[0028] This utility model proposes an LED floodlight.
[0029] like Figure 1 As shown in one embodiment of this utility model, an LED floodlight includes an LED floodlight body, which includes a housing 1, LED beads 2, a heat sink 3, a driving power supply 4, a reflector 5, and an adjusting lens 6. The LED beads 2 are installed inside the housing 1. The heat sink 3 is fixedly connected to the end of the LED beads 2 away from the irradiation end. The irradiation end of the LED beads 2 is fixedly connected to the adjusting lens 6. The reflector 5 is sleeved on the adjusting lens 6. The driving power supply 4 is fixedly connected to the side of the heat sink 3 away from the LED beads 2. An adjusting device 7 for easy adjustment is also installed at one end of the housing 1.
[0030] Among them, the adjusting lens 6 is a semi-circular glass cover, which can concentrate light to a certain extent. Other materials or shapes can also be used to achieve this effect, which will not be described again. The adjusting device 7 can be a mechanical angle adjusting structure, which can achieve 0-180° angle adjustment through the cooperation of the rotating shaft positioning groove and the arc-shaped slide. The diameter of the positioning groove is smaller than the width of the slide to avoid movement jamming. It can also be a multi-hole positioning and pin structure, which sets multiple angle holes on the fixed seat and the adjusting seat. The positioning parts (such as pins) are inserted into different holes to fix the angle, and the rotating shaft assembly supports the rotating axis. The gear transmission angle adjusting structure can achieve continuous angle adjustment by rotating the planetary gear around the sun gear and driving the gear set through the adjusting handle. The elastic element assists in the reset. The bevel gear and rack transmission can drive the rack to move left and right through the angle adjusting shaft and drive the clamping parts to rotate synchronously to achieve the clamping angle adjustment.
[0031] In this embodiment, the LED beads 2 are directly mounted on the heat sink 3 to conduct heat from the light source substrate, thereby increasing the heat dissipation efficiency of the LED beads 2 and extending the service life of the LED beads 2. Furthermore, by installing an adjustment device 7 at one end of the outer casing 1, the installation angle of the LED floodlight body can be adjusted to achieve dynamic multi-scene adaptation.
[0032] Furthermore, the LED floodlight of this utility model includes an LED floodlight body and an adjustment device 7. The LED floodlight body consists of a shell 1, LED beads 2, a heat sink 3, an adjustment lens 6, a reflector 5, a driver power supply 4, a waterproof connector, and a breather valve. The shell 1 is made of die-cast aluminum alloy with an anodized surface and internal heat dissipation fins. The LED beads 2 are mounted on the surface of the heat sink 3 and electrically connected by gold wire bonding. The heat sink 3 is made of copper-aluminum composite material and is in close contact with the shell 1 through thermally conductive silicone grease. It has a finned structure on the back. The adjustment lens 6 is a Fresnel lens or a convex lens, which is fixed to the front end of the LED beads 2 by a snap-fit and can adjust the beam angle to 15°-120°. The reflector 5 is a parabolic aluminum coated reflector 5, nested on the outside of the adjustment lens 6 and connected to the shell 1 by threads. The driver power supply 4 is installed in the cavity on the back of the heat sink 3 and connected to the waterproof connector by a wire. The breather valve is located on the side of the shell 1101 and is made of GORE-TEX film material to balance the internal and external air pressure and prevent water vapor intrusion.
[0033] In high-temperature environments, the internal air expands and is discharged through the breather valve; in low-temperature environments, external air enters to prevent the outer casing 1 from deforming.
[0034] Preferably, such as Figure 2 As shown, the adjustment device 7 is one of a multi-dimensional adjustment device and a vertical adjustment device.
[0035] Furthermore, the multi-dimensional adjustment device 7 can achieve 360° horizontal rotation and ±90° pitch angle adjustment, suitable for scenarios requiring complex angle adjustments such as squares and stadiums. The vertical adjustment device 7 only supports ±90° tilt adjustment in the vertical direction and is fixed by a single-axis locking bolt, suitable for simple angle requirements such as road lighting.
[0036] Preferably, such as Figure 3 As shown, the multi-dimensional adjustment device includes an angle adjustment mechanism 71 and a height adjustment mechanism 72 rotatably connected to one end of the angle adjustment mechanism 71. The adjustment device 7 is provided with a support base 73. The angle adjustment mechanism 71 is rotatably connected to the support base 73, and the height adjustment mechanism 72 is fixedly connected to one end of the outer shell 1. The angle adjustment mechanism 71 can be horizontally rotated to adjust the angle, and the height adjustment mechanism 72 can be vertically rotated to adjust the angle. Through the cooperation of the two, the angle of the LED floodlight at various positions can be adjusted.
[0037] The angle adjustment device 7 includes a rotating disk 712 and a first motor. The rotating disk 712 is embedded in the bracket base 73 and rotates to connect with the bracket base 73. The output end of the first motor is fixedly connected to the center of the rotating disk 712. The height adjustment mechanism 72 includes a support bar and a second motor. The second motor is fixedly installed at one end of the support bar and rotates to connect with the LED floodlight body. The first motor is fixedly connected to the other end of the support bar.
[0038] Furthermore, the angle adjustment mechanism 71 includes a rotating frame 711 and a rotating disk 712. The rotating frame 711 is a U-shaped steel frame, and the rotating disk 712 is a toothed cast iron disk. The rotating disk 712 is embedded in the rotating groove 713 of the bracket base 73 and achieves smooth rotation through bearings. The height adjustment mechanism 72 is fixed to the LED floodlight body by bolts. The end of the rotating frame 711 is connected to the height adjustment mechanism 72 through a rotating shaft. The rotating shaft is equipped with a damping silicone ring to enhance friction resistance. The bottom of the bracket base 73 is provided with expansion bolt mounting holes, which can be fixed to the wall or column. The material is stainless steel 304 with a powder coating treatment.
[0039] Preferably, the angle adjustment mechanism 71 includes a rotating frame 711 and a rotating disk 712 fixedly connected to one end of the rotating frame 711. The end of the rotating frame 711 away from the rotating disk 712 is rotatably connected to the height adjustment mechanism 72. The support base 73 is provided with a rotating groove 713 that matches the rotating disk 712. The rotating disk 712 is embedded in the rotating groove 713 and rotatably connected to the support base 73. 360° rotation is achieved through the combination of the rotating disk 712 and the rotating groove 713.
[0040] Preferably, such as Figure 4 As shown, the bottom of the rotating disk 712 is provided with a first annular adjusting disk 714, and the bottom of the rotating groove 713 is provided with a second annular adjusting disk. The first annular adjusting disk 714 and the second annular adjusting disk are both composed of multiple evenly distributed retaining strips 715 facing the center of the adjusting disk. When the rotating disk 712 is embedded in the rotating groove 713, the retaining strips 715 of the first annular adjusting disk 714 and the second annular adjusting disk interlock with each other. The retaining strips 715 of the first annular adjusting disk 714 and the second annular adjusting disk are staggered. The retaining strips 715 generate a damping effect on the first annular adjusting disk 714 and the second annular adjusting disk, which facilitates the adjustment and fixation of the LED floodlight body.
[0041] Furthermore, the first annular adjusting plate 714 and the second annular adjusting plate each have 24 fan-shaped retaining strips 715, each retaining strip 715 being 2mm high and distributed at 15° intervals; the rotating plate 712 achieves positioning once every 15° rotation, and the engagement state is fixed by tightening the set screws on the side.
[0042] Preferably, the height adjustment mechanism 72 includes a third annular adjustment disk 721 vertically disposed on the LED floodlight body and a fourth annular adjustment disk 722 disposed at the end of the angle adjustment mechanism 71 away from the bracket base 73. Both the third annular adjustment disk 721 and the fourth annular adjustment disk 722 are composed of serrations evenly arranged along the periphery. The serrations of the third annular adjustment disk 721 and the fourth annular adjustment disk 722 are interlocked. The serrations exert a damping effect on the first annular adjustment disk 714 and the second annular adjustment disk, which facilitates the adjustment and fixation of the LED floodlight body.
[0043] Furthermore, the serrations of the third annular adjusting disc 721 and the fourth annular adjusting disc 722 are triangular teeth with a tooth depth of 3mm and a tooth pitch of 10°. When adjusting, lift the floodlight body, the serrations disengage and are adjusted to the required angle, and after being released, they automatically engage and lock with the fastener (wing nut).
[0044] Preferably, one end of the housing 1 is provided with a fastener for fixing the angle adjustment mechanism 71.
[0045] Furthermore, the fasteners are M8 stainless steel bolts that pass through the axial holes of the third and fourth annular adjustment discs 722 and are fitted with anti-loosening nuts at the ends to ensure that the meshing teeth do not dislodge under vibration.
[0046] Preferably, such as Figure 5 As shown, the up-down adjustment device is equipped with an adjustment frame 9, which is rotatably connected to the end of the LED floodlight body away from the illumination end.
[0047] Furthermore, the 9L-shaped steel plate of the adjustment frame has scale markings at the hinge point with the floodlight body, and the locking bolt is a thumb screw with a handle, which can be quickly tightened by hand.
[0048] Preferably, a light shield 8 is installed on one end of the reflector cup 5 of the outer casing 1.
[0049] One end of the sunshade is fixed to the outer shell 1 by bolts.
[0050] Furthermore, the light shield 8 is made of black PC plastic and is installed on the outside of the reflector cup 5 by means of clips or magnetic attraction. It can be cut into different lengths to meet the needs of beam control. Using a long light shield 8 can reduce stray light.
[0051] Specifically, the working principle and usage process of this utility model are as follows: by directly mounting the LED beads 2 on the heat sink 3, the heat on the light source substrate is conducted, increasing the heat dissipation efficiency of the LED beads 2 and extending the service life of the LED beads 2.
