DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 -3 depict preferred embodiments of the improved LED outdoor light of the present invention, which, however, are provided for only explanatory objective. Said LED outdoor light A comprising: an electric control housing 10, made of a hollow structure, including: a front end 11, a rear end 12 and left and right surfaces 13, 14. An electric control module 15 is set into the electric control housing; a lighting housing 20, extended and located in front of the electric control housing 10. A vertical through-portion 21 is set in the center of the lighting housing 20, with two assembled rod sections 22 extended and formed at both sides; at least an LED lighting dcvicc 30, cxtcndcd and located across two assembled rod scctions 22, and also electrically connected with the electric control module 15 to control on/off state of the LED lighting dcvicc 30. The LED lighting dcvicc comprises of: a circuit board 31, several radiating fins 32 set on top surface of the circuit board 31, and several LED bulbs 33 set on bottom surface of the circuit board 31. Said LED bulbs 33 arc exposcd below the lighting housing 20 so as to give out irradiation light sources (shown in FIG. 5 and FIG. 8). Besides, the LED lighting device 30 is coated with a dampproof layer to protect the LED lighting device 30 against damage from water penetration; two rotary side covers 40, pivoted over two assembled rod sections 22, including: a pivoted end 41, a rotary end 42, an internal surface 43 and an external surface 44. The rotary side covers 40 may rotate internally by taking the pivoted end 41 as the pivot point, and then are located partially at two sides of the vertical through-portion 21; a rotary upper cover 50, pivoted at the front end of the electric contitl housing 10 via a pivoting portion 51, and rotating forward to be limited over these two rotary side covers 40, so as to prevent dust or dirt entering the lighting housing 20 by fully covering the vertical through-portion 21. Moreover, a gap is reserved between the rotary upper cover 50 and two rotary side covers 40.

As the vertical through-portion 21 is fully covered, it's possible to prevent external dirt (such as bird droppings and sand) entering the lighting housing 20; subsequently, this could avoid affecting heat-dissipating function of the LED lighting device 30 and shortening the service life; an assembled limiting portion 45, extended to the front cnd of these two assembled rod sections 22. A framed structure is formed among these two assembled rod sections 22, the assembled limiting portion 45 and the electric control housing 10. Moreover, the assembled limiting portion 45 is set to assemble these two rotary side covers 40 and the Mary upper cover 50; a heat-dissipating space 70, shown in FIG 5, lbrmed by the space between the rotary upper cover 50 and two rotary side covers 40.

Referring to FIGS. 4 and 5, a locating jack 46 is set on the bottom suthce of these two rotary side covers 40 and the rotary upper cover 50. The assembled limiting portion 45 is set to slide forth and back (indicated by arrow LI in FIG 4). Several convex columns 451 are set inside the assembled limiting portion 45 correspondingly to the locating jack 46. So, when the assembled limiting portion 45 slides backward, the convex columns 451 could be inserted into the locating jack 46 (shown in FIG 5), such that thcsc two rotary sidc covcrs 40 and the rotary upper cover 50 are locked. As shown in FIG 4, while the assembled limiting portion 45 slides forward, the convex columns 451 arc disengaged from the locating jack 46, such that these two rotary sidc covcrs 40 and the rotary upper cover 50 are in freely rotary state.

Of which, the LED lighting device 30 is designed into a single unit or multiple units. And, at least a second heat-dissipating space 71 is formed between the LED lighting device 30 and the bottom of the lighting housing 20 for heat convection with the heat-dissipating space 70. Referring to FIG 8, the LED outdoor light A comprises three LED lighting devices 30, each of which is located at interval; so several second heat-dissipating spaces 71 are formed at the bottom of the lighting housing 20; this could realize heat convection with the heat-dissipating space 70 and strengthen the radiation efficiency of LED outdoor light A. Referring to FIG 7, when these two rotary side covers 40 are located partially on both sides of the vertical through-portion 21, the external surface 44 may lean downward towards both sides of the lighting housing 20, so that liquid could flow out along the external surface 44 for preventing the liquid flowing from the heat-dissipating space 70 to the lighting housing 20. As the LED lighting device 30 is fully coated with a dampproof layer, the lighting housing 20 is protected against any damage arising from water penetration into the lighting housing 20.

Referring to FIGS. 5 and 6, a threaded bolt 61 is limited at the front end of the rotary upper cover 50. A screw hole 62 is set inside the assembled limiting portion 45 correspondingly to the threaded bolt 61. When thc rotary upper cover 50 is rotarily set over these two rotary sidc covers 40, it could be screwed securely onto the assembled limiting portion 45.

Based on above-specified structural description, thc present invention is operated as follows.

Referring to FIG 3, when it's intended for repair or replacement of the LED lighting device 30, these two rotary side covers 40 and the rotary upper cover 50 could be rotarily opened, and the vertical thmugh-portion 21 is kept open, allowing to take out smoothly the LED lighting device 30 (shown in FIG. 2).

ReferringtoFlG5,thepresentinventionismainlycharacterizedbythat, agapisreserved between the rotary upper cover 50 and these two rotary side covers 40, so that a heat-dissipating space 70 is formed accordingly; this enables heat generated by the LED lighting device 30 to be dissipated from the heat-dissipating space 70, thus realizing better heat-dissipating flinction and cxtcnding grcatly thc scrvicc lifc of thc LED outdoor light A.
