Description

Technical Field

[0001] The present disclosure relates to an LED lamp, and in particular to an LED eaves lamp. Background Art

[0002] An eaves lamp is a lighting fixture that can be installed at the eaves of a building. However, the eaves are exposed to rain, so eaves lamps are generally waterproofed, for example, by applying a large amount of glue, which increases the material and cost. In addition, the installation space at the eaves is limited, which also puts forward requirements for the heat dissipation of the eaves lamp. These complex working conditions put forward requirements for the structural design and life of the eaves lamp. In addition, the existing manufacturing method of eaves lamps also faces the following problems: when welding the wires, short circuits are prone to occur due to limited operating space.

[0003] In view of this, it is necessary to develop a new LED eaves lamp to overcome the above technical problems. Utility Model Content

[0004] In view of this, the present disclosure provides an LED eaves lamp, comprising:

[0005] A first conductor, a second conductor and a lamp body, wherein

[0006] The first conductor includes two first power lines and a second power line insulated from each other, the second conductor includes two third power lines and a fourth power line insulated from each other, the first power line and the third power line are the same long wire that has not been disconnected, and the second power line and the fourth power line are the same long wire that has not been disconnected;

[0007] The first conductor penetrates from one side of the lamp body;

[0008] The second conductor passes through another side surface of the lamp body;

[0009] The lamp body comprises a PCB board and LED lamp beads. The side of the PCB board facing away from the LED lamp beads is free from any circuit components.

[0010] Preferably,

[0011] The first conductor further includes a first signal line,

[0012] The second conductor also includes a second signal line,

[0013] The first signal line and the second signal line are two signal lines formed by cutting off a long conductive line.

[0014] Preferably,

[0015] The lamp body also includes a bottom plate for fixing the LED eaves lamp.

[0016] The plane where the bottom plate is located is perpendicular to the one side surface or the other side surface,

[0017] The bottom plate and the PCB board are respectively located on two sides of the plane where the first conductor and / or the second conductor are located.

[0018] Preferably,

[0019] The bottom plate and the LED lamp beads are also respectively located on two sides of the plane where the first conductor and / or the second conductor are located.

[0020] Preferably,

[0021] At the welding positions where the PCB board is welded to the first conductor and the second conductor, the welding positions are formed by stripping off the insulation layers of the first conductor and the second conductor in advance.

[0022] Preferably,

[0023] The PCB board has a side facing the welding position, and the PCB board has at least one protrusion.

[0024] Preferably,

[0025] A lens is provided on one side of the PCB board facing the LED lamp bead.

[0026] Preferably,

[0027] The outer diameter of the PCB board is smaller than the outer diameter of the bottom plate.

[0028] Preferably,

[0029] A positioning hole is provided at the outer edge of the PCB board to position the PCB board and the lens.

[0030] Preferably,

[0031] The thickness of the protrusion is equal to or substantially equal to the thickness of the stripped insulation layer of the conductor.

[0032] In addition, the present disclosure also discloses a method for manufacturing an LED eaves lamp, comprising the following steps:

[0033] For a long conductor having at least two power supply wires insulated from each other, the long conductor is used as a light strip, and the insulation layer of the conductor is pre-stripped to expose the power supply wires therein, so as to form a welding position;

[0034] At the welding position, a side of the PCB board in the LED eaves lamp body, which is free from any circuit components, is welded at the welding position.

[0035] In summary, the present disclosure has the following features:

[0036] The LED eaves lamp disclosed in the present disclosure has no circuit components on the back, and all necessary circuit components are encapsulated inside the LED lamp beads, which has better space utilization, is not easy to cause faults such as short circuits at the welding position, and is conducive to the installation and heat dissipation of the PCB board and the base plate, thereby realizing a better structural design of the LED eaves lamp. In addition, the manufacturing method of the LED eaves lamp disclosed in the present disclosure significantly reduces the problem of short circuits that are prone to occur during welding, and does not require a long conductor to be cut or sheared as a whole to increase the process. In addition, the manufacturing method of the LED eaves lamp disclosed in the present disclosure also solves the problem of the inconvenience of directly connecting the wire to the lamp body caused by the thicker and thicker wire. In addition, since there are no circuit components on the side of the PCB board facing away from the lamp beads, after the PCB board is welded, the amount of glue required for dispensing at the welding position is also significantly reduced for the purpose of waterproofing. It is further to be pointed out that the protrusion of the PCB board not only facilitates the welding operation at the welding position, but also the thickness of the protrusion can be adjusted as needed. For example, when the thickness is adjusted to be equal to or approximately equal to the thickness of the stripped insulating layer of the conductor, the side of the PCB board facing away from the lamp bead after welding just fits with the plane of the first conductor and the second conductor, so as to avoid the situation in which the PCB board is lifted up by a part of the insulating layer that is not stripped off and causes a cold solder joint when welding the PCB board.

[0048] In one embodiment, the present disclosure provides an LED eaves lamp, comprising:

[0049] A first conductor, a second conductor and a lamp body, wherein

[0050] The first conductor includes two first power lines and a second power line insulated from each other, the second conductor includes two third power lines and a fourth power line insulated from each other, the first power line and the third power line are the same long wire that has not been disconnected, and the second power line and the fourth power line are the same long wire that has not been disconnected;

[0051] The first conductor penetrates from one side of the lamp body;

[0052] The second conductor passes through another side surface of the lamp body;

[0053] The lamp body comprises a PCB board and LED lamp beads. The side of the PCB board facing away from the LED lamp beads is free from any circuit components.

[0054] In another embodiment,

[0055] The first conductor further includes a first signal line,

[0056] The second conductor also includes a second signal line,

[0057] The first signal line and the second signal line are two signal lines formed by cutting off a long conductive line.

[0058] In another embodiment,

[0059] The lamp body also includes a bottom plate for fixing the LED eaves lamp.

[0060] The plane where the bottom plate is located is perpendicular to the one side surface or the other side surface,

[0061] The bottom plate and the PCB board are respectively located on two sides of the plane where the first conductor and / or the second conductor are located.

[0062] In another embodiment,

[0063] The bottom plate and the LED lamp beads are also respectively located on two sides of the plane where the first conductor and / or the second conductor are located.

[0064] In another embodiment,

[0065] At the welding positions where the PCB board is welded to the first conductor and the second conductor, the welding positions are formed by stripping off the insulation layers of the first conductor and the second conductor in advance.

[0066] In another embodiment,

[0067] The PCB board has a side facing the welding position, and the PCB board has at least one protrusion.

[0068] In another embodiment,

[0069] The thickness of the protrusion is equal to or approximately equal to the thickness of the stripped insulating layer of the conductor, so that the side of the PCB board facing away from the lamp bead after welding is exactly in contact with the plane of the first conductor and the second conductor.

[0070] In another embodiment,

[0071] A lens is provided on one side of the PCB board facing the LED lamp bead.

[0072] In another embodiment,

[0073] The outer diameter of the PCB board is smaller than the outer diameter of the bottom plate.

[0074] In another embodiment,

[0075] A positioning hole is provided at the outer edge of the PCB board to position the PCB board and the lens.

[0076] In another embodiment, the present disclosure also discloses a method for manufacturing an LED eaves lamp, comprising the following steps:

[0077] For a long conductor having at least two power supply wires insulated from each other, the long conductor is used as a light strip, and the insulation layer of the conductor is pre-stripped to expose the power supply wires therein, so as to form a welding position;

[0078] At the welding position, a side of the PCB board in the LED eaves lamp body, which is free from any circuit components, is welded at the welding position.

[0079] In another embodiment, for the manufacturing method,

[0080] The lens can be arranged in a suitable process in the form of upper and lower covers.

[0081] In another embodiment,

[0082] In the manufacturing method, the protective structure can be formed by direct injection molding after the lens is installed.

[0083] See also Figure 1 to Figure 2 , which illustrates the LED eaves lamp at different production stages on a long conductor, wherein:

[0084] Figure 1 Indicates the side of the PCB board facing away from the lamp beads and the welding position, where:

[0085] As mentioned above, the side of the PCB facing away from the LED lamp beads does not need to be equipped with any circuit components;

[0086] Figure 1 It also indicates that after the glue dispensing process, the side of the PCB board facing away from the lamp beads and the welding position are still covered with glue.

[0087] Combination Figure 1 , Figure 2 , can find that

[0088] The main body of the base plate has two ears extending from the main body of the base plate in the direction of the straight line passing through the centroid thereof, and a mounting hole is provided at the center of each ear, so as to fix and install the LED eaves lamp.

[0089] also,

[0090] The first straight line connecting the two mounting holes and the second straight line connecting the two positioning holes are located in the same plane perpendicular to the PCB board and the bottom plate.

[0091] Furthermore, compared with the two positioning holes, the two mounting holes are located further outside the plane where the PCB board is located.

[0092] In this way, not only the alignment of the PCB board and the lens is convenient, but also the fixation and installation of the LED eaves lamp is convenient, and there will be no obvious stress to affect the PCB board and the lens.

[0093] Exemplarily, the main body of the bottom plate may be circular, or may be a rounded rectangle, a racetrack, or other symmetrical shapes.

[0094] In another embodiment, in combination Figures 1 to 6 , can find that

[0095] The light strip includes a plurality of light bodies.

[0096] Each lamp body and the first conductor and the second conductor on both sides thereof constitute an LED unit on the light strip.

[0097] In another embodiment,

[0098] When the first conductor and the second conductor have only two insulated wires, one of the wires is used as the live wire or as a DC positive power supply, and the other wire is used as the neutral wire or as a DC negative power supply, and the two insulated wires are further used to transmit signals to control the working state of the lamp bead.

[0099] See also Figure 1 , Figure 2 , in another embodiment,

[0100] The PCB board has a side facing the welding position, and the PCB board has at least one protrusion, in particular, has two protrusions.

[0101] The two protrusions are respectively used for welding on two opposite sides.

[0102] As pointed out above, the protrusion of the PCB board not only facilitates the welding operation at the welding position, but also the thickness of the protrusion can be adjusted as needed. For example, when the thickness is adjusted to be equal to or approximately equal to the thickness of the stripped insulating layer of the conductor, the side of the PCB board facing away from the lamp bead after welding just fits with the plane of the first conductor and the second conductor, so as to avoid the situation where the PCB board is lifted up by a part of the insulating layer that is not stripped off and causes a cold solder joint when the PCB board is welded.

[0103] It can also be seen from this that in the LED eaves lamp disclosed in the present invention, the maximum outer diameter of the PCB board is larger than the maximum outer diameter of the area where the insulation layer is stripped at the welding position, so that a part of the unstripped insulation layer is still covered underneath the PCB board to protect the welding position.

[0104] In another embodiment, see Figures 1 to 6 ,

[0105] The first conductor includes three wires which are insulated from each other and located in the same plane;

[0106] The second conductor includes three wires which are insulated from each other and located in the same plane;

[0107] Among them, for the first conductor and the second conductor, two conductors are used for power supply lines, and the third conductor is used for signal lines. When the third conductor is used as a signal line, it can be disconnected or not:

[0108] When not disconnected, the signal line acts as a bus and transmits signals to the DIN in each LED unit on the light strip to control the operation of the lamp beads. Regardless of whether any lamp bead works normally or not, it does not affect the signal line transmitting signals to the lamp beads in other LED units. At this time, all LED units are in parallel relationship;

[0109] When disconnected, the signal line transmits a signal to the DIN in the first LED unit on the light strip to control the operation of its lamp beads, and outputs a signal from the DOUT in the first LED unit to other LED units at the subsequent stage. However, if one or some of the lamp beads in the middle do not work properly, it is highly likely that the signal line will not be able to successfully transmit signals to the lamp beads in other LED units at the subsequent stage.

[0110] For example,

[0111] When there are three wires, the first wire is used as the live wire or the power supply wire for the DC positive pole, the second wire is used as the neutral wire or the power supply wire for the DC negative pole, and the third wire is used to transmit signals to control the working state of the LED lamp beads. Figure 2As shown, if it is necessary to distinguish the wires connected to the positive pole or the negative pole, a dot can be made on the outer surface of one of the wires as a marking point to indicate that this wire is dedicated to connecting the positive pole or the negative pole.

[0112] In another embodiment,

[0113] The first conductor and the second conductor are both in a strip structure, and the width of the strip structure of the first conductor and the second conductor is slightly smaller than the outer diameter of the area covered by the glue at the welding position and the side of the PCB board facing away from the lamp bead.

[0114] Therefore, this fully demonstrates that the solution disclosed in the present disclosure significantly reduces the amount of glue used, which is also due to the fact that no circuit components are set on the side of the PCB board facing away from the lamp beads.

[0115] It should be noted that in the scenario of 110V-230V AC power supply, each lamp bead itself includes dozens of LED chips connected in series or in series-parallel mixed to withstand 110V or 230V AC voltage. Even if the LED eaves lamp disclosed in the present invention includes 3 lamp beads, cut off any one of the lamp beads, and connect it to 110V or 230V AC while preserving the electrode wires on both sides of the lamp bead. As long as the lamp bead itself does not have any faults, a loop can be formed to make it emit light. In contrast, the lamp beads connected in series obviously cannot do this, because the multiple lamp beads connected in series can only work as a whole under 110V or 230V voltage. If one of the lamp beads is directly cut and connected to 110V and 230V voltage, the lamp bead is likely to burn out. It can be understood that the present disclosure is not limited to voltages such as 110V and 230V. It can be other power supply voltage standards or a wider voltage range.

[0116] Therefore, in the case of parallel connection, the LED eaves lamp can freely cut each lamp bead, and after cutting, each lamp bead can meet the supply voltage requirement when connected to the power supply. In addition, in the case of a lamp bead failure, the faulty lamp bead can be freely cut off and the original front and rear sections can be connected. In the case of a small length loss, it continues to work under the same supply voltage and can maintain the consistency of the visual effect of the lighting, that is, the brightness.

[0117] In one embodiment, the lamp beads are of SMD type, which is more conducive to improving manufacturing efficiency and ensuring product performance.

[0118] In one embodiment, the lamp beads are high voltage type, which is conducive to the production of high voltage parallel products.

[0119] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
