Description

Line lamp connecting method and line lamp connecting circuit

Technical Field

The present invention relates to a line lamp, and more particularly, to a line lamp connecting method and a line lamp connecting circuit.

Background

The lamps (String light) are formed by welding a plurality of light sources directly on the wires at intervals to form a linear lighting device, thereby eliminating the conventional lamp holder configuration. For small light sources, such as bulbs and light emitting diodes, a frequently applied configuration is provided. The light (String light) retains the original property of being able to wind the wire, so that the light (String light) can be easily configured in any form to be suitable for special lighting requirements or decoration.

The traditional mode of welding the light source is that after an insulating layer of an electric wire is directly stripped, an electrode of the light source is welded on an exposed copper core, and then insulation treatment is carried out on a welding point. The light source will obviously protrude from the wire and has obvious light emitting directivity. In fact, when the line lamp is pulled for wiring, the protruding light source may be caught by foreign matter, resulting in the solder joint being dropped. Although the wire itself allows for substantial bending, the solder of the solder joint portion generally lacks bendability. Therefore, when the wire is pulled or bent, the stress point of the wire lamp is just located on the solder, which is easy to generate improper stress on the solder and can cause the welding point to fall off.

In addition, the electrical connection lines of the light sources are usually all connected in parallel or all connected in series. All parallel connection represents that the output voltage of the power supply must be accurately matched with the requirement of the light source to drive the light source and avoid the over-current burning of the light source. The series connection mode can determine the series connection quantity according to the output voltage of the power supply, so that each light source obtains the required voltage difference; however, the disadvantage of the series connection is that the number of series connections cannot be changed arbitrarily (limited by the applicable power output voltage), and the damage of a single light source can also cause the whole series line lamp to be disconnected and unusable.

Detailed Description

Referring to fig. 1, 2 and 3, a linear light 100 according to a first embodiment of the present invention includes one or more light emitting elements 130, a first conductive line 110, a second conductive line 120, solder 140 and a transparent glue 150.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, although only one light emitting element 130 is shown, in practice, two or more light emitting elements 130 may be continuously disposed between the first conductive line 110 and the second conductive line 120 in parallel. Each light emitting device 130 includes a substrate 131 and a light source 132. The substrate 131 has a carrying portion 133 and two soldering portions 134. The carrying portion 133 is located between the two welding portions 134, and the light source 132 is disposed on the carrying portion 133.

Each of the soldering portions 134 is at least provided with a conductive material 135 on the surface layer and is electrically connected to the light source 132. The conductive material 135 may be formed by plating a metal layer on the soldering portion 134 to form the conductive material 135, or by directly forming the soldering portion 134 from metal, such that the substrate 131 is formed by splicing the insulating portion (the supporting portion 133) and the conductive portion (the soldering portion 134).

As shown in fig. 4, the light source 132 further includes a light emitting element 136 and a transparent package 137. The light emitting element 136 is disposed on the carrier portion 133 of the substrate 131, and the transparent package 137 encapsulates the light emitting element 136.

One embodiment of the light emitting device 130 is a surface mount light emitting diode (SMT LED), the light emitting device 136 is a light emitting diode chip, and the substrate 131 is a sapphire substrate 131; the transparent package 137 may be a cured liquid adhesive, which is cured after being dispensed on the led chip to form the transparent package 137, and an outer convex curved surface is formed on the upper surface of the transparent package 137 to improve the light emitting range and the light emitting efficiency. The liquid glue can be prepared by doping sealing resin with fluorescent powder, and the liquidity of the liquid glue is adjusted by the proportion of the fluorescent powder so as to change the curvature of the convex curved surface.

As shown in fig. 1, fig. 2 and fig. 4, the first conductive line 110 has a first conductive core 112 and a first insulating layer 114. The first insulating layer 114 covers the first conductive core 112 and partially exposes the first conductive core 112 to form at least one first bonding segment 116. The number of first soldering segments 116 is the number corresponding to the number of light emitting assemblies 130.

As shown in fig. 1, fig. 2 and fig. 4, the second conductive line 120 has a second conductive core 122 and a second insulating layer 124. The second insulating layer 124 covers the second conductive core 122 and partially exposes the second conductive core 122 to form at least one second bonding segment 126. The number of second soldering segments 126 corresponds to the number of light emitting assemblies 130. And the first welding section 116 and the second welding section 126 are arranged in pairs.

As shown in fig. 2 and 4, the first soldering segment 116 and the second soldering segment 126 are respectively disposed on the two soldering portions 134 of the substrate 131, and the light source 132 is located between the first soldering segment 116 and the second soldering segment 126, so that the first soldering segment 116 and the second soldering segment 126 clamp the light source 132.

As shown in the drawings, the solder 140 is disposed on the two welding portions 134, at least partially covers the first welding portion 116 and the second welding portion 126, and the solder 140 welds the first welding portion 116 and the second welding portion 126 to the two welding portions 134. In order to ensure that the first bonding segment 116 and the second bonding segment 126 do not fall off, the solder 140 may further extend to cover the lateral edges and the back surface of the substrate 131, and the lateral edges and the back surface are also provided with the conductive material 135 at least on the surface layer.

As shown in fig. 1 and fig. 2, the transparent encapsulant 150 encapsulates the light emitting element 130, the first bonding segment 116 and the second bonding segment 126, and further extends to partially encapsulate the first insulating layer 114 and the second insulating layer 124. The transparent encapsulant 150 has a maximum cross-sectional area corresponding to the light source 132, and the cross-sectional area is tapered as the transparent encapsulant 150 extends toward the first insulating layer 114 and the second insulating layer 124. That is to say, the transparent encapsulant 150 not only encapsulates the light emitting element 130, the first soldering segment 116 and the second soldering segment 126, but also encapsulates the portions of the first insulating layer 114 and the second insulating layer 124, which are respectively adjacent to the first soldering segment 116 and the second soldering segment 126, by the transparent encapsulant 150.

The transparent Adhesive 150 may be a liquid Adhesive such as an ultraviolet light curing Adhesive (UV Cure Adhesive) that can be cured quickly. After the light source 132 is dispensed by the dispensing tool, the liquid glue overflows to the adjacent first insulating layer 114 and second insulating layer 124, and is then rapidly irradiated by the ultraviolet light to be cured and shaped.

As shown in fig. 4, the transparent encapsulant 150 extends to cover the first insulating layer 114 and the second insulating layer 124. The transparent encapsulant 150 is cured to maintain a certain rigidity, such that the hardness of the transparent encapsulant 150 is greater than the hardness of the first conductive lines 110 and the second conductive lines 120. Therefore, when the first conductive wires 110 and the second conductive wires 120 are bent due to the wiring requirement, the portions of the first conductive wires 110 and the second conductive wires 120 connected to the light emitting element 130 are not bent, thereby avoiding the problem that the first welding sections 116 and the second welding sections 126 are separated from the welding portion 134 due to the bending stress. In addition, the transparent colloid 150 can provide a light guide effect, so that the light source 132 which is originally only directional emits light, and the light is guided through the transparent colloid 150 to form a multi-directional light emitting effect.

As shown in fig. 5, on the other hand, when the first wire 110 and the second wire 120 are under tension, the first welding section 116 and the second welding section 126 are close to the light source 132 of the light emitting element 130 without lateral displacement relative to the welding portion 134. Therefore, the solder 140 between the first soldering section 116 and the soldering portion 134 and between the second soldering section 12 and the soldering portion 134 are not subjected to the transverse shear stress, so as to avoid the problem that the first soldering section 116 and the second soldering section 126 are subjected to the transverse shear stress and fall off from the soldering portion 134.

That is, the transparent encapsulant 150 extends and covers the lamp 100 to enhance the strength of the lamp 100 against bending stress, and the relative positions of the first soldering segment 116, the second soldering segment 126 and the light emitting element 130 enhance the strength of the lamp 100 against tensile stress.

Although the first conductive core 112 and the second conductive core 122 shown in fig. 1 to 5 are single metal wires (copper wires or other metal wires suitable as wires), the first conductive core 112 and the second conductive core 122 may be stranded wires. The first insulating layer 114 and the second insulating layer 124 are respectively independent insulating plastic layers in the first embodiment, but are not excluded as insulating varnish, that is, the first conducting wire 110 and the second conducting wire 120 may be enameled wires. Alternatively, the first insulating layer 114 and the second insulating layer 124 may be connected together to facilitate the construction and routing of the first conductive line 110 and the second conductive line 120.

Referring to fig. 6, a line lamp connecting circuit 2 according to a second embodiment of the present invention is shown, for configuring the light emitting device 130 according to the first embodiment as a long line lamp with both series connection and parallel connection.

As shown in fig. 6, the line lamp connecting circuit 2 of the second embodiment includes a first conductive line 110, a second conductive line 120, a third conductive line 160 and a plurality of light emitting elements 130.

As shown in fig. 6, the first conducting wire 110 is used for receiving a first potential V1 input, and the first potential V1 may be 6V dc; the third wire 160 is used for receiving a third potential V3, which may be a ground potential (GND). The second conductive line 120 serves as a node for connecting the light emitting elements 120 to each other.

The light emitting element 130 is substantially the same as the first embodiment, and the details thereof are not repeated. In the second embodiment, the welding portion 134 of each light emitting element 130 is further subdivided into a positive welding portion (+) and a negative welding portion (-) according to the polarity of the light source 132 (especially for the light emitting diode), the carrying portion 133 of the first embodiment is located between the positive welding portion (+) and the negative welding portion (-), and the light source 132 is disposed on the carrying portion 133 and electrically connected to the positive welding portion (+) and the negative welding portion (-).

As shown in fig. 6, some of the light emitting elements 130 are connected to the first conductive wire 110 at their positive electrode bonding portions (+) and connected to the second conductive wire 120 at their negative electrode bonding portions (-) and other light emitting elements 130 are connected to the second conductive wire 120 at their positive electrode bonding portions (+) and connected to the third conductive wire 160 at their negative electrode bonding portions (-).

Therefore, the light emitting elements 130 can be divided into two groups. The first group of light emitting devices 130 are connected in parallel, and the first conductive line 110 and the second conductive line 120 are two parallel connection terminals, the second group of light emitting devices 130 are connected in parallel, and the second conductive line 120 and the third conductive line 160 are two parallel connection terminals. The first group of light emitting elements 130 and the second group of light emitting elements 130 are connected in series by the second wires 120 as connection terminals.

Referring to fig. 6, the line lamp connecting circuit 2 of the second embodiment further includes a current limiting resistor 180 connected in series between the first conductive line 110 and the first potential V1 for limiting the magnitude of the passing current. The current limiting resistor 180 limits the current outputted from the first potential V1 to the first wire 110, thereby avoiding the over-current through the light emitting element 130 from causing burnout.

In the second embodiment, the first conductive lines 110, the second conductive lines 120 and the third conductive lines 160 are substantially disposed in parallel, so that the three

conductive lines

110, 120 and 160 can be combined together through the insulating layer as the first conductive lines 110, the second conductive lines 120 and the third conductive lines 160 in the first embodiment, and are separated only at the portion where the light emitting device 130 is disposed. Therefore, the wire can become a long wire lamp, which is beneficial to installation and wire laying.

Referring to fig. 7 and 8, a line lamp connecting circuit 3 provided for a third embodiment includes a first conductive line 110, a second conductive line 120, a third conductive line 160 and a plurality of light emitting elements 130, wherein the line lamp connecting circuit 3 of the third embodiment is further provided with a third cut-off point C3, a second cut-off point C2 and a first cut-off point C1 to form a required current path.

The third cutting point C3, the second cutting point C2, and the first cutting point C1 sequentially cut the third conductive line 160, the second conductive line 120, and the first conductive line 110 at intervals according to the extending direction L, so that the line lamp connecting circuit 3 is divided into a plurality of sections according to the third cutting point C3, the second cutting point C2, and the first cutting point C1.

A plurality of light emitting elements 130 are provided, which are substantially the same as the light emitting elements 130 of the first embodiment or the second embodiment, each light emitting element 130 includes a substrate 131 and a light source 132, the substrate 131 has a supporting portion 133, a positive electrode welding portion (+) and a negative electrode welding portion (-), the supporting portion 133 is located between the positive electrode welding portion (+) and the negative electrode welding portion (-), and the light source 132 is disposed on the supporting portion 133 and electrically connected to the positive electrode welding portion (+) and the negative electrode welding portion (-).

As shown in fig. 8, the plurality of light emitting elements 130 are arranged in groups. The first group of light emitting elements 130 are connected to the first conductive line 110 by their positive electrode bonding portions (+) and connected to the second conductive line 120 by their negative electrode bonding portions (-) before the first cutting point C1 according to the extending direction L.

As shown in fig. 8, the second group of light emitting elements 130 is connected to the second conductive wire 120 by its positive electrode bonding portion (+) and connected to the third conductive wire 160 by its negative electrode bonding portion (-) between the third cutting point C3 and the second cutting point C2 according to the extending direction L.

As shown in fig. 8, the third group of light emitting elements 130 is connected to the second wire 120 by the negative electrode bonding portion (-) and connected to the third wire 160 by the positive electrode bonding portion (+) after the second cutting point C2 according to the extending direction L.

Meanwhile, the first group of light emitting elements 130 and the second group of light emitting elements 130 are connected in series by the second wires 120 as connection terminals.

The third group of light emitting devices 130 are connected in parallel, the second conductive line 120 and the third conductive line 160 are two connecting terminals connected in parallel, but the polarity is opposite to that of the second group, and the second conductive line 120 between the second group and the third group is disconnected by the second disconnection point C2, so that the third group of light emitting devices 130 are actually connected in series with the second group. Similarly, the fourth light emitting device 130 is connected in parallel, the first conductive line 110 and the second conductive line 120 are two connecting terminals connected in parallel, but the polarity is opposite to that of the first light emitting device, and the first conductive line 110 is disconnected by the first disconnection point C1 between the first light emitting device and the fourth light emitting device, so that the fourth light emitting device 130 is connected in series with the third light emitting device 130.

As shown in fig. 8, one end of the first conductive line 110 receives a first potential V1, which may be 110V/220V direct current. The other end of the first conductive line 110 is further connected to a boost line 170, and the boost voltage V4 of the boost line 170 can be set according to the voltage level of the first conductive line 110 and the total voltage required by the four groups of light emitting devices 130 to boost the voltage applied to the light emitting devices 130.

Similarly, in the third embodiment, the first conductive line 110, the second conductive line 120, the third conductive line 160 and the boost line 170 are substantially arranged in parallel, and can be a long line lamp, which is beneficial to installation of the paving line.

In this way, the light emitting element 130 can be connected in parallel between the first conductive line 110 and the second conductive line 120, and is normally driven by the potential difference between the first conductive line 110 and the second conductive line 120. The boost line 170 can set the boost potential V4 of the boost line 170 for the potential of the first conductive line 110 and the voltage required by the light emitting device 130 to emit light, thereby boosting the voltage applied to the light emitting device 130.

Similarly, in the fourth embodiment, the first conductive line 110, the second conductive line 120 and the boost line 170 are substantially arranged in parallel, and can be a long linear light, which is advantageous for installation of paving lines.

The current limiting resistor 180 limits the current outputted from the first potential V1 to the first wire 110, thereby avoiding the over-current through the light emitting element 130 from causing burnout. The current limiting resistor 180 may be disposed on the boost line 170 so as to be in a series path, which may also exert a current limiting effect.

The light emitting device 130a of the fifth embodiment further includes a control chip 138, and the control chip 138 is coupled to the substrate 131 for controlling the light source 132 to be turned on or off. The control chip 138 has a signal input point DI and a signal output point DO.

As shown in fig. 10 and 11, the first conductive line 110 is used for receiving a first potential V1, such as 5V dc. The second conductive line 120 receives a second potential V2, which may be a ground potential (GND). The third conductive line 160 has a signal input terminal DATA IN and a signal output terminal DATA OUT; the third wire 160 has a plurality of cut-off points C, wherein each light emitting device 130 is disposed IN each cut-off point C, and is connected to the third wire 160 at different sides of the cut-off point C by a signal input point DI and a signal output point DO, respectively, wherein the signal input point DI corresponds to the signal input terminal DATA IN of the third wire 160, and the signal output point DO corresponds to the signal output terminal DATA OUT of the third wire 160.

The third wire 160 receives the on/off control signal of the light source 132 from the signal input terminal DATA IN, controls the corresponding light source 132 after being transmitted to the control chip 138 from the signal input point DI, and transmits the control signal to the control chip 138 of the next light emitting device 130 from the signal output point DO. Finally, the control signal can be transmitted from the signal output terminal DATA OUT to another set of line lamp connecting circuits 5.

Referring to fig. 6, the line lamp connecting circuit 5 of the fifth embodiment further includes a current limiting resistor 180 connected in series between the first conductive line 110 and the first potential V1 for limiting the magnitude of the passing current. The current limiting resistor 180 limits the current outputted from the first potential V1 to the first wire 110, thereby avoiding the over-current through the light emitting element 130 from causing burnout.

Through the above embodiments of the present invention, the light emitting element 130 can be more stably disposed between the first conductive line 110 and the second conductive line 120, and provide a good illumination effect. In addition, the design of the line lamp connection circuit increases the diversity of the power supply method, and can match with the light sources 132 of various specifications, and ensure that each light source 135 can receive enough voltage input under the condition that a plurality of light sources 132 are configured simultaneously, without the problem that the voltage difference of each light source 132 is insufficient due to excessive light sources 135.
