Description

Technical Field

[0001] The utility model relates to the technical field of film and television lamps, in particular to a lamp board and an inflatable stick lamp. Background Art

[0002] With the rise of various short videos, the public's demand for filming has increased significantly. In order to obtain better shooting effects, in addition to the good performance of the camera used for shooting, the light conditions in the shooting scene are also very important. The inflatable stick light is an easy-to-carry film and television lighting fixture. When using it, just fill the inflatable stick light with gas. After use, the gas in the inflatable stick is emptied and curled up for storage. It takes up little space and is very suitable for carrying out shooting.

[0003] Inflatable stick lights generally have built-in light sources, and achieve the purpose of emitting light by installing a certain number of light-emitting elements on a circuit board. Since the light-emitting elements are arranged along the length of the light board, the corresponding wiring used to connect the light-emitting elements is also arranged along the length of the light board to connect different light-emitting elements in series.

[0004] In the related art, light-emitting elements such as LED lamp beads are generally hard structures with a certain length, width, and thickness rather than flexible elements. When users roll up the inflatable stick lamp to store it, the built-in lamp board will also be rolled up. Although the base material and cover layer of the lamp board are flexible, the copper foil wiring inside it is also very thin and has a certain flexibility. However, when the lamp board is rolled up, it is easy to generate stress concentration along the rolling direction and near the LED lamp beads or other electronic components, which can easily cause the wiring in this area to break or break. Especially when the inflatable stick lamp is rolled to a greater extent (i.e., more curling turns are used), the problem of stress concentration will be more obvious, which will reduce the reliability of the entire inflatable stick lamp and poor user experience. Utility Model Content

DETAILED DESCRIPTION

It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] See also Figures 1 to 3 The present embodiment provides a light board that can be installed on an inflatable stick lamp to realize the light emission of the inflatable stick lamp. The light board includes a flexible board body 1 and a plurality of light-emitting elements 2. The flexible board body 1 is the main structure of the light board. The flexible board body 1 is used to carry other electronic components installed on the light board. The flexible board body 1 is a circuit board. To adapt to the inflatable stick lamp, the light board can match the shape of the inflatable stick lamp. For example, when the inflatable stick lamp is in the shape of a long column, the light board is correspondingly in the shape of a long plate. When the inflatable stick lamp is in the shape of a ring, the light board is correspondingly in the shape of a ring plate.

[0049] In some embodiments, the flexible board 1 has a certain flexibility and can be rolled along its own length direction to cooperate with the inflatable stick light to be rolled synchronously when stored. The flexible board 1 can be a flexible circuit board, which can be a highly reliable flexible printed circuit board made of polyimide or polyester film as a substrate, so that it can be rolled.

[0050] In some embodiments, a plurality of light-emitting elements 2 are arranged on the flexible board 1 at intervals along the length direction of the flexible board 1, so that the light board is installed with a plurality of light-emitting elements 2 along its own length direction, and the light-emitting range of the light board is larger. The light-emitting element 2 includes a body 20 arranged on the flexible board 1 and a positive electrode pin 21 and a negative electrode pin 22 arranged at opposite ends of the body 20. The body 20 is the main structure of the light-emitting element 2, and a light-emitting chip can be arranged inside it for controlling light emission. The body 20 itself can be in a rectangular block shape, which is fixed on the flexible board 1. The positive electrode pin 21 and the negative electrode pin 22 arranged at opposite ends of the body 20 are connected to the light-emitting chip in the body 20 for current transmission.

[0051] In this embodiment, the light emitting element 2 may be an LED lamp bead, also referred to as a light emitting diode. The light emitting element 2 has a unidirectional conduction characteristic. When the light emitting element 2 is connected to a power source, current flows from the positive pin 21 of the body 20 into the light emitting chip in the body 20, and then flows out from the negative pin 22 of the body 20, so that the light emitting element 2 is turned on and emits light. The light emitting element 2 may be made of different semiconductor materials, thereby emitting light of different colors.

[0052] In some embodiments, among any two adjacent light-emitting elements 2, the positive electrode pin 21 of one light-emitting element 2 is connected to the negative electrode pin 22 of the other light-emitting element 2 through a wiring 3, so that multiple light-emitting elements 2 are connected in series on the flexible board 1, so that the light emission of multiple light-emitting elements 2 can be controlled simultaneously. Among them, the wiring 3 is arranged on the flexible board 1, and can be formed by a copper foil layer arranged on the flexible board 1, which is conductive and can electrically connect the positive electrode pin 21 and the negative electrode pin 22, so that each light-emitting element 2 can be turned on, and the wiring 3 itself is relatively thin and has a certain flexibility.

[0053] In this embodiment, the trace 3 includes at least a first section 31 and a second section 32 connected to each other, and an angle is formed between the first section 31 and the second section 32, so that the trace 3 is at least partially bent rather than a directly connected horizontal section. In this way, when the flexible board 1 is curled, the stress will be dispersed at the connection between the first section 31 and the second section 32, that is, the bending part of the trace 3, and will not be directly transmitted to the connection between it and the pin of the light-emitting element 2, thereby avoiding the breakage or damage of the trace 3 due to stress concentration, thereby ultimately improving the reliability of the light board and enhancing the user experience.

[0054] In some embodiments, the first section 31 and the second section 32 may be arranged at an acute angle or at a right angle. For example, when the trace 3 only includes the first section 31 and the second section 32, one end of the first section 31 may be connected to the negative electrode pin 22, one end of the second end may be connected to the positive electrode pin 21, and the other end of the first section 31 is connected to the other end of the second section 32, and the two are arranged at a right angle. When the light board is rolled, the stress is dispersed at the connection between the first section 31 and the second section 32, and will not be directly transmitted to the connection with the positive electrode pin 21 or the negative electrode pin 22.

[0055] In some embodiments, the connection line between one end of each body 20 provided with a positive pin 21 and one end of the body 20 provided with a negative pin 22 extends along the width direction of the flexible board body 1, so that the light-emitting element 2 is longitudinally arranged on the flexible body 20. Since each light-emitting element 2 is arranged at intervals along the length direction of the flexible body 20, such an arrangement will cause the wiring 3 to at least partially extend along the width direction of the flexible board body 1 to be led out, and the wiring 3 also at least partially extends along the length direction of the flexible board body 1 so as to be able to connect with the pins on the adjacent light-emitting element 2, so that the wiring 3 is at least partially bent, and ultimately the stress is dispersed at the bend.

[0056] In some embodiments, one end of the positive pin 21 or the negative pin 22 of each body 20 is located on the same side of each body 20 in the width direction of the flexible board body 1. For example, one end of the positive pin 21 of each body 20 is located on the upper side of each body 20 in the width direction of the flexible body 20, and one end of the negative pin 22 of each body 20 is located on the lower side of each body 20 in the width direction of the flexible board body 1. When adjacent light-emitting elements 2 are connected, the wiring 3 needs to connect the positive pin 21 of one light-emitting element 2 and the negative pin 22 of another light-emitting element 2, so that part of the wiring 3 is located between the two bodies 20, and the whole can be roughly Z-shaped, and the wiring 3 has more bent parts, so as to avoid stress transmission to the connection between the wiring 3 and the pin as much as possible.

[0057] In some embodiments, in order to facilitate the arrangement of the wiring 3 on the flexible board 1 and to avoid interference between the wirings 3 as much as possible, the wiring 3 further includes a third section 33 , a fourth section 34 and a fifth section 35 .

[0058] Specifically, one end of the first section 31 is connected to the negative electrode pin 22 and extends along the width direction of the flexible board body 1. The second section 32 is connected to the other end of the first section 31. The second section 32 extends along the length direction of the flexible board body 1. The first section 31 and the second section 32 are arranged at a right angle.

[0059] The third section 33 is connected to the end of the second section 32 away from the first section 31, and the third section 33 extends along the width direction of the flexible board body 1. The third section 33 is located between the bodies 20 of two adjacent light-emitting elements 2, and the third section 33 and the second section 32 are arranged at a right angle. The fourth section 34 is connected to the end of the third section 33 away from the second section 32, and the fourth section 34 extends along the length direction of the flexible board body 1, and the fourth section 34 and the third section 33 are arranged at a right angle. The fifth section 35 is arranged along the width direction of the flexible board body 1, and the two ends of the fifth section 35 are respectively connected to the other end of the fourth section 34 and the positive pin 21, and the fourth section 34 and the fifth section 35 are arranged at a right angle. By setting the first section 31, the second section 32, the third section 33, the fourth section 34 and the fifth section 35, the routing 3 can have multiple corners, which can disperse stress as much as possible to avoid the routing 3 from breaking when curling.

[0060] In some embodiments, the routing line 3 further includes a first inclined section 36, a second inclined section 37, a third inclined section 38 and a fourth inclined section 39. The end of the first section 31 is connected to the end of the second section 32 through the first inclined section 36, and the first inclined section 36 and the first section 31 and the second section 32 are arranged at an angle.

[0061] In some embodiments, the first inclined section 36 can be inclined toward the third section 33 or away from the third section 33. In this embodiment, the first inclined section 36 is inclined toward the third section 33 to form an angle with the first section 31 and the second section 32.

[0062] In some embodiments, the end of the second section 32 is connected by the second inclined section 37 and the end of the third section 33, and the second inclined section 37 is arranged at an angle to the second section 32 and the third section 33. The second inclined section 37 can be inclined toward the direction of the third section 33, or can be inclined in a direction away from the first section 31. In this embodiment, the second inclined section 37 is inclined toward the direction of the first section 31.

[0063] In some embodiments, the end of the third section 33 is connected through the third inclined section 38 and the end of the fourth section 34, and the third inclined section 38 is arranged at an angle to the third section 33 and the fourth section 34. The third inclined section 38 can be inclined toward the direction of the fifth section 35 or the direction of the first section 31. In this embodiment, the third inclined section 38 is inclined toward the direction of the fifth section 35.

[0064] In some embodiments, the end of the fourth section 34 is connected through the fourth inclined section 39 and the end of the fifth section 35, and the fourth inclined section 39 and the fourth section 34 and the fifth section 35 are arranged at an angle. Among them, the fourth inclined section 39 can be inclined in the direction of the third section 33, or can be inclined in the direction away from the third section 33. In this embodiment, the fourth inclined section 39 is inclined in the direction away from the third section 33. The inclination angles of the first inclined section 36, the second inclined section 37, the third inclined section 38 and the fourth inclined section 39 can be acute angles, such as 45°, so as to facilitate the routing of the line 3.

[0065] See also Figure 4 In some embodiments, the flexible board body 1 may also be a double-sided circuit board structure, and the light-emitting elements 2 are all arranged on the same side of the flexible board body 1. The trace 3 may also include only the first section 31, the second section 32, the third section 33, the first inclined section 36, the second inclined section 37 and the third inclined section 38. A conductive drilled hole 5 may be provided at one end of the third inclined section 38 away from the second section 32. The conductive drilled hole 5 is connected to the trace 3 arranged on the other side of the flexible body 20 where the light-emitting element 2 is not arranged, and is connected to the positive pin 21 of the adjacent light-emitting element 2 on the other side through the trace 3, thereby avoiding the trace 3 interference caused by setting all the traces 3 on one side of the flexible board body 1 due to too many light-emitting elements 2.

[0066] In some embodiments, the light-emitting element 2 may be a multi-pin LED lamp bead, and different light-emitting chips are encapsulated inside the body 20 thereof so as to emit light of different colors. Accordingly, a plurality of positive pins 21 are provided, which are respectively the first positive pin 211 to the Nth positive pin sequentially arranged along the length direction of the flexible board body 1, and a plurality of negative pins 22 are provided, which are respectively the first negative pin 221 to the Nth negative pin sequentially arranged along the length direction of the flexible board body 1, and the first positive pin 211 to the Nth positive pin correspond to the first negative pin 221 to the Nth negative pin one by one, such as the first positive pin 211 corresponds to the first negative pin 221, and the Nth positive pin corresponds to the Nth negative pin.

[0067] It can be understood that in order to connect two adjacent light-emitting elements 2, multiple routing lines 3 are provided, namely the first routing line to the Nth routing line. Among any two adjacent light-emitting elements 2, the Nth positive pin of one light-emitting element 2 is connected to the Nth negative pin of the other light-emitting element 2 through the Nth routing line, where N can be one, two, three or four, etc. The structures of the first routing line to the Nth routing line are the same, and the difference is that they are used to connect different positive pins 21 and negative pins 22.

[0068] In some embodiments, in the first routing to the Nth routing, the extension lengths of the corresponding first segments 31 increase successively, while the extension lengths of the corresponding second segments 32 decrease successively, so that when multiple positive pins 21 and negative pins 22 are set, the first routing to the Nth routing can be arranged more compactly, thereby avoiding interference.

[0069] In this embodiment, N can be three, so that the light-emitting element 2 can be a six-pin LED lamp bead, which has three pairs of corresponding positive pins 21 and negative pins 22. The main body 20 is provided with light-emitting chips corresponding to the three primary colors, so as to be able to emit three different colors of light, such as red, green and blue. Among them, the first positive pin 211 and the first negative pin 221 are connected to each other to emit green light, the second positive pin 212 and the second negative pin 222 are connected to each other to emit red light, and the third positive pin 213 and the third negative pin 223 are connected to each other to emit blue light. By controlling the magnitude of the current flowing through different positive and negative electrodes, different colors can be mixed.

[0070] In this embodiment, in order to make the light board emit more colors and meet more personalized lighting needs, the light-emitting element 2 can also be a yellow LED lamp bead and a white LED lamp bead. A plurality of yellow LED lamp beads and white LED lamp beads can be provided, which are arranged at intervals along the length direction of the flexible board 1. The yellow LED lamp bead and the white LED lamp bead can emit yellow light and white light respectively. They both include the above-mentioned body 20 and the positive pin 21 and the negative pin 22 arranged at the opposite ends of the body 20. The positive pin 21 and the negative pin 22 between adjacent yellow LED lamp beads are connected through the above-mentioned wiring 3, and the positive pin 21 and the negative pin 22 between adjacent white LED lamp beads are connected through the above-mentioned wiring 3. The specific structure of the wiring 3 is not repeated here.

[0071] Among them, multiple yellow LED lamp beads and white LED lamp beads form two columns of light strips along the length direction of the flexible board 1, and multiple six-pin LED lamp beads are located between the two columns of light strips. During lighting, the corresponding light-emitting elements 2 can be turned on as needed to obtain the desired light-emitting color. At the same time, different light-emitting elements 2 can be controlled to turn on at the same time to obtain different color temperatures.

[0072] In some embodiments, a resistor element 4 is connected between two adjacent bodies 20 , and opposite ends of the resistor element 4 are respectively connected to the trace 3 , so that the resistor and the light-emitting element 2 are connected in series, which can provide current limiting protection for the light-emitting element 2 .

[0073] In some embodiments, the connections at both ends of the resistor element 4 connected to the trace 3 extend along the width direction of the flexible board body 1, so that the resistor element 4 can be compactly installed between the two bodies 20. The resistor element 4 can be connected to the third section 33 of the trace 3 to avoid stress being transferred to the connection between the trace 3 and the resistor element 4 when the light board is curled.

[0074] See also Figure 5 In some embodiments, for a light emitting element 2 with a small number of pins, such as only a pair of positive pins 21 and negative pins 22, the light emitting elements 2 may be arranged in other ways to avoid stress concentration in the wiring 3.

[0075] For example, the connection between one end of the body 20 of each light emitting element 2 provided with the positive electrode pin 21 and one end of the body 20 provided with the negative electrode pin 22 extends along the length direction of the flexible board body 1. At this time, among any two adjacent light emitting elements 2, the positive electrode pin 21 of one light emitting element 2 and the negative electrode pin 22 of the other light emitting element 2 are arranged opposite to each other.

[0076] When the trace 3 connects the positive pin 21 and the negative pin 22, one end of the first section 31 is connected to the negative pin 22, the first section 31 extends along the length direction of the flexible board body 1, and the second section 32 is connected to the other end of the first section 31, and the second section 32 extends along the width direction of the flexible board body 1, and the second section 32 and the first section 31 are arranged at a right angle.

[0077] The third section 33 is connected to the end of the second section 32 away from the first section 31 , and extends along the length direction of the flexible board 1 . The third section 33 is located between the bodies 20 of two adjacent light emitting elements 2 , and the third section 33 and the second section 32 are arranged at a right angle.

[0078] The fourth section 34 is connected to the end of the third section 33 away from the second section 32 . The fourth section 34 extends along the width direction of the flexible board body 1 . The fourth section 34 and the third section 33 are arranged at a right angle.

[0079] The fifth section 35 extends along the length direction of the flexible board body 1, and the two ends of the fifth section 35 are respectively connected to the other end of the fourth section 34 and the positive pin 21, and the fifth section 35 and the fourth section 34 are arranged at a right angle, so that the wiring 3 has multiple corners, which can well disperse the stress. When the number of pins is small, such a setting can also avoid the wiring 3 from breaking due to stress concentration when curling.

[0080] In some embodiments, a power terminal 11 and a light-emitting element common terminal 12 are also provided at one end of the flexible board body 1 in the length direction. The light-emitting element 2 close to the power terminal 11 is electrically connected to the power terminal 11, and the light-emitting element 2 far from the power terminal 11 is electrically connected to the light-emitting element common terminal 12 to form a light-emitting circuit. After the power is connected, the light-emitting element 2 can emit light.

[0081] In some embodiments, a plurality of light emitting element common ends 12 may be provided along the width direction of the flexible board 1, corresponding one-to-one to light emitting elements 2 emitting light of different colors, so that light emitting elements 2 of different colors form independent light emitting circuits, thereby being able to independently control light emission.

[0082] This embodiment also discloses an inflatable stick lamp. The inflatable stick lamp comprises a shell and the above-mentioned lamp board. The shell is the main structure of the inflatable stick lamp.

[0083] In some embodiments, the shell is hollow and has an inflatable air chamber inside, and the shell can be inflated to expand and thus be shaped. When the inflatable stick light is needed, the shell is inflated to expand and form into a column or ring, etc., and when it needs to be stored, the air in the air chamber can be discharged to curl it up for storage.

[0084] In some embodiments, the light board is arranged on the housing, and the light board extends along the axis direction of the housing, so that when the housing is stored, the light board can be curled together with the housing. The light board can be arranged inside the housing, and the light emitted by the light-emitting element 2 on the light board is transmitted through the housing. The light board can also be directly arranged on the outer wall of the housing, and the light emitted by the light-emitting element 2 on the light board is emitted outward.

[0085] In this embodiment, the wiring 3 on the lamp board is segmented to include at least a first segment 31 and a second segment 32. When the inflatable stick lamp is curled, the lamp board curls with the shell and the stress on the wiring 3 on the lamp board is dispersed at the connection between the first segment 31 and the second segment 32, thereby avoiding breakage of the wiring 3 when curling, thereby improving the reliability of the lamp board and the inflatable stick lamp.
