Fig. 1 and Fig. 2 is a specific embodiment of embodiment of the present invention lamp bar; With reference to Fig. 1, Fig. 2, the bar of lamp described in the present embodiment comprises guide rail 1, described guide rail 1 is equipped with at least two substrates 2, described substrate 2 can slide along described guide rail 1, each described substrate 2 is equipped with a pointolite 3, described guide rail 1 is provided with lamp strip electrode 4, and described substrate 2 is provided with the point light source electrode 5 that can make the luminescence of described pointolite 3, when described substrate 2 slides along described guide rail 1, described lamp strip electrode 4 contacts all the time with described point light source electrode 5.
The lamp bar that the embodiment of the present invention provides, can slide along guide rail 1 owing to being with the substrate 2 of pointolite, and lamp strip electrode 4 contacts all the time with point light source electrode 5 in sliding process, therefore after switching on power to lamp strip electrode 4, point light source electrode 5 can be switched on, thus any position of pointolite 3 in guide rail 1 can be lit.Thus, can by each substrate 2 that slides to realize the adjustment fast and accurately to each pointolite 3 spacing.When being adjusted to satisfactory spacing, distance values formal lamp bar sample can be made accordingly.
Further, pointolite 3 can be the point source of light of LED light source, Lamp light source or other types.Due to LED light source, because having, efficiency is high, the advantage of life-span length, not cracky, therefore preferably uses LED light source.
Further, in order to ensure in the process of sliding along guide rail 1 at substrate 2, lamp strip electrode 4 contacts all the time with point light source electrode 5, lamp strip electrode 4 can be made as the strip electrode arranged along guide rail 1, point light source electrode 5 is made as the convex electrode being arranged at substrate 2 upper surface, thus, when substrate 2 slides along guide rail 1 simultaneously, convex electrode can slide along strip electrode and contact with strip electrode, thus any position of pointolite 3 in guide rail 1 can be lit.
In order to make lamp strip electrode 4 more stable with contacting of point light source electrode 5, preferably lamp strip electrode 4 is made as the elastic piece structure of strip, be fixed on elastic piece structure side in the width direction on described guide rail 1, opposite side is in the width direction compressed with described point light source electrode 5 by the elastic force of elastic piece structure and contacts.Thus, in the process that substrate 2 slides, the elastic force by elastic piece structure makes lamp strip electrode 4 and point light source electrode 5 keep more reliably contacting, thus guarantee point light source 3 is lit all the time.
Have multiple by lamp strip electrode 4 mode be fixed on guide rail 1 of elastic piece structure, such as, as shown in Figure 2, can be fixed in described guide rail 1 by embedded for the side of lamp strip electrode 4, this fixed form is more firm, lamp strip electrode 4 difficult drop-off.
Also can as shown in Figure 3, the side of the lamp strip electrode 4 of elastic piece structure be fixed on described guide rail 1 by securing member.This fixed form is convenient to dismounting more.
Particularly, as shown in Figure 3, Figure 4, lamp strip electrode 4 can be two, one is lamp bar positive electrode 41, for connecting with positive source, another is lamp bar negative electrode 42, for connecting with power cathode, two lamp strip electrodes are arranged along the both sides of described guide rail 1 respectively, accordingly, as shown in Figure 3, point light source electrode 5 on substrate 2 is also two, and one is pointolite positive electrode 51, and another is pointolite negative electrode 52, pointolite positive electrode 51 contacts with lamp bar positive electrode 41, and pointolite negative electrode 52 contacts with lamp bar negative electrode 42.Thus, after lamp bar positive electrode 41 and lamp bar negative electrode 42 switch on power, pointolite 3 can be made to be lit.
The structure of guide rail 1 can select various ways, such as, can select two guide rails arranged in parallel, also can select the guide rail of integral type.In order to make with easy to use, the guide rail of preferred employing integral type, as shown in Figure 1, guide rail 1 can be made as Rectangular Plate Structure, and offer gathering sill 11 at the upper surface of guide rail along the length direction of guide rail, then the end of substrate 2 from guide rail 1 is inserted in gathering sill 11, substrate 2 and gathering sill 11 are cooperatively interacted.Thus, the manufacture craft of guide rail 1 is comparatively simple, better can ensure the linearity of guide rail 1, and guide rail in use compared to split type is convenient, does not need extra fixed sturcture, does not also need the correction carrying out the depth of parallelism.
Particularly, various structures can be selected in the cross section of guide rail 1, as fluted body, C type etc., in order to make gathering sill 11 more firm with coordinating of substrate 2, preferred use C type structure as shown in Figure 3, namely extend internally out in the upper surface both sides of guide rail jut 12, and jut 12 can make substrate 2 better coordinate with gathering sill 11, routs up when preventing substrate 2 from sliding in gathering sill 11.
The embodiment of the present invention provides on the other hand a kind of method using lamp bar determination pointolite spacing described in above-mentioned any embodiment, comprises the following steps:
Lamp strip electrode 4 and power supply are connected;
To slide each substrate 2 along guide rail 1, make the spacing consecutive variations of each substrate 2;
When the spacing of pointolite 3 reaches optimal spacing on each substrate 2, determine that each pointolite 3 spacing is described optimal spacing.
The embodiment of the present invention provides the method for optical point source spacing really, can slide along guide rail 1 owing to being with the substrate 2 of pointolite, and lamp strip electrode 4 contacts all the time with point light source electrode 5 in sliding process, therefore after switching on power to lamp strip electrode 4, point light source electrode 5 can be switched on, thus any position of pointolite 3 in guide rail 1 can be lit.Thus, can by each substrate 2 that slides to realize the adjustment fast and accurately to each pointolite 3 spacing.When being adjusted to optimal spacing, optimal spacing value formal lamp bar sample can be made accordingly.Use the method determination pointolite spacing, more fast, accurately.
Further, described optimal spacing can be defined as: in use pointolite minimum number and when there is not light and shade district, the spacing of each pointolite.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
