Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides the following technical solutions: the utility model provides a LED street lamp that double-chamber formula heat dissipation reliability is high, including last lamp shade 1 and the lower lamp shade 3 of being connected with last lamp shade 1 through heating panel 2, install LED lamp plate 4 in the lower lamp shade 3, the top of LED lamp plate 4 is equipped with radiator 5, and radiator 5's top hugs closely the bottom of heating panel 2, the fixed of the interior slope formula of going up lamp shade 1 is equipped with diversion and heat dissipation board 6, diversion and heat dissipation board 6 divide into first heat dissipation chamber 7 and second heat dissipation chamber 8 with the inside of last lamp shade 1, there are a plurality of heat-conducting plates 9 along length direction interval distribution in the first heat dissipation chamber 7, inlet 10 has been seted up to top one side in second heat dissipation chamber 8, liquid outlet 11 has been seted up to the side of opposite side, and inside there are a plurality of guide plates 12 along width direction interval distribution.

The heat radiator 5 transfers heat into the first heat dissipation cavity 7 through the heat dissipation plate 2, the heat is transferred into the second heat dissipation cavity 8 through the heat conduction plate 9 and the diversion heat dissipation plate 6, and then the heat is dissipated through the liquid inlet 10 and the liquid outlet 11;
