Description

Technical Field

[0001] This utility model belongs to the field of floodlight technology, specifically relating to a floodlight that can efficiently dissipate heat and has dual driving power supplies. Background Technology

[0002] Floodlights, as an important component of lighting equipment, are widely used in industrial and mining sites, stadiums, building facades, and outdoor lighting. Their main function is to provide a high-brightness, long-distance illumination source. Existing floodlights typically consist of a lamp body, a light source assembly, a light-transmitting panel, and a driver power supply. Light is emitted through the light source panel, and illumination is formed through the light-transmitting panel and lampshade.

[0003] However, the heat dissipation structure design of traditional floodlights is inadequate. Most existing floodlights rely solely on the heat-conducting metal material of the lamp body for heat dissipation, lacking effective heat dissipation fins, ventilation openings, or air circulation structures. This leads to overheating of the light source panel and power supply components during prolonged operation, thereby affecting the brightness stability and lifespan of the light source.

[0004] Existing floodlight power systems are often limited to a single driver. If this driver fails, the lights cannot continue operating, causing lighting interruptions and posing safety hazards. This problem of limited power supply is particularly pronounced in outdoor or critical lighting locations, resulting in insufficient reliability.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0006] In view of the technical problems mentioned in the background art, the purpose of this utility model is to provide a floodlight to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a floodlight comprising a mounting body, a mounting groove recessed in the center of the mounting body, a light source plate mounted on the inner surface of the mounting groove, a panel groove recessed at the inner edge of the opening of the mounting groove, a light-transmitting panel embedded in the panel groove, the light-transmitting panel being correspondingly disposed at the front end of the light source plate, a power supply mounting bracket mounted on the back of the mounting body, a first driving power supply and a second driving power supply respectively mounted on the surface of the power supply mounting bracket, the first driving power supply and the second driving power supply being electrically connected to the light source plate respectively.

[0008] Furthermore, the back of the lamp holder is uniformly provided with several heat dissipation fins, which are arranged in sequence at intervals to form a longitudinally arranged heat dissipation channel structure.

[0009] Furthermore, the surface edge of the lamp holder is evenly provided with several ventilation openings, which are located at the front end of the heat dissipation fin.

[0010] Furthermore, the lamp holder has symmetrical mounting side plates on both sides, and the power supply mounting bracket has symmetrical bracket side plates on both sides. The two bracket side plates are correspondingly arranged on the upper side of the two mounting side plates. The surface of the bracket side plate has a first bracket through hole, and the surface of the mounting side plate has a second bracket through hole. Fasteners are connected and fixed by passing through the first bracket through hole and the second bracket through hole.

[0011] Furthermore, the power supply mounting bracket is symmetrically provided with heat dissipation side plates on the front and rear sides, and the surface of the heat dissipation side plates is uniformly provided with a number of heat dissipation openings, which are arranged longitudinally.

[0012] Furthermore, a first power mounting position is provided on one side of the surface of the power mounting bracket, and a second power mounting position is provided on the other side of the surface of the power mounting bracket. The first driving power supply is fixedly mounted on the first power mounting position by fasteners, and the second driving power supply is fixedly mounted on the second power mounting position by fasteners. The first power mounting position and the second power mounting position are spaced apart, forming an air circulation gap between them.

[0013] Furthermore, the light source panel is fixedly installed on the inner surface of the lamp body mounting groove by fasteners, and the edge of the light-transmitting panel is fixed to the edge of the panel groove by adhesive. A spotlight cover is installed at the front end of the lamp body, and the spotlight cover covers the outside of the light-transmitting panel.

The number of lamp cover through blocks and the number of lamp cover through holes correspond one-to-one, and are connected and fixed by fasteners passing through the lamp cover through blocks and lamp cover through holes.

[0015] Furthermore, the outer side of the lamp mounting body is movably connected to a mounting bracket. The two ends of the mounting bracket are symmetrically provided with first bracket mounting holes, and the middle of the surface of the two mounting side plates is provided with second bracket mounting holes. The first bracket mounting holes and the second bracket mounting holes correspond to each other and are hingedly connected by fasteners passing through the first bracket mounting holes and the second bracket mounting holes.

[0016] Furthermore, the heat dissipation fin and the lamp mounting body are integrally die-cast.

Detailed Implementation

[0023] like Figures 1 to 4As shown, a floodlight includes a mounting body 10. A mounting groove 11 is recessed in the center of the mounting body 10, and a light source plate 20 is mounted on the inner surface of the mounting groove 11 to provide illumination. A panel groove 12 is recessed at the inner edge of the opening of the mounting groove 11, and a light-transmitting panel 30 is embedded in the panel groove 12. The light-transmitting panel 30 is made of high-transmittance tempered glass or PC material, used to protect the light source and transmit light. The light-transmitting panel 30 is correspondingly positioned at the front end of the light source plate 20. A power supply mounting bracket 40 is mounted on the back of the mounting body 10. A first driving power supply 50 and a second driving power supply 60 are respectively mounted on the surface of the power supply mounting bracket 40. The first driving power supply 50 and the second driving power supply 60 are electrically connected to the light source plate 20. When the first driving power supply 50 fails, the second driving power supply 60 can automatically take over the power supply, ensuring the floodlight continues to operate normally, thereby improving the reliability and safety of the lighting.

[0024] In practical implementation, the back of the lamp mounting body 10 is uniformly provided with a plurality of heat dissipation fins 13, which are arranged sequentially and at intervals to form a longitudinally arranged heat dissipation channel structure. The arrangement of these heat dissipation fins 13 effectively increases the heat dissipation area on the back of the lamp body, improving the overall thermal conductivity of the lamp body. The surface edge of the lamp mounting body 10 is uniformly provided with a plurality of air passage openings 14, which are located at the front end of the heat dissipation fins 13. This design allows air to form natural convection between the inside and outside of the lamp body, significantly improving heat dissipation efficiency. The heat dissipation fins 13 and the lamp mounting body 10 are integrally die-cast, ensuring consistent thermal conductivity and high structural strength, avoiding problems such as loosening of contact or increased thermal resistance due to long-term thermal expansion and contraction.

[0025] In practical implementation, mounting side plates 15 are symmetrically arranged on both sides of the lamp mounting body 10, and bracket side plates 41 are symmetrically arranged on the left and right sides of the power mounting bracket 40. The two bracket side plates 41 are correspondingly arranged on the upper side of the two mounting side plates 15. The surface of the bracket side plate 41 is provided with a first bracket through hole 411, and the surface of the mounting side plate 15 is provided with a second bracket through hole 151. Fasteners are connected and fixed by passing through the first bracket through hole 411 and the second bracket through hole 151, so that the power mounting bracket 40 is fixedly installed on the back of the lamp mounting body 10. This structural design can achieve reliable fixation of the power mounting bracket 40, and at the same time facilitate subsequent assembly and maintenance. The power mounting bracket 40 has symmetrical heat dissipation side plates 42 on its front and rear sides. Each heat dissipation side plate 42 has a plurality of heat dissipation openings 421 evenly distributed on its surface. These openings 421 are arranged longitudinally, creating an airflow path when the floodlight is operating. This allows for convection ventilation between the inside of the power mounting bracket 40 and the outside air, accelerating heat dissipation from the power components and preventing instability in high-temperature environments. During use, the heat generated when the light source panel 20 is powered on is conducted to the outside air through the lamp body mounting slot 11 and the heat dissipation fins 13. Simultaneously, heat within the power mounting bracket 40 is exhausted through the heat dissipation openings 421, forming an integrated cooling system that significantly improves the floodlight's heat dissipation efficiency and operational stability.

[0026] In practical implementation, the power mounting bracket 40 has a first power mounting position 43 on one side of its surface and a second power mounting position 44 on the other side. The first drive power supply 50 is fixedly mounted on the first power mounting position 43 with fasteners, and the second drive power supply 60 is fixedly mounted on the second power mounting position 44 with fasteners. This structural design allows the two sets of drive power supplies to be installed independently, which facilitates assembly and maintenance and achieves symmetrical heat dissipation in terms of spatial layout. The first power mounting position 43 and the second power mounting position 44 are spaced apart, forming an airflow gap between them to allow air to flow in or out through the heat dissipation opening 421, thereby accelerating the heat dissipation efficiency of the power module and preventing performance degradation due to overheating. Through the above structural design, the first drive power supply 50 and the second drive power supply 60 not only achieve a stable connection in mechanical installation, but also effectively optimize heat conduction and heat dissipation performance, thereby improving the working stability and service life of the dual drive system.

[0027] In practical implementation, the light source panel 20 is fixedly installed on the inner surface of the lamp body mounting groove 11 with fasteners to ensure that the light source panel 20 is stable and reliable. The edge of the light-transmitting panel 30 is fixed to the edge of the panel groove 12 with adhesive. A spotlight cover 70 is installed at the front end of the lamp body 10, and the spotlight cover 70 covers the outside of the light-transmitting panel 30. A spotlight cup 80 is provided between the light source panel 20 and the light-transmitting panel 30. The spotlight cup 80 is located on the inner edge of the lamp body mounting groove 11. The spotlight cup 80 is used to collect the light emitted by the light source panel 20 and perform preliminary focusing, so that the light passing through the light-transmitting panel 30 and the spotlight cover 70 forms a more uniform and concentrated beam, improving the lighting effect and light utilization rate.

[0028] In practical implementation, the outer edge of the spotlight cover 70 is evenly provided with a number of cover through blocks 71, and the outer edge of the panel groove 12 is evenly provided with a number of cover through holes 121. The number of cover through blocks 71 and the number of cover through holes 121 correspond one to one, and are connected and fixed by fasteners passing through the cover through blocks 71 and the cover through holes 121. Through this structural design, the spotlight cover 70 can be reliably fixed at the front end of the mounting lamp body 10.

[0029] In practical implementation, the outer side of the lamp mounting body 10 is movably connected to a mounting bracket 90. The two ends of the mounting bracket 90 are symmetrically provided with first bracket mounting holes 91, and the middle of the surface of the two mounting side plates 15 is provided with second bracket mounting holes 152. The first bracket mounting holes 91 and the second bracket mounting holes 152 correspond to each other and are hinged to each other by fasteners passing through the first bracket mounting holes 91 and the second bracket mounting holes 152, so that the mounting bracket 90 can rotate freely around the hinge point to realize the angle adjustment of the floodlight.

[0030] In practical implementation, a wire-passing opening 16 is provided in the middle of the lamp mounting body 10 for the power line or control line to be led out from the inside of the lamp body to realize the electrical connection between the light source board 20 and the first driving power supply 50 and the second driving power supply 60.

[0031] In summary, this floodlight utilizes the heat dissipation fins 13 and ventilation openings 14 on the back of the lamp body 10, along with the heat dissipation side plate 42 and heat dissipation openings 421 of the power supply mounting bracket 40, to form an integrated heat dissipation channel. This achieves efficient heat dissipation for the lamp body mounting slot 11 and the first and second driving power supplies 50 and 60, ensuring stable operation of the light source board 20 and the first and second driving power supplies 50 and 60 in high-temperature environments. The dual-drive redundant power supply design of the first and second driving power supplies 50 and 60 allows the second driving power supply 60 to automatically take over power supply when the first driving power supply 50 fails, improving the reliability and safety of the floodlight. The rational combination of the light source board 20, the spotlight cup 80, the light-transmitting panel 30, and the spotlight cover 70 allows light to be focused by the spotlight cup 80, passed through the light-transmitting panel 30, and guided by the spotlight cover 70 to form uniform, concentrated, and high-brightness illumination, improving light utilization and lighting effect.
