Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in figure 1, the desk lamp with the suspensible lampshade comprises a lampshade 1, a base 2 and an energy-saving bulb 3, wherein a main switch and a sliding touch switch are arranged on the surface of the base 2, the main switch is a single-pole double-throw switch, a lamp holder is fixedly installed in the center of the base 2 through a support column, the energy-saving bulb 3 can be screwed into the lamp holder, a support plate 4 is fixedly welded above the energy-saving bulb 3 through a support rod, an electromagnet 5 and a control circuit thereof are fixedly installed inside the support plate 4, in the control circuit, the electromagnet 5 is connected with a sliding rheostat, the energy-saving bulb 3, the position I of the main switch and a power supply in series, the sliding rheostat can be adjusted through the sliding touch switch at the position of the base 2, a cylindrical limiting plate 6 is fixedly installed at the top of the support plate 4, a circular permanent magnet 7 is clamped inside the limiting plate 6, the top of the permanent magnet 7 is fixedly connected with the top of the inner wall of the lampshade 1 through the support rods which are symmetrically distributed in the circumferential direction, this kind of spacing mounting means can keep the permanent magnet 7 balanced in limiting plate 6, prevents to block, through adjusting the slide rheostat, not only can increase the return circuit in the electric current size, increase illumination intensity, can adjust the magnetic field intensity that electro-magnet 5 produced moreover to increase the repulsion between electro-magnet 5 and the permanent magnet 7, when increase illumination intensity, support lamp shade 1 and constantly rise, enlarge the irradiation area of light under the lamp shade, provide sufficient light for reading. As shown in fig. 2, 1 inner wall bottom circumference of lamp shade encircles and installs LED lamp area 8, LED lamp area 8 and permanent magnet 7 electric connection, as shown in fig. 3, 4 fixed mounting of backup pad of permanent magnet 7 below have two pieces of spring 9, spring 9 and main switch's switch position two and power series connection, switch over to position two from position one when the main switch, 5 place return circuits of electro-magnet cut off the power, 7 whereabouts of permanent magnet, contact bottom spring 9 back, switch-on power and LED lamp area 8 are its power supply, not only for the desk lamp has increased the night-light mode, the practicality of desk lamp has been improved, and spring 9 has still played certain protection cushioning effect, and easy operation.

Furthermore, in the control circuit, the electromagnet 5 and the sliding rheostat are externally connected with a super capacitor and a resistor in parallel, when the control circuit is electrified and repulsion force is generated between the electromagnet 5 and the permanent magnet 7 to enable the lampshade to suspend, the super capacitor connected in parallel is continuously charged, the main switch is switched, when the control circuit is cut off, the series circuit is powered off, and due to the energy storage effect of the capacitor, the electromagnet 5 connected in parallel can be discharged, the magnetic force of the electromagnet 5 is temporarily maintained, so that the permanent magnet 7 suspended at a high position cannot immediately fall down, and the buffering effect is further achieved.

Further, as shown in fig. 3, a limiting inner buckle plate is arranged at the top of the limiting plate 6 to prevent the permanent magnet 7 from being pushed out of the limiting plate 6 due to too large repulsive force, and further fix the lampshade 1.
