By doing so, the overall length is changed.

According to a fourteenth aspect of the present invention, in the spot illuminating device according to any one of the twelfth and thirteenth aspects, the plurality of LEDs are disposed inside the cylindrical body.

[0018]

According to the first aspect of the present invention, as described above, a lighting device using an LED as a light source for illuminating the inside of the cabinet is installed. The interior can be illuminated brightly, and therefore, when articles in and out of the cabinet are put in and out, or when predetermined operations are performed in the cabinet, such operations can be easily performed.

When the interior of the cabinet is illuminated, it is not necessary to illuminate the entire kitchen by illuminating the main lighting device of the kitchen when the purpose is to access articles in the cabinet or to work inside the cabinet. For example, even when it is necessary to get out of the cabinet and get out of the cabinet while sleeping at night, the main lighting device does not cause glare.

In the present invention, the light source of the lighting device is LE.
Since D is used, the power consumption is small, and the LED has a remarkably long life, so that there is no problem that the bulb needs to be periodically replaced as in the case of using a normal bulb. . Furthermore, since the LED is small, the entire lighting device can be made compact,
Therefore, when installing this in a cabinet, the lighting device does not occupy a large space, and the lighting device becomes largely protruded, which hinders access to articles in the cabinet and work in the cabinet. There is no inconvenience. Although a single LED can be used as a light source, a lighting device can be configured by using a plurality of LEDs. This applies to the following claims.

In the first aspect of the present invention, the lighting device can illuminate a deep portion of the cabinet. The inner part of the cabinet is particularly dark, and therefore, by illuminating the inner part, it becomes easier to access articles in the cabinet and to work inside the cabinet. In this case, the lighting device can be installed inside the cabinet and on any of the counter, back plate, side plate, bottom plate, and curtain plate of the cabinet.

In a third aspect of the present invention, an illuminating device using an LED as a light source is installed below the range hood to illuminate an area below the range hood. It is possible to illuminate brightly, and thus to illuminate brightly the range and the vicinity of the range where the illumination has been insufficient in the past, and it becomes easy to perform the work using the range. Further, in the lighting device of the third aspect, an LED is used as a light source.
The above advantages of the ED can be enjoyed.

According to the third aspect, the LEDs can be arranged in a plurality of planes, and the illumination light can be emitted from the LEDs in a plane (claim 4). Further, in this case, the illuminating device can be installed at the center of the lower end opening of the range hood and in a state where an annular gap for smoke exhaust is formed around the periphery (claim 5). In this way, the light sources can be arranged over a wide space, and the lower range can be illuminated more brightly.

Next, a lighting device using an LED as a light source for illuminating the inside of the grill on the front glass of the range grill is installed. The inside of the grill, which was not present, can be brightly illuminated, and the inside can be clearly understood. For example, the degree of grilling of fish can be easily understood from the outside, and cooking can be easily performed. Also in the sixth aspect, the LED is used as the light source of the lighting device, and therefore, the above-described advantages when the LED is used as the light source can be enjoyed.

According to a seventh aspect of the present invention, an illuminating device using an LED as a light source for irradiating illumination light toward a lower range is installed in a lower portion of an upper cabinet in a kitchen. The range and the surroundings of the range can be brightly illuminated, and work using the range becomes easier. Also, in the seventh aspect, an LED is used as a light source of the lighting device, and the above-mentioned advantages provided by the LED can be enjoyed.

According to another aspect of the present invention, there is provided an LED for irradiating illumination light to a faucet device below the upper cabinet.
And a lighting device using the light source as a light source.
In, since the faucet device can be partially illuminated brightly, the faucet device can be used under bright light, and the faucet device becomes easy to use.

Also, as described above, when the user wakes up while sleeping at night and uses the faucet device, the position of the faucet device can be known without any trouble without turning on the main lighting device for illuminating the entire room. Can be used without hindrance. Furthermore, since the LED is used as the light source of the illuminating device in claim 8, the above-mentioned advantages provided by the LED can be enjoyed.

According to a ninth aspect of the present invention, a movable microphone type (pen type) lighting device provided with a grip portion and an LED as a light source provided at the tip thereof is installed in equipment in a kitchen. By doing so, the microphone-type lighting device is taken out and the required portion is irradiated with illumination light, thereby improving the workability when using each equipment. In this case, the microphone-type lighting device may be connected to a power source with an electric cord, or the microphone-type lighting device may be provided with a power source such as a dry battery so that the microphone-type lighting device can be moved cordlessly. You can also.

Here, the microphone type lighting device can be installed in front of the range (claim 10). In this way, when it is desired to know the inside of the grill, the microphone-type lighting device can be taken out to easily illuminate the inside of the grill.

According to the eleventh aspect, a lighting device using an LED as a light source is installed in a head portion that constitutes a tip portion of a water discharge pipe of a faucet device and that can be drawn out together with a hose. When the bottom of the pot is washed while discharging water by pulling out the part with a hose, the bottom of the pot, which is likely to be dark, can be illuminated brightly, so that the degree of dirt can be clearly understood and the work such as pot washing can be performed well. Will be able to do it. Alternatively, when the head is pulled out together with the hose to wash the corner of the sink, the corner of the sink can be similarly brightly illuminated, so that the cleaning operation can be performed well.

The LED itself has a high directivity and is suitable as a light source for a spot lighting device. However, if the light from the LED is simply applied to the target portion as it is, when the distance to the target portion is long, the illumination light becomes too wide and the spot diameter of the spot light becomes too large, or Conversely, there is a disadvantage that the spot diameter becomes too small because the distance is too short.

Here, in the spot illuminating device according to the twelfth aspect, the LED is arranged inside the cylinder, the light from the LED is irradiated from the front end opening of the cylinder, and the length of the cylinder in the axial direction is variable. According to this spot lighting device,
By changing the axial length of the cylindrical body, the spot diameter of the spot light can be freely controlled, and the target portion can be irradiated with the spot light with the optimum spot diameter.

In this case, the cylindrical body has a double cylindrical structure of a first cylindrical member and a second cylindrical member, and the entire length is variable by sliding them relatively in the axial direction. (Claim 13). By doing so, the axial length of the cylindrical body can be easily adjusted to a desired length.

Further, a plurality of LEDs can be provided inside the cylindrical body. By arranging a plurality of LEDs inside the cylinder in this way, the spread of light by the LEDs themselves can be widened in advance as compared with the case where only one LED is arranged. By changing the axial length of the cylinder, it is possible to increase the adjustable range of the spot diameter.
