Abstract
The invention discloses a light-emitting diode (LED) street lamp, and the LED street lamp mainly solves the problems that a power supply of an existing LED street lamp is large in heating value of an inductor and large in size. The LED street lamp comprises an LED light source, an LED power supply, a street lamp shell and a street lamp lampshade, and the LED power supply comprises a circuit board, a power supply box body and a power supply box cap. According to the LED street lamp, fine lines with diameter smaller than 0.1 mm are adopted by the power supply of the LED street lamp, at the same time insulated heat-conductive elastic cushions are adopted to be arranged at two ends of a coil, then the coil is fixed by fixing pressing pieces with annular flangings effective area is increased, size of the inductor is reduced, and size of the power supply is reduced to one fifth of the original size of the 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 from 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 the particular advantages such as efficient, safety, energy-saving and environmental protection, life-span length, fast response time, 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 existing LED power supply 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.
Summary of the invention
The invention provides a kind of LED street lamp, the inductance caloric value that has mainly solved existing LED road lamp power supply is large, bulky problem.
Concrete technical solution of the present invention is as follows:
This LED street lamp, 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, doing flange around lightening hole processes, described LED power supply comprises wiring board, power supply box body and power supply lid, described wiring board is fixedly installed in the power supply box body, described 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; Described inductance is fixed on the power pack body sidewall by screw, be provided with the insulating radiation elastomeric pad between described inductance one side and power pack body sidewall, described 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 acquisition 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, power volume can be down to original 1/5.
