Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Please with reference to Fig. 1 and Fig. 2, the LED street lamp 100 that the utility model detailed description of the invention provides comprises lamp holder 10, location-plate 20, heat abstractor 30, terminal plate 40, lid 50, multiple LED module 60 and multiplely covers bar 70.
Referring to Fig. 3 and Fig. 4, described heat abstractor 30 comprises multiple radiating fin 31, base plate 32 and multiple support bar 33 in plate-like.
Please refer to Fig. 5, each radiating fin 31 comprises heat-conducting part 311 and multiple holding section 312.Described heat-conducting part 311 is for being provided with the inclined plane of centre bore 313.Described holding section 312 is from the edge of described heat-conducting part 311 and towards the direction radial direction extension away from described centre bore 313.In the present embodiment, described heat-conducting part 311 is closed loop configuration, and described heat-conducting part 311 is the plane tilted.In other embodiments, described heat-conducting part 311 also can for the curved surface tilted.
Described base plate 32 is provided with the first through hole 321.
During installation, one end of described support bar 33 is fixed on described base plate 32 and is arranged around the circumferencial direction interval of described base plate 32.Described radiating fin 31 is located on described base plate 32 and is also arranged in stacked interval.Described support bar 33 surrounds described radiating fin 31, and the holding section 312 of described radiating fin 31 is fixed with corresponding support bar 33 respectively, thus makes described heat abstractor 30 form column structure.The centre bore 313 of described radiating fin 31 communicates with described first through hole 321 and jointly forms the water conservancy diversion through hole 34 of described heat abstractor 30, as shown in Figure 3.
Please refer to Fig. 1, each LED module 60 comprises substrate 61 and is located at the multiple LED 62 on described substrate 61.Described terminal plate 40 is provided with the second through hole 41, and described lid 50 is provided with third through-hole 51.
When installing described LED street lamp 100, the substrate 61 of described LED module 60 is individually fixed in the support bar 33 of described heat abstractor 30, described in cover bar 70 and hide described LED module 60 respectively.The base plate 32 of described one end and described heat abstractor 30 of covering bar 70 is fixed.Described location-plate 20 is located on described radiating fin 31, described substrate 61 through described location-plate 20, described in cover bar 70 the other end be positioned described location-plate 20.Described lamp holder 10 is fixed on described location-plate 20.The bottom of described heat abstractor 30 is located at by described terminal plate 40, and described lid 50 covers described terminal plate 40 and fixes with the base plate 32 of described heat abstractor 30.Described second through hole 41, described third through-hole 51 communicate with described water conservancy diversion through hole 34 respectively and jointly form the water conservancy diversion air holes 80 of described LED street lamp 100, as shown in Figure 1.
Because described radiating fin 31 is arranged in stacked interval, every two adjacent covering between bar 70 form multiple air port 90, and the stacked setting in described multiple air ports 90 also communicates with described water conservancy diversion air holes 80 respectively.Because the heat-conducting part 311 of described radiating fin 31 is inclined plane, therefore, described air port 90 is also arranged in tilting.
As shown in Figure 6, when described LED street lamp 100 normally works and described LED street lamp 100 is suspension status.Under the effect of draught head, the thermal current B that the heat that described LED module 60 distributes is formed upwards flows, and flows to the outside of described LED street lamp 100 by multiple air port 90.Cold airflow A constantly flows into the inside of LED street lamp 100 from the water conservancy diversion air holes 80 of bottom, thus the circulation making LED street lamp 100 define hot and cold air exchanges.
