Description
Technical field
The present invention relates to a kind of LED light source, particularly a kind of LED light source module for advertisement lamp-decorated painting be made up of several LED lamp bead.
Background technology
Explanation of nouns:
1, advertisement lamp-decorated painting (Illuminated character): the outdoor advertising that a kind of scale of construction is very large, usually wide up to tens meters, tens of rice, generally represent on construction site scaffold and skin.Daytime, people can see the character pattern on advertising painting picture by daylight; The light that send by the LED or lamp bar that are arranged on this character pattern periphery or key position in the evening, people see this character pattern as daytime.
It mainly contains two kinds of structures:
The first is by advertising spraying cloth and electric light source colligation in expansion and on the plastic net hung up or wire netting: specific practice is covered by advertising spraying cloth on plastic net or wire netting, on advertising spraying cloth after Durchgangshohle, with commercially available nylon cable tie colligation on the plastic net of basic unit or the graticule of wire netting, after advertising spraying cloth is fixed on plastic net, after the character pattern edge Durchgangshohle that institute's air brushing manifests on advertising spraying cloth again by LED module or the commercially available nylon cable tie of lamp bar together with advertising spraying cloth colligation on the plastic net of basic unit or the graticule of wire netting, thus form one by advertising painting picture, LED module or lamp bar, the lamp-decorated painting that plastic net or wire netting are formed jointly, Illuminated character.
The second lamp-decorated painting, Illuminated character way are: the patent of invention (patent No. is 201220127940.3) that the applicant obtains previously.It is advertising painting car note, single hole thoroughly or the advertising sticker back side be provided with the material of adhesive sticker bonding agent, pasted on glass curtain wall or other smooth building surface (as smooth exterior wall) again, then adhesive sticker is set at LED module or lamp bar bottom surface, again this LED module or lamp bar are pasted onto above-mentioned advertising painting car note, single hole is saturating, the character pattern edge on advertising sticker.Thus form one by advertising painting car note, single hole thoroughly, lamp-decorated painting, Illuminated character that advertising sticker and bonding LED module are thereon formed.
2, LED module formula Mini-lighting equipment:
It is little as volume, price is low, mounting arrangements is convenient, is widely used in the industry such as advertisement, decoration, and they are installed on the profile of described advertisement lamp-decorated painting usually, manifest the character pattern in this advertisement during for lighting.Be installed in some grooves in decoration industry, hide illumination for ceiling or some indoor shapes when lighting.When above-mentioned occasion is used, be usually that the continuous arrangement of tens meters, up to a hundred meters uses.
The LED light source for advertisement lamp-decorated painting, Illuminated character commercially available at present roughly has several as follows:
1) the LED plastic-packaged fluorescent tube (also known as LED rainbow tube) such as large two wires, the strategic hinterland areas of China, circle two wires.
Characteristic is summarized: adopt bare conductor directly LED lamp bead to be coupled together in mode in parallel again of first connecting, then be packaged in transparent plastic, usually, its specification is more than hundred meters, operating voltage is AC220V, during use, cutting can minimum length must more than 2 meters.
Advantage:
Surrounding edge (surrounding edge refers to and uses LED light source to lay round the profile of described character pattern) can be carried out with it to the profile of character pattern in described advertisement lamp-decorated painting very easily to arrange, now, only need power at the two ends of this fluorescent tube, thus, more power supply wire rod can be omitted.Because rated voltage is high, whole section of light tube electric voltage decay (line loss) is minimum, thus, makes the LED lamp bead emission uniformity on it good.This LED light source is linear light sources (linear light sources refers to that the LED light source of formation is the light source of strip), and it is conducive to sketching the contours described profile and light loss is less.
Shortcoming:
Supply voltage is high, and between LED lamp bead, bare conductor connects, and for guaranteeing safety, usual outside need encapsulate thicker plastic material, therefore, causes such fluorescent tube body weight, pliability not and the defect such as mount stress is large, is especially easily twisted off inner lead at small turning.
During outdoor use, do not work because pneumatic reason easily causes inner broken string to cause this fluorescent tube multistage, can occur because short-circuit fire causes major accident time serious.
Because every root is longer, when using it to character pattern surrounding edge, more (the minimum use amount of such fluorescent tube is for more than 2 meters) are saved at surrounding edge rear, therefore, whenever unnecessary go out part also need to use opaque material to be wrapped up, in case the light that this section of redundance sends affects normal display effect, but also trouble and waste.
Possessor is by reducing supply voltage to the greatest extent, reduces modulus (namely described minimum use amount) and improves its performance, but poor effect.The operating voltage of usual LED lamp bead (light emitting diode) is between DC2.4V ~ 3.6V, above-mentioned LED rainbow tube adopts series connection tens LED lamp bead in the modulus length of 2 meters, equilibrium assignment is born to these tens LED lamp bead by the terminal voltage of its 220V, therefore it must be a modulus with longer 2 meters, just can guarantee that LED lamp bead wherein normally works.If want to reduce modulus length, then more LED lamp bead of must connecting in the modulus after reducing length carrys out dividing potential drop, otherwise when being overlapped in the terminal voltage circuit of 220V, in this modulus, all LED lamp bead will be burnt because of overtension.Another mode is exactly reducing the electric resistance partial pressure that in the modulus after length, mixed resistance of taking series connection some is higher, LED lamp bead and divider resistance can be caused so again too intensive, generate heat high, safety coefficient is lower, and due to resistance too much cause power consumption larger.
2) round die block of oxeye or rainbow semicircle is commonly called as.
Characteristic is summarized: by 6 to 11 LED lamp pearls series connection around to be arranged on circular circuit board and the diameter of inserting recording quantity is about in the round plastic box of 40mm, adopt DC24V as the terminal voltage of this generic module, connected by wire between module, usually its specification is serially connected for several round die blocks, mostly be most tens, because its supply voltage is lower, connected the electric energy making consumption at most on wire excessive, namely line loss is excessive.
Advantage:
Because module individuality is less, can utilize turning for electrical connection electric wire between module at the place of talking in a roundabout way, module itself can not bear bending stress, not easily causes mechanicalness to damage.Supply voltage is low, and electrical security is good.For the LED lamp bead (diode of different glow color of different glow color, its operating voltage is different), the LED lamp bead number of suitable quantity is adopted to carry out dividing potential drop 24V, without the need to or less series connection divider resistance, therefore the LED lamp bead in module works when rated operational voltage substantially, therefore, its luminous efficiency is high.
Shortcoming:
Can find out that it is spot light (namely multiple LED lamp bead is around concentrating in a less border circular areas) from the shape and structure of above-mentioned module.When using it for the surrounding edge to character pattern profile, just need densely arranged for several such round die blocks effect that could embody overall uniformly light-emitting, reach the object illuminating advertisement lamp-decorated painting, thus, on the character pattern profile of unit length, then need this large amount of LED round die block of arranging.One, causes the waste of source material; They are two years old, because its every tens these generic modules of reason of voltage attenuation (line loss) just need access power supply, the too intensive powering mode causing its low-voltage and high-current of LED lamp bead in unit length simultaneously, wastes a large amount of for the electric wire and cable material for its larger cross-section of powering; Its three, the fixing little module one by one of colligation is also wasted time and energy, and productivity ratio is low.
In fact adopt the technology of above-mentioned electric light source to make Illuminated character, lamp-decorated painting, although, safety more reliable than aforesaid LED rainbow tube, its material and cost of labor want much high.
3) rectangular LED module (module).
Characteristic is summarized: three LED lamp pearls and a divider resistance are connected in series and are arranged on rectangular circuit board, this circuit board being inserted one is about in 7cm, the plastics of one side opening of wide about 1.2cm or can again, adopt DC12V as the terminal voltage of this generic module, wherein, under every LED lamp pearl can be operated in rated voltage.Usual specification is serially connected for several modules, mostly is 40 most for a string, is connected between module by wire.Because its supply voltage is very low, connect too much voltage attenuation (line loss) serious, in fact during its 40 a string uses, guarantee pressure drop of must powering at the two ends of each module is unlikely to excessive.
Advantage:
This single module is equivalent to a bit of linear light sources being about 7cm, when module is connected in series one by one from beginning to end, (serial connection that this place claims refers to structural, side circuit relation is parallel circuit, namely the suffered terminal voltage of each module is consistent) time, it is equivalent to only have a row LED lamp bead on linear direction, under the prerequisite ensureing light continuous uniform, the LED lamp bead needed in unit length compared with above-mentioned round die block will be lacked a lot, has saved source material.Because its size is less, can utilize turning for electrical connection electric wire between module at the place of talking in a roundabout way, module itself can not bear bending stress, not easily causes mechanicalness to damage.
Shortcoming:
Every three LED lamp bead just need access divider resistance, and electric energy becomes thermal waste, thus overall light efficiency is lower; Operating voltage is too low, when the long string of multiple module uses, because voltage attenuation (line loss) is serious, need every about 20 modules just access feeder ear, be again the pattern of low-voltage and high-current, waste is a large amount of for the electric wire and cable material for its larger cross-section of powering; Individual module specification is less, wastes time and energy when colligation is fixed, and production efficiency is low; Rectangular plastics or can are hardware structure, weak mechanical strength, and usually fractureed damage in Illuminated character, lamp-decorated painting transport, installation process.
4) flexible LED lamp bar or light bar.
Characteristic is summarized: some LED lamp bead arranged in a series arrangement and be arranged on FPC (flexible PCB), reach waterproof effect in its outer cover with lucite pipe, also it all wraps with waterproof by useful transparent watertight glue.During use, adopt following two kinds of modes:
One, when terminal voltage uses low-voltage power supply, is cut into the lamp bar of length between 30cm ~ 100cm by such soft lamp bar or light bar, under making LED lamp bead wherein be operated in rated voltage as far as possible with this.
Its two, when terminal voltage uses 220V to power, can select the length setting of this soft lamp bar or light bar more than several meters.
Advantage:
Above-mentioned two kinds of modes are linear light sources, design suitable LED lamp bead luminous efficiency higher.
Shortcoming:
One, voltage attenuation is large, owing to being connected by the copper-clad of FPC circuit board between the LED lamp bead in such soft lamp bar or light bar, and copper-clad sectional area is less, its resistance is just relatively large, no matter be that many low voltage power supplies are connected in series the shorter soft lamp bar or light bar that are connected, or the very long soft lamp bar of mains-supplied or light bar, its supply current is all by the longer copper-clad in path, LED lamp bead wherein and circumscripted power line form electric loop, electric current can consume a large amount of electric energy (pressure drop namely consumed on the line is excessive) through this copper-clad, under making wherein numerous LED lamp bead usually be operated in low voltage condition, cause its luminous efficiency lower, therefore, this defect is overcome if want, just need to introduce a power supply port (only for low voltage power supply) every several soft lamp bars or light bar, like this, the power supply wire rod and causing needing again to configure a large amount of peripheral hardware is powered the waste of wire rod in a large number.
They are two years old, FPC (flexible PCB) is the material of extremely frivolous fragility, for the radiating effect making lamp bar have, the lucite pipe or the transparent watertight glue that wrap up it just can not be too abundant, so the mechanical strength of this flexible LED lamp bar or light bar is very low, at once bring electric fault after damaged by mechanicalness, short-circuit fire or open circuit do not work (220V for electric light bar more so).
In fact, use this soft lamp bar or light bar and fail to be used in Illuminated character, lamp-decorated painting field, but the field such as show window, interior decoration that is used in is as floor light.
Although visible above-mentioned electric light source technology seems simple, but be limited by voltage, the current characteristics of diode (or claiming LED chip), the line loss pressure drop of power supply, the mutual restriction that the functional requirement of line source, the requirement of size modulus, structural strength, light efficiency are energy-conservation etc., design a kind of good electric property, geomery is applicable to, mechanical strength is high and cost the is low LED electrical light source for Illuminated character, lamp-decorated painting still needs breakthrough.

One (for preferred embodiment of the present invention), the end line 6 of the power line 4 of last bar LED light source module 10 and the corresponding power line 4 of another LED light source module 10 adjacent connect, and (namely positive pole connects with positive pole, negative pole connects with negative pole), the like, then form the LED linear light sources be made up of many LED light source modules in parallel.In which, the terminal voltage of all LED light source modules is identical and be DC low-voltage.Positive and negative terminal electrode due to all LED light source modules is connected by the RV cable that the larger resistance of sectional area is very little, so, its voltage line loss is less, and the number of LED lamp bead 31 in every bar LED light source module 10 is 7-15 (and few), length is not at 15cm-25cm (oversize), therefore, the electric energy loss flowing through copper-clad wherein can be ignored, thus, under the LED lamp bead 31 can guaranteeing in every bar LED light source module 10 is operated in its rated voltage, the luminous efficiency of every LED lamp bead 31 is made to be in higher level.In addition, if wherein certain LED light source module damages, other LED light source module work can not also be affected.
They are two years old, the power line 4 that one butt line 6 of the power line 4 of last bar LED light source module 10 is contrary with the electrode of another LED light source module 10 adjacent connects (i.e. positive pole connect negative pole or negative pole connects positive pole), the like, then form the LED linear light sources be composed in series by many LED light source modules.In which, the terminal voltage of all LED linear light sources is suitable for using 220V voltage, although, its voltage line loss is higher, but comparatively prior art, the linear light sources good toughness (bending property is good in transformation corner, not frangibility) of which, and, because its moderate length is saved few at surrounding edge rear.
The present invention adopts the circuit substrate that FPC (flexible PCB) is this module, circuit substrate is embedded in the groove body 11 of the described base body 1 made with the low flexible plastic of elastic modelling quantity or rubber, the power line 4 being placed in positive wire casing 12 and negative wire groove 12 enters from one end of base body 1, draw from the other end, every side power line 4 has the circuit on pad and circuit board to be formed to be electrically connected on FPC (flexible PCB).This structure brings benefit to be: first FPC (flexible PCB) is extremely frivolous, deposited copper circuit on it be printing or calendering all very thin, that is the cross-sectional area of conductor of copper-clad is actively little, resistance is relatively large, namely no matter be soft lamp bar or module in prior art, the access of power line 4 and to pick out be all a little two ends at this soft lamp bar or module, electric current needs to rely on the deposited copper circuit on circuit board by the transmission of this soft lamp bar or module, thus cause line voltage distribution loss, the present invention makes power line 4 run through module from two ends, add cross-sectional area of conductor at low cost to amass, decrease line loss pressure drop, thus overcome low-voltage LED soft lamp bar can not the disadvantage that uses of multiple long string, in addition, the circuit substrate that the FPC (flexible PCB) that the present invention because employ can bend is module and have that elastic modelling quantity is low and described base body that is that be made up of flexible plastic or rubber is also the RV cable that can bend to the power line 4 laid in the support of this circuit substrate and the positive wire casing 12 on the two side of groove body 11 and negative wire groove 12, whole module just becomes to have and can bend and don't flimsy architectural feature, firmly crisp unlike LED module of the prior art, easily fractureed damage, solve a difficult problem for modular structure intensity cleverly, so, it is longer that module just can make size, arrange the line source of more LED lamp bead 31, instead of the circular many lamps pearl spot light of DC24V of 4cm or the DC12V power consumption light source of the long only rectangle three LED lamp pearl 31 of 7cm can only be about with diameter, why these two kinds of prior aries can not make longer linear light source module, because they are firmly crisp, for Illuminated character, the huge necessary convolution transport of this scale of construction of lamp-decorated painting and the application scenario of installing, long and narrow and firmly crisp module is very easily fractureed damage, wind load when using out of doors also can damage its structure, again, because FPC (flexible PCB) mechanical strength is low, described base body 1 protects it can not by overflexing effectively, being arranged in positive wire casing 12 and negative wire groove 12 power line 4 also protects whole module excessively can not be elongated (power line 4, because of the copper cash of its inside, has less extensibility compared to soft base body 1) effectively.
Further improvement of the present invention is in described groove body 11, be provided with the water proof and dust proof glue 8 that FPC substrate 2, power line 4 and circuit of light sources 21 can be covered.It not only plays water proof and dust proof effect, but also this module can be made to form a complete body, improves the intensity of this module further.Marine glue is also soft, and whole module still can bend.
In the application scenario for Illuminated character, lamp-decorated painting, supply voltage of the present invention selects the safe voltage between DC24V to DC48V, module cut to lengthen is at below 25cm, in the LED lamp bar 3 of LED light source module of the present invention, need not to connect as prior art several divider resistances, at most (power of this divider resistance may diminish to 0.018W to the divider resistance that only increase resistance is very little in every root LED lamp bar 3, and 7cm white light module resistor power of the prior art is generally 0.081W, and 3 LED lamp bead just need configure series connection divider resistance).Flexible LED lamp bar in the present invention compared to existing technology or light bar or round die block, the divider resistance much less of serial connection, power consumption is little, and light efficiency is naturally just very high, also just more energy-conservation comparatively speaking.
Module cut to lengthen of the present invention is at below 25cm, the needs considering LED lamp bead 31 spacing and practical modulus, if single module is long, then known by technical Analysis above, modulus is larger, to just bad process during character pattern surrounding edge ending in described advertisement lamp-decorated painting, easily longer one section of disappearance can not close and affect light integrality or waste one section of light source also wants coated covering.In the length of 25cm, the pitch arrangement of 7 to 11 lamps, Technological Economy environmental index is reasonable, overstocked then excessively bright, crosses dim at least.
During actual use, many connections of should trying one's best between module use, dozens of a string (adjacent two modules of the present invention being linked together by the end line 6 being arranged on module two ends of the present invention) when both dispatching from the factory, it is parallel circuit relation between module, more than 100 a string, and during both end power supplying, its pressure drop is in permissible value.Illuminated character, lamp-decorated painting when installing and using, more than its access power supply port wants minority doubly compared to 4cm round die block or the microscler module of 7cm, save a large amount of electric wire material, simpler efficient for electrical wiring.
The present invention can apply in the bottom surface of described base body 1 with double faced adhesive tape, when bright and clean smooth place installs, can be easily pasted onto in bright and clean plane, and due to the architectural characteristic of its frivolous softness, can be pasted onto papery, Polypropylence Sheet, painting canvas etc. can on the material of convolution, be easy to carry transport, can not peel off double faced adhesive tape in convolution process because mutual uneven deformation is excessive.(this point has an unexpected effect compared to 4cm round die block or the such hardware modules tool of the microscler module of 7cm).
The present invention adopts the terminal voltage of DC24V ~ DC48V to power, not only safe and reliable, and the module being different from prior art adopts the terminal voltage of DC12V, due to higher terminal voltage, in module, the number of LED lamp bead can be more, therefore, its length also lengthens thereupon, when to described character pattern surrounding edge, need the power supply port of access less, more electric wire material can be saved.
When to described character pattern surrounding edge, preferred following structure:
Single module length is that between 12cm ~ 30cm, (single module is long, surrounding edge rear occurs that the probability that module is saved or is short of is larger, also more easily occur twisting off fault, single module is too short, LED lamp bead is too intensive, and economy is bad), when arranging a row LED lamp bead in this module, number is less than or equals 8, and terminal voltage gets 24V or 27V (as shown in Figure 3); When needing to reach brighter effect, two row LED lamp bead can be set.Often arrange (as shown in Figure 4) in parallel with another after row series connection, often no more than 8 of row LED lamp bead, input voltage gets 24V or 27V again; Also can be arranged in series by two row LED lamp bead, wherein no more than 12 of the number of LED lamp bead, input voltage gets 36V (as shown in Figure 5); Also can be arranged in series by two row LED lamp bead, wherein no more than 16 of LED lamp bead number, input voltage gets 48V (as shown in Figure 6).
When needing the LED linear light sources of composition to have light and shade change or color changeable effect, IC control chip can be added in single modular circuit, now, not only supply lines is had in the connection electric wire at module two ends, also need to add signal connecting line and carry out transmission of control signals, in view of IC chip is of a great variety, physical circuit connected mode is no longer enumerated.
LED light source module of the present invention, have in the making for advertisement lamp-decorated painting (Illuminated character) and be convenient to convolution and not easily twist off, power supply interface saves electric wire material less, the divider resistance that unit length accesses is few, the advantage that light effect is higher, does not have clear superiority in other application scenario.
