2. Description of the Related Art In a lighting apparatus that imitates the shape of a flame such as a candle, conventionally, a flame is simulated by incorporating a light source in a light-transmitting cover in the shape of a flame.

[0003]

However, the conventional method has a poor appearance because the light source can be seen through. In addition, there is a light source built in a single translucent cover and there is a circuit that creates fluctuations by blinking light, but it fully reproduces the image of a candle flame, such as lighting or blinking in the shape of a flame However, it was not suitable for use in applications where a flame could be seen up close as a directing effect.

Accordingly, an object of the present invention is to provide a lighting device which can sufficiently reproduce an image of a flame even in an application which can be viewed up close, and can produce faint light.

[0005]

According to a first aspect of the present invention, there is provided a lighting device comprising: a light source which is electrically lit; In a lighting device provided with a light-transmitting cover, the light-transmitting cover includes a first cover that covers the light source and is made of a high-diffusive light-transmitting member, and is made of a light-diffusing transparent member that covers the first cover. And a second cover.

As described above, the translucent cover includes the first cover that covers the light source and is made of a highly diffusive translucent member, and the second cover that covers the first cover and is made of a diffusible transparent member. Therefore, the first cover can prevent the light source from being seen through, and the first and second covers produce a double flame of flame. For this reason, it is possible to provide a safe and indelible lighting device having an image of a candle even in an application that can be seen up close, and it can be used in a space such as a restaurant where the atmosphere is important.

According to a second aspect of the present invention, in the first aspect, the first cover is milky white, and the second cover is textured. Thus, since the first cover is milky white and the second cover is textured, it is possible to prevent the light source from being seen through by the first cover, and to produce faint light. The second cover also blurs the shape of the flame, creating a real flame instability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a longitudinal sectional view of a flame-shaped lighting device according to an embodiment of the present invention, FIG. 2 is a perspective view showing the appearance of the lighting device according to the embodiment of the present invention, and FIG. FIG. 5 is an explanatory diagram of an operation of turning on and off the power.

1 and 2, reference numeral 1 denotes an electrically lit light source, 2 denotes a translucent cover, 3 denotes a first cover,
Is a second cover, 5 is a lamp, 6 is a lighting circuit, 7 is a switch, and 8 is a dry battery or a storage battery.

The light-transmitting cover 2 has a light source 1 built therein and is formed in a substantially candle flame shape. The light-transmitting cover 2 covers the light source 1 and is made of a highly diffusive light-transmitting member. A second cover 4 which covers the cover 3 and is made of a diffusible transparent member. In this case, the material of the first cover 3 is made of a milky white resin material (milky resin), and the second cover 4 is made of a flame-shaped and nearly transparent resin material (transparent resin). It has been textured (erased).

The light source 1 uses an LED. LED
The size can be reduced by using. LED
The color of the flame can be adjusted by setting the LED to blue or red, which can be further downsized by arranging the LEDs vertically. In this embodiment, LE
Although D is used, incandescent mini-spheres are also possible. The lamp body 5 has a cylindrical shape resembling a Western candle,
A lighting circuit 6, a storage battery 8, and the like are built in.

The lighting circuit 6 is used for lighting the light source 1. By incorporating a fluctuation circuit in the lighting circuit 6 that produces fluctuation by blinking light, the contraction of the flame can be reproduced more precisely. That is, when the light emission of the light source 1 is suppressed by the fluctuation, the light of the first cover 3 becomes weak,
Light does not reach every corner of the cover. At this time, when the first cover 3 is viewed through the second cover 4, the first cover 3 appears to be blurred due to diffusion of the second cover 4.
The darkened part of the image becomes invisible. On this occasion,
Since the shape of the first cover 3 appears to change, the flame appears to fluctuate.

The switch 7 has a contact 9 directly attached to the lighting circuit 6. The lighting circuit 6 is fixed to the translucent cover 2, and as shown in FIG. 3, by operating and rotating the second cover 4, the contact 1 extending from the opposite side of the storage battery 8 is rotated.
The power can be turned on and off by making contact or non-contact with zero. With this structure, ON-O
A structure that does not allow FF is made possible.

Further, by using the storage battery 8 and lighting it, it can be freely carried and used easily. Although the storage battery 8 is used in this embodiment, waste can be reduced by having a charging mechanism. In addition, in the case of fixed use at a Buddhist altar, a corridor, or the like, it is possible to eliminate the need to replace the power supply by incorporating an AC adapter.

As described above, according to this embodiment, the first cover 3 can prevent the light source 1 from being seen through, and can produce faint light. In addition, the second cover 4 can blur the shape of the flame and produce the actual instability of the flame. Further, by incorporating the fluctuation circuit in the lighting circuit 6, the contraction of the flame can be reproduced more precisely.

In general, in a lighting device imitating the shape of a candle, a switch for turning on and off the light is turned on and off by pressing a flame portion or a bottom surface so as not to impair the appearance. It may be easily erased by touching the user. In this embodiment, it is possible to provide an illuminating device having a built-in inexpensive switch that can be easily turned on and off as described above but is not accidentally erased and does not impair the appearance design.

The material of the first cover 3 may be glass or the like, and even if the material itself is not milky white, the same effect can be obtained by painting or the like. Further, the color of the flame can be adjusted by using a color other than milky white such as blue or red. Similarly, the material of the second cover 4 may be glass or the like, and the same effect can be obtained by treating the surface of the cover with a diffusing surface treatment such as painting. Surface treatment is possible not only on the outer surface but also on both surfaces. When the surface treatment is not performed, the same effect can be obtained even if a material having high transmission and high diffusion is used.
