Description
Technical Field
[0001] The utility model relates to the technical field of LED lighting, in particular to an LED floodlight. Background Art
[0002] Floodlights, also known as spotlights. Usually they can be aimed in any direction and have excellent three-proof structures. They are mainly used for decorative lighting in large-scale work sites, mines, building outlines, stadiums, overpasses, monuments, parks, flower beds and other outdoor places. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. New LED lamp beads have the advantages of high brightness, long life, no flicker, no heat radiation, etc., and have natural advantages in being used in floodlights. However, high-power LED lamp beads generate a lot of heat when working. In order to solve the heat dissipation problem, the commonly used means are usually to use fans to increase the airflow speed to achieve the purpose of active heat dissipation, or to use large-area heat sinks to achieve the purpose of passive heat dissipation. My other Chinese patent application 2022202172534 discloses "A floodlight fixture using a linear temperature control solution", including a shell, an LED substrate installed in the shell, a bracket installed on the shell, the shell includes a shell bottom plate, a side panel of an annular structure arranged around the shell bottom plate, a metal heat conductive sheet is attached to the inner wall of the shell bottom plate, the back of the LED substrate is tightly attached to the metal heat conductive sheet, and a panel is buckled on the shell, and a panel window for accommodating the LED substrate is provided on the panel, and the outer contour of the panel is connected to the edge of the side panel of the shell. The floodlight fixture uses composite heat dissipation materials to fit tightly and increase the contact area to improve the thermal conductivity efficiency, thereby achieving the purpose of improving the heat dissipation effect. However, this floodlight has a single structural form, and only one LED module can be installed on a bracket, and there can only be one projection direction, and the combination of LED modules cannot be flexibly adjusted according to actual needs.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figure 1 , Figure 2 As shown, the LED floodlight described in the utility model includes a bracket, an LED module 1 mounted on the bracket, and the bracket and the LED module 1 are both bilaterally symmetrical structures. The bracket is a U-shaped structure composed of 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 an integrated structure formed by bending the same strip plate; the mounting plate 4 is provided with a mounting hole 41, and when in use, it can be fixed to the ground, wall or building components of an outdoor venue through the mounting hole 41.
[0022] The upper ends of the left side plate 2 and the right side plate 3 are respectively mounted 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. Here, only the right hanging plate 31 is used as an example to describe its structure. The left hanging plate and the right hanging plate 31 are provided with a long hanging plate strip 32. The hanging plate strip 32 is provided with a plurality of bolt holes 33 along the length direction. The two sides of the LED module 1 are respectively mounted in the bolt holes 33 of the left hanging plate and the right hanging plate 31 through module bolts. Each bolt hole 33 can be corresponding to an LED module 1. Figure 1 , Figure 2In the embodiment, each hanging plate has four bolt holes 33, so a maximum of four LED modules 1 can be installed, and 2 or 3 LED modules can be installed as needed. By loosening a module bolt, the light projection direction of the LED module 1 corresponding to the bolt can be adjusted separately, and different LED modules can be set with different light projection directions.
[0023] One side of the right hanging plate 31 is connected to the hanging plate strip 32 through an inclined folding plate 34, and the hanging plate strip 32 is parallel to the right hanging plate 31. The right hanging plate 31, the folding plate 34 and the hanging plate strip 32 are an integrated structure formed by cutting and bending the same plate. The transition connection of the folding plate 34 makes the position of the hanging plate strip 32 closer to the central symmetry line of the floodlight relative to the right hanging plate 31, that is, the distance between the left and right hanging plate strips 32 is slightly smaller than the distance between the left hanging plate and the right hanging plate 31, and the hanging plate strip 32 with the LED module 1 installed will not touch the left side plate 2 or the right side plate 3 of the bracket when rotating.
[0024] As a further improvement of the present utility model, a plurality of positioning bolt holes 36 are arranged around the connecting bolt 35 on the right hanging plate 31, and a positioning bolt 37 matching the positioning bolt hole 36 is threadedly installed on one side of the connecting bolt 35 on the right side plate 3. By loosening the connecting bolt 35 and the positioning bolt 37, the right hanging plate 31 can be rotated on the right side plate 3 to change the inclination angle of the right hanging plate 31 and the hanging plate strip 32. When the inclination angle of the hanging plate strip 32 changes, all LED modules 1 installed on the hanging plate strip 32 will change the inclination angle accordingly, which is equivalent to changing the projection direction of the entire floodlight. After adjusting the angle of the right hanging plate 31, tighten the positioning bolt 37 so that the front end of the positioning bolt 37 is correspondingly inserted into one of the positioning bolt holes 36, and the position of the right hanging plate 31 and the right side plate 3 can be locked.
[0025] The LED module 1 includes a transparent panel 11, a high thermal conductivity back plate 12 that is 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 thermal conductivity back plate 12, and a heat dissipation rib 13 is arranged on the back of the high thermal conductivity back plate 12, and the module is bolted to the heat dissipation rib 13. The LED substrate is a rectangular flat plate structure, and a plurality of LED lamp beads are welded on its front side. The transparent panel 11 is a rectangular structure slightly larger than the LED substrate, and has a folded edge that is bent backward around it, and there are buckles on the folded edge for connecting the high thermal conductivity back plate 12. The thermal conductive back plate 12 is made of a material with high thermal conductivity and insulation, and its front end matches the folded edge shape of the transparent panel 11, and is connected to the back of the matching transparent panel 11 through a buckle. This buckle-type connection structure is a well-known technology and will not be described in detail here. The heat dissipation rib 13 includes a main rib of a rectangular ring structure and an auxiliary rib 14 arranged on the outer peripheral surface of the main rib. The main rib of the rectangular ring structure has a greater structural strength, and the module bolts are not easily deformed when connected to the heat dissipation ribs 13. The module bolts can be connected to the heat dissipation ribs 13 by hot-melt welding or embedding, or an integrated structure can be used.
[0026] In addition, in order to improve the heat dissipation efficiency and enhance the structural strength, the heat dissipation rib 13 is a hollow structure, and a metal heat sink connected to the LED substrate is embedded in the inner cavity of the heat dissipation rib 13. The metal heat sink has a high thermal conductivity and a high structural strength. Embedding it in the heat dissipation rib 13 can make up for the defects of low thermal conductivity and insufficient strength of the heat dissipation rib 13 made of polymer material.
[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
