Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 and 2, the LED floodlight of the present utility model includes a bracket and an LED module 1 mounted on the bracket, where the bracket and the LED module 1 are both in a bilateral symmetry structure. The bracket is of a U-shaped structure formed by a left side plate 2, a right side plate 3 and a mounting plate 4 connected between the left side plate 2 and the right side plate 3, the left side plate 2, the right side plate 3 and the mounting plate 4 are of an integrated structure formed by bending the same strip-shaped plate, and mounting holes 41 are formed in the mounting plate 4, so that the mounting plate can be fixed on the ground, the wall surface or a member of a building of an outdoor field through the mounting holes 41 when in use.
The upper ends of the left side plate 2 and the right side plate 3 are respectively provided with a left hanging plate and a right hanging plate 31 through connecting bolts 35, the left hanging plate and the right hanging plate 31 have the same structure and are bilaterally symmetrical, and the structure of the left hanging plate and the right hanging plate 31 is only described by taking the right hanging plate 31 as an example. The left hanging plate and the right hanging plate 31 are provided with strip-shaped hanging plate strips 32, a plurality of bolt holes 33 are formed in the hanging plate strips 32 along the length direction, and two sides of the LED module 1 are respectively installed in the bolt holes 33 of the left hanging plate and the right hanging plate 31 through module bolts. Each bolt hole 33 may be correspondingly provided with one LED module 1. In the embodiment of fig. 1 and 2, each hanging plate is provided with four bolt holes 33, so that at most four LED modules 1 can be installed, and 2 or 3 LED modules can be optionally installed according to the requirement. The light projection directions of the LED modules 1 corresponding to the bolts can be independently adjusted by loosening the bolts of a certain module, and different light projection directions can be set by different LED modules.
One side of the right hanging plate 31 is connected with a hanging plate strip 32 through an inclined folded plate 34, and the hanging plate strip 32 is parallel to the right hanging plate 31. The right hanging plate 31, the folded plate 34 and the hanging plate strip 32 are of an integrated structure formed by cutting and bending the same plate, the position of the hanging plate strip 32 is closer to the central symmetry line of the projection lamp relative to the right hanging plate 31 through the transitional connection of the folded plate 34, that is to say, the distance between the left hanging plate strip 32 and the right hanging plate 32 is slightly smaller than the distance between the left hanging plate and the right hanging plate 31, and the hanging plate strip 32 provided with the LED module 1 cannot touch the left side plate 2 or the right side plate 3 of the bracket when rotating.
As a further improvement of the present utility model, a plurality of positioning bolt holes 36 are provided around the connecting bolt 35 on the right hanging plate 31, and a positioning bolt 37 matching the positioning bolt holes 36 is mounted on the right side plate 3 by screw threads on one side of the connecting bolt 35. When the connecting bolt 35 and the positioning bolt 37 are loosened, the right hanging plate 31 can rotate on the right side plate 3, the inclination angles of the right hanging plate 31 and the hanging plate strip 32 are changed, and when the inclination angle of the hanging plate strip 32 is changed, all the LED modules 1 arranged on the hanging plate strip 32 can change the inclination angle along with the change of the inclination angle, which is equivalent to the change of the projection direction of the whole projection lamp. After the angle of the right hanging plate 31 is adjusted, the positioning bolt 37 is screwed down, so that the front end of the positioning bolt 37 is correspondingly inserted into one of the positioning bolt holes 36, and the positions of the right hanging plate 31 and the right side plate 3 can be locked.
The LED module 1 comprises a transparent panel 11 and a high heat conduction backboard 12 buckled on the back of the transparent panel 11 through a peripheral buckle, an LED substrate is arranged between the transparent panel 11 and the high heat conduction backboard 12, a heat dissipation convex rib 13 is arranged on the back of the high heat conduction backboard 12, and the module is connected to the heat dissipation convex rib 13 through bolts. The LED substrate is of a rectangular flat plate structure, a plurality of LED lamp beads are welded on the front face of the LED substrate, the transparent panel 11 is of a rectangular structure slightly larger than the LED substrate, the periphery of the transparent panel is provided with a folded edge which is bent backwards, and the folded edge is provided with a buckle for connecting the high-heat-conductivity backboard 12. The heat conducting backboard 12 is made of a material with high heat conductivity and insulation, and the front end of the heat conducting backboard is matched with the folded edge shape of the transparent panel 11 and is connected to the rear surface of the transparent panel 11 through a buckle. Such snap-on connection is a known technique and will not be described in detail herein. The heat radiation rib 13 includes a main rib of a rectangular ring-shaped structure and an auxiliary rib 14 provided on the outer circumferential surface of the main rib. The main rib of the rectangular annular structure has larger structural strength, and the module is not easy to deform when being connected to the heat dissipation convex rib 13 through bolts. The module bolts can be connected to the heat dissipation ribs 13 by hot melt welding or embedding, and can also be of an integrated structure.
In addition, in order to improve the heat dissipation efficiency and enhance the structural strength, the heat dissipation ribs 13 have a hollow structure, and metal heat dissipation fins connected to the LED substrate are embedded in the inner cavities of the heat dissipation ribs 13. The metal radiating fin has high heat conductivity and high structural strength, and the defects of low heat conductivity and insufficient strength of the high polymer material radiating ribs 13 can be overcome by embedding the radiating ribs 13.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
