Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Shown in Fig. 1 and Fig. 2, according to embodiments of the invention, the indicator-lamp cover 2 that lampshade assembly comprises cover body 1 and is disposed on cover body 1, indicator-lamp cover 2 can be one, also can be multiple, indicator-lamp cover 2 extends to second side relative with the first side from the first side of cover body 1, and increases progressively along direction area of section from the first side to the second side, and indicator-lamp cover 2 comprises the first hole of the first side being positioned at cover body 1 and is positioned at the bar hole of the second side of cover body 1.Preferably, the first hole rounding off is to bar hole.
By indicator-lamp cover 2 being designed to the first hole of the first side being positioned at cover body 1 and being positioned at the bar hole of the second side of cover body 1, can install with coordinating of indicator lamp by the first hole is convenient, the display of long strip type, intensive multiple word is realized by strip hole, the entirety that not only can reduce indicator-lamp cover 2 takes up room, make the structure distribution of indicator-lamp cover 2 on cover body 1 compacter, but also intensity of illumination long strip type, intensive multiple word to enough regions can be ensured by bar hole, ensure the display effect of word.
First hole can be circular hole or bar hole, below for convenience of description, with the first hole for circular hole is illustrated each embodiment.
For different word numbers, different word length may be had, if word height is constant, only need the length adjusting bar hole in such cases, width for bar hole need not change the display requirement that can meet word, and the display effect of all words still can be ensured by bar hole, therefore, for the word of different number, larger change can't be caused to the width of adjacent two indicator-lamp covers 2, even if also namely word length increases, also the interval between two adjacent indicator-lamp covers 2 can not be increased, can not increase on the width of bar hole and the volume of cover body 1 is taken, therefore the compact conformation of indicator-lamp cover 2 can be ensured preferably, make indicator-lamp cover 2 can reduce the overall volume of cover body 1 when satisfied display requires.
In the present embodiment, paster LED lamp selected by indicator lamp, circle lamp is compared with SMD lamp, SMD lamp (such as model is the SMD lamp of 3528) lighting angle (lighting angle is α=55 °) is greater than round lamp lighting angle (lighting angle is α=30 °), therefore paster LED lamp is selected can to strengthen the lighting angle of indicator lamp, make the uniformly light-emitting region of indicator lamp larger, improve the display capabilities to indication character.Based on this, the example that is applied as all with paster LED lamp in following each embodiment of the present invention is illustrated the structure of lampshade assembly.According to SMD lamp intensity of light curve, when paster LED lamp lighting angle is at 0 to 20 °, its intensity of light decay is not obvious, when angle is about 26 °, light intensity decays about 10%, when angle is 50 °, light intensity decays about 40%, when angle larger luminous intensity decay to 0 gradually.As long as can ensure that paster LED lamp 9 lighting angle is within 55 °, all can ensureing that paster LED lamp 9 has enough luminous intensities when irradiating indication character, display indication character can be known.Therefore in the present embodiment, the angle between the line at the point in the second side sidewall edge of indicator-lamp cover 2 and indicator lamp center and the center line of indicator-lamp cover 2 is set to be less than or equal to 55 degree.
For the second side sidewall edge of indicator-lamp cover 2, it shows as bar hole, the angle that on bar hole, each point and the line at indicator lamp center and the center line of indicator-lamp cover 2 are formed is not identical, therefore the lighting angle of paster LED lamp 9 is not identical at the diverse location of indicator-lamp cover 2, if but can ensure that the lighting angle of paster LED lamp 9 is limited within 55 degree by indicator-lamp cover 2, the light source so penetrated from indicator-lamp cover 2 meets instruction display needs with regard to having enough luminous intensities.
Preferably, the angular range between the sidewall of indicator-lamp cover 2 and the center line of indicator-lamp cover 2 is 16 to 20 to spend.By limiting the angle between the sidewall of indicator-lamp cover 2 and the center line of indicator-lamp cover 2, can the lighting angle of indicator lamp be limited in the reasonable scope by indicator-lamp cover 2, can ensure that indicator lamp can reach enough large range of exposures when irradiating indication character within the scope of certain lampshade component thickness, the indication character needing to irradiate display can be covered, therefore lampshade component thickness can be made to a certain extent thinning, reduce quality and the materials of lampshade assembly.In addition the lighting angle of indicator lamp is limited between 16 to 20 degree, also can reduces light intensity decays when indicator lamp irradiates, ensure that indicator lamp is to the photo-irradiation intensity of indication character.
Bar hole comprises the arc 3 and straightway 4 that are connected, and straightway 4 is tangent with arc 3, the transition between straightway 4 and arc 3 can be made round and smooth, the adverse effect that the structure that can reduce the link position place of arc 3 and straightway 4 is irradiated indicator lamp.In the present embodiment, bar hole comprises two arcs 3 and two straightways, 4, two arcs 3 are oppositely arranged, and one of them arc 3 is connected to same one end of two straightways 4, and another arc 3 is connected to the other end of two straightways 4.The straightway 4 of two adjacent indicator-lamp covers 2 is disposed adjacent, can make there is uniform interval between adjacent indicator-lamp cover 2, the spacing between two adjacent indicator-lamp covers 2 can be reduced on the basis ensureing clear display indication character, reduce the volume of whole lampshade assembly.
Lampshade assembly also comprises the digital shroud 5 be arranged on cover body 1, is provided with the separation retaining sheet 6 for isolating the light of adjacent two charactrons between digital shroud 5, and the projection of charactron after separation retaining sheet 6 on display perspective plane is non-interference.Digital shroud 5 is mainly used in the display of two 8 patterns, therefore, when designing the digital shroud 5 on lampshade assembly, needs determine the spacing between two adjacent digital shrouds 5 according to the final display image of two 8 patterns, to guarantee the problem that ghost image, image overlap can not occur between two 8 patterns.
Preferably, the emergent light face of digital shroud 5 and indicator-lamp cover 2 is positioned on the same curved surface of cover body 1, the emergent light face of two loophole of 8 patterns and the loophole of indicator lamp is made to be positioned on same curved surface, can prevent because the reasons such as manufacturing tolerance cause two loophole of 8 patterns and the loophole of indicator lamp to occur difference in height on emergent light face, alter light between two 8 patterns and indication character and cause ghost problems, improve the assembling yield issues of lampshade assembly and other structures, improve display effect.
Indicator-lamp cover 2 and the corresponding indicator lamp one_to_one corresponding of lampshade assembly are arranged, and can realize single lamp single hole, can avoid the pattern ghost phenomena that many lamps single hole causes, and improve display effect.
Lampshade assembly is preferably light absorptive material and makes, such as black material.Because the loophole of two 8 patterns is generally aperture, reflectorized material is for the loophole of two 8 patterns, can diffuse reflection be there is and occur the phenomenons such as ghost image, and select the light absorbents such as black material, then can avoid light, through the loophole of two 8 patterns, diffuse reflection occurs well, thus avoid two 8 patterns to occur ghost phenomena, improve the definition of two 8 pattern formings.
Lampshade assembly also includes multiple display lamp hole 12, for setting pressure display lamp.
In conjunction with see shown in Fig. 3 to Figure 16, according to embodiments of the invention, display unit comprises circuit board support 7, display board 8, paster LED lamp 9, lampshade assembly and display floater 10, and display board 8 is arranged on circuit board support 7; Paster LED lamp 9 is arranged on display board 8; Lampshade assembly is arranged on display board 8, and the indicator-lamp cover 2 on lampshade assembly is located on corresponding paster LED lamp 9; Display floater 10 is located at outside lampshade assembly, and the display pattern of paster LED lamp 9 is incident upon on display floater 10.
In conjunction with see shown in Fig. 4 to Fig. 6, lampshade assembly is herein fixed on circuit board support 7 by four screws and two locating dowels, and locating dowel height is more than 3mm, higher than the height of the paster LED lamp on display board 8, prevent from swiping during assembling contraposition paster LED lamp 9, promote assembling yield.The concrete of locating dowel highly can be selected according to the height of paster LED lamp, voluntarily as long as can not hinder the installation of paster LED lamp while positioning lampshade assembly.
Preferably, paster LED lamp 9 is cold light sheet light emitting diode, and the display for indication character or figure and two 8 patterns can have good display effect.Charactron is owing to will show two 8 patterns, and limiting by the installing space on display board 8, is all generally the paster LED lamp 9 of selection of small, chip select shape light emitting diode 3014 (cold light is white) here.Because the decling phase of the light of paster LED lamp 9 is more steady than round lamp, lighting angle is larger, this can be learnt according to the light intensity decays curve of specifications, therefore other pattern lamps except two 8 patterns also select paster LED lamp 9, here chip select shape light emitting diode 3528 (cold light is white), like this for display long strip type word and intensive better effects if.
The specification of paster LED lamp 9 should unification as far as possible, avoids the lamp selecting multiple different size as far as possible, is convenient to the brightness uniformity of adjusting display device like this, adjust the luminance difference of each paster LED lamp 9, make the last display effect of pattern consistent.But due to the restriction of the display space of a whole page, different requirements is had for the size of paster LED lamp 9 and display effect, therefore the specification of the paster LED lamp of two 8 patterns and the paster LED lamp 9 of other patterns inconsistent, needs the paster LED lamp 9 selecting two kinds of specifications when selecting.
In the present embodiment, the specification as the paster LED lamp 9 of indicator lamp is consistent, and the specification being used as the paster LED lamp 9 of the charactron of two 8 pattern displaying is consistent, is convenient to carry out brightness regulation to indicator lamp is unified, or logarithmic code pipe is unified carries out brightness regulation.
In conjunction with see shown in Fig. 7 to Fig. 9, the light source incidence face of display floater 10 has been sticked facial mask 11, and facial mask 11 comprises light absorption unit and hyalomere, and hyalomere is corresponding with the projection of paster LED lamp 9 to be arranged.Specifically, the shape of display pattern on the trypsin method layer that on the light transmission facial mask 11 of paster LED lamp 9, the hyalomere of screen printing pattern projects to display floater 10.The light absorption unit of facial mask 11 can absorb irradiation light, prevents irradiating light and in the process transmitted, diffuse reflection occurs and have influence on the display effect of paster LED lamp 9 on display floater 10.What facial mask 11 adopted is the background color of black, and the position of pattern character is processed into transparent, owing to will be shown to the sprayed coating of outer surface by transparent display floater 10, is spaced one deck medium namely, so need good PET or the PC material of its light transmission.
For the height H of the indicator-lamp cover 2 of lampshade assembly for 5mm, on 3D drawing, its uniformly light-emitting region is Φ 5.4mm (i.e. 26 ° to 30 ° regions), lighting angle region is Φ 10.85mm (i.e. region, 26.57 °, luminous visual angle), when pattern (font length 12.5, width 4mm) is placed in light-emitting zone, pattern brightness irregularities, and pattern edge does not work (because uniformly light-emitting district 5.4mm, and lighting angle region 10.85mm < 12.5mm, pattern cannot be shrouded completely in the lighting angle region of indicator lamp).Due to the restriction of the space space of a whole page, so be designed to by lamp hole be a bit larger tham uniformly light-emitting district, indication character is distributed in uniformly light-emitting district.
When designing, the indicator-lamp cover 2 of lampshade assembly is funnel-form, the section diameter that the circular hole of indicator-lamp cover 2 avoids paster LED lamp is 6.5mm, be greater than more than LED pad locations 0.5mm, angle between the center line of indicator-lamp cover 2 and the sidewall of indicator-lamp cover 2 is 15 ° to 20 ° (shown in Figure 9), and the height of indicator-lamp cover 2 is 12 to 16mm; Gap between the digital shroud 5 of two 8 patterns is 1.4mm, and the height of the digital shroud 5 of two 8 patterns is 9 to 11mm.
In conjunction with shown in Figure 10, for the display unit of the present embodiment, in the design process of reality, the height of indicator-lamp cover 2 is generally designed to 12mm to 16mm, in the present embodiment, the uniformly light-emitting angle design of indicator-lamp cover 2 is α=26.57 °, the height of indicator-lamp cover 2 is designed to H=13.6mm, cd (luminous zone radius)=1.2mm, the height h=1.95mm of paster LED lamp 9, distance K=H-h=13.6-1.95=11.65mm between the light exit plane of paster LED lamp 9 and perspective plane, thus release ec=cd/tan α=1.2/0.5=2.4mm, eo=K+ec=11.65+2.4=14.05mm, can be released by triangle similar quality: cd/ob=ec/eo, ob=eo*cd/ec=14.05*1.2/2.4=7.025mm, so homogeneous area is the scope of diameter D=2*ob=14.05mm, when light is irradiated to facial mask pattern (font length 12.5mm, width 4mm), pattern displaying is even.When the height H of indicator-lamp cover 2 is larger, the scope that can evenly show is larger.Certain H is larger, and the brightness of paster LED lamp 9 can weaken to a certain extent, so will determine to want display effect according to actual conditions, thus under the prerequisite ensuring enough indication ranges, paster LED lamp 9 has enough brightness.
Display floater 10 and display board 8 are sealed in the both ends open place of indicator-lamp cover 2, make all to form confined space between two adjacent indicator-lamp covers 2, the light-illuminating of the paster LED lamp 9 being positioned at an indicator-lamp cover 2 can be prevented to adjacent indicator-lamp cover 2, generation is altered optical phenomenon and causes ghost image, can avoid better interfering between two adjacent paster LED lamps 9, more effectively avoid the problem of ghost image and image overlap, ensure the display effect of indicator lamp.
In conjunction with see shown in Figure 11 to Figure 16, for two 8 sectional hole patterns, when designing, ignore the refraction effect that paster LED lamp 9 occurs in irradiation process, from similar triangles: AB/DE=BC/CE, wherein AB is the hole point on digital shroud 5 and the distance of the irradiation center line of paster LED lamp 9, DE is the imaging of paster LED lamp 9 after the digital shroud 5 represented by AB on display floater 10, CB is the distance between the irradiation center of paster LED lamp 9 and the center of digital shroud 5, CE is the distance between the irradiation center of paster LED lamp 9 and the display surface of display floater 10.
Data according to 3D figure measures:
(1) in conjunction with shown in Figure 12, for the digital shroud 5 that identical two of length bearing of trend are adjacent, CB=9.7mm, CE=9.7+0.35 (thickness of facial mask and double faced adhesive tape)+2 (thickness of display floater)=12.05mm, AB=6.3/2=3.15mm, can release: DE=3.91mm, namely D point is exaggerated relative to A point, the distance increased is 3.91-3.15=0.76mm, so the imaging hole point of two 8 patterns on display floater 10 is apart from being at least greater than 0.76*2=1.52mm, therefore the hole of adjacent digital shroud 5 point distance can be set to be greater than imaging hole point distance, so just can effectively prevent from the point position, hole of two adjacent digital shrouds 5 from pattern occurring to interfere.In the present embodiment, such as the hole of adjacent two digital shrouds 5 point distance is set to 1.9mm, and the gap between the pattern of therefore display on display floater 10 is greater than 1.9mm, also just much larger than the ultimate range 1.52mm that two 8 patterns can interfere on display floater 10, can avoid that pattern occurs and interfere.
(2) in conjunction with shown in Figure 13, for the digital shroud 5 that perpendicular two of length bearing of trend are adjacent, CB=9.7mm, CE=9.7+0.35 (thickness of facial mask and double faced adhesive tape)+2 (thickness of display floater)=12.05mm, FN=2.48mm, FN/ME=CB/CE, ME=3.08mm can be released thus, namely M point is exaggerated relative to F point, the distance increased is 3.08-2.48=0.6mm, so the spacing of the digital shroud 5 of two 8 patterns on display floater 10 at least should be greater than 0.6*2=1.2mm, therefore the minimum range of adjacent digital shroud 5 can be set to be greater than imaging gap, so just can effectively prevent from the point position, hole of two adjacent digital shrouds 5 from pattern occurring to interfere.In the present embodiment, such as, be 1.4mm by the digital shroud 5 of pattern, just can prevent the light source in connected digital shroud 5 from interfering after digital shroud 5 penetrates.
In conjunction with shown in Figure 14, when in a digital shroud 5 through two light sources time, different due to the direction of illumination of two light sources, therefore on display floater 10, the imaging of display is also different, and overlaps, and causes producing ghost phenomena, therefore when designing digital shroud 5, also need to make digital shroud 5 seal up paster LED lamp 9, preventing digital shroud 5 for separating LED light source part, causing lampshade component bottom to alter light and occurring ghost phenomena.
In conjunction with shown in Figure 16, when two 8 pattern lamps of calculating irradiate and do not alter safe altitude and the safety clearance of light, for the charactron specification of two 8 patterns for sheet light emitting diode 3014, the actual amount range finding of DE is from being 2.94mm, the height of digital shroud 5 is 1.5mm, the gross thickness of layers of two-sided and facial mask is 0.2mm, according to the specification of sheet light emitting diode 3014, known CD=1.5-0.3=1.2mm, when gap between two 8 patterns of the light incident side at facial mask 11 is 0.4mm, according to leg-of-mutton similarity principle: CD/CB=DE/AB, 1.2/1.4=2.94/AB, AB=3.43mm, wherein the distance of A point compared with the distance between light source center line between E point and light source center line increases and is of a size of: AB-DE=3.43-2.94=0.49mm ﹥ 0.4mm (two 8 pattern intervals), also namely the irradiation maximum spacing of light from the light incident side of facial mask 11 to exiting side adds 0.49mm, beyond the gap between two 8 patterns on facial mask 11 during design, light can be irradiated in another pattern adjacent with this pair 8 pattern, alter optical phenomenon to produce, cause ghost image.Get on so design does not allow light transmission gap location be irradiated to side pattern, the irradiating angle of logarithmic code shroud 5 is needed to limit, or the spacing strengthened between two 8 patterns adjacent on facial mask 11, thus avoid the range of exposures of sheet light emitting diode 3014 to be greater than gap between adjacent two 8 patterns, avoid altering optical phenomenon when showing two 8 pattern.
In conjunction with shown in Figure 15, due to two 8 patterns project to display floater 10 trypsin method surface time pattern can amplify, when gap between adjacent digital shroud 5 is very little, the pattern that light source irradiation in digital shroud 5 is formed easily coincides together on display floater 10, produce picture registration phenomenon, therefore the irradiating angle controlling digital shroud 5 is needed during bamboo product, or the spacing adjusted between two adjacent digital shrouds 5, can not there is ghost image in the final pattern that two 8 patterns are projected on display floater, can show pattern clearly.The gap between the gap between digital shroud 5 and two 8 patterns on facial mask 11 can be determined by the size calculating the two projected image of 8 patterns on display floater 10 when designing.
Preferably, display floater 10 comprises the base material that grey transparent ABS is made, the transparent ABS injection molding plates of grey is as substrate, on the outer surface of transparent ABS plate, spraying adds silk-screen process, spraying can make the variation of transparent ABS plate color, silk-screen is in order to panel pattern and touch key-press are corresponding, thus the halation making the final display floater 10 formed effectively can filter assembly diffuse reflection to produce, strengthen paster LED lamp 9 by the imaging display effect after lampshade assembly on display floater 10.
