According to the photoelectricity separation concave type LED pendent lamp, an LED power supply comprises a circuit board, a power supply box and a power supply box cover, the circuit board is fixedly arranged in the power supply box, an inductor is arranged on a side wall of the power supply box, the inductor is electrically connected with the circuit board, and a power tube is fixedly arranged on the side wall of the power supply box. According to the photoelectricity separation concave type LED pendent lamp, a fine wire with a diameter smaller than 0.1mm is used and insulation heat conduction elastic cushions are loaded at two ends of a coil, so that effective areas are increased, the size of the inductor is reduced, and the problem of the stresses of the pins are solved.
Description
Technical field
The present invention relates to a kind of fluted body LED pendent lamp of photodetachment, belong to the LED lighting field.
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 LED pendent lamp 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 power tube of existing LED pendent lamp power supply generally is set directly on the wiring board, causes heat comparatively concentrated like this, 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 the stress of pin like this, and long-term the use is prone to cause potential safety hazard.
Summary of the invention
The present invention provides a kind of fluted body LED pendent lamp of photodetachment, and the inductance caloric value that has mainly solved existing pendent lamp power supply is big, and volume is big, and the problem that the power tube heat dispersion is poor, pin stress is big.
Technical solution of the present invention is following:
The fluted body LED pendent lamp of this photodetachment comprises led light source, LED power supply, pendent lamp housing and canopy, and said canopy is arranged at the led light source outside and is connected with pendent lamp housing light source side, and said pendent lamp housing dorsal part is provided with heat abstractor; Said led light source is two, and two led light sources are symmetricly set in pendent lamp housing light source side; Said LED power supply is arranged in the heat abstractor of pendent lamp housing dorsal part; In the centre at the back side, position, two led light source positions and do not overlap with led light source; Said pendent lamp housing dorsal part is provided with heat abstractor; The centre of heat abstractor is provided with groove, and the width of groove is 1/3～1/4 of a fin width, and the degree of depth of groove is 1/2～9/10 of a fin maximum height; 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 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 power tube is electrically connected with wiring board, and power tube is fixedly set on the power pack body sidewall; 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 power tube is electrically connected with wiring board, and power tube is fixedly set on the power pack body sidewall.
The invention has the advantages that:
The power supply of the fluted body LED pendent lamp of photodetachment of the present invention 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.The present invention adopts power tube 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 processed, and power tube is completely fixed and be fitted on the power pack body sidewall; Promptly solve heat dissipation problem, solved the stress problem of pin again.
