For the ease of understanding explanation, thickness direction shown in Figure 3 or cross-sectional direction are elongated with respect to the in-plane (plane direction) of substrate 50 and are exaggerative.
With reference to Fig. 4-6, describe in detail according to the bright district 30 in the pushbutton switch for vending machines of the present invention.For the ease of understanding explanation, in Fig. 5 and 6, the major part of reflecting element 24 has been described mainly equally, or each reflecting surface of first reflecting part 3 and second reflecting part 4, and a part is omitted.
For example, reflecting element 24 has almost distinguishes 30 same elliptical shapes with bright, and for example, reflecting element 24 is by forming such as material injection moldings such as acrylic resins.First reflecting part 3 is located on the position relative with led light source 2.
With each position separately, first reflecting part 3 on, second reflecting part 4 that forms around light source 2 radial (promptly radially) is set on the substrate 50.
First reflecting part 3 covers the place ahead (along the direction of illumination axis Z) of light source 2.First reflecting part 3 can be adjusted to the angle with the subcritical angle that makes from light source 2 with respect to the inclination angle [theta] of X-axis and enter the light of first reflecting part 3 and mix mutually with the light that enters first reflecting part 3 with the angle that is higher than critical angle.In this case, first reflecting part 3 becomes the transmission/reflecting element with transmission function and reflection function.The inclination angle of the refractive index of adjustable material and reflecting element 24 is to reflect whole incident lights.If on the surface of first reflecting part 3, formed reflectance coating, from the light of light source not directly to the illumination direction radiation of pushbutton switch for vending machines 1.The illumination and the light source 2 corresponding positions of push-button switch 1 brightly do not form reflectance coating on the surface of first reflecting part 3 if desired.In addition, can select the refractive index of material and the inclination angle [theta] of reflecting element 24 to reduce the composition that is reflected in the light.
First reflecting part 3 with the corresponding to cross section of optical axis X on be rendered as parabolic shape, each parabola has the focus on light source 2.In this case, the optical axis X of each parabolical central axis Y and light source 2 intersects.Thereby parabolical central axis Y illumination axis Z same and pushbutton switch for vending machines 1 intersects.Preferably, this angle of intersection is almost 90 degree.The arrangement of quadrature can form has the brighter district 30 of minimal thickness.
Parabola rotates and formation parabolic reflector 3a (3b) around the optical axis X of light source 2.In this case, near optical axis X, near light source 2, formed the space of a sealing near the part on parabola summit.Therefore, this space is removed in case from the light of light source 2 to external radiation.
Based on the characteristic of light source 2, can redesign parabolic reflector 3a aptly.For example, if light source 2 only sends light towards the place ahead as the LED lamp, can obtain two parabolic reflector 3a, 3b (equally as shown in Figure 7) by rotation parabola, these two parabolic reflectors appear at the place ahead and rear along the illumination direction of pushbutton switch for vending machines 1, therefore select to be in the parabolic reflector 3a in the place ahead from these two parabolic reflector 3a, 3b.
If light source 2 as incandescent lamp, almost to all the winds sends the light of same intensity, as discussed above, only parabolic reflector 3a is essential.Yet,, can improve utilance from the light of light source 2 if the parabolic reflector 3b at the illumination direction rear is used as first reflecting part 3 (as shown in Figure 7) together.This is favourable to proposing a kind of bright more pushbutton switch for vending machines 1.
First reflecting part 3 is provided with illustrated as top, is reflected at parabolic reflector 3a place from the light of light source 2, and then is reflected to the direction that parallels with parabolical central axis Y.In this case, because parabolic reflector 3a rotates around optical axis X, parabolic reflector 3a causes reverberation to center on optical axis X radial (promptly radially) and sends.
In the present invention, except that first reflecting part 3, also prepare second reflecting part 4.Second reflecting part 4 is positioned on the light path of the light that is reflected from first reflecting part 3, second reflecting part 4 with light to the direction reflection that parallels with the illumination axis Z of pushbutton switch for vending machines 1.
Shown in Fig. 4 and 6, light is sent in first reflecting part 3 in 360 ° scope, and this scope is divided into a plurality of suitable radial districts.In each radial district, each sub-reflecting surface 4a is on the position of the distance that has nothing in common with each other from optical axis X, and all sub-reflecting surface 4a are arranged and have formed second reflecting part 4.When using reflecting surface 4a, the different arrangements of sub-reflecting surface 4a can produce the design variation of luminous shape, such as star.In addition, the reflector shape of sub-reflecting surface 4a can be taked suitable curved surface, as convex surface, concave surface and waved surface, so that scattered reflection light at random.In this case, each second reflecting part 4 can distance optical axis X with equidistant position on to be circular layout.
In order to increase the reflection efficiency of first reflecting part 3 and second reflecting part 4, can be arranged on one or two the reflecting surface in first reflecting part 3 and second reflecting part 4 by the reflectance coating that is constituted such as high reflectance materials such as aluminium.Second reflecting part 4 can separate formation with substrate 50 or form with substrate 50 integral body.
The operation and the effect of the pushbutton switch for vending machines 1 that is constituted according to the present invention have been provided below.In the present invention, be reflected in first reflecting part 3 from the light of light source 2, and from optical axis X along almost horizontal direction expansion, and advance towards second reflecting part 4.Second reflecting part 4 will be reflected the light that comes once more and reflect to illumination direction.Thereby luminescence unit 5 can be made thinner, and light-emitting area can be set arbitrarily.
This means and to set the quantity that is arranged in the light source 2 in the pushbutton switch for vending machines 1 arbitrarily.That is, the appropriate light-emitting area of luminescence unit 5 can offer the required appropriate brightness of pushbutton switch for vending machines 1.Be used in order to prevent to produce the required enough brightness electric weight in addition of whole light-emitting area that illuminates pushbutton switch for vending machines 1 in this area, this point is effective.Aptly, single LED just is enough to illuminate big zone.
Fig. 8 has illustrated the major part of second embodiment of the invention.This second execution mode is main relevant with the structure of second reflecting part.Second reflecting part 4 can be formed by high index of refraction, transparent material.This material has than other transparent materials, as transparent resin, and higher refractive index.
In this example, for example, the prism of approximate right angle is formed on the corresponding position of sub-reflecting surface 4a with second reflecting part 4, on this prism, in the face of the plane of incidence 14b of light source basically with ray intersection from first reflecting part 3.The exit facet 14c of prism intersects with illumination direction basically.The back side 14d of prism is set up at an angle, and this angle can make the light total internal reflection from plane of incidence 14b, and this light total internal reflection is to cause by the refractive index of prism and air is inconsistent.
In this case, illustrated in aforementioned first embodiment of the invention, exit facet 14c can at random adopt suitable curved surface and realize diffusion, these curved surfaces such as convex surface, concave surface and waved surface.In second embodiment of the invention, on part or all the position the position set except that sub-reflecting surface 14a, the reflecting element 24 that is formed by transparent resin material is used at random provide chrominance section, print surface or has the evaporation boosting reflector such as metals such as aluminium thereon.In addition, have reflection function prism 6 can by integral body be arranged on second reflecting part 4 near.
Fig. 9 and 10 has illustrated the 3rd execution mode of the present invention.In aforesaid second execution mode, second reflecting part 14 (sub-reflecting surface 14a) is made up of transparent resin material.Can find that by observing such pushbutton switch for vending machines 1 almost each light-emitting area is all covered by a transparent element.
Therefore, in third embodiment of the invention, reflecting element 24 has plane of incidence 24b and back side 24d, and plane of incidence 24b is configured to similar with the back side to the plane of incidence of the second execution mode neutron reflection face 14a with back side 24d.In addition, although not shownly go out, can chrominance section etc. is located on the position except that the set position of sub-reflecting surface 24a.
In third embodiment of the invention, luminescence unit 5 be provided with to first execution mode in illustrated similar sub-reflecting surface 4a, described luminescence unit 5 is positioned at after the reflecting element 24, can at random obtain the required irradiates light of light fixture from sub-reflecting surface 4a and 24a like this.
Be assigned with in such a way from the light of first reflecting part, 3 reflections, promptly the part near reflecting element 24 is reflected at sub-reflecting surface 24a place, and is reflected at sub-reflecting surface 4a place near the part of luminescence unit 5.In this case, owing to prevented that the part in the each several part from having hindered other parts, therefore as shown in figure 10, send light on two can be in coming from the same fan section A of light source 2 overlapped positions.
Figure 11 has illustrated four embodiment of the invention.In aforesaid each execution mode, the push-button switch 1 of automatic vending machine can be made of a plurality of luminescence units 5.In this case, each luminescence unit 5 is arranged in the mode of non-overlapping copies.The present invention is not subject to this kind arrangement mode, can be used in the multistage overlapping arrangement mode yet.
The second radiating portion 4D of luminescence unit 5D is positioned at lower position, and the second radiating portion 4U of luminescence unit 5U is positioned at the top position, and the second radiating portion 4D and the second radiating portion 4U can be arranged on the position of non-overlapping copies vertically.In this case, not interrupted and can directed illumination direction from the light of the luminescence unit 5D of below.This overlapping can being applied in naturally in two or more levels.
Preceding structure is to illustrate under such hypothesis, promptly below the light source 2D of luminescence unit 5D and the light source 2U of luminescence unit 5U up connected simultaneously., in this embodiment, always do not need described two light sources are connected simultaneously.For example, only a level is switched on after commodity are sold, and only another grade is switched on the state that expression normally can be bought, and when certain philtrum prize when waiting, a plurality of grades are switched on.The conversion of this brightness or color has especially improved the attraction of commodity for client.
The following describes fifth embodiment of the invention.In aforesaid execution mode, reflecting element 24 has and the bright 30 identical elliptical shapes of distinguishing.This reflecting element 24 is by such as transparent material injection mouldings such as acrylic resins and form; And this reflecting element 24 be included in led light source 2 relative positions on first reflecting part 3.With position separately, first reflecting part 3 on, be arranged on substrate 5 or the analog around second reflecting part 4 of light source 2 radial formation.
Yet in the present embodiment, reflecting element 40 comprises first reflecting part 3 and second reflecting part 4, and the two is formed by integral body.

The operation in the auxiliary bright district set according to the present invention is described below.Usually, after required amount is put into automatic vending machine 100, thereby bright district 30 just is activated lighting button fully always, for example, shows that orange expression has been ready to sell.Yet, if commodity are sold, just appear on the part of button 1 such as " selling off " or characters such as " selling " always, sold light to show with the corresponding commodity of this button.
Equally in the present invention, as shown in figure 17, be located at the first through hole 7a in the auxiliary viewing area 7 and be positioned at and be switched on to show the character of " selling off " or " selling " with the corresponding locational red LED light source 2N of the first through hole 7a.Meanwhile, even insert coins to automatic vending machine, because the use of computer or analog, the bright district 30 of corresponding button 1 can not start yet.Character " is sold off " or " selling " starts demonstration continuously, after commodity are replenished.
The operation of the second through hole 7b is described below.Orange led light source 2H2 be positioned at the corresponding position of the second through hole 7b on, and demonstrate such as " preparation " or characters such as " preparations " with the corresponding filter element 22 of the second through hole 7b, these characters are consistent with the distribution state of institute's merchandising in the automatic vending machine 100.
As discussed above, beverage or analog often are frozen or heat the back and sell, if they are just taken out after in being supplied to automatic vending machine 100 immediately, although should be heated or freezing, but they still are in the normal temperature state.Here it is so-called warm nature state, it makes the consumer dissatisfied.In order to prevent this state, button 1 of the present invention is provided with the second through hole 7b.When as shown in figure 18 demonstration is activated, it has shown that commodity are positioned heat or cold state, thereby prevented that the consumer from buying commodity at once after automatic vending machine is supplied, and prevented because commodity are cooled or heat not enoughly and cause the consumer to feel under the weather.
Figure 19 has illustrated the 7th execution mode of button 1 of the present invention.In aforesaid the 6th execution mode, constituted second reflecting surface 4 in bright district 30 and constituted and assisted the first through hole 7a and the second through hole 7b in bright district 31 to be formed by integral body.In addition, throw light on led light source 2N, the 2H2 of the first through hole 7a and the second through hole 7b of the led light source 2C and being used to of second reflecting surface 4 that be used to throw light on is positioned at single space.Therefore, for example, when bright district 30 was activated, the character in auxiliary bright district 31 might be seen more brightly.
In order to address this problem, in the 7th execution mode, be formed with the element of first reflecting surface 4 on it and be formed with the element of the first through hole 7a and the second through hole 7b in it isolated.In addition, switch 51 is in the residing position of led light source 2C of second reflecting surface 4 that is used to throw light on between the residing position of led light source 2N, 2H2 of be used to the to throw light on first through hole 7a and the second through hole 7b.So just considered and prevented two kinds of interference between the light.In addition, the surface element 21 that covers in the bright district 30 is separated with the surface element 21a that covers in the auxiliary bright district 31, thereby prevents two interference between the light as far as possible longways.Thereby the present invention can be different and at random be redesigned according to purpose, and illustrated part-structure is not construed as limiting the present invention in Fig. 3,12,13 and 19 general view and other accompanying drawings.
