Description

Light regulator

The utility model relates to a kind of dimmer that is contained in the floor lamp bar.

General powerful indoor lamp is all considered to adopt dimmer usually, so that can regulate luminosity on demand, and the while conservation of power.The initial dimmer that occurs is the sincere type of pin, is box-like, is placed on the ground.The power line of being come by socket must feed this box earlier, again by coming out to enter floor lamp in the box.The dimmer shortcoming of this form is a lot: at first be operation inconvenience, because this dimmer itself is very light, as be placed on the ground of smoother when removing to promote toggle (slidingtype rheostat button) on the dimmer with pin, often connecting dimmer slides on the floor together, let alone to the fine adjustments of luminosity, and box is placed on the ground, unavoidably will be trampleed on, so the regulation pin is sincere in the security for all countries standard will stand the test that 100 pound weight things were pressed 1 minute.Because of it is to be placed on the ground, stumbling easily again, so the 35 pound weight power that stand are again drawn one minute tensile test, so infrastructure cost is very high.If box has turned over body, finally still the very important person stoop that waist goes it is turned over could mobile toggle.In fact want carefully to regulate and control luminosity, for the sincere formula dimmer of this pin, can only stoop waist and catch the box body with a hand, the another hand is stirred toggle.Next is length and the floor space that has increased power line.The 3rd is to have increased the chance that the high frequency width of cloth is penetrated, because dimmer is the centre that is in power line two ends (plug and base), so these two sections power lines all might become the transmitting antenna of radio interference ripple, disturbing wave that dimmer produced to around emission ....

Therefore, there is the people dimmer to be contained in the lamp stand of floor lamp at present, but up to now, this trial also belongs to just and begins, just merely be placed in the lamp stand the sincere dimmer of pin, the rotating potentiometer of original slidingtype rheostat with a belt switch replaced, and this potentiometer is fixed on the lamp stand by nut with common mode.This floor lamp is existing sale the on market at present, use be earth-free twin-core power line, three-section type combination lamp stand is with being threaded.This structure (referring to Fig. 1, Fig. 2 and simple introduction hereinafter) can't be accepted by the safety standard of the world at all.

Main purpose of the present utility model provides a kind of lamp stand formula dimmer that meets in the world machinery and electric product safety requirements; Another purpose of the utility model is that a kind of lamp stand formula dimmer that can eliminate the incongruous profile in the prior art in shape-designing is provided; Another purpose of the utility model is that this lamp stand formula dimmer itself can also play the effect of the plug-in type jockey of segment type lamp stand, makes this kind connection more firm.

The purpose of this utility model is to reach by following mode: lamp stand formula dimmer of the present utility model comprises the controllable silicon that is contained on the printed substrate, the bilateral diode, switch, potentiometer, capacitor, it is characterized by, has a dimmer shell, this dimmer shell is to be smoked to close by two hollow semi-cylindrical shells (being called for short half housing later on) that plastic cement is made to be fastened as, be shaped on above this double housing any one with lamp stand on the boss that matches of the hole left, after band boss half housing that is loaded with the wiring board of electronic component put into lamp stand making this boss cooperate this hole, second half housing can resemble drawer-like ground and insert back-off on two and half housings and fasten and form the complete shell that is fixed in the position, and be fixed in the lamp stand, this meets the properly fixing and requirement that can not be opened mechanically fully.

Also having increased the formula of the falling L trapper of being made up of capacitor and high-frequency inductor coil is in the circuit board spread out of to supply network by power line to stop the interference electric wave more than 10 KHz.Any end of this dimmer shell can be made into the positioning and fixing part of plug-type connector arrangement.On the boss plane of this dimmer shell, can assemble switch, become resistance toggle, indicator light and so on part with the control panel that forms and the lamp stand contour curve is coordinated.Make whole dimmer be in the coat of metal among the metallic shield fully electroplating one deck on part or all outer surface of described plastic shell, the coat of metal that is plated on plastic shell is contacted with the inner surface of metalized lamp rod, the metalized lamp rod of adjacent two joints of conducting, thus use three core power lines or two core ground connection type power lines to make lamp stand and other metallic shield ground connection.

In order to describe concrete structure of the present utility model in detail, please refer to accompanying drawing, wherein:

Fig. 1 is that the structure of the lamp stand formula dimmer of prior art is installed cutaway view;

Fig. 2 is the electric circuit diagram of the lamp stand formula dimmer of prior art;

Fig. 3 is that the structure of the utility model lamp stand formula dimmer is installed cutaway view;

Fig. 4 is the electric circuit diagram of the utility model lamp stand formula dimmer;

Fig. 5 is the plastic cement case front view of the utility model lamp stand formula dimmer;

Fig. 6 is the plastic cement case end view of the utility model lamp stand formula dimmer;

Fig. 7 is two profiles of the shell boss of the utility model lamp stand formula dimmer when adopting large tracts of land.

Please see Fig. 1 earlier, here represented a side sectional view of the lamp stand formula dimmer of prior art, wherein 1 is lamp stand, common iron pipe with inch about half, at circular hole of tube wall upper punch, so that the threaded portion of variable resistor (generally using carbon membrane formula variable potentiometer) can stretch out.Part 2 is circuit boards, and part 3 is capacitor C, and part 4 is controllable silicon T, and part 5 is diode D, and part 6 is potentiometer VR of belt switch SW, and part 7 is nuts that the fixed potential device is used.Be the electrical schematic diagram of Fig. 1 shown in figure 2.L among Fig. 2 is load, here is incandescent lamp bulb, and U represents voltage.As can be seen from Fig. 1, as long as nut 7 is released, whole dimmer is just movable in iron pipe 1.Even nut 7 does not get loose, because whole dimmer is a frictionally to fix motionlessly, this is can not be received.Because the activity of knob is two-way, so nut 7 in theory just cannot keep not easing out.From Fig. 1, also can see, there is no insulated envelope between all live components and the iron pipe 1, if any element sealing-off, its pin just may directly contact the inwall of iron pipe 1, in addition the rust dirt of inwall can be scattered in and causes fault on the circuit board, and this also is can not be received.Can see that from Fig. 2 the interference electric wave that controllable silicon T sends can pass to supply network along power line, the broadcast receiver that causes being connected in the same socket sends the grunt that ear can be heard, this is again can not be received.

Have again, because Fig. 1, prior art floor lamp under Fig. 2 has used an earth-free twin-core power line, under described in the above structure and the circuit conditions, between the palp metal part of any one hand of power line electric conductor and lamp is divided, to and not punch with 4,000 volts of alternating currents energising one minute, and whole small cup lamp is placed on to keep in the moist drying room taking out after 24 hours switched on one minute with 1500 volts of alternating currents immediately and do not punch.The lamp of prior art will be subjected to incessantly high voltage test in the dimmer part in these cases, after especially making moist, and the staining of dirt because whole dimmer circuit plate is become rusty, leakage current can be accepted greatly and not very much.

See Fig. 3 now, it is that the structure of the utility model lamp stand formula dimmer is installed cutaway view, the obvious difference of Fig. 1 of it and prior art has been many one by the synthetic plastic cement case 8 of two hollow semicylinders.The profile that in Fig. 5, has shown plastic cement case 8.Can see in Fig. 5 on one and half shells in the place ahead has an oblong boss, and it is used for being embedded in from inside to outside in the respective aperture on the lamp stand, sees Fig. 6.Fig. 6 is that two hollow semicylinders of this shell 8(lump together) end view.Because the external diameter of shell 8 just equals to manage 1 internal diameter, so when 8 first half being put into pipe 1, and after making boss on 8 embed in the respective aperture of pipe 1,8 latter half is filled in the pipe 1 again, and after withstanding button dead (with hasp commonly used in the plastic cement products industry), whole casing 8 just forms one, outward appearance be can't see fixed screw, both convenient for assembly, attractive in appearance again complete, and can not take out again.Though the shape of boss and size are without limits, but when boss adopts than large tracts of land, the plane of boss is significantly in the periphery profile of the original iron pipe of retraction, if use the slidingtype rheostat this moment, its toggle just can not resemble the periphery profile that protrudes from iron pipe the knob of prior art widely, surmount prior art in appearance greatly, see Fig. 7, this structure extremely is fit to switch rheostat (replacement potentiometer) and the similar slidingtype rheostat in our patent application formerly 93232726.5 of employing, in addition, when the boss area is big, being become by the simple control forms of having only a switch originally to have a switch, a control panel form that becomes resistance (light modulation) button and a plurality of controlled objects compositions of an indicator light (light-emitting diode) has increased commercial competition.Shortcoming and rheostat as for the potentiometer belt switch see also above-mentioned patent application formerly 93232726.5 with the advantage that switch separates

Have only and adopted shell 8 of the present utility model, could be included in all live components for a full due in insulation (plastic cement) case at one stroke, just can make whole small cup lamp use the twin-core power line qualifiedly, solved the firm installation question of dimmer simultaneously.Therefore used shell 8, product can export to the state of radio interference no requirement (NR) has been returned home.

In order to make product can export to All Countries, lamp stand formula dimmer of the present utility model is except the trap circuit that has added the formula of falling L as shown in Figure 4 is sent to supply network to stop the interference electric wave more than 10 KHz by power line, also utilized pipe 1 and (or) shell 8 as metallic shield prevent to disturb electric wave to external radiation.Promptly by the outer surface plating that exposes the boss (perhaps whole casing 8) of the shell 8 of iron pipe 1 being made whole dimmer all be among the metallic shield.Certainly, metallic shield is all with traditional method ground connection, and this product can stride across shell with a plain conductor and will need earth terminal to fuse and don't influence outward appearance, because of the shell skin still have an iron pipe overlapping so, in each figure, no longer illustrate.Because the two ends of iron pipe 1, an end is the base of metal, and an end is the lampshade of metal, so the intermediate frequency transformer case of practical function in broadcast receiver plays the shielding protection of mechanicalness and electric property simultaneously.

After above-mentioned increase trap circuit and comprehensive metallic shield, the broadcast receiver that is inserted in the same supply socket be can't hear the interchange grunt fully.And the prior art of usefulness as a comparison, promptly at present on market the existing floor lamp of selling very significantly AC hum is but arranged.

Pipe 1 among Fig. 3 with the pipe 1 ' be connected, be that (application number: the structure in plug-in type lamp stand jockey PCT/CN94/00028) connects for international application formerly according to the inventor, because part 8 and pipe 1 can firmly link to each other, so no longer needed the interior scrobicular ring muscle of image tube 1 ' make like that in the end of managing 1.The connection mechanism on part 11 and part 8 tops sees also the plug-in type lamp stand jockey of International Application PCT/CN94/00028 formerly of the inventor, the benefit of doing like this is that the needed positioning and fixing part of original connector has just been served as by part 8, plastics have promptly been saved with interior scrobicular ring muscle production process, again because the length of part 8 and fixedly fastness all substantially exceed the positioning and fixing part of original connector, thereby improved the fastness that connects.

Contrast Fig. 3 and Fig. 1, (wherein identical part with identical numbering) difference be to have increased positioning and fixing by plug-in type bindiny mechanism partly changes expansion and be not to lump together during the actual use of plastic shell 8(that forms with the plug-in type coupling mechanism), and the part of trap circuit----part 13 is capacitor C 1, part 10 is high-frequency inductor coil HFC, and part 9 is resistance R, part 6 in Fig. 3 ' be switch, here the potentiometer branch of it and part 6 has been come, avoided the inhomogeneous of the rheostatic common fault of belt switch----carbon film and wearing and tearing too early.Part 12 is the fuses that increase newly, because the fuse 12 on the figure cannot be changed after once assembling excessively, so preferably adopt nonexpondable kind, Fig. 3 is the example that is used for 300 watts of quartz lamps, turn picture around, in fact power line (not drawing among the figure) is entered behind the iron pipe on the road direction by ground, enter pipe 1 ' after enter shell 8 again, pressing plate that also has common securing electric lines in shell 8 and so on installs (not shown) electric wire is fixed, then by the switch line attachment.Outlet also has the anti-principal vertical line of pressing plate of securing electric lines and so on device (also not showing among the figure) to be drawn out, and outlet (not drawing among the figure) enters lampshade (not drawing among the figure) after going out pipe 1.

As seen from Figure 3, words as the left side of shell 8 half (expose iron pipe 1 half) outer surface plated metal, whole dimmer has been wrapped in the metal screen cover, its shielding situation just as the intermediate frequency transformer cover in the common broadcast receiver (promptly except several line outlets, outside the tuning screw mouth, shielding has been lived fully).And because pipe 1 and pipe 1 ' inner surface be the iron of not painting, so plate surface is two iron pipe conductings.Make the earth connection G of the triple core wire among Fig. 4 as long as base (metallic) just can be finished in a ground connection termination the----ground connection of the whole metal architectures of lamp stand (iron pipe)----lampshade (metallic).

Space in the shell 8 is very big as can be seen in Fig. 3, and this is can increase some other elements, for example fin and so on for the occasion at high-power (greater than 500 watts).

In addition, the a pair of pin key shape thing 14 that root is divided in the Plug Division that protrudes from is arranged at apparent shell 8 tops in Fig. 5, Fig. 6, prevent to manage 1 with pipe 1 ' relative rotation usefulness takes place to connect the back, its explanation sees International Application PCT formerly/CN94/00028(plug-in type lamp stand jockey of the inventor for details).This establishes in order to meet the twisting that can not make electric wire surpass 360 ° in the security for all countries standard, if prevented above-mentioned relative rotation with additive method in any design, then this a pair of pin key can be cancelled fully.

If Fig. 4 is used in 230 volts of Europe, 50 hertz of power supplys are when load is 300 watts of incandescent filaments, the parameter of major part is: C1=0.1 microfarad, VR=500 kilo-ohm, R=10 kilo-ohm, the C=0.082 microfarad, the HFC=2 milihenry, controllable silicon needs only current/voltage enough greatly, for example 10 peaces, 400 volts, bidirectional diode is with 5 volts, 100 microamperes, 12.5 hertz of theoretical trap frequencies and more than.
