Abstract
The invention provides a heat-dissipating light-emitting diode (LED) street lamp which mainly solves the problems that an existing heat-dissipating LED street lamp is low in connecting strength, poor in head dissipation performance and unsafe in utilization. The heat-dissipating LED street lamp comprises an LED light source, an LED power source, a street lamp shell body and a street lamp lampshade, wherein the street lamp lampshade is arranged on the outer side of the LED light source and connected with the street lamp shell body arranged at the side of the LED light source, a heat dissipating device is arranged on the back side of the street lamp shell body, a groove is formed in the middle of the heat dissipating device, and the shape of the cross section of the groove is matched with a street lamp pole. The LED power source comprises a circuit board, a power source box body and a power source box cover. The heat-dissipating LED street lamp and the light source of the heat-dissipating LED street lamp have the advantages of being uniform in heat dissipation of the power source and high in intensity.
Description
Technical field
The present invention relates to a kind of heat dissipation LED road lamp, belong to the LED lighting field.
Background technology
What high-power heat-dissipation 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 heat-dissipation 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 heat-dissipation LED street lamp effectively reduces windage and weight, alleviates the load of lamp stand, strengthens safety coefficient.
Due to high-power heat-dissipation LED street lamp when work caloric value large, therefore need the larger heat abstractor of assembling to satisfy its heat radiation requirement, cause like this increase of himself weight; Existing high-power heat-dissipation LED street lamp all arranges jockey by the street lamp casing side and is connected with the lamp stand end, and the intensity of this mode is lower, and long-term outwork may cause street lamp directly to come off from lamp stand, and what cause the accident frees.
The existing power supply box body 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 heat dissipation LED road lamp, mainly solved existing LED street lamp and the power supply bonding strength is low, heat dispersion is poor, use unsafe problem.
Concrete technical solution of the present invention is as follows:
This heat dissipation LED road 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 heat abstractor is comprised of equally distributed fin, comprise subzero temperature radiating part and streamline radiating part, described subzero temperature radiating part is arranged on the subzero temperature radiated rib group on the street lamp casing short transverse, and the streamline radiating part is arranged on the streamline radiated rib group on the street lamp casing width; 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, comprises power pack body sidewall and power supply box plate, and wiring board is fixedly installed on the power supply box plate; 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:
Heat dissipation LED road lamp provided by the invention, 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.
