A slip-ring-free three-dimensional scanning laser lamp comprises a light guide cylinder assembly which is used for providing a light path and a channel of a laser beam; the spiral signal transmission assembly is arranged on the light guide cylinder assembly in a sleeving manner; the movement assembly is arranged at one end of the light guide cylinder assembly in a sleeving manner; the positioning assembly is used for ensuring movement and positioning of the movement assembly, and the positioning assembly is arranged at the bottom of the movement assembly. The spiral signal transmission assembly is used for transmitting electric signals, a contact sliding signal transmission mode of a conductive sliding ring is replaced, non-contact and non-sliding signal transmission is achieved, and the defect of sliding signal transmission is overcome; the system operation stability and reliability are improved, and the service life of the laser lamp can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of laser lamps, and more particularly, to a three-dimensional scanning laser lamp without a slip ring. Background technique [0002] At present, the three-dimensional scanning laser lamps mostly use conductive slip rings to realize circular motion and electrical signal transmission. An obvious disadvantage of this technology is that the conductive slip rings use the method of sliding contact between the static contact and the moving contact. The transmission of electrical signals requires relatively high wear resistance, corrosion resistance and electrical conductivity of the contacts, and the cost is also relatively high. That is to say, because the slip ring is in motion for a long time, the wear of the dynamic and static contacts is still relatively serious. Failures are also inevitable. Especially in the environment with relatively high humidity, the contact oxidation and corrosion are more serious, and...

AI Technical Summary

Problems solved by technology

[0002] At present, the three-dimensional scanning laser lamp mostly adopts the technical scheme of circular motion and electrical signal transmission using conductive slip rings. An obvious disadvantage of this technology is: because the conductive slip ring adopts the method of sliding contact between the static contact and the moving contact. For the transmission of electrical signals, the requirements for contact wear resistance, corrosion resistance, conductivity, etc. are relatively high, and the cost is also high. Even so, because the slip ring is in a state of motion for a long time, the wear and tear of the dynamic and static contacts is still relatively serious. Failures are also inevitable

Especially in an environment with relatively high humidity, the oxidation and corrosion of the contacts are more serious, and the probability of causing a conductive slip ring failure is also relatively high; The situation of the rail also happens from time to time, which affects the working stability of the conductive slip ring

It also increases the failure of the laser lamp and affects the service life. In view of this, we propose a three-dimensional scanning laser lamp without slip rings
