Abstract
The utility model discloses an LED (light emitting diode) streetlamp which is mainly used for solving the problems that an existing LED streetlamp power supply has large induction heating value and large volume. The LED streetlamp comprises an LED light source, an LED power supply, a streetlamp shell and a streetlamp cover, wherein the LED power supply comprises a circuit board, a power supply box body and a power supply box cover. Through the LED streetlamp disclosed by the utility model, the LED power supply utilizes thin wires with the diameters smaller than 0.1mm, simultaneously insulating heat-conduction elastic pads are additionally arranged at two ends of a coil, and the LED streetlamp is fixed by utilizing a fixing press sheet with an annular flange, thus the effective area is increased, the volume of an inductor is reduced, and the volume of the power supply can be reduced to 1/5 of that of an original power supply.
Description
Technical field
The present invention relates to a kind of LED street lamp, belong to the LED lighting field.
Background technology
What high-power LED street lamp was different with conventional high-pressure mercury lamp street lamp is; The efficient white light-emitting diodes that the light source of high-power LED street lamp adopts low-voltage DC supply, synthesized by GaN based power type blue-ray LED and yellow fluorescent powder; Have efficient, safety, energy-saving and environmental protection, distinct advantages such as the life-span is long, response speed is fast, colour rendering index height, can be widely used in city illumination.High-power LED street lamp effectively reduces windage and weight, alleviates the load of lamp stand, strengthens safety coefficient.
Simultaneously, the inductance in the existing LED power supply generally takes thick line to twine (the line footpath is generally greater than 1mm), can cause the Kelvin effect of inductance to increase like this, and the inductance heating is big; In order to address this problem, the technical staff adopts the mode of dwindling the line footpath, but after dwindling the line footpath, fine rule is difficult fixing after winding, even can line pressure is disconnected.
Summary of the invention
The present invention provides a kind of LED street lamp, and the inductance caloric value that has mainly solved existing LED road lamp power supply is big, bulky problem.
Concrete technical solution of the present invention is following:
This LED street lamp; Comprise led light source, LED power supply, street lamp housing and street lamp lampshade; Said street lamp lampshade is arranged at the led light source outside and is connected with street lamp housing light source side; Street lamp housing dorsal part is provided with heat abstractor, and the centre of heat abstractor is provided with groove, and the shape and the street lamp post of groove cross section are suitable; Said street lamp housing dorsal part also is provided with pressing plate, and the cavity that forms between pressing plate and the groove is used to insert street lamp post, and pressing plate is fixedly connected with the street lamp housing through locking device; Said pressing plate is provided with at least one lightening hole; Doing flange around the lightening hole handles; Said LED power supply comprises wiring board, power supply box body and power supply lid, and said wiring board is fixedly set in the power supply box body, and said power supply box body is " U " type or " L " type; Comprise power pack body sidewall and power supply box plate, wiring board is fixedly set on the power supply box plate; Said power pack body sidewall is provided with inductance, and inductance is electrically connected with wiring board; Said inductance is through the fine rule coiling of diameter less than 0.01mm; Said inductance is fixed on the power pack body sidewall through screw; Be provided with the insulating radiation elastomeric pad between said inductance one side and the power pack body sidewall; Said 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.
The invention has the advantages that:
LED street lamp provided by the invention; Its power supply has adopted the fine rule of diameter less than 0.1mm; Adopt the insulating heat-conductive cushion to be carried in the coil two ends simultaneously, with having the fixedly compressing tablet that ring-type turns over time it has been fixed again, increased effective area; Dwindle the volume of inductance, can power volume have been reduced to original 1/5.
