Description

Extra low voltage lamp adaptor

Invention field

The present invention relates to be used for ultralow pressure (the Extra Low Voltage) lamp adaptor of lighting apparatus, relate in particular to the adapter that is suitable for vertical illumination or local lighting equipment, wherein it is modified as the GLS lamp of a replacement standard or the lighting apparatus of incandescent reflector lamp.Background technology

Lighting apparatus in family expenses and the commercial building is made of standard GLS lamp and the incandescent reflector lamp that the operating characteristic round them designs mostly now.The efficient of full confirmation ELV lamp is better than these light sources on market, and many new equipments are just using the ELV illuminator of rigid line connection.

Yet, for raising performance, the low running cost of safety and health the remodeling of existing GLS lamp and incandescent reflector lamp lighting apparatus is restricted to the electricity-saving lamp that uses the small fluorescent type up to now, perhaps in new more high efficiency light source, connect and revise existing lighting apparatus fully, perhaps or even the replacement of whole illuminator by rigid line.It is very high to be used for revising fully or replacing the expense that has illuminator now, and it also comprises sizable inconvenience and damage in the assembling process.Though the ELV illuminator can be saved a lot of running expenses and be had high efficiency, the scheme of revising or replacing existing standard GLS lamp and incandescent reflector lamp lighting apparatus fully often is considered to infeasible economically.Up to now, being used as unique non-rigid line that gets to the remodeling of existing illuminator, to connect the replacement system be compact fluorescent lamp.

The structure of compact fluorescent lamp normally has one or two structure (interchangeable pipe), and it is designed to supply of electric power converted to and makes fluorescence (small-sized) plumber make required different frequency or voltage or the like.This work generally includes electronic component and or the utilization of ferrite ballast.It is said that this lamp energy operation saving volume reaches 80%, but have several intrinsic design limitations.

The first, the design limitations of compact fluorescent lamp is its actual size.The obtainable change in size of many compact fluorescent lamps can not be designed to use the existing lighting apparatus of GLS lamp or incandescent reflector lamp to match.

Second, because lighting apparatus may need the switching cycle of short-term, luminous or not frequent or switching at once, they exceed the limit of power of control device of lamp or unhelpful to the life-span of fluorescent tube, are unfavorable so compact fluorescent lamp is used for a large amount of illuminations.

The 3rd, such as the true form (design) of lighting apparatus housings such as vertical illumination may since the thermovent obstruction cause overheated, thereby reduced the output of lamp tube service life or light, perhaps influenced the original rigid line wiring of luminaire and the too early damage of control device in the worst case.

The 4th, if when coming bulb retrofited with compact fluorescent lamp, additional and dazzle that do not expect to have may be introduced into these and be equipped with according to such as the focus of the GLS lamps such as vertical illumination of concealed light (darklighter) type and in the lighting apparatus of specially designed reflection shield.

The 5th, be used for a lighting apparatus when light being exported comparable compact fluorescent lamp, and this equipment is when comprising the reflection shield that is made of one that the light of produced orientation of original focus design according to GLS lamp or incandescent reflector lamp controls, when the light output under adopting this reflection shield design of GLS lamp that itself and standard are packed into or incandescent reflectoscope is compared, this compact fluorescent lamp will produce inadequate illumination on working face.

The 6th, though compact fluorescent lamp can obtain large-scale colour temperature, its tone index (colour rendering index) still is lower than the tone index of incandescent lamp.

The 7th, change the light output of small fluorescent lighting apparatus if desired, because adapter can not be general for the lamp of different wattages, thereby must replace whole lamp and adapter (if two).

The 8th, the environmental treatment of fluorescent lamp still is a problem that harmfulness is arranged, and also shows that it is not main (concentrating) users of recyclable trace element of many kinds simultaneously.

For by doing minimum adjustment or do not adjust, the replacement lamp system that can replace in the lighting apparatus of GLS lamp or incandescent reflector lamp exists needs.

The present invention has developed the adapter of the special compression of a class scope that comprises electronic component so that reduce to ELV at the A.C. supply voltage at output lamp socket place.The true form of adapter does not produce interference to the illumination functions of original lighting apparatus, and with an ELV lamp that suits, lamp socket and/or reflection shield or other annex additional or that make integral body, adapter can provide improved illumination efficiency and effect, lower work capacity demand, the lamp life-span of prolongation and the colour temperature of Geng Gao than GLS lamp or incandescent reflector lamp.Summary of the invention

Provide the adapter that is used for common A.C. supply voltage lamp socket according to the present invention a broad aspect, it comprise a common A.C. supply voltage lamp holder be used for mechanically with electric on be connected the common A.C. supply voltage lamp socket of common A.C. supply voltage lighting apparatus; One is contained in the described adapter and is connected and is used for the output of the A.C. supply voltage of described lamp socket is reduced to the potential device of the spendable voltage of an extra low voltage lamp on electric with described lamp holder; And one be connected on electric with described potential device and be used for mechanically with electric on be connected the ultralow pressure lamp holder of extra low voltage lamp, wherein, described adapter is made such shape, make it can comprise described potential device fully and when not having common A.C. supply voltage lamp to be connected on this place and the boundary and the chamber of common A.C. supply voltage lighting apparatus match, thereby in the time of in extra low voltage lamp being installed to described ultralow pressure lamp socket, the focus of extra low voltage lamp will be continued to use and the identical position of being used by original common A.C. supply voltage lamp in common A.C. supply voltage lighting apparatus of theoretical focal point approx.

The a certain position that this adapter can be adorned thereon is provided with locating in the shell of lamp holder, and another position and potential device that the ultralow pressure lamp socket is located on the shell also are arranged in shell.Thereby lamp holder, potential device and ultralow pressure lamp socket are preferably being folded another ground placement minimizing with one of stacked system and are being made the required quantity that is connected electric wire of adapter work, because any unnecessary wiring can cause voltage drop and unnecessary living heat problem.

The shape that can design adapter especially makes it to form an air-gap between the shell of adapter and ultralow pressure lamp socket, particularly the shell of lighting apparatus and the boundary of adapter wherein is housed and chamber between form air-gap.Thereby this air-gap promotes circulation of air and cooling thereafter to help to be subjected to effective work of the adapter that lighting apparatus limits to.

The potential device of adapter preferably includes the leptosomatic transformer of a high frequency ferrite, attaches necessary electronic and electrical equipment again, thereby common A.C. supply voltage is converted to the voltage that has the extra low voltage lamps power supply of different wattages to a series of.

Though, the light of extra low voltage lamp is concentrated thereby can in adapter, be positioned at or load onto an auxiliary reflection shield near the place of extra low voltage lamp as long as replace the lamp adaptor of A.C. power supply just can work effectively with the extra low voltage lamp of packing into.Reflection shield can be contained in be positioned in the adapter or near the dress extra low voltage lamp point on seal extra low voltage lamp thus basically, thereby most of light that lamp is sent obtain the reflection.Another kind of way is, reflection shield can join in the special extra low voltage lamp, is commonly referred to as the reflection shield with pre-focusing.Make its each the special A.C. supply voltage lighting apparatus of to pack into obtain the optimal illumination performance in order to modulate adapter well, can be contained in reflection shield reflection shield is moved forward or backward, thereby focus and change the distribution of light of extra low voltage lamp.

Adapter can be made certain shape, and the boundary of various existing lighting apparatus that makes it to pack into, and adapter can be made certain shape in one aspect of the invention is among the boundary and chamber of the existing vertical illumination equipment that makes it to pack into.On the other hand, adapter can be made definite shape and makes it to pack among the boundary and chamber of existing local lighting equipment.Aspect another, adapter can be made definite shape, among the boundary of the traffic lights that make it to pack into.Also having on the one hand, thereby adapter can be made definite shape make it to pack into the space much at one that taken by the general applications lamp and be used to replace the GLS lamp in the lighting apparatus except that vertical illumination and local lighting.

When adapter was made into the shape that is used for vertical illumination, the center of adapter shell can laminated type is settled and be positioned at substantially to lamp holder, transformer and ultralow pressure lamp socket.In addition, electronic component can actual placement or is arranged in the either side of the printed substrate that is in adapter shell, and high frequency transformer is positioned at opposite side, and particularly, printed substrate is near that side of ultralow pressure lamp socket.Transformer and electronic component preferably are positioned at the not homonymy of printed substrate.

When adapter was made the shape that is used for local lighting, lamp holder, transformer and ultralow pressure lamp socket can stacked arrangement and are contained in the both sides that the center of adapter shell and transformer and corresponding Electrical and Electronic element are physically located in printed substrate substantially.Summary of drawings

50 molded blade preferred forms of the present invention on adapter

At first with reference to figure 1, can see that vertical illumination adapter embodiment of the present invention comprises that one has Any shape be used for packing into the A.C. power supply lamp cap device 1 of existing A.C. power supply lamp socket (not shown).In fact shell 2 is connected on the A.C. power supply lamp holder and provides a suitable shell to be used on this shell printed substrate electronic component being installed at a 2a.Second 2b of shell forms a shell to hold and the thin tube-like high frequency transformer that contacts on PCB is electric.Thereby whole electronic building brick can internal wire contacts on electric with the A.C. power supply between PCB and the lamp holder by being connected in.Shell 2 provides ELV lamp socket 3 at second 2b, and in fact lamp socket 3 links to each other with shell 2, and does being connected on electric by the internal wire and the output of transformer.

Shell 2 can comprise and in fact is connected in the 2a of first on the A.C. power supply lamp holder and in fact is connected in second portion 2b on the ELV lamp socket, thereby first and second portion can be press-fitted or be combined together to form single integral body by diverse ways when production.The integral body that obtains preferably provides firm, an actual adapter that is easy to accurately be processed into required size that connects, and also can make the PCB fix in position.In other words, shell 2 can form single whole or fill by epoxy resin or similar substance or stay can pack into the fully space of

electronic component

7,8,9 of the next one; Or above-described combination.

If use one to be processed or the shell of filling, when first and second parts of shell being connected together or be in manufacturing, A.C. power the input position of lamp holder to the PCB and the ELV lamp socket go up being electrically connected of out splice going splice to PCB and can pass through whole line, press-fit terminals or be suitable for providing other that be electrically connected to be electrically connected method.

Electronic component can carry out surperficial installation or manual welding or suitable PCB be used the combination of these two kinds of methods suitable PCB.Though for conserve space can be contained in reverse side with some element, all Electrical and Electronics connect a side that can be made in plate.In other words, can use two-sided PCB with similar components configuration.

Suitable ELV lamp 6 is installed in the ELV lamp socket 3 that is connected in shell 2.

The shell of adapter has several special design features.Thereby the big groove 24 in molded shell 2a makes the recessed whole height that reduces adapter in situ of the A.C. power supply lamp socket half of adapter.

To be illustrated further feature with reference to follow-up figure:

With reference now to Fig. 2,, can see that adapter is contained in the concealed vertical illumination lamp 47 of a standard.A.C. the connector 11 of powering is visible (normally a rigid line connect terminal box or similar connector) and be connected on the A.C. power supply lamp socket 12 with lead in turn.Vertical illumination lamp 47 has the normal structure that comprises a framework or shell 13, by ceiling folder 14 is installed and it can be fixed in the ceiling recess and the flange of the reflection shield 16 of vertical illumination lamp is close on the ceiling material 15.Reflection shield is fixed in the shell by the effect of elasticity folder 17.

The shell of concealed vertical illumination lamp can be changed to several

different profiles

13, and 13a and same reflection shield 16 also can be varied to head configuration 16a, 16b; Yet the essential structure between reflection shield, A.C. lamp socket and common GLS lamp position remains unchanged substantially.

For adapter of the present invention is encased in the vertical illumination lamp, at first remove standard GLS lamp or incandescent reflector lamp (if dress), allow then standard vertical illuminating lamp reflection shield 16 is left behind and made it break away from spring clip 17 and pull down fully from elasticity folder 17.The shell of vertical illumination lamp (framework) keeps in the recessed ceiling and just removed GLS lamp or incandescent reflector lamp concerning rigid line.Now adapter is packed in the lamp socket 12 and with the way fix in position of machinery, and be connected on electric with lamp socket by lamp holder 1.Replace the origin-location that standard vertical illuminating lamp reflection shield 16 occupies in the vertical illumination lamp housing 47 now.The adapter of dish, shell that part of that particularly comprises the very big transformer of volume 9 can make it to be suitable for to be positioned at A.C. power supply lamp socket 12 in the vertical illumination lamp, the space that can get between vertical illumination reflector of lamp 16 and the vertical illumination lamp housing 47, and do not influence the global design feature of heat radiation crack 10 or other concealed vertical illumination lamp.

Now ELV reflection shield 4 is connected on the adapter shell 2 and will suitable ELV lamp pack into be included in electronic component in the adapter shell do mechanical or the ELV lamp socket that is electrically connected in.

The physical appearance of reflection shield 4 is designed, the light that sends with control and accurate guiding ELV lamp, thereby corresponding to the design characteristics simulation of original common vertical illumination reflection shield 16 or improve the effect that original GLS lamp or incandescent reflector lamp are produced.

By using adapter of the present invention instead, disturbing minimum and again under line or the situation, just can convert the standard vertical illuminating lamp to extra low voltage lamp simply the vertical illumination lamp repacking of adopting standard GLS lamp or incandescent reflector lamp.The result has saved considerable electric power, prolonged the life-span of lamp and has reduced maintenance and heat.

These illustrate the common GLS lamp 20 in vertical illumination lamp Fig. 3 A with reference to figure 3, compact fluorescent lamp 22a and 22b in identical vertical illumination lamp Fig. 3 B, and the adapter of the present invention 2 in the 3rd identical vertical illumination lamp Fig. 3 C.All diagrams have all illustrated their relevant work positions in such standard vertical illuminating lamp.Noticeable feature is air-gap or the heat radiation ditch that is arranged in the vertical illumination lamp (A and C) of GLS lamp and adapter lamp, and obviously lacks heat radiation in compact fluorescent lamp (B).This heat problem often causes the breaking-up of the internal electronic element of the too early damage of lamp or small adapter 22a.

When using together with GLS lamp 10, the design illumination performance feature of 3A vertical illumination lamp (parts 47 and 16) also is the most tangible.One to avoid seeing directly that with normal visual angle it is an essential characteristic that light source obtains dazzling the eyes the sharp cut-off angle of high light under light source.Reflection shield 16 is designed to when the zone 19 that produces relative low-light level when normal visual angle is seen.(therefore getting the generic name concealed light).In a part of the present invention that is suitable for vertical illumination lamp Fig. 3 C, this two kinds of design features have been kept.And be improved by ELV reflection shield 4.When vertical illumination lamp Fig. 3 B uses compact fluorescent lamp 22 instead, the also complete obiteration of these features, see directly a bright light source obtains dazzle the eyes high light and light lack fully directed control replacement work is made finish very poorly and change the scheme of parts also can not be satisfactory.

With reference now to these figure of Figure 4 and 5, demonstrate preferable " dish " and the structure of the adapter shell of the vertical illumination lamp that is suitable for most packing into.Shell is made of two parts 2a and 2b.But show a dark groove 24 among the figure so that reduce its whole height in the recessed adapter shell of A.C. lamp socket part and like this in adapter is packed the vertical illumination lamp into the time.Be designed to (see figure 2) generation circulation of air mouth when the standard reflection shield of vertical illumination lamp is in place at visible molded blade 50 (seeing Fig. 5 B and 5C) on the bottom enclosure 2b, and hot-air is taken away from adapter.(see Fig. 2 even on behalf of the reflection shield opening, dotted line 49 be projected in the figure on the adapter base 2b and the reflection shield head is shown for words littler or higher type, 16a and 16b) how this profile form air heat radiation ditch or crack, and blade 50 also helps adapter is packed in the A.C. lamp socket by fingers is provided.Thereby the molded blade at top much lower for different reflection shield framework (seeing Fig. 2,13a and 13b) all can form the space but they still help the heat radiation.Main heat be produce by ELV lamp 6 and this heat directly reflects by the ELV reflection shield (seeing Fig. 2 label 4) that does not show among this figure and the reflection shield of flowing through around and the convection current that forms of the air of process adapter shell dissipate.By also can cooling off to the direct transfer of heat of the transmission of ELV lamp socket by the heat radiation air-gap 10 that between the back side of ELV lamp socket and shell, forms from the ELV lamp.The little heat that is produced by internal electronic element keeps cooling by the very big air space and the very most cooling blast of design flow through the adapter top layer of adapter shape inside.Be arranged in the situation of the shell of being filled by epoxy resin at electronic component, this epoxy resin plays heat sink effect to shell.

The another one advantage is because actual ELV adapter and ELV lamp are more effective, when the light of the same quantity of remodeling back generation or more for a long time, with electricity be less than original GLS lamp or incandescent reflector lamp, and come an incandescence to produce because heat mainly is electricity consumption, the heat that produces in this lighting apparatus still less.So, after retrofiting by the present invention because be added on external refrigeration system and the existing hard-line connector heat still less, therefore original lighting apparatus becomes colder.

Fig. 6 illustrates the common trait of the more small-sized style 6B of the adapter shell 6A that is used for the vertical illumination lamp and local illumination type.Unique main distinction is that vertical illumination adapter 6A dispels the heat with integrally formed shell, and the 6B of local lighting type be with air ditch grooving 10 make cold air be able to by.Can use with their combination or both.

The obvious characteristic of another of two adapters be between common A.C. power supply input voltage and the ELV output be electrically connected very close to.This near having avoided existing ELV rigid line to connect the voltage landing that lighting device is run into.

The very light in weight of adapter means A.C. power supply lamp socket is caused very little mechanical deformation.In addition, be that power supply or toroidal transformer come compared with the common transformer that is generally used for rigid line connection ELV illumination, electronic transformer can be realized best low-power consumption rate.

With reference now to Fig. 7,, it shows the part section detail drawing of the principal character of cylindrical adapter.Provide with the A.C. lamp socket and make device electric and that machinery contacts by use connecting A.C. power supply lamp holder 1 in the adapter, this lamp holder is used for the conversion electric power electric current and becomes electronic component 7,8,9 adapter shells 2 of ELV continuous with comprising; One ELV lamp socket 3; One ELV lamp 6; With a suitable reflection shield of selecting for use 4.Adapter shell is made up of two parts, and 2a has when molded the cooling bath 10 that forms and 2b has be used for installing additional thermal insulation layer or annex (referring to the figure of back) on 5, ELV lamp socket 3, ELV lamp 6 and have the structure of the reflection shield 4 of focus control 25.As long as can having Any shape, reflection shield can finish that light intensity doubles or light control to the ELV lamp that replaces different GLS lamps and incandescent reflector lamp.Reflection shield can be that metal, glass, plastics or other suitable material are done; It can be processed or make in order to help the output of control light.If reflection shield also can be designed to have glass surface, lens or disperse or reflection unit when having this to need.The actual light output that finally obtains is controlled even can is above all combinations.Compound waterproof glass reflection shield can do with the striking resemblances of PAR38 lamp.

Fig. 8 illustrates GLS lamp Fig. 8 D and incandescent reflector lamp Fig. 8 A, and in compact fluorescent lamp Fig. 8 C and 8F and the local illuminating lamp two kinds common forms, promptly general tubulose local lighting lamp 26, and cylindrical adapter Fig. 8 B and 8E in the closed local lighting lamp 27.Principal character comprise in order to cooling local lighting lamp 10 and the hole, the adjustable A.C. that are provided with at the rear

portion lamp socket

With reference to local lighting lamp Fig. 8 A and 8B and Fig. 8 D and 8E the actual ability that replaces GLS lamp and incandescent lamp in the finite form of the lighting apparatus of adapter is described fully also, and other local lighting lamp Fig. 8 C and 8F also illustrate the unsuitable remodeling with compact fluorescent lamp.

Fig. 9 is the perspective view of cylindrical adapter.Reflection shield 4 moves so that lamp 6 focuses on or defocuses along rectilinear direction.And this has changed beam propagation.Adjusting device 25 can be by threaded keyhole formula shift position, and provides along rectilinear direction sliding reflection mirror or lamp or other moving method that can focus between speculum or lamp.

Figure 10 has represented and will have been replaced and make living main GLS lamp of its light characteristic and incandescent reflector lamp by adapter design.All lamps all can obtain in worldwide, and they have the very big wattage of multiple supply voltage, scope, lamp holder shape of all kinds, and that the bulb shell has is transparent, opaque, reflective mirror is arranged, textured and other a large amount of versions.

Inner electronic circuitry design becomes not consider how the load of lamp can control some output wattages with constant secondary voltage.For example, when the output of using 12V, can use from 10 to 100 watts lamp and needn't change electronic circuit.

Figure 11 illustrates the length corresponding to lamp, and the adapter of two kinds of preferred versions allows to obtain the reason of relevant focal position much at one.Drawn line 23 has been pointed out the approximate location of focus.

Figure 12 illustrate reflection shield 4 along rectilinear direction move with the ability (focus of lamp 6 remains unchanged with respect to the position of shell 2) that changes focus in addition reflection shield can mix single glass UV (ultraviolet) optical filter or lens or other device and do additional control with reduction or other desired characteristic to distribution of light or high light.

Figure 13 and 14 illustrate will design the reflection shield the same with the incandescent reflector lamp illumination performance of RO80 move vertically one apart from 4.975mm (14.725mm-9.750mm) changes the effect of distribution of light, is become a slice light of broad by an arrow beam of light according to polar curve 29.The fineness of noting the reflection shield surface also can influence light control.

Figure 15 is illustrated in the adapter that 5 places have available reflect heat device 35 and special ELV lamp 36 and the lamp socket 37 that matches.Notice that this special lamp itself has the prefocus reflection shield of interior dress, so without any need for the reflection shield of selecting for use 4.

Figure 16 illustrates and is applicable to the direction next door guiding that connects A.C. lamp hole seat or the adapter of divergent rays.Cover or local reflection shield 38 can be that metal, glass, plastics or other material that is fit to are done.

Figure 17 illustrates adapter that cloche 39 or other material are housed with along special direction or shape is dispersed and or guiding light.This cloche can be opening or sealing, and can do equally with the shape of lamp of element 33 among Figure 10.
