Description

Technical Field

[0001] The present invention relates to the technical field of adjustable lighting devices, and in particular to a highly parallel dynamic adjustable lighting device. Background Art

[0002] In parallel illumination experiments, ensuring that the experimental device receives uniform and quantifiable illumination is a key prerequisite for ensuring the accuracy and repeatability of experimental results. However, traditional illumination systems generally have the following technical bottlenecks:

[0003] Traditional lighting systems often use top or side illumination. However, due to the spatial relationship between the light source and the shake flask, the light intensity decays nonlinearly with distance. For example, top illumination can easily lead to vertical light intensity gradients within the shake flask, while side illumination creates horizontal shadows due to differences in the density of the shake flasks.

[0004] Existing light source systems often rely on a single power source or group control mode, making it difficult to independently adjust light intensity at the individual shake flask or module level. When experiments require strictly consistent illumination across multiple parallel units, traditional devices require repeated manual calibration or mechanical shutter adjustment, which is complex and has limited accuracy. Furthermore, light source aging or voltage fluctuations can further reduce light intensity stability, and the lack of a real-time feedback adjustment mechanism makes it difficult to maintain illumination parallelism over the long term.

[0005] Traditional parallel illumination experimental setups often utilize multi-light source arrays or mechanical dimming structures, such as complex optical reflector systems, fiber-optic light guide systems, or angle-adjustable LED light panels to achieve light distribution control. Such designs require the integration of numerous optical components (such as lenses, filters, and diffusers) and mechanical transmission components (such as stepper motor-driven shading plates), resulting in bulky systems and high coupling between components. Furthermore, power distribution for multi-light source arrays typically utilizes a centralized drive solution, requiring independent dimming via multi-channel power amplifiers, further complicating circuit design. Summary of the Invention

[0006] The main purpose of the present invention is to provide a highly parallel dynamically adjustable lighting device that can effectively solve the problems in the background technology.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] A highly parallel dynamically adjustable lighting device comprises a shaking bottle, a shading plate, a lamp bead board, and a multi-channel independently controlled power supply. The shading plate is provided at the lower end of the shaking bottle, and the shading plate covers the top of the lamp bead board. Wires are provided on the side of the lamp bead board to connect to the multi-channel independently controlled power supply.

[0009] The multi-channel independent control power supply can be connected to multiple lamp bead boards, each of which can independently control the size of the voltage input. The multi-channel independent control power supply can be implemented by physical buttons, PLC or connection APP programming, and the multi-channel independent control power supply controls the lamp bead board to emit a certain amount of light;

[0010] The upper end surface of the light shielding plate is provided with a convex lens structure when the shaking bottle is placed, and the convex lens structure converges the light incident from below, and the outer ring of the convex lens structure is provided with a shaking bottle stabilizing ring, and the inner side surface of the shaking bottle stabilizing ring is set as an arc surface, and the inner side surface of the shaking bottle stabilizing ring is a frosted surface. The upper end surface of the light shielding plate is provided with a convex lens structure when the shaking bottle is placed, and the convex lens structure converges the light incident from below, and the outer ring of the convex lens structure is provided with a shaking bottle stabilizing ring. Except for the convex lens structure, other areas of the light shielding plate are subjected to light shading treatment to reduce the influence of stray light.

[0011] Preferably, the shaking bottle includes a light-shielding shell and a light-transmitting bottle bottom. The light-shielding shell can be realized by using light-proof glass, coating with opaque pigments, or wrapping with other materials. The constrained light emitted by the lamp bead board only shines into the shaking bottle from a quantitative area of ​​the light-transmitting bottle bottom.

[0012] A method for using a highly parallel dynamically adjustable lighting device, comprising the following steps:

[0013] S1: Device preparation and connection: Place the custom shake bottle on the light shield, ensuring the light shielding shell is intact and the bottom of the transparent bottle is facing down and aligned with the lamp bead board; check whether the light shield completely covers the surface of the lamp bead board to ensure there are no gaps or foreign objects blocking it; connect the lamp bead board to the multi-channel independent control power supply through wires, and confirm that the power interface is secure and there is no risk of short circuit;

[0014] S2: Initialization of illumination parameters: According to experimental requirements, select the control mode through multiple independent control power supplies: (i) Physical button mode: Manually adjust the voltage knob of each module to preset the initial light intensity value; (ii) PLC mode: Input the light intensity gradient parameters through the programming interface and set the dynamic change curve; (iii) APP mode: Connect to a mobile device and select a preset lighting scheme or customize the brightness of the lamp bead partitions through the graphical interface; one or more of the three adjustment modes can be selected;

[0015] For the lamp bead board module, the actual output value of the light intensity of the selected module inside the shaking bottle is adjusted through power calibration to adjust the light intensity output of each module to be highly consistent;

[0016] S3: Shake flask installation and light shielding verification: inject the sample to be cultured into the shake flask, align the bottom of the shake flask with the convex lens structure area of ​​the light shielding plate, and use the curved surface structure of the shake flask stabilizing ring to center it, so that the transparent bottom of the flask and the lamp bead plate maintain a distance of 2-5mm;

[0017] Perform light shielding test: Turn off the experimental environment light source and use a light intensity meter to measure the light leakage value of the light-shielding shell on the side of the shake flask; confirm that the light signal is only present in the transparent bottom area of ​​the flask, and eliminate the interference of side scattered light;

[0018] S4: Start the illumination program: The lamp bead board is triggered to emit light through multiple independent control power supplies. The light is evenly transmitted to the bottom of the shake bottle through the light shielding plate, forming a parallel light beam. Each lamp bead board is an independent lamp bead module. In the process of allocating the illumination area to mark the transparent bottle; the lamp bead board in the non-corresponding area is turned off according to the quantitative illumination area of ​​the transparent bottle. The light intensity output of the selected module is calibrated by the multiple independent control power supplies;

[0019] S5: After the experiment, turn off the multiple independent control power supplies, disconnect the wires, and put the equipment away.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The modular power supply of this invention features adjustable voltage, and a quantitative bottom area transmits light, allowing for quantitative light input. This facilitates the measurement of illumination values ​​at each point, and the light is then focused through the shading plate to achieve high parallelism. Furthermore, the invention utilizes a light-shielding housing to ensure that this highly parallel illumination is not affected by extraneous stray light.

[0022] The structure of the invention consists of a shaking bottle, a light shielding plate, a lamp bead board, a multi-channel independent control power supply and wires. The structure is simple and can ensure the parallelism and purity of the light. It has a wide range of applications and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
