Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device in the form of a candle or an incense stick for use in a shrine or a Buddhist altar, and a lighting device such as a mood lighting lamp for a dining table or the like.

[0002]

2. Description of the Related Art Heretofore, there has been known a lighting device for lighting a miniature bulb using a 100 V AC power supply or a battery as a power source, instead of a lighting device for lighting a candle by lighting.

[0003]

However, according to this means, when the lamp is inadvertently knocked down or vibration occurs during handling, etc., the miniature bulb is damaged, and it takes time to replace the miniature bulb. In addition, there is a problem in that if the power is turned on continuously for a long time due to forgetting to turn off the power, power is wasted wastefully, and especially when the power source is a battery, the amount of stored power is reduced and the battery must be replaced. When the power supply is 100V AC current,
If left unintentionally turned on, there is a danger that short-circuiting or ignition may occur due to heat generation, which may cause a fire.

Accordingly, the present invention has been made to solve the above-mentioned conventional drawbacks, and can be used for a long time with low power consumption, and can significantly extend the useful life of the luminous body. It is an object of the present invention to provide a lighting device that can be used safely without the danger of fire caused by the lighting device.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, the lighting device according to the present invention includes a columnar body 2 provided with an LED light emitting body 1 at a tip thereof, and a base 5 for detachably holding the columnar body 2, and the base 5 has an interior. LED having a battery storage part 4 for storing the dry battery 3 and powered by the dry battery 3
An electric circuit is provided to the light-emitting body 1, and a first member which operates when the columnar body 2 is attached to the base 5 in the electric circuit is activated.
LED switch 1 for a set time via switch S1
Is built in.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The timer switch 6 may be of a type capable of freely setting the operation time, but it is preferable to use a timer IC which operates for a preset time, for example, 10 minutes. Thereby, compactness and cost reduction can be achieved. Further, it is preferable that the periphery of the LED light-emitting body 1 provided at the tip of the columnar body 2 is covered with a light-transmitting coating 7 made of resin or glass in the form of a flame, for example. As a result, the outer shape of the lighting device is beautifully finished, and the LED light emitter 1 is protected, and the service life can be extended.

It is preferable that a second switch S2 for manually turning on the timer 6 be provided on the base 5. As a result, when the LED light emitter 1 is turned off after the set time of the timer 6 ends and the LED light emitter 1 is to be turned on again, the second switch S2 is turned on by a fingertip to operate the timer 6 again. By operating, the LED light emitter 1 can be turned on for a set time.

[0008]

FIG. 1 is a sectional view showing an embodiment of the present invention.
FIG. 2 is a block diagram showing the electric circuit. In this embodiment, the lamp is embodied as a candle-shaped lamp for Shinto and Buddha, and a candle-shaped pillar 2 having an LED light-emitting body 1 at a tip thereof, and a base 5 for detachably holding the pillar 2. And The base 5 includes a battery storage unit 4 for storing the dry batteries 3 therein, and an electric circuit for the LED luminous body 1 powered by the dry batteries 3 is provided.

The columnar body 2 is formed such that when it is inserted into the insertion hole 5a of the base 5, the LED luminous body 1 and the dry cell 3 are electrically connected.

[0010] Further, an LED luminous body 1 powered by a dry cell 3
A timer 6 for turning on the LED light emitter 1 for a set time via a first switch S1 which is activated by contact when the columnar body 2 is attached to the base 5 is incorporated in the electric circuit. The first switch S1 is preferably provided near the insertion hole 5a into which the light emitter 1 is inserted as shown in FIG.
Further, a second switch S2 for manually turning on the timer 6 again when the LED illuminator 1 is turned off after the set time of the timer 6 is provided on the surface of the base 5.
Reference numeral 10 denotes a lid for closing the battery storage unit 4.

In the above configuration, when the candle-shaped column 2 is inserted into the insertion hole 5a of the base 5 and attached, the first switch S1 comes into contact with the base of the column 2 and is turned on. As a result, the timer 6 is turned on to turn on the LED light emitter 1 for a set time, for example, 10 minutes. After the set time of the timer 6 is completed and the LED light emitter 1 is turned off, if it is desired to turn on the LED light emitter 1 again, the second switch S2 may be pressed with a fingertip. Thereby, the timer 6 is operated again, and the LED light emitter 1 can be turned on for the set time. Of course, by pulling out the column 2 from the insertion hole 5a and inserting it again,
The luminous body 1 can be turned on again. In addition, since the power consumption of the LED light emitter 1 during lighting is extremely low, even a single dry battery can be used for a long time. However, the LED is not limited to 1.5V, but 3V
In this case, the batteries may be used by connecting them in series.

In the present invention, the second switch S2 in the above embodiment can be omitted. In this case, LED
When it is desired to turn off the light-emitting body 1 and turn it on again, the columnar body 2 may be pulled out from the insertion hole 5a and inserted again.

Although the embodiment which is considered to be representative of the present invention has been described above, the present invention is not necessarily limited to this embodiment. For example, it is also possible to form two or more columnar bodies 2 each having the LED luminous body 1 at the tip end. The form of the columnar body 2 is not limited to a candle, but may be a form of incense stick or a mood lighting lamp used at a dining table or the like. In addition, the timer is not limited to the one with the low time setting, and may be implemented as one with a variable time setting. In addition, the present invention has the above-mentioned constitutional requirements, achieves the object of the present invention, and can be appropriately modified and implemented within the scope of the following effects.

[0014]

The lighting device according to the present invention is constructed as described above, so that unnecessary power consumption due to forgetting to turn off can be eliminated, and the power consumption at the time of lighting can be eliminated because the luminous body is formed by the LED. And the service life can be greatly extended compared to miniature bulbs. Further, since the calorific value of the luminous body is extremely low, there are various remarkable effects such that there is no danger of fire or the like due to heat generation even if the lighting device is accidentally turned over and left as it is, and the safety is high.
