Problems solved by technology

In the case of contacting or pressing the above-mentioned switch, it is easier to operate the switch with the pulp of the finger, so it is necessary to twist the wrist near the lighting device to make the pulp of the finger touch the switch, and the operation of the switch is slightly difficult. The problem
On the other hand, in the lighting device such as Patent Document 2, since the above-mentioned switch is facingly arranged on the above-mentioned main body, the above-mentioned switch can be naturally operated with the pad of a finger, but the above-mentioned main body is electrically connected to the lampshade, so the above-mentioned main body and the flexible The condom cannot be separated
Therefore, there is a problem that the package size becomes large
In addition, in the lighting device such as Patent Document 3, since the above-mentioned switch is installed obliquely upward on the above-mentioned desk lamp mounting part, the above-mentioned switch can be naturally operated with the fingertips, but the above-mentioned desk lamp mounting part protrudes forward. So there is the problem of poor appearance

Abstract

The present invention provides a lighting device which can be easily operated and need not thicken an arm portion than necessary. An electric table lamp (1) as a lighting device is provided with a lamp fixture (4) at the front end of the arm portion (3), a hole portion (8) is formed on a strut portion (5) for forming the arm portion and passes through along anterior-to-posterior, a contact mode sensor (9) is arranged at the inner peripheral surface (8A) of the hole portion and is used as a switch, thereby inserting fingers from an opening portion (8B) at the front of the hole portion, and operating the contact mode sensor in the hole portion, as as to lighten or quench the lamp fixture. In addition, the contact mode sensor can be natually touched by the finger pulp by arranging the contactmode sensor along the inner peripheral surface of the hole portion. Moreover, because the contact mode sensor is arranged on the hole portion, even the contact mode sensor is made into a constructionnot toward the positive surface, the strut portion need not be thickened than necessary.

Description
