Abstract
The utility model provides a radiating light-emitting diode (LED) street lamp which mainly solves problems that the existing LED street lamp is low in connection strength, poor in radiating performance and not safe to use. The radiating LED street lamp comprises an LED light source, an LED power source, a street lamp casing and a street lamp shade, wherein the street lamp shade is arranged on the outer side of the LED light source and connected with the light source side of the street lamp casing, a radiating device is arranged on the back side of the street lamp casing, a groove is arranged in the middle of the radiating device, and the shape of the cross section of the groove is matched with that of a street lamp post. The LED power source comprises a circuit board, a power source box body and a power source box cover. The radiating LED street lamp and the power source of the radiating LED street lamp are uniform in radiating and high in strength.
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 road 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 heat dissipation LED road 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 heat dissipation LED road lamp effectively reduces windage and weight, alleviates the load of lamp stand, strengthens safety coefficient.
Since high-power heat dissipation LED road lamp when work caloric value big, therefore need the bigger heat abstractor of assembling to satisfy its heat radiation requirement, cause the increase of himself weight like this; Existing high-power heat dissipation LED road lamp all is provided with jockey through the street lamp side and is connected with the lamp stand end, and the intensity of this mode is lower, and long-term outwork possibly 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 the intensity of power supply box body lower like this, and the each several part heat dispersion is inconsistent, is unfavorable for heat radiation; Simultaneously, does not generally handle existing power supply box body bottom, and it is not tight to cause power supply bottom and mounted piece to be fitted, and is unfavorable for the heat conduction.
Summary of the invention
The present invention provides a kind of heat dissipation LED road lamp, has 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 following:
This heat dissipation LED road 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 heat abstractor is made up 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 housing short transverse, and the streamline radiating part is arranged on the streamline radiated rib group on the street lamp housing width; Said LED power supply comprises wiring board, power supply box body and power supply lid; Said wiring board is fixedly set in the power supply box body; Said 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 set on the power supply box plate; Said power supply box plate away from circuit board one side be mounted the position and fit the insulating heat-conductive box that power supply box plate and power pack body sidewall are formed in one fully.
The invention has the advantages that:
Heat dissipation LED road lamp provided by the invention, its power supply box body is an integral piece, and heat radiation is even, and intensity is high; Simultaneously, the box body back is handled, make its with mounted piece between contact closely, be beneficial to the heat conduction.
