The utility model discloses not only having improved the lamps and lanterns installation effectiveness, having avoided the driver to expose the problem that the life that brings shortens, increased the sealed face of vertically contacting simultaneously on the sealed basis of horizontal contact electricity between the cover body and shroud again, the drop of water and dust be not from following the vertically contacting face entering intracavity that rises after the horizontal contact face gets into to the waterproof dustproof effect of panel light has been improved.

Description

Built-in drive water proof and dust proof panel light

Technical field

This utility model relates to illuminating lamp, particularly with regard to built-in drive water proof and dust proof panel light.

Background technology

Along with rapid economic development and people's living standard improve constantly, power consumption surges rapidly and with more and more nervous. It is known that compared with existing electric filament lamp, daylight lamp, LED has the advantage that luminous intensity height, life-span length and power consumption are few, LED has been widely used as illuminating lamp, Landscape Lamp, advertising lamp and street lamp etc., its most applicable real electricity, it is possible to be suitable for solar energy and wind Can generating, therefore popularize in an all-round way and use LED, both there is using effect and improved, again can the advantage of saves energy in a large number.At present LED street lamp is roughly divided into panel type (square and circular) street lamp and spherical street lamp (Projecting Lamp), and spherical street lamp mostly uses unlimited Formula sheet metal dispels the heat, and panel type street lamp is lamp bead to be fixed on aluminium base by tin cream and chip mounter, further according to various roads Lamp watt level specification is cut into the aluminium base of different lamp bead quantity and distribution shape and assembles, and panel type street lamp is mostly logical Cross aluminium base and radiator dispels the heat.But existing Projecting Lamp in use there is problems: one is supporting with panel light Driver is overall package and sale, and on existing market, whether lamp damages or drive corruption, during exchange must be Entirety carries out exchanging, and existing panel light driver is attached to outside lamp body, and driver will additionally be arranged greatly, is not easy to peace Dress, is in for a long time in air simultaneously and is also easy to damage；Two is that the sealing between cover body and cover cap only connects by its narrower level Contacting surface (contact ring) seals, and owing to deformation effect and process technology limit, there is gap, the globule and dust and hold between contact surface Easily penetrate in cavity from the gap of contact surface, affect the serviceability of lamp.

Utility model content

For the problem in the presence of above-mentioned prior art, the utility model proposes a kind of driver and be arranged on lamp body In, and use overall plastic heat sink to dispel the heat, easier for installation, driver is longer for service life, and the built-in of better tightness drives Dynamic device water proof and dust proof panel light.

The technical problems to be solved in the utility model is adopted the technical scheme that: described built-in drive water proof and dust proof face Plate lamp includes cylindrical circular cover body and fixes the cover cap matched with cover body, and the round boss side in the middle of described cover body is spaced It is provided with light pearl, round boss bottom surface is disposed with diffuser plate, light guide plate, reflecting paper and plastic heat radiation plate from bottom to up, It is provided with groove in the middle of described cover cap, in described groove, is fixedly installed driver, described groove is provided with cover plate, described cover Inner ring body friction tight with cover cap medial surface it is provided with on body.

Driver is fixedly installed in the groove on cover cap by this utility model, makes driver be formed whole with cover body and cover cap Body, thus wire can be made directly to be joined directly together with power supply, not only increase lamp installation efficiency, it is to avoid driver exposes and carried The problem that the service life come shortens, adds again vertical simultaneously on the basis of the flat contact face seal between cover body and cover cap Contact sealing surface, the globule and dust will not ascend in cavity from perpendicular contact face after horizontal contact face enters, thus carry The high water proof and dust proof effect of panel light.
