Description

Technical Field

[0001] This utility model relates to the field of household lighting technology, specifically a ceiling light that can avoid the generation of 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 can be 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 avoid the generation of residual light.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ceiling light that can avoid the generation of 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 chips connected in parallel. The aluminum substrates are also provided with a number of surface mount resistors, each of which is connected in series with a corresponding LED chip.

[0007] Preferably, each of the LED beads is connected in series with a corresponding surface mount resistor to form a lighting unit, and the lighting units are arranged in parallel.

[0008] Preferably, the driver board is a wireless remote control module.

[0009] Preferably, the chassis is square.

[0010] Preferably, the chassis is circular.

[0011] Preferably, the aluminum substrates are arranged in a linear array.

[0012] Preferably, the lamp bead is an LED lamp bead.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model connects a surface mount resistor in series with the circuit of each LED bead. The surface mount resistor can effectively prevent the remaining current in the driver board from being conducted to the inside of the LED bead and slightly lighting it after the light is turned off. This allows the LED bead to be turned off quickly and completely after the light is turned off, avoiding the generation of residual light, bringing a better experience to the user and improving the user's sleep quality.

[0015] 2. Before production, this invention allows for flexible selection of surface mount resistors of appropriate specifications based on the different power of the LED beads. This design makes the absorption process of residual current inside the LED beads more precise, effectively preventing the phenomenon of weak light emission (i.e., residual light) caused by residual current, thereby avoiding the interference that such unnecessary light may cause to sleep quality.

[0021] 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.

[0022] 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 avoid the generation of 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 with 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.

[0023] 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, each aluminum substrate 2 is equipped with several LED beads 21, which are also connected in parallel. The LED beads 21 are LED beads. The driver board 3 is a 2.4G wireless remote control driver board, which can control the start and stop of the LED beads 21 through the corresponding remote control. This technology is prior art and will not be elaborated further. The aluminum substrate 2 in this embodiment is also provided with several surface mount resistors 22, and each surface mount resistor 22 is connected in series with the corresponding LED bead 21.

[0024] It should be noted that each of the LED beads 21 is connected in series with a corresponding chip resistor 22 to form a lighting unit, and the lighting units are arranged in parallel. In the above embodiment, the chip resistor 22 can effectively block the residual current after the light is turned off from slightly illuminating the LED beads 21, so that the LED beads 21 can be quickly and completely extinguished after the light is turned off, eliminating the generation of residual light and bringing a better experience to the user.

[0025] 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 small amount of current remains on the driver board 3 and the aluminum substrate 2 on which the LED beads 21 are installed. This current will slightly light up the LED beads 21, causing them to emit a faint light for a period of time. By adding a surface-mount resistor 22 next to each LED bead 21 or along each series-parallel path, the remaining weak current can be prevented from flowing into the LED bead when the driver board 3 is not working. This avoids the residual light phenomenon that may occur after the light is turned off, completely eliminates the problem of residual light, provides users with a more refreshing lighting environment, and effectively improves users' sleep quality.

[0026] Furthermore, 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 aim to bring users a more satisfactory and higher quality lighting solution.

[0027] 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.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
