Abstract

The utility model provides a dodging type light-emitting diode (LED) pendent lamp with an installation board and a pendant chain and mainly solves problems that existing inductors are large in heat productivities and in sizes and poor in radiating performances, and can not work under hot and humid environments. An LED power supply of the dodging type LED pendent lamp with the installation board and the pendant chain comprises a circuit board, a power supply box and a power supply box cover, the power supply box is in a U shape or in an L shape, an inductor is arranged on a side wall of the power supply box, and the inductor is electrically connected with the circuit board, and the inductor is formed by the winding of a fine wire with the diameter smaller than 0.01mm; and a vacancy unit is independently perpendicular to the circuit board. According to the dodging type LED pendent lamp with the installation board and the pendant chain, effective areas are increased, and the size of an inductor is reduced by 1/5 of an original size; and the vacancy unit can be independently changed, and when the vacancy unit is vertically arranged, air channels can be formed, the circulation of air currents is faciliated so that heat can be taken away, and the radiating effects are further improved.

Description

A kind of even light type LED pendent lamp with installing plate and chain sling

Technical field

The present invention relates to a kind of even light type LED pendent lamp, belong to the LED lighting field with installing plate and chain sling.

Background technology

The LED illumination promptly is a led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, in semiconductor, through carrier compound energy of emitting surplus takes place and causes photo emissions, 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.

Pendent lamp generally must be fixed with chain sling, suspension hook hanging, and the upper end is connected with the built-in fitting of building, and pendent lamp light requires can not hinder people's normal line of sight, also can not hinder the sight line that the people hopes mutually, or make us feeling dazzling.It is appropriate that the canopy Material Selection is wanted, and do not adopt and can generation make us uncomfortable dazzle.When the lampshade moulding was complicated, in the environment of moist, many dirt, light fixture got rusty easily, falls lacquer, and lampshade covers dirt light can be day by day dim, did not often maintain, cleaned, and illumination one annual reduces approximately 30 percent according to statistics, does not go out several years, and pendent lamp is with dim nothings brilliance.

The inductance of existing power supply generally takes thick line to twine (the line footpath is generally greater than 1mm), can cause the Kelvin effect of inductance to increase like this, and the inductance heating is big; In order to address this problem, the technical staff adopts the mode of dwindling the line footpath, but after dwindling the line footpath, fine rule is difficult fixing after winding, even can line pressure is disconnected.

The vacant unit of existing power supply is generally positioned on the wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the operate as normal of hot and humid environment.

Summary of the invention

The present invention provides a kind of even light type LED pendent lamp with installing plate and chain sling, and the inductance caloric value that has mainly solved existing pendent lamp power supply is big, and volume is big, and heat dispersion is poor, the problem of working in the hot and humid environment again.

Technical solution of the present invention is following:

The even light type LED pendent lamp of this band installing plate and chain sling; Comprise led light source, LED power supply, pendent lamp housing and canopy; Said canopy is arranged at the led light source outside and is connected with pendent lamp housing light source side; Be connected with four chain slings on the said pendent lamp housing dorsal part, the chain sling other end is connected with installing plate; The line of said four chain slings and pendent lamp housing tie point is a rectangle, and this rectangle is similar with the pendent lamp lamp housing; Each chain sling connects through the chain sling connecting ring that is arranged on the pendent lamp housing dorsal part, and the even light type LED pendent lamp of said band installing plate and chain sling is fixed on the installation position through installing plate, and chain sling is connected with installing plate; Described installing plate is provided with the chain sling installing hole identical with the chain sling number; Installing plate is similar with the shape of pendent lamp housing; Also be provided with on the installing plate and be mounted a jockey that is connected; The even light type LED pendent lamp of said band installing plate and chain sling also comprises speculum and reflector, and speculum and reflector are positioned at 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, and led light source is arranged on the central point of reflecting surface and reflector; Said LED power supply; Comprise wiring board, power supply box body and power supply lid, said wiring board is fixedly set in the power supply box body, and said power supply box body is " U " type or " L " type; Comprise power pack body sidewall and power supply box plate, wiring board is fixedly set on the power supply box plate; Said power pack body sidewall is provided with inductance, and inductance is electrically connected with wiring board; Said inductance is through the fine rule coiling of diameter less than 0.01mm; Said inductance is fixed on the power pack body sidewall through screw; Be provided with the insulating radiation elastomeric pad between said inductance one side and the power pack body sidewall; Said 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; Said vacant unit independently is vertically installed on the wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃.

The invention has the advantages that:

The power supply of the even light type LED pendent lamp of this band installing plate and chain sling has adopted the fine rule of diameter less than 0.1mm; Adopted the insulating heat-conductive cushion to be carried in the coil two ends simultaneously; With having the fixedly compressing tablet that ring-type turns over time it is fixed again; Increase effective area, dwindled the volume of inductance, can volume have been reduced to original 1/5; Take mounting means is in the circuit board erect in vacant unit, easy heat radiation is set like this, can carry out independent replacing, be applicable to hot and humid environment vacant unit, can be at-40 ℃～100 ℃, operate as normal in 90% humidity environment; When humidity in the power supply was big, 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.
