Hereafter for the formation basic theory of the luminous section a1-a4 of door 10 detailed description and construction features.According to being described below, it is possible to be readily appreciated that principle and the structure of other luminous sections.
As shown in Figures 2 and 3, illuminating module 140 is fixed on housing 2.Illuminating module 140 is connected with controlling device 1 (accompanying drawing does not show) by electric wire (accompanying drawing does not show) simultaneously.Light-strip 16 is fixed on door 10, and its light receiver end 161 passes the hole on hinge 12 or gap 18 near illuminating module 140, and relative with illuminating module 140, thus receiving the light launched from illuminating module 140.Light-strip 16 is fixed relative to hinge 12, for instance be connected to the hole on hinge 12 or in gap 18, and the light receiver end 161 of light-strip 16 is not directly connected to illuminating module 140.The light receiver end 161 of light-strip 16 along with door 10 be turned on and off away from or near illuminating module 140.When door 10 is closed, preset clearance between light receiver end 161 and the illuminating module 140 of light-strip 16.
As shown in Figure 4, with the another kind of assembly mode of illuminating module 1400, the light receiver end 1610 of light-strip may is that illuminating module 1400 is fixed on door 10, the electric wire 20 being connected with illuminating module 1400 is connected with the control device 1 being located in housing 2 after hinge 12.
As shown in Fig. 5 to Fig. 8, the illuminating module 140 near hinge 12 comprises a luminous pedestal 141, and four light sources 14 are fixed in luminous pedestal 141.The light launch party of light source 14 is upwards equipped with light-passing board or light-transmissive film 142.What be oppositely arranged with illuminating module 140 is the light receiver end 161 of light-strip 16.The light receiver end 161 of four light-strips 16 is also integrated on a guide-lighting pedestal 162, and is also equipped with light-passing board or light-transmissive film 163 on its light receiver direction.When illuminating module 140 is close to each other with the light receiver end 161 of light-strip 16, the light receiver end 161 of each light-strip 16 is relative with one of them light source 14 respectively, thus receiving the light from light source 14.
Under the control controlling device 1, when the relative distance D of light source 14 and light guide 16 is more than or equal to preset value D0, light source 14 will be closed.Then it is envisioned that be under opening at light source 14, if door 10 is unlocked, the relative distance D between light guide 16 and light source 14 will become greatly, and then light source 14 can be closed.
It addition, when door 10 is progressively closed off, the relative distance D of light source 14 and light guide 16 tapers into during less than or equal to preset value D0, and light source 14 can be opened.It is understood that premise is this timed unit is in "on" position.
The relative distance D of light source 14 and light guide 16 can pass through sensor (accompanying drawing does not show) and record, or at correct position, one microswitch (accompanying drawing does not show) being connected with light source 14 circuit is set, when the relative distance of light source 14 with light guide 16 reaches marginal value, trigger this microswitch, thus closing light source 14.
As shown in Fig. 2 to Fig. 4 and Fig. 9 to Figure 11, the flexible optical fibre that the preferred side of light-strip 16 is guide-lighting, and the cylindrical structural in strip.Light will be launched after entering light-strip 16 from receiving terminal 161 equably from the side, makes the lateral emitting of whole piece light-strip 16.The optical fibers with this characteristic can be buied from the market.
In order to limit the extension path of light-strip 16 with so as to form specific preset shape, for instance in order to obtain the circular ring of light on door 10 as shown in Figure 1, be provided with the guiding groove 22 of overall curved extension in door 10.It addition, the cross sectional shape of guiding groove 22 is the circular arc type that the cross sectional shape with light-strip 16 matches.The outer side covers light-passing board 24 of light-strip 16, so that the light through light-strip 16 can appear from light-passing board 24.Light-passing board 24 forms at least some of of the outer surface of door 10.
In order to obtain the light with apparent edge, the both sides of light-passing board 24 can arrange dark slide 26.The shape of light-passing board 26 can the shape of light-strip 16 adapt.
Owing to the light receiver end 161 of four light-strips 16 on door 10 concentrates in together, in order to obtain as shown in Figure 1 be mutually linked luminous section a1-a4 independent of each other, it is necessary to light-strip 16 is arranged especially.Exemplarily, Figure 10 shows the arrangement of wherein two light-strips 16a, 16b.Hereinafter this is described in detail.
