Description

Technical Field

[0001] This utility model relates to the field of exhibition lighting technology, specifically to a lighting device for exhibitions and conventions. Background Technology

[0002] In the exhibition and convention industry, the flexibility and adaptability of lighting equipment are key factors in enhancing the exhibition effect. Traditional lighting systems mostly adopt fixed installation structures, making it difficult to quickly adjust the lamp angle and lighting range according to the booth layout, exhibit characteristics, or visitor movement. This results in insufficient or excessive lighting in some areas, affecting the visual experience and information reception efficiency of exhibitors. In existing technologies, some adjustable lighting equipment achieves angle adjustment through electric drive mechanisms or hydraulic devices. However, such solutions have drawbacks such as complex structure, high cost, and difficult maintenance. They also require additional control systems and energy supply modules, making it difficult to meet the rapid deployment requirements of exhibition and convention scenarios. To address these pain points, this technical solution innovatively proposes a lighting equipment for exhibitions and conventions. Utility Model Content

[0003] The purpose of this utility model is to provide a technical solution for lighting equipment used in exhibitions and conventions, thereby addressing the shortcomings mentioned in the background art. To overcome the drawbacks and defects described in the background art, this technical solution includes the following:

[0004] It includes a lamp hanging mechanism, wherein 10-16 sets of lamp tube fixing brackets are movably hinged in a circular array on the four sides of the lamp hanging mechanism.

[0005] The lamp hanging mechanism includes a hollow steel pipe, a threaded section on the upper half of the outer ring of the hollow steel pipe, and an internally threaded sleeve screwed onto the outer ring of the threaded section. A fixed sleeve is fixedly connected to the bottom section of the outer ring of the hollow steel pipe, and a cylindrical spring is fixed on the side of the movable sleeve and the fixed sleeve that are close to each other, which is fitted onto the bottom of the outer ring of the hollow steel pipe.

[0006] Each of the lamp tube fixing brackets includes a long support arm with its inner end hinged to the outer ring surface of the fixing sleeve, and a short support arm with its inner end hinged to the outer ring surface of the movable sleeve. The outer end of the short support arm is hinged to the middle section of the upper surface of the long support arm.

[0022] To provide a clearer explanation and description of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of each embodiment. Specific details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures. The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0024] Example 1: The exhibition lighting equipment consists of a lamp hanging mechanism 1 and a ring-shaped array of lamp fixing brackets 2 forming the basic structure. The lamp hanging mechanism 1 uses a hollow steel pipe 11 as the main support component, with a ceiling connecting plate 14 welded to its top. This connecting plate is fixed to the exhibition booth ceiling by screws in the four corner protrusions. The upper half of the outer ring of the hollow steel pipe 11 is provided with a threaded section 13. The bottom of the screw-fit internal threaded sleeve 15 contacts the top of the movable sleeve 16. The movable sleeve 16 passes through the hollow steel pipe 11 and forms a sliding fit. The fixed sleeve 18 is welded to the bottom of the hollow steel pipe 11, and a cylindrical spring 19 is installed between it and the movable sleeve 16 to form an adjustable height elastic support structure. Twelve fan-shaped protrusions 12 are evenly distributed on the outer ring of the movable sleeve 16 and the fixed sleeve 18. Each protrusion is embedded with an iron ring 17 for hinged connection of the lamp fixing brackets 2. The lamp tube fixing bracket 2 consists of a long arm 21 and a short arm 22. The inner end of the long arm 21 is hinged to the fan-shaped protrusion 12 of the fixing sleeve 18 through an iron ring 17. The inner end of the short arm 22 is hinged to the fan-shaped protrusion 12 of the movable sleeve 16 through an iron ring 17. The outer ends of the two arms form a hinge structure that can rotate relative to each other through a shaft pin. Three LED lamp tubes 23 are installed at the bottom of the long arm 21. All lamp tube power lines are connected to the external power bus through the internal cavity of the hollow steel tube 11.

[0025] Example 2: Based on the basic structure, optimizations are made. The hollow steel pipe 11 of the lamp holder mechanism 1 adopts a segmented design, and the threaded section 13 is welded to the main pipe to strengthen the connection. The surface of the internal threaded sleeve 15 is provided with anti-slip texture to improve the convenience of screwing operation. The cylindrical spring 19 between the movable sleeve 16 and the fixed sleeve 18 adopts a double-layer superimposed structure to enhance the elastic buffering effect. The number of fan-shaped protrusions 12 is adjusted to 16, evenly distributed on the 360° circumference. The surface of the iron ring 17 inside each protrusion is nickel-plated to improve wear resistance and rotation smoothness. Two LED lamp tubes 23 are installed at the bottom of the long support arm 21 of the lamp tube fixing bracket 2, and the length of the short support arm 22 is shortened by 10%, making the overall structure more compact. The LED lamp tubes 23 adopt detachable quick-connect plugs for easy maintenance and replacement.

[0026] Example 3: A reinforced structure is designed for large-scale exhibition scenarios. The hollow steel pipe 11 of the lighting fixture hanging mechanism 1 features a thickened wall design, increasing its diameter to 1.5 times the standard specification. Reinforcing ribs are added to the ceiling connecting plate 14, which is fixed to the exhibition booth ceiling using six sets of expansion bolts. A double spring assembly is installed between the movable sleeve 16 and the fixed sleeve 18, each assembly containing three parallel cylindrical springs 19 to enhance load-bearing capacity. The number of fan-shaped protrusions 12 is increased to ten, made of high-strength engineering plastic, and the internal iron rings 17 are replaced with stainless steel. Four LED tubes 23 are installed at the bottom of the long arm 21 of the lamp tube fixing bracket 2. An angle limiting device is added to the hinge point between the short arm 22 and the long arm 21, allowing locking at any angle within the range of 0°-90°. All LED tubes 23 are equipped with independent dimming modules, achieving centralized control via signal lines within the hollow steel pipe 11.

[0027] Example 4: An adjustable structure is designed to meet specific styling requirements. The hollow steel tube 11 of the lamp holder mechanism 1 adopts a telescopic design with multiple nested sleeves, allowing the total length to be adjusted within a range of 2-4 meters. A hydraulic damping device is added between the movable sleeve 16 and the fixed sleeve 18, replacing the traditional cylindrical spring 19 to achieve precise height adjustment. The fan-shaped protrusions 12 are designed as a rotatable structure, with each protrusion connected to the hollow steel tube 11 via a bearing, allowing for independent angle adjustment. The long arm 21 and short arm 22 of the lamp tube fixing bracket 2 are made of shape memory alloy, automatically retracting in low-temperature environments and automatically expanding in high-temperature environments, creating dynamic shape changes. The LED lamp tube 23 uses a flexible circuit board, which can bend and deform with the support arms, and, in conjunction with a programmable controller, achieves dynamic changes in lighting effects.

[0028] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0029] During installation, the ceiling connecting plate 14 is first fixed to the ceiling of the exhibition stand using screws in the four corner protrusions. The hollow steel pipe 11 extends vertically downward as the main support component, and the ceiling connecting plate 14 welded to its top bears the weight of the entire equipment. The threaded section 13 is located on the upper half of the outer ring of the hollow steel pipe 11, and the internal threaded sleeve 15 is screwed onto the threaded section 13. The axial position of the internal threaded sleeve 15 is adjusted by rotation, and its bottom contacts and applies pressure to the top of the movable sleeve 16. The movable sleeve 16 passes through the hollow steel pipe 11 and can slide axially. The cylindrical spring 19 installed between the movable sleeve 16 and the fixed sleeve 18 is compressed or stretched to form an elastic support force, keeping the movable sleeve 16 in a dynamically balanced position.

[0030] The fixed sleeve 18 is welded to the bottom of the hollow steel pipe 11, forming the hinged base of the lamp tube fixing bracket 2 together with the movable sleeve 16. Iron rings 17 are embedded inside the evenly distributed fan-shaped protrusions 12 on the outer rings of the movable sleeve 16 and the fixed sleeve 18. The inner end of the long support arm 21 is hinged to the fan-shaped protrusions 12 of the fixed sleeve 18 via the iron rings 17, and the inner end of the short support arm 22 is hinged to the fan-shaped protrusions 12 of the movable sleeve 16 via the iron rings 17. The middle section of the upper surface of the long support arm 21 and the outer end of the short support arm 22 form a hinged structure that allows relative rotation via a pivot pin. When the movable sleeve 16 undergoes axial displacement under the action of the cylindrical spring 19, the short support arm 22 moves synchronously with the movable sleeve 16, while the long support arm 21 remains relatively stable due to the constraint of the fixed sleeve 18. The included angle between the two arms changes accordingly, causing the lamp tube fixing bracket 2 to swing as a whole.

[0031] The swing of the lamp tube fixing bracket 2 is transmitted to the LED lamp tube 23 installed at the bottom through a hinge structure. Multiple lamp tube fixing brackets 2 are arranged in a circular array, and their swing amplitude and direction are determined by the displacement of the movable sleeve 16 and the elastic coefficient of the cylindrical spring 19. The power line of the LED lamp tube 23 is connected to the external power bus through the cavity inside the hollow steel tube 11, and the signal line can transmit control commands synchronously. When it is necessary to adjust the lighting range, the position of the movable sleeve 16 can be changed by rotating the internal threaded sleeve 15, thereby adjusting the tilt angle of the lamp tube fixing bracket 2 so that the light direction of the LED lamp tube 23 covers different areas.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
