Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a novel ceiling light. Background Technology

[0002] A ceiling light is a type of lighting fixture that is installed flush against the ceiling, hence its name. The light source for ceiling lights can be a regular incandescent bulb, fluorescent lamp, high-intensity discharge lamp, halogen lamp, or LED, among others. The most popular type of ceiling light on the market is the LED ceiling light, commonly used in homes, offices, entertainment venues, and various other spaces as the main indoor lighting.

[0003] With the advancement of lighting technology, the functionality of ceiling lights has also developed. The authorized Chinese patent, number "201921395011.9" and titled "Ceiling Light Base and Ceiling Light," states that "the ceiling light base and ceiling light provided by this utility model embodiment allow users to choose to install the ceiling light directly on the ceiling or on a fireproof box, thereby improving the convenience of using the ceiling light." As can be seen above, although the patent achieves the described technical effects, due to structural limitations, like other technologies in the field, it also has the following technical drawbacks. Firstly, the transparent lampshade at the lower end is fixed to the lower end of the lamp holder body using nuts and fixing rings. Therefore, when the bulb or other components inside the lamp holder are damaged, or when excessive dust enters and the lampshade needs cleaning, the user needs to unscrew the bolts and fixing rings securing the lampshade. This process requires the user to reverse the process to reinstall the lampshade, making the disassembly and assembly relatively cumbersome and inconvenient for the user. Secondly, when the power supply fails at night or the user turns off the main power switch, the inability to provide emergency lighting will have an adverse effect on users in the lighting area who are unable to leave the site. Utility Model Content

[0004] To overcome the shortcomings of existing ceiling lights due to structural limitations, as described in the background art, this utility model provides a new type of ceiling light that uses a magnetic method to fix a transparent lampshade to the ceiling light body, making it convenient for users to install and remove the lampshade. It can also automatically connect the power supply of emergency lamp beads when the 220V AC power supply fails or when the user actively turns off the main power, which brings convenience to the user when leaving the scene and prevents the user from bumping into other objects in the room due to poor lighting during a sudden power outage.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A novel ceiling light includes a ceiling light body, a power module, a battery, and a power outage detection circuit. An iron ring is fixedly installed on the upper outer side of the transparent lampshade of the ceiling light body, and a magnetic ring is fixedly installed on the lower outer side of the lamp holder body of the ceiling light body. The lampshade is attracted to the lower end of the lamp holder body by the iron ring and the magnetic ring. An operating block is fixedly installed on the lower end of the transparent lampshade. The power module, battery, and power outage detection circuit are installed in a component box inside the ceiling light body. The power input terminal of the power module and the control power input terminal of the power outage detection circuit are connected in series via a power switch and to the two poles of an AC power supply via wires. The power output terminal of the power module is connected to the two poles of the battery and the power input terminal of the power outage detection circuit via wires.

[0006] Furthermore, the power outage detection circuit includes a trigger sub-circuit and an output sub-circuit. The signal output terminal of the trigger sub-circuit and the signal input terminal of the output sub-circuit are connected by a wire. The trigger sub-circuit includes a resistor, an optocoupler, and a diode connected by a wire. The emitter of the phototransistor inside the optocoupler is connected to one end of the first resistor, and one end of the second resistor is connected to the positive terminal of the light-emitting diode inside the optocoupler. The negative terminal of the light-emitting diode is connected to the positive terminal of the diode.

[0007] Furthermore, the output sub-circuit includes a relay, a transistor, a resistor, an emergency LED, and a time relay module connected by wires. The power input terminal of the emergency LED is connected to the two normally open contacts of the relay. The positive control power input terminal of the relay is connected to the positive power input terminal and the positive trigger signal input terminal of the time relay module. One end of the resistor is connected, and the other end of the resistor is connected to the collector of the first transistor and the base of the second transistor. The emitters of the two transistors are connected to the negative power input terminal of the time relay module, the negative power input terminal of the relay, and the negative control power input terminal. The collector of the second transistor is connected to the negative trigger signal input terminal of the time relay module. The power output terminal of the time relay module is connected to the positive power input terminal of the relay.

[0008] Furthermore, the outer diameter of the lampshade is the same as the outer diameter of the lower end of the lamp holder body.

[0009] Compared with the prior art, the advantages of this utility model are: (1) Based on the ceiling lamp body, the transparent lampshade is fixed by magnetic attraction, which makes it convenient for users to disassemble and install the lampshade, clean the lampshade and replace the bulb or other parts in the lamp holder body; (2) Under the action of the power outage detection circuit, when the 220V AC power supply fails or when the user turns off the main power switch, the power supply of the emergency lamp beads can be automatically connected, which makes it convenient for users to leave the scene and prevents the user from being injured by collision with other objects in the room due to poor lighting at the scene of a sudden power outage.

[0014] Figure 1 , 2 As shown in Figures 1 and 3, a novel ceiling light includes a ceiling light body 1, a power module E1, a battery G, and a power outage detection circuit 2. A hollow annular iron ring 102 is glued to the upper outer side of the transparent lampshade 101 of the ceiling light body. A permanent hollow annular magnet ring 104 is glued to the lower outer side of the lamp holder body 103 of the ceiling light body. The lampshade 101 is attracted to the lower end of the lamp holder body 103 by the iron ring 102 and the magnet ring 104. An operating block 105 is glued to the left and right sides of the lower end of the transparent lampshade 101 (to facilitate the user to hold the operating block 105 with both hands to remove or install the transparent lampshade 101). The power module E1, the battery G, and the power outage detection circuit 2 are installed on a circuit board inside the component box 3 within the ceiling light body.

[0015] Figure 1 , 2As shown in Figure 3, the power outage detection circuit includes a trigger sub-circuit and an output sub-circuit. The other end of the resistor R3 at the signal output terminal of the trigger sub-circuit is connected to the base of the transistor VT3 at the signal input terminal of the output sub-circuit via a wire. The trigger sub-circuit includes resistors R2 and R3, optocoupler E4, and diode VD1 connected via wires. The emitter of the phototransistor inside optocoupler E4 is connected to one end of the first resistor R3. One end of the second resistor R2 is connected to the positive terminal of the light-emitting diode inside optocoupler E4. The negative terminal of the light-emitting diode is connected to the positive terminal of diode VD1. The output sub-circuit includes relay J1, transistors VT2 and VT3, resistor R4, emergency lamp H, and time relay module E3, all connected by wires. The power input terminal of emergency lamp H is connected to the two normally open contacts of relay J1. The positive control power input terminal of relay J1 is connected to pin 1 of the positive power input terminal and pin 3 of the positive trigger signal input terminal of time relay module E3, and one end of resistor R4 is connected. The other end of resistor R4 is connected to the collector of the first transistor VT3 and the base of the second transistor VT2. The emitters of transistors VT2 and VT3 are connected to pin 2 of the negative power input terminal of time relay module E3, the negative power input terminal of relay J1, and the negative control power input terminal. The collector of the second transistor VT2 is connected to pin 4 of the negative trigger signal input terminal of time relay module E3. Pin 9 of the power output terminal of time relay module E3 is connected to the positive power input terminal of relay J1. The outer diameter of lamp cover 101 is the same as the lower outer diameter of lamp holder body 103.

[0016] Figure 1 , 2 As shown in Figure 3, the power input terminals 1 and 2 of the power module E1, the other end of the resistor R2 at the control power input terminal of the power failure detection circuit, the negative terminal of diode VD1, and the bulb H1 of the ceiling light body 1 are connected in series with the power switch S (panel power switch) and the two terminals of the AC 220V power supply via wires. The power output terminals 3 and 4 of the power module E1 are connected to the two terminals of the battery G, the positive terminal of the relay J1 at the power failure detection circuit, the collector of the phototransistor built into the optocoupler, and the emitter of the transistor VT3 via wires. Figure 3As shown, power module E1 is a finished AC 220V to DC 12V switching power supply module (standby current is only about 10mA); battery G is a 12V / 5Ah lithium battery; resistors R2, R3, and R4 have resistance values ​​of 100K, 1K, and 200K respectively; transistors VT2 and VT3 are NPN transistors of model 9013; emergency light H is a 10W 12V incandescent bulb (LED bulbs can also be used), and the distance between emergency light H and bulb H1 is located in the inner center of the lamp holder; relay J1 is DC 12V; optocoupler E4 is 4N25 (standby current is only about 5mA); diode VD1 is 1N4007; time relay module... Block E3 is a YYC-2S time controller module. The E3 time controller module has two power input terminals (pins 1 and 2), two trigger signal input terminals (pins 3 and 4), a setting button (pin 5), an emergency stop button (pin 6), a time increment button (pin 7), a time decrement button (pin 8), and a normally open power output terminal (pin 9). After powering on, the technician presses the setting button and operates the time increment and decrement buttons to set the normally open power output terminal to output positive power for the desired time period. After the set time period, the normally open power output terminal stops outputting power. Once the time is set, the time relay module starts timing after each trigger signal input to the two trigger signal input terminals. All components in this invention are mature products, and the working principles of each component will not be described in detail here. The standby current of this invention is less than 30mA, and the power consumption is extremely low, so the additional power consumption is negligible.

[0017] Figure 1 , 2 As shown in Figure 3, this new invention is based on the ceiling light body 1 (whose working principle is a mature existing technology, which will not be described in detail here). A transparent lampshade 101 is fixed by magnetic attraction, which facilitates the user's disassembly and assembly of the lampshade 101, cleaning of the lampshade 101, and replacement of the bulb H1 or other components inside the lamp holder body. (Specifically, the user can pull down the lampshade 101 with both hands via the operating block 105, separating the lampshade 101 from the lamp holder body 103, allowing for cleaning or replacement of other components; subsequently, after the lampshade 101 and lamp holder body 103 are attracted together, due to the strong attraction between the permanent magnet 104 and the steel material 102, the lampshade 101 will not fall under gravity). After the 220V AC power enters the power input terminal of the power module E1, pins 3 and 4 of the power module E1 output a stable 12V DC power supply to the battery G (the battery G is normally floating-charged to ensure that the relevant circuits can operate after a power outage) and the power input terminal of the power outage detection circuit.

[0018] Figure 1 , 2As shown in Figure 3, when the power switch S is turned on, if the mains power is not interrupted (at this moment, bulb H1 is energized and illuminates), the two poles of the 220V AC power supply will respectively enter the other end of resistor R2 and the negative terminal of diode VD1. The 220V AC power supply forms a circuit through resistor R2 (voltage reduction and current limiting), the LED built into optocoupler E4, and diode VD1 (diode half-wave rectification). The LED built into optocoupler E4 is energized and illuminates, and the phototransistor built into optocoupler E4 conducts. The emitter of the phototransistor built into optocoupler E4 outputs a high level, which is reduced and current limited by resistor R3 and enters the base of transistor VT3. Transistor VT3 conducts, and the collector outputs a low level, which enters the base of transistor VT2. Transistor VT2 is cut off without a suitable forward bias voltage, and relay J1 will not be energized and engaged (pin 4 of time relay module E3 will not be energized). Thus, the emergency lamp H will not be energized and illuminate. If the mains power fails or the user actively turns off the power switch S, there is no 220V AC power supply. The two poles of the power supply enter the other end of resistor R2 and the negative terminal of diode VD1. The LED built into optocoupler E4 stops emitting light, the phototransistor built into optocoupler E4 is cut off, and the emitter of the phototransistor built into optocoupler E4 stops outputting a high level to the base of transistor VT3. The base of transistor VT2 obtains a suitable forward bias voltage through resistor R4 to reduce the voltage and limit the current, and conducts its collector to output a low level to pin 4 of time relay module E3. Pin 9 of time relay module E3 outputs a high level for a period of time (e.g., 2 minutes) to the positive power input terminal of relay J1. Relay J1 will be energized and close the control power input terminal and the normally open contact terminal. In this way, the emergency light bead H will be energized and illuminate for 2 minutes. As described above, when the 220V AC power supply fails or the user actively turns off the power switch S, the emergency light bulb can be automatically powered on, which makes it convenient for the user to leave the scene in poor lighting conditions and prevents the user from being injured by bumping into other objects in the room due to poor lighting conditions during a sudden power outage.
