Description

Technical Field

[0001] This utility model relates to a magnetic 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 levitation lamp.

[0004] The magnetic levitation lamp according to this utility model includes: A levitation body having a light receiving channel and a light-scattering device located at the lower 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 A magnetic suction head, which uses magnetic attraction to keep the levitated object in a suspended equilibrium position relative to it below, has a light transmission channel, and a light-emitting device is installed in the light transmission channel. 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 levitated body is in a levitated equilibrium position relative to the magnetic head, the light receiving channel of the levitated body and the light transmitting channel of the magnetic head are aligned with each other, so that the light emitted by the light-emitting device of the magnetic head directly enters the light receiving channel from the light transmitting channel and then enters the light diffuser of the levitated 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 in the upper part of 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 this invention, the light receiving channel can be centrally traversed longitudinally through the levitation body, and the light transmitting channel can also be centrally traversed longitudinally through the magnetic head. The light-emitting device can also include a heat sink protruding upward from the light transmitting channel. This structure minimizes the thermal interference problem of the device and effectively removes potential obstacles to increasing the power of the levitation body lamp.

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

[0009] Figure 1 This is a perspective structural diagram of an embodiment of the magnetic levitation lamp according to the present invention; Figure 2 for Figure 1 The cross-sectional structural diagram of the embodiment shown is shown, but the lower structure of the support has been removed and a levitation shell has been added; Figure 3 for Figure 2 The structure shown is a variant; Figure 4 for Figure 2 Another variation of the structure shown; Figure 5 for Figure 2 Another variation of the structure shown. 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 levitation lamp according to the present invention is shown; Figure 2 This is a cross-sectional structural diagram, but the lower structure of support 1 has been removed, and a levitation shell 20 has been added. (See diagram below.) Figure 1 and 2 As shown, the magnetic levitation lamp of this invention includes a bracket 1 and a levitation body 2. A magnetic body 10 is provided on the top of the bracket 1, and the levitation body 2 has a spherical lampshade or outer shell 20. The outer shell 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] The magnetic head 10 has an electromagnetic coil 11 that surrounds the centrally located light transmission channel 12. The levitation body 2 also has a cylindrical magnet 21 disposed in the housing 20, and the light receiving channel 22 extends centrally through the cylindrical magnet 21.

[0013] In this type of magnetic levitation device, which includes a magnetic head and a levitation body, the magnetic head can interact with the levitation body in real time, enabling the levitation body to be stably suspended in a levitation equilibrium position or a set position below the magnetic head through the mutual magnetic attraction between the two. Its specific structure and working principle are well-known in the art and will not be detailed here for the sake of brevity. See, for example, CN2561163Y, the entire contents of which are incorporated herein by reference.

[0014] When the levitation body 2 is in a levitation equilibrium position relative to the magnetic head 10, the light receiving channel 22 of the levitation body 2 and the light transmitting channel 11 of the magnetic head 10 are aligned with each other. An LED light source 13 is provided at the upper part of the light transmitting channel 12 of the magnetic head 10, and a convex lens 15 is provided at the lower exit. The light emitted by the LED light source 13 is converged by the convex lens 15 and then directly enters the light receiving channel 22 through the notch formed at the upper part of the outer shell 20 of the levitation body 2. A light-diffusing device in the form of a concave lens 23 is provided at the lower exit of the light receiving channel 22. The light is diffused by the concave lens 23 and then enters and illuminates the outer shell 20 of the levitation body 2.

[0015] The backlight side of the LED light source 13 is also provided with a heat sink in the form of a heat sink 14, which protrudes upward from the light transmission channel 12 and is spaced apart from the electromagnetic coil 11 and other electronic control components to avoid adverse thermal effects on them.

[0016] Figure 3 It shows Figure 2 A variation of the structure shown. Alternative. Figure 2 The first version uses a concave lens 23 as a scattering device, while the second version uses a light guide post 23' made of transparent acrylic as a scattering device.

[0017] Figure 4 Then it is Figure 2 Another variation of the structure shown. Alternative. Figure 2 In the first version, a convex lens 15 is used. In this variant, an optical fiber bundle 15' is arranged in the light transmission channel 12. The light generated by the LED light source 13 is guided by the optical fiber bundle 15' and becomes parallel light before entering the light receiving channel 22. A fluorescent device 24 is further provided on the outside (below) of the astigmatism device or concave lens.

[0018] Figure 5 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 13' that can directly emit parallel light, thus omitting the LED light source 16. Figure 2 The convex lens 15 is further provided on the outer side of the astigmatism device or concave lens, and a laser-excited fluorescence device 24' is also provided.
