Description

Technical Field

[0001] This invention relates to the field of outdoor lighting technology, and more particularly to LED lighting lamps that allow for easy adjustment of the illumination angle and the illumination area. Background Technology

[0002] Outdoor lighting provides illumination to a specific area. The lamps inside these lamps are usually LED lamps. Currently, depending on the needs of the scene, some scenes require a lighting environment with good light concentration. To meet this requirement, spotlights are usually used for lighting. Spotlights have the characteristics of good light concentration, long illumination distance and a certain range of lighting radiation.

[0003] Currently, outdoor spotlights have some shortcomings in use: Spotlights are typically installed in a fixed position, lacking adjustable beam angle and illumination area. In other words, the beam angle and illumination area are inconvenient to adjust after installation, failing to meet real-time requirements such as continuously changing beam angles or illumination areas. Furthermore, while some spotlights on the market do offer adjustable beam angle and illumination area, these involve extensive transmission mechanisms. Due to the harsh outdoor environment (dust, oil stains), these transmission mechanisms are prone to jamming, resulting in poor practicality.

[0004] Therefore, this invention proposes an LED lighting lamp that allows for easy adjustment of the illumination angle and change of the illumination area. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] Please see Figure 1-9 This LED lighting fixture, which allows for easy adjustment of the illumination angle and area, includes a spotlight 1 and a lamp holder 2. The lamp head inside the spotlight 1 is an LED lamp, and the lamp holder 2 serves to support the spotlight 1. This LED lighting fixture is used for outdoor lighting. The adjustable illumination angle and area enable this lighting fixture to provide precise illumination, and it also has better dustproof and anti-pollution effects, making it suitable for long-term outdoor use.

[0040] In this technical solution, the lamp holder 2 includes a mounting ring 21 located at the bottom. During use, the mounting ring 21 is installed on an outdoor lamp post or wall. Specifically, a mounting plate 214 is fixedly connected to the outer peripheral wall of the mounting ring 21. The mounting plate 214 has mounting holes 2141 on its surface, which are bolt through holes. A positioning ring 3 is universally connected inside the mounting ring 21. Specifically, the inner peripheral wall of the mounting ring 21 has an inner spherical structure, and the outer peripheral wall of the positioning ring 3 has an outer spherical structure that matches the inner spherical surface. Therefore, the positioning ring 3 can swing universally under the cooperation of the inner and outer spherical surfaces.

[0041] The positioning ring 3 is fixedly connected to a coaxial connecting pipe 4 in the middle. When the connecting pipe 4 swings in all directions, it can drive the positioning ring 3 to swing in all directions. A connecting frame 5 is provided at the top of the connecting pipe 4. The connecting frame 5 and the connecting pipe 4 are rotatably connected, and the top of the connecting frame 5 is rotatably connected to the drive shaft 7 through the connecting frame 6. The lamp holder 2 includes a fixed seat 22 located above the mounting ring 21. The bottom of the fixed seat 22 is fixedly connected to the top wall of the mounting ring 21 through two arc-shaped rods. The drive shaft 7 is provided through the fixed seat 22 and is coaxial with the mounting ring 21. The drive shaft 7 and the fixed seat 22 are rotatably and slidably connected. In a specific implementation, it is preferred that a rotating sleeve 221 is sleeved through the fixed seat 22. The rotating sleeve 221 and the fixed seat 22 are rotatably connected. The rotating sleeve 221 is sleeved on the outside of the drive shaft 7 and the two are slidably connected. When the drive shaft 7 swings up and down, it can drive the connecting pipe 4 to swing through the connecting frame 2 6. When the positioning ring 3 and the mounting ring 21 are not on the same axis, when the drive shaft 7 is controlled to rotate, it can drive the connecting pipe 4, which is tilted relative to the vertical axis, to revolve around the axis of the drive shaft 7 through the connecting frame 2 6.

[0042] Among them, the top of the rotating sleeve 221 is fixedly fitted with a driven gear 2211, and the top wall of the fixed base 22 is fixedly connected with a motor 106, which is a small servo motor. The output shaft of the motor 106 is fixedly connected with a drive gear 1061 that meshes with the driven gear 2211. After the motor 106 starts, it can drive the rotating sleeve 221 to rotate under the meshing of the drive gear 1061 and the driven gear 2211. In turn, the rotating sleeve 221 can drive the drive shaft 7 to rotate. The top wall of the fixed base 22 is also fixedly connected with a motor 107, which is a small servo motor. The output shaft of the motor 107 is fixedly connected with a lead screw 1071, and a cantilever 1 is screwed onto the lead screw 1071. 10. The top of the cantilever 110 and the drive shaft 7 are rotatably connected. In specific implementation, one end of the cantilever 110 is fixedly connected to a threaded sleeve sleeved outside the lead screw 1071, and the bottom wall of the cantilever 110 is fixedly connected to an adapter sleeve near the other end and sleeved on the top of the drive shaft 7. The adapter sleeve and the drive shaft 7 are rotatably connected. When the motor 107 starts, it can drive the drive shaft 7 to move axially through the cantilever 110. In use, a controller (PLC) and a remote communication module are installed on the top wall of the fixed base 22. The controller is electrically connected to the remote communication module, the motor 107, and the motor 106. The operator can control the operation of the motor 106 and the motor 107 through the controller using a compatible wireless remote control. In use, a guide shaft is welded to the top wall of the fixed base 22, and a sleeve sleeved outside the guide shaft is welded to the cantilever 110. The sleeve and the guide shaft are slidably connected, which can improve the stability of the movement of the cantilever 110.

[0043] The mounting ring 21 contains several oscillating spotlights 1 arranged around the connecting pipe 4. There are at least three spotlights 1, and the more spotlights 1 there are, the better the illumination. A sliding sleeve 8 is fitted on the outside of the connecting pipe 4. The sliding sleeve 8 and the connecting pipe 4 slide together axially. The outer wall of the sliding sleeve 8 is connected to the outer shell of each spotlight 1 through a movable frame 9. When the sliding sleeve 8 moves back and forth along the axis of the connecting pipe 4, the spotlights 1 oscillate back and forth. Specifically, when the sliding sleeve 8 moves axially, it can drive all the spotlights 1 to swing inward and outward synchronously through the corresponding movable frame 9. When all the spotlights 1 swing inward and outward, the illumination area can be changed.

[0044] Furthermore, a support spring 109 is fitted onto the connecting pipe 4. The top of the support spring 109 abuts against the bottom of the sliding sleeve 8. When the sliding sleeve 8 moves downward, it can push the support spring 109 to compress. The connecting frame 5 is U-shaped and its bottom is fixedly connected to a connecting sleeve 51 fitted onto the outside of the connecting pipe 4. The connecting sleeve 51 and the connecting pipe 4 are rotatably connected. A portal rod 101 is slidably connected inside the connecting frame 5 along the axial direction of the connecting pipe 4. In specific implementation, clearance notches are opened on the two side walls of the connecting frame 5, and the crossbeam on the portal rod 101 1011 passes through the aforementioned clearance notch, and guide blocks are fixedly connected to both sides of the connecting frame 5. The guide blocks have sliding holes. The two vertical shafts on the portal rod 101 are fitted into the corresponding sliding holes. The vertical shafts and sliding holes are slidably connected. A roller 102 is provided at the bottom of the portal rod 101. A pad 81 with its upper end face abutting against the roller 102 is fixedly fitted at the top of the sliding sleeve 8. When the portal rod 101 moves up and down, it can push the pad 81 to move up and down. The setting of the roller 102 allows the portal rod 101 to rotate smoothly relative to the pad 81.

[0045] Furthermore, a positioning platform 211 is fixedly installed in the middle of the mounting ring 21 and fixedly connected to the bottom end of the connecting pipe 4. The top wall of the positioning platform 211 abuts against the bottom end of the support spring 109. A motor 103 is fixedly connected inside the positioning platform 211. In a specific implementation, a groove for accommodating the motor 103 can be opened in the bottom wall of the positioning platform 211. This groove communicates with the inner cavity of the connecting pipe 4. The output shaft of the motor 103 is fixedly connected to a lead screw 104 located inside the connecting pipe 4. The motor 103 is also a small servo motor and provides power to the rotation of the lead screw 104. The driving force is provided by a transmission sleeve 105 fitted on the top of the connecting pipe 4. The transmission sleeve 105 is fitted on the outside of the lead screw 104 and the two are screwed together. The lead screw 104 is in a hidden state. The transmission sleeve 105 has an internal thread that matches the lead screw 104. The transmission sleeve 105 and the connecting pipe 4 are axially slidably connected, and its top is rotatably connected to the crossbeam 1011 on the portal rod 101. When the lead screw 104 rotates, it can drive the transmission sleeve 105 to move axially, which in turn can drive the crossbeam 1011 to move up and down. When in use, the motor 103 and the controller are electrically connected.

[0046] In this embodiment, a detachable protective cover 222 is fitted over the outside of the fixed base 22. Specifically, the bottom of the protective cover 222 is open and screwed onto the outer peripheral wall of the fixed base 22. That is, the protective cover 222 can be separated from the fixed base 22 by rotating it. The function of the protective cover 222 is to isolate and protect the motor 206, motor 3107, controller, and remote communication module on the fixed base 22, preventing dust, oil, and other pollutants in the air from interfering with the structure inside the protective cover 222. The fixed base 22 has wiring holes.

[0047] Furthermore, the upper part of the lamp holder 2 is covered with a protective cover 108. The protective cover 108 has a hemispherical shell structure, which can shade the structure below and protect it from wind and rain. At the same time, it can greatly reduce the amount of dust accumulation and the speed of dust formation on the structure below the protective cover 108. The top of the protective cover 108 is fixedly connected to a mating sleeve 1081 that is sleeved on the outside of the protective cover 222. That is to say, the protective cover 108 can be removed together when the protective cover 222 is removed.

[0048] In this embodiment, the bottom end of the drive shaft 7 is fixedly connected to an eccentric shaft 72 via a connecting arm 71. That is, the eccentric shaft 72 is parallel to the drive shaft 7. The connecting frame 2 6 is an L-shaped frame structure. The bottom end of the eccentric shaft 72 is fixedly provided with a connecting sleeve 721. One end of the connecting frame 2 6 is fixedly provided with a short shaft 1 61, which is sleeved in the connecting sleeve 721 and the two are rotatably connected. The two sides of the other end of the connecting frame 2 6 are fixedly connected with the short shaft 2 62, which is rotatably connected to the two sides of the top of the connecting frame 1 5. The L-shaped frame structure of the connecting frame 2 6, the eccentric structure of the eccentric shaft 72, and the U-shaped structure of the connecting frame 1 5 enable the positioning ring 3 and the drive shaft 7 to be in a coaxial state. That is to say, in this state, the connecting frame 2 6 and the connecting frame 1 5 can give way to the drive shaft 7. When the tilt angle of the positioning ring 3 relative to the mounting ring 21 is fixed, the tilt angle of the positioning ring 3 will not change when the drive shaft 7 is rotated. Therefore, the illumination angle (the illumination direction can be changed arbitrarily) of the spotlight 1 relative to the horizontal plane will not change.

[0049] In this embodiment, a support frame 212 is fixedly connected between the outer peripheral wall of the positioning platform 211 and the inner peripheral wall of the positioning ring 3, and rotatably connected to the outer shell of the spotlight 1. One spotlight 1 corresponds to one support frame 212. In specific implementation, the support frame 212 includes a square frame and rod shafts fixedly arranged on both sides of the square frame. The outer peripheral wall of the positioning platform 211 is fixedly connected to one end of the corresponding rod shaft, and the inner peripheral wall of the positioning ring 3 is fixedly connected to one end of the corresponding rod shaft. Circular holes are opened on both sides of the square frame. The outer shell of the spotlight 1 is located inside the square frame. A support shaft located in the circular hole is fixedly connected to the outer peripheral wall of the outer shell. The support shaft and the circular hole are rotatably connected. The rotation plane of the spotlight 1 coincides with the radial line of the mounting ring 21. The movable frame 9 includes a U-shaped rod 91 and a lever 92. The non-open end of the U-shaped rod 91 is fixedly connected to the outer peripheral wall of the sliding sleeve 8. One end of the lever 92 is fixedly connected to the outer peripheral wall of the housing of the spotlight 1. A lever shaft 911 is fixedly connected to the open end of the U-shaped rod 91. The other end of the lever 92 is located inside the U-shaped rod 91 and has an oblong hole 921. The lever shaft 911 passes through the oblong hole 921. When the sliding sleeve 8 moves axially, it can drive the U-shaped rod 91 to move together. When the U-shaped rod 91 moves, it can push the lever 92 to swing through the cooperation of the lever shaft 911 and the oblong hole 921, thereby driving the spotlight 1 to swing.

[0050] Working principle: When in use, the mounting ring 21 is installed on the fixed mounting plate at the top of the outdoor light pole through the mounting plate 214 and the mounting hole 2141. After installation, ensure that the mounting ring 21 is in a horizontal state, and adjust the position of the spotlight 1 according to the illumination requirements of the site. When the illumination angle of this lighting fixture needs to be changed, the matching remote control is used to start motor 3 107, which drives lead screw 2 1071 to rotate. Lead screw 2 1071 drives cantilever 110 to move upward. When cantilever 110 moves upward, it drives drive shaft 7 to move upward. Drive shaft 7 drives connecting bracket 2 6 to move through eccentric shaft 72. When connecting bracket 2 6 moves, it pushes connecting bracket 1 5 to tilt. When connecting bracket 1 5 tilts, it drives connecting pipe 4 to tilt as well. At this time, positioning ring 3 will tilt relative to mounting ring 21. When positioning ring 3 tilts, it will drive all the spotlights 1 on it to tilt as a whole, changing the illumination angle of spotlight 1. When the illumination direction of spotlight 1 needs to be changed, control motor 2 106 to start, driving drive gear 1061 to rotate. When drive gear 1061 rotates, it drives rotating sleeve 221 to rotate through driven gear 2211. When rotating sleeve 221 rotates, it drives drive shaft 7 to rotate. When drive shaft 7 rotates, it drives connecting bracket 2 6 to revolve. When connecting bracket 2 6 revolve, it drives connecting pipe 4 to rotate. The connecting pipe 4 revolves, which in turn drives the spotlight 1 to illuminate at the same tilt angle through the positioning ring 3. When it is necessary to adjust the illumination area of ​​this LED lamp, the control motor 103 drives the lead screw 104 to rotate. The lead screw 104 drives the transmission sleeve 105 to move axially through the screwing action. When the transmission sleeve 105 moves axially, it can drive the gate rod 101 to move through the crossbeam 1011. The gate rod 101 pushes the pad 81 through the roller 102 to drive the sliding sleeve 8 to move axially evenly. When the sliding sleeve 8 moves axially, it can push the corresponding U-shaped rod 91 to move through the lever 92. The U-shaped rod 91 will push the outer shell to swing, which can drive the surrounding spotlight 1 to swing inward or outward synchronously. When the surrounding spotlight 1 swings outward synchronously, the illumination area of ​​this LED lighting lamp increases. When the surrounding spotlight 1 swings inward synchronously, the illumination area of ​​this LED lighting lamp decreases. When the illumination area decreases, the local light emitted by the surrounding spotlight 1 is in an overlapping state, which can improve the intensity of the illumination.
