This application claims priorities from Chinese Patent Application Nos. 2021108941893, filed Aug. 4, 2021, and from 2021111046598 filed Sep. 18, 2021, the content of which are incorporated herein in the entirety by reference.
The present disclosure relates to the technical field of led light structures, in particular to an LED strip light and an expansion structure thereof.
An LED, namely a light emitting diode, is a light emitting device that converts electric energy into light energy, and has been widely used for lighting urban landscapes due to its advantages of energy saving, long service life, various light colors, and the like.
The voltage of an existing cascaded point-controlled LED light is mostly 5V-12V and mostly in a full parallel connection structure. However, at the current voltage of 5V-12V, if the number of carried luminous bodies is large, the voltage drop caused by wires and the luminous bodies is large, and in addition, the current required by the parallel connection structure is larger, so that the wires are thicker, a power supply is larger, and the cost is increased.
If the parallel connection structure is changed into a series connection structure, although a high-voltage light can be formed, LED chips or LED luminous bodies are arranged at intervals, and in a process of manufacturing the LED light, the arrangement errors of positive pins and negative pins are easily caused, so that the manufacturing efficiency is low or faults occur in the testing/using process.
On that account, the present disclosure provides an LED strip light, including:

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to
Thus, the following detailed description of the embodiments of the present disclosure, as presented in the figures, is not intended to limit the scope of the present disclosure, as claimed, but is merely representative of selected embodiments of the present disclosure. All other embodiments, which can be obtained by a person skilled in the art without creative efforts based on the embodiments of the present disclosure, are within the scope of protection of the present disclosure.
It should be noted that: like reference signs 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 disclosure, it should be noted that, if the terms “upper”, “lower”, “inner”, “outer”, “parallel”, “vertical” and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings or orientations or positional relationships that are usually placed when the product of the present disclosure is used, it is only for the convenience of describing the disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus, it should not be construed as limiting the present disclosure.
Furthermore, when the terms “first”, “second”, etc. appear, they are only used to distinguish one description 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 disclosure may be combined with each other without conflict.
In an embodiment, the present disclosure provides an LED strip light, including:
With regard to the embodiment mentioned above, when in a series connection relationship, since signal lines are always in a roughly aligned spatial location relationship, it is easy to connect the signal lines to acquire data signals of LEDs to correctly display visual contents no matter how many LED luminous bodies extend along the second direction. When the first LED luminous body and the second LED luminous body are selected to be in a series connection relationship, the second type of pins and the third type of pins which are in a roughly aligned spatial location relationship are successively connected in series along almost the same straight line to form a correct series connection relationship while being arranged in a staggered manner; and similarly, in the above solution, parallel connection also can be considered, and thus, the same type of pins are successively connected in parallel along almost the same straight line to form a correct parallel connection relationship.
Specifically, for example, when positive and negative electrodes supply power, the positions of positive electrode pins and negative electrode pins of two adjacent LED luminous bodies are opposite, so that when the luminous bodies are connected in series, normal surface mounting is facilitated, and series connection of the luminous bodies with signal inputs and outputs is facilitated.
It can be appreciated that the second direction being perpendicular to the first direction is only a preferred case, which is advantageous for the strip light to extend in a direction perpendicular to the first direction. However, if the second direction is parallel to the first direction, the extending direction of the strip light may be parallel to the first direction as long as the strip light can still be connected to the relevant signal line and the power supply wire. Further, in connection with the following cascade/expansion embodiments, it can be understood that the second direction is perpendicular to or parallel to the first direction, and only when the cascade/expansion is changed, the strip lights are still parallel to each other, and the difference only lies in that: the strip lights are parallel to one another along a direction parallel to the first direction, or the strip lights are parallel to one another along a direction perpendicular to the first direction. Thus, in an expansion manner, the second direction may be at any angle to the first direction, the second direction and the first direction are not limited to be perpendicular to each other at a corresponding angle of 90 degrees or be parallel to each other at a corresponding angle of 0 degree.

An embodiment of the present disclosure further provides a curtain structure, the curtain structure includes the plurality of high-voltage point-controlled cascaded LED strip lights, and the plurality of high-voltage point-controlled cascaded LED strip lights are connected to each other to form the curtain structure. Because the curtain structure includes the high-voltage point-controlled cascaded LED strip lights, the curtain structure also has the beneficial effects of low current, low cost, and a large number of carried lights.
The curtain structure 10 includes a plurality of high-voltage point-controlled cascaded LED strip lights 100, and the plurality of high-voltage point-controlled cascaded LED strip lights 100 are connected to one another to form the curtain structure 10 in the shape of a curtain.
The high-voltage point-controlled cascaded LED strip light 100 includes a plurality of luminous bodies 110, the plurality of luminous bodies 110 are connected to one another in series, and thus, the technical problem that an existing parallel connection type cascaded point-controlled LED light is high in current and high in cost can be effectively solved. The luminous body 110 is provided with a positive electrode pin 125 and a negative electrode pin 126, meanwhile, the positions of the positive electrode pins 125 and the negative electrode pins 126 of the two adjacent luminous bodies 110 are opposite, thus, when connected in series, the plurality of luminous bodies 110 may be subjected to normal surface mounting, and series connection of the luminous bodies 110 with signal inputs and outputs is facilitated.
When common LED luminous bodies 110 are connected in series on two wires, different groups of LEDs need to be placed at an angle of 180 degrees (namely, a first group of LEDs are subjected to normal surface mounting, a second group of LEDs are subjected to surface mounting at an angle of 180 degrees, and a third group of LEDs are also subjected to normal surface mounting), the production difficulty is high, moreover, if the luminous bodies 110 with signal inputs and outputs are subjected to surface mounting at an angle of 180 degrees, the positions of signal inputs and outputs are opposite, and then abnormality of the strip light is caused. In the high-voltage point-controlled cascaded LED strip light 100, positions of the positive electrode pins 125 and the negative electrode pins 126 of the two adjacent luminous bodies 110 are opposite, therefore, when connected in series, the plurality of luminous bodies 110 may be subjected to normal surface mounting, and series connection of the luminous bodies 110 with signal inputs and outputs is facilitated.
It should be noted that, the positions of the positive electrode pins 125 and the negative electrode pins 126 of the two adjacent luminous bodies 110 are opposite, namely, in the two adjacent luminous bodies 110, the negative electrode pin 126 of the other luminous body 110 is arranged at the position of the positive electrode pin 125 in one luminous body 110, the positive electrode pin 125 of the other luminous body 110 is arranged at the position of the negative electrode pin 126 of one luminous body 110, in other words, the luminous bodies 110 in the high-voltage point-controlled cascaded LED strip light 100 have two structures, the luminous bodies 110 of the two structures are a first luminous body 111 and a second luminous body 112 respectively, the structure of the first luminous body 111 is roughly the same as that of the second luminous body 112, and the difference lies in that the positive and negative electrode pins 126 of the two luminous bodies 110 are reversed in position (as shown in
The structure of the high-voltage point-controlled cascaded LED strip light 100 provided in the embodiment is further described below:
Further, the luminous body 110 further includes a second substrate 119 and a third substrate 121, and the second substrate 119 and the third substrate 121 are both connected to the rack body 113. An end of the second substrate 119 and an end of the third substrate 121 extend out of the rack body 113 to form positive and negative electrode pins 125, 126 of the luminous body 110. Specifically, in the first luminous body 111, an end of the second substrate 119 extends out of the rack body 113 to form a positive electrode pin 125, and an end of the third substrate 121 extends out of the rack body 113 to form a negative electrode pin 126; and in the second luminous body 112, an end of the second substrate 119 extends out of the rack body 113 to form a negative electrode pin 126, and an end of the third substrate 121 extends out of the rack body 113 to form a positive electrode pin 125.
Specifically, the rack body 113 is square, and the rack body 113 is provided with a first edge 114, a second edge 115, a third edge 116 and a fourth edge 117 which are connected end to end. An end of the first substrate 118 extends out of the rack body 113 from the first edge 114, two ends of the second substrate extend out of the rack body 113 from the second edge 115 and the fourth edge 117 respectively, and an end of the third substrate 121 extends out of the rack body 113 from the third edge 116.
Further, the first substrate 118, the second substrate 119 and the third substrate 121 are spaced from one another, a luminous chip of the luminous body 110 is arranged on the second substrate 119, and thus, exchange of a positive electrode and a negative electrode in the luminous body 110 is facilitated to form the two luminous bodies 110 including the first luminous body 111 and the second luminous body 112 which have the opposite positions of the positive electrodes and the negative electrodes.
With reference to

After connection, a structure shown in
Besides, in order to guarantee normal operation of the luminous bodies 110, signal outputs and signal inputs cannot communicate with each other directly, and thus, the signal lines 133 need to be shorn off. In order to facilitate line shearing, the weld leg formed by the first substrate 118 includes a first weld leg portion 122 and a second weld leg portion 123, the first weld leg portion 122 and the second weld leg portion 123 respectively extend out of the rack body 113, the first weld leg portion 122 and the second weld leg portion 123 are spaced from each other, and thus, a trimming opening 124 is formed between the first weld leg portion 122 and the second weld leg portion 123. Specifically, during production, different parts of the complete signal line 133 are separately welded to the first weld leg portion 122 and the second weld leg portion 123, then the portion, between the first weld leg portion 122 and the second weld leg portion 123, of the signal line 133 is shorn off, thus, the signal line 133 is connected to one of the first weld leg portion 122 and the second weld leg portion 123 for signal input, and the signal line 133 is connected to the other one of the first weld leg portion 122 and the second weld leg portion 123 for signal output.
