Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an LED lamp with an adjustable lamp arm structure. Background Art

[0002] LED lighting, or light-emitting diode lighting, is a semiconductor solid-state light-emitting device. It uses a solid semiconductor chip as the luminescent material. Carrier recombination within the semiconductor releases excess energy, causing photon emission, directly emitting red, yellow, blue, and green light. Furthermore, by utilizing the principle of the three primary colors and adding phosphors, it can emit light in any color. Lighting fixtures using LEDs as a light source are called LED lamps. Among LED lighting fixtures, reflective LED lamps are perfectly suited for any application.

[0003] In the existing technology, as people's demand for lighting continues to increase, traditional fixed LED lamps can no longer meet the diverse usage needs. In order to adapt to different application scenarios, such as home, office, outdoor work, etc., LED lamps with adjustable lamp arm structures are gradually favored by users. This type of lamp uses an adjustable lamp arm design to enable users to flexibly change the height and angle of the light to meet the lighting needs in different environments and occasions. However, there are some problems with the adjustable lamp arm structure in actual use. First, the adjustment and fixing mechanisms of many adjustable lamp arms are relatively complicated. When users adjust the height of the lamp arm, they often need to repeatedly operate the limit device, which is time-consuming and labor-intensive, and reduces the user experience. Secondly, when fixing the lamp arm of some lamps, the locking device is not stable enough and is prone to accidental loosening, causing the lamp arm to slide during use, thereby affecting the stability of the light and the lighting effect.

Then, the spring will use its own retraction to push the extrusion rod back to its original position. At the same time, the center plate will change the angle of the oblique rod on the center plate due to the lack of support from the push rod. The four locking rods will gradually retreat under the action of the internal springs and disengage from the connecting rod. As a result, they will no longer rub against the inner wall of the connecting rod, thus releasing the fixed restriction on the lamp arm.
