Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A magnetic suspension lamp decoration for non-contact power, structure as shown in Figure 1, comprises electromagnetic suspension module, noncontact transmission of electricity module and LED 6 and forms.
Wherein, electromagnetic suspension module is formed by with the coil 2 of ferromagnetic core 1 and hall effect sensor 4.Electromagnetic suspension module installation is in top, and ferromagnetic core 1 is inserted in coil 2 inside, and the magnetic of coil 2 is strengthened greatly, and the effective range worked by electromagnet is expanded downwards.LED 6 is arranged on the below of coil 2.
In the bottom of ferromagnetic core 1 and LED 6, respectively magnet is installed, realizes the magneticaction of electromagnet to suspension.Hall effect sensor 4 is respectively arranged with at the two ends of ferromagnetic core 1, the position of LED 6 is determined by its differential signal, the difference of differential signal causes the electric current of electromagnet winding different, thus the electromagnetic force produced also can change, by continuous adjustment, make electromagnetic force identical with the weight of LED 6, LED 6 just can realize suspending.
Noncontact transmission of electricity module comprises transmitting terminal and receiving terminal, and transmitting terminal is the bottom that primary resonance transformer coil 3 is arranged on ferromagnetic core 1, and vertical with ferromagnetic core 1; Receiving terminal is that secondary coil 5 is arranged on by the magnet of LED 6, placement parallel with magnet.
As shown in Figure 2, the transmitting terminal of noncontact transmission of electricity module, under the control of integrated chip XKT-408A, chip T5336 exports a controlled low-voltage, and then the voltage difference control L of output voltage by DC voltage and T5336
1and C
3lC oscillating circuit, launch stable frequency electromagnetic waves.Wherein transmitting coil wire diameter 0.5mm, coil outer diameter 38mm, inductance value 30uH.
As shown in Figure 3, the receiving terminal of noncontact transmission of electricity module, when receiving coil is near transmitting coil, produces induced-current in receiving coil.Here the alternating signal adopting big current custom chip T3168 to be obtained by receiving terminal transfers the direct current signal of 5V to, and its size of current reaches 500mA, and has stronger rear class driving force, effectively for lamp decoration is powered, and can realize other functions various.
Energising primary resonance transformer coil 3 produce alternating magnetic field be coupled to receiving terminal secondary coil 5 so that by electrical energy transfer to LED 6, realize bulb powered.
Consider the such environmental effects such as electromagnetic interference, adopt the position being detected neighbouring permanent magnet by hall effect sensor 4.The differential feedback signal of two Hall elements 4 is utilized to come the position of induced magnetism suspended substance, for the signal disturbing of any permanent magnet, stable or the PWM noise of high frequency all can produce compensation to a certain degree, in feedback signal, be only left the component of positional information, signal to noise ratio improves greatly.After artificial setting suspended substance to assigned address, hall effect sensor 4 detects the impact that in suspended substance, electromagnet produces surrounding magnetic field, produces the corresponding signal of telecommunication.This signal of telecommunication, after differential amplifier circuit process, changes the size of current in coil 2, thus changes the magnetic force of electromagnet, and suspended substance is stressed to change, and the position of suspended substance offsets.Hall element constantly feeds back the positional information of suspended substance, forms closed loop transmission.After the adjustment of short time, suspended substance is stressed reaches balance, is suspended in setting position.When there is a small amount of disturbance in the environment, system still can make it recover stable by closed loop feedback.
In electromagnetic suspension module, hall effect sensor 4 is indium antimonide Hall HW101A, and its sensitivity and stability all can meet the demands.Coil 2 adopts the solenoid of 600 astragal footpath 0.3mm, debugs by analysis, can reach the effect that small-sized electromagnet is suspended, and the quality of levitated object can reach 300g.
LED 6 can be about the position suspension luminescence at 5mm-10mm place apart from footstock, after power-off, bulb can't drop, but is adsorbed to footstock due to the effect of the magnet at bulb top, achieves expectation function well.
