To address the shortcoming which the omamental value is low due to the limitation of the shape and structure of the lampshade in the prior art, the invention provides a self-luminous suspension lamp.

Referring to Figure 1, the self-luminous suspension lamp comprises a floater and a base configured below the floater, an electromagnetic coil configured in the base and a suspension control system connected to the electromagnetic coil.

According to one embodiment of the présent invention, a light-emitting device and a magnet are configured in the floater, the magnet generates an opposite magnetic field to the electromagnetic coil during the operation of the suspension lamp, the magnet suffers a repelling force in an upward direction, the repelling force generated by the electromagnetic coil is balanced with the gravity of the whole floater (including light-emitting device and magnet) so that the floater is suspended. Preferably, the light-emitting device is a LED light.

Preferably, in an embodiment of the présent invention, there are two electromagnetic coïls, a Hall sensor is configured between two electromagnetic coils and is configured in the base. The Hall sensor is connected to the suspension control system. When the floater changes its position, the Hall sensor can detect the feedback signal which reflects the variation of the magnetic field intensity of the electromagnet configured in the floater, and sends the feedback signal to the suspension control system. The suspension control system varies the magnetic force generated by the magnetic field of the electromagnetic coil in real time, so that the rebelling force of the floater offsets the gravity of the floater, and the floater is suspended in an optimal suspension position. The suspension control system is also connected to a power amplifier (the suspension control system varies the magnetic field intensity of the electromagnetic coil by adjusting output power of the power amplifier), the power amplifier is connected to the electromagnetic coil so as to vary the magnetic field generated by the electromagnetic coil in real time.

When the LED light emits light beam on the floater, it is possible to make the emitting beam of the LED light distribute on the floater evenly, so as to increase the scope of design for the structure and shape of the suspension lamp. A charge coil, configured in the floater, provides the power to the LED. The magnetic field generated by the charge coil in the floater is varied by varying the magnetic field of the electromagnetic coil, so that the charge coil generates the induced electromotive force to drive the LED light to be self-luminous continually.

In the self-luminous suspension lamp, a wireless charging system

T5 is configured in the base. The wireless charging System is connected to one of the electromagnetîc coils, the suspension control System is connected to the other. The wireless charging system comprises a wireless power controller, a first power converting module connected to the wireless power controller, a full bridge converting module connected to the wireless power controller and a variable output module connected to the wireless power controller, wherein the full bridge converting module is connected to the variable output module. To provide the power to the electrical energy of the electromagnetîc coil or the variation of the electric field continually, a further power supply (such as the voltage is 12V or other output voltage values) is required. The power supply is connected to the first power converting module, and is connected to the suspension control system through the second power converting module. Preferably, the second power converting module is configured in the base. On the one hand, when the power supply outputs the voltage, the first power converting module decreases the voltage (such as 3V) and transmits the decreased voltage to the wireless power controller. The wireless power controller adjusts the output power directly or by the variable output module, the power is then provided to the full bridge converting module. The full bridge converting module is connected to the electromagnetîc coil. The full bridge converting module receives the corresponding power, and outputs the alternating voltage to form the alternating magnetic field in the electromagnetic coil. Because the magnetic field in the electromagnetic coil is varied, the charge coil in the corresponding floater generates the induced electromotive force to drive the LED light to be self-luminous continually. On the other hand, when the power supply outputs the voltage, the first power converting module decreases the voltage (such as 3V) and transmits the decreased voltage to the wireless power controller. The wireless power controller varies the magnetic field by the power amplifier so that the floater is suspended stably.

Meanwhile, the self-luminous suspension lamp provided by the invention illuminâtes the lamp by internai LED light, thus the whole lamp is shine. The lamp can be round or other shapes. The suspension lamp placed in home not only can be a illumination, but also is a beautiful omament. For example, in an optional solution, a self-luminous suspension tellurion according to the invention acts as a floater suspended on a base. At présent, the présent suspension tellurion can not be luminous. It can be shine by reflecting the light emitted by external light, therefore only local map illuminated can be seen in the tellurion. By adopting the technology according to the invention, the whole tellurion is luminous and any point of it can be seen, this is not achieved by the prior art.
