  • This kind of the LED lighting apparatus has a discordant and abrupt appearance and is inconvenient to install and use.
  • an existing LED lighting apparatus is generally provided with a waterproof rubber ring and a plurality of locking screw to realize water prevention of the panel, which causes time consuming working hours during manufacture and assembly, and is troublesome in terms of disassembly.
  • the present invention intends to overcome deficiencies of the prior art and to provide an LED floodlight which is easy to mount, to replace and to maintain, and can be optionally provided with an independent sensor, and is easy to stock and prepare.
  • the present invention adopts the following technical solutions:
  • the invention comprises a lighting body being internally provided with a drive light source plate provided with LEDs, further comprises a mounting bracket and a sensor module being detachably assembled with the lighting body via a waterproof connector.
  • the sensor module is electrically connected to the drive light source plate.
  • the electric wires connecting the sensor module and the drive light source plate are passing through the waterproof connector.
  • the overall shape of the sensor module and the lighting body after being assembled is rectangular.
  • the sensor module is provided with a power line. The said power line is sealed to the sensor module via a waterproof bolt, so that the sensor module is waterproof.
  • a light-transmitting plate and a reflector are arranged in the light emitting position of the drive light source plate inside the lighting body.
  • the LED floodlight of the present invention comprises a plurality of elastic buckles, and a plurality of embedding holes are arranged on the lighting body.
  • the plurality of elastic buckles passing through the plurality of embedding holes are clamped on the lighting body on the back surface, and the light-transmitting plate is tightly clamped on the lighting body on the front side thereof.
  • each of the elastic buckles is provided with a reverse hook in order to be clamped on the back surface of the lighting body to prevent slippage.
  • a waterproof sealing ring is arranged at the joint between the light-transmitting plate and the lighting body.
  • a plurality of heat dissipation fins are arranged on the back surface of the lighting body.
  • two supporting legs are respectively arranged on both sides of the mounting bracket to be connected with the lighting body by two bolts, wherein the supporting legs are rotatably positioned with the lighting body by taking the bolt as a shaft
  • the present invention has advantageous effects as below because the present invention comprises a lighting body being internally provided with a drive light source plate provided with LEDs, a mounting bracket and a sensor module being detachably assembled with the lighting body via a waterproof connector, the sensor module is electrically connected to the drive light source plate, the electric wires connecting the sensor module and the drive light source plate are passing through the waterproof connector, the overall shape of the sensor module and the lighting body after being assembled is rectangular, the sensor module is provided with a power line, and the power line is sealed to the sensor module via a waterproof bolt, so that the sensor module is waterproof.
  • the waterproof connector being detachably connected with the lighting body, the waterproof problem of the outdoor product is solved, and the sensor module is provided as an independent optional module.
  • the invention enables independent modular production, and is convenient to assemble, furthermore the overall appearance is not discordant or abrupt when the sensor module is assembled with the lighting body as a whole, so that the customers can conveniently mount, replace and maintain the lighting apparatus and select combination for it, and for the manufacturers it is convenient to stock and prepare.
  • This invention herein is easy to mount, to replace and to maintain, can be optionally provided with an independent sensor, and is easy to stock and prepare.

  • the sensor module 3 is electrically connected to the drive light source plate 5, the electric wires connecting the sensor module 3 and the drive light source plate 5 are passing through the waterproof connector 15.
  • the overall shape of the sensor module 3 and the lighting body 1 after being assembled is rectangular.
  • the sensor module 3 is provided with a power line 10, and the power line 10 is sealed to the sensor module 3 via a waterproof bolt 9, so that the sensor module 3 is waterproof.
  • a light-transmitting plate 6 and a reflector 7 are arranged in the light emitting position of the drive light source plate 5 inside the lighting body 1.
  • the LED floodlight further comprises four elastic buckles 8, and four embedding holes 12 are arranged on the lighting body 1.
  • the four elastic buckles 8 respectively passing through the four embedding holes 12 are clamped on the lighting body 1 on the back surface, and the light-transmitting plate 6 is tightly clamped on the lighting body 1 on the front side thereof.
  • Each of the elastic buckles 8 is provided with a reverse hook 81 to be clamped on the back surface of the lighting body 1 to prevent slippage.
  • a waterproof sealing ring 14 is arranged at the joint between the light-transmitting plate 6 and the lighting body 1.
  • a special spring buckle design is adopted, it could be firmly pressed against the light-transmitting plate 6 and the waterproof sealing ring 14 by matching with the structure of the lighting body 1, so as to reach the purpose of waterproofing.
  • the buckles 8 have an anti-loosening function, that means it can be dismantled only with the help of tools, which leads to reduction of material costs of the product and reduction of production and assembling working hours.
  • a plurality of heat dissipation fins 11 are arranged on the back surface of the lighting body 1, it brings heat dissipation well under the condition of the small size of the product.
