Abstract
The invention provides a dodging light-emitting diode (LED) street lamp with protective pedant chains. The dodging LED street lamp with the protective pedant chains mainly solves the problems that an inductor of an existing LED power supply is large in heating quantity and large in size, a power tube is bad in heat dispersion, and stress of a pin is big, heat conduction performance is bad, and strength is bad. The dodging LED street lamp with the protective pedant chains comprises an LED light source, an LED power supply, a street lamp shell body and a street lamp cover. The street lamp cover is arranged on the outer side of the LED light source and is connected with the light source side of the street lamp shell body. A heat dissipation device is arranged on the back side of the street lamp shell body, a groove is formed in the middle of the heat dissipation device, and the shape of the cross section of the groove fits in with a lamp street rod. Due to the adoption of the thin wires with diameters which are smaller than 0.01 millimeter, effective area is enlarged, and size of the inductor is reduced. Due to the fact that power tubes are arranged on the side wall of the power supply box body, not only a heat dissipation problem is solved, but also the problem of the stress of the pin is solved. The power supply box body is an integrated piece and is even in heat dissipation and high in intensity.

The inductance of the LED power supply of existing even light LED road lamp with pendant chains generally takes thick line to be wound around (wire diameter is generally greater than 1mm), can cause like this Kelvin effect of inductance to increase, and the inductance heating is large; In order to address this problem, the technical staff adopts the mode of dwindling wire diameter, but after dwindling wire diameter, fine rule is more difficult fixing after winding, even can line pressure is disconnected.
The power tube of the LED power supply of existing even light LED road lamp with pendant chains generally is set directly on wiring board, causes like this heat comparatively concentrated, is unfavorable for heat radiation; In order to address this problem, the technical staff adopts the set-up mode perpendicular to wiring board, but has increased like this stress of pin, and long-term use easily causes potential safety hazard.
The power supply box body of the LED power supply of existing even light LED road lamp with pendant chains is generally the split part, cause like this intensity of power supply box body lower, and the each several part heat dispersion is inconsistent, is unfavorable for heat radiation; Simultaneously, does not generally process existing power supply box body bottom, causes power supply bottom and mounted piece to be fitted not tight, is unfavorable for the heat conduction.
Summary of the invention
The invention provides a kind of even light LED road lamp with pendant chains, mainly solved existing LED road lamp power supply inductance caloric value large, volume is large; The power tube heat dispersion is poor, pin stress is large; The problem that heat-conductive characteristic and intensity are relatively poor.
Concrete technical solution of the present invention is as follows:
This is with the even light LED road lamp of pendant chains, comprise LED light source, LED power supply, street lamp casing and street lampshade, described street lampshade is connected with the street lamp casing light source side outside being arranged at LED light source, be provided with heat abstractor on the street lamp casing dorsal part, the centre of heat abstractor is provided with groove, and shape and the street lamp post of groove cross section are suitable; Described street lamp casing dorsal part also is provided with pressing plate, and the cavity that forms between pressing plate and groove is used for inserting street lamp post, and pressing plate is fixedly connected with street lamp casing by locking device; Be provided with at least one lightening hole on described pressing plate, do flange around lightening hole and process; The street lamp dorsal part also is provided with at least two root guard chain slings; This street lamp also comprises speculum and reflector, and speculum and reflector are located in street lampshade, is fixedly connected with the light source side of street lamp casing; Reflector is arranged at reflecting surface one side of speculum and overlaps with the reflector central point, and LED light source is arranged on the central point of reflecting surface and reflector; Described LED power supply, comprise wiring board, power supply box body and power supply lid, described wiring board is fixedly installed in the power supply box body, and the power supply box body is " U " type or " L " type, comprise power pack body sidewall and power supply box plate, wiring board is fixedly installed on the power supply box plate; Be provided with inductance on described power pack body sidewall, inductance is electrically connected to wiring board; Described inductance is by the fine rule coiling of diameter less than 0.01mm; Inductance is fixed on the power pack body sidewall by screw, be provided with the insulating radiation elastomeric pad between inductance one side and power pack body sidewall, the inductance opposite side is disposed with the insulating radiation elastomeric pad, fixedly compressing tablet and hold-down nut, fixedly compressing tablet is provided with the flange that is used to the screw guiding near the insulating radiation elastomeric pad; Described power tube is electrically connected to wiring board, and power tube is fixedly installed on the power pack body sidewall; Described power supply box plate away from circuit board one side be mounted the position and fit fully, the insulating heat-conductive box that power supply box plate and power pack body sidewall are formed in one.
The invention has the advantages that:
This power acquisition with the even light LED road lamp of the pendant chains fine rule of diameter less than 0.1mm, adopted simultaneously the insulating heat-conductive cushion to be carried in coil two ends, use again the fixedly compressing tablet that turns over time with ring-type that it is fixed, increased effective area, dwindled the volume of inductance, volume can be down to original 1/5.
This power acquisition with the even light LED road lamp of pendant chains is used power tube is arranged on the power pack body sidewall, and then pin is connected with wiring board, because the power pack body sidewall is that heat sink material is made, and power tube is completely fixed and be fitted on the power pack body sidewall, namely solve heat dissipation problem, solved again the stress problem of pin.
This is with the power supply of the even light LED road lamp of pendant chains, and its power supply box body is integrated part, and heat radiation is even, and intensity is high; Simultaneously, the box body back is processed, make its with mounted piece between contact closely, be beneficial to the heat conduction.
