The heat dissipation body is provided with a hollow cylinder placed in the middle, the surface of the cylinder is provided with a plurality of heat dissipation ribs, the cylinder and the heat dissipation ribs are in an integrated structure, and the heat dissipation ribs are provided with grooves along the longitudinal direction. The LED lamp is good in heat dissipation effect, low in production cost, and small in size.
Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of LED lamp.
Background technology
Existing LED lamp generally comprises several parts of LED, PCB, led driver and radiator and forms.At LED a Transparent lamp shade is arranged.Because LED lamp caloric value is large, existing LED lamp normally reaches better radiating effect by the volume that increases radiator.The general aluminium material of radiator, the volume that increases radiator is tantamount to increase the consumption of aluminium, and this obviously can increase cost, and can make the LED lamp seem very heavy.Chinese patent discloses the LED lamp of a CN201020271687.X strong heat radiation, comprises LED, PCB and is positioned at connected radiator below the PCB; Characterized by further comprising the holder device of fan and fan attachment; Described fan comprises motor and flabellum, and wherein flabellum is transparent fillet shape; Fan is positioned at the top position in the bright dipping outside of described LED, and it is facing to the LED above the PCB, and the motor of fan is positioned at the centre position of fan; Fan is fixed in the association of PCB and described radiator by holder device.The radiator of above-mentioned bulb lamp is provided with larger radiating surface, and it is more timely to dispel the heat, but the barrel of cylindrical shell and heat radiation rib all are closed, and this has just restricted the further raising with the contact with air area.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of good heat dissipation effect, production cost is low, volume is little LED lamp are provided.
The utility model is achieved by the following technical solution:
A kind of LED lamp, comprise LED, PCB, be positioned at the holder device of connected radiator below the PCB, fan and fan attachment, described radiator is provided with the hollow form cylindrical shell that is positioned at central authorities, drum surface is provided with many heat radiation ribs, cylindrical shell and heat radiation rib are integral structure, and described heat radiation rib is vertically arranged with groove.
Described groove comprises and is positioned at every heat radiation rib outer rim set outer groove, and the inner groovy that is positioned at every heat radiation rib side.
Described fan comprises motor and flabellum, and wherein flabellum is transparent fillet shape; Fan is positioned at the top position in the bright dipping outside of described LED, and it is facing to the LED above the PCB, and the motor of fan is positioned at the centre position of fan; Fan is fixed in the association of PCB and described radiator by holder device; The through hole that passes PCB and radiator is arranged at described PCB.
Described holder device comprises a stand tube and at least one support accent, is the electric wire of described motor in the described stand tube.
Described cylindrical shell is divided into upper shell and lower shell, wherein has the gap between upper shell and the lower shell, and upper shell, lower shell all rib is integrated is connected with heat radiation.
All heat radiation ribs and cylindrical shell form the heronsbill shape.
Described LED lamp body comprises LED wick and substrate, and described LED wick is the COB wick.
The utility model compared with prior art, the utility model has the following advantages and beneficial effect compared to existing technology: the heat radiation rib of the utility model LED bulb lamp is vertically arranged with groove, so that the contact area of heat radiation rib and air increases, reached higher radiating effect.Simultaneously, the utility model can be from the front of LED to its blowing or exhausting, and air-flow carries out gaseous exchange through being in the pore structure on the PCB.The lampshade functor that such design will not possess radiating effect has originally also possessed radiating effect.Because this structure is the heat radiation for the LED front, can directly reduce like this temperature of LED packaging plastic, for the so at high temperature packaging plastic of easy flavescence sex change of epoxy resin, the utility model can prolong its life-span, and makes LED keep for more time stable high light-emitting rate.The LED wick adopts the COB wick, installs more easyly, and radiating effect is better.
