Definitions

  • the present invention relates to an LED road light, and more particularly to an LED road light assembled by engagements between ribs and slots formed on parts of the LED road light.
  • LED road lights have gradually become the mainstream road lights.
  • the high heat issue is still a problem of the LED lights.
  • a large heat dissipation board additionally mounted to an LED road light is a main technical measure to tackle the issue, but it also gives rise to assembling problems.
  • a conventional LED road light has a top cover 50, a bottom cover 60 and an LED module 70.
  • the top cover 50 has a lamp pole sleeve 51 and two upper wings 52.
  • the lamp pole sleeve 51 is formed on and protrudes from a rear end of the top cover 50.
  • the two upper wings 52 are respectively formed on and protrude downwardly from two sides of the top cover 50.
  • Each upper wing 52 has multiple through holes formed through the upper wing 52.
  • the bottom cover 60 has two lower wings 61, multiple light holes 612 and multiple screw holes 613.
  • the two lower wings 61 are respectively formed on and protrude upwardly from two sides of the bottom cover 60.
  • Each lower wing 61 has multiple through holes 611 formed through the lower wing 61.
  • multiple bolts 80 are respectively mounted through the through holes 521, 621 to combine the top cover 50 and the bottom cover 60 together.
  • the light holes 612 are formed through the bottom cover 60.
  • the screw holes 613 are formed through the bottom cover 60 and are adjacent to the light holes 612.
  • the LED module 70 is mounted between the top cover 50 and the bottom cover 60 and has multiple LED strips 71.
  • the LED strips 71 are parallel with each other and each LED strip 71 has a hollow metal bar 711 and multiple LED elements 712.
  • the LED elements 712 are mounted in a bottom of the metal bar 711 and align with and respectively illuminate through the light holes 612.
  • Each LED element 712 aligns with at least one of the screw holes 613 and is fastened on the bottom cover 60 by screwing multiple screws 713 into the LED element 712 through the screw holes 613.
  • the conventional LED road light may be loosened and come off after a period of outdoor operation. Besides frequent maintenance, the risk of jeopardizing public safety is also high and the assembly of the conventional LED road light consumes labor-hours.
  • An objective of the present invention is to provide an LED road light assembled by using ribs and slots formed on parts of the LED road light and mounting ribs into corresponding slots to provide higher combined strength thereof and more convenient assembly process.
  • the LED road light a heat sink, an LED module, a base and a light pole holder assembly.
  • the heat sink has a top, a bottom, a light opening and multiple first sliding slots.
  • the light opening is centrally formed through the heat sink.
  • the first sliding slots are formed in the top of the heat sink.
  • the LED module is mounted to the light opening of the heat sink to illuminate downwardly through the light opening.
  • the base has a top, a bottom, multiple first sliding ribs and multiple second sliding slots.
  • the first sliding ribs are formed on and protrude downwardly from the bottom of the base, and respectively align with and are slidably mounted in the first sliding slots on the top of the heat sink.
  • the second sliding slots are formed in the top of the base.
  • the light pole holder assembly has a bottom and multiple second sliding ribs.
  • the second sliding ribs are formed on and protrude downwardly from the bottom of the light pole holder assembly, and respectively align with and are slidably mounted in the second sliding slots on the top of the base.
  • the LED road light of the present invention employs ribs and slots formed on the base, the heat sink and the light pole holder to assembly those parts by slidably mounting the ribs into the corresponding sliding slots. Due to larger contact area of the engagement, the combined strength of the LED road light is relatively higher and thus results in more stable structure. Moreover, sliding mounting ribs into corresponding slots is convenient and time-saving for workers to assembly the LED road light.
