stop of the environment of target audience etc.).

The present invention can have multiple embodiments.These embodiments are provided compared with the specific excellent of the prior art Point.The LED light display of the present invention and the LED that can operate into create, dispose, construct and/or position the present invention Method, software and/or the system of lamp display realize the irrealizable following achievement of the prior art：(i) so that some regions Light invade and harass minimize with solve be located at this light-emitting diode display near photo sensitive area light invade and harass requirement；(ii) solve ground Ongoing effort of the side's approval main body (for example, government, management tissue etc.) to regulation and this light-emitting diode display installation of limitation； (iii) light emitting being blocked on claimed direction, while kept on the direction for it is expected audient (that is, target audience) The quality of the information (for example, image) shown on LED light display；(iv) reduce in LED light display in horizontal direction Light is invaded and harassed, while realizes the industrial golden standard in the optical property that (rather than compromise) expectation target audient is subjected to；(v) It works with together with dual inline type pin (DIP) ellipse LED；And (vi) due to having modified expectation target audient viewing side Upward light output and the direct light output due to stopping completely on (that is, being only not to reduce) light invasion direction, So that the standard of LED element and optimal optical property in LED light display will not be hindered.

As an example, the present invention can solve and aesthetic, traffic impact caused by prior art LED lamp display The increasingly increased community violent repercussion (backlash) related with shadow sound or invasion.By stopping or reducing in specific side To and/or specific viewing angle on come from the light emittings of LED diodes (and common LED light display), be only located at LED Partial target audient near lamp display receives the direct photoemissive influence from LED light display.Therefore, community Member may be near LED light display, but if they are located at transitional region or light encroachment region, they will be arrived It influences from the photoemissive minimum influence of LED light display or not.

The advantages of present invention is compared with the prior art another example is that the outdoor LED lamps display of the prior art by In its wide angle and the design object of arrival maximum magnitude audient, serious light can be generated certainly and is invaded and harassed.Prior art display Display operation person generally attempt to by by LED light display front from any photaesthesia community ending rotate walk (to be used as One example, about 5-30 degree) it is invaded and harassed to reduce light.However, the half maxima overall with (Full due to these displays Width at Half Maximum, FWHM) angle scope from about 90 degree to 110 degree, therefore the behavior is still inadequate.As a result It is that can only realize minimum light by the way that the front of prior art LED lamp display is slightly rotated away from photaesthesia community Reduce.In addition, the decision-making person of making in ratification process seldom understands illumination effects completely, and often as conservative side and It makes mistakes and (that is, refuses an application), because the branch that they can not quantify for the quantization of the illumination effects of proposal project generation It holds.

The present invention seeks by using the specially designed shading positioned compared with the LED diodes in LED light display The LED pixel pattern of cover and LED light display solves the problems, such as these.The present invention is intended to by being operable to for original The method of position adjustment display installation parameter and the illumination effects in quantitative predication its ambient enviroment, system and/or computer are soft Part program solves the problems, such as these.These elements of the present invention can generate following result：A) LED light display is operable to For to the audient directly facing LED lamp displays or position be in apart from LED light display center minimum angles (no matter The right side or left side at center) audient outstanding picture quality is presented, which is typically relatively narrow angle；b) LED light display beyond minimum angles there may be at the side angle of photo sensitive area or community (for example, side angle position In transitional region or in light encroachment region) light invasion is significantly reduced (for example, reducing about 99% or bigger percentage Than)

Those skilled in the art will appreciate that embodiments of the present invention provide the further advantage for surmounting the prior art.

Following discussion, which provides, is relevant with embodiments of the present invention information.It would be recognized by those skilled in the art that The discussion provides the example of the possible embodiment of the present invention, and other embodiments of the present invention are also possible.

As shown in Figure 1, each LED diodes in LED light display are for example by welding or other connection connects To printed circuit board (PCB) (PCB).As an example, the LED diodes included in LED light display will via one or more Multiple pin stents 126 are stood on PCB 124.LED diodes and PCB constitute display unit, and the display unit is operable Into for sending for the visible light of observer as information or image.It as discussed here, can be into the display unit One step includes display element.

Display unit can be connected to one or more support components.When LED light display is mounted on infield When, one or more support components can be contacted with ground or a part of of one or more support components can be embedding Enter in ground.Support component will be supported on display unit at position above the ground.

The display unit of the present invention can include barrier element.An example such as institute in Fig. 1 for this barrier element Show.LED diodes 1a and 1b are further respectively provided with one or more hoods (that is, barrier element) positioned adjacent. For example, LED diodes 1a has hood 2 positioned adjacent, LED diodes 1b has hood 3 positioned adjacent. (LED diodes 2 have hood 2 and 3 positioned adjacent.) hood 2 stops photoemissive one from diode 1a Point, hood 3 stops the photoemissive part from diode 1b.Shown hood 2 and 3 is included in the present invention's Two possible embodiments of the mechanical stop element in LED light display.It would be recognized by those skilled in the art that can be with There are other constructions of barrier element, such as half round aecidioid, multistage hood or be located to coming near barrier element A photoemissive part for LED diodes generates the barrier element of any other shape of blocking effect.

Polytype barrier element can be included in the LED light display of an embodiment of the invention (as schemed Shown in 3) or in the LED light display of another embodiment of the invention can include single type stop member Part (as shown in fig. 1).

Fig. 1 specifically depicts the combination of the LED diodes with corresponding barrier element that generate certain viewing angles region.

Since the main body of diode serves as the lens around LED wafer (die), LED diodes it is whole A surface sends light.The forward direction viewing arc of LED diodes in LED light display is divided into three different regions by the present invention. The optimal viewing areas 4 of diode is the unencumbered area of any portion of any light emitting from LED diode 1a surfaces Domain.It is the viewing arc not influenced by hood 2 or 3 that diode, which most preferably watches arc,.For bis- poles of all LED of LED light display For pipe, all Regional Representative of the optimal viewing areas of diode optimal viewing areas of LED light display.Work as observer When watching LED light display from the angle in optimal viewing areas, observer will perceive what LED lamps display can be realized Highest image (information) display quality.

Diode transitional region 5 is the region that the part on LED diode 1a surfaces is exposed for viewing.Two In pole pipe transitional region, the light emitting from LED diodes is partially blocked.With the diode mistake in LED diodes 1a The increase of viewing angle in region is crossed, from the maximum angle of the optimal viewing areas 4 of diode to diode light encroachment region 5 Minimum angles, it is from LED 1a, be blocked and watch less than the increase of photoemissive part, and reach the light of observer Transmitting output reduces.In general, the diode transitional region of all LED diodes of LED light display represents LED light The transitional region of display.

When designing the LED light display of embodiments of the present invention, transitional region should be minimized.The target has Two reasons：(a) by transitional region the generation picture quality to be watched of observer be not sufficient to understand viewing and (b) transitional region is not still adequately protected the influence so as to be invaded and harassed from undesirable light.For (a), LED light is shown The target audience of device will cannot understand the information watched and provided over the display from the position in transitional region.In transition region Be not Anywhere in domain optimal display information clarity and quality will with observer in transitional region away from most Good viewing areas is mobile towards light encroachment region and declines.Method, system and/or the computer program of the present invention can operate With by helping user that the application parameter of construction and position of the LED light display in infield is selected to be generated to the greatest extent with optimal Possible small transitional region is located so that target audience and shielded audient are not located in the region, to realize So that the target that the size and scope of angle in transitional region all minimize.

LED diode light encroachment region 6 is all to be covered to all possible direct sight of LED diodes 1a by hood 2 The viewing arc of lid.The region is protected field, is influenced wherein being protected from light and invading and harassing.Specifically, protected field for Photaesthesia personnel or structure near LED light display are favourable, because the light emitting from LED diodes 1a is blocked Up to diode light encroachment region.In general, the diode light encroachment region structure of all LED diodes in LED light display Into the light encroachment region of LED light display.In the light encroachment region, the light emitting from LED light display will reduce Or it eliminates.(in the part closest to transitional region of light encroachment region, the light emitting from LED light display can subtract It is small.As observer can eliminate in transitional region away from the movement of LED light display, light invasion.) interfere the limitation eliminated It is to be likely to occur Indirect reflection on adjacent hood.

As shown in figs. 2 a-2 c, the visible part of LED light display and send towards the observer of LED light display Light quantity is changed based on observer compared with the position of LED light display.For example, as shown in Figure 2 a, if observer is located at The front (that is, being located relative to about 0 degree of angle of LED light display) of LED light display 50, then show over the display Information will be high-visible, and all light emitting will be guided towards observer.In this example embodiment, observer is in optimal In viewing areas.

As another example, as shown in Figure 2 b, if observer from range display center, be enough to make LED Photoemissive at least a portion of diode cannot reach the angle of observer (that is, positioned at apart from the center of LED light display About 20-30 degree angle) viewing LED light display 50, then the information shown over the display is not clear for observer It is visible.At such position, from the point of view of observer visual angle, the photoemissive part from LED diodes is blocked member Part stops, wherein each barrier element is located near at least one LED diodes.Therefore, the light only from LED diodes A part for transmitting reaches observer.In this example embodiment, observer is located in transitional region.

As another example, as shown in Figure 2 c, if observer from range display center, be sufficient so that May no LED diodes light emitting or the angle that is transmitted to up to observer of minimum light (that is, shown positioned at apart from LED light The center of device is approximately greater than 30 degree of angles) viewing LED light display 50, then the information shown over the display for observer and Speech may be sightless.As observer at position, the light emitting from LED diodes can completely or be connect Members block closely is fully blocked, wherein each barrier element is located near at least one LED diodes.It is then possible that one The light emitting reflected a bit may reach observer in the angle.In this example embodiment, observer is located in light encroachment region.

The surface of LED light display can include independent LED diode arrays and associated barrier element.At this In kind construction, some light reflections will inevitably occur.An example of this light reflection is shown in FIG. 3, wherein sending out Raw reflection 7, wherein at least a portion from the LED diodes 1a light sent is guided to hood 3, and is reflected off screening Light shield 3 and reach the eyes 8 of the observer of LED light display.Observer can be located at two poles related with LED diodes 1a In pipe light encroachment region.As a result, even if from the LED diodes 1a light sent be blocked reaching light encroachment region 6 (it is specific and Speech, the light sent on the direction of hood 2 are so stopped), it is sent on the direction of hood 3 from LED diodes 1a A part for light is reflected off hood 3 and enters light encroachment region.This light that will be reached in the light emitting of this reflection The reduction that final light is invaded and harassed in the range of encroachment region is limited in about 99%.

Therefore, as described here, although can be stopped directly towards the light emitting of light encroachment region guiding by hood, But in the range of the light emitting of some reflections can reach light encroachment region, therefore in the four corner of light encroachment region simultaneously Light emitting cannot be completely eliminated.However, since the light emitting only reflected of the part from LED diodes can reach light Encroachment region, therefore compared with the light emitting with occurring in the same area near prior art systems, in light encroachment region The light emitting being subjected to is significantly reduced to close and eliminates.This is because the system of the prior art is not come including any barrier element Stop that any light sent from the LED diodes of LED lamp displays reaches any region related with LED light display, this The scattering of light as caused by due to direct light emitting and/or due to air particles or moisture (such as mist) and occur.Cause This, specifically, Fig. 3 show the combination of LED diodes and corresponding barrier element with a form of barrier properties with And the effect in reflection.

Embodiments of the present invention can include the hood as reflection minimized hood.Reflection minimized hides Light shield can be configured to the light emitting for stopping the part from LED diodes, and also stops and may be located remotely from the one of hood The photoemissive most of reflection partly occurred.Reflection minimized hood can influence the light from multiple LED diodes Transmitting.For example, reflection minimized hood can stop the light emitting of the part from the first LED diodes, and stop and From photoemissive most of reflection of the 2nd LED diodes.If without this stop, the light hair from the 2nd LED diodes The reflection penetrated may be reflected from the part for minimizing hood due to the light of LED diodes and be transmitted to observer.

An example of reflection minimized hood is shown in Fig. 4.Reflection minimized hood 14 can be located at two Between LED diodes 12a and 12b and close to the two LED diodes 12a and 12b.Reflection minimized hood can include There is the light emitting stop arm 15 for being operable to be stopped for the part to the light sent from LED diodes 12b.Reflection The arm 16 close to LED diodes 12a can be further includeed by minimizing hood, which includes reflection blocking flange 9, which is configured to (or inclination) at an angle compared with arm 16 and LED diodes 12a.Reflection blocking is convex The angle of edge is constructed so that the reflection away from arm 16 or away from reflection blocking flange 9 from the LED diodes 12a light sent 11 amount minimizes.Reflection blocking flange is further configured to otherwise carrying out the light reflected from light emitting stop arm Stop, as shown in the light path 17 for being shown as being blocked.

The light emitting stop arm 15b of reflection minimized hood can be further configured for stopping away from another reflection The light 11 for minimizing the reflection blocking flange 9 of hood 14a and reflecting.Therefore, block otherwise can be by for light emitting stop arm The reflected light 11 that observer 13 in light encroachment region sees, as shown in the observable reflected light path 19 being blocked. Therefore, the construction of reflection minimized hood can be designed to stop and directly be sent out close to reflection blocking flange from LED diodes The light gone out, and stop the light reflected from the reflection blocking flange of another reflection minimized hood.

The arm 16 and light emitting stop arm 15s of reflection minimized hood can pass through 21 attaching of connecting portion.This field skill Art personnel are it will be recognized that the connecting portion can be any size and construction, such as the intersection of the arm in U-shaped or V-arrangement link Point, the line part extended between the arm and light emitting stop arm or by the arm be connected to light emitting stop arm it is any its The size and construction of its type.In certain embodiments of the present invention, reflection minimized hood can be constructed such that It is sent from LED diodes and away from the amount of the light reflected a part for the visible hood of observer in transitional region It minimizes.

The reflection blocking flange and its construction of reflection minimized hood are the key that some embodiments of the present invention spies Sign.Reflection blocking flange serves as reflection and reduces element, and is formed to be provided with angle by the part to LED diodes Degree is covered and functioned.Reflection minimized hood can be minimum by the area of the reflecting surface of reflection minimized hood Change, the reflection from the reflecting surface can be reflected and thus become can be by being located in transitional region and/or light encroachment region Observer watch.The region of this reflecting surface is direct reflector space 10.Reflection minimized hood can be further Stop the path of the light away from the reflection of another reflection minimized hood and prevent it from becoming can be by positioned at transitional region And/or the observer in light encroachment region watches.This reflection minimized hood stopped to this reflected light The region on surface be reflected light region 18.

The design parameter and construction of reflection minimized hood must alleviate reflection and the loss of eyefidelity carries out Balance.Construction, design and/or positioning of the reflection minimized hood in LED light display can stop LED diode light A part for transmitting is watched by the observer in optimal viewing areas.

In the embodiments of the present invention for including any type of barrier element, from immediately ahead of LED diodes Position, come from the light emitting of LED diodes and the distribution of light that so sends be mainly derived from the tables of LED diodes The center in face rather than from the periphery on the surface of LED diodes.Most of LED diodes, particularly dual inline type LED diodes (such as the diode generally used in outdoor utility) in pin (DIP) encapsulation have the LED as lens Body so that light is mainly derived from the center of lens rather than from the periphery of lens.Therefore, reflection blocking flange pair The local complexity of the peripheral surface of LED diodes will not be substantially reduced before to light output, but it can the effectively optimal viewing of reduction Region.Embodiments of the present invention can include DIP, and other embodiments of the present invention can not include DIP.

In general, reflection minimized hood may be embodied in LED light display so as to be sent from LED diodes simultaneously remote The visible reflectance of light from a hood part minimizes, and further improves light encroachment region barrier properties.In reflection most After smallization hood is in place, barrier properties have been more than for example existing without any barrier element or other forms block piece The performance of technology light-emitting diode display.Embodiments of the present invention can realize the tremendous increase of barrier properties in light encroachment region, Or the barrier properties more than 99.9%.As a result, embodiments of the present invention can be completely eliminated completely or nearly Whole visibilities of the information presented on LED light display.

The present invention provides the benefit better than the prior art in the ability stopped to the light in light encroachment region.Make For an example, at transitable railway, it may be required that letter cannot be presented in LED light display on the direction of train rail Breath, otherwise the information may be mistakenly considered railway signal lamp by train chief.The present invention is not included near transitable railway Embodiment the prior art LED lamp display meeting for stopping hood and/or reflection minimized hood (in rail On road direction) dim image is sent in light encroachment region, it is thus impossible to meet the LED light near the railway that can pass through The requirement of display.An embodiment of the invention could be configured such that LED light display can include shading The combination of cover and reflection minimized hood.

It would be recognized by those skilled in the art that an embodiment of the invention further can only include is not The barrier element of reflection minimized hood or can only include as reflection minimized hood barrier element or Person includes the combination of polytype barrier element.It would be recognized by those skilled in the art that another embodiment of the invention Reflection minimized hood can only be included without including hood.
