Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus suitable for illuminating a local area such as a table lamp.

[0002]

2. Description of the Related Art Conventionally, as a lighting fixture for illuminating a local area, there is a desk lamp using a fluorescent lamp or an incandescent lamp as a light source. As an example of a table stand, for example, a column is erected from a stand base, an upper half of the column is bendable, and a head including a shade is provided at a tip of the column, and a fluorescent lamp is provided in the shade. Or an incandescent lamp is mounted so as to be lit, and a power cord having a plug at the tip is drawn from the stand base.

[0003] Illumination light from a fluorescent lamp or an incandescent lamp, which serves as a light source for a table lamp, has a high light amount,
Since it has a characteristic of omnidirectionality of 60 degrees, when it is used as a lighting fixture, the illuminating light is controlled in a required direction by providing a reflector in a shade or the like.

[0004] The table lamp as described above has a high light quantity, and is effective for illuminating a required local area or for enhancing the illuminating of a local area, for example, when working on a desk. Therefore, it can be cited as a typical example of a lighting fixture that illuminates a local area.

[0005]

However, the illumination light of incandescent lamps and fluorescent lamps contains illumination light that cannot be controlled and is wasted, and the conversion ratio of electric power to light is low, resulting in inefficiency. There is also a problem that the amount of heat generated sometimes is high and the life of the light source is short. In addition, there is a strong social demand for eye-friendly lighting that prevents diffused light from directly entering the eyes.

The place where the above-mentioned table stand can be used is limited to a place where a power outlet into which a plug is inserted is provided close to the place, and it is temporarily connected to a power supply through a separate wiring cord. Even if it is used, the distance between the power outlet and the place where the table lamp can be used is naturally limited, and connection work using a separate wiring cord is troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides an efficient and long-lasting and easy-to-eye illumination. In addition, the present invention provides good localization in various places where there is no power outlet. An object of the present invention is to provide a lighting device capable of lighting an area.

[0008]

According to the present invention, there is provided a lighting apparatus comprising: a plurality of LEDs arranged on a base so as to be lit and directed in a predetermined direction; a general-purpose terminal for obtaining a current supplied to the LEDs; A switch for controlling supply of the current obtained from the general-purpose terminal to the LED.
Since the luminaire uses an LED having a predetermined directivity as a light source, efficient and long-life and easy-to-eye illumination can be performed, and a current for lighting the LED is obtained through a general-purpose terminal, so that a notebook computer is used. The power source can be obtained also from the above, etc., and it has a high versatility that can illuminate a good local area in various places where there is no power outlet. In this case, since the power consumption of the LED is extremely small, even if the current is obtained from a notebook computer or the like, both the lighting fixture and the notebook computer operate normally and for a long time.

Further, in the above-mentioned lighting equipment, the base is supported via a support portion made of a flexible tube having a predetermined hardness. Since the base is supported by the flexible tube having a predetermined hardness, it is easy to change the illumination direction as needed.

Further, in the above-mentioned lighting equipment, it is characterized in that the lighting equipment is fixed to a required portion by a holding mechanism. By fixing the lighting fixture by the holding mechanism, the lighting fixture can be easily detachably attached to a desired place.

Further, the lighting fixture of the present invention comprises an LED provided in the vicinity of the distal end of a supporting portion made of a flexible tube having a predetermined hardness, a general-purpose terminal for obtaining a current supplied to the LED, and a general-purpose terminal for obtaining a current supplied to the LED. A switch for controlling supply of the current obtained from the terminal to the LED. By arranging the LED near the distal end of the flexible tube having a predetermined hardness, it is possible to easily change the illumination direction in a more localized area as needed.

Further, in the above-mentioned lighting equipment, the general-purpose terminal is a USB terminal. Since the USB terminal is widely used in personal computers, game machines, portable terminals, and other electric devices, the versatility of the lighting fixture of the present invention can be improved by using the USB terminal as a general-purpose terminal. .
