Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of LED lighting, and in particular to an LED floodlight. Background Art

[0002] When using LED floodlights, due to different requirements for the light-emitting angle and direction, the existing structure of adjusting the illumination angle of LED floodlights is to directly connect the bottom shell of the LED floodlight to the fixed bracket through bolts. When adjusting the illumination angle, you need to loosen the bolts first, rotate the LED floodlight to get the desired illumination angle, and then tighten the screws again to complete the fixation. The LED floodlight is fixed at the determined angle by the friction resistance between the bolts and the bottom shell. When the number of adjustments increases, the contact surface between the bolts and the floodlight is prone to excessive wear, resulting in insufficient friction resistance and looseness. Moreover, if the LED floodlight is heavy, it is also difficult to effectively fix the LED floodlight at the determined angle only by the friction resistance between the bolts and the bottom shell. Summary of the invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide an LED floodlight that can conveniently adjust and fix the irradiation angle.

[0004] In order to solve the above technical problems, an embodiment of the present invention first provides the following technical solutions: an LED floodlight, comprising an LED lamp body and a mounting bracket connected to the LED lamp body and used to be fixed to a corresponding fixture, the mounting bracket comprising a fixing bracket used to be fixed to the corresponding fixture, a movable bracket having one end fixed to the LED lamp body and the other end pivotally connected to the fixing bracket, the fixing bracket and the movable bracket are respectively provided with a first axial hole and a second axial hole, and a bolt passes through the first axial hole and the second axial hole and is screwed with a nut to cause the fixing bracket to abut against the movable bracket, a side of the fixing bracket abutting against the movable bracket is provided with a plurality of first dividing structures uniformly distributed radially relative to the first axial hole, and a side of the movable bracket abutting against the fixing bracket is correspondingly provided with a plurality of second dividing structures uniformly distributed radially relative to the second axial hole, when the fixing bracket abuts against the movable bracket, the first dividing structures and the second dividing structures respectively provided on the fixing bracket and the movable bracket are concave-convex matched and engaged.

[0005] Further, the first graduation structure is a graduation convex strip, and the second graduation structure is a graduation groove; or, the first graduation structure is a graduation groove, and the second graduation structure is a graduation convex strip.

[0006] Furthermore, the LED lamp body includes a long strip-shaped bottom shell made of profiles and an LED light-emitting module assembled in the bottom shell.

[0007] Furthermore, the outer surfaces of the opposite side walls of the bottom shell are also formed with a shrinkage groove that penetrates the bottom shell along the length direction, and the opposite sides of the movable frame are also formed with corresponding protrusions. The ends of the connecting arms form sliding parts with cross-sectional shapes and sizes that are compatible with the cross-sectional shapes and sizes of the inner cavity of the shrinkage groove, and the thickness of the part of the connecting arm corresponding to the notch of the shrinkage groove is smaller than the width of the notch. The movable frame is slidably connected to the shrinkage groove with the sliding parts at the ends of the connecting arms on both sides and fits with the inner wall of the shrinkage groove.

[0008] Furthermore, the inner cavity of the shrinkage groove is a through hole with a circular cross section, and the sliding part of the connecting arm is a cylinder connected to the main part of the connecting arm at the side.

[0009] Furthermore, a first screw hole is formed on the connecting arm, and a screw is screwed into the first screw hole and the inner end surface is pressed against the outer side surface of the corresponding side wall of the bottom shell to fix the movable frame on the bottom shell.

[0010] Furthermore, a through hole is formed on the connecting arm, and a second screw hole is formed on the bottom shell correspondingly. Another screw passes through the through hole on the movable frame and is screwed into the second screw hole on the bottom shell to fix the movable frame on the bottom shell.

[0011] Furthermore, the LED light emitting module is a plurality of LED point light source modules connected in series and installed along the length direction of the bottom shell.

[0012] Furthermore, there are at least two mounting brackets, which are respectively assembled at predetermined positions of the bottom shell.

[0013] Furthermore, an elastic washer is sleeved between the tail of the bolt and the nut.

[0014] After adopting the above technical scheme, the embodiment of the present invention has at least the following beneficial effects: the mounting bracket of the embodiment of the present invention adopts a split structure of a fixed frame and a movable frame, which is easy to install, and the first dividing structure and the second dividing structure are respectively arranged around the first axial hole and the second axial hole of the fixed frame and the movable frame, and the positioning of the fixed frame and the movable frame is achieved by the mutual abutment and engagement of the first dividing structure and the second dividing structure, thereby avoiding the phenomenon that the illumination angle of the floodlight cannot be fixed due to wear of the contact surface between the fixed frame and the movable frame after long-term use, and the illumination angle of the floodlight can be effectively fixed. Moreover, when it is necessary to adjust the illumination angle of the LED lamp body, it is only necessary to loosen the bolts to disengage the first dividing structure and the second dividing structure, and the LED lamp body can be conveniently adjusted to the desired illumination angle, and then the bolts can be retightened to engage the first dividing structure and the second dividing structure again, so that the illumination angle can be conveniently adjusted and fixed.

Moreover, when it is necessary to adjust the illumination angle of the LED lamp body 1, it is only necessary to loosen the bolt 7 to disengage the first dividing structure 503 and the second dividing structure 523, and the LED lamp body 1 can be conveniently adjusted to the desired illumination angle, and then the bolt 7 can be re-tightened to make the first dividing structure 503 and the second dividing structure 523 engage again, so that the illumination angle can be conveniently adjusted and fixed.

[0021] In an optional embodiment of the present invention, the first graduation structure 501 is a graduation ridge, and the second graduation structure 503 is a graduation groove; or, the first graduation structure 501 is a graduation groove, and the second graduation structure 503 is a graduation ridge. In this embodiment, one of the first graduation structure 501 and the second graduation structure 503 uses a graduation groove and the other uses a graduation ridge, both of which can effectively fix the LED lamp body 1 at the desired illumination angle. Figure 1-Figure 3 In the embodiment, the first dividing structure 501 and the second dividing structure 503 respectively adopt dividing ridges and dividing grooves.

[0022] In an optional embodiment of the present invention, the LED lamp body 1 includes a bottom shell 10 in a long strip shape made of a profile and an LED light-emitting module 12 assembled in the bottom shell 10. In this embodiment, the LED lamp body 1 directly uses the profile to make the bottom shell to assemble the LED light-emitting module 12. The cross-sectional shape of the profile is highly designable, which is convenient for designing a lamp with a suitable shape, and the structural dimensional accuracy of the profile is guaranteed, which is convenient for assembly.

[0023] In an optional embodiment of the present invention, the outer surfaces of the opposite side walls of the bottom shell 10 are also formed with a necking groove 101 that penetrates the bottom shell 10 along the length direction, and the opposite sides of the movable frame 52 are also respectively protruded with connecting arms 525, and the ends of the connecting arms 523 form sliding portions 5250 whose cross-sectional shape and size are adapted to the cross-sectional shape and size of the inner cavity of the necking groove 101, and the thickness of the portion of the connecting arm 525 corresponding to the notch of the necking groove 101 is less than the width of the notch, and the movable frame 52 is slidably connected to the necking groove 101 with the sliding portions 5250 at the ends of the connecting arms 525 on both sides and fits with the inner wall of the necking groove 101. In this embodiment, the sliding portion 5250 at the end of the connecting arm 525 cooperates with the shrinkage groove 101 on the bottom shell 10, so that the relative position between the movable frame 72 and the bottom shell 10 can be adjusted arbitrarily according to the specific length of the bottom shell 10. In addition, during the specific assembly, the sliding portion 5250 of the connecting arm 525 can be directly slid into the shrinkage groove 101 from one end of the bottom shell 10, which is very convenient. In addition, the thickness of the portion of the connecting arm 525 corresponding to the notch of the shrinkage groove 101 is made smaller than the width of the notch to prevent the connecting arm 525 from falling out of the notch position of the shrinkage groove 101.

[0024] In an optional embodiment of the present invention, the inner cavity of the necking groove 101 is a through hole with a circular cross section, and the sliding portion 5250 of the connecting arm 525 is a cylinder connected to the main part of the connecting arm 525 at the side. In this embodiment, the necking groove 101 and the sliding portion 5250 are respectively a through hole with a circular cross section and a cylinder, which has a simple structure and facilitates the sliding of the connecting arm 525 in the necking groove 101.

[0025] In an optional embodiment of the present invention, a first screw hole 5252 is further provided on the connecting arm 525, and a screw 5254 is screwed into the first screw hole 5252 and the inner end surface is tightly pressed against the outer side surface of the corresponding side wall of the bottom shell 10 to fix the movable frame 52 to the bottom shell 1. In this embodiment, the screw 5254 is screwed into the first screw hole 5252 and the inner end surface is tightly pressed against the corresponding side wall of the bottom shell 10. During the specific assembly, it is only necessary to loosen the screw 5254 and the screw 5254 is disengaged from the bottom shell 10 to adjust the position of the movable frame 52 without completely screwing out the screw 5254, thereby improving the assembly efficiency.

[0026] In an optional embodiment of the present invention, a through hole 5256 is further provided on the connecting arm 525, and a second screw hole 103 is correspondingly provided on the bottom shell 10, and a screw 5254 passes through the through hole 5256 on the movable frame 52 and is screwed into the second screw hole 103 on the bottom shell 10 to fix the movable frame 52 on the bottom shell 10. In this embodiment, the screw 105 passes through the through hole 5256 on the movable frame 52 and is screwed into the second screw hole 103 on the bottom shell 10, and after the movable frame 52 slides into place, the movable frame 52 can be effectively locked to prevent sliding.

[0027] In an optional embodiment of the present invention, the LED light emitting module 12 is a plurality of series-connected LED point light source modules 121 installed along the length direction of the bottom shell 10. In this embodiment, the LED light emitting module 12 uses a plurality of series-connected LED point light source modules 121, so that the light emitting surface of the entire bottom shell 10 can evenly radiate light, and the irradiation efficiency is higher.

[0028] In an optional embodiment of the present invention, there are at least two mounting brackets 5, which are respectively assembled at predetermined positions of the bottom shell 1. In this embodiment, mounting brackets 5 are arranged at predetermined positions at opposite ends of the bottom shell 10, so that the LED lamp body 1 has stronger stability after installation and fixation, and it is more convenient to adjust the irradiation angle of the LED floodlight. Figure 1 In the embodiment, one of the two mounting brackets 5 is screwed into the second screw hole 103 on the bottom shell 10 by a screw 5254 for fixing, and the other is screwed into the first screw hole 5252 on the connecting arm 525 by a screw 5254. When specifically adjusting the position of the movable frame 52, it is only necessary to screw the screw 5254 screwed into the first screw hole 5252 on the connecting arm 525 to adjust one of the movable frames 52.

[0029] In an optional embodiment of the present invention, an elastic washer 72 is sleeved between the tail of the bolt 7 and the nut 70. In this embodiment, by sleeved with the elastic washer 72 on the bolt 7, the locking stability of the bolt 7 is effectively improved, ensuring that the lighting angle of the LED floodlight will not change easily.
