Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-pole lamps, and more particularly to an LED high-pole lamp with adjustable illumination angle. BACKGROUND

[0002] With the acceleration of urbanization and the continuous improvement of infrastructure construction, high-pole lamps, as an important part of urban lighting, have increasing market demand. In particular, in some large public places such as stadiums and squares, high-pole lamps have become indispensable lighting equipment.

[0003] The illumination angle of the existing high-pole lamp LED lamp head is fixed and cannot be adjusted according to actual needs. This leads to less-than-ideal lighting effects in some application scenarios, such as overly concentrated light or insufficient illumination range, which cannot meet the lighting needs of specific areas. The existing high-pole lamp has limited lamp arm expansion range and cannot be flexibly adjusted according to the site and lighting needs. This limits the installation location and illumination range of the LED lamp head, affecting the lighting effect. In addition, the existing high-pole lamp lacks a detection mechanism for the installation stability of the lamp group unit. When the lamp group unit fails, it is often difficult to detect and maintain in a timely manner. This can lead to a decline in lighting effect and even cause safety hazards. SUMMARY

[0004] The present application aims to overcome the shortcomings of the prior art and provide an LED high-pole lamp with adjustable illumination angle.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: an LED high-pole lamp, comprising a lamp pole and a lamp holder installed on the lamp pole, the lamp holder comprising a circular cylindrical fixed cylinder fixedly connected with the lamp pole and two lamp group units installed on the fixed cylinder, the lamp group unit comprising a fixed lamp arm fixedly connected with the fixed cylinder, a fixed mounting plate fixed to the end of the fixed lamp arm, a first rotating ring installed on the fixed cylinder and capable of rotating relative to the fixed cylinder, a first L-shaped connecting block fixedly connected with the first rotating ring, a first rotating lamp arm fixedly connected with the first L-shaped connecting block, a first mounting plate fixed to the end of the first rotating lamp arm, a second rotating ring installed on the fixed cylinder and capable of rotating relative to the fixed cylinder, a second L-shaped connecting block fixedly connected with the second rotating ring, a second rotating lamp arm fixedly connected with the second L-shaped connecting block, a second mounting plate fixed to the end of the second rotating lamp arm, and an arc-shaped guide rod passing through the fixed lamp arm and fixedly connected with the fixed lamp arm, the first rotating lamp arm and the second rotating lamp arm each having an arc-shaped guide hole matched with the arc-shaped guide rod, and the fixed mounting plate, the first mounting plate, and the second mounting plate each having an LED lamp head installed thereon.

[0006] Furthermore, the LED lamp head includes a lamp head body, a protrusion fixedly connected to the lamp head body, and a first hinge seat connected to the lamp head body. The fixed mounting plate, the first mounting plate, and the second mounting plate each have a second hinge seat hinged to the first hinge seat. A first spring connects the fixed mounting plate, the first mounting plate, and the second mounting plate to their respective lamp head bodies. A first limiting plate is fixed to the first rotating lamp arm, and the first limiting plate has a first strip-shaped through groove. A second limiting plate is fixed to the second rotating lamp arm, and the second limiting plate has a second strip-shaped through groove. The LED high-mast lamp also includes a driving mechanism, which includes a vertical slide block with two through-holes for the fixed lamp arms. The vertical slide has a guide hole for limiting the position of the guide hole. U-shaped limiting rods are installed on both sides of the vertical slide. One U-shaped limiting rod passes through the first strip groove of the two lamp units, and the other U-shaped limiting rod passes through the second strip groove of the two lamp units. An electric telescopic rod is connected between the vertical slide and the fixed cylinder. Two sets of pull rope units are connected to the vertical slide. The pull rope unit includes a connecting pull rope, a first pull rope, and a second pull rope. The connecting pull rope is connected to the protrusion of the LED lamp head at the fixed lamp arm. The first pull rope is connected to the protrusion of the LED lamp head at the first rotating lamp arm. The second pull rope is connected to the protrusion of the LED lamp head at the second rotating lamp arm. The connecting pull rope, the first pull rope, and the second pull rope are all elastic pull ropes.

[0007] Furthermore, the connecting rope, the first rope, and the second rope are all in a stretched state.

[0008] Furthermore, the U-shaped limiting rod includes an upper horizontal rod, an upper arc-shaped rod connected to the upper horizontal rod, a vertical rod connected to the upper arc-shaped rod, a lower arc-shaped rod connected to the vertical rod, and a lower horizontal rod connected to the lower arc-shaped rod. The vertical rod of one of the U-shaped limiting rods passes through the first strip-shaped through slot of the two lamp units, and the vertical rod of the other U-shaped limiting rod passes through the second strip-shaped through slot of the two lamp units.

[0009] Furthermore, the fixed lamp arm, the first rotating lamp arm, and the second rotating lamp arm of the same lamp unit are at the same horizontal height.

[0010] Furthermore, the number of the electrically operated telescopic rods is one or two.

[0011] Furthermore, the LED high mast light also includes two clamping mechanisms, which correspond one-to-one with the two light assembly units. Each clamping mechanism includes a fixed rod fixedly connected to the fixed cylinder, a fixed plate fixedly connected to the fixed rod, a sliding plate that is passed through by the fixed rod and can slide relative to the fixed rod, a first clamping block fixedly connected to the sliding plate and capable of abutting against the first rotating ring, and a second clamping block fixedly connected to the sliding plate and capable of abutting against the second rotating ring. A second spring is connected between the sliding plate and the fixed plate.

[0012] After the lamp unit is installed, it is fixed by pressing against the first and second rotating rings.

[0013] Furthermore, the first rotating ring and the fixed cylinder are connected by a first bearing, and the second rotating ring and the fixed cylinder are connected by a second bearing.

[0014] This makes the first and second rotating rings rotate more smoothly.

[0015] In other embodiments, the fixed cylinder has a first annular groove and a second annular groove, a first annular slide rail that mates with the first annular groove at the first rotating ring, and a second annular slide rail that mates with the second annular groove at the second rotating ring.

[0016] Furthermore, the vertical slide has a third hinge seat, the fixed cylinder has a fourth hinge seat, one end of the electric telescopic rod is hinged to the third hinge seat, and the other end is hinged to the fourth hinge seat.

[0017] Furthermore, the fixed cylinder has multiple locking bolts, which are used to lock the relative positions of the fixed cylinder and the lamp post.

[0018] In some embodiments, the fixing cylinder is welded to the lamp post.

[0019] Furthermore, both the first rotating ring and the second rotating ring are circular rings.

[0020] Furthermore, the vertical slide has two fixing ring units, each including a pull rope fixing ring, a first fixing ring, and a second fixing ring. The pull rope fixing ring is connected to a connecting pull rope, the first fixing ring is connected to a first pull rope, and the second fixing ring is connected to a second pull rope. The pull rope fixing ring, the first fixing ring, and the second fixing ring are all semi-circular rings.

[0021] Furthermore, the protrusion has a pull cord through hole and a pull cord fixing bolt. The pull cord fixing bolt corresponding to the fixed lamp arm abuts against the connecting pull cord to fix the connecting pull cord and the protrusion. The pull cord fixing bolt corresponding to the first rotating lamp arm abuts against the first pull cord to fix the first pull cord and the protrusion. The pull cord fixing bolt corresponding to the second rotating lamp arm abuts against the second pull cord to fix the second pull cord and the protrusion.

[0022] The installation and adjustment of the pull rope are made more convenient by the addition of pull rope holes and pull rope fixing bolts.

[0023] Furthermore, the first pressing block has a first pressing arc surface, and a first anti-slip pad is installed on the first pressing arc surface; the second pressing block has a second pressing arc surface, and a second anti-slip pad is installed on the second pressing arc surface.

[0024] This achieves a better clamping effect, preventing the first and second rotating lamp arms from rotating unexpectedly.

[0025] Furthermore, one end of each of the two arc-shaped guide rods is connected to a first end connecting plate, and the other end is connected to a second end connecting plate.

[0026] This allows the two lamp units to be integrated, resulting in better installation stability.

[0027] Furthermore, the lamp assembly unit also includes a detection mechanism, which includes a first detection plate hinged to a vertical slide via a first elastic reset hinge component and a second detection plate hinged to a vertical slide via a second elastic reset hinge component. A first angle sensor is installed between the first detection plate and the vertical slide, and a second angle sensor is installed between the second detection plate and the vertical slide. The end of the first detection plate abuts against a first connecting rope, and the end of the second detection plate abuts against a second connecting rope.

[0028] This allows for the testing of the installation stability of the lamp unit.

[0029] Beneficial effects:

[0030] 1. The high-mast light of this application has an adjustable LED lamp head with adjustable illumination pitch angle, which can adjust the illumination range according to needs and improve the lighting effect.

[0031] 2. In the high-mast light of this application, the extension range of the first rotating lamp arm and the second rotating lamp arm can be adjusted. Both can be adjusted simultaneously by the drive mechanism, thereby adjusting the installation position of the LED lamp head.

[0032] 3. The high mast light of this application can detect the installation stability of the light unit, so that maintenance can be promptly reminded when a fault occurs, thus ensuring the stability of the high mast light. Attached Figure Description

[0045] Working Principle: The LED high-mast light of this application has multiple LED lamp heads, and the pitch angle of the LED lamp heads and the expansion angle of the first and second rotating lamp arms are adjustable, thereby achieving adjustment of the illumination range. Specifically, the vertical slide can be moved by an electric telescopic rod. As the vertical slide moves, the two U-shaped limiting rods also move. Due to the cooperation of the U-shaped limiting rods with the first and second strip grooves, the expansion angles of the first and second rotating lamp arms can be adjusted. When the vertical slide moves away from the lamp post, the expansion angles of the first and second rotating lamp arms decrease, and due to the shortening of the connecting ropes, the first rope, and the second rope, the tension decreases. As a result, under the action of the first spring, the front end of the LED lamp head rotates downward, thereby reducing the overall illumination range of the LED high-mast light. When the vertical slide moves towards the light pole, the expansion angle of the first and second rotating light arms increases, and the tension increases due to the extension of the connecting rope, the first rope and the second rope, causing the front end of the LED light head to rotate upward, thereby increasing the overall illumination range of the LED high pole light.

[0046] Furthermore, the first and second detection plates can abut against the first and second pull ropes. Under normal circumstances, the measured values ​​of the angle sensors corresponding to the four detection plates should be equal. When the measured values ​​of the four angle sensors are inconsistent, it indicates a fault, thus prompting timely maintenance. This allows the detection mechanism to test the installation stability of the lamp unit.

[0047] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
