Description
Technical field
The present invention relates to a kind of heat abstractor of LED lamp, particularly a kind of LED lamp fan heat sink.
Background technology
In prior art, LED lamp includes lamp socket, lamp pearl post, lamp driving circuit, lamp holder and bulb, lamp holder access power supply, and connect lamp socket, lamp driving circuit is placed in the inner chamber of lamp socket from below, and one end connects power supply, the lamp pearl plate of the other end then on connecting lamp pearl post; Lamp pearl post is positioned at above lamp socket, is fixedly connected with lamp socket, and bulb is a kind of transparent or nontransparent housing, covers lamp bulb seat and is connected with lamp socket is airtight.
Described lamp socket is as the radiator of light fixture, and it generally leaves heat dissipation channel, is convenient to the convective exchange of air in light fixture.But, this radiating mode is passive, on lamp socket, be normally provided with the hole inside and outside connection, then carry out with the cold-hot characteristic that air is own, radiating convection speed is slow, and therefore radiating effect is also very limited, particularly for larger light fixture, its radiating effect is poorer, have impact on result of use and the service life of light fixture widely.
Summary of the invention
The object of the invention is to provide a kind of good heat dissipation effect according to the deficiencies in the prior art part, guarantee the LED lamp fan heat sink in light fixture result of use and service life.
The object of the invention is to be realized by following approach:
LED lamp fan heat sink, its structural feature is, includes lamp holder upper cover, fan, fixed head and installs the heat-dissipating cylinder of lamp pearl; Heat-dissipating cylinder is hollow ring barrel-shaped structure, outer peripheral face is provided with lamp pearl; The centre of fixed head is the cylindrical member of a hollow, described heat-dissipating cylinder is fixedly mounted on the below of fixed head, simultaneously the inner chamber of heat-dissipating cylinder is corresponding with this cylindrical member inner chamber and be communicated with, fan is arranged in the cylindrical member of fixed head, air port is facing to the inner chamber of heat-dissipating cylinder, lamp holder top cap is connected to above fixed head, and heat-dissipating cylinder then cover cap a lampshade, and this lampshade is connected to the below of fixed head.
Fan a kind ofly drives heat to reach by accelerating air flowing, to the equipment of the objects such as wind, consider that it reaches the fan blade driving heat, need certain length and area to objects such as wind, and power needs motor, therefore need certain volume and weight.And the most volume of LED lamp is little, and it is normally installed, is suspended on ceiling or aerial, needs to reduce weight as much as possible, therefore never considers fan to be applied in LED lamp in this area.The present invention breaches this theory, fan and light fixture are organically combined: first the heat-dissipating cylinder installing lamp pearl is provided, the inner chamber of heat-dissipating cylinder is as the air channel of fan, fan can provide convection effects fast, take away rapidly because lamp pearl sends out heat thermogenetic on heat-dissipating cylinder, realize excellent heat radiation object; Secondly, because fan can provide larger cross-ventilation, therefore also need the convection space that light fixture provides larger, adopt heat-dissipating cylinder as air channel, inner circumferential surface is large, and the space provided is also enough large, so can obtain better radiating effect; Further, fan is the powerful radiating effect that LED brings is that LED lamp increase luminosity provides the foundation, as much as possible abundant lamp source can be installed on the outer peripheral face of heat-dissipating cylinder and not need to worry heat dissipation problem, and obtain powerful lighting effect, this is because when original radiating effect is limited, the installation in lamp source is subject to a definite limitation, the invention solves this problem, therefore, while lighting effect can being increased in certain area, the installation quantity of light fixture is reduced.
The present invention can be specially further:
Lamp holder upper cover is a kind of tepee structure, circular cone inclined-plane is evenly distributed with multiple strip through hole, and each strip through hole all distributes along the generatrix direction of circular cone.
The strip through hole that lamp holder covers can be communicated with the external world, makes fan can obtain air stream by this strip through hole from the external world like this, thus is that heat-dissipating cylinder drives heat by fan to wind.Lamp holder upper cover now as the bonnet of fan, as fan air intake passage.
Also include a dividing plate, it is installed between lamp holder upper cover and fixed head; Dividing plate is cross section H type structure, by last week along, next week edge and annular slab form, described annular slab is annular configuration, inner ring circle is adaptive with fan size, fan can be communicated to lamp holder upper cover by this inner ring circle, last week, next week was along the outer peripheral face being then connected to fixed head along the inner side being connected to lamp holder upper cover; Next week edge outer peripheral face on be laterally evenly distributed with multiple strip groove, fixed head is then provided with multiple hole that can be communicated to this strip groove.
Described strip groove is also be communicated with the external world, and dividing plate provides an exhaust passage by this strip groove, namely from lampshade inner chamber to the hole of fixed head, to the space between fixed head and dividing plate, is communicated to the external world finally by strip groove.Form one thus from lamp holder upper cover air intake, the air channel of dividing plate air-out.This is a kind of exhaust way adopting fan cooling, in addition, directly can also set out air port on lampshade, at lampshade side or top.Above-mentioned dividing plate air-out is preferably mode, and it can make air stream in heat-dissipating cylinder and lampshade, form convection current fully, fully to take away heat, reaches best radiating effect.
Described heat-dissipating cylinder includes cylindrical tube and is distributed in cylindrical shell outer peripheral face and " doing " font strip slot installed vertically, " do " center-pole of font strip slot perpendicular to cylindrical shell outer peripheral face, form lamp pearl plate slot between two horizontal strokes, between bottom rail and cylindrical shell, then form striped spatial.
Like this, LED lamp adopts multiple pencil-shape lamp pearl plate, and each lamp pearl plate can be plugged on the lamp pearl plate slot of adjacent two " doing " font strip slot, and between lamp pearl plate and cylindrical shell is described striped spatial.Described striped spatial can as ventilating duct, under the effect of the strong convection air provided at fan, for lamp pearl plate provides a good heat dissipation channel, improves radiating effect further.
Heat-dissipating cylinder can also be specially further:
In the inner chamber of heat-dissipating cylinder, have multiple strip fin along inner peripheral surface axial distribution, by one is long and the other is short, rule is evenly arranged on inner peripheral surface.
When fan is dried to heat-dissipating cylinder inner chamber, described fin can increase area of dissipation, simultaneously, because multiple fin is by the little space of compartition growth bar shaped near the inner peripheral surface of heat-dissipating cylinder, be conducive to improving wind speed, add strong convection, thus improve radiating effect further.
In sum, the invention provides a kind of LED lamp fan heat sink, mini-fan is used in LED lamp, thus provide larger cross-ventilation for LED lamp, make heat-dissipating cylinder obtain good radiating effect; Provide the foundation for LED lamp increases illumination effect further.
