However, in the conventional LED lighting device for hanging on the neck, if the irradiation direction of the LED cannot be adjusted, it is necessary to hold the LED holding part in the hand and illuminate the target direction, and the one having the irradiation direction adjusting function. However, it was inconvenient because the irradiation direction had to be readjusted each time the power was turned on and off. In addition, the usage is limited, such as being used only for the purpose of illuminating the outside environment. And it is mainly used to wear it around the neck, but when the user leans forward, the lighting device sways around his chest, and it is difficult to use because the LED is not illuminated at the target. Since the length of the string portion cannot be adjusted, it cannot be used according to the body shape and purpose of the person.
The present invention has been made in view of the above point, and its main purpose is to change the irradiation direction and method of the LED, so that the LED lighting device for a neck hanging can be used according to the body shape and purpose of the person. Is to provide.

In order to solve the conventional problems, a battery as a power source, a main body that holds the battery, the LED, and a connection terminal in a built-in manner, and a neck strap portion of a soft material are provided, and the neck strap portion is provided. Has a box-like shape into which the main body can be inserted and has a first locking portion on the inner wall, and the main body has a second locking portion facing the first locking portion. By fitting the second locking portion with the first locking portion, the main body is locked to the neck hanging string portion, and the main body can rotate about the second locking portion as an axis. did.
Moreover, the main body insertion direction of the neck hanging cord portion into the box shape is a direction in which the LED irradiation surface of the main body is directed toward the box-shaped opening side of the neck hanging cord portion, and the LED irradiation surface of the main body. Can be mounted either in the direction opposite to the box-shaped opening of the neck strap .

According to the present invention, the protrusions present on the left and right of the outer surface of the main body are engaged with the recesses provided so as to face the inside of the box-shaped wall at the ends of the neck-hanging cord portions, thereby being locked. In addition to the above, the convex projection serves as an axis, and the main body is allowed to rotate, so that it is possible to obtain the neck-mounted LED lighting device capable of adjusting the irradiation direction. The terminal connection, that is, the operation of turning the power on and off is completed inside the main body, and is configured not to be related to the rotation operation of the main body. Therefore, the power is turned on and off repeatedly while maintaining the irradiation direction of the LED. It can be used.

Further, the main body can be inserted into the box shape of the neck hanging cord portion so that the LED irradiation surface of the main body can be mounted in a direction opposite to the box shape opening of the neck hanging cord portion. As a result, it is possible to obtain light that illuminates the entire box-shaped portion faintly from the inside of the necklace, and it is possible to expand the usage such as indirect lighting in a tent during camping.

The box-shaped outer surface of the necklace string portion is provided with a U-shaped clip so that it can be fixed to clothes or the like, and the neck-mounted LED lighting device can be prevented from swinging around the chest. In addition, since one string of necklace has a plurality of spherical bulges at appropriate intervals, it can be adjusted to an appropriate length and is easy to use. LED lighting device for use.
