A variable resistor 6 is connected to a power supply in series with the incandescent lamp 5 and in parallel with the fluorescent lamp 4. A switch 7 is connected between the fluorescent lamp 4 and the incandescent lamp 5 and the power supply.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a desk lamp suitable for reading and the like.

[0002]

[Prior art]

 As a conventional desk lamp, one using a fluorescent lamp or one using an incandescent lamp is generally well known. Fluorescent light has the advantage of giving a bright feeling, and incandescent light has the advantage of giving a soft and warm feeling.

[0003]

[Problems to be solved by the invention]

 However, the conventional desk lamp using a fluorescent lamp has a problem that the light flickers and the light gives a cold feeling. In addition, a conventional desk lamp using an incandescent lamp has a problem in that the light has a yellow tint and feels lacking in brightness.

The present invention has been made in view of such conventional problems, and the light has both the bright feeling of a fluorescent lamp and the soft and warm feeling of an incandescent lamp, and the flicker of the light of the fluorescent lamp. The purpose is to provide an electric stand that reduces the feeling of coldness, the yellowness of incandescent light and the lack of brightness.

[0005]

[Means for Solving the Problems]

 To achieve the above object, a desk lamp according to the present invention includes a column, an umbrella, a fluorescent lamp, an incandescent lamp, a variable resistor, and a switch; the umbrella is attached to the column. The fluorescent lamp and the incandescent lamp are detachably mounted inside the umbrella section and connected to a power source in parallel with each other; the variable resistor is connected in series to the incandescent lamp and to a power source in parallel to the fluorescent lamp. Connected; wherein the switch is connected between the fluorescent lamp and the incandescent lamp and a power supply.

[0006] The support may be fixed to the base or to a mounting bracket. Preferably, the variable resistor and the switch consist of an integral part. The power source is preferably a household 100V power source.

In the desk lamp according to the present invention, when the switch is turned on, the fluorescent lamp and the incandescent lamp are turned on. The combined light of fluorescent light and incandescent light has both the bright feeling of fluorescent light and the soft and warm feeling of incandescent light, and the flickering and cold feeling of fluorescent light, and the light of incandescent light. Cancel and reduce the yellowness and lack of brightness. In addition, by operating the variable resistor, the brightness of the light of the incandescent lamp can be adjusted according to the taste and the type of work, and the harmony with the light of the fluorescent lamp can be arbitrarily achieved.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention. As shown in FIGS. 1 to 5, the desk lamp 1 includes a column 2, an umbrella section 3, a fluorescent lamp 4, an incandescent lamp 5, a variable resistor 6, and a switch 7.

As shown in FIG. 2, the column 2 is fixed vertically to the base 8. The umbrella section 3 is attached to the column 2 with an arm 9. As shown in FIG. 3, the opening 3a of the umbrella portion 3 has a rectangular shape. The inner surface 3b of the umbrella portion 3 is mirror-finished. The fluorescent lamp 4 and the incandescent lamp 5 are detachably mounted inside the umbrella part 3. The fluorescent lamp 4 is, for example, a 27 W twin fluorescent lamp. The fluorescent lamp 4 is attached to the end 3 c opposite to the position of the arm 9. The incandescent lamp 5 is, for example, a 40 W krypton bulb. The incandescent lamp 5 is attached to the end 3 d on the side of the arm 9. As the fluorescent lamp 4 and the incandescent lamp 5, another wattage or another type may be used.

As shown in FIG. 1, the fluorescent lamp 4 and the incandescent lamp 5 are connected to a power supply 10 in parallel with each other. The power supply 10 is composed of a household 100V power supply, and is connected to an outlet with a plug. The variable resistor 6 is connected to a power supply 10 in series with the incandescent lamp 5 and in parallel with the fluorescent lamp 4. The switch 7 is connected between the fluorescent lamp 4 and the incandescent lamp 5 and the power supply 10. The switch 7 also serves as an operation unit of the variable resistor 6. As shown in FIGS. 4 and 5, the switch 7 is provided in the umbrella unit 3.

Next, the operation will be described. When the switch 7 is turned on, the fluorescent lamp 4 and the incandescent lamp 5 of the desk lamp 1 are turned on. The light obtained by combining the light of the fluorescent lamp 4 and the light of the incandescent lamp 5 has both the bright feeling of the fluorescent lamp 4 and the soft and warm feeling of the incandescent lamp 5, and the flickering of the light of the fluorescent lamp 4 It cancels out the feeling of coldness, the yellowness of the light of the incandescent lamp 5 and the feeling of lack of brightness. Further, by operating the variable resistor 6 with the switch 7, the brightness of the light of the incandescent lamp 5 can be adjusted according to the preference and the type of work, and the harmony with the light of the fluorescent lamp 4 can be arbitrarily adjusted. Can be planned. Since the light of the desk lamp 1 is in harmony with the light of the fluorescent lamp 4 and the light of the incandescent lamp 5, the eyes are less tiring and are optimal for reading.

[0012]

[Effect of the invention]

 According to the desk lamp of the present invention, a fluorescent lamp and an incandescent lamp are provided, and the brightness of the light of the incandescent lamp can be adjusted by the variable resistor. Combines the soft and warm feeling of incandescent light, reduces the flicker and coldness of fluorescent light, reduces the yellowness and lack of brightness of incandescent light, and balances fluorescent light with incandescent light. be able to.
