Abstract

An LED street lighting fixture assembled by attaching a rib to a slot to provide a higher bonding strength and a more convenient assembly process of the LED street lighting fixture. An LED street lighting device includes a heat sink (10) fitted into an LED module (20), a base (30), and a lighting pole holder assembly (40). The base, heat sink and lighting pole holder assembly are assembled by slidably mounting ribs 31, 41, 31a in slots 11, 32, 11a. The contact area of such engagement is wider than the engagement area of engagement using a screw, so that the bonding strength of the LED road lighting fixture can be increased and the life of the LED road lighting fixture can be extended. Further, an engagement mechanism using ribs and slots is convenient and reduces the time required for assembly. [Selection diagram] Fig. 1

Description

  The present invention relates to an LED road lighting device, and more particularly, to an LED road lighting device assembled by engagement of a rib formed on a part and a slot.

  LED road lighting fixtures with low power consumption and high brightness are gradually becoming mainstream road lighting fixtures. Despite LED street lighting fixtures saving power, high heat release is a problem with LED lighting fixtures. Large heat sinks attached to LED road lighting fixtures are the main technical means for high heat release, but the heat sinks cause assembly problems.

  As shown in FIG. 6, the conventional LED road lighting device includes a top cover 50, a bottom cover 60, and an LED module 70.

  The top cover 50 includes a lamp pole sleeve 51 and two upper wings 52. The lamp pole sleeve 51 is formed at the rear end portion of the top cover 50 and protrudes from the rear end portion. The upper wing 52 is formed on two sides of the top cover 50 and protrudes downward from the side. Each upper wing 52 has a plurality of through holes 521.

The LED strips 71 are parallel to each other, and each LED strip 71 includes a hollow metal bar 711 and a plurality of LED elements 712. The LED element 712 is attached to the bottom of the metal bar 711, aligned with the illumination hole 612, and illuminates through the illumination hole. Each LED element 712 is aligned with at least one of the screw holes 613 and fixed to the bottom cover 60 by screwing a plurality of screws 713 into the LED elements 712 through the screw holes 613.

  Since the LED module 70 of the conventional LED road lighting device is coupled to the bottom cover 60 by screws and the top cover 50 is fixed to the bottom cover 60 by screws, the LED road lighting device is loosened after outdoor use, It may come off. In addition to frequent maintenance, public safety is likely to be compromised, and assembly of the LED road light fixture requires a lot of labor and time.

  An object of the present invention is to use ribs and slots formed in parts of the LED road lighting device in order to provide a higher coupling strength and a more convenient assembly process of the LED road lighting device. It is to provide an LED road light fixture assembled by attaching to the slot.

  To achieve the above object, an LED road lighting fixture includes a heat sink, an LED module, a base, and a lighting pole holder assembly.

  The heat sink has a top portion, a bottom portion, an illumination opening, and a plurality of first sliding slots. The illumination opening is formed at a central portion of the heat sink and penetrates the central portion. The first sliding slot is formed at the top of the heat sink.

  The LED module is attached to the illumination opening of the heat sink to illuminate downward from the illumination opening.

  The base includes a top portion, a bottom portion, a plurality of first sliding ribs, and a plurality of second sliding slots. The first sliding rib is formed at the bottom of the base, protrudes downward from the bottom, is aligned with the first sliding slot of the heat sink, and is slidably attached to the first sliding slot. The second sliding slot is formed at the top of the base.

  The illumination pole holder assembly has a bottom portion and a plurality of second sliding ribs. The second sliding rib is formed at the bottom of the lighting pole holder assembly, protrudes downward from the bottom, is aligned with the second sliding slot of the base, and is slidably attached to the second sliding slot. ing.

  The LED road light fixture includes a base, the heat sink, and the light pole holder, wherein a rib and a slot formed in the base, the heat sink, and the light pole holder assembly are slidably attached to the slot. Used to assemble the assembly. Due to the wide contact area of engagement, the coupling strength of the LED road light fixture is relatively high, resulting in a more stable structure. In addition, sliding the mounting rib into the slot is convenient and reduces the time for the operator to assemble the LED street light fixture.
