Abstract
Description
Technical Field
[0001] The utility model belongs to the field of LED lamps, and particularly relates to an LED floor eye protection lamp. Background Art
[0002] In the prior art, when the lamp head is set to a rotatable mode, a rotating shaft structure is generally provided. However, in the prior art, the rotating shaft structure of the lamp generally does not have a limiting structure or only has a clamping structure (such as a threaded structure for abutting) to fix the rotatable lamp head. However, the former is likely to cause the fixing angle of the lamp head to be unstable and the irradiation angle to shift easily due to accidental contact by the user. The latter may cause the loosening of the clamping structure with the use of the lamp, which will also cause the above problems. Therefore, a limiting mechanism needs to be provided for the rotating shaft structure of the lamp to fix the irradiation angle of the lamp head. At the same time, in order to enable the lamp head to be adjusted at multiple angles, multiple limiting structures are required to ensure the multi-angle adjustment of the lamp head. And because of the need for a limiting structure that can be adjusted at multiple angles, the structure of the entire lamp will be relatively complex. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the problem in the prior art that the LED lamp requires a limiting structure that can be adjusted at multiple angles but will result in a relatively complex limiting structure.
[0004] To achieve the above purpose, the utility model provides the following technical solution: an LED floor eye protection lamp, comprising a lamp head, a lamp pole and a base. An LED component is arranged in the lamp head. The lamp pole includes an upper lamp pole and a lower lamp pole. A bearing seat and a bearing are arranged between the upper lamp pole and the lower lamp pole. The upper lamp pole is relatively fixed to the bearing seat. A rotating shaft passes through the bearing seat and the bearing. The lower lamp pole is relatively fixed to the rotating shaft. The upper lamp pole can rotate relative to the rotating shaft. A limiting piece with a plurality of grooves is arranged between the rotating shaft and the bearing seat. The limiting piece is clamped on the rotating shaft and is relatively fixed to the rotating shaft. A plurality of elastic pieces pass through the bearing seat. The elastic pieces can pass through the bearing seat and sink into the grooves of the limiting piece so as to limit the rotation between the upper lamp pole and the rotating shaft. The lamp head is connected to the upper end of the lamp pole through a lamp head connecting piece. The lower end of the lamp pole is connected to the base through a base connecting piece.
[0005] Preferably, a UI control panel formed by a touch panel, a lamp control board bracket, and a UI film, as well as a control PCB board, are provided in the middle of the lamp post. A power supply component is provided in the lower half of the lamp post. An upper light source and a lower light source are provided inside the lamp head. A lower light source PCB component, an upper light source PCB component, and a driving PCB component are correspondingly provided inside the lamp head. The lower light source PCB component and the upper light source PCB component are electrically connected to the driving PCB component respectively. The driving PCB component is electrically connected to the control PCB board, and the control PCB board is electrically connected to the power supply component. The UI module panel is electrically connected to the control PCB board and controls the working state of the lamp head through the control PCB board. The switch, brightness, and mode adjustment of the lamp head are controlled through the touch panel and the UI film on the UI module panel.
[0006] Preferably, the elastic member is a ejector rod passing through a spring, and the ejector rod has an arc-shaped head structure that fits the groove.
[0007] Preferably, the upper lamp post is relatively fixed to the bearing seat through a threaded structure.
[0008] Preferably, a rotating base is provided inside the lower lamp post. The rotating shaft passes through the rotating base and connects the bearing seat and the rotating base, and the bearing seat can rotate relative to the rotating base.
[0009] Preferably, the lower lamp post is relatively fixed to the rotating base through a threaded structure.
[0010] The utility model has the following beneficial effects: The utility model provides an LED floor eye protection lamp. The upper and lower lamp posts limit the rotation of the lamp through a simple limit piece with a groove and a corresponding elastic member, and at the same time, the number of grooves can be set flexibly according to the required rotation angle. While ensuring that the rotation angle of the lamp head can be adjusted more precisely, there is no need to set a complex structure. BRIEF DESCRIPTION OF THE DRAWINGS
