Description

Technical Field

[0001] The present invention relates to the technical field of lighting equipment, and in particular to an LED ceiling lamp with intelligent brightness adjustment and a control method. Background Art

[0002] LED ceiling lights are lighting equipment that uses light-emitting diodes (LEDs) as light sources. They are usually installed directly on the ceiling and are widely used in various indoor environments such as homes, offices, and shops. Compared with traditional fluorescent lamps or incandescent lamps, LED ceiling lights have the advantages of energy saving, high efficiency, long life, and environmental protection.

[0003] Related technologies can refer to the patent application with publication number CN117781233A, which discloses a ceiling lamp, including a snap-on assembly and a pressing assembly. The quick-release tray is provided with a snap-on portion and a key-in hole. The lamp body is detachably and rotatably arranged on the quick-release tray. The quick-release assembly is arranged on the lamp body. The button can slide relative to the lamp body. When the button abuts against the key-in hole, the button is in a pressed state. When the button is separated from the key-in hole, the button is in a floated state. The snap-on assembly includes a snap-on component, which can slide relative to the lamp body. When the snap-on component is in the snap-on state, the snap-on component and the snap-on portion snap-fit ​​to install the lamp body on the quick-release tray. When the snap-on component is in the separated state, the snap-on component is separated from the snap-on portion to remove the lamp body from the quick-release tray. When the button is in the floated state, the button pushes the snap-on component to slide and changes the snap-on component from the snap-on state to the separated state; this application can improve installation accuracy and installation convenience.

[0004] However, when the above disclosed technology needs to adjust the brightness for different usage scenarios, the dimming method is PWM dimming, that is, changing the voltage pulse width applied to the LED to control the average power, so as to achieve continuous brightness adjustment. In the process of brightness adjustment by PWM dimming method, the light usually flickers, which seriously affects the user's eye health and the user's experience. Therefore, there is an urgent need for an LED ceiling lamp with intelligent brightness adjustment and a control method to solve the above technical problems. Summary of the invention

[0005] In order to protect eye health and improve user experience, the present invention provides an LED ceiling lamp with intelligent brightness adjustment and a control method.

[0006] In a first aspect, the present invention provides an LED ceiling lamp with intelligent brightness adjustment, which adopts the following technical solution:

[0007] A LED ceiling lamp with intelligent brightness adjustment comprises a connecting plate, a mounting plate is connected to the bottom of the connecting plate, the mounting plate is horizontally arranged, a mounting groove is opened on the side of the mounting plate away from the connecting plate, an LED light board is installed in the mounting groove, a control groove is opened on the side of the mounting plate away from the connecting plate, a bidirectional screw is arranged in the control groove, two baffles for shielding the light source are arranged on both sides of the LED light board, the two baffles are relatively arranged on both sides of the LED light board, the two baffles are respectively threadedly connected to the two ends of the bidirectional screw, a driving motor is arranged in the mounting plate, the output shaft of the driving motor is coaxially fixedly connected with the bidirectional screw, the connecting plate is a hollow cavity, a threaded tube is arranged in the connecting plate, a threaded rod is arranged between the connecting plate and the mounting plate, one end of the threaded rod is rotatably connected to the mounting plate, and the other end is threadedly connected to the threaded tube in the connecting plate, and one end of the threaded rod close to the mounting plate extends into the mounting plate and is connected to the bidirectional screw through a bevel gear pair.

[0008] By adopting the above technical solution, when the brightness of the ceiling lamp needs to be changed, the staff starts the driving motor, and the driving motor drives the bidirectional screw to rotate, thereby driving the two baffles to move toward or away from each other, thereby changing the light-emitting area on the LED lamp board, thereby changing the overall brightness. The dimming method through physical blocking will not cause light flickering, which is beneficial to eye health and user experience. While the staff changes the brightness of the light source through the driving motor, the threaded rod will rotate synchronously in the threaded tube, thereby adjusting the height of the mounting plate to adjust the height of the light source. When the baffle blocks the light-emitting area, the illumination range of the light source is reduced. At this time, raising the height of the light source can restore its illumination range, avoiding changes in the light source range when the light source is adjusted, which is beneficial to ensuring the stability of the light source.

[0009] Optionally, a convex diffusion lens is mounted below the mounting plate via bolts.

[0010] By adopting the above technical solutions, light can be evenly dispersed in all directions, reducing the phenomenon of central hot spots and dark areas on the edges, providing a more consistent lighting effect. For applications that require large-area coverage, this feature helps ensure that every corner has sufficient brightness.

[0011] Optionally, a plurality of stabilizing rods are connected between the connecting plate and the mounting plate. The stabilizing rods are evenly arranged, one end of the stabilizing rod is fixedly connected to the mounting plate, and the other end extends into the connecting plate and is equipped with a limiting ring to prevent the mounting plate from falling off.

[0012] By adopting the above technical solution, the stabilizing rods are evenly distributed between the connecting plate and the mounting plate to form a stable supporting frame, which effectively reduces the lateral shaking or rotation of the mounting plate that may occur during the height adjustment process, especially for occasions where the light source needs to be kept absolutely stable, ensuring that the lighting effect is not affected by mechanical movement; the setting of the limit ring plays a double insurance role: on the one hand, it limits the maximum stroke of the mounting plate to prevent it from accidentally sliding out; on the other hand, even if the threaded connection fails, it can prevent the mounting plate from falling, thereby ensuring the safety of personnel and equipment below.

[0013] Optionally, the mounting groove of the mounting plate is also connected with two movable grooves, the two movable grooves are arranged opposite to each other, and two connecting rods are provided at the movable groove of the mounting plate, one end of the connecting rod is located at the movable groove and is provided with a safety ring to prevent the connecting rod from falling off, the safety ring is located at the movable groove of the mounting plate, and the end of the connecting rod away from the movable groove is passed through the LED light board, and the LED light board is movably connected to the mounting groove of the mounting plate, and two positioning plates are fixedly connected to the convex diffusion lens, and the two positioning plates are arranged corresponding to the two connecting rods. Before installing the convex diffusion lens, the connecting rod moves downward, the LED light board falls and detaches from the mounting groove, and the safety ring is clamped at the bottom end of the movable groove; after installing the convex diffusion lens, the connecting rod moves upward, the LED light board is located at the mounting groove, and the safety ring is located at the top of the movable groove.

[0014] By adopting the above technical solution, when the convex diffusion lens is not installed, the LED light board is located below the installation slot, which makes it convenient for users to replace or repair the LED light board; when the convex diffusion lens is installed, the positioning plate abuts the connecting rod, and during the installation process, the connecting rod moves upward, driving the LED light board to return to the installation slot, thereby resetting the equipment.

[0015] Optionally, an LED ceiling lamp with intelligent brightness adjustment also includes a PLC control panel, the driving motor is electrically connected to the PLC control panel, and the PLC control panel is installed on a wall indoors.

[0016] By adopting the above technical solution, when the brightness of the LED ceiling lamp needs to be changed, the staff inputs instructions on the PLC control panel to control the operation of the drive motor, thereby realizing the function of intelligent brightness adjustment, which is conducive to improving user experience.

[0017] In a second aspect, the present application provides a control method, comprising the following steps:

[0018] S1: When the indoor brightness needs to be controlled, the staff inputs instructions through the PLC control panel, and the drive motor works according to the instructions;

[0019] S2: The driving motor drives the bidirectional screw to rotate, and the bidirectional screw drives the two baffles to move toward or away from each other to change the number of light sources of the LED light board, thereby reducing or increasing the brightness of the light after being homogenized in the convex diffusion lens;

[0020] S3: When the driving motor is working, the threaded rod rotates synchronously, so that the mounting plate moves up or down as a whole to change the height of the light source, ensuring the consistency of the irradiation range of the light source after the brightness of the light source is changed.

[0021] In summary, the present invention includes at least one of the following beneficial technical effects:

[0022] 1. By setting the connection plate, mounting plate, LED light board, control slot, bidirectional screw and baffle, when the brightness of the ceiling light needs to be changed, the staff starts the drive motor, and the drive motor drives the bidirectional screw to rotate, thereby driving the two baffles to move towards or away from each other, thereby changing the light-emitting area on the LED light board, thereby changing the overall brightness. The way of dimming by physical shielding will not cause light stroboscopic phenomenon, which is beneficial to eye health and improves user experience;

[0023] 2. By setting the stabilizing rod and the limiting ring, the stabilizing rod is evenly distributed between the connecting plate and the mounting plate to form a stable support frame, which effectively reduces the lateral shaking or rotation of the mounting plate during the height adjustment process, especially for occasions where the light source needs to be kept absolutely stable, to ensure that the lighting effect is not affected by mechanical movement; the setting of the limiting ring plays a double insurance role: on the one hand, it limits the maximum travel of the mounting plate to prevent it from accidentally sliding out; on the other hand, even if the threaded connection fails, it can prevent the mounting plate from falling, ensuring the safety of personnel and equipment below;

[0024] 3. By setting a convex diffusion lens, the light can be evenly dispersed in all directions, reducing the phenomenon of central hot spots and edge dark areas, providing a more consistent lighting effect. For applications that require large area coverage, this feature helps ensure that every corner can get enough brightness. BRIEF DESCRIPTION OF THE DRAWINGS
