Abstract
The utility model provides a rotary LED (Light-Emitting Diode) floodlight with a protection pendant chain, which mainly solves the problems that the conventional LED light source has the defects of large inductance heat, large size, poor heat radiation property of a power tube, and large stress of a pin. The rotary LED floodlight with the protection pendant chain comprises an LED light source, an LED power source, a floodlight shell and a floodlight cover; the LED power source comprises a circuit board, a power source box body and a power source box cover; the circuit board is fixedly arranged in the power source box body; an inductor is arranged on a side wall of the power source box body; the inductor is electrically connected with the circuit board; the inductor is coiled by a thin wire with a diameter which is less than 0.01 mm; and a power pipe is fixedly arranged on the side wall of the power source box body. The rotary LED floodlight with the protection pendant chain uses the thin wire with the diameter which is less than 0.1 mm, and insulating heat conduction elastic pads are simultaneously loaded at both ends of a coil, so that the effective area is enlarged; the size of the inductor is reduced; and the stress problem of the pin can be solved.
Description
Technical field
The present invention relates to a kind of rotating LED floodlight, belong to the LED lighting field with the protection chain sling.
Background technology
Floodlight is a kind of spot light of uniform irradiation to all the winds, floodlight produces be the height diffusion, nondirectional light but not the light beam of clear-cut; Floodlight does not have electrode, is to lean on electromagnetic induction principle to combine with the fluorescence discharge principle and luminous, so there is not the inevitable assembly that limits the life-span in it; The shade that produces is soft and transparent, when being used for the object illumination, the speed that illumination weakens when throwing light on spotlight slowly many, even some illumination weakens very slow floodlight, looks similarly to be a light source that does not produce shade.
Existing inductance 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.
Existing power tube 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 rotating LED floodlight with the protection chain sling, and it is big mainly to have solved existing inductance caloric value, and volume is big; The problem that the power tube heat dispersion is poor, pin stress is big.
Concrete technical solution of the present invention is following:
A kind of rotating LED floodlight with the protection chain sling comprises led light source, LED power supply, floodlight housing and floodlight lampshade, and said floodlight lampshade is arranged at the led light source outside and is connected with floodlight housing light source side; The floodlight dorsal part is provided with fixed connection apparatus, and said fixed connection apparatus comprises firm banking and installing rack, and firm banking is fixedly connected with the floodlight dorsal part; And be provided with the rotation draw-in groove; Installing rack one end is connected with firm banking through the tightening device, and the other end is connected with mounting points, and the tightening device moves in draw-in groove; Said floodlight dorsal part also is provided with at least two root guard chain slings; Said LED power supply comprises wiring board, power supply box body and power supply lid, and 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 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 LED power supply of the rotating LED floodlight of this band protection 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.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.
