Description

Technical Field

[0001] The present invention relates to a linear lamp, in particular to a linear lamp with a radial sealing structure and an installation method thereof, belonging to the technical field of lighting equipment. Background Art

[0002] The linear light series is a high-end flexible decorative light characterized by low power consumption, long life, high brightness, and maintenance-free operation. It is particularly suitable for indoor and outdoor entertainment venues, building outlines, and billboard construction. In linear light lighting applications, waterproof performance has always been a key indicator of product quality. Most common linear light products on the market use a waterproof sealing structure that uses rubber gaskets to assemble and seal the lamp body, lampshade, and end caps. The rubber gaskets are placed between the lamp body, lampshade, and end caps, with the surface of the rubber gaskets designed to correspond to the concave and convex ends of the lamp body and lampshade. Fastening screws are used to assemble the end caps with the lamp body and lampshade. The gaskets deform under pressure and fill the surrounding gaps, achieving a waterproof seal.

[0003] Although the above-mentioned waterproof sealing structure is relatively simple and convenient, it also has the following disadvantages: the sealing gasket and the end face sealing of the lamp have relatively concave and convex surfaces. When the flatness of the end face of the lamp is uneven due to improper processing or the end face of the lamp sealing is different from the shape or material of the sealing gasket, the metal end face will continue to cause destructive cutting of the sealing gasket under the action of the continuous pressure exerted by the fastening screw. The longer the use time, the worse the waterproof sealing performance of the linear lamp will be. In addition, the sealing gasket of this sealing structure will have a part of its edge outside the lamp housing when in use. Long-term exposure to sunlight and rain will also cause the waterproof sealing performance of this sealing structure to deteriorate, affecting various performance indicators of the lamp.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a linear light with good waterproof and sealing performance to overcome the shortcomings in current practical applications and meet current needs. Summary of the Invention

[0005] The present invention is mainly aimed at the above-mentioned problems existing in the prior art, and provides a linear light with a radial sealing structure. The linear light has a simple structure and is quick to assemble. It is equipped with a sealing device to ensure that the linear light has good waterproof sealing performance, and is equipped with a power supply module used in conjunction with the sealing device, thereby improving the safety performance of the linear light and reducing safety hazards.

[0006] The purpose of the present invention is mainly achieved through the following solutions:

[0007] A linear light with a radial sealing structure includes a lamp holder, a lighting device, a sealing device and a power supply module. The lighting device includes a light-transmitting, long strip lamp tube with openings at both ends and a PCB lamp board arranged in the lamp tube. The lamp tube is installed on the lamp holder, and the lamp holder is a long strip with an "H"-shaped cross-section. Sealing devices are installed at the openings at both ends of the lamp tube. The sealing device includes a front cover and a rear cover. The lamp tube openings of the front cover and the rear cover are internally provided with sealing rings and compression fixings with sealing and waterproof functions; the bottom of the front cover is provided with a power supply module connected to the external wires, and the power supply module is electrically connected to the PCB lamp board through a signal transmission device arranged in the front cover.

[0008] By adopting the above technical solution, the sealing ring and the clamping and fixing block are used in conjunction with each other, the clamping and fixing block will squeeze the inner wall of the sealing ring outward, causing the sealing ring to expand and fit tightly to the inner wall of the lamp tube, thereby sealing the lamp and preventing external water vapor from entering the interior of the lamp tube. Moreover, the sealing ring is inside the lamp tube and will not be affected by the external environment, which can increase the service life. The power supply module matched with the sealing device is convenient to draw power and has strong sealing, which improves the safety performance of the linear lamp and reduces safety hazards.

[0009] Preferably, the sealing ring is a hollow ring made of rubber material, and the sealing ring is located between the clamping fixture and the front cover and between the clamping fixture and the rear cover; the clamping fixture is provided with an extension surface protruding outward at one end away from the lamp tube, the sealing ring is sleeved on the extension surface, and the diameter of the outer wall of the extension surface is greater than the diameter of the inner wall of the sealing ring.

The extension surface matches the shape of the sealing ring, and the diameter of the outer wall of the extension surface is larger than the diameter of the inner wall of the sealing ring. In the process of tightening the clamping fixture and the front end cover, the extension surface of the clamping fixture block will squeeze the inner wall of the sealing ring in all directions, causing the sealing ring to expand and fit tightly to the inner wall of the lamp tube, resulting in a good sealing effect.

[0011] Preferably, the clamping fixture and the sealing ring are both inserted into the opening of the lamp tube, and the clamping fixture and the sealing ring are in contact with the inner wall of the lamp tube, and the clamping fixture is provided with a support opening for the PCB lamp board to extend out.

[0014] By adopting the above technical solution, the second fixing screw is used to fix the front cover or the rear cover on the lamp holder, and the first fixing screw is used to fix the clamping fixture on the inner side of the front cover or the rear cover. During the tightening process of the first fixing screw, the clamping fixture is pulled so that the extended surface of the clamping fixture is pressed into the middle of the sealing ring, squeezing the inner wall of the sealing ring to cause it to expand radially. The outer wall of the expanded sealing ring fits tightly against the inner wall of the lamp tube, thereby sealing the lamp and preventing external water vapor from entering the interior of the lamp tube. The radial pressure generated by the expansion of the sealing ring is utilized to achieve a better sealing effect.

[0015] Preferably, the front cover is provided with a mounting plate for fixing a signal transmission device, the signal transmission device includes a power supply board connected to the power supply module and a signal input and output pin header electrically connected to the power supply board, and the signal input and output pin header is electrically connected to the PCB light board.

[0016] By adopting the above technical solution, the power supply board is fixed on the mounting plate of the front cover. A contact electrically connected to the top of the power supply module is provided under the power supply board. The other end of the contact is electrically connected to the signal input and output pin header.

[0017] Preferably, the lamp stand comprises two side panels and a crossbeam located between the two side panels, and the crossbeam divides the space between the two side panels into an upper groove and a lower groove.

[0018] By adopting the above technical solution, the arrangement of the upper groove and the lower groove facilitates the installation of the lamp tube and the power module and the distribution of peripheral wires.

[0021] Preferably, a limiting notch is opened at the front end of the lower groove of the lamp holder to cooperate with the power supply module. The power supply module is installed in the lower groove through the limiting notch, and the external wires passing through the power supply module are passed through the lower groove.

[0022] By adopting the above technical solution, the power supply module is installed in the lower groove through the limiting notch, the entire linear light is neat and beautiful, and can ensure the stability of the linear light during the power supply process.

[0023] Preferably, both side walls of the front end cover are hinged with locking devices for facilitating fixing the power extraction module on the lamp stand.

[0024] By adopting the above technical solution, the upper end of the locking device is hinged to the side wall of the front cover, and the lower part is buckled to the bottom of the power supply module, so that the power supply module and the sealing device can be tightly buckled together, with a stable structure, good sealing and high power supply stability.

[0029] 4) Attach the sealing device on the end of the linear light equipped with the signal transmission device to the power module installed in step 1) to complete the installation.

[0030] Therefore, the present invention has the following advantages:

[0031] (1) The present invention abandons the traditional sealing structure in which the sealing ring contacts the outer end face of the lamp tube. Instead, the sealing ring is installed inside the lamp tube. The inner wall of the sealing ring is squeezed by the clamping fixture to cause it to expand. The radial pressure generated by the expansion causes the sealing ring to contact the inner wall of the lamp tube tightly, thereby sealing the linear lamp and preventing external water vapor from entering the interior of the lamp tube, thereby achieving a better sealing effect.

[0032] (2) The sealing reliability of the present invention is high. The external environment and the flatness of the sealing end surface of the lamp tube will not affect the sealing effect, which can increase the service life of the linear lamp and reduce maintenance costs.

[0033] (3) The power supply module of the present invention is used in conjunction with the sealing device, and the power supply module is fastened to the sealing device through the locking device, which can further improve the waterproof sealing of the linear light, and has good power supply stability, thereby improving the safety performance of the linear light and reducing safety hazards.

[0071] The working principle of the linear light with a radial sealing structure provided by the present invention is as follows: the first fixing screw 36 pulls the pressing and fixing block 34 during the tightening process, so that one end of the extended surface 341 of the pressing and fixing block 34 is pressed into the middle of the sealing ring 33, squeezing the inner wall of the sealing ring 33 to cause it to expand radially. The outer wall of the expanded sealing ring 33 is tightly fitted to the inner wall of the lamp tube 21. The radial pressure generated by the expansion of the sealing ring 33 has a good sealing effect, preventing external water vapor from entering the interior of the lamp tube 21, thereby sealing the linear light; because the lamp tube 21 is made of a plastic stretched profile, its tube wall is smooth and transparent. When the sealing ring 22 expands outward, due to the large internal area of ​​the lamp tube 21, when the local pressure on the tube wall is too high, part of the pressure will be dispersed, so that the tube wall of the lamp tube 21 will not be scratched. In addition, the inner wall of the lamp tube 21 will not damage the sealing ring 33, thereby affecting the sealing effect.

[0072] The above-mentioned method for installing a linear light with a radial sealing structure includes the following steps:

[0073] 1) Install the external wire 5 into the power extraction module 4, and the power extraction plate in the power extraction module 4 pierces the external wire 5;

[0074] 2) Slide the PCB into the lamp tube 21 through the slide groove 212 inside the lamp tube 21, and then install the assembled lighting device 2 into the upper groove of the lamp holder 1;

[0075] 3) Install the sealing device 3 on both ends of the lamp holder 1 and the lamp tube 21 and fasten them securely;

[0076] 4) Attach the sealing device 3 at one end of the linear light equipped with the signal transmission device 35 to the power module 4 installed in step 1), and secure the power module 4 to the sealing device 3 using the locking device 16 to complete the installation.
