The utility model relates to a kind of lighting source, particularly a kind of LED street lamp.
[background technology]
Existing LED street lamp adopts mostly great power LED is installed on the fin, makes behind its outside installation lamp housing then, and the great power LED illumination effect is relatively good, but because of its drive current is bigger, so its caloric value is also very big, is unfavorable for long-term operation; And because the LED street lamp is installed in outdoorly, the time has been grown the easy topped dust and other impurities of street lamp shell, influences the street lamp heat and outwards transmits, and can shorten the service life of LED street lamp greatly.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of heat-dissipating casing that can solve existing LED road lamp cooling efficient LED street lamp on the low side.
The utility model is achieved in that a kind of heat-dissipating casing of LED street lamp, comprise street lamp base, upper cover plate, outer aluminium sheet and internal layer aluminium sheet, described heat-dissipating casing is the truncated conical shape with inside and outside double side walls, wherein internal layer aluminium sheet and outer aluminium sheet surround the interior lateral wall of round platform respectively, and outer aluminium sheet is set in the outside of internal layer aluminium sheet.Form cavity together between outer aluminium sheet and the internal layer aluminium sheet, described upper cover plate is arranged on the end face of the top of internal layer aluminium sheet and outer aluminium sheet as round platform, street lamp base is arranged on the bottom surface of the bottom of internal layer aluminium sheet and outer aluminium sheet as round platform, and described upper cover plate and street lamp base are equipped with through hole.
Forming by the screw fixed combination by two onesize semicircle platform casing assemblies at least of described heat-dissipating casing.
The outer surface of described outer aluminium sheet is provided with some heat radiation tooth bars.
The outer surface of described internal layer aluminium sheet is provided with some heat radiation tooth bars.
The bottom of described street lamp base connects aluminium base with screw, is marked with heat-conducting glue between aluminium base and the street lamp base.
Advantage of the present utility model is: adopt the heat-dissipating casing of the LED street lamp of this kind structure, can produce three thermoprecipitations, improve heat dispersion greatly.Described led chip is installed and is bumped in the aluminium base, filling heat-conductive glue between aluminium base and street lamp base, aluminium base is connected with screw with the street lamp shell, and led chip carries out the transition on the street lamp base by the thermal diffusion layer that aluminium base and heat-conducting glue form, and finishes thermoprecipitation for the first time; By being connected of street lamp base and internal layer aluminium sheet,, finish thermoprecipitation for the second time with heat transferred internal layer aluminium sheet; The internal layer aluminium sheet is finished thermoprecipitation for the third time with the outer aluminium sheet of heat transferred.This heat-dissipating casing structure is compared with existing LED road lamp cooling structure, and its radiating efficiency can improve 20%, thereby LED street lamp product stability is greatly improved.
