Description

  The present invention relates to an integrated low voltage power supply for a decorative light used for a decorative light used outdoors and the like.

There are widely known decorative lights that are decorated with many small lights such as miniature bulbs and LED lights on an outdoor tree or Christmas tree, and light up by flashing these lights.
As this decorative light, there is a decorative light of a type that uses a transformer (or adapter) to lower the voltage (Patent Document 1). This lowers the power consumption by lowering the voltage from the power supply, does not affect the human body against leakage, etc., and the supply voltage varies from country to country (for example, the supply voltage is 100V in Japan, Europe The supply voltage is 220 to 240V, the supply voltage is 220V in Hong Kong, and the supply voltage is 120V in the United States. .
However, in this type of decoration light, the transformer (or adapter) is required in addition to the light blinker that controls the blinking of lights such as miniature bulbs and LED lights. The construction and installation work becomes complicated, and there is a problem that it is necessary to transport and store the transformer (or adapter) and the light blinker.
In addition, there has been a power supply for reducing the voltage from the power supply conventionally, but there is no power supply integrated with the light flasher, and the low-voltage power supply has a hole for heat dissipation. Since it is necessary to provide etc., when it installs outdoors, since rainwater infiltrates, it cannot use outdoors.
In addition, the power supply and the light flasher can be integrated in the same case body. However, in this case, the noise generated by the light flasher circulates to the power supply, and noise that restricts electromagnetic interference. It is difficult to pass the regulation (EMI regulation), and the transformer for voltage conversion is large, so it cannot be made compact.

Furthermore, the present invention can provide a waterproof effect because the case body can be sealed, thereby having an excellent effect that it can be used outdoors without worrying about rainwater or the like.

  Examples of the best mode for carrying out the invention are shown below.

1 and 2 show an embodiment of an integrated low voltage power supply for a decorative light according to the present invention.
FIG. 2 shows an overall view of a decorative light 12 using the integrated low voltage power supply 10 of the decorative light of the present invention.
A large number of branch cords 16 are branched into the electric wire cords 14 constituting the light group 13 of the decoration lights 12, and light emitting diodes (Light Emitting Diodes) that consume less power and are less likely to break are used as light sources at the front ends of the branch cords 16. The LED light 18 is attached.
The decorative light integrated low-voltage power supply 10 is attached to the base end portion 14 </ b> A of the wire cord 14 via a connector 19.
The case main body 20 of the decorative light integrated low-voltage power supply 10 is formed of a synthetic resin material in a box shape and can be sealed. A lid 20B is attached to the main body 20A of the case main body 20 in a sealed state.
FIG. 1 shows a block diagram of an integrated low voltage power supply 10 for the decorative light. ACin (L) 22 and ACin (N) 24 connected to a plug 21 (see FIG. 2) to be inserted into the power source are provided on the left side surface 20C of the case main body 20 of the decorative low-voltage power supply 10. ing.
The ACin (L) 22 is connected to a high performance noise filter 28 via a fuse 26. The ACin (N) 24 is directly connected to the noise filter 28. The noise filter 28 prevents noise generated by a light blinker, which will be described later, from entering the power supply and prevents noise from entering from the power supply.
The noise filter 28 is connected to the first rectifier 30. The first rectifier 30 is a rectifier that does not rectify the voltage from the supply power supply at once but rectifies the voltage gradually.
The first rectifier 30 is connected to a switching device 32. The switching device 32 includes a controller 34 and an oscillator 36. The switching device 32 has a function of turning on and off the power.
The switching device 32 is connected to the transformer device 40. The transformer device 40 has a function of converting the flowing AC voltage into a constant voltage. In the present invention, by using the LED light 18 with low power consumption, the heat generated when the transformer device 40 converts the voltage to a constant voltage can be further suppressed.
The transformer device 40 is connected to a second rectifier 42. The second rectifier 42 has a function of changing the flowing alternating current to direct current and smoothing the voltage.
The second rectifier 42 is connected to a regulator 44. The regulator 44 has a function of further adjusting the current rectified by the second rectifier 42. A cord 46 is connected to the regulator 44 so that a DC voltage of 24 volts is output.
The regulator 44 is connected to a light flasher 50 (eight types of flashing). The light flasher 50 is a controller that controls the flashing of the LED light 18. The light flasher 50 is connected to a switch button 52 attached to the case body 20 and is operated by the switch button 52.
The light flasher 50 is connected to the first channel 56, the second channel 58, the third channel 60, and the fourth channel 62 through the transistor 54.
The first channel 56 and the second channel 58 are used when using the normally extendable type light group 13, and the third channel 60 and the fourth channel 62 are used when using the complete type light group 13. To be used.
In this embodiment, the first channel 56 and the second channel 58 are used. As shown in FIG. 2, the cord 46, the first channel cord 56, and the second channel cord 58 are connected to the connector 19. And connected to the electric wire cord 14 of the decoration light 12.

Next, the operation of the decorative low voltage power supply 10 of the decorative light according to the embodiment will be described.
The decorative low-voltage power supply 10 has a built-in light flasher 50 that controls the blinking of the LED light 18 and the function of changing the AC voltage to a direct current while keeping the voltage constant.
Therefore, since the increase in the number of parts can be suppressed and the weight can be reduced and the size can be reduced, the installation work when the decoration light device 12 is attached to a tree or a Christmas tree can be easily performed and the decoration light is integrated. The low voltage power supply 10 can be easily transported and stored.
In addition, since the decorative light integrated low-voltage power supply 10 is provided with a noise filter 28, the noise generated by the light flasher 50 is prevented from flowing into the supply power supply, and the noise enters the supply power supply. Can also be prevented. Thereby, the noise regulation (EMI regulation) which regulates electromagnetic interference can be passed.
Furthermore, since the heat generated from the transformer device 40 can be suppressed by using the transformer device 40 having the above configuration and the LED light 18 with low power consumption, the case body 20 can be sealed and waterproof (international waterproof protection class). : IPX44 can be acquired). Therefore, even if the decorative light integrated low-voltage power supply 10 is placed outdoors, it is possible to prevent rain, snow, etc. from entering the inside of the case body 20, so that the decorative light integrated low-voltage power supply 10 can be used outdoors. Can be used.

  In addition, although the example which used the LED light 18 with little power consumption as a light was shown in the Example, of course, a light is not necessarily limited to the LED light 18. FIG.

It is a block diagram of the integrated low voltage power supply of the decoration light of an Example. It is a schematic perspective view of the decoration light using the integrated low voltage power supply of the decoration light of an Example.
