Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 6-2 in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, not all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined or explained in subsequent figures.

In the description of the present invention, it should be noted that, if the terms "upper", "lower", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the products of the present invention are used, the description is only for convenience of description and simplification, but the indication or suggestion that the indicated device or element must have a specific position, be constructed and operated in a specific orientation, and thus, should not be interpreted as a limitation of the present invention.

Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

Referring to fig. 1, in one embodiment, the present invention provides an at least three-wire LED module, comprising:

first to nth LED luminous bodies connected in parallel with each other, and a first current limiting unit;

and, a first electrical connection line, a second electrical connection line, and a third electrical connection line;

wherein the content of the first and second substances,

n is greater than or equal to 3;

the first conductive part of the first electric connection wire is connected with one end of the first LED luminous body, and the other end of the first LED luminous body is connected with the second conductive part of the second electric connection wire;

the second conductive part of the second electric connection wire is also connected with one end of the first current limiting unit, and the other end of the first current limiting unit is connected with the third conductive part of the third electric connection wire;

the module is connected with a power supply only through the first electric connecting wire and the third electric connecting wire.

For this embodiment, since only one current limiting unit is used for the first to nth LED luminaries, the above embodiment greatly reduces the amount of current limiting units used. This not only reduces costs, but also reduces the dependence on certain specific current limiting units. This is of great significance for both high and low voltage LED solutions, especially for high voltage LED solutions. For example, when the LED luminary includes only a very small number of high voltage LED chips, even if the module is connected to an external relatively high voltage power supply, the module can still enable the LED luminary to withstand the power supply voltage and emit light, and the current limiting unit further controls the current flowing through the LED luminary, which means: when the current flowing through the LED luminary is very small, for example 0.6-0.8mA, and at 110V, the LED luminary operates at a very low power and is not burned out.

In addition, since the first LED luminary to the nth LED luminary are connected in parallel, this means that: the first LED luminous body to the nth LED luminous body can be connected between the first electric connection line and the second electric connection line. Under the condition, when any LED luminous body fails, the failed LED luminous body can be easily cut off, and the other LED luminous bodies are always ensured to be still in parallel connection through splicing the first electric connecting wire and the second electric connecting wire, so that the module is maintained in the aspect of the connection.

In another embodiment of the present invention, the substrate is,

the current limiting unit comprises any one of the following components: current limiting IC, resistance.

More preferably, the current limiting IC is a constant current IC.

It should be noted that, when the current limiting unit includes a current limiting IC, this is of particular significance for high voltage power supply, because: when a plurality of LED luminous bodies are connected in parallel, each LED luminous body can be the same voltage, and the current and the power of each LED luminous body can be precisely controlled by limiting the current, so that the LED luminous body has the advantage of only precisely controlling the current compared with a series high-voltage scheme in the prior art. That is, the utility model discloses can realize a better: high voltage, low power, low cost, precision controlled LED lighting solutions. In addition, the parallel connection LED illuminating product with longer length is facilitated to be realized, especially, under the condition that the current is limited under the extremely tiny current, as long as the LED can still meet the visual brightness, the tiny current enables the power of each path to be relatively low, on the premise that the total power is fixed, the voltage of each parallel branch circuit meets the equal condition, and on the premise that the total current of all branch circuits is controlled by the current limiting IC, the parallel connection LED illuminating product with longer length can be realized. It will be appreciated that where DC power is used, the first and third electrical connections may be positive and negative supply lines; when AC power is used, the first and third electrical connections may be a line of zero volts.

It is also particularly emphasized that the current limiting IC is preferably a constant current IC. Illustratively, the constant current IC provides 0.6-0.8mA and is at 110V, so that the LED luminary operates at very low power and is not burned out. It can be understood that the utility model discloses a product work just can not be burnt out at 110V equipotential voltage through dispose a certain quantity of LED chips to be favorable to extending the parallelly connected LED illumination of sufficient length. 230V, a similar scheme may be employed.

In another embodiment of the present invention, the substrate is,

the first electric connecting wire continuously penetrates through each side of the first LED luminous body to the nth LED luminous body;

the second electric connecting wire continuously penetrates through each side of the first LED luminous body to the nth LED luminous body;

and the number of the first and second electrodes,

the first electric connecting wire is connected with the first conductive pin of the first LED luminous body; the position connected with the first conductive pin is a first conductive position of the first electric connection wire;

the second electric connecting wire is connected with the second conductive pin of the first LED luminous body; the position connected with the second conductive pin is a second conductive position of the second electric connection wire;

the first and second conductive parts are connected with the first and second conductive pins after the flexible insulating layer of the first and second electrical connection wires is removed in advance.

For the embodiment, since the first and second electrical connection wires continuously pass through two sides of each LED light emitter, and the first and second conductive portions are connected to the first and second conductive pins after the flexible insulating layer is removed in advance, the first and second electrical connection wires of the above embodiment can be completely connected without using two pre-cut electrical connection wires to connect the corresponding LED light emitters on two sides of any LED light emitter. This obviously contributes to an increase in manufacturing efficiency: the first electrical connection wire and the second electrical connection wire are prepared to be long enough, and after the flexible insulating layer of the corresponding conductive part is removed in advance, the conductive part is connected with the corresponding conductive pin of the LED light-emitting body, for example, welding.

Referring to fig. 2, in another embodiment,

the module also comprises an n +1 th LED luminous body to a 2n th LED luminous body and a second current limiting unit;

between the nth LED emitter and the n +1 th LED emitter:

the first electrical connection line is uninterrupted;

the second electrical connection line is open;

the third electrical connection line is uninterrupted.

Therefore, the embodiment achieves the effect of grouping all the LED luminous bodies again according to different current limiting units. Because the capability of a single current limiting unit is limited, the module can have enough length and can still achieve the purpose of reducing the number of the current limiting units to a greater extent. The disconnected state of the second electrical connection part can be cut out to form a notch when the module is manufactured through a machine, and the disconnection is clearly shown in fig. 2.

In a further embodiment of the method according to the invention,

the first and second conductive pins, the first and second conductive positions, the first current limiting unit and the first LED luminous body are all packaged in a package with a certain light transmittance.

It can be appreciated that this protects not only the relevant pins, the conductive sites, but also the current limiting unit and the first LED luminary and avoids as much as possible the influence on the light. Has certain light transmittance, and typically comprises the following situations: transparent, translucent, having a certain hazy effect, etc.

In another embodiment of the present invention, the substrate is,

the first, second and third electrical connection lines have any of the following characteristics:

(1) the flexible insulating layers of the first, second and third electric connecting wires are made of rubber materials or PVC materials;

(2) the first, second and third electric connecting wires are connected with each other through a first connecting part and a second connecting part with insulating property;

(3) the first, second and third electrical connection wires are commonly covered by an insulating layer.

It can be appreciated that the outdoor water-proofing, anti-aging properties of the rubber material all enable the module to be used in more severe outdoor environments. The PVC material can also be used as a selection type of the soft insulating layer. The flexible insulating layer may be a double-layer structure insulating layer.

For this embodiment, the first connection portion, the second connection portion means that there is a definite connection between the first electrical connection line and the second and third electrical connection lines. This obviously improves the overall protective properties of the module, is not easily torn off, etc. As for the first, second and third electrical connecting wires are commonly covered by an insulating layer, it means that the wires can also be covered by an external insulating layer, which is also beneficial to improving the overall protection performance of the module, and is not easy to tear and break.

In another embodiment, the first, second and third electrical connections are substantially parallel. It can be appreciated that this facilitates pre-removal of the flexible insulating layer at the corresponding conductive site, facilitating positioning of the respective electrical connection lines by a tool or robot or the like.

In another embodiment of the present invention, the substrate is,

the first, second and third conductive parts are formed by cutting the first, second and third electrical connection lines through a combined blade.

Typically, the first and second conductive portions are formed by cutting the original insulating layer at a certain position of the first and second electrical connection lines by the first and second blades of the combined blade; alternatively, the combined blade may be two blades, or may be combined with a positioning device, such as an optical or visual positioning device, to position the cutting position, and a robot drives the blade to a target position to cut the insulation layer. Furthermore, the manipulator can further strip the peripheral insulating layer of the conductive part to facilitate the connection between the conductive pins of the LED luminous body and the conductive part.

It can be understood that, in addition to the conventional two conductive pins, one LED luminary may also involve two LED chips sharing a positive electrode or a negative electrode, which involves the third conductive pin in a single LED luminary. Even for one LED light emitter, taking four more complicated conductive pins as an example, the combined blade may cut the corresponding insulating layer at four different positions for multiple times to form the connection points of the first, second, third, and fourth conductive pins. Further, for more precise cutting of the electrical connection wires to remove the insulating layer to expose the conductive portions, an optical or visual positioning device combined with AI technology may be used to precisely position and realize cutting and stripping of the insulating layer.

In a further embodiment of the method according to the invention,

the package has at least any one of the following features:

(1) the outer part of the packaging part can be sleeved with a shaped shell model, and can also be molded outside the packaging part in an injection molding mode;

(2) the packaging piece is formed by packaging glue;

(3) the package is of a substantially spherical configuration.

In another embodiment of the present invention, the substrate is,

the module has at least any one of the following characteristics:

(1) the first LED luminous body and the second LED luminous body can be cut off so as to facilitate the free cutting of the module;

(2) the n and n +1LED luminous bodies can be cut off so as to facilitate the free cutting of the module;

(3) the first LED luminous body at least comprises two LED chips which are connected in series, so that the current requirement of the LED luminous body can be accurately controlled while voltage is divided.

It should be noted that this is particularly significant when the module further comprises a second LED emitter connected in parallel, because: when the front and the back are connected with a plurality of LED luminous bodies which are connected in parallel, any one LED luminous body can be freely cut to adapt to the length requirements of different scenes. Even if one LED luminous body has a fault, the LED luminous body with the fault can be freely cut, and the front and the rear electric connecting wires can be directly connected to facilitate maintenance. The serial connection of the LED chips in the LED luminary aims to precisely control the current requirement of the LED luminary while dividing the voltage.

In fact, the above embodiments of the present invention preferably adopt a scheme of connecting a plurality of LED luminaries in parallel, and in the case of connecting in parallel, each LED luminary can be freely cut, including cutting from between the nth and the (n + 1) th LED luminaries. After cutting, each LED luminous body can meet the requirement of power supply voltage under the condition of being connected with a power supply, otherwise, even if the LED luminous bodies with longer length and more parallel connection are not required to meet the requirement of power supply voltage at first, each path of parallel connection LED luminous bodies can be directly burnt. For example, in a scenario of using 110V-230V ac power supply, each LED luminary itself includes tens of LED chips connected in series or in series-parallel to bear 110V or 230V ac voltage. Even the utility model discloses a LED's module includes 3 LED luminous bodies, cuts arbitrary one LED luminous body, under the prerequisite of the electric connecting wire of keeping this LED luminous body both sides, makes it be connected to under 110V or 230V's the alternating current, as long as this LED luminous body self does not have the trouble, all can form the return circuit and make it luminous. By contrast, a series LED luminary cannot do this, because a plurality of LED luminaries connected in series as a whole can only operate at 110V or 230V, and if one LED luminary is directly cut off and connected to 110V and 230V, the LED luminary will burn out with a high probability. It can be understood that the present invention is not limited to voltages of 110V, 230V, etc., and may be other power supply voltage standards or a wider voltage range.

Therefore, under the condition of parallel connection, the module can freely cut the LED luminous bodies, and after cutting, each LED luminous body can meet the requirement of power supply voltage under the condition of being connected with a power supply. In addition, in the case of LED luminous body failure, the failed LED luminous body can be freely cut out and the original front and rear sections can be continued, under the condition of not losing much length, the LED luminous body can continuously work under the same power supply voltage, and the consistency of the brightness among the LED luminous bodies can be maintained under the current working condition.

In another embodiment, the LED luminary is a patch type. This is more favorable to improving manufacturing efficiency and guaranteeing product property ability.

In another embodiment, the LED illuminator is high voltage. This facilitates the manufacture of high voltage parallel products.

In another embodiment, the present invention also provides an LED lamp, including:

an outer package structure having a certain light transmittance;

the external packaging structure comprises any module.

It can be understood that this is with the utility model discloses a LED module is as an encapsulation object, and holistic encapsulation is: an external packaging structure with certain light transmittance. When the utility model discloses a very little time that the LED module can be made, such LED lamp obviously has its meaning. By way of example, the encapsulation with the colloid can make the LED lamp have a certain light transmittance, such as full transparency, translucency, a certain hazy feeling effect, and the like.

In another embodiment, as shown in fig. 3-1, 3-2, and 3-3, the exposed first electrode wires, i.e., the first electrical connection wires, formed in the cutting region of the blade, the second electrode wires, i.e., the second electrical connection wires, coated with the second flexible insulating layer, in the uncut region, and the first LED luminary are illustrated. The third electrical connection line and the current limiting unit are not shown in fig. 3-1, 3-2, 3-3.

In another embodiment, the light emitting chip in the LED light emitter may also be a high voltage chip connected in series with a non-high voltage common chip. Wherein, the high-voltage chip in the first LED luminous body and the n +1LED luminous body is further connected with the first current-limiting IC and the second current-limiting IC. It can be understood that the LED light emitter may be a high voltage chip, a plurality of high voltage chips, a plurality of low voltage chips, a combination of high and low voltage chips, etc., depending on the voltage of the voltage, and what cost requirement.

In a further embodiment of the method according to the invention,

the current limiting unit may not be packaged in a package with the LED emitter. For example, the first current limiting unit is packaged separately, or the first current limiting unit is packaged together with a conductive site in the vicinity thereof.

For various packaging scenarios that may be involved with this embodiment, as well as the previous embodiments, reference is made to fig. 4-1 through 4-4, wherein:

in fig. 4-1, a first current limiting unit is packaged with a first LED luminary; in fig. 4-2, it is shown that the current limiting unit may be packaged with the second LED luminary. In combination with the foregoing, it can be understood that, for a group of n LED luminaires in parallel, the current limiting unit may be provided together with any one of the LED luminaires;

in fig. 4-3, the current limiting unit can be packaged separately from the nearby LED luminary; in fig. 4-4, as in fig. 4-2, it is shown that the current limiting unit may be provided with any of the n parallel LED luminaries and packaged separately. It can be appreciated that when placed together and packaged independently of each other, the current limiting unit and the LED luminary correspond to: in the same general area, separate from each other, the LED luminous bodies are in external relation relative to the current limiting unit.

In another embodiment, in conjunction with fig. 4-3 and 4-4, for the stand-alone package:

the wires of the current limiting unit to the first LED luminary are connected to a single one of the brackets and further to the corresponding electrical connection wires, whereby the LED luminary is external with respect to the point control IC.

In another embodiment, the LED chip in any one of the LED luminaries is an LED chip used as a pixel to emit light.

Most typically, the strip-shaped lamp may be a point-controlled LED lamp. The point control LED lamp is particularly suitable for matching with a point control IC (integrated circuit) which is a current limiting unit and integrates point control capability. Typically, the dot control IC may also have the characteristics of a constant current IC. It should be noted that, because the point-control LED lamp usually needs an additional signal line in addition to two power supply lines of zero live line or positive and negative direct current. Although it is possible to transmit signals over the power supply line using two power supply lines and power carrier technology, the present invention prioritizes the manner of the additional signal lines. In addition, if the LED luminary itself is composed of three RGB LED bead chips, for this embodiment, the present invention can also be implemented as a segment-controlled LED lamp.

In another embodiment, the invention also discloses a module of the four-wire LED lamp.

As shown in fig. 5-1 through 5-3, wherein,

FIG. 5-1 schematically shows: for a four-wire LED module, from left to right, there are the first to n-th LED luminaries, the total n LED luminaries and their corresponding point control ICs are in one group, and the adjacent two groups are still in a disconnected state at the second electrical connection line, wherein fig. 5-1 clearly shows the disconnection gap at the disconnected position to disconnect the second electrical connection line. It can be seen that fig. 5-1 also illustrates that the current limiting unit is integrally packaged with the LED luminary. It can be understood that the utility model discloses be not limited to current limiting unit and the integrative encapsulation of LED luminous element, and LED luminous element can include ordinary LED chip.

In connection with fig. 4-1 and 4-2, it should be noted that, for the embodiment illustrated in fig. 4-1, 4-2, 5-1 and 5-2, if the current limiting unit is a current limiting IC, a disconnection gap at the disconnection point is very necessary, which can prevent the related IC from being damaged due to an improper short circuit; if the current limiting unit uses a resistor, the disconnection gap at the disconnection is not necessary.

FIG. 5-2 illustrates: in one group, it is not necessary that the click control IC be disposed with the first LED emitter.

Fig. 5-3 illustrate the four-wire LED module at other viewing angles.

Further, as compared to fig. 3-1, 3-2, and 3-3, fig. 5-1 through 5-3 also illustrate the blade cutting and uncut regions: the first electrode lead is the first electric connecting wire, the second electrode lead is the second electric connecting wire, and the third electrode lead is the third electric connecting wire.

In another embodiment, it is more important to note that:

for a four-wire LED module, the LED luminary with the click-controlled IC (e.g., the first leftmost LED luminary shown in fig. 5-1) includes the click-controlled LED chip. The rest second to nth LED luminous bodies can be only common LED chips. Since the point control IC is actually a specific implementation manner of the current limiting unit, and is still in a series relationship with the n parallel LED luminaries, taking the first LED luminary as an example, the point control IC controls the point control LED chip in the first LED luminary, so that the point control capability of all the n parallel LED luminaries can be realized.

In another embodiment, the wires of the pointing IC to the first LED luminary are connected to a single one of the brackets and to the corresponding electrical connection wires, so that the LED luminary is external with respect to the pointing IC.

Referring to fig. 6-1, in another embodiment, a six-wire LED lamp module is further disclosed, wherein, for the six-wire LED lamp module, the six wires thereof comprise: the LED lamp bead chip comprises a positive wire, a negative wire and a signal wire DIN for direct current power supply, and R, G, B three wires which are respectively connected with R, G, B of the LED lamp bead chip. Therefore, the segment control of the RGB is realized through six lines, and the three RGB lamp bead chips can be controlled in a targeted manner. As shown in fig. 6-1, the current limiting unit may include two terminals, and the two terminals are connected to the signal line DIN with a disconnection gap therebetween; each current limiting unit and a plurality of LED luminous bodies can form a group of units, and R, G, B three wires have wire breaking gaps between every two adjacent groups of units. It will be appreciated that the current limiting unit may also be replaced by a package comprising the current limiting unit, such as a segment control IC.

With further reference to fig. 6-2, in another embodiment, the current limiting unit and R, G, B three LED lamp bead chips are further disclosed. Wherein the current limiting units obviously encapsulate the IC, and each current limiting unit involves connecting two terminals of the DIN line, including a DIN terminal used as the current limiting unit signal input and a DOUT terminal used as the output, so as to transmit the signal to the subsequent current limiting unit.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
