Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of lamp bar 100, described lamp bar 100 comprises printed circuit board (PCB) (Printed Circuit Board, PCB) 10, at least one light source 20 and at least one lens 30, wherein, described light source 20 is arranged on described PCB 10, each described light source 20 is covered with described lens 30.
In the utility model embodiment, described PCB 10 is laid with circuit, to realize specific function.As, described PCB 10 can be placed with several light sources 20, described light source 20 can be LED, and is equally spacedly arranged on described PCB 10, when described PCB 10 switches on power, can power, thus described light source 20 emits beam to described light source 20.
It should be noted that, in the utility model embodiment, described PCB 10 can arrange multiple light source 20, and different described light sources 20 can send the light of same color, also can send the light of different colours, the utility model does not do concrete restriction.
It should be noted that, in the utility model embodiment, it is simultaneously bright that described PCB 10 can control described light source 20; go out, the part that maybe can control in described light source 20 is gone out, and another part is bright simultaneously; these designs all, within protection domain of the present utility model, do not repeat them here.
In the utility model embodiment, because LED is lambert's type light source, thus need to utilize described lens 30 to carry out secondary optical design to the light that described light source 20 sends, to ensure light that described light source 20 sends spatially even.Wherein, described lens 30 can be refraction type lens, and it can be a concave mirror.Described lens 30 are located on described light source 20, the light that described light source 20 sends outgoing after the surface reflection or refraction of described lens 30.
In the utility model embodiment, in order to ensure that described lens 30 carry out suitable optical treatment to the light that described light source 20 sends, described lens 30 should keep fixing with the relative position of described light source 20, as described in light source 20 should be positioned at as described in the lens centre of lens 30.Particularly, described lens 30 comprise several fixing feet 32, and the madial wall of described lens 30 is fixed in one end of several described fixing feet 32, and the other end is fixed on described PCB 10.The other end of described fixing feet 32 and the distance of light source 20 are less than the distance of itself and rims of the lens, and wherein, described rims of the lens is the outline portion of the opening forming described lens.Described lens centre is that described lens 30 are when being positioned on described PCB 10, after the projection of the point described lens 30 with described PCB 10 with maximum height difference on described PCB 10 or described lens 30 project to the plane at described PCB10 place, the center of gravity of the geometry of formation.
It should be noted that, in the utility model embodiment, described PCB 10 offers several fixing hole (not shown), described fixing hole to offer position and interval each other corresponding with described fixing feet 32, namely, described fixing hole and described fixing feet 32 are one to one, when the other end of described fixing feet 32 is fixed on described PCB 10, this end of described fixing feet 32 is inserted in described fixing hole just, thus described fixing feet 32 is fixed on described PCB 10.
See also Fig. 3, particularly, the madial wall of described lens 30 is fixed in one end of described fixing feet 32, and the other end is vertically fixed on described PCB 10, to realize described lens 30 to be fixed on described PCB 10.Because described fixing feet 32 is between described lens centre and described rims of the lens, thus the distance between lens centre that the width of described PCB 10 is more than or equal to described lens 30 to described fixing feet 32 need only be ensured, can ensure that described lens 30 are fixed together with described PCB 10, and described lens 30 are relative fixing with the position of described light source 20.So, greatly can shorten the width of described PCB 10, thus save described PCB 10 material requested.Such as, suppose that described fixing feet 32 is positioned at the centre position of described lens centre and described rims of the lens, now, the width of described PCB 10 can be reduced to original half, namely saves a large amount of materials.
It should be noted that, in the utility model embodiment, the position of described fixing feet 32 can be arranged according to the actual needs, as when as described in lens centre to as described in the distance of rims of the lens be d time (taking lens centre as initial point), described fixing feet 32 can be arranged at d/4, d/3, d/2 or other optional positions, and the utility model is not specifically limited.
It should be noted that, in the utility model embodiment, described fixing feet 32 is arranged on described lens 30 by the mode of one-body molded design, and the number of fixing feet 32 that each described lens 30 have can be configured according to actual needs, 3 fixing feet 32 as configurable in each lens 30, and this 3 fixing feet 32 other end be fixed on described PCB 10 can form three summits of equilateral triangle, certainly, the number of the fixing feet 32 that each described lens 30 have also can be 1, 2, 4 or other quantity, in addition, the putting position of described fixing feet 32 also can be formed as triangle, rectangle or other arbitrary shapes, the utility model is all not specifically limited.
It should be noted that, in the utility model embodiment, during design, should guarantee that the fixed position of described fixing feet 32 does not affect the circuit trace of the attachment of described light source 20, lighting angle and described PCB 10.
In sum, the lamp bar 100 that the utility model embodiment provides, by the fixing feet 32 of described lens 30 is arranged between described lens centre and described rims of the lens, thus in the constitutionally stable situation of guarantee, reduce the width of described PCB 10, save the material of the PCB 10 produced needed for described lamp bar 100, reduce production cost.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly the interest field of the utility model can not be limited with this, one of ordinary skill in the art will appreciate that all or part of flow process realizing above-described embodiment, and according to the equivalent variations that the utility model claim is done, still belong to the scope that utility model contains.
