Traditional flame lamps' control chips have high requirements for power supply stability; using unregulated mains power directly can lead to flickering light and uneven brightness. Therefore, existing flame lamps are generally powered by DC power and require an external power adapter to connect to mains power. The separate design of the power adapter and the flame lamp makes it difficult for flame lamps to directly replace traditional bulbs, failing to meet users' needs for immediate installation and use.

[0044] The present application will now be described in detail with reference to the accompanying drawings.

[0045] To solve the above technical problems, combined with Figure 1 , Figure 2 and Figure 7 As shown in the figure, this application embodiment provides a flame lamp, including a lamp body assembly 1 and a light source assembly 2. The lamp body assembly 1 includes a lamp head 11 and a light-transmitting lamp cover 12. After assembly, the lamp head 11 and the lamp cover 12 have a receiving cavity 13. The lamp head 11 can be set as a lamp head commonly used in bulb lamps, such as screw-in lamp heads E27, E14, E12, E40, B22, etc., or bayonet lamp heads GU10, etc. The lamp head 11 can be directly mounted on the lamp holder of a bulb lamp and connected to the mains power. The lamp cover 12 can be set as a bulb-shaped lamp cover 12. The light source assembly 2 is built into the receiving cavity 13, and the light source assembly 2 includes a power control structure 21 and a light-emitting structure 22. The power control structure 21 includes a power module 211. Terminals are provided on the lamp holder 11. The power module 211 includes an input terminal and an output terminal. The input terminal is electrically connected to the terminals on the lamp holder 11, and the output terminal is electrically connected to the light-emitting structure 22. The power module 211 can convert AC power to DC power and then step it down before outputting it to the light-emitting structure 22, thus powering the light-emitting structure 22. The light-emitting structure 22 emits light through the lamp cover 12, and its on / off changes according to a set sequence can simulate the effect of a real flame.

[0046] In one embodiment of this application, combined with Figure 7 , Figure 8 and Figure 9 As shown, the power module 211 includes a rectifier bridge 2111, a high-voltage filter circuit 2112, a step-down management chip 2113, and at least one low-voltage filter circuit 2114.

[0047] The rectifier bridge 2111 is a bridge structure composed of four diodes. During the positive and negative half-cycles of the AC current, the diode combination inside the rectifier bridge 2111 conducts, allowing current to flow in one direction and outputting pulsating DC current. The rectifier bridge 2111 includes two input pins, a positive output pin, and a negative output pin. The two input pins are electrically connected to the two terminals of the lamp holder, allowing access to 110V-250V AC power. The positive output pin is electrically connected to the high-voltage filter circuit 2112, and the negative output pin is grounded.

[0048] The high-voltage filter circuit 2112 includes an electrolytic capacitor 21121. The high-voltage filter circuit 2112 filters the pulsating DC output of the rectifier bridge 2111, smoothing the voltage waveform, reducing the voltage ripple coefficient, and providing a relatively stable DC voltage input for the subsequent step-down management chip 2113. The high-voltage filter circuit 2112 includes a positive pin and a negative pin. The positive pin is connected to the positive output pin of the rectifier bridge 2111, and the negative pin is grounded.

[0049] The step-down management chip 2113 steps down the DC voltage output from the high-voltage filter circuit 2112 to the required lower DC voltage, such as 3-5V. The step-down management chip 2113 includes an input pin, a positive output pin, a negative output pin, and a ground pin. The input pin is electrically connected to the positive pin of the rectifier bridge 2111, the positive and negative output pins are electrically connected to the low-voltage filter circuit 2114, and the ground pin is grounded.

[0050] The low-voltage filter circuit 2114, composed of a small-capacity capacitor 21141, further filters the DC voltage output by the buck management chip 2113, removing residual high-frequency noise and ripple to provide a clean and stable DC power supply for the subsequent light-emitting structure 22. The low-voltage filter circuit 2114 is electrically connected to the positive and negative output pins of the buck management chip 2113. One or more low-voltage filter circuits 2114 can be used, with multiple circuits sequentially connected between the buck management chip 2113 and the light-emitting structure 22.

[0051] In one embodiment of this application, combined with Figure 3 , Figure 7 and Figure 9 As shown, the light-emitting structure 22 includes a control chip 221 and light-emitting elements 222. The control chip 221 is electrically connected to the power module 211 and the last low-voltage filter circuit 2114. The control chip 221 includes at least one signal output pin 2211, and the light-emitting element 222 includes at least one segment of light-emitting unit 2221. The number of signal output pins 2211 is the same as the number of light-emitting units 2221. At least one signal output pin 2211 is connected to at least one light-emitting unit 2221. The control chip 221 outputs a level signal according to a set timing sequence, thereby controlling the multiple LEDs 22211 in each segment of light-emitting unit 2221 to change their brightness.

[0052] In one embodiment of this application, combined with Figure 3 , Figure 4 and Figure 9As shown, the multiple light-emitting units 2221 are arranged in strips and extend along the length of the lampshade 12, thereby ensuring that the light from the multiple light-emitting units 2221 is distributed throughout the entire lampshade 12. The outer surface of each of the multiple light-emitting units 2221 is coated with a light-transmitting coating 2228, which effectively scatters light, reduces the graininess of the light-emitting elements 222, and makes the light more uniform. Each light-emitting unit 2221 simulates a portion of a real flame, including different areas such as the root, middle, and top of the flame. By adjusting the brightness and color of each light-emitting unit 2221, a richer and more diverse range of flame effects can be created.

[0053] The light-emitting units 2221 are vertically arranged into six segments according to the burning direction of a real flame. The first segment 2222 and the second segment 2223 do not light up or turn off simultaneously. Both segments exhibit a cycle of brightness from bright to dim and then to dim, and vice versa. Within a preset time period, such as 10 seconds, the bright time of the first segment 2222 is greater than that of the second segment 2223, thus enhancing the natural characteristic of the continuous flickering at the base of the flame. The third to sixth segments 2227 simulate the middle and top of the flame. Within a preset time period, such as 10 seconds, the bright time of these segments gradually decreases, with a cyclical brightness variation. The first cycle involves a sequential decrease in brightness from the third light-emitting unit 2224 to the sixth light-emitting unit 2227, resulting in brightness decay. The second cycle maintains the brightness of the third, fourth, and sixth light-emitting units 2224, 2225, and 2227, while the brightness of the fifth light-emitting unit 2226 increases to simulate the dynamic effect of a flame suddenly leaping upwards. The third cycle decreases the brightness of the third, fourth, and fifth light-emitting units 2224, 2225, and 2226, while the brightness of the sixth light-emitting unit 2227 increases, creating the effect of the flame leaping upwards from the top. Subsequent cycles four through ten use random fluctuations in brightness values ​​(e.g., ±10%) and periodic resets to prevent the effect from becoming mechanically repetitive and enhance the natural randomness of the flame. It is understood that the coordination between multiple light-emitting units 2221 is not limited to the above methods; any combination that can create a flame effect will suffice, and will not be elaborated further here.

[0054] In one embodiment of this application, combined with Figure 2 and Figure 3As shown, the light-emitting structure 22 also includes a first circuit board 224, and a control chip 221 is disposed on one side of the first circuit board 224. The sheet-like first circuit board 224 is vertically disposed in the receiving cavity 13, and the light-emitting element 222 is vertically disposed on the top of the first circuit board 224. The vertical layout of the first circuit board 224 and the light-emitting element 222 makes full use of the space of the receiving cavity 13, which helps to reduce the overall size of the flame lamp.

[0055] In one embodiment of this application, combined with Figure 2 and Figure 4 As shown, the power control structure 21 also includes a second circuit board 212. Each electronic component in the power module 211 is mounted on the second circuit board 212. The sheet-like second circuit board 212 is vertically housed in the lamp holder 11. The second circuit board 212 is double-sided to facilitate the double-sided distribution of electronic components.

[0056] In one embodiment of this application, combined with Figure 2 and Figure 5 As shown, the lamp holder 11 includes a head 111 and a bayonet portion 112 extending outward from the head 111. Both the head 111 and the bayonet portion 112 are approximately cylindrical. The bayonet portion 112 is open, and its inner diameter is larger than that of the head 111. The second circuit board 212 is a vertically arranged sheet structure, including a first segment 2121 and a second segment 2122. The first segment 2121 and the second segment 2122 are integrally formed, with the width of the first segment 2121 being greater than the width of the second segment 2122. The first segment 2121 fully utilizes the relatively spacious space of the bayonet portion 112, while the second segment 2122 adapts to the more compact internal space of the head 111. Smaller electronic components mounted on the first circuit board 224 are located on the second segment 2122, and larger components are located on the first segment 2121. The second circuit board 212 can be shielded by the lamp head 11 to prevent it from shining through the lamp cover 12 and affecting the aesthetics of the flame lamp. Furthermore, the second circuit board 212's adaptation to the lamp head 11's top-wide, bottom-narrow structure facilitates installation and allows for the placement of more electronic components. In addition, the second circuit board 212 ensures that the light-emitting element 222 is positioned in the center of the lamp cover 12, preventing it from shifting. This ensures that the light from the light-emitting element 222 has a roughly uniform brightness when viewed from all angles of the lamp cover 12.

[0057] In one embodiment of this application, combined with Figure 5 and Figure 6As shown, the lampshade 12 includes an interface portion 121 and a cover portion 122. The cover portion 122 is bulb-shaped. The interface portion 121 and the cover portion 122 are integrally formed. The interface portion 121 is cylindrical and adapted to the bayonet portion 112. The interface portion 121 is located inside the bayonet portion 112 and between the bayonet portion 112 and the first segment 2121 of the second circuit board 212. The inner diameter of the interface portion 121 is adapted to the width of the first segment 2121. That is, the width of the first segment 2121 is set so that it can be clamped at least partially by the interface portion 121, making it difficult for the second circuit board 212 to shift. Two snap-fit ​​grooves 1211 are recessed inside the interface portion 121. The two sides of the first segment 2121 are respectively snapped into the two snap-fit ​​grooves 1211, thereby enabling the positioning of the second circuit board 212.

[0058] In one embodiment of this application, combined with Figure 5 and Figure 6 As shown, the cover portion 122 includes an inner layer 1221 and an outer layer 1222. The outer layer 1222 is shaped like a bulb and can scatter the light from the light-emitting element 222 over a wide angle. The inner layer 1221 forms a cone-shaped receiving cavity 1223. The width of the first circuit board 224 is greater than the width of the light-emitting element 222. The cone-shaped receiving cavity 1223 can adapt to accommodate the combined shape of the first circuit board 224 and the light-emitting element 222, and can prevent the first circuit board 224 and the light-emitting element 222 from shifting to a certain extent. The lampshade 12 can be a blow-molded or injection-molded shell.

[0059] In one embodiment of this application, combined with Figure 5 As shown, the lampshade 12 is either fully transparent or semi-transparent. The second circuit board 212 is directly housed in the lamp head 11, which is opaque, thus concealing the second circuit board 212. The first circuit board 224 is vertically mounted on top of the second circuit board 212. The first circuit board 224 is relatively small, only needing to provide a mounting position for the control chip 221. Therefore, the first circuit board 224 being exposed through the lampshade 12 does not affect the aesthetics of the flame lamp.

[0060] In one embodiment of this application, combined with Figure 1 As shown, preferably, the lamp holder 11 adopts a standardized screw-in design, specifically configured as either E12 or E14. The E12 lamp holder has a small screw-in diameter of 12 mm, suitable for compact lighting fixtures or specific regional markets such as the United States and Japan. The E14 lamp holder has a medium-sized screw-in diameter of 14 mm, widely used in decorative lighting fixtures and household lighting appliances in European and Asian markets. Both E12 and E14 lamp holders are universal, thus improving the flame lamp's ready-to-use characteristic.

[0061] In one embodiment of this application, combined with Figure 7As shown, the control chip 221 receives a preset signal, which can be a signal for restarting after the power is turned off, such as a signal for restarting within 5 seconds after the power is turned off. After receiving the preset signal, the control chip 221 outputs a low-level signal to keep the light-emitting element 222 constantly lit. At this time, the light-emitting element 222 can be used as auxiliary lighting. In use, the user can switch the light-emitting element 222 from a flame lamp to full-bright auxiliary lighting, or from full-bright auxiliary lighting to a flame lamp, by pressing the power switch twice briefly.

[0062] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
