In addition, positive temperature characterisitic resistive element PTC 1 and negative temperature characteristic resistive element NTC 1, NTC 2 etc. are wound on the solderless wrapped connection pin 67 of substrate 64, and connect configuration near luminous tube 14.

Below, the action of this ignition device 17 is described.

At first, behind power connection, utilize the voltage of 71 couples of commercial ac power source e of full-wave rectifier to carry out full-wave rectification, and make its cunning that flattens with electrolytic capacitor C2 by level and smooth.

Apply voltage by resistance R 1 to the grid of N slot field-effect transistor Q1, field-effect transistor Q1 conducting.Follow the conducting of field-effect transistor Q1, the closed circuit voltage that is applied in of a winding L 2, capacitor C3, resonant capacitor C4 and the capacitor C5 of transformer CT, the winding L 2 of transformer CT, capacitor C3, resonant capacitor C4 and capacitor C5 resonance.At this moment, the impedance composition of positive temperature characterisitic resistive element PTC 1 also is contained in the part of resonance synthetic ingredient.And, at the harmonic wave corresponding voltage of the Secondary Winding L3 of transformer CT induction generation with the inductance composition of the winding L 2 of transformer CT, the LC series circuit natural resonance of the capacitor C7 of grid control circuit 76 and inductor L4, and produce the voltage that the frequency with almost fixed makes field-effect transistor Q1 conducting, field-effect transistor Q2 is ended.

Then, the resonance potential of a winding L 2, capacitor C3, resonant capacitor C4 and the capacitor C5 of transformer CT is reverse, Secondary Winding L3 produces and last time opposite voltage, and grid control circuit 76 produces the voltage that makes field-effect transistor Q1 end, make field-effect transistor Q2 conducting.In addition, the resonance potential of a winding L 2, capacitor C3, resonant capacitor C4 and the capacitor C5 of transformer CT oppositely after, field-effect transistor Q1 conducting, field-effect transistor Q2 ends simultaneously.Also identical later on, field-effect transistor Q1 and alternately conducting of field-effect transistor Q2, end, produce resonance potential, and flow through resonance current.

Flowing through under the state of this resonance current, because the temperature of positive temperature characterisitic resistive element PTC 1 is lower, resistance value for example is low to moderate 3k Ω～5k Ω approximately, and the electric current that flows to positive temperature characterisitic resistive element PTC 1 is bigger.The resonance potential that results from this moment between the two ends of resonant capacitor C4 reduces.

Follow the positive temperature characterisitic resistive element of current direction PTC 1 to produce Joule heat, when the electric current that rises, flows to positive temperature characterisitic resistive element PTC1 when the resistance value of positive temperature characterisitic resistive element PTC 1 reduces, the resonance synthetic ingredient changes, so the resonance action also changes, the electric current that flows to resonant capacitor C4 is increased, go forward side by side and exercise the soft start action that resonance potential raises gradually.

In addition, the part of resonance current is also passed through the capacitor C5 of electrode filaments coil FLa, the FLb flow direction of fluorescent lamp FL as the part of resonant capacitor, so the sufficient time of electrode filaments coil FLa, FLb cost is directly warmed-up, and rises up to resonance potential.And, by resonance electricity consumption container C 5 being set independently with resonant capacitor C4, can cut apart the resonance desired volume, the electric current that flows through when making the capacity of capacitor C5 that the preheating of electrode filaments coil FLa, FLb and fluorescent lamp FL are lit a lamp becomes suitable value, preheating electrode heater winding FLa, FLb efficiently, and can reduce to flow to after fluorescent lamp FL lights a lamp the electric current of capacitor C5, so the efficient after also can preventing to light a lamp reduces.

In addition, resistance value increase as positive temperature characterisitic resistive element PTC 1, because the variation resonance current of resonance composition increases, and the winding L of transformer CT that constitutes ballast choke is 2 saturated, when voltage rises to lamp and starts needed voltage, fluorescent lamp FL begins discharge and starting, lights a lamp.

After fluorescent lamp FL lit a lamp, the resistance value of positive temperature characterisitic resistive element PTC 1 was about tens k Ω, and the resistance value that the equivalent resistance of fluorescent lamp FL is compared positive temperature characterisitic resistive element PTC 1 is enough little, so resonance potential reduces, fluorescent lamp FL keeps lighting a lamp.Like this, by positive temperature characterisitic resistive element PTC 1 and resonant capacitor C4 are connected in parallel, rather than be connected in parallel, can reduce to flow to the electric current of electrode filaments coil FLa, FLb, correspondingly can suppress power consumption with capacitor C5.

Like this, can be according to the variation of the resistance value of positive temperature characterisitic resistive element PTC 1, suitably carry out the electrode filaments coil FLa of fluorescent lamp FL, the preheating of FLb, undesirable dispersing (splashing) occur, the point that can the improve fluorescent lamp FL life-span number of times that goes out so can prevent emitter stage.

And, under the lower state of the temperature of negative temperature characteristic resistive element NTC 1, NTC 2 before the fluorescent lamp FL starting, the resistance value of negative temperature characteristic resistive element NTC 1, NTC 2 is bigger, so the part of resonance current flows to electrode filaments coil FLa, the FLb of fluorescent lamp FL, suitably with electrode filaments coil FLa, FLb preheating.In addition, along with resonance current becomes big, owing to also flow to the part of the resonance current of negative temperature characteristic resistive element NTC 1, NTC 2 a little, negative temperature characteristic resistive element NTC 1, NTC 2 are owing to Joule heat generates heat, also be subjected in addition making temperature rise from the heat affecting of fluorescent lamp FL, the resistance value of negative temperature characteristic resistive element NTC 1, NTC2 reduces.Thus, the electric current that flows to electrode filaments coil FLa, FLb flows to negative temperature characteristic resistive element NTC 1, NTC 2 gradually.

In addition, after fluorescent lamp FL lights a lamp, the temperature of negative temperature characteristic resistive element NTC 1, NTC 2 raises and resistance value when infinitely reducing, the major part of resonance current flows to negative temperature characteristic resistive element NTC 1, NTC 2, and flow to electrode filaments coil FLa, FLb hardly, so can ad infinitum reduce the power consumption of electrode filaments coil FLa, FLb.

And, on substrate 64, from lamp holder 12 sides promptly one distolateral be that another is distolateral to luminous tube 14 sides, be formed with in regular turn the input power circuit E that is connected with lamp holder 12, with the efferent of the inverter circuit 72 of importing inverter circuit 72 that power circuit E is connected, being connected with luminous tube 14.Thus, the wiring figure that is formed on the substrate 64 is set facing one direction in an orderly manner from the input side to the outlet side, can make substrate 64 miniaturizations.

Then, when assemble compact self-ballasted fluorescent lamp 11, a distolateral and support 15 of illuminated in combination pipe 14 injects bonding agent 57 from the inboard of support 15 by each hole portion 46 and each inserting hole 52, a distolateral and support 15 of the luminous tube 14 that is adhesively fixed.Then, the both side edges portion of substrate 64 is inserted in a pair of substrate mounting groove 54 of support 15, the inboard that substrate 64 is inserted supports 15 is with each seal wire 37 that is drawn out to the luminous tube 14 of support 15 inboards reel (omitting the diagram of this reeling condition) on each solderless wrapped connection pin 67 that is connected substrate 64.Then, combination and splice holder 15 and cover body 13.Then, the not shown electric wire that will connect in advance from the input part side of substrate 64 is connected with eyelet 23 with the housing 21 of lamp holder 12, is entrenched in lamp holder 12 on the cover body 13 and by riveted joint or be adhesively fixed.Then, make lamp holder 12 towards downside, make luminous tube 14 towards above state under, notch part 56 by support 15 is to the inboard filling heat-conductive material of lamp holder 12, thereby at least and electronic unit 66 such as the transformer CT that exists in opposite directions of notch part 56 sides of support 15 and lamp holder 12 and cover body 13 sides between fill thermally conductive materials, perhaps to the whole inboard thermally conductive materials of filling of lamp holder 12.Then, glass bulb 16 is covered on the luminous tube 14, utilize bonding agent that glass bulb 16 is fixed on the cover body 13.

When a distolateral and support 15 of the luminous tube 14 that is adhesively fixed, as described above, the front of not shown anchor clamps that will be used to inject for example needle-like of bonding agent 57 is inserted clearance portion 48 from the inboard of support 15, makes from the front of anchor clamps and flows out bonding agent 57.The bonding agent 57 that flows out to clearance portion 48 is filled in the clearance portion 48, and logical via portion 46 flows out to the outside of jut 44, advances along the periphery inside part of vacuum tube end 31a, 32a, 33a and the gap between the depressed part 45 and injects this gap.At this moment, logical via portion 46 flows out to the bonding agent 57 in the outside of jut 44, advance along the periphery inside part of vacuum tube end 31a, 32a, 33a and the gap between the depressed part 45, advance by utilizing based on the resistance inhibition bonding agent 57 in this gap, can make bonding agent 57 be difficult for spilling into the outside, prevent to be blocked by the bonding agent that is overflowed 57 from the light that the periphery Outboard Sections of vacuum tube end 31a, 32a, 33a sends from the periphery inside part of vacuum tube end 31a, 32a, 33a and the gap between the depressed part 45.

In addition, one side flows out bonding agent 57 one sides makes anchor clamps round along clearance portion 48, between the periphery inside part of all vacuum tube end 31a, 32a, 33a and each depressed part 45, similarly inject bonding agent 57 thus, the periphery inside part of vacuum tube end 31a, 32a, 33a is adhesively fixed on the depressed part 45 and wall portion 47 of jut 44 of support 15.Like this, only flow out bonding agent 57 one sides anchor clamps are rounded along the circumference face of jut 44 and the clearance portion 48 between the wall portion 47, can carry out bonding agent at a dass and inject operation, can improve operating efficiency by one side.

And as shown in figure 10, for example the lighting device 81 as high courtyard lamp has ligthing paraphernalia main body 82, and lamp socket 83 and reflector 84 are installed in this ligthing paraphernalia main body 82, and compact self-ballasted fluorescent lamp 11 is installed on lamp socket 83.

In this compact self-ballasted fluorescent lamp 11, the substrate 64 of the width dimensions that can insert lamp holder 12 inboards will be formed, centerline direction along lamp holder 12 vertically disposes, and be configured in the position of the disalignment of relative lamp holder 12, thus can be at the large-scale electronic unit 66 in the one side configuration electronic unit 66 of substrate 64 and interval broad lamp holder 12, so ignition device 17 can be accommodated in efficiently the inboard of lamp holder 12, can make cover body 13 miniaturizations thus.

Make near lamp holder 12 and to be positioned at the electronic unit 66 of the edge portion side on the width of substrate 64 oblique towards the width central portion inclination of substrate 64, so this electronic unit 66 can be accommodated in ignition device 17 inboard of lamp holder 12 efficiently not to be inserted into lamp holder 12 inboard state of contact.

About being installed in the level and smooth electrolytic capacitor C2 that uses highly higher in the electronic unit 66 on the substrate 64, can install towards relative substrate 64 vertical directions at the width middle section of the one side of substrate 64, so the installation effectiveness of substrate 64 improves, and can make substrate 64 miniaturizations.

From lamp holder 12 sides be substrate 64 one distolateral be that another of substrate 64 is distolateral to luminous tube 14 sides, form the efferent of input power circuit E, inverter circuit 72, inverter circuit 72 in regular turn, the wiring figure that is formed at substrate 64 is set from the input side to the outlet side facing one direction in an orderly manner, can make substrate 64 miniaturizations.

And, by along the direction of the center line of lamp holder 12 vertically configuration form the substrate 64 of the width dimensions that can insert lamp holder 12 inboards, the leading section of can be between the inboard of lamp holder 12 and substrate 64 having been enclosed main mercury alloy 39 in the tubule 38 of configuration luminous tube 14, reduce the heat affecting of the 14 pairs of main mercury alloys 39 of luminous tube when lighting a lamp, ignition device 17 and tubule 38 can be configured in efficiently the inboard of lamp holder 12, can make cover body 13 miniaturizations thus.

Substrate 64 is configured in the position of the disalignment of relative lamp holder 12, tubule 38 is configured between the narrower one side side in interval substrate 64 and lamp holder 12, so can be at the large-scale electronic unit 66 of one side side configuration of substrate 64 and interval broad lamp holder 12, ignition device 17 and tubule 38 can be configured in efficiently the inboard of lamp holder 12.

To the inboard filling heat-conductive material of lamp holder 12, utilize this thermally conductive materials to make electronic unit 66 and the lamp holder 12 side thermally coupleds of bigger transformer CT of caloric value etc. at least, so can make the heat efficiently radiates heat of electronic unit 66.

And, the compact self-ballasted fluorescent lamp 11 of Gou Chenging as shown in Figure 1 like this, make that to have external diameter of pipe be 3～8mm, be preferably the vacuum tube 31 of 6～7mm, 32, the Breadth Maximum b1 of the width of 33 luminous tube 14 is below 30mm, for example form 20～30mm, the size h2 that can make the cover body 13 that exposes from lamp holder 12 ratio of the lamp length dimension h1 except that lamp holder 12 relatively forms 0～25%, make the maximum outside diameter b2 of cover body 13 form 1.0～1.5 times of outside dimension b3 of lamp holder 12, or 0.48～0.73 times of the maximum outside diameter b4 of glass bulb 16, the outside dimension (identical with b2) of lamp holder 12 sides of glass bulb 16 is formed below 40mm, for example form 30～35mm.Thus, can obtain with general lighting such as incandescent lamp with the roughly the same outward appearance of bulb.For example in the present embodiment, the overall height dimension that comprises lamp holder 12 is 105～115mm, and is measure-alike with 60W type incandescent lamp.In addition, when the external diameter of pipe of vacuum tube 31,32,33 during less than 3mm, starting voltage rises and luminous efficiency reduces, and the making of vacuum tube 31,32,33 also becomes difficulty, and greater than 8mm the time, is difficult to reduce the maximum outside diameter of cover body 13.And the Breadth Maximum of luminous tube 14 is difficult to reduce the maximum outside diameter of cover body 13 during greater than 30mm.Lamp length dimension h1 except that lamp holder 12 is 80～90mm, the size h2 of the said cover body 13 that exposes from lamp holder 12 ratio of this size h1 relatively is 0% to be meant when width is observed compact self-ballasted fluorescent lamp 11, the state that cover body 13 does not expose from lamp holder 12 fully, when this situation, the edge portion 61 of the peristome 60 of glass bulb 16 is entrenched on the housing 21 of lamp holder 12, and greater than 25% o'clock, be difficult for obtaining near outward appearance and the light distribution characteristic of general lighting with bulb.In the present embodiment, h2 is 6～11mm, and the best is about 8mm, with maintenance and the mechanical strength of guaranteeing glass bulb 16.And, as the maximum outside diameter b2 of cover body 13 during less than 0.48 times of the maximum outside diameter b4 of 1.0 times of the outside dimension b3 of lamp holder 12 or glass bulb 16, one distolateral supporting and taking in of ignition device 17 of luminous tube 14 becomes difficulty, and greater than 0.73 times of the maximum outside diameter of 1.5 times of the outside dimension of lamp holder 12 or glass bulb 16 time, be difficult for obtaining near outward appearance and the light distribution characteristic of general lighting with bulb.In addition, the maximum outside diameter b4 of glass bulb 16 is 50～60mm, and the best is about 55mm, and the external diameter b3 of lamp holder 12 is 26～28mm.
