Description

Fountain and lighting apparatus using a low voltage induction}

The present invention relates to a fountain lighting device, and more particularly, to perform a fountain function by driving an underwater pump using an AC power input from the outside, and also to induce a low voltage from the driving power source of the submersible pump to provide a light emitting device. The present invention relates to a fountain lighting device using low voltage induction that can also perform a lighting function.

In general, a fountain lighting device having a conventional fountain function and an illumination function is a driving power source for performing each function, and receives a fountain driving power source and an AC power source for a lighting driving power source from the outside, respectively. Therefore, every time you add other functions to the fountain lighting device, you need to add the external driving power according to the number of additional functions. Therefore, this phenomenon is excessive because several external powers are used to perform the functions of the fountain lighting device. The load is anxious and causes a lot of power loss. In addition, when the covering of the wires connected to each device is peeled off when performing the lighting function, this may cause an electric shock because the high voltage input from the outside flows as it is. As a result, the number of times of ornamental use in public places such as parks and banquet halls, as well as ordinary homes, is increasing. Nowadays, various functions can be performed simultaneously from a single source power source. There is a need for a fountain light that provides extremely low power without the risk of electric shock if hands are touched or children are touched bare wires.

Accordingly, an object of the present invention is to use the external alternating current power source of the external rotor as a driving power source for the submersible pump, and also to drive the lighting by inducing a low voltage without risk of electric shock from the submersible pump driving power source. The present invention provides a fountain lighting apparatus using low voltage.

To waterproof It is provided with a waterproof case 600 filling the interior with a vagina (700).

FIG. 2 (b) shows the flow of the AC power 500 to the wound primary coil 160, the secondary coil 180, and the submersible pump driving unit 100 of the low voltage induction unit 100. A core for connecting the first bobbin 120 and the second bobbin 121 and the first bobbin 120 and the second bobbin 121 to which the first coil 120 and the second coil 180 are respectively wound and arranged side by side. One end is connected to one end of the AC power supply 500 while the first bobbin 121 is wound on the primary coil 160 and the second bobbin 121 that receives the AC power supply 500 as an input. While winding in), one end is connected to the other end of the primary coil 160 and the other end is connected to the other end of the AC power source 500 is input from the outside to input the output of the primary coil 160 Received by the secondary coil 180, the tertiary coil 190 is wound on the secondary coil 180 to receive the operating power for illuminating the LED of the lighting unit 300, and Insulating the insulating means 170, the secondary coil 180, and the tertiary coil 190, which are present on the wound coil 160, to prevent the primary coil 16 from coming into contact with foreign matter. Insulating means 174 provided between the coils 180 and 190 and the insulating means 174 provided on the coiled coil 190 to prevent the tertiary coil 190 from coming into contact with foreign matter. For example, the use of insulating paper as an insulating means will be described below).

FIG. 2 (c) is a view illustrating a connection relationship between the wound tertiary coil 190 and the lighting unit 300. An insulating material (insulating means) is formed on the secondary coil 180 wound on the second bobbin 121 ( By covering the 170 and winding the tertiary coil 190 thereon, the short circuit of the secondary coil 180 and the tertiary coil 190 is prevented. In addition, the tertiary coil 190 is extremely smaller than the original voltage (AC220V flowing in the secondary coil 180) by the induction action with the current flowing in the secondary coil 180, and is harmless to humans (3 to 6V). This occurs, and the generated low voltage is used as a power source for illuminating a plurality of LEDs of the lighting unit 300. Here, the third coil 190 may vary the number of coils and the thickness of the coil in order to generate an induced current of a different size through an induction action (for example, in the device of the present invention, the secondary coil 180 and The winding ratio of the tertiary coil 190 is 10: 1.)

FIG. 2 (d) shows a cross section taken along the line AA in FIG. 2 (c), and as can be seen from the drawing, the core 140-bobbin 121, and the secondary coil thereon from the innermost side. It is wound in the order of (180) -insulation means 172-third coil 190-insulation means 174.

The operation of the present invention configured as described above will be described in detail with reference to FIGS. 1 to 2 (d) as follows.

First, the AC power 500 introduced from the outside drives the submersible motor inside the submersible pump driving unit 200, and the water in the drainage pipe is discharged through the drainage pipe 250 due to the rotational force of the impeller due to the rotational force when the submersible motor operates. It will erupt up and perform a fractional function. At this time, the stone ball 260 placed on the spout due to the power output of the water is rotated. In addition, the submersible motor driving power of the submersible pump driving unit 200 is used as a driving power source for generating a predetermined induction voltage in the low voltage induction unit 100 connected in parallel. The driving power flows through the primary coil 160 to the secondary coil 180, in which the space is formed in the insulating means 170 existing between the secondary coil 180 and the tertiary coil 190. Induced electromotive force is generated and induced current flows in the tertiary coil. The induced current is controlled to lower the number of windings and thickness of the tertiary coil to operate light emitting devices such as LEDs with a considerably lower current than the initial driving power. Only enough is there is no risk of electric shock to the user at all. Thus, by adjusting the winding ratio and the thickness of the tertiary coil 190 according to the threshold value of the light emitting devices, the user can obtain the induced current of the desired size, and the same from the primary coil 160 as well as the secondary coil 180. The induced current can be obtained by the method.

As described above, since the decorative fountain lighting device using the low voltage induction of the present invention can perform both the fountain function and the lighting function with a single power source input from the outside, a plurality of external source inputs are required for the multifunction. Unlike conventional technology, power consumption can be greatly reduced, and in the case of using a conventional transformer, cost reduction in terms of installation is not necessary since elements such as diodes or capacitors, which are always accompanied to prevent damage of passive devices due to overload, are not required. There is an advantage. In addition, even if the covering of the electric wire that supplies power to the lighting unit is located in the water of the drain pipe, the electric current flowing through the electric wire is a low electric current that cannot be felt by humans. Therefore, the present invention can be used as a decoration for aesthetics by placing in a living room, a banquet hall and a public place in a general home, can be used as a substitute for bedtime, and at the same time can also obtain a humidification effect through the fountain function. have.
