However, while existing flame-simulating lights may resemble flames in appearance, their light sources are mostly constantly on, unable to simulate the dynamic changes of a flame by adjusting the brightness. This results in a significant difference from the flickering and dancing of a real flame, making it difficult to meet users' needs for an immersive, highly realistic flame atmosphere. Summary of the Invention

[0033] Flame-simulating light bulbs are lighting fixtures that mimic the shape of flames to create a unique atmosphere in indoor and outdoor spaces. They are often used in restaurants, bars, courtyards, and other settings to simulate the leaping and flickering of flames, creating a warm, romantic, or vibrant ambiance.

[0034] However, existing flame-simulating decorative lights have significant technical flaws. On the one hand, the circuit design lacks effective voltage regulation and filtering mechanisms. When connected to external AC voltage, the lights are highly susceptible to current and voltage fluctuations, resulting in unstable light emission and an inability to provide users with a continuous and stable flame simulation effect. On the other hand, although existing flame-simulating lights mimic the shape of flames, the light source is mostly in a constant-on state. They cannot simulate the dynamic changes of flames by adjusting the brightness, resulting in a significant difference from the leaping and flickering scenes of real flames, making it difficult to meet users' needs for an immersive and highly realistic flame atmosphere.

[0035] Based on this, this application provides a flame-imitating light bulb and a flame-imitating decorative lamp to solve the aforementioned technical problems. The technical solutions provided by this application will be described in detail below.

[0036] Firstly, referring to Figure 1 and Figure 2 This application provides a flame-simulating light bulb, including: a lamp sleeve 410 and a lamp shade 420. The lamp shade 420 is disposed at one end of the lamp sleeve 410. A second circuit board 600 is provided inside the lamp sleeve 410 near the lamp shade 420. The second circuit board 600 includes a control module 610 and a flame lamp module 620. The flame lamp module 620 extends into the lamp shade 420. The input terminal of the control module 610 is used to connect to an external power supply unit, and the output terminal of the control module 610 is connected to the flame lamp module 620 to control the brightness state of the flame lamp module 620 to simulate the dynamic effect of a flame.

[0037] The second circuit board 600 is located near the lampshade 420 on the lamp cover 410, focusing on controlling the lighting effects. The external power supply unit transmits power via wires to the control module 610 of the second circuit board 600 inside the lamp cover 410. The control module 610, according to a preset program, precisely adjusts the brightness of the flame lamp module 620, thereby simulating the dynamic effects of flame flickering and dancing. The combination of the control module 610 and the flame lamp module 620 enables the control of light brightness, breaking the limitation of traditional flame lamps that are always on, realistically simulating the dynamic effects of flames, creating an immersive flame atmosphere, and meeting users' needs for highly realistic flame decorative lights.

[0038] Understandably, the flame lamp module 620 includes several LEDs arranged spirally around the inner wall of the lampshade 420. The control module U2 controls the brightness of each LED individually. The spiral arrangement of multiple LEDs around the inner wall of the lampshade 420 allows them to emit light from different angles and positions. The control module U2's individual control of each LED's brightness allows for different combinations of brightness variations, simulating the flickering and dancing effects of flames, making the simulated flame decorative lamps more realistic.

[0039] Understandably, the lampshade 420 has multiple evenly distributed buckles on its inner edge near the lamp sleeve 410, and the lamp sleeve 410 has multiple corresponding slots on its outer edge near the lampshade 420. Through the cooperation of the buckles and slots, the lampshade 420 and lamp sleeve 410 can be quickly and easily connected together. When the lamp needs maintenance, bulb replacement, or cleaning, the lampshade 420 can also be easily separated from the lamp sleeve 410, improving the convenience of lamp maintenance. Furthermore, the multiple evenly distributed buckles and slots engage with each other, providing a uniform tightening force in the circumferential direction, making the connection between the lampshade 420 and lamp sleeve 410 more secure.

[0040] Secondly, referring to Figure 1 and Figure 2 This application provides a flame-shaped decorative lamp, comprising: a base 100, a supporting main rod 200, an arc-shaped connecting rod 300, and a flame-shaped light bulb according to any embodiment of the first aspect. Specifically, the flame-shaped light bulb includes a lamp sleeve 410 and a lamp shade 420. The base 100 is provided with a first circuit board 500, which includes a filter module 510, a rectifier module 520, and a voltage regulator module 530 connected in sequence. The input terminal of the filter module 510 is used to connect to an external AC voltage. The supporting main rod 200 has a hollow structure, and one end of the supporting main rod 200 is connected to and communicates with the base 100. Multiple arc-shaped connecting rods 300 are provided, and one end of each is connected to the side wall or top of the supporting main rod 200. The rod 300 has a hollow structure and is connected to the supporting main rod 200; one end of the lamp sleeve 410 is connected to the other end of the arc-shaped connecting rod 300, and the lamp shade 420 is set at the other end of the lamp sleeve 410. The lamp sleeve 410 has a second circuit board 600 inside the end near the lamp shade 420. The second circuit board 600 includes a control module 610 and a flame lamp module 620. The flame lamp module 620 extends into the lamp shade 420. The input end of the control module 610 is connected to the output end of the voltage regulator module 530 through a wire passing through the lamp sleeve 410, the arc-shaped connecting rod 300 and the supporting main rod 200. The output end of the control module 610 is connected to the flame lamp module 620 to control the brightness state in the flame lamp module 620 to simulate the dynamic effect of a flame.

[0041] In the aforementioned flame-shaped decorative lamp, the filter module 510 of the first circuit board 500 inside the base 100 is first connected to an external AC voltage to filter out noise in the current. Subsequently, the rectifier module 520 converts the AC power to DC power, and the voltage regulator module 530 stabilizes the output voltage, providing a stable power supply for subsequent circuits. The stable voltage output by the voltage regulator module 530 is transmitted through wires to the control module 610 of the second circuit board 600 inside the lamp cover 410. The control module 610 precisely controls the brightness of the flame lamp module 620 according to a preset program, thereby simulating the dynamic effects of flame flickering and dancing. In this application, the first circuit board 500 is located inside the base 100 and is specifically responsible for the initial power supply processing; the second circuit board 600 is located in the lamp cover 410 near the lamp shade 420 and focuses on controlling the lighting effect. This effectively reduces the impact of external voltage fluctuations on the lamp, ensures that the flame lamp module 620 can obtain a stable power supply, solves the problem of unstable light emission, and improves the stability and reliability of the lamp's operation. In addition, the combination of control module 610 and flame lamp module 620 can adjust the brightness of the light, breaking the limitation of traditional flame lamps that are always on, realistically simulating the dynamic effect of flames, creating an immersive flame atmosphere, and meeting users' needs for highly realistic flame decorative lights.

[0042] Reference Figure 3 It is understood that the filter module 510 includes a first capacitor C1 and a first resistor R1. One end of the first capacitor C1 and the first resistor R1 are respectively connected to the first AC input terminal of the first circuit board 500, and the other end of the first capacitor C1 and the first resistor R1 are respectively connected to the first input terminal of the rectifier module 520. The second input terminal of the rectifier module 520 is connected to the second AC input terminal of the first circuit board 500. In one embodiment, the first AC input terminal of the first circuit board 500 is used to connect to the live wire in the power grid, and the second AC input terminal of the first circuit board 500 is used to connect to the neutral wire in the power grid. The first capacitor C1 and the first resistor R1 constitute an RC filter circuit to remove high-frequency noise in the AC voltage, which can effectively reduce the impact of these interference signals on subsequent circuits such as the rectifier module 520, the voltage regulator module 530, and the flame lamp module 620. After filtering, the power supply can be cleaner, improving the stability and reliability of the entire lighting system.

[0043] Continue to refer to Figure 3It can be understood that the filter module 510 includes a first diode D1, a second diode D2, a third diode D3, and a fourth diode D4. The anode of the second diode D2 and the cathode of the fourth diode D4 are connected to form the first input terminal of the rectifier module 520. The anode of the first diode D1 and the cathode of the third diode D3 are connected to form the second input terminal of the rectifier module 520. The cathodes of the first diode D1 and the second diode D2 are connected to form the positive output terminal of the rectifier module 520. The anodes of the third diode D3 and the fourth diode D4 are connected to form the negative output terminal of the rectifier module 520. The positive output terminal is connected to the input terminal of the voltage regulator module 530, and the negative output terminal is connected to the output terminal of the flame lamp module 620 and grounded. In the above technical features, the first diode D1, the second diode D2, the third diode D3, and the fourth diode D4 form a diode bridge rectifier circuit, realizing full-wave rectification so that regardless of whether the AC input voltage is in the positive or negative half-cycle, it can be converted into DC output.

[0044] Continue to refer to Figure 3 It is understood that the voltage regulator module 530 includes a Zener transistor U1. The input terminals of the Zener transistor U1 are connected to the positive output terminal of the rectifier module 520, the output terminal of the Zener transistor U1 is connected to the input terminal of the control module 610 via a wire, and the ground terminal of the Zener transistor U1 is connected to and grounded to the output terminal of the flame lamp module 620. When the DC voltage output by the rectifier module 520 is rectified, its voltage value may change with fluctuations in the input AC voltage or changes in the load. The input terminal of the Zener transistor U1 is connected to the positive output terminal of the rectifier module 520, receiving the rectified DC voltage. It automatically adjusts its conduction level according to changes in the output voltage. When the output voltage increases, the base-emitter voltage of the Zener transistor U1 changes accordingly, increasing the resistance between the collector and emitter of the transistor. This allows it to handle more voltage, reducing the voltage output to the control module 610 and maintaining its stability. Conversely, when the output voltage decreases, the resistance between the collector and emitter of the transistor decreases, allowing more voltage to pass through and ensuring a stable output voltage. The stable voltage output by the voltage regulator module 530 prevents the control module 610 from issuing incorrect control signals due to voltage fluctuations. This allows the flame lamp module 620 to more accurately simulate the dynamic changes of flames, such as flickering and dancing, improving the realism of the flame simulation.

[0045] Continue to refer to Figure 3It is understandable that the voltage regulator module 530 also includes a protection diode D5. The anode of the protection diode D5 is connected to the negative output terminal of the rectifier module 520, and the cathode of the protection diode D5 is connected to the positive output terminal of the rectifier module 520. During normal operation, the rectifier module 520 converts AC to DC, and its positive output terminal potential is higher than its negative output terminal potential. At this time, the protection diode D5 is in a reverse bias state, meaning almost no current flows through it, so it does not affect the normal operation of the rectifier module 520 and subsequent circuits. However, when an abnormal situation occurs in the circuit, such as reversed power supply polarity or a reverse voltage at the output terminal of the rectifier module 520, the protection diode D5 immediately enters a forward bias state. Since the diode has very low resistance when forward biased, it provides a low-impedance path for reverse current. By avoiding damage to components from reverse voltage, the protection diode D5 significantly improves the reliability and stability of the entire flame-shaped decorative lighting circuit. This reduces lighting fixture malfunctions and damage caused by reverse voltage problems, lowering maintenance costs and user risks.

[0046] Continue to refer to Figure 3 Understandably, the voltage regulator module 530 also includes a second capacitor C2. One end of the second capacitor C2 is connected to the output terminal of the Zener transistor U1, and the other end of the second capacitor C2 is connected to the ground terminal of the Zener transistor U1. Although the Zener transistor U1 has already regulated the rectified voltage, there may still be some minor ripple or fluctuations in the output voltage. By adding the second capacitor C2, these ripples and fluctuations can be effectively reduced, making the voltage output to the control module 610 more stable. This improves the stability and accuracy of the control module 610's operation, ensuring that the flame lamp module 620 can more accurately simulate flame effects.

[0047] Reference Figure 1 It is understandable that the several arc-shaped connecting rods 300 set on the side wall of the supporting main rod 200 are symmetrically distributed relative to the supporting main rod 200. On the one hand, the symmetrically distributed arc-shaped connecting rods 300 can provide support and tension to the supporting main rod 200 from multiple directions, making the entire structure more stable. On the other hand, the symmetrical distribution conforms to people's aesthetic habits, enhances the overall aesthetics of the lamp, and makes it more compatible with various decorative styles, achieving a better decorative effect.

[0048] Understandably, a reinforcing rib structure is provided at the connection point between the arc-shaped connecting rod 300 and the supporting main rod 200. Due to uneven force transmission and distribution at the connection point, stress concentration is prone to occur. The reinforcing rib structure can disperse the concentrated stress over a larger area, reducing the local stress level at the connection point, decreasing the risk of material fatigue and damage caused by stress concentration, and extending the lifespan of the lighting fixture.

[0049] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
