Description

Technical Field

[0001] This invention relates to the field of linear lighting technology, specifically to an assembled rectangular linear lighting. Background Technology

[0002] A rectangular linear light is an LED lighting fixture that is elongated and has a decorative lighting effect. Existing linear lights, such as the waterproof linear light disclosed in Chinese patent application CN209116062U, describe a light body comprising multiple LED beads arranged at intervals along the length of the light body, resulting in good energy efficiency. A waterproof sleeve has a hollow cavity, within which the linear light body is housed, providing a degree of waterproofing. In this embodiment, the waterproof sleeve is a silicone sleeve, which offers excellent waterproofing and light transmittance. One end of the waterproof sleeve has an opening through which the linear light body can be placed inside. Transparent waterproof adhesive is filled inside the waterproof sleeve and covers the linear light body. The transparent waterproof adhesive is formed by injecting waterproof adhesive into the waterproof sleeve and then curing it, so that the transparent waterproof adhesive covers the linear light body, enabling the interior of the waterproof linear light to achieve a better waterproof effect. The transparent waterproof adhesive allows the waterproof linear light to be used in some specific places with high waterproof requirements, meeting the high waterproof requirements of customers. For example, as described in the above patent, the linear lights in the prior art cannot be assembled horizontally, and therefore, the width of the linear light cannot be changed by assembly during installation, resulting in poor decorative flexibility. Summary of the Invention

[0003] The purpose of this invention is to provide a modular rectangular linear light to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a modular rectangular linear light, comprising a linear light housing, a light-diffusing cover plate, a sealing end plate, a mounting buckle, a mounting slot, an LED light bead circuit board, and a control airbag. The light-diffusing cover plate is fixedly installed on the upper part of the linear light housing. Sealing end plates are respectively installed at both ends of the linear light housing. A mounting buckle is fixedly provided on one side surface of the linear light housing, and a mounting slot is provided on the other side surface of the linear light housing. An LED light bead circuit board is disposed inside the linear light housing. A control airbag is connected and disposed below the LED light bead circuit board. The control airbag can control and change the distance between the LED light bead circuit board and the light-diffusing cover plate. An air pressure distribution structure is provided inside and outside the linear light housing, and the air pressure distribution structure can inflate and deflate the control airbag.

[0005] The air pressure distribution structure includes a housing base, an airflow exchange chamber, a piston block, an airtight threaded hole, a threaded screw, a sealing perforation, a positioning blind hole, an adjusting cap, an internal hexagon countersunk hole, a pad edge, a main air supply chamber, a connecting slot, a branch transverse chamber, an airbag bottom hole, an air chamber bottom hole, and a rubber plug.

[0006] The housing base is fixedly installed on the lower inner surface of the linear lamp housing. An airflow exchange chamber is provided inside the housing base, and a piston block is provided inside the airflow exchange chamber. The outer surface of the piston block is in sealed contact with the inner wall surface of the airflow exchange chamber.

[0007] The piston block has a through-hole with an airtight threaded hole, and a threaded screw is helically installed inside the airtight threaded hole. The inner wall surface of the airflow exchange chamber has a through-hole with a sealing perforation. The threaded screw passes through the sealing perforation and is in sealing contact with it. A positioning blind hole is provided on the inner wall surface of the airflow exchange chamber at the end away from the sealing perforation. The other end of the threaded screw is inserted into the positioning blind hole.

[0008] An adjusting cap is fixedly provided at the end of the threaded screw, and an internal hexagon countersunk hole is provided at the end of the adjusting cap. A pad ridge is fixedly provided on the upper surface of the housing base, and an air supply chamber is provided inside the pad ridge. A connecting slot is provided between the air supply chamber and the air exchange chamber, and the connecting slot is located at the end of the air exchange chamber near the positioning blind hole.

[0009] A branch transverse cavity is provided between the main air supply cavity and the airflow exchange cavity. An airbag bottom hole is provided below the control airbag. An air chamber bottom hole is provided on the lower surface of the main air supply cavity. The airbag bottom hole is connected to the air chamber bottom hole through the branch transverse cavity. A through hole is provided on the inner wall surface of the end of the airflow exchange cavity away from the positioning blind hole. A rubber plug is inserted and fixed in the through hole.

[0010] The inner wall surface of the linear lamp housing is fixedly provided with a cover plate retaining edge, and the lower surface of the light-diffusing cover plate is provided with a cover plate retaining rim, which is fixedly engaged inside the cover plate retaining edge.

[0011] The surface of the sealing end plate is fixedly provided with a conformal insertion rib, and the sealing end plate is fastened to both ends of the linear lamp housing through the conformal insertion rib. A power supply line hole is opened through the surface of the sealing end plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The linear light of this invention, through the interlocking of the assembly buckles and slots, allows for the assembly and combination of the linear light, changing the horizontal width of the linear light and making it suitable for more decorative and lighting applications.

[0014] Furthermore, the position of the LED lamp bead circuit board can be adjusted by the control airbag. When the LED lamp bead circuit board is close to the light-diffusing cover plate, the light-diffusing cover plate can transmit light in a light spot shape, which is more decorative. When the LED lamp bead circuit board is far away from the light-diffusing cover plate, the light-diffusing cover plate can transmit light more evenly, in a soft bright strip shape. With the support of the control airbag, the LED lamp bead circuit board has a better shock resistance and is suitable for mobile installation places such as vehicles. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 7 This invention provides a technical solution: a modular rectangular linear light, comprising a linear light housing 1, a light-diffusing cover plate 2, a sealing end plate 3, a mounting buckle 4, a mounting slot 5, an LED light bead circuit board 6, and a control airbag 7. The light-diffusing cover plate 2 is fixedly installed on the upper part of the linear light housing 1. Sealing end plates 3 are respectively installed at both ends of the linear light housing 1. A mounting buckle 4 is fixedly installed on one side surface of the linear light housing 1, and a mounting slot 5 is opened on the other side surface of the linear light housing 1. The mounting buckle 4 and the mounting slot 5 can be interlocked and fixed. An LED light bead circuit board 6 is disposed inside the linear light housing 1. The LED light bead circuit board 6 is a PCB circuit board, and LED light-emitting beads are embedded and soldered on its surface. A control airbag 7 is connected and disposed below the LED light bead circuit board 6. The control airbag 7 is as follows: Figure 3 As shown, it is cylindrical with corrugated sidewalls. When air pressure is input, the control airbag 7 can extend to support, and when negative pressure is input, the control airbag 7 will contract and shorten. The control airbag 7 can control and change the distance between the LED lamp bead circuit board 6 and the light distribution cover plate 2. The inner and outer sides of the linear lamp housing 1 are provided with an air pressure distribution structure, which can inflate and deflate the control airbag 7.

[0025] The air pressure distribution structure includes a housing base 101, an airflow exchange chamber 102, a piston block 103, an airtight threaded hole 104, a threaded screw 105, a sealing perforation 106, a positioning blind hole 107, an adjusting cap 108, an internal hexagon countersunk hole 109, a pad ridge 110, a main air supply chamber 111, a connecting slot 112, a branch transverse chamber 113, an airbag bottom hole 114, an air chamber bottom hole 115, and a rubber plug 116. The housing base 101 is fixedly installed on the lower inner surface of the linear lamp housing 1. An airflow exchange chamber 102 is provided inside the housing base 101. The airflow exchange chamber 102 is elongated and extends along the length of the linear lamp housing 1. A piston block 103 is provided inside the airflow exchange chamber 102, and the outer surface of the piston block 103 is in sealed contact with the inner wall surface of the airflow exchange chamber 102.

[0026] The piston block 103 has a through-hole 104, and a threaded rod 105 is helically installed inside the through-hole 104. The through-hole 104 is an internal threaded through hole, and the threaded rod 105 is threaded into it. The inner wall surface of the airflow exchange chamber 102 has a through-hole 106, and the threaded rod 105 passes through the through-hole 106 and is in sealing contact with it. The threaded rod 105 is an external threaded rod, and the part of the threaded rod 105 that passes through the through-hole 106 is a smooth rod. A positioning blind hole 107 is provided on the inner wall surface of the end of the airflow exchange chamber 102 away from the sealing through-hole 106. The other end of the threaded rod 105 is inserted into the positioning blind hole 107. The positioning blind hole 107 plays a supporting and positioning role for the threaded rod 105, preventing the threaded rod 105 from shifting.

[0027] An adjusting cap 108 is fixedly installed at the end of the threaded screw 105. The adjusting cap 108 and the threaded screw 105 can be welded together, or they can be integrally formed by turning or casting during production. The end of the adjusting cap 108 is provided with an internal hexagon countersunk hole 109. A pad ridge 110 is fixedly installed on the upper surface of the housing base 101. The pad ridge 110 also serves as a support. When the control airbag 7 is fully contracted, the upper surface of the pad ridge 110 can also support the lower surface of the LED lamp bead circuit board 6, so as to prevent the control airbag 7 from aging and tilting due to providing support for a long time during long-term storage. The pad ridge 110 has an air supply chamber 111 inside. A connecting slot 112 is provided between the air supply chamber 111 and the airflow exchange chamber 102. The connecting slot 112 is located at the end of the airflow exchange chamber 102 near the positioning blind hole 107. Gas exchange between the air supply chamber 111 and the airflow exchange chamber 102 can be realized through the connecting slot 112.

[0028] A branch transverse cavity 113 is provided between the main air supply cavity 111 and the airflow exchange cavity 102. An airbag bottom hole 114 is provided below the control airbag 7. An air chamber bottom hole 115 is provided on the lower surface of the main air supply cavity 111. The airbag bottom hole 114 is connected to the air chamber bottom hole 115 through the branch transverse cavity 113. A through hole is provided on the inner wall surface of the end of the airflow exchange cavity 102 away from the positioning blind hole 107. A rubber plug 116 is inserted and fixed in the through hole. The above-mentioned through hole can play a role in equalizing air pressure when the piston block 103 moves. The rubber plug 116 can play a sealing role after adjustment, preventing gas leakage from affecting the support position of the control airbag 7. At the same time, the rubber plug 116 can also play a dustproof role.

[0029] A cover plate retaining ridge 117 is fixedly installed on the inner wall surface of the linear lamp housing 1. The cover plate retaining ridge 117 is as follows: Figure 3As shown, the cover plate clips 117 are symmetrically distributed on both sides of the inner wall surface of the linear lamp housing 1. Each side of the cover plate clip 117 has at least two protruding clips. The lower surface of the light-diffusing cover plate 2 is provided with a cover plate clip 201, which is clipped and fixed inside the cover plate clip 117 and located between the two protruding clips.

[0030] The sealing end plate 3 is fixedly provided with a conformal insertion rib 301. The sealing end plate 3 is fastened to both ends of the linear light housing 1 through the conformal insertion rib 301. A power supply wire hole 302 is opened through the surface of the sealing end plate 3. The power supply wire hole 302 completely penetrates the sealing end plate 3. The power supply wire hole 302 can be any shape such as rectangular or circular. The wire passes through the power supply wire hole 302 for wiring. In order to enhance the sealing performance of the linear light housing 1, a rubber ring can be set between the wire and the power supply wire hole 302, thereby improving the waterproof and dustproof effect of the linear light.

[0031] In use, the power supply wires of the LED lamp bead circuit board 6 pass through the power supply wire hole 302, and the sealing end plate 3 is fixed at both ends of the linear lamp housing 1 to prevent light leakage. During assembly, the assembly clip 4 of one linear lamp is inserted into the assembly clip slot 5 of another linear lamp, thereby increasing the width of the linear lamp and making it suitable for more decorative and lighting applications. The structure of the light-diffusing cover plate 2 is as follows: Figure 2 As shown, the two side surfaces of the uniform light cover plate 2 are flush with the two side surfaces of the linear lamp housing 1, thereby reducing seams during horizontal assembly.

[0032] According to the decorative requirements of the lighting location, by changing the position of the LED lamp bead circuit board 6, the light transmission of the light distribution cover 2 can be made into a light spot or a more uniform and soft bright strip, and the two can be adjusted without any level.

[0033] During adjustment, remove the rubber stopper 116 and insert a hex wrench into the internal hexagon countersunk hole 109. Rotate the adjusting cap 108. Since the adjusting cap 108 and the threaded rod 105 are fixedly installed, when the adjusting cap 108 rotates, it drives the threaded rod 105 to rotate. When the threaded rod 105 rotates, through the helical engagement between the threaded rod 105 and the airtight threaded hole 104, it drives the piston block 103 to move inside the airflow exchange chamber 102. Because the outer surface of the piston block 103 is in sealed contact with the inner wall surface of the airflow exchange chamber 102, the movement of the piston block 103... At that time, by using the piston movement, the airflow in the airflow exchange chamber 102 can be sent into the air supply main chamber 111 through the connecting slot 112. The gas in the air supply main chamber 111 passes through the air chamber bottom hole 115, the branch transverse chamber 113 and the air bag bottom hole 114 in sequence into the control air bag 7, causing the control air bag 7 to expand and elongate, thereby supporting the LED lamp bead circuit board 6 and bringing the LED lamp bead circuit board 6 closer to the light uniform cover plate 2. At this time, the light reflected by the LED lamp beads on the surface of the LED lamp bead circuit board 6 will form dot-shaped light spots on the surface of the light uniform cover plate 2, which is more decorative.

[0034] When the adjustment cap 108 is reversed, the piston block 103 moves in the opposite direction, causing the airflow exchange chamber 102 to draw back the gas in the main air supply chamber 111 through the connecting slot 112. At this time, the control airbag 7 is drawn back and shortened, causing the LED lamp bead circuit board 6 to move away from the light uniform cover plate 2. At this time, the light reflected by the LED lamp beads on the surface of the LED lamp bead circuit board 6 will be more uniform on the surface of the light uniform cover plate 2, and it has the ability to adjust without gears. With the support of the control airbag 7, the LED lamp bead circuit board 6 is flexibly suspended inside the linear lamp housing 1, so that the LED lamp bead circuit board 6 has stronger shock resistance and drop resistance.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
