[embodiment]

In LED illuminating lamp shown in Figure 1, Switching Power Supply Unit 200 and LED illuminator Unit 300 are chief components of LED illuminating lamp.

Because the operating voltage of LED light emitting diode is very low, generally have only about 3 volts, so Switching Power Supply must adopt transformer output.In addition,, require the volume of Switching Power Supply also very little, and the LED illuminating lamp here adopt full-enclosed structure, the non-constant of radiating condition because the volume of LED illuminating lamp is very little; In order to reduce the volume of switching mode power supply transformer, generally all switching frequency is obtained than higher, but switching frequency is got after the height, operating efficiency can reduce, and be easy to cause high frequency electromagnetic radiation to disturb and Conduction Interference, because this Switching Power Supply can't ground connection, also can't carry out electromagnetic shielding, therefore must consider the EMC electromagnetic compatibility technology problem of LED illuminating lamp.

For this reason, will adopt the Switching Power Supply of different circuit structures here at the LED illuminating lamp of different capacity,, intend adopting single excitation type switch power-supply for low-power LED illuminating lamp (such as below 3 watts); For the bigger LED illuminating lamp of power (such as more than 3 watts) can adopt two excitation type switch power-supplies.

Because the change in magnetic flux density scope of the magnetization curve of single excitation type switch power-supply transformer core is littler a lot of times than the change in magnetic flux density scope of the magnetization curve of two excitation type switch power-supply transformer cores, therefore under same power, the volume of single excitation type switch power-supply transformer is more a lot of greatly than the volume of two excitation type switch power-supply transformers; But the circuit of single excitation type switch power-supply is relatively simple, and therefore single excitation type switch power-supply is only applicable to the less occasion of power output.

Fig. 2 is the magnetization curve schematic diagram between magnetic flux density (magnetic induction intensity) and the magnetic field intensity in single excitation type switch power-supply transformer core.In Fig. 2, H is a magnetic field intensity, and Hm is a maximum magnetic field strength, and Hs is the magnetic saturation magnetic field intensity; B is a magnetic flux density, and Br is a residual magnetic flux density, and Bm is a peakflux density, Δ B incremental magnetic flux density (being the change in magnetic flux density scope), and Bs is the magnetic saturation magnetic flux density; Curve 0-s is that initial magnetization curve (is that transformer core is when being magnetized for the first time, the relation curve of the corresponding variation of magnetic flux density) with magnetic field intensity, when curve 1 and curve 2 are the work of single excitation type switch power-supply respectively, the magnetization curve that transformer core is magnetized and demagnetizes.

Curve 1 expression, when the exciting current that flows through transformer increases, will magnetize to transformer core in the magnetic field of its generation; When magnetic field intensity H reaches maximum Hm, corresponding magnetic flux density B will be magnetized peakflux density Bm.Curve 2 expressions, when the exciting current that flows through transformer reduces, will demagnetize to transformer core in the magnetic field of its generation; When magnetic field intensity H dropped to 0 by maximum Hm, corresponding magnetic flux density B also got back to residual magnetic flux density Br by peakflux density Bm demagnetization.

Fig. 3 is the magnetization curve schematic diagram between magnetic flux density (magnetic induction intensity) and the magnetic field intensity in two excitation type switch power-supply transformer cores.In Fig. 3, H is a magnetic field intensity, and Hm is a maximum magnetic field strength, and-Hm is negative maximum magnetic field strength; B is a magnetic flux density, and Br is a residual magnetic flux density, and Bm is a peakflux density, and-Br is negative residual magnetic flux density, and-Bm is negative peakflux density, Δ B incremental magnetic flux density; Curve 0-a is that initial magnetization curve (is that transformer core is when being magnetized for the first time, the relation curve of the corresponding variation of magnetic flux density) with magnetic field intensity, when curve e-f-a-b-c-d-e is two excitation type switch power-supplies work, the magnetization curve of transformer core (also being hysteresis curve).Electric current in the switching mode power supply transformer primary coil is by just to negative, again by just bearing, every variation one-period, magnetic field intensity H in the transformer core and the pairing magnetization curve of magnetic flux density B will change once back and forth along hysteresis curve e-f-a-b-c-d-e.

Fig. 4 is the fundamental diagram of single excitation type switch power-supply.Among Fig. 4, Unit 201 are the rectifying and wave-filtering input circuit, also comprise EMC or EMI filter circuit simultaneously, and Unit 202 are switching mode power supply transformer, and C1 is the energy storage filter condenser; Unit 203 are on-off circuit, wherein also comprise integrated circuit controller and switching device, and switching device comprise transistor or FET etc.; Unit 205 are the rectifying and wave-filtering output circuit, and the LED light emitting diode that its output voltage is fed in Unit 300 is powered, and Dn is a light emitting diode, i.e. LED core or surface mount light emitting diode.

During operate as normal, Unit 203 can ceaselessly allow the switch device work in conducting and end two states, make input voltage will be added to the two ends of switching mode power supply transformer 202 intermittently,, induced voltage output is just arranged in the secondary coil of switching mode power supply transformer 202 by electromagnetic induction.The correct dutycycle of Unit 203 and the turn ratio of operating frequency and switching mode power supply transformer 202 primary and secondary coils selected just can make switching mode power supply transformer 202 secondary coil output voltages satisfy the requirement of LED light emitting diode in Unit 300.

Here point out in passing that most of single excitation type switch power-supplies are all selected inverse-excitation type for use, because in inverse-excitation type switch power-supply, require the withstand voltage parameter of switching device to hang down than positive activation type Switching Power Supply; But, also can select the positive activation type Switching Power Supply for use in the lower occasion of input voltage.The difference of positive activation type Switching Power Supply and inverse-excitation type switch power-supply mainly is that the phase place of the primary and secondary coil of selector switch power transformer is respectively different mutually.

When 203 switching device conductings, if the secondary coil of switching mode power supply transformer provides power output to load, then this Switching Power Supply is referred to as the positive activation type Switching Power Supply; Otherwise, when 203 switching device conductings, the secondary coil of switching mode power supply transformer does not provide power output to load, but when 203 switching devices end, the secondary coil of switching mode power supply transformer just provides power output to load, and this Switching Power Supply is referred to as inverse-excitation type switch power-supply.Single excitation type switch power-supply only in 203 switching device conductings (normal shock) or when (anti-swash), just has voltage to export; Therefore, the output of single excitation type switch power-supply transformer secondary output coil generally all is to adopt halfwave rectifier output.

Fig. 5 is the fundamental diagram of two excitation type switch power-supplies.The kind of two excitation type switch power-supplies is a lot, and what select for use here is the two exciting switching voltage regulator circuit of semibridge system.Because the circuit of the two exciting switching voltage regulators of semibridge system is fairly simple, and requires the withstand voltage not really high of switching device.

Among Fig. 5, Unit 201 are the rectifying and wave-filtering input circuit, also comprise EMC or EMI filter circuit simultaneously, Unit 202 are switching mode power supply transformer, 203, Unit 204 are on-off circuit, and comprising integrated circuit controller and switching device, switching device comprises transistor or FET etc. again; 203,204 switching devices and energy storage filter capacitor C1, C2 form an electric bridge, and the primary coil of switching mode power supply transformer 202 is connected the centre of electric bridge; Unit 205 are the rectifying and wave-filtering output circuit, and its output voltage is fed to Unit 300 the LED light emitting diode is powered, and Dn is a light emitting diode, i.e. LED core or surface mount light emitting diode.

During operate as normal, energy storage filter capacitor C1 and C2 have been full of electricity basically, 203 and 204 switching devices are in turn conducting and ending respectively, energy storage filter capacitor C1 and C2 just can carry out charge and discharge in turn by the primary coil and 203 or 204 switching devices of switching mode power supply transformer 202, the electric current that flows through switching mode power supply transformer 202 primary coils is simultaneously also constantly carried out commutation, by electromagnetic induction, induced voltage output is just arranged in the secondary coil of switching mode power supply transformer 202.

Because energy storage filter capacitor C1, C2 in Fig. 5 circuit take turns conducting and between the off period at 203 and 204 switching devices, its both end voltage remains unchanged substantially, or variation is very little, and therefore, people call the semi-bridge switching voltage regulator circuit to this bridge switch power circuit of Fig. 5; In addition, owing to flow through the exciting current commutation back and forth of switching mode power supply transformer, so we call the two exciting switching voltage regulators of semibridge system to Fig. 5 circuit.

Two excitation type switch power-supplies, no matter in 203 and 204 switching device conductings with between the off period, the secondary coil of switching mode power supply transformer 202 all has voltage, electric current output, and therefore, the output of two excitation type switch power-supply transformer secondary output coils generally all connects bridge rectifier or full-wave rectifying circuit.

The Switching Power Supply that the LED illuminating lamp uses is easy to cause high-frequency electromagnetic to disturb, and particularly under the increasing situation of digital circuit equipment, the electromagnetic compatibility between the various device (EMC) problem must be considered.Generally, the operating frequency of Switching Power Supply is high more, and the degree that produces High-frequency Interference is just serious more; In addition, in the hard switching circuit, the operating efficiency of Switching Power Supply is high more, and the degree that produces High-frequency Interference is also serious more, because the intensity of the operating efficiency of Switching Power Supply and High-frequency Interference all just has very big relation with the turn-on and turn-off speed of switching device.For this reason, under the situation that volume of transformer allows, the operating frequency of Switching Power Supply obtain lower a little be good, perhaps adopt soft switch circuit, i.e. no-voltage or Zero Current Switch circuit, but that sort circuit is wanted comparatively speaking is complicated.

Fig. 6 is the cross section structure figure between each layer of LED illuminator, and Fig. 7 is the plane structure chart between each layer of LED illuminator.

In Fig. 6, Fig. 7, the LED illuminator structurally be broadly divided into following which floor;

301 is ground floor---substrate layer.Baseplate material can also can be used organic material with metal, and whether can it be convenient to depend primarily on production, and the requirement that satisfy mechanical strength.Because other each layer all is to make up to get up on the basis of substrate layer, and the LED illuminator mainly is connected and fixed by ground floor and bulb socket.

302 is the second layer---insulating barrier.The second layer must be selected the reasonable material of insulating property (properties) for use, if but ground floor also is to select the reasonable material of insulating property (properties) for use, the second layer and ground floor can be merged into one deck so.

303 is the 3rd layer---the conducting wire layer.The tube core of LED light emitting diode or surface mount LED light emitting diode just are mounted on the layer of conducting wire.Therefore, the 3rd layer of copper foil layer like PCB shop copper coin face, the manufacturing process of conducting wire layer and the manufacturing process of pcb board are basic identical; Generally all be line design good after, again by light paint, print, technology such as corrosion, finally only keep needed circuit to be close on the insulation material layer; But the conducting wire layer here also can adopt spraying or typography directly conductive material to be sprayed or is printed on the insulation material layer.In addition, also can adopt flushing technology, earlier Copper Foil be become the shape of required conductive strips with the machine punching out, and then conductive strips are pasted on the circuit board.

304 is the 4th layer---LED mounts layer, and promptly LED LED core or surface mount LED light emitting diode mount layer.Because the tube core volume of LED light emitting diode is very little,, be more hard-to-weld if adopt common welding; Therefore, the most handy silver slurry or other electrically-conducting paint directly stick on the tube core of LED light emitting diode on the conductive strips of wiring board; And surface mount LED light emitting diode generally can weld, but the cost of surface mount LED light emitting diode is high more a lot of than the cost of LED LED core.The tube core of light emitting diode or surface mount LED light emitting diode can also can be connected by column split, and then each group is carried out series and parallel by row grouping series connection, and last only the need is connected with 205 rectifying and wave-filtering output units with two leads.

305 is layer 5---reflector layer.Reflector layer is generally all very thin, and best reflectorized material can be that electroplating metal material is made on organic film but a lot of reflectorized materials are also arranged with tinsels such as tin-foil plate or aluminium foils.Do reflectorized material with reflective membrane or reflecting piece, can make a lot of wickets (square or circular) to reflective membrane or reflecting piece, the tube core of LED light emitting diode or surface mount LED light emitting diode just in time can be exposed from the wicket of reflector layer.In addition, for easy to process, reflector layer also can adopt spraying or typography, and reflectorized material is directly sprayed or is printed on the layer of conducting wire.

306 is layer 6---photic zone.Euphotic material can use transparent material, also can select for use the different composite material of multiple light transmitting property to be made, in euphotic inside or the surface can also make the light-scattering body that rearranges mutually by one or more geometric figures, allow light reflect mutually, so that improve the colour mixture effect or make the brightness of light softer evenly.

In Fig. 7, the tube core of LED light emitting diode or surface mount LED light emitting diode can be arranged by " product " font in Unit 304, also can arrange by " well " font; If the LED illuminating lamp adopts R, G, three kinds of color LEDs of B as light source, the light emitting diode of three kinds of colors is preferably arranged by the grouping of " product " font so, makes the colour mixture function just can reach optimum efficiency like this.

Some power ratios are bigger, and the LED illuminating lamp that the volume of LED illuminator is also bigger, structurally, can there be one to mate the part that links between bulb socket and the LED illuminator, one end of this part is fixedlyed connected with bulb socket, and the other end carries out separable the connection with the LED illuminator.In Fig. 1 and Fig. 7, mate the part that is connected between bulb socket and the LED illuminator and do not draw; Because the volume ratio of the LED illuminator of the LED illuminating lamp that Fig. 1 and Fig. 7 are represented is less, thisly can be directly than the compact LED illuminator carry out separable be connected or fixedly connected with bulb socket.
