Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to a light guide assembly device. Background Technology

[0002] Traditional lighting fixtures mostly use a single switch or simple brightness adjustment, offering extremely limited control over the direction of light. While some fixtures can alter the direction of light projection through mechanical structures such as blinds or adjustable lampshade angles, these methods have significant drawbacks. Mechanical structures are prone to wear and tear after frequent use, leading to decreased adjustment precision, and they also generate noise during operation, affecting the user experience. This noise interference is unacceptable, especially in noise-sensitive environments such as hospitals, libraries, and conference rooms.

[0003] Therefore, developing a light guide assembly that can flexibly and precisely control the direction of light while possessing good stability and low noise characteristics is of great practical significance. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model proposes a light guide combination device.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A light guide assembly includes a lampshade and a lighting lamp. Multiple electrically controlled dimming glass panes are disposed inside the lampshade and are arranged in a circular array around the lighting lamp. A control system is also provided inside the lampshade to control the transparency of each electrically controlled dimming glass pane.

[0007] Based on multiple electrically controlled dimming glass panes arranged in a circular array around a lighting lamp, the control system achieves flexible adjustment of the light direction by differentially controlling the transparency of each glass pane. When the control system sends an electrical signal to change the transparency of the electrically controlled dimming glass, it does so by changing the arrangement of liquid crystal molecules within the glass; the entire process involves no friction or movement of mechanical parts.

[0008] Traditional lighting fixtures offer limited control over light direction, and their mechanical adjustment methods have significant drawbacks. This light guide assembly, through its electrically controlled dimming glass and control system, enables flexible and precise control of light direction. In environments with strict requirements for light direction, such as museum displays of specific artifacts, it can precisely guide light to focus on the artifacts, enhancing the display effect while preventing unnecessary damage to the artifacts, thus improving the applicability of lighting fixtures in professional settings. Furthermore, this light guide assembly uses electrically controlled dimming glass, eliminating the wear and tear issues associated with mechanical parts and meeting the requirements for low-noise environments.

[0009] Preferably, the electronically controlled dimming glass includes a glass body, a metal film, and two conductive metal pillars. One end of the metal film extends into the inner cavity of the glass body, and the other end is fixedly connected to one of the conductive metal pillars.

[0010] When an external power source is connected, the current flows from one terminal of the power source, through one of the conductive metal posts, to a metal film fixedly connected to it. Since one end of the metal film extends into the inner cavity of the glass body, the current then passes through conductive materials such as the liquid crystal layer within the glass body, and is conducted through another metal film to its connected conductive metal post, finally returning to the other terminal of the power source, thus forming a complete current loop. The design of the conductive metal posts facilitates connection to external circuits. In actual installation, construction workers can more easily connect external wires to the conductive metal posts, reducing installation difficulty and complexity.

[0011] As a preferred option, the lampshade is equipped with a mounting base corresponding to each electronically controlled dimming glass. The mounting base is provided with a mounting groove. The top wall of the mounting groove is fixed with a positive terminal and a negative terminal connected to the control system. The mounting groove is also equipped with a fixing mechanism. When the glass body is fixed in the mounting groove, the two conductive metal pillars are connected to the positive terminal and the negative terminal respectively.

[0012] Each electrically adjustable glass panel is equipped with a dedicated mounting bracket inside the lampshade. During installation, the glass body is fixed within the mounting groove, and two conductive metal posts on the glass body connect to the positive and negative terminals fixed to the top wall of the mounting groove, respectively. Since the positive and negative terminals are connected to the control system, this establishes a circuit connection between the electrically adjustable glass and the control system via the mounting bracket. Electrical signals from the control system are transmitted to the electrically adjustable glass through this circuit, thereby controlling its transparency.

[0013] As a preferred embodiment, a mounting plate is fixed on the side wall of the glass body, and a threaded hole is provided on the side wall of the mounting plate. A connecting hole is provided on the side wall of the mounting base. When the glass body is fixed in the mounting groove, the threaded hole and the connecting hole are coaxial. The mounting base also includes a bolt, which can pass through the connecting hole and be screwed into the threaded hole.

[0014] The glass body is placed in the mounting slot of the mounting base, at which point the mounting plate fixed to the side wall of the glass body corresponds to the side wall of the mounting base. Because the threaded hole on the mounting plate is coaxial with the connecting hole on the side wall of the mounting base when the glass body is fixed in the mounting slot, maintenance personnel can pass bolts through the connecting hole on the side wall of the mounting base and then screw them into the threaded hole on the mounting plate. As the bolts are tightened, the mounting plate and the side wall of the mounting base fit tightly together, thus firmly fixing the glass body in the mounting slot. This method of connecting the mounting plate and the mounting base with bolts achieves stable installation of the glass body within the mounting base and facilitates easy disassembly.

[0015] Preferably, the lampshade includes a housing and a base plate. The lighting lamp, control system and mounting bracket are all fixed on the base plate. A threaded groove is provided on the lower end face of the base plate, and the housing can be screwed into the threaded groove to be fixed on the base plate.

[0016] This easy-to-disassemble and assemble structural design facilitates mass production, packaging, and transportation of the product. During production, the base plate and outer shell can be processed and pre-assembled separately, followed by rapid final assembly. During transportation, if the product is too large, the outer shell and base plate can be separated, reducing packaging volume and lowering transportation costs. Furthermore, this design allows users to easily install and disassemble the product themselves after purchase, increasing its user-friendliness.

[0017] Preferably, the cross-section of the glass body is arc-shaped, and the distance between the sidewalls of two adjacent glass bodies is between 0.5mm and 1mm.

[0018] The glass body has an arc-shaped cross-section, and the distance between the sidewalls of adjacent glass bodies is controlled between 0.5mm and 1mm. This design effectively controls light. Because the gap is small enough, less light passes through it; the 0.5mm-1mm gap provides sufficient space for the glass body to expand when heated. When it's hot, the glass body expands due to increased temperature, and the gap can accommodate this expansion, preventing damage such as cracking or deformation caused by mutual compression between the glass bodies. This ensures that the light guide assembly operates stably and reliably under different temperature conditions. Attached Figure Description

Detailed Implementation

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0026] Example

[0027] like Figures 1-4 As shown, the light guide assembly includes a lampshade and a lighting lamp. The lampshade consists of a housing and a base plate. A threaded groove is provided on the lower end face of the base plate, into which the housing can be screwed to secure it. The lighting lamp, control system, and mounting brackets corresponding to the various electrically controlled dimming glass units are securely mounted on the base plate.

[0028] Electrically controlled dimming glass: Each piece of electrically controlled dimming glass consists of a glass body, two metal films, and two conductive metal pillars. One end of each metal film extends into the glass body, and the other end is connected to one of the conductive metal pillars. A mounting plate is fixed to the side wall of the glass body, and the side wall of the mounting plate has threaded holes; the side wall of the mounting base has connecting holes. When the glass body is placed in the mounting groove of the mounting base, the threaded holes and connecting holes are coaxial. A bolt is then passed through the connecting hole and screwed into the threaded hole to firmly fix the glass body in the mounting groove.

[0029] Meanwhile, the top wall of the mounting groove is equipped with positive and negative terminals connected to the control system. After the glass body is properly installed, two conductive metal pillars will connect to the positive and negative terminals respectively. This embodiment has eight electrically controlled dimming glass panels, arranged in a circular array around the lighting lamp within the lampshade. Furthermore, the cross-section of the glass body is arc-shaped, and the distance between the sidewalls of adjacent glass panels is maintained at 0.5mm-1mm.

[0030] Application process and principle of light guide assembly

[0031] The principle of electrically controlled dimming glass: When an external power source is connected, current flows from one end of the power source, first passing through one of the conductive metal pillars, and then to a connected metal film. Since one end of the metal film is inside the glass body, the current passes through the liquid crystal layer and other conductive materials within the glass body, then through another metal film to the corresponding conductive metal pillar, finally returning to the other end of the power source, thus forming a complete current loop. The electrical signals emitted by the control system change the arrangement of the liquid crystal molecules within the glass, thereby controlling the transparency of the electrically controlled dimming glass. Electrically controlled dimming glass is existing technology and will not be elaborated upon here. When the control system emits a specific electrical signal, the liquid crystal molecules align in an orderly manner, increasing the glass's transparency and allowing light to pass through more easily; conversely, when the liquid crystal molecules are arranged disorderedly, the glass's transparency decreases, reducing the amount of light transmitted.

[0032] The control system flexibly adjusts the direction of light by differentially controlling the transparency of each electrically controlled dimming glass element arranged in a circular array around the lighting fixture. Different levels of transparency result in varying degrees of light refraction and obstruction. For example, when the transparency of one side of the electrically controlled dimming glass is higher, more light propagates in that direction; while the less transparent glass blocks some light, causing it to propagate in other directions. In this way, light can be precisely guided to specific areas.

[0033] Compared to traditional lighting fixtures, this device can precisely guide light. For example, when displaying artifacts in a museum, it allows the light to be accurately focused on the artifacts, enhancing the display effect while preventing damage from the light, greatly improving its applicability in professional settings. Because it uses electrically controlled dimming glass, the entire process of adjusting the light direction involves no friction or movement of mechanical parts. Unlike the mechanical adjustment methods of traditional lighting fixtures, which are prone to wear and tear and noise after prolonged use, this device can meet the needs of places with strict noise requirements, such as hospitals and libraries.

[0034] The bolted connection between the mounting plate and the mounting base ensures the stability of the glass body installation while facilitating disassembly when needed. The swivel-connected design of the lampshade housing and base plate allows for separate processing and pre-assembly of components during production, leading to rapid final assembly and improved production efficiency. During transportation, the housing and base plate can be separated, reducing packaging volume and lowering shipping costs. For users, self-installation and disassembly become easier, enhancing the product's user-friendliness.

[0035] The glass body has an arc-shaped cross-section, and the distance between adjacent glass body sidewalls is controlled between 0.5mm and 1mm. This design effectively controls light, reducing light leakage through the gaps and concentrating light propagation. Furthermore, when exposed to temperature changes, especially increases, the glass body expands due to thermal expansion; this pre-reserved gap provides space for this expansion, preventing cracking or deformation caused by mutual compression between the glass bodies. This ensures the light guide assembly operates stably and reliably under different temperature conditions.

[0036] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
