Description

Portable rotatable lighting technology

The present invention relates to a lighting device, and more particularly to a rotatable lighting lamp. Background technique

At present, portable lighting fixtures used in people's daily life, such as flashlights, generally have a fixed illumination direction. When lighting is required in different places, the illumination can only be illuminated by the user's arm to achieve illumination of different places. In some cases, such as repairing a car in the wild at night, the user needs to hold the light in one hand to work, or need to cooperate with many people to work, causing great inconvenience to the use. In order to solve this problem, the patent document CN2295109Y discloses a universal illuminating lamp, as shown in FIG. 1, which has a corresponding structure for adjusting an arbitrary illumination angle and height, by an adjusting nut 100, a spring 200, a pole 300, and illumination. The lamp 400, the pole snap ring 500, the fastening bolt 600, the screw 700, the illumination snap ring 800, the hanging chain 900 and the controllable permanent magnet base 1000 are formed, which solves the problem that the existing illumination lamp cannot adjust the illumination angle and height arbitrarily. The problem is to achieve an adjustable illumination angle of 0 ~ 3 60 ° ° and to adjust the height of any lighting. It can be seen that the universal illuminator disclosed in this document is only a combination of an illuminating lamp and a rotating device, and is not convenient to carry.

In addition, the patent document CN2766140Y discloses a universal repair illumination lamp, which is composed of a lamp cap 100, a battery 200, an upper socket 500 and a lower socket 300. The upper socket 500 is provided with a rotating shaft 600, and the rotating shaft 600 is inserted in the lower socket. 300 is positioned by the spring card 700 of the lower socket 300; the base 100 is hinged to the upper socket 500 by bolts 900, and the bulb on the base 100 is a light-emitting diode (LED). Although the universal repair illumination lamp realizes the universal rotation of the lamp head, the structure is complicated and bulky, and is mainly suitable for night car maintenance, which is inconvenient for people to use in daily life, and has only the illumination function.
