Description

Technical Field

[0001] This utility model relates to a magnetic repulsion type levitation lamp. Background Technology

[0002] CN201332374Y discloses a magnetic levitation device that supplies power to a light-emitting element within a levitation body via a wireless transmission device. However, this wireless power supply mode results in excessively low electrical power received by the levitation body, typically no more than 0.5W, severely impacting the normal illumination effect of the light-emitting element. While the magnetic levitation devices disclosed in CN113809832A or WO2023040207A1 can increase transmission power by altering the structure of the wireless transmission coil, their structures are relatively complex and still cannot achieve higher power transmission (e.g., above 5W). Utility Model Content

[0003] The purpose of this invention is to provide a high-power magnetic repulsion type levitation lamp.

[0004] The magnetic repulsion levitation lamp according to this utility model includes: A levitation body having a light receiving channel and a light-scattering device located at the upper exit of the light receiving channel, the light-scattering device including a concave lens and / or a light guide column made of acrylic material; and The levitation device, which uses magnetic repulsion to keep the suspended body in a suspended equilibrium position above it, has a light transmission channel, in which a light-emitting device is installed. The light-emitting device includes: An LED light source and a convex lens are used to converge the light emitted by the LED light source into the light receiving channel. An LED light source and an optical fiber bundle; the light emitted by the LED light source passes through the optical fiber bundle and enters the light receiving channel in parallel; or A laser light source that directly provides parallel light rays. When the suspended body is in a suspended equilibrium position relative to the suspender, the light receiving channel of the suspended body and the light transmitting channel of the suspender are aligned with each other, so that the light emitted by the light-emitting device of the suspender directly enters the light receiving channel from the light transmitting channel and then enters the light diffuser of the suspended body.

[0005] According to this invention, the levitation body may also have a shell made at least partially of a transparent or translucent material, and the entrance to the light receiving channel is formed by a corresponding notch on the shell.

[0006] According to this invention, the suspending body may optionally have a laser-excited fluorescent device located outside the scattering device.

[0007] According to a preferred embodiment of this invention, a light receiving channel runs longitudinally through the levitation body, and a light transmitting channel also runs longitudinally through the levitation body. The light-emitting device further includes a heat sink protruding downward from the light transmitting channel. In this embodiment, the levitation body may also include at least two Hall sensors in the form of integrated circuit chips arranged around the light transmitting channel for detecting the horizontal shift of the levitation body's self-levitation equilibrium position. The magnetic sensing surfaces of the at least two Hall sensors are perpendicular to each other and parallel to the extension direction of the light transmitting channel. This structure minimizes electromagnetic and thermal interference problems, effectively removing potential obstacles to increasing the power of the levitation body lamp.

[0008] The magnetic repulsion type levitation lamp of this invention has a simpler structure and lower cost, and cleverly solves the problem of insufficient power of levitation lamps, and can achieve any required power within, for example, 10W. Attached Figure Description

Detailed Implementation

[0010] The present invention will be further described below with reference to the embodiments and accompanying drawings. Those skilled in the art should understand that the embodiments and accompanying drawings are only for a better understanding of the present invention and are not intended to make any limitations.

[0011] Figure 1 An embodiment of a magnetic repulsion levitation lamp according to the present invention is shown. For example... Figure 1 As shown, the magnetic repulsion type levitation lamp of this utility model includes a levitation device or base 1 and a levitation body 2. The base 1 has a cuboid outer shell 10, and the levitation body 2 has a spherical outer shell or lampshade 20. The lampshade 20 is at least partially made of a transparent or translucent material, for example, it is made of a translucent material in one piece.

[0012] Figure 2 The structure shown has been removed Figure 1The base 1, part of the outer shell 10, and the lampshade 20 of the levitation body 2. Figure 3 for Figure 2 A perspective view of the structure shown. (See diagram below.) Figure 1-3 As shown, the base 1 also includes a ring magnet 12, four electromagnetic coils 13, and integrated circuit Hall sensors 14a and 14b (four are shown in the figure) disposed within the housing 10. The four electromagnetic coils 13 are evenly distributed along the inner circumference of the ring magnet 12, and the Hall sensors 14a and 14b are located inside the electromagnetic coils 13. The light transmission channel 11 is centrally located within the ring magnet 12 and has an upward-facing outlet. The Hall sensors 14a and 14b are arranged around the light transmission channel 11, with their magnetic sensing surfaces perpendicular to each other and parallel to the extension direction of the light transmission channel 11 (vertical direction in the figure). In this way, the magnetic sensing surfaces of each sensor are arranged parallel to the longitudinal direction of the electromagnetic coils, thereby minimizing the magnetic field interference generated by the electromagnetic coils after they are energized; in addition, the eccentric arrangement of each sensor also amplifies its sensitivity to detecting the horizontal displacement of the cylindrical magnet 22. A ring iron plate 120 for enhancing the magnetic field is also provided at the bottom of the ring magnet 12.

[0013] The levitation body 2 also has a cylindrical magnet 22 disposed in the lampshade 20, and the light receiving channel 21 extends centrally through the cylindrical magnet 22. A circular iron plate 220 for enhancing the magnetic field is also disposed on the top of the cylindrical magnet 22.

[0014] A magnetic repulsive force is generated between the cylindrical magnet 22 of the levitation body 2 and the annular magnet 12 of the base 1. When the distance between them is adjusted to a suitable size (a predetermined distance), the gravity of the levitation body 2 is balanced by this magnetic repulsive force, thus placing it in a levitation equilibrium position or a predetermined position above the base 1 or its annular magnet 12. Once the distance between the cylindrical magnet 22 of the levitation body 2 and the annular magnet 12 of the base 1 changes slightly due to air disturbances, this levitation equilibrium of the levitation body 2 relative to the base 1 will be broken. Hall sensors 14a and 14b detect the lateral (horizontal direction shown in the figure) position change of the cylindrical magnet 22 of the levitation body 2 relative to the annular magnet 12 of the base 1 in real time and generate corresponding signals, which are transmitted to a controller, such as a control chip (not specifically shown), installed on the base 1. Based on the position signals transmitted by the Hall sensors 14a and 14b, the controller controls the magnitude and direction of the current flowing through the corresponding electromagnetic coil 13, thereby causing the electromagnetic coil 13 to generate a corresponding electromagnetic force, which acts on the cylindrical magnet 22 of the levitation body 2 to return it to the levitation equilibrium position. The structure and working principle of this magnetic repulsion levitation device can also be found in, for example, the applicant's previous patents CN100544183C and CN105790641B, the entire contents of which are incorporated herein by reference.

[0015] When the levitation body 2 is in a suspended equilibrium position relative to the base 1, the light receiving channel 21 of the levitation body 2 is aligned with the light transmitting channel 11 of the base 1. An LED light source 16 is installed at the lower part of the light transmitting channel 11 of the base 1, and a convex lens 17 is installed at the upper exit. The light emitted by the LED light source 16 is converged by the convex lens 17 and then directly enters the light receiving channel 21 through the notch formed at the lower part of the lampshade 20 of the levitation body 2. A concave lens 23 is installed at the upper exit of the light receiving channel 21 as a light-diffusing device. The light is diffused by the concave lens 23 and then enters and illuminates the lampshade 20 of the levitation body 2.

[0016] The backlight side of the LED light source 16 is also provided with a heat sink in the form of a heat sink plate 15, which protrudes downward from the light transmission channel 11 (located outside the housing 10) and is spaced apart from the electromagnetic coil 13, Hall sensors 14a, 14b and other electronic control components to avoid adverse thermal effects on them.

[0017] Figure 4 It shows Figure 2 A variation of the structure shown is also optional, excluding the lampshade and part of the base housing. Alternative Figure 2 The original uses a concave lens 23 as a scattering device, while this variant uses a light guide post 23' made of transparent acrylic as a scattering device.

[0018] Figure 5 Then it is Figure 2 Another variation of the structure shown. Alternative. Figure 2 The convex lens 17 used in the original design is replaced by an optical fiber bundle 17' arranged in the light transmission channel 11. The light generated by the LED light source 16 is guided by the optical fiber bundle 17' and becomes parallel light before entering the light receiving channel 21. In addition, a fluorescent device 24 is further disposed on the outer side of the concave lens.

[0019] Figure 6 Then it is Figure 2 Another variation of the structure shown. Alternative. Figure 2 The original design used an LED light source 16, while this variant uses a laser light source 16' that can directly emit parallel light, thus omitting the LED light source 16'. Figure 2 The concave lens 17 is further provided with a laser-excited fluorescent device 24' on the outer side of the concave lens.
