In the time that diffuser and lampshade are interlocked, elastic block piece and step surface prop up mutually, make diffuser and lampshade be difficult for throwing off, and when being positioned at inclined-plane on elastic block piece diffuser and lampshade being interlocked, elastic block piece more easily enters in catching groove, ease of assembly.
Preferred as one, lampshade is provided with a seal groove, is provided with sealing ring in seal groove.
Sealing ring is arranged on to seal groove and not only there is good protective action, and make sealing ring relatively be airtight environment in one, it is difficult for aging, extended service life.
Preferred as one, aluminium base is bolted on base plate.
The present invention also provides a kind of LED light fixture, comprise at least one LED lamp, LED lamp is connected with socket by attachment plug, socket is connected with platform, LED lamp is provided with rain cover outward, and rain cover comprises ceiling, side cover and base, between base and side cover, is provided with admission space, between ceiling and side cover, be provided with out headroom, admission space is greater than headroom.
Extraneous air enters from being provided with admission space between base and side cover, and take away the heat on each LED lamp, because of hot-air lighter, therefore easily go out from being provided with the space divergence of giving vent to anger between ceiling and side cover, therefore formed effective convection current, make integral heat sink performance better, and can stop the infiltration of rainwater.Admission space is greater than headroom, makes temperature large compared with low gas inlet, goes out that headroom is little can accelerate thermal current flow velocity, makes radiating effect more excellent.
Preferred as one, between plug and socket, be provided with sealing ring, sealing ring is arranged in the groove of plug and socket.
The coupling part of plug and socket more easily enters the foreign material such as dust, steam conventionally, and the protective action of sealing ring is better, foreign material can be blocked in groove, makes it be difficult for entering lamp interior, only need clear up groove in the time safeguarding.
Preferred as one, base is embedded with the light-passing board that a light-transmitting materials is made.
Preferred as one, between ceiling and side cover, be provided with support column, the side cover inlet wire pipe that is connected.
Preferred as one, side cover is provided with air vent.
In sum, the present invention has the following advantages:
1, the present invention is provided with 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 headroom, can improve degree of protection and make again better heat-radiation effect.
