Lamp

Abstract

The invention discloses a lamp. The lamp comprises a base, a lamp holder, a lamp arm which is provided with a hollow structure and connected between the base and the lamp holder, a first rotating shaft mechanism located between the lamp arm and the lamp holder and / or between the lamp arm and the base, and a connecting wire, wherein the first rotating shaft mechanism comprises a first rotating shaft part with a penetrating space, a first rotating structure and a first friction structure, a first fixing support with a first wire casing, and a first rotating support with a second wire casing; thefirst rotating support is connected with the first fixing support through the first rotating shaft, and the penetrating space is located between the first rotating structure and the first friction structure; or, the penetrating space surrounds the first rotating structure or the first friction structure; the connecting wire penetrates through the first wire casing, the penetrating space, the second wire casing and the hollow region of the lamp arm so that the lamp holder can be electrically connected with the base. While internal wiring can be achieved, the size of the first rotating shaft part is reduced, and torsion and service life are ensured.

Description

technical field [0001] The present disclosure relates to the technical field of lighting, in particular to a lamp. Background technique [0002] In the prior art, the multi-axis desk lamp has been favored by users because of its advantage that the lighting direction can be adjusted. In the design of multi-axis table lamps, based on the consideration of industrial aesthetics and neatness of wiring, it is often necessary to design internal wiring while ensuring the size of the shaft. [0003] Since the torque of the rotating shaft is generated by the friction in the structure of the rotating shaft, the magnitude of the friction is closely related to the friction area, but the existing internal wiring design will cause the loss of the friction area. Based on this, if the internal wiring is to be implemented, the overall size of the shaft will be larger, which is contrary to the concept of industrial design, but if the size of the shaft is to be ensured, it will have a negative...

Problems solved by technology

[0003] Since the torque of the rotating shaft is generated by the friction in the structure of the rotating shaft, the magnitude of the friction is closely related to the friction area, but the existing internal wiring design will cause the loss of the friction area

Based on this, if the internal wiring is to be implemented, the overall size of the shaft will be larger, which is contrary to the concept of industrial design, but if the size of the shaft is to be ensured, it will have a negative impact on the torque of the shaft, and at the same time shorten the life of the shaft Can not guarantee
