Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 1 and accompanying drawing 6, a kind of efficiently reflective Fresnel LED zoom stage lighting of the present utility model, described LED stage lamp comprises aluminium base 1, LED light source 2, light-guiding pillar support 3, light-guiding pillar 4, lens 5, described LED light source 2 is fixedly mounted on aluminium base 1, described light-guiding pillar support 3 is made up of two parts, its top is square hollow cylinder, bottom is four legs, the junction of top and bottom is provided with oval table top, the centre that four legs link together is provided with the square hollow cylinder of leading fillet, this square hollow cylinder of leading fillet communicates with the square hollow cylinder on light-guiding pillar support 3 top, described light-guiding pillar 4 is square, be inserted in light-guiding pillar support 3 hollow cylinder, described light-guiding pillar 4 front end is provided with lens 5, described lens 5 one side is plane, another side is provided with ring shape striped projection 51, described ring shape striped projection 51 cross section is triangle, the inner surface of ring shape striped projection 51 slopes inwardly, its long inclined-plane is towards lens 5 center, outside by lens 5 center, the size of ring shape striped projection 51 increases gradually.Transparent material is triangular in shape, has very strong refraction effect, light can be launched fasciculation or divergent shape by the distance changed between light-guiding pillar 4 and lens 5.
Please refer to accompanying drawing 2 ~ 5, described light-guiding pillar 4 is the transparent body, its upper and lower two ends are square, light-guiding pillar 4 is reduce gradually from one end to the size of the other end, light-guiding pillar 4 inserts in light-guiding pillar support 3, its little square end end is at 1 ~ 2mm place, front of LED light source 2, the light that LED light source 2 sends is sent to the large square end of light-guiding pillar 4 by transparent light-guiding pillar 4, the square end end that light-guiding pillar 4 is large is provided with one piece of square catch 41, described catch 41 is provided with grid 42 on the surface, the grid cell of this grid 42 is square, light is dispersed to surrounding through grid, light after dispersing enters the planar ends of lens, lens make the light after dispersing be reflected (please refer to Fig. 7) by ring shape striped projection 51, light is made to form scattering or pencil, be radiated on object.
Please refer to accompanying drawing 7, the square hollow cylinder end on described light-guiding pillar support 3 top, is provided with the step mated with catch 41, and light-guiding pillar 4 inserts in light-guiding pillar support 3, and at light-guiding pillar support 3, place is blocked, and can be fixed, and avoids it to rock.
Four limit center lines of light-guiding pillar support 3 lower end square mouth part are provided with the radial line of four straight shapes, four radial lines only have 3 ~ 5mm length, its effect blocks fixing by the bottom of light-guiding pillar 4 square end, if do not arrange this radial line, light-guiding pillar 4 can be made to contact with the wall in light-guiding pillar support 3 bottom, one is too tight when light-guiding pillar 4 is inserted down, and two is to make light-guiding pillar 4 wall damage.Therefore, the generation that four radial lines can avoid problems is set.
Please refer to accompanying drawing 1, four, the lower end of light-guiding pillar support 3, leg end portions is provided with four positioning convex column, this positioning convex column is cylindrical, aluminium base 1 is also provided with the hole onesize with four positioning convex column, four positioning convex column are inserted in aluminium base 1 four holes, oval table top on light-guiding pillar support 3 is provided with two holes, and screw is inserted in two holes, by screw, light-guiding pillar support 3 is fixed with aluminium base 1.
Embodiment 1:
Please refer to accompanying drawing 7, in the drawings, lens 5 are away from light-guiding pillar 4, the light that LED light source 2 is launched is through over-light-transferring pole 4, by the grid 42 on light-guiding pillar 4, light scattering is being gone out, forming the larger scattered light of a radius, then the planar ends of light scioptics 5 again, at this moment, light generally can not reflect too much, when through ring shape striped projection 51, during due to ring shape striped projection 51, cross section is triangle, comparatively large to the refractive index of light, therefore, only penetrate from lens 5 after two road refractions, one rule directional light forms light beam, and degree of concentration is higher.
Embodiment 2:
Please refer to accompanying drawing 8, in the drawings, lens 5 are zero with the distance of light-guiding pillar 4, because do not have ring shape striped projection 51 at the middle part of lens 5, therefore, light also keeps original transmitting route when lens 5, launches in dispersion shape.
Stage lighting optical angle of the present utility model is little, degree of concentration is higher, on color blending effect, RGBW color blending effect is good, and enable stage lighting export more gorgeous effect of shadow, light from light source to light-guiding pillar out, light Jiao is formed under lens reflection, the focusing effect of high brightness can be reached, also can adjust the position of light-guiding pillar and lens, make light form beam emissions and go out; The utility model cost is lower, and zoom angle is large, and its zooming range is between 4-35 °.In addition, the hot spot cut-off property that the light that the utility model is launched is formed is good.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
