LED lamp provided with rotating mechanism

Abstract

The invention discloses an LED lamp provided with a rotating mechanism. The LED lamp comprises a lamp bracket, and a parallel rotating piece slidingly arranged on the lamp bracket so as to rotate in parallel on the surface where the lamp bracket is located. The LED lamp provided with the rotating mechanism further comprises a setting part, a friction guide part, a radial rotating piece and a rotating supporting part; the setting part is arranged on the lamp bracket and follows the parallel rotating piece to rotate, and the setting part and the parallel rotating piece rotate in parallel together; the friction guide part is arranged on the setting part; the friction guide part and the parallel rotating piece are arranged in a spaced manner; the radial rotating piece is in pressing connection fit with the friction guide part, so as to rotate around the friction guide part and to rotate back and forth relative to the two sides of the lamp bracket; and the rotating supporting part is movably arranged on the parallel rotating piece, so as to follow the radial rotating piece to rotate back and forth together and to allow the rotation radius of the radial rotating piece relative to the parallel rotating piece to be kept unchanged in a rotating process. The parallel rotating piece and the radial rotating piece of the LED lamp provided with the rotating mechanism are arranged in a spaced manner, so that the mounting is facilitated, and the change range of the illumination direction is expanded.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED lamp with a rotating mechanism. Background technique [0002] As the luminous efficiency of LEDs (Light Emitting Diodes, light-emitting diodes) continues to increase, and LEDs have the advantages of good light-gathering performance and high brightness, they are popular among consumers. In practical lighting requirements, LED lamps not only need to provide higher lighting brightness, but also can still adjust the lighting area after the installation is completed. In the prior art, the adjustment of the irradiated area is generally realized by adjusting the lamp head, so a corresponding rotating mechanism is required to realize the adjustment of the lamp head. In particular, some LED lamps require the lamp head to rotate in a plane relative to the surface parallel to the lamp holder, and also require the direction of the light emitted by the lamp holder to change, that is, to rotate back and forth...

AI Technical Summary

Problems solved by technology

However, there are many difficulties in realizing the rotation of the rotation mechanism of this kind of LED lamp.

In practice, due to the complex mechanism and large size, it needs to occupy a large space on the lamp stand and has high requirements for the installation environment and makes installation more difficult

For another example, in order to change the irradiation direction of the lamp holder, it is necessary to set the lamp holder on the edge of the lamp holder so that it can rotate relative to the two sides of the lamp holder. In the through hole space in the middle of the ring lamp holder, if the rotation mechanism is set closer to the through hole in the ring lamp holder, the rotation range of the lamp head will be limited; The closer the through holes and the larger the rotation range, the larger the gap between the lamp head and the edge of the ring lamp holder will affect the appearance
