Description

Technical Field

[0001] The present invention relates to the technical field of solar street lamps, and particularly to a solar street lamp with photovoltaic energy saving and environmental protection. Background Art

[0002] A street lamp refers to a lamp that provides lighting for roads, generally referring to the lamps within the range of road surface lighting in traffic lighting. Street lamps are widely used in various places that require lighting. A street lamp consists of a lamp, wires, a light source, a lamp post, a lamp arm, a flange plate, and a foundation embedded part as a whole. Street lamps can be divided into public power lighting street lamps and solar street lamps according to different energy sources used; A solar street lamp uses a crystalline silicon solar cell for power supply, a maintenance-free valve-regulated sealed battery (gel battery) to store electrical energy, a super-bright LED lamp as the light source, and is controlled by an intelligent charge and discharge controller, and is used to replace traditional public power lighting street lamps.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] As Figure 1 shown, a solar street lamp with photovoltaic energy conservation and environmental protection includes a lamp post 1. A photovoltaic panel fixing bracket 4 is detachably installed at the top end of the lamp post 1. A solar photovoltaic panel 8 is detachably fixed on the upper surface of the photovoltaic panel fixing bracket 4. A lamp fixture fixing bracket 2 is fixed on the outer side of the top end of the lamp post 1. The bottom of one end of the lamp fixture fixing bracket 2 is fixed with a lamp fixture fixing plate 3. A lamp shade 7 is detachably installed on the bottom surface of the lamp fixture fixing plate 3.

[0020] As Figure 2 and Figure 3 shown, a plurality of linearly arranged air intakes 9 are respectively provided through both ends of the lamp shade 7. A heat absorption and heat dissipation tube 5 is installed between every two air intakes 9 with coincident axes. The heat absorption and heat dissipation tube 5 is a hollow pipe. The axis of the heat absorption and heat dissipation tube 5 is parallel to the reduced configuration groove 606. A plurality of spiral drainage strips are fixed inside the heat absorption and heat dissipation tube 5. The drainage strips are distributed in a circular array around the axis of the heat absorption and heat dissipation tube 5. The width dimension of the drainage strip is half of the radius of the heat absorption and heat dissipation tube 5. The existence of the reduced configuration groove 606 on the surface of the adjusting plate 601 enables the heat generated during the operation of the split lighting strip 605 to move upward. The heat is absorbed by the heat absorption and heat dissipation tube 5. At the same time, an external low-temperature air flow flows through the hollow heat absorption and heat dissipation tube 5. When the air flow flows, the heat absorbed by the heat absorption and heat dissipation tube 5 is dissipated, realizing the heat dissipation during the operation of the street lamp and avoiding the failure of the street lamp due to overheating.

[0021] As shown Figures 3 to 5 in the figure, an energy-saving lighting structure 6 is installed between the lamp shade 7 and the lamp fixture fixing plate 3, and the energy-saving lighting structure 6 is fixed inside the lamp shade 7. The energy-saving lighting structure 6 includes a fixing plate 604. The four sides of the fixing plate 604 are fixed to the four inner walls of the lamp shade 7. At the four end corners of the upper surface of the fixing plate 604, micro electric telescopic rods 603 are fixed. The tops of the four micro electric telescopic rods 603 are fixed to an adjusting plate 601. A main control driver 611 is fixed on the upper surface of the fixing plate 604. A plurality of linearly arranged split lighting strips 605 are installed on the outside of the fixing plate 604. The main control driver 611 is electrically connected to the split lighting strips 605. The traditional LED lighting fixture is divided into a plurality of split lighting strips 605 that are independent of each other and have lighting structures. The plurality of split lighting strips 605 are used for lighting together. When there are fewer pedestrians on the road at night, half of the split lighting strips 605 are used for lighting, and the lit split lighting strips 605 and the unused split lighting strips 605 are distributed at intervals, ensuring the lighting requirements of the street lamp while reducing power consumption and realizing energy conservation and environmental protection.

[0022] A reset connecting plate 607 is fixed to the outside of the condenser plate 602. Guide connection grooves 609 are provided through both ends of the reset connecting plate 607. A guide limiting rod 608 is inserted into the inside of the guide connection grooves 609. The bottom end of the guide limiting rod 608 is fixed to the fixing plate 604. A reset spring 610 is sleeved on the outside of the bottom end of the guide limiting rod 608. The top end of the reset spring 610 contacts the bottom surface of the reset connecting plate 607. A circular plate is fixed to the outside of the top end of the guide limiting rod 608. The bottom surface of the circular plate contacts the upper surface of the reset connecting plate 607 and its diameter is larger than the width of the guide connection groove 609. The reset connecting plate 607 and the condenser plate 602 are supported by the reset spring 610, ensuring that before the adjusting plate 601 descends, the condenser plate 602 will not separate the adjacent split lighting strips 605, and the reset connecting plate 607 will not fall off the outside of the guide limiting rod 608.

[0023] As Figure 6As shown, the surface of the fixed plate 604 is also provided with a plurality of circular holes linearly distributed. The split lighting strip 605 includes a single-unit control driver 6052. The single-unit control driver 6052 is fixed on the upper surface of the fixed plate 604, and a control connection line 6054 is fixed at one end of the single-unit control driver 6052. The single-unit control driver 6052 is electrically connected to the main control driver 611. A lamp bead fixing strip 6051 is provided directly below the single-unit control driver 6052. The lamp bead fixing strip 6051 is fixed on the bottom surface of the fixed plate 604, and a plurality of LED lamp beads 6053 are linearly arrayed and fixed on the bottom surface of the lamp bead fixing strip 6051. One end of the lamp bead fixing strip 6051 is fixedly connected to the control connection line 6054. The other end of the control connection line 6054 passes through the circular hole from the bottom of the circular hole and is fixed to one end of the single-unit control driver 6052. By controlling the start or shutdown of the LED lamp beads 6053 at the bottom of the lamp bead fixing strip 6051 through the single-unit control driver 6052, the independent operation of the split lighting strip 605 is realized, so as to reduce the current loss of the street lamp at night.

[0024] As Figure 4 and Figure 7 shown, the upper surface of the fixed plate 604 is also provided with a plurality of linearly arranged positioning grooves 612. The positioning grooves 612 are located in the middle position between two adjacent circular holes. Below the adjusting plate 601, there are multiple groups of linearly arranged light reflection structures. Each group of light reflection structures includes two symmetrically distributed condenser plates 602. The two symmetric condenser plates 602 are in a V shape. The bottom end of the condenser plate 602 passes through the positioning groove 612. By controlling the downward movement of the adjusting plate 601 through the micro electric telescopic rod 603, the adjusting plate 601 presses the condenser plate 602 downward, so that the two symmetric condenser plates 602 separate the operating split lighting strip 605 from the non-operating split lighting strip 605, and reflect the light generated by the operating split lighting strip 605, improving the lighting brightness of the split lighting strip 605.

[0025] The condenser plate 602 includes a guiding plate 6021. An assembly groove 6022 is provided inside the bottom end of the guiding plate 6021. An adhesive glue sheet 6023 is provided inside the assembly groove 6022. A reflective sheet 6024 is adhered to the outer surface of the adhesive glue sheet 6023. The surface of the adjusting plate 601 is provided with a plurality of linearly arranged reduced-allocation grooves 606. The reduced-allocation grooves 606 are perpendicular to the positioning grooves 612. After the condenser plate 602 separates the operating split lighting strip 605 from the non-operating split lighting strip 605, the reflective sheet 6024 reflects and enhances the light emitted by the operating split lighting strip 605, ensuring the lighting brightness of the street lamp while reducing the current loss of the street lamp.

[0026] Working principle: During the day, sunlight shines on the solar photovoltaic panel 8. The solar photovoltaic panel 8 absorbs solar energy and converts it into electric current. The converted electric current is stored inside the storage power supply of the street lamp. When the lighting conditions are insufficient after the sun goes down, the storage power supply releases the stored power and supplies it through wires to the multiple split lighting strips 605 installed inside the lamp cover 7. At this time, all the split lighting strips 605 are powered on and the LED lamp beads 6053 emit lighting light to illuminate the area around the street lamp. During the period from 0:00 to 6:00 in the morning, the number of pedestrians on the road decreases during this time period. At this time, the main control driver 611 sends a normal operation control signal to half of the split lighting strips 605. This half of the split lighting strips 605 are located between two symmetrically arranged condenser plates 602. At the same time, the main control driver 611 sends a stop operation signal to the other half of the split lighting strips 605. Since only half of the split lighting strips 605 remain in operation, it can directly reduce the current damage to the street lamp and achieve energy conservation and environmental protection of the street lamp. At this time, the operating split lighting strips 605 and the non-operating split lighting strips 605 are distributed at intervals. The power supply of the micro electric telescopic rod 603 is connected and started. The adjusting plate 601 at the top of the micro electric telescopic rod 603 moves downward and squeezes the top of the condenser plate 602 downward. The reset connecting plate 607 at the top of the condenser plate 602 moves downward and compresses the reset spring 610 until the bottom of the condenser plate 602 contacts the lamp cover 7. At this time, the condenser plate 602 separates the operating and non-operating split lighting strips 605 from each other. The reflector 6024 on the inner side of the bottom end of the condenser plate 602 reflects and enhances the light emitted by the operating LED lamp beads 6053, ensuring that the lighting brightness emitted by half of the operating LED lamp beads 6053 can illuminate the ground, ensuring that a small number of pedestrians walking on the road can observe the road conditions normally and walk without affecting the normal operation of the street lamp.
