Description

Technical Field

[0001] The utility model belongs to the field of LED lamps and relates to a high-voltage leather wire lamp string. Background Art

[0002] Currently, the leather-wire light strings on the market are all low-voltage products, 5-24V, low voltage, and high current under the same power consumption, which places high demands on conductive wires.

[0003] In low-voltage circuits, there are few LED light-emitting components in series, but many circuits are connected in parallel. If current-limiting components are added to each circuit, the number will be large, and current-limiting components in flexible wires are more difficult to weld and more easily damaged than LED light-emitting components. Therefore, for cost considerations, existing products do not use current-limiting components in LED light-emitting circuits, and the working state of LED light-emitting components is uncertain and unstable, which can easily cause component damage. Utility Model Content

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a high-voltage leather wire light string, including a wrapping layer, and a connecting wire module arranged on the wrapping layer;

[0005] The connecting wire module includes a first power wire and a second power wire arranged on both sides of the inner side of the wrapping layer, and a circuit control board arranged between the first power wire and the second power wire;

[0006] The end of the circuit control board includes a first terminal and a second terminal; the first terminal is electrically linked to the first power supply wire, and the first terminal is electrically connected to the first power supply wire;

[0007] The circuit control board comprises a plurality of light-emitting element series connection units composed of 9 light-emitting elements in series, with an operating voltage of 110V or 220V;

[0008] The light-emitting element series unit includes a first light-emitting element, a second light-emitting element ... and a ninth light-emitting element;

[0009] The second light emitting element ... and the ninth light emitting element have the same structure;

[0010] The first light-emitting element adopts an LED with a specification of 3020, and the first light-emitting element has a built-in constant current element;

[0011] The second light emitting element... and the ninth light emitting element adopt LED with specification model 3020.

[0012] Furthermore: the color temperature of the first light-emitting element, the second light-emitting element... and the ninth light-emitting element is 2700K-6500K.

[0013] Furthermore: it also includes a loop connection line formed by the circuit control board, and the specification of the wiring harness formed by the loop connection line, the first power supply wire and the second power supply wire is 4*AWG24.

[0014] Furthermore, the intervals between the first light-emitting element, the second light-emitting element, ... and the ninth light-emitting element are set to be 50-500 mm.

[0015] Furthermore, the first light-emitting element, the second light-emitting element ... and the ninth light-emitting element are arranged by alternating cathodes and anodes.

[0016] The utility model provides a high-voltage leather-wire light string, which has the following advantages: the number of LED light-emitting elements in the circuit designed by the application is increased compared with low-voltage products, and the number of parallel connections is reduced. In addition, since the welding of independent current-limiting elements is difficult and has an impact on the appearance of the product, the component is integrated into the first LED light-emitting element of the circuit, reducing one component position, without affecting the appearance of the product, making the entire circuit work stably and reliably, and ensuring the life of the product.

[0017] Each LED light-emitting circuit has a constant current element for current limiting driving to ensure the stability and reliability of the product;

[0018] The high-voltage leather-wire light string of the present application has a working current reduced by 4 (relative to 24V products) - 20 (relative to 5V products) times at the same power, and the connection length can be increased by 4-20 times under the same wire conditions.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0028] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0030] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0031] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
