The anti-dazzle stadium projection lamp shown in fig. 1-5 comprises a strip-shaped mounting plate 1, wherein the lamp body 2 is connected below the mounting plate 1 through power wires 102, the power wires 102 not only play a role in supplying power to the lamp body 2, but also play a role in providing upward lifting force to the lamp body 2, in the embodiment, two equal-length power wires 102 are connected below the mounting plate 1, namely, the lengths of the parts of the power wires 102 between the mounting plate 1 and the lamp body 2 are equal, the lengths of the two power wires 102 which are completely stretched out from a wiring cap 202 are also equal, the top of a shell 201 is also provided with the wiring caps 202, the number of the wiring caps 202 is also two, the wiring caps are symmetrically distributed in a left-right manner and are respectively close to two ends of the shell 201, the weight balance of the left-right is ensured, the lower ends of the two power wires 102 are respectively connected with the two wiring caps 202, a winding mechanism is usually arranged in the wiring cap 202 for realizing winding and unwinding of the power wires 102, the winding mechanism is driven by a motor, and the soft and tensile power line 102 is wound or released through the winding disc, so that the power line 102 needs to pass through the wiring cap 202 and is in sliding contact with the wiring cap 202, in order to ensure that the power line 102 can be completely wound into the wiring cap 202, the two power lines 102 are vertical, that is, the upper end of the power line 102 connected with the mounting plate 1 is right above the wiring cap 202, the power line 102 can be wound in the wiring cap 202 by the winding mechanism, and when the wiring cap 202 contacts the mounting plate 1, the power line 102 is completely wound, the mounting plate 1 is provided with a connecting hole 101 penetrating through the upper surface and the lower surface between the two power lines 102 for a connecting piece such as a bolt to pass through, the mounting plate 1 is fixed on a frame structure at the top of the stadium, and the frame structure is not horizontal at any time, so can let lamp body 2 keep the level through the extension length of two power cords 102, of course, lamp body 2 is not in the horizontality and also can provide the illumination, just to the stadium ground that is far away, the lamp body 2 of horizontality can produce more even light distribution effect, so under the general circumstances mounting panel 1 can be fixed on stadium top horizontally mounting bracket body, like this direct control power cord 102 length the same can, in this embodiment, connecting hole 101 has a plurality of, a plurality of connecting hole 101 divide into left and right sides two sets, equidistant arranging between the connecting hole 101 in every group for dispose more bolts, guarantee the stability of installation, because if directly use one or two bolts, single bolt will bear great stress effect, use for a long time, the probability that the fracture dropped can be great, increase the quantity of connecting piece just in order to reduce the lamp because the probability that drops because of hanging the use for a long time, prolong the maintenance cycle, reduce the cost of labor of maintaining.

The specific structure of lamp body 2 includes same rectangular casing 201, casing 201 generally adopts corrosion-resistant alloy material to support, compromise higher thermal conductivity, come to satisfy self-heating radiating demand, in order to improve the radiating efficiency of projecting lamp, still can design top heat dissipation muscle 203 at the top of casing 201, top heat dissipation muscle 203 extends along the length direction of casing 201, but the length is less than casing 201, like conventional heat dissipation muscle structure, the quantity of top heat dissipation muscle 203 has a plurality of, all with casing 201 integrated into one piece, equidistant arrangement between a plurality of top heat dissipation muscle 203, the clearance between allows the air current to pass through, therefore fine heat convection air cooling effect has, top heat dissipation muscle 203 all is located between two terminal caps 202, terminal cap 202 then can with the casing 201 split, side heat dissipation groove 204 has been seted up to the side of casing 201, further increase the heat dispersion of casing 201.

The bottom surface of casing 201 begins to have the sunken reflection of light recess 206 of upwards, the lower extreme of reflection of light recess 206 is big, the upper end is little, scribble the silver layer in the reflection of light recess 206, have fine reflectivity, and the thermal conductivity is also better in addition, can give casing 201 heat dissipation fast, the interior top surface of reflection of light recess 206 is provided with LED lamp pearl 207, as main luminous element, equally have a plurality of, the equidistance is arranged at the interior top surface of reflection of light recess 206, casing 201 is in the fixed connection of the position near the bottom and disposes frame 205, the cross-sectional area of disposition frame 205 is obviously bigger than the bottom surface of casing 201, the disposition frame 205 internal fixation has the diffuser plate 208 that shelters from the open end under the reflection of light recess 206, therefore diffuser plate 208 also can keep away the biggest tip of reflection of light recess 206, diffuser plate 208 adopts the acrylic plate of frosted, have high haze, high transmittance, high diffusivity, the dazzling problem of lamp has been effectively avoided.

Working principle: this projecting lamp can use connecting piece installation such as bolt on the horizontal stand at stadium top or the sloping frame, and the winding mechanism of accessible terminal cap 202 adjusts the extension length of power cord 102 after the installation to change the difference in height at lamp body 2 both ends, let lamp body 2 keep horizontal optimum to the ground projecting state, the illumination that LED lamp pearl 207 produced is diffused by the diffuser plate 208 that the area is bigger, and the illumination is softer, not dazzling.

The foregoing has outlined the basic principles, features, and advantages of the present application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present application, and various changes and modifications may be made therein without departing from the spirit and scope of the application, which is defined by the appended claims.
