Abstract
Description
Technical Field
[0001] This utility model relates to the field of household lighting technology, specifically a ceiling light that can eliminate residual light. Background Technology
[0002] Ceiling lights are lighting fixtures installed on the ceiling inside a room. They are characterized by space saving, good decorative effect, and uniform light distribution. Currently, due to energy-saving needs, LED lamp beads are generally used as the light source. LED lamp beads have the characteristics of high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safety and environmental protection. LED ceiling lights can be dimmed and color-adjusted through a microcomputer built-in controller, producing soft, bright and colorful light. Current conventional products use aluminum substrates with LED beads mounted on an iron base. They are used with a wireless driver board and a corresponding remote control, allowing users to turn off the signal system in the driver board through the remote control. After the signal system is turned off, the power to the circuit is cut off through the driver board.
[0003] Currently, even after the signal control system of a ceiling light is turned off via remote control, the LED bulbs often remain dimly lit due to a residual current in the circuit. This phenomenon is usually caused by the design characteristics of the LED driver circuit. After the signal control system is disconnected via remote control, the entire circuit is not physically powered off, failing to immediately and completely eliminate the stored electrical energy within the ceiling light. This allows the LED bulbs to continue lighting up with an extremely weak glow. This residual current not only affects the complete extinguishing of the ceiling light when it is fully off, but may also consume unnecessary energy to some extent. Although this consumption is relatively small, it can accumulate over time and affect energy efficiency. Furthermore, for those with extremely high requirements for indoor lighting conditions, this dim state can be considered a visual disturbance or discomfort, significantly impacting sleep quality. Utility Model Content
[0004] To address the problem mentioned in the background art that residual current in current ceiling lights slightly illuminates the LED beads after they are turned off, the purpose of this invention is to provide a ceiling light that can eliminate residual light.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a ceiling light that can eliminate residual light, including a chassis, wherein a plurality of aluminum substrates, a drive board and wiring terminals are installed on the inner side of the chassis, the drive board and the wiring terminals are electrically connected by a connecting wire, and the drive board and the aluminum substrates are connected in series.
[0006] Each of the aluminum substrates is equipped with a number of LED beads, which are connected in parallel.
[0007] The chassis is also equipped with a residual light removal module, which includes a corresponding substrate and a capacitor. The substrate in the residual light removal module is connected in parallel with the aluminum substrate.
[0008] Preferably, the aluminum substrate is uniformly installed inside the chassis.
[0009] Preferably, the driver board is a wireless remote control module.
[0010] Preferably, the chassis is square.
[0011] Preferably, the chassis is circular.
[0012] Preferably, the aluminum substrates are arranged in a linear array.
[0013] Preferably, the lamp bead is an LED lamp bead.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. When this utility model is in use, the capacitor in the residual light removal module can absorb the residual current in the driver board and lamp board after the remote control turns off the light, blocking the excess current from flowing to the lamp beads, thereby fundamentally avoiding the residual light phenomenon that may occur after the light is turned off, providing users with a more refreshing light-off environment and effectively improving users' sleep quality.
[0016] 2. The residual light removal module designed in this utility model includes two capacitor modules. One end of each capacitor module is connected to the positive and negative wires of the lighting module constructed from an aluminum substrate, while the other end of each module is connected to the grounding system. This layout design aims to more effectively absorb the residual current inside the LED beads, thereby effectively preventing unnecessary residual light phenomena after the lamp is turned off, improving user comfort and energy efficiency management.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] As a first embodiment of this application, refer to Figure 1 and Figure 4 As shown in the figure, this embodiment provides a ceiling light that can eliminate residual light, including a circular base 1. Several aluminum substrates 2, drive boards 3 and wiring terminals 5 are installed on the inner side of the base 1. The aluminum substrates 2, drive boards 3 and wiring terminals 5 are all fixed to the base 1 by screws. The aluminum substrates 2 are evenly arranged and installed on the inner side of the base 1. A lampshade is also installed on one side of the base 1. The lampshade is not shown in the figure. In this embodiment, the surface of the lampshade has a frosted texture.
[0024] The driver board 3 is electrically connected to the terminal block 5 via a connecting wire 4. Specifically, the driver board 3 is connected in series with the aluminum substrate 2, but the aluminum substrates 2 are connected in parallel. When one aluminum substrate 2 is damaged, the LED beads 21 on the other aluminum substrates 2 can still emit light, further improving the durability of this embodiment. At the same time, several LED beads 21 are installed on each aluminum substrate 2, and the LED beads 21 are also connected in parallel. The LED beads 21 are LED beads. A residual light removal module 6 is also installed inside the chassis 1. The residual light removal module 6 includes a corresponding substrate and a capacitor. The substrate in the residual light removal module 6 is connected in parallel with the aluminum substrate 2. Specifically, the driver board 3 is a 2.4G wireless remote control driver board 3, which can control the start and stop of the LED beads 21 through a corresponding remote control. This technology is prior art and will not be described in detail again.
[0025] Specifically, the residual light removal module 6 designed in this utility model is a capacitor module. In this embodiment, the capacitor module is connected between the input / output terminal of the lamp board and the terminal 5. The capacitor module has three wires: a mains wire and a ground wire. The mains wire of the capacitor is connected to the input / output terminal of the aluminum substrate, and the ground wire of the capacitor is connected to the ground wire of the terminal 5. With this layout design, when the lamp driver board 3 is not working, the capacitor can absorb the weak residual current of the drive, so as not to let the residual current of the drive flow into the lamp bead 21 and cause residual light phenomenon.
[0026] It should be noted that the internal structure of the currently used ceiling lights is based on... Figure 3When the ceiling light is turned off, a portion of current remains on the driver board 3 and the aluminum substrate 2 on which the LED beads 21 are installed. This current slightly illuminates the LED beads 21, causing them to emit a faint light for a period of time. In the above embodiment, the capacitor in the residual light removal module 6 can absorb the residual current after the light is turned off, blocking the excess current from flowing to the LED beads 21. This fundamentally avoids the residual light phenomenon that may occur after the light is turned off. After the power is turned off, the LED beads 21 can be extinguished immediately and completely, completely eliminating the problem of residual light and providing users with a more refreshing lighting environment, effectively improving the user's sleep quality.
[0027] As a second embodiment (such as) Figure 2 As shown, the chassis 1 of this application can also be designed as a square structure, while the aluminum substrates 2 are neatly arranged in a linear array within the chassis 1. This design not only makes the light distribution of the ceiling light more uniform and softer, but also provides users with a higher quality and more comfortable lighting experience. In general, these innovative designs are all aimed at bringing users a more satisfactory and higher quality lighting solution.
[0028] It should be further clarified that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
