Detailed description of the invention
The invention provides a kind of efficient heat radiating LED street lamp, this LED street lamp has high efficiency and heat radiation unit, and simple and compact for structure, with low cost.Therefore this LED street lamp operating temperature is lower, thus has job stability and longer service life preferably.
Below in conjunction with following accompanying drawing, the embodiment of the present invention is described in detail.
The invention provides a kind of efficient heat radiating LED street lamp, as shown in Figure 1, this LED street lamp includes the arc radiating seat 2 that laminating is arranged on LED luminescence component 1 back side.Wherein, the back side shape of this arc radiating seat 2 is mated mutually with the back side shape of LED luminescence component.
Arc radiating seat 2 edge is provided with hasp unit 7, and hasp unit includes again elasticity butt hook and stay hook groove further; Wherein, stay hook groove is used for fixing elasticity butt hook, and elasticity butt hook is used for arc radiating seat to be fixedly connected with integral with LED luminescence component.
And as one comparatively preferred embodiment, as shown in Figure 1, LED luminescence component 1 and arc radiating seat 2 also every being provided with netted insulation catch 8, and are also filled with heat conduction silicone oil or heat conductive silica gel in the netted gap of the catch that insulate.It should be noted that the length of this insulation catch 8 is greater than the length of LED luminescence component 1, thus avoid that arc radiating seat is charged causes danger.
Further for improving the radiating effect of arc radiating seat, being provided with several heat dissipation cavity in arc radiating seat 2 inside, and a heat exchange of heat pipe 3 is all installed in each heat dissipation cavity.Concrete, as shown in Figure 2, Fig. 2 gives the sectional view of heat exchange of heat pipe.This heat exchange of heat pipe 3 is in a sealing box like structure, its housing adopts copper sheet punching press to be prepared from, wherein near arc radiating seat bottom surface for heat absorption end face (a), that deviate from arc radiating seat bottom surface is heat release end face (the cross section b shown in Fig. 2) to the cross section shown in Fig. 2; In addition, heat exchange of heat pipe 3 inside is also laid with fluid line 31, is filled with circulating cooling liquid in this fluid line 31, and heat exchange of heat pipe 3 release end of heat outer wall is also provided with radiating fin 32.When the work of LED luminescence component is luminous, namely the heat come out is absorbed by the circulating cooling liquid in heat exchange of heat pipe and evaporate takes away, then circulating cooling liquid can in the radiating fin of heat release end face heat release and condensation again drip face, resorption hot junction, so far reach the effect of heat radiator.
