Description

Technical Field

[0001] This utility model relates to a lamp, and more particularly to a simulated flame lamp head. Background Technology

[0002] Existing simulated flame lamps generally include a lamp head, a flame component, a light emitter, a drive mechanism, and a PCB board. The flame component is mounted on the lamp head, and the light emitter projects light onto the flame component. Simultaneously, the PCB board controls the drive mechanism to make the flame component oscillate, achieving the simulated effect. There are two types of flame components: one is a sheet-like structure where the light emitter is external to the lamp head and projects its light onto the flame sheet; the other is a bulb-like structure where the light emitter is internally placed inside a flame bulb and connected to the PCB board via wires. The PCB board controls the light emitter to emit light, thus illuminating the entire bulb. However, the first method results in significant light loss after projection onto the flame sheet, leading to insufficient brightness and poor simulation. The second method requires the light emitter to oscillate with the bulb; prolonged oscillation can cause the two wires soldered to the lamp base to break, leading to malfunctions and shortening the lamp's lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a simulated flame lamp head with high brightness, good simulation effect, and long service life.

[0004] To achieve the above objectives, this utility model provides a simulated flame lamp head, including a housing, a flame bulb, a swing bracket, a support frame, a light-emitting element, a driving mechanism, and a control circuit board. The support frame is fixed inside the housing, and a light-transmitting support portion is provided in the middle of the support frame. The upper end of the support portion has a conical structure, and a first receiving cavity is provided inside the support portion, with an opening on the lower side of the first receiving cavity. The light-emitting element is disposed in the first receiving cavity and electrically connected to the control circuit board. The swing bracket has a mounting portion and a light-transmitting focusing portion. The mounting portion has an opening that passes through both sides, and a second receiving cavity is provided at the top of the opening. The support portion is housed in the second receiving cavity, and the conical tip of the support portion abuts against the top of the second receiving cavity. The focusing portion is disposed at the upper end of the mounting portion and located inside the flame bulb. The flame bulb is connected to the upper end of the mounting portion and located outside the upper end of the housing. The driving mechanism is disposed inside the housing and electrically connected to the control circuit board to drive the swing bracket to swing. Compared with existing technologies, this utility model, by setting up a support frame, a swing bracket, and a flame bulb, divides the swing bracket into a mounting part and a focusing part, and connects the flame bulb to the focusing part. A conical support part is provided on the support frame, with a first receiving cavity inside, where the light-emitting element is placed. Simultaneously, a second receiving cavity is provided on the mounting part of the swing bracket, where the support part is housed. The conical tip of the support part abuts against the top of the second receiving cavity, allowing the swing bracket to be mounted on the support frame. Furthermore, the flame bulb can swing with the swing bracket, while the light-emitting element does not need to swing with the flame bulb, thus preventing breakage of the lamp base wire and effectively extending the lifespan of the flame lamp. In addition, since the support part is designed to be light-transmitting and the light-concentrating part is also designed to be light-transmitting and light-concentrating, most of the light emitted by the light source can be concentrated into the interior of the flame bubble after passing through the support part and the light-concentrating part. Therefore, the brightness of the flame bubble is greatly improved, thereby enhancing the simulation effect.

[0005] Preferably, the light-concentrating part is a convex lens. By utilizing the light-concentrating effect of the convex lens, most of the light emitted by the light source can be focused into the interior of the flame bulb, thereby greatly improving the brightness of the flame bulb.

[0006] Preferably, the support frame includes a crossbar, with both ends of the crossbar fixed to the inner wall of the housing, and the support portion fixed to the middle of the crossbar. This provides strong and stable support to the support portion, ensuring the stability of the swing bracket during swaying.

[0007] Preferably, the driving mechanism includes an electromagnet and a permanent magnet. The electromagnet is connected inside the housing, and the permanent magnet is connected to the lower bottom surface of the mounting portion. The electromagnet drives the permanent magnet through an electromagnetic field, causing the swing bracket to swing. By utilizing the interaction of the electromagnetic forces of the electromagnet and the permanent magnet, not only is the purpose of driving the flame bubble shell achieved, but no noise is generated during the driving process, resulting in excellent quiet operation.

[0008] Preferably, the volume of the cone-shaped support is smaller than the volume of the second accommodating cavity. This allows for a certain gap between the outer wall of the support and the inner wall of the second accommodating cavity, providing space for the mounting portion to swing freely and ensuring the simulation effect of the flame.

[0009] Preferably, the diameter of the mounting portion gradually increases from one end near the focusing portion to the other end. This allows the center of gravity of the mounting portion to be closer to the lower end, which is beneficial for the drive mechanism and allows it to swing under the influence of gravity after being driven by the drive mechanism, resulting in more stable swaying.

[0010] Preferably, the housing includes a left housing and a right housing, the left housing and the right housing being detachably connected; both the side walls of the left housing and the right housing are provided with mounting holes, and the two ends of the support frame are respectively fixedly connected to the mounting holes. By setting the housing as a combination of left and right halves, the assembly of the entire lamp head is made more convenient and quicker.

[0011] Preferably, the second accommodating cavity has a conical structure.

[0012] Preferably, a connecting part is provided between the mounting part and the focusing part, and a boss protrudes outward from the outer periphery of the connecting part. A groove is formed between the boss and the focusing part, and the bottom edge of the flame bulb is engaged in the groove. Attached Figure Description

[0018] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please see Figures 1 to 5The simulated flame lamp head 100 of this utility model includes a housing 1, a flame bulb 2, a swing bracket 3, a support frame 4, a light-emitting element 5, a driving mechanism 6, and a control circuit board 7. The housing 1 has an internal cavity 1a, and the swing bracket 3, support frame 4, light-emitting element 5, driving mechanism 6, and control circuit board 7 are all disposed within the cavity 1a of the housing 1. The support frame 4 has a light-transmitting support portion 41 in its middle. The upper end of the support portion 41 has a conical structure, and the support portion 41 has a first receiving cavity 411 with an opening at its lower side. The light-emitting element 5 is disposed within the first receiving cavity 411 through the opening and is electrically connected to the control circuit board 7; the light-emitting element 5 is an LED lamp. The swing bracket 3 has a mounting portion 31 and a light-transmitting focusing portion 32. The mounting portion 31 has openings 311 extending through both sides, and the top of the openings 311 has a conical second receiving cavity 312. The support portion 41 is housed within the second accommodating cavity 312, with the conical tip of the support portion 41 abutting against the inner top of the second accommodating cavity 312. The focusing portion 32 is disposed at the upper end of the mounting portion 31, and the focusing portion 32 and the mounting portion 31 are integrally formed. The flame bulb 2 has an inner cavity 21, which communicates with the outside through the bottom surface of the flame bulb 2. The focusing portion 32 is connected to the flame bulb 2 and located within the inner cavity 21 of the flame bulb 2. The top of the focusing portion 32 is arc-shaped, and the focusing portion 32 is a solid structure, thus forming a convex lens; utilizing the focusing effect of the convex lens, most of the light emitted by the light source 5 can be focused into the interior of the flame bulb 2, thereby greatly improving the brightness of the flame bulb 2. The upper end face of the housing 1 is provided with a through hole 1b, which communicates with the cavity 1a of the housing 1. The focusing part 32 extends out of the upper part of the housing 1 through the through hole 1b. The flame bulb 2 is connected to the upper end of the mounting part 31 and is located outside the upper part of the housing 1, forming the shape of a flame. More specifically, a connecting part 33 connects the mounting part 31 and the focusing part 32. The outer periphery of the connecting part 33 has a protruding boss 331, which forms a groove 332 between the boss and the focusing part. After the flame bulb 2 is fitted onto the focusing part 32, the bottom edge of the flame bulb 2 is engaged in the groove 332. The driving mechanism 6 is disposed in the cavity 1a and electrically connected to the control circuit board 7 to drive the swing bracket 3 to swing.

[0020] Please see Figures 2 to 4The support frame 4 includes a crossbar 42. The cross-sectional area of ​​the opening 311 is larger than that of the crossbar 42, allowing the crossbar 42 to pass through the opening 311 with a clearance fit, ensuring that the swing bracket 3 can swing. Both ends of the crossbar 42 are fixed to the inner wall of the housing 1, and the support part 41 is fixed to the middle of the crossbar 42. The crossbar 42 provides strong and stable support to the support part 41, ensuring the stability of the swing bracket 3. More specifically, the housing 1 includes a left housing 11 and a right housing 12, which are detachably connected. Mounting holes 1c are provided on the side walls of both the left and right housings, and both ends of the crossbar 42 of the support frame 4 are fixedly connected to the mounting holes 1c. By configuring the housing 1 as a left and right halves, the assembly of the entire lamp head becomes more convenient and faster.

[0021] Please see again Figure 2 The driving mechanism 6 includes an electromagnet 61 and a permanent magnet 62. The electromagnet 61 is connected inside the housing 1. In this embodiment, the electromagnet 61 is mounted on the control circuit board 7, which is fixed to the lower interior of the housing 1. The permanent magnet 62 is connected to the lower bottom surface of the mounting part 31. The control circuit board 7 intermittently energizes the electromagnet 61, causing it to intermittently generate a magnetic field, thereby driving the permanent magnet 62 through the electromagnetic field, causing the swing bracket 3 to swing. By utilizing the interaction of the electromagnetic forces of the electromagnet 61 and the permanent magnet 62, not only is the purpose of driving the flame bubble 2 achieved, but no noise is generated during the driving process, resulting in excellent quiet operation. Of course, in other embodiments, the driving mechanism 6 can also be configured as a mechanical driving device. For example, a motor can drive a lever to move the mounting part 31, causing the swing bracket 3 to swing; or a fan or blower can be used to blow the swing bracket 3.

[0022] Please refer to the following: Figure 3 The volume of the cone-shaped support portion 41 is smaller than the volume of the cone-shaped second accommodating cavity 312. This allows for a certain gap between the outer wall of the support portion 41 and the inner wall of the second accommodating cavity 312, providing space for the mounting portion 31 to swing freely and ensuring the simulation effect of the flame.

[0023] Please refer to the following: Figure 2 The diameter of the mounting part 31 gradually increases from one end near the light-concentrating part 32 to the other end. This allows the center of gravity of the mounting part 31 to be closer to the lower end, which is beneficial for the drive mechanism 6 to drive, and also allows it to swing under the action of gravity after being driven by the drive mechanism 6, making the swing more stable.

[0024] Compared with the prior art, this utility model, by setting up a support frame 4, a swing bracket 3, and a flame bulb 2, divides the swing bracket 3 into a mounting part 31 and a focusing part 32, and connects the flame bulb 2 to the focusing part 32. A conical support part 41 is provided on the support frame 4, with a first receiving cavity 411 inside, where the light emitter 5 is placed. Simultaneously, a conical second receiving cavity 312 is provided on the mounting part 31 of the swing bracket 3, where the support part 41 is housed. The conical tip of the support part 41 abuts against the top of the second receiving cavity 312, thus allowing the swing bracket 3 to be mounted on the support frame 4. Furthermore, the flame bulb 2 can swing with the swing bracket 3, while the light emitter 5 does not need to swing with the flame bulb 2, thereby preventing the lamp base wire of the light emitter 5 from breaking and effectively extending the service life of the flame lamp. In addition, since the support part 41 is designed to be light-transmitting and the light-concentrating part 32 is also designed to be light-transmitting and light-concentrating, most of the light emitted by the light-emitting body 5 can be concentrated into the interior of the flame bubble 2 after passing through the support part 41 and the light-concentrating part 32. Therefore, the brightness of the flame bubble 2 is greatly improved, thereby enhancing the simulation effect.

[0025] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model shall still fall within the scope of the present utility model.
