The utility model content
The purpose of this utility model is that a kind of water resistance is good in order to provide, good heat dissipation effect, the reliable split type LED street lamp of connection.
For achieving the above object, a kind of split type LED street lamp comprises first heat abstractor and second heat abstractor; Described first heat abstractor is provided with substrate, and substrate is provided with the LED lamp, and what be positioned at substrate on first heat abstractor is provided with sealing strip all around, and sealing strip is provided with lampshade; Be provided with spatial accommodation in described second heat abstractor, be provided with power supply driver in the spatial accommodation, second heat abstractor is provided with sealing strip; Also be provided with cover plate on described second heat abstractor; Described first heat abstractor and second heat abstractor are connected in series by securing member; Be provided with first threading via hole in first heat abstractor, be provided with second threading via hole in first heat abstractor, described first threading via hole and second threading via hole communicate.
Said structure, the heat that the LED lamp produces is by the heat radiation of first heat abstractor, the heat that power supply driver produces is by the heat radiation of second heat abstractor, and first heat abstractor and second heat abstractor are connected in series, first heat abstractor and second heat abstractor do not disturb when heat radiation mutually, therefore, good heat dissipation effect; Owing on first heat abstractor, be provided with sealing strip, on sealing strip, be provided with lampshade, like this, LED lamp and substrate are sealed in the space that is surrounded by first heat abstractor, sealing strip and lampshade, owing on second heat abstractor, be provided with sealing strip and cover plate, power supply driver is sealed in the spatial accommodation like this, and owing to be provided with first threading via hole and second threading via hole, the circuit that connects power supply driver and LED lamp passes and does not contact with the external world with second threading via hole from first threading via hole, therefore, the water resistance of whole LED street lamp is good; Because first heat abstractor is connected by securing member with second heat abstractor, therefore, the fastness of connection is good.
As improvement, described first heat abstractor is provided with overlap, and described cover plate overlap joint is fixed on the overlap.This structure, first heat abstractor not only is connected by securing member with second heat abstractor, and cover plate couples together first heat abstractor and second heat abstractor, therefore, has strengthened the reliability and the fastness that connect.
As improvement, the surface that described first heat abstractor is positioned at installation base plate is provided with Wire channel in building, and described Wire channel in building extends on the overlap; Overlap is positioned at the Wire channel in building place and is provided with sealing gasket.Wire channel in building is set is in order to pass link tester in first threading via hole and cross first heat abstractor and be connected on the LED lamp; Wire channel in building extends to overlap can shorten the distance of the edge of first heat abstractor to Wire channel in building, is convenient to that the circuit in first threading via hole is passed Wire channel in building and is connected with LED, has made things convenient for to produce and make.
As improvement, described first heat abstractor comprises the substrate installing plate and first fin, and first fin is installed on the substrate installing plate, and the corresponding position of screw hole of described first fin and installation base plate is provided with radiating ribs.For better heat radiation, the substrate heat sink is made thinlyyer, and radiating ribs is set, and can strengthen substrate and on the substrate installing plate fastness is installed.
As improvement, be coated with one deck heat radiation enamelled coating on the described second heat abstractor outer surface.The heat radiation enamelled coating is set can plays thermolysis, can also prevent to wear out, and attractive in appearance.
As improvement; cover plate on second heat abstractor is provided with the water proof and dust proof ventilated membrane; the negative effect that the pressure reduction that the water proof and dust proof ventilated membrane can protect lamp housing to avoid causing owing to variations in temperature effectively brings to lamp housing is because the water proof and dust proof ventilated membrane can make lamp housing pressure of both sides inside and outside the balance lamp housing when variations in temperature.The water proof and dust proof ventilated membrane stops leakage by the pressure of both sides inside and outside the continuous balance lamp housing, the stress that further reduces sealing strip thus and born, and will tie the mist dewfall and reduce to minimum.In addition, the water proof and dust proof grade of water proof and dust proof ventilated membrane own is to IP69K.
