The beneficial effects of the utility model are: because the utility model adopts the structure of setting conductive plate in the bar shaped guide rail, so its structure need be provided with chute than prior art in housing and in chute the structure of placement lead more small and exquisite, compactness; Positioning seat is worn and is hung on the guide rail, be provided with respectively two contacts that electrically contact with two conductive plates in it, two contacts in LED shot-light and the positioning seat are electrically connected, and be connected with positioning seat by universal joint, like this, its connecting structure for electrical equipment is fairly simple, and positioning seat can be adjusted along the rail length direction, and the LED shot-light can be reconciled projecting direction at stereo directional.

In addition, the utility model can also be further improved by the following technical programs:

The size of the vertical direction of described guide rail is bigger than the size of horizontal direction, like this, under the long-pending situation of same cross-sectional, stressed bigger on the track vertical direction.

Described two conductive plates are arranged on the two sides of guide rail vertical direction, and like this, the insulation safety factor is higher.

Described two conductive plates are symmetricly set on the two sides of guide rail vertical direction, like this, the guide rail structure symmetry, force-bearing situation is better.

Described two conductive plates shift to install up and down in the two sides of guide rail vertical direction, and like this, the force-bearing situation on the guide rail vertical direction is better.

Described positioning seat comprises semicircular cylinder and the block that two lobes are detachable, and guide rail passes between two semicircular cylinders, and it is fairly simple that such positioning seat is installed manufacturing.

Described contact is for being washed off into band convex and dull and stereotyped structure by sheet metal, two contacts are installed in respectively in two semicircular cylinders, and its flat board is fixed on the semicircular cylinder inwall, and two convexes correspondence is inwardly outstanding to electrically contact with conductive plate.

In addition, reliable for guaranteeing electrically contacting of contact and conductive plate, also can be provided with spring at the reverse side that described convex contacts with conductive plate convex is compressed to conductive plate.

The specific embodiment

Embodiment 1, and with reference to figure 2, Fig. 3, Fig. 4 and Fig. 5, a kind of New LED track lamp comprises a strip guide rail 1, made by insulating materials, is used to provide mobile guide; Two conductive plates 11 are embedded in described guide rail 1 surface respectively, along the length direction extension of guide rail; Positioning seat 2 is worn and is hung on the guide rail 1, is provided with respectively two contacts 7 that electrically contact with two conductive plates 11 in it; LED shot-light 4 is electrically connected with two contacts 7 in the positioning seat 2, and is connected with positioning seat 2 by universal joint 3.

With reference to figure 3 and Fig. 7, the vertical direction size of guide rail 1 is bigger than horizontal direction size, like this, under the long-pending situation of same cross-sectional, stressed bigger on guide rail 1 vertical direction, guide rail 1 both sides are symmetrically arranged with fore shaft groove 12 along the length direction of guide rail 1, and its shape of cross section can be rectangle, circle or the polygon that a side has opening, and described conductive plate 11 promptly is embedded in this fore shaft groove 12; Conductive plate 11 is thin slices of being made by conductive material, and its shape needs corresponding with fore shaft groove 12; With reference to figure 3, Fig. 4 and Fig. 5, positioning seat 2 is a hollow-core construction, comprise two detachable semicircular cylinder 21 and blocks 22, like this, can reduce the use of material on the one hand, weight reduction, the lead (not shown) that one contact 7 and electrical connection contact 7 and LED shot-light 4 can respectively be set in two semicircular cylinders 21 on the other hand makes that product integral body is compacter, after two semicircular cylinders 21 clamped on the guide rail 1, block 22 screwed in from two semicircular cylinders, 21 tops, guaranteed that positioning seat 2 can hang on the guide rail 1 in firm wearing; With reference to figure 6, contact 7 is for being washed off into the structure of band convex 71 and dull and stereotyped 72 by sheet metal, two contacts 7 are installed in respectively in two semicircular cylinders 21, its flat board 72 usefulness screws are fixed on semicircular cylinder 21 inwalls, two convexes 71 are corresponding inwardly outstandingly to electrically contact with the conductive plate 11 of guide rail 1 both sides respectively, certainly, also can be provided with spring 8 at the reverse side that described convex 71 contacts with conductive plate 11, convex 71 is compressed to conductive plate 11, to increase the pressure of contact convex 51 and conductive plate 11, strengthen the reliability that both electrically contact; Described universal joint 3 promptly is to include the secondary kinematic pair, and the member that can allow joint two ends joint in relative rotation in orthogonal two planes also is hollow structure in it, so just can pass the lead that connects contact 7 and LED shot-light 4; Described LED shot-light 4 can adopt any a shot-light with optically focused effect of prior art, its structure generally comprises housing, be installed in the reflector in the housing and be installed in the interior LED lamp of reflector, it is relatively simple for structure, and with common shot-light structural similarity in the prior art, so do not give unnecessary details at this.

Embodiment 2, with reference to figure 8, its structure is similar to embodiment 1, difference is: described fore shaft groove 12 is dislocatedly distributed up and down in guide rail 1 both sides, can increase the ratio of guide rail 1 vertical direction size and lateral dimension like this, make that guide rail has better rigidity at vertical direction under identical sectional area situation, can hold and hang more LED shot-light.

Among above-described two embodiment, described guide rail 1 can be a rigid material with the conductive plate 11 that is embedded in the guide rail 1, also can make guide rail 1 to adapt to the needs of light design space towards lateral thrust with the material manufacturing that certain flexibility is arranged.
