The present invention relates to a light bulb used to light a light on various memorial days, such as a temple hall or a Buddha's day, and more specifically, to the front of a printed circuit board (PCB). Install a plurality of light emitting diodes (LEDs) that consume less power and reduce the risk of fire due to overheating, and use a capacitor and a diode behind the printed circuit board. It is installed by connecting a plurality of light emitting diodes with less power consumption than a conventional bulb, and there is no risk of fire due to overheating of the bulb, and at the same time, it is possible to reduce production cost and maintenance cost.

In general, lanterns are a way of offering to the Buddha by saying that they light up the lanterns. I mean to light a fire).

Therefore, these lanterns are installed at regular intervals around temples and on roads to commemorate the day of Buddha and other Buddhist events, and for several days, especially for all those who attend during the event, the lights are lit.

In addition, the structure of the lantern is simply connected to the power supply at regular intervals to the main wire, the socket is attached to the bottom of the power supply is installed so that the light bulbs, such as incandescent lamps are combined and fixed, especially manufactured in various shapes and colors The lotus-shaped lantern case is fixed together with the bulb to illuminate the light.

However, these lanterns generally consume a lot of power because many light bulbs are lit for a long time during the boarding period, and there is a danger of fire due to overheating of the bulb.

Therefore, in order to solve the above problems, even if the lights are turned on for several days to several hundreds or thousands of lanterns, the power consumption is low, the maintenance cost and production cost are low, and at the same time, the risk of fire due to the heating of the lights An object of the present invention is to provide a light bulb without a lamp.

In addition, in order to achieve the above object of the present invention, instead of the conventional high power consumption and the high risk of fire, a plurality of light emitting diodes, which are low in maintenance and repair costs, have a resistance to a printed circuit board equipped with a rectifier and a capacitor. It is connected and installed in series, it is characterized in that it is inserted into the inner part of the main body with a connecting portion and fixed together with the protective cover.

Hereinafter, a preferred embodiment of the present invention with reference to the accompanying drawings in detail as follows. First, in describing each of the drawings, the same components have the same reference numerals as much as possible even though they are shown in different drawings.

1 is a view showing the external appearance of a light bulb for a light bulb according to the present invention, Figure 2 shows an exploded state of a light bulb for light bulb according to the present invention, Figure 3 shows an embodiment according to the present invention and Figure 4 is The circuit state of the present invention is shown.

As shown, the present invention is connected to the socket (11) installed in the lamp case (10) for supplying power, and rectifying circuit for rectifying the AC power supplied through the connection to make a DC power source A light emitting diode 25 emitting bright light is connected to the printed circuit board 20 and a protective cover 30 which protects the printed circuit board is integrated with the connection part 15. In the light bulb for fixing to the formed main body 16,

The printed circuit board 20 is installed by connecting a resistor (R1) and a capacitor (C1) in parallel in order to lower the size of the AC power supplied through the connecting portion 15 and to prevent leakage current, and then the AC voltage It is characterized in that the rectifier (BR1) for rectifying the DC voltage, the resistor (R2) for reducing the magnitude of the DC voltage passed through the rectifier, and the light emitting diodes 25 for emitting a bright light is connected.

That is, after changing to the AC power DC power source in the existing rectifier circuit 22, the electrolytic capacitor which smoothes the DC power supply is removed, and the rectifier BR1 and the resistor R2 are directly connected, and then the light emitting diode 25 ).

In the case where the conventional rectifier circuit 22 is used, an electrolytic capacitor and a resistor R2 are connected in parallel in order to make a stable DC power supply below a predetermined level. However, when only the light emitting diode 25 is used, a predetermined level is used. It requires the following reduced power supply, but does not require a smoothed direct current power source with the pulses removed. In other words, it does not require a constant-size DC power supply that is convenient to control, such as street lamps or other electrical appliances. Instead, it is a light bulb used for events, which requires high maintenance and repair costs or maintains a constant brightness to illuminate the surroundings. Not what you want

 Therefore, the electrolytic capacitor installed in order to remove the pulsation of the existing rectified DC power supply directly connected in series with a resistor (R1) and a rectifier (BR1) in conjunction with a plurality of light emitting diodes 25 to illuminate the fire. It is characterized by being constructed.

In addition, the protective cover 30 is attached to or detached from the main body, and at the same time protects the light emitting diodes 25 from the impact from the outside, or part of the printed circuit board or cable rusted by rain or dew, or It is configured to engage with the main body to prevent short circuit.

5 and 6 show a perspective view and a circuit diagram respectively showing an exploded state showing another embodiment according to the present.

The light emitting diodes 25 installed on the circuit as shown in the figure can be installed in series or in parallel, and at the same time, the light emitting diodes installed on the printed circuit board 20 are also inserted into a constant groove 16 through which current flows, and in parallel. It is characterized by being installed side by side fixed.

That is, when the groove 26 having a constant depth is made long in the middle of the conductive line to which the conventional resistor R2 and the light emitting diode 25 are connected, no current flows. At this time, when the light emitting diodes 25 are inserted into and fixed in the pair of grooves 26 or holes, current flows to light the light emitting diodes. Here, when the light emitting diode is fixed by inserting another light emitting diode into the same groove in which the light emitting diode is fixed, a plurality of light emitting diodes 25 are connected to one groove 26 in parallel to illuminate light side by side.

Referring to the drawings the operation and operation of the present invention light bulb for light bulbs are as follows.

First of all, on the day of Buddha or other Buddhist events, a lantern case 10 is installed in a street around a street or a temple, and the lamp bulb of the present invention is installed in a socket 11 located in the lantern case 10. The connection part 15 of is screwed and installed.

Then, an AC voltage of AC 220v coming from the outside is applied to the printed circuit board 20 through the connection part 15 of the lamp bulb of the present invention, and the AC voltage of the applied AC 220v is a plurality of light emitting diodes ( The low voltage is dropped by the resistor R1 and the capacitor C1 so as to turn on the light.

The AC voltage dropped below a predetermined level is rectified and rectified by the rectifier BR1 and converted into a DC voltage below a predetermined level.

In addition, the rectified DC voltage rectified through the rectifier BR1 is connected in series with a resistor, and then lowered to a low voltage below a predetermined level, and then connected to a plurality of light emitting diodes 25 connected in series or in parallel to reveal bright light. Is to be given.

Therefore, the light bulb for the light bulb of the present invention is installed using a light emitting diode in place of an incandescent lamp and a bulb mounted in a conventional lantern case, so that there is no risk of fire due to the heat generation of the bulb, and at the same time, power consumption is low, which can reduce maintenance costs. It works.

In addition, the light bulb of the present invention can reduce the production cost and obtain an economic benefit by removing the electrolytic capacitor that has been used to smooth the existing rectified DC voltage.
