  • a power supply drive module for driving the LED is to be provided additionally.
  • the power supply drive module will emit much heat when in service, so it is disadvantageous for heat dissipation if both the LED light source and the power supply drive module are disposed within a lamp body. Therefore, the existing waterproof, moisture-proof and dustproof lamps rarely use LEDs as the light source.

  • Two covers are provided at two ends of the lamp base integratively formed with the lamp base, or two covers provided at two ends of the lamp base can be independent aluminum die-cast members and connect with the lamp base through screws, and two waterproof cushions are respectively provided between each cover and the lamp base, in order to meet the requirements of IP66 grade.
  • a sealing stip is provided between each side edge of the lampshade and each groove of the intermediate connecting piece, and the lampshade and the lamp base are connected through hasps.
  • the LED module consists of one LED strip or a plurality of LED strips which are electrically connected to each other through an SMD connector.
  • At least two of the radiating strips on the bottom surface of the intermediate connecting piece are respectively L-shaped and inverted L-shaped, so that a sliding passage is formed between these two radiating strips and the bottom surface of the intermediate connecting piece.
  • the LED lamp further comprises a power supply drive module, which is sealed in a drive housing, for driving the LED module, the drive housing being located outside the lamp body and connected to the bottom surface of the intermediate connecting piece in the lamp base.
  • Providing the power supply drive module outside the lamp body can avoid interference between the heat dissipation of the LEDs and the heat dissipation of the power supply drive module, so it is advantageous for the overall heat dissipation of the lamp body.
  • L-shaped mounting bars are formed outside the drive housing and slidingly disposed within the slide passage.
  • each waterproof joint is respectively mounted in a sealed manner on each cover plate disposed on each end of the drive housing, each waterproof joint has a through hole for wires to pass through, and the cover is also provided with a hole for wires to pass through.

  • a power supply drive module for driving the LED module is disposed outside the lamp body, and a lamp cover connected to the lamp base is also provided outside the lamp body, multiple radiating holes in a grid arrangement are provided on the lamp cover, furthermore, a sealed power supply holding chamber for holding the power supply drive module is provided within the lamp cover, and the power supply drive module is disposed within the sealed power supply holding chamber.
  • the cross section of the lamp cover in the widthwise direction is U-shaped, and the cross section thereof in the lengthwise direction is U-shaped too.
  • the lamp cover includes two cover connecting members disposed at two ends of the lamp cover and a plurality of intermediate connecting members being capable of connecting to each other and connected between the two cover connecting members, and the cover connecting members and the intermediate connecting members are all provided with the multiple radiating holes in a grid arrangement; the sealed power supply holding chamber is disposed between the two cover connecting members, and two ends of the sealed power supply holding chamber can respectively be connected to one of the intermediate connecting members.
  • lamp products of different lengths can be produced by increasing or decreasing the number of intermediate connecting members.
  • the lamp cover is connected to the bottom surface of the intermediate connecting piece of the lamp base through screws.
  • the present invention has the following advantages: as the lamp base is designed to be an integrated aluminum profile structure and the top surface of the intermediate connecting piece is designed to be planar, the intermediate connecting piece can be used as a reflector, without requiring any additional reflectors; and, as the bottom face thereof is provided with a plurality of radiating strips, the soleplate may be used as the soleplate of the lamp body and also as a radiator, so that good heat dissipation effect may be achieved.
  • the lamp cover is provided outside the lamp body, multiple radiating holes in a grid arrangement are provided on the lamp cover, and a sealed power supply holding chamber is provided within the lamp cover, on the one hand, the lamp has integrality and a nice appearance, and exposure of inner wires which would affect the nice appearance is avoided; on the other hand, the radiating holes on the lamp cover can radiate heat and directly discharge heat out from the lamp, so that the service life of the lamp is guaranteed.
