Abstract
The utility model provides an inductance type LED (Light Emitting Diode) power supply, which mainly solves the technical problems of the present inductor of high heating value and big volume. The inductance type LED power supply comprises a circuit board, a power supply box and a power supply box cover, wherein the circuit board is fixedly arranged in the power supply box; the power supply box is U-shaped or L-shaped and comprises a side wall of the power supply box and a base plate of the power supply box; the circuit board is fixedly arranged on the base plate of the power supply box; the inductor is arranged on the side wall of the power supply box; the inductor is electrically connected with the circuit board; and the inductor is formed by winding a fine wire with a diameter less than 0.01mm. According to the utility model, the fine wire with the diameter less than 0.1mm is adopted and insulating heat-conductive elastic cushions are loaded at two ends of a coil and are fixed by using fixing pressing plates with annular flanges, so that an effective area is increased, the volume of the inductor is reduced and the volume is reduced to 1/5 of the original volume.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to a kind of inductive type LED power supply.
Background technology
When we design the LED power supply, be necessary to know LED electric current, voltage characteristic, because the manufacturer of LED and LED specification are different, electric current, voltage characteristic are all variant.Existing is example with the white light LEDs ideal format, and according to electric current, the change in voltage rule of LED, generally using forward voltage is about 3.0-3.6V; Representative value voltage is 3.3V, and electric current is 20mA, after the forward voltage that is added on the LED two ends surpasses 3.6V; The increase that forward voltage is very little, the forward current of LED all might rise at double, makes the temperature rise of LED illuminator too fast; Thereby quicken the LED optical attenuation, make the lost of life of LED, when serious even burn out LED.According to voltage, the electric current variation characteristic of LED, the design proposition of power supply is strict with.
Inductance in the existing LED 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.
Summary of the invention
The present invention provides a kind of inductive type LED power supply, and the inductance caloric value that has mainly solved existing LED power supply is big, bulky technical problem.
Concrete technical solution of the present invention is following:
A kind of inductive type LED power supply; Comprise wiring board, power supply box body and power supply lid, above-mentioned wiring board is fixedly set in the power supply box body, and above-mentioned 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; Above-mentioned power pack body sidewall is provided with inductance, and inductance is electrically connected with wiring board; Above-mentioned inductance is through the fine rule coiling of diameter less than 0.01mm.
Above-mentioned inductance is fixed on the power pack body sidewall through screw; Be provided with the insulating radiation elastomeric pad between above-mentioned inductance one side and the power pack body sidewall; Above-mentioned 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.
The invention has the advantages that:
The present invention has adopted the fine rule of diameter less than 0.1mm; Adopt 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 has been fixed again, increased effective area; Dwindle the volume of inductance, can volume have been reduced to original 1/5.
