LED during as display or other lighting apparatus, need to carry out the constant current driving to it, avoids drive current to exceed maximum rating on the one hand, affects its reliability, obtains on the other hand the brightness requirement of expection, guarantees each LED brightness, colourity uniformity.The drive unit of existing LED lamp generally is placed on light fixture, by wire, with the circuit board of light fixture, be connected, cause that cylinder lamp structure is complicated, attractive in appearance not, the processing and manufacturing cost is high, production efficiency is low, light fixture in use simultaneously, the heat that drive unit produces can not dissipate in time, can affect the life-span of drive unit, thereby affect the service life of light fixture.
The technical problems to be solved in the utility model be to provide a kind of simple in structure, processing and fabricating efficiency is high, cost is low, drive unit is integrated on circuit board and be placed in the LED Down lamp of Down lamp inside.
The utility model content
In order to solve in above-mentioned prior art, drive unit is external is independent of the problem that cylinder lamp structure is complicated, attractive in appearance not, the processing and manufacturing cost is high, production efficiency is low, service life is short that light fixture causes, and the utility model adopts following technical scheme:
The utility model provides a kind of integral type to drive built-in LED Down lamp, comprise Down lamp body, transparent lamp shade, lampshade fixed cap, circuit board, LED lamp pearl array and LED drive unit, described Down lamp body comprises base plate and side wall surface, described side wall surface extends radially outwardly and forms circular carrier, described transparent lamp shade is arranged on carrier by described lampshade fixed cap, described LED lamp pearl array and described LED drive unit are arranged on described circuit board, and described circuit board is connected with described base plate with heat-conducting glue by screw.
As to improvement of the present utility model, described circuit board adopts aluminium base.
As to further improvement of the utility model, described base plate and side wall surface adopt the die casting aluminium one-shot forming, and on described side wall surface, with the louvre of heat sink and two symmetries, described base plate is provided with wiring hole.
As to further improvement of the utility model, the centre of described circuit board is provided with wire and connects hole.
As to further improvement of the utility model, the carrier of described side wall surface has notch, and described lampshade fixed cap is provided with the snap close corresponding with described notch.
