Description

Technical Field

[0001] The present invention relates to the technical field of magnetic levitation lamps, and in particular to a magnetic levitation LED lamp and a use method thereof. Background Art

[0002] The working principle of the magnetic levitation lamp is mainly based on the principle of electromagnetic induction and the interaction of magnetic fields. Specifically, the magnetic levitation lamp usually consists of two parts: a levitator and a bulb. There is a strong magnetic field inside the levitator, which is composed of a magnet coil. The magnet generates a strong magnetic field, and the coil can generate electromagnetic force. When current passes through the coil, the coil generates a magnetic field, and then this magnetic field interacts with the magnetic field of the magnet, which can make the bulb levitate in the air. At the same time, there is a light-emitting body and an electrode inside the bulb. When the bulb is powered on, current will pass through the electrode, causing the light-emitting body to start discharging, thereby generating light.

[0003] The Chinese patent publication number is CN205137182U, which discloses a magnetic levitation lamp, which belongs to the field of mechanical equipment. It solves the problems that the existing technology design is not reasonable. The magnetic levitation lamp includes a base, and a magnetic push-up assembly is provided in the base to enable the lamp assembly to suspend above the base. A magnetic suspension block with the same magnetic pole as the magnetic push-up assembly is connected to the bottom of the lamp assembly. A lampshade is fixed on the outside of the lamp assembly, and the bottom of the lampshade is connected to the magnetic suspension block. A distance sensor for measuring the distance between the lampshade and the base, a control circuit board and a first power supply circuit are provided in the lampshade. The lamp assembly and the distance sensor are respectively connected to the control circuit board, and the control circuit board is connected to the first power supply circuit. The advantages of this magnetic levitation lamp are: reasonable design, simple structure, the use of magnetic principle to suspend the lampshade above the base, and the light brightness is changed according to the data measured by the distance sensor. The structure is novel, the interactivity is good, and the fun is increased.

[0004] The above-mentioned existing technical solutions have the following defects: the magnetic levitation LED lamp is provided with a heat dissipation slot to ensure a good heat dissipation effect, but mosquitoes are phototactic and will drill into the heat dissipation slot. The bodies and secretions of the mosquitoes may be left on the lampshade, leaving stains and odors, which seriously affect the beauty and neatness of the magnetic levitation LED lamp, and also block part of the light, resulting in a decrease in the lighting effect. In addition, if the insects move around the light bulb, it may also affect the heat dissipation of the light bulb, thereby affecting its service life. Therefore, we propose a magnetic levitation LED lamp and its use method to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a magnetic levitation LED lamp and a method of using the same, so as to solve the problem that the magnetic levitation LED lamp is provided with a heat dissipation slot in order to ensure a good heat dissipation effect, but mosquitoes are phototactic and will drill into the heat dissipation slot.

In addition, if the insects move around the light bulb, it may also affect the heat dissipation of the light bulb, thereby affecting its service life.

[0010] Preferably, an LED lamp bead board is fixedly installed on the upper part of the interior of the LED lamp bead board fixing frame, an LED lamp bead board coil is arranged on the outside of the LED lamp bead board, and the cooling fan is located below the LED lamp bead board.

[0011] Preferably, a cooling fan motor is provided below the cooling fan, the cooling fan motor is fixedly connected to the ultrasonic insect repellent mechanism fixing frame below, the output end of the cooling fan motor is drivingly connected to the cooling fan, and the ultrasonic insect repellent mechanism fixing frame is a hollow frame.

[0012] Preferably, a spacing groove of three to five millimeters is provided between the upper end of the LED lamp bead board fixing frame and the outer wall of the LED lamp ball, and the spacing groove is connected with the air outlet groove.

[0013] Preferably, an air induction plate guide groove is provided inside the upper end of the lamp holder, and a shock-absorbing pad is provided on the upper end of the air induction plate guide groove.

[0014] Preferably, the air induction plate is a curved plate, the air induction plate is matched with the air induction plate guide groove, and the LED lamp ball is fitted with the shock-absorbing pad.

[0015] A method for using a magnetic levitation LED lamp comprises the following steps:

[0016] Step 1: Turn on the power of the lamp holder. When the current passes through the coil inside the lamp holder, a magnetic field will be generated. The magnetic field interacts with the magnetic field generated by the fixed magnet block of the LED lamp ball, thereby generating an upward force, causing the LED lamp ball to float in the air. Due to the uniform setting of the coil in the lamp holder, the interaction force is balanced, allowing the LED lamp ball to stably float in the predetermined position.

[0017] Step 2: An LED lamp bead board and an LED lamp bead board coil are installed inside the LED lamp ball, and the transmitting coil on the lamp holder will emit electromagnetic waves, which will generate current in the LED lamp bead board coil through electromagnetic induction, thereby driving the LED lamp bead board to emit light;

[0018] Step 3: Turn on the ultrasonic insect repellent mechanism and the cooling fan motor at the same time. The ultrasonic insect repellent mechanism emits ultrasonic waves. The core component of the ultrasonic insect repellent mechanism is usually a ceramic acoustic wave plate, which uses the reverse piezoelectric principle to convert electrical energy into mechanical stress, thereby generating ultrasonic signals. These signals are transmitted through the speaker toward the air inlet slot. When insects or small pests approach the range of the ultrasonic insect repellent device, they will sense the presence of ultrasonic waves. Due to their sensitive auditory organs, these pests will feel uncomfortable or even painful. In order to escape the interference of ultrasonic waves, they will take escaping actions, so that mosquitoes will not enter from the air inlet slot, and at the same time, the magnetic levitation LED light will have an insect repellent effect. The ultrasonic insect repellent device does not require the use of any chemical agents, has no effect on humans and other large animals, and is easy to operate. Ultrasonic waves will drive the first filter and the second filter to vibrate, and the vibration will cause the dust on the surface of the first filter and the second filter to fall off, thereby preventing dirt blockage, and having a significant cleaning effect, environmental protection and energy saving, strong applicability, and extending the service life of the filter.

[0019] Step 4: The output end of the cooling fan motor drives the cooling fan to rotate. After the cooling fan rotates, negative pressure is generated. The negative pressure allows air to enter through the air inlet slot. The air passes through the first filter and the second filter in turn, and is filtered by the first filter and the second filter, effectively preventing dust and mosquitoes from entering the interior of the LED lamp ball. After passing through the air inlet slot, the air enters the heat dissipation cavity, and the air contacts the LED lamp bead board fixing frame. The temperature generated when the LED lamp bead board emits light exchanges heat with the LED lamp bead board fixing frame. When the air contacts the LED lamp bead board fixing frame, the heat absorbed by the LED lamp bead board fixing frame will be taken away by heat exchange. The air that absorbs the heat flows along the LED lamp bead board fixing frame and then flows out from the air outlet slot. The outflowing air is guided by the air guide plate and flows in an inclined direction. When the ten air outlet slots simultaneously discharge inclined air, the LED lamp ball will rotate with the thrust of the air. The rotated LED lamp ball can prevent mosquitoes from approaching and entering from the air outlet slot.

[0020] Step 5: When the power is cut off unexpectedly, the magnet in the lamp holder and the magnet block of the LED lamp ball attract each other, causing the LED lamp ball to fall quickly. The curved plate structure of the air inlet plate at the lower end of the LED lamp ball is adapted to the air inlet plate guide groove. The inclined air inlet plate converts the downward impact force into an inclined force, thereby consuming part of the impact force through the friction of the falling air inlet plate. The shock-absorbing pad fitted on the upper surface of the air inlet plate guide groove is in contact with the LED lamp ball. When the shock-absorbing pad is impacted, the damping effect of the shock-absorbing pad will convert part of the impact energy into heat energy, thereby reducing the impact on the internal components of the LED lamp ball and protecting the LED lamp ball.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The ultrasonic pest repellent mechanism of the present invention emits ultrasonic waves. The core component of the ultrasonic pest repellent mechanism is usually a ceramic sound wave plate, which uses the reverse piezoelectric principle to convert electrical energy into mechanical stress, thereby generating ultrasonic signals. These signals are transmitted toward the air inlet slot through the loudspeaker. When insects or small pests approach the range of the ultrasonic insect repellent device, they will sense the presence of ultrasonic waves. Due to their sensitive auditory organs, these pests will feel uncomfortable or even painful. In order to escape the interference of ultrasonic waves, they will flee, so that mosquitoes will not enter from the air inlet slot, and the magnetic levitation LED light will have an insect repellent effect. The ultrasonic insect repellent device does not require the use of any chemical agents, has no effect on humans and other large animals, and is easy to operate. Ultrasonic waves will drive the first filter and the second filter to vibrate, and the vibration will cause the dust on the surface of the first filter and the second filter to fall off, thereby preventing clogging, with significant cleaning effects, environmental protection and energy saving, strong applicability, and extended filter life; the output end of the cooling fan motor drives the cooling fan to rotate, and the cooling fan generates negative pressure after rotation. The negative pressure allows air to enter through the air inlet slot, and the air passes through the first filter and the second filter in turn, and is filtered by the first filter and the second filter, effectively preventing dust and mosquitoes. The air passes through the air inlet groove and enters the heat dissipation cavity, and the air contacts the LED lamp bead board fixing frame. The temperature generated when the LED lamp bead board emits light exchanges heat with the LED lamp bead board fixing frame. When the air contacts the LED lamp bead board fixing frame, the heat absorbed by the LED lamp bead board fixing frame will be taken away by heat exchange, and the air that has absorbed the heat flows along the LED lamp bead board fixing frame, and then flows out from the air outlet groove. The outflowing air flows in an inclined direction as guided by the air induced plate. When the ten air outlet grooves flow out the inclined air at the same time, the LED lamp ball will rotate with the thrust of the air. The rotating LED lamp ball can prevent mosquitoes from approaching and entering from the air outlet groove, which solves the problem that the magnetic levitation LED lamp will be equipped with a heat dissipation groove to ensure a good heat dissipation effect, but mosquitoes are phototactic, and they will drill into the heat dissipation groove. The bodies and secretions of the mosquitoes may be left on the lampshade, leaving stains and odors, which seriously affect the beauty and cleanliness of the magnetic levitation LED lamp, and also block part of the light, resulting in a decrease in the lighting effect. In addition, if insects move around the light bulb, it may affect the heat dissipation of the light bulb, thus affecting its service life.

[0023] 2. When the power is cut off unexpectedly in the present invention, the magnet in the lamp holder and the magnet block of the LED lamp ball are attracted to each other, causing the LED lamp ball to fall quickly. The curved plate structure of the air inlet plate at the lower end of the LED lamp ball is adapted to the guide groove of the air inlet plate. The inclined air inlet plate converts the downward impact force into an inclined force, thereby consuming a part of the impact force through the friction of the falling air inlet plate. The shock-absorbing pad fitted on the upper surface of the guide groove of the air inlet plate is in contact with the LED lamp ball. When the shock-absorbing pad is impacted, the damping effect of the shock-absorbing pad will convert a part of the impact energy into heat energy, thereby reducing the impact on the internal components of the LED lamp ball and protecting the LED lamp ball.

[0040] A method for using a magnetic levitation LED lamp comprises the following steps:

[0041] Step 1: Turn on the power of the lamp holder 1. When the current passes through the coil inside the lamp holder 1, a magnetic field is generated. The magnetic field interacts with the magnetic field generated by the fixed magnet block 14 of the LED lamp ball 2, thereby generating an upward force to suspend the LED lamp ball 2 in the air. Due to the uniform arrangement of the coil inside the lamp holder 1, the interaction force is balanced, so that the LED lamp ball 2 can be stably suspended at a predetermined position.

[0042] Step 2: An LED lamp bead board 6 and an LED lamp bead board coil 7 are installed inside the LED lamp ball 2, and the transmitting coil on the lamp holder 1 emits electromagnetic waves, which generate current in the LED lamp bead board coil 7 through electromagnetic induction, thereby driving the LED lamp bead board 6 to emit light;

[0043] Step 3: Turn on the ultrasonic insect repellent mechanism 10 and the cooling fan motor 12 at the same time. The ultrasonic insect repellent mechanism 10 emits ultrasonic waves. The core component of the ultrasonic insect repellent mechanism 10 is usually a ceramic acoustic wave plate, which uses the reverse piezoelectric principle to convert electrical energy into mechanical stress, thereby generating ultrasonic signals. These signals are transmitted toward the air inlet slot 8 through the speaker. When insects or small pests approach the range where the ultrasonic insect repellent device is located, they will sense the presence of ultrasonic waves.

[0044] Step 4: The output end of the cooling fan motor 12 drives the cooling fan 13 to rotate. After the cooling fan 13 rotates, negative pressure is generated. The negative pressure allows air to enter through the air inlet slot 8. The air passes through the first filter 15 and the second filter 16 in turn, and is filtered by the first filter 15 and the second filter 16, effectively preventing dust and mosquitoes from entering the interior of the LED lamp ball 2. After passing through the air inlet slot 8, the air enters the heat dissipation cavity 9, and the air contacts the LED lamp bead board fixing frame 5. The temperature generated when the LED lamp bead board 6 emits light is the same as that of the LED lamp bead. The board fixing frame 5 performs heat exchange. When the air contacts the LED lamp bead board fixing frame 5, the heat absorbed by the LED lamp bead board fixing frame 5 is taken away by heat exchange. The air that absorbs the heat flows along the LED lamp bead board fixing frame 5 and then flows out from the air outlet slot 4. The outflowing air is guided by the air guide plate 3 and thus flows in an inclined direction. When the ten air outlet slots 4 simultaneously flow out inclined air, the LED lamp ball 2 will rotate with the thrust of the air. The rotated LED lamp ball 2 can prevent mosquitoes from approaching and entering from the air outlet slot 4.

[0045] Step 5: When the power is cut off unexpectedly, the magnet in the lamp holder 1 and the magnet block 14 of the LED lamp ball 2 are attracted to each other, causing the LED lamp ball 2 to fall quickly. The curved plate structure of the air inlet plate 3 at the lower end of the LED lamp ball 2 is adapted to the air inlet plate guide groove 17. The inclined air inlet plate 3 converts the downward impact force into an inclined force, thereby consuming a part of the impact force through the friction of the falling air inlet plate 3. The shock-absorbing pad 18 attached to the upper surface of the air inlet plate guide groove 17 is in contact with the LED lamp ball 2. When the shock-absorbing pad 18 is impacted, the damping effect of the shock-absorbing pad 18 will convert a part of the impact energy into heat energy, thereby reducing the impact on the internal components of the LED lamp ball 2 and protecting the LED lamp ball 2.

The air that has absorbed the heat flows along the LED lamp bead board fixing frame (5) and then flows out from the air outlet slot (4). The outflowing air is guided by the air guide plate (3) and thus flows in an inclined direction. When the ten air outlet slots (4) simultaneously flow out inclined air, the LED lamp ball (2) rotates with the thrust of the air. The rotating LED lamp ball (2) can prevent mosquitoes from approaching and entering from the air outlet slot (4). Step 5: When the power is unexpectedly cut off, the magnet in the lamp holder (1) and the magnet block (14) of the LED lamp ball (2) are attracted to each other, causing the LED lamp ball (2) to fall rapidly. The curved plate structure of the air induction plate (3) at the lower end of the LED lamp ball (2) is matched with the air induction plate guide groove (17). The inclined air induction plate (3) converts the downward impact force into an inclined force, thereby consuming a part of the impact force through the friction of the air induction plate (3) falling. The shock absorbing pad (18) attached to the upper surface of the air induction plate guide groove (17) contacts the LED lamp ball (2). When the shock absorbing pad (18) is impacted, the damping effect of the shock absorbing pad (18) converts a part of the impact energy into heat energy, thereby reducing the impact on the internal components of the LED lamp ball (2), thereby protecting the LED lamp ball (2).
