Description
Technical field
The present invention relates to a kind of lighting device, relate in particular to a kind of LED lamp.
Background technology
Traditional LED light fixture series LED light emitting source particle that is used for outdoor lighting lamp is being welded on the aluminium base of the regularity of distribution together simultaneously, and aluminium base is fixedly mounted on the lamp body radiator through screw, all is to use bolt each other.Circuit and aluminium base be welded to connect or be connected with a miniature connector.Or then the LED particle has adopted modularization; Adopt the high-power LED particle to be distributed in separately on the fritter aluminium base,, but aspect the safeguarding of actual light fixture, deficiency is arranged again through welding or be connected on the lamp body radiating element with a small-sized connector; Need take light fixture apart keeps in repair separately each parts; Can't directly replace led light source, have only depot repair or the on-site maintenance of sending someone, maintenance cost is higher.
Improved LED light fixture is arranged again; Disclose a kind of band screw socket LED lamp for X number like Chinese patent CN201010556692., comprised lens, reflector, LED aluminium base, radiator, plastic feet, driving power and lamp holder, the radiator neck is provided with the heat-conducting plate of integral type; Lens, reflector and LED aluminium base are located in the cup die cavity of radiator and fix through back-up ring; The bottom and the plastic feet of radiator are connected to form cavity, and driving power is located in the cavity, and the bottom of plastic feet is connected with lamp holder; Bottom at plastic feet is provided with bayonet socket, is provided with the unwrapping wire groove below the bayonet socket; On heat-conducting plate, be provided with locating slot, the LED aluminium base is located on the locating slot, and heat-conducting plate and radiator inwall junction are provided with the screw thread eccentric orfice.Though the LED lamp that this patent designed maintains easily, its radiating effect is not good, and especially the heat of LED aluminium base in the cup die cavity can not discharge well, causes internal heat to be gathered, and influences the service life of LED.
Summary of the invention
In order to solve problem related in the background technology, the present invention provides a kind of LED lamp and LED light fixture.
The present invention provides a kind of LED lamp, comprises aluminium base and lamp bracket, and lamp bracket is provided with a base plate; Aluminium base is fixed on the base plate, also is provided with a cavity in the lamp bracket, and the wall of cavity is provided with and the vertical interior fin in base plate plane, place; The base plate periphery is provided with lampshade, is provided with outer fin between lampshade and the lamp bracket, interior fin and outer fin interlaced arrangement; Be buckled with diffuser on the lampshade, be fixed with an attachment plug on the lamp bracket.
Aluminium base is provided with led chip; Thereby heat mainly generates from aluminium base, and aluminium base is fixed on the base plate, thus in fin increased the contact area with aluminium base effectively; Make heat from aluminium base, derived quickly; And distribute heat through outer fin, and interior fin and outer fin interlaced arrangement help heat and distribute faster.Outer fin is arranged between lampshade and the lamp bracket, can strengthen the bonding strength between lampshade and the lamp bracket simultaneously.
As a kind of preferred, attachment plug is screw type plug or buckle-type plug.
More convenient when adopting screw type plug or buckle-type plug to make installation and maintenance, need not by external tool, and the junction is not fragile.
As a kind of preferred, lampshade is provided with catching groove, and catching groove is provided with a bottom surface; With the bottom surface perpendicular be provided with a step surface, diffuser is fixed with supporting leg, the supporting leg cramp that is connected; The cramp elastic block piece that is connected is provided with an inclined-plane between elastic block piece on the elastic block piece and cramp.
When diffuser and lampshade were interlocked, elastic block piece and step surface propped up mutually, make that diffuser and lampshade are difficult for throwing off, and the inclined-plane that is positioned on the elastic block piece made when diffuser and lampshade are interlocked, and elastic block piece more is prone in the entering catching groove, ease of assembly.
As a kind of preferred, lampshade is provided with a seal groove, is provided with sealing ring in the seal groove.
Sealing ring is arranged on seal groove not only has protective action preferably, and make sealing ring be in one to be airtight environment relatively, it is aging that it is difficult for, and prolonged service life.
As a kind of preferred, aluminium base is through being bolted on the base plate.
The present invention also provides a kind of LED light fixture, comprises at least one LED lamp, and the LED lamp links to each other with socket through attachment plug; Socket links to each other with platform; The LED lamp is provided with rain cover outward, and rain cover comprises ceiling, side cover and base, is provided with admission space between base and the side cover; Be provided with out the headroom between ceiling and the side cover, admission space is greater than going out the headroom.
Extraneous air gets into from being provided with admission space between base and the side cover; And take away the heat on each LED lamp; Because of hot-air is lighter,, therefore formed effective convection current so go out from being provided with the space divergence of giving vent to anger between ceiling and the side cover easily; Make that the integral heat sink performance is preferable, and can stop the infiltration of rainwater.Admission space is greater than going out the headroom, makes that the low gas inlet of temperature is big, goes out that the headroom is little can accelerate the thermal current flow velocity, makes radiating effect more excellent.
As a kind of preferred, be provided with sealing ring between plug and the socket, sealing ring is arranged in the groove of plug and socket.
The coupling part of plug and socket is prone to get into foreign material such as dust, steam usually, and the protective action of sealing ring is preferable, can foreign material be blocked in the groove, makes it be difficult for getting into lamp interior, when safeguarding, only need clear up groove and get final product.
As a kind of preferred, base is embedded with the light-passing board that a light-transmitting materials is processed.
As a kind of preferred, be provided with support column between ceiling and the side cover, the side cover inlet wire pipe that is connected.
As a kind of preferred, the side cover is provided with air vent.
In sum, the present invention has the following advantages:
1, the present invention is provided with the interior fin and the outer fin of interlaced arrangement, strengthened radiating effect, and integral sealing effect is good, maintains easily.
2, the present invention also provides a kind of LED light fixture, and is provided with rain cover and admission space and goes out the headroom, can improve degree of protection and make better heat-radiation effect again.
