Abstract

The invention provides a uniform light cooling type light-emitting diode (LED) pendant lamp with chains and a groove, and mainly solves the problems that an LED power supply of an existing pendant lamp is poor in heat dispersion, not capable of working in high-temperature high-humidity environment, and poor in heat transfer property and strength. The uniform light cooling type LED pendant lamp with the chains and the groove is provided with four pendant chains, and further comprises a reflecting mirror and a reflecting cup. A cooling device is composed of fins which are evenly distributed and comprises a negative temperature cooling part and a streamline cooling part. The LED power supply comprises a circuit board, a power pack body and a power pack cover. In the uniform light cooling type LED pendant lamp with the chains and the groove, the installation method that a vacant unit is erected on a circuit board is adopted, so that the vacant unit can be changed independently and is suitable for the high-temperature high-humidity environment. In addition, the erect arrangement can form an air channel, so that heat can be brought away though airflow circulation conveniently and the heat dissipation effect is further improved. The back of the power pack body is processed, so that the back of the power pack body is closely contacted with an installed part, so that heat conduction is convenient.

Description

A kind of even smooth heat radiating LED ceiling lamp with chain sling and groove

Technical field

The present invention relates to a kind of even smooth heat radiating LED ceiling lamp with chain sling and groove, belong to the LED lighting field.

Background technology

The LED illumination is namely LED lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, by carrier, compound energy of emitting surplus occurs and cause photo emissions in semiconductor, directly sends red, yellow, blue, green, blue or green, orange, purple, white light.The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.

The vacant unit of the LED power supply of existing even smooth heat radiating LED ceiling lamp with chain sling and groove is generally positioned on wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the normal operation of hot and humid environment; Simultaneously, the 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 even smooth heat radiating LED ceiling lamp with chain sling and groove, mainly solved the LED power supply heat sinking poor performance of existing pendent lamp, work in hot and humid environment again; The problem that heat-conductive characteristic and intensity are relatively poor.

Technical solution of the present invention is as follows:

this is with the even smooth heat radiating LED ceiling lamp of chain sling and groove, comprise LED light source, LED power supply, pendent lamp housing and canopy, described canopy is connected with pendent lamp housing light source side outside being arranged at LED light source, be connected with four chain slings on described pendent lamp housing dorsal part, the chain sling other end is connected with installing plate, the line of described four chain slings and pendent lamp housing tie point is rectangle, and this rectangle is similar to the pendent lamp lamp housing, each chain sling connects by the chain sling connecting ring that is arranged on pendent lamp housing dorsal part, described even smooth heat radiating LED ceiling lamp with chain sling and groove also comprises speculum and reflector, speculum and reflector are located in canopy, are fixedly connected with the light source side of pendent lamp housing, reflector is arranged at reflecting surface one side of speculum and overlaps with the reflector central point, LED light source is arranged on the central point of reflecting surface and reflector, be provided with heat abstractor on described pendent lamp housing dorsal part, 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 pendent lamp housing short transverse, the streamline radiating part is arranged on the streamline radiated rib group on pendent lamp housing width, the centre of described heat abstractor is provided with groove, the width of groove is 1/3～1/4 of fin width, the degree of depth of groove is 1/2～9/10 of fin maximum height, 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 vacant unit independently is vertically installed on wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃, 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:

This power supply with the even smooth heat radiating LED ceiling lamp of chain sling and groove is taked vacant unit setting mounting means in the circuit board, easy heat radiation is set like this, can carries out independent replacing to vacant unit, be applicable to hot and humid environment, can at-40 ℃～100 ℃, work in 90% humidity environment; When in power supply, humidity was larger, dew can flow down along the wiring board of erectting; Simultaneously, erect setting and can form the air channel, be beneficial to airflow and take away heat, further improved radiating effect; The 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.
