Abstract
The invention provides a light-emitting diode (LED) street lamp with a protective pendant chain, and mainly solves the problems that a power tube of an existing LED street lamp power supply is poor in heat dispersion, and a pin of the existing LED street lamp power supply is large in stress. The LED street lamp with the protective pendant chain comprises an LED light source, an LED power supply, a street lamp shell and a street lamp shade. The street lamp shade is arranged outside the LED light source and is connected the light source side of the street lamp shell. The back side of the street lamp shell is provided with a cooling device, and a groove is formed in the middle of the cooling device. The shape of the cross section of the groove is adaptive to the shape of a lamp pole of the street lamp. The LED power supply comprises a circuit board, a power pack body and power pack cover. The circuit board is fixedly arranged in the power pack body, so that not only is the problem of heat dissipation solved, but also the problem of the stress of a pin is solved.
Description
Technical field
The present invention relates to a kind of LED street lamp with pendant chains, belong to the LED lighting field.
Background technology
High-power with the LED street lamp of pendant chains different from conventional high-pressure mercury lamp street lamp be, the efficient white light-emitting diodes that the light source of high-power LED street lamp with pendant chains 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 with pendant chains effectively reduces windage and weight, alleviates the load of lamp stand, strengthens safety coefficient.
The power tube of existing LED power supply 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.
Summary of the invention
The invention provides a kind of LED street lamp with pendant chains, mainly solved the problem that the power tube heat dispersion is poor, pin stress is large of existing LED road lamp power supply.
Concrete technical solution of the present invention is as follows:
This is with the LED street 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; Described LED power supply, comprise wiring board, power supply box body and power supply lid, above-mentioned wiring board is fixedly installed in the power supply box body, and 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; Above-mentioned power tube is electrically connected to wiring board, and power tube is fixedly installed on the power pack body sidewall.
The invention has the advantages that:
LED street lamp with pendant chains, because its power tube with power supply 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.
