Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to an LED eye protection lamp. Background Art

[0002] LED eye protection lamp is a lighting device that uses LED (light emitting diode) as a light source. It has low energy consumption and high light efficiency. It also has eye protection function. Compared with traditional incandescent lamps or fluorescent lamps, LED eye protection lamps are efficient, environmentally friendly, healthy and long-life lighting equipment that can meet people's needs for a comfortable and healthy lighting environment. Combined with the existing literature, a household low-power LED eye protection lamp (CN209511680U) document shows that through the mutual cooperation between the longitudinal groove, longitudinal rod, control rod, tension spring and clamping rod, pulling the control rod downward can make the longitudinal rod slide downward inside the longitudinal groove, and then the clamping rod is clamped at the bottom of the desktop. The tension spring provides an upward pulling force on the longitudinal rod, so that the LED eye protection lamp can be tightly connected to the desktop to avoid damage caused by the LED eye protection lamp tipping over, thereby improving the practicality of the LED eye protection lamp. It can be seen that at least the following defects are exposed during use:

[0003] 1. Currently, most of the LED eye protection lamps on the market have a common lampshade wrapped around the lamp head. Although this design can better protect the lamp head while condensing the light source, in real life, the condensed light source is relatively fixed and the light-emitting end close to the user's eyes in a dark environment has no soft transition, which is easy to flash the user's eyes during use. Therefore, there is a need for an LED eye protection lamp that can flexibly adjust the condensed light source while taking into account the function of soft transition light source.

[0004] 2. In combination with the above-mentioned literature, it can be seen that although the universal rod design in the document can flexibly adjust the rotation angle of the LED lamp, in daily life, due to the low supporting strength of the universal rod and the influence of its own weight for a long time, it is very easy to age during use, thereby affecting the angle adjustment function of the LED eye protection lamp. Therefore, there is a need for an LED eye protection lamp that can maintain a good steering function while taking into account a certain stability. Utility Model Content

[0005] The purpose of the utility model is to provide an LED eye protection lamp to solve the problems of the existing LED eye protection lamp during use proposed in the above background technology.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1 , 2As shown, an LED eye protection lamp includes a base 1, and a switch 15 is installed above the base 1 for intelligent control of the entire LED eye protection lamp. The maximum angle of rotation of the first connecting rod 2 and the second connecting rod 3 can reach 180 degrees. The span of the holes on the positioning ring 5 is larger than the span of rotation of the first connecting rod 2 and the second connecting rod 3. The length of the first plug 7 is just enough to pass through the first positioning hole 8 and be fixed on the second connecting rod 3, so that there is part remaining to ensure that the positioning ring 5 does not fall off. The first fixing screw 6 cooperates with the first connecting rod 2 to limit and fix the positioning ring 5, and the positioning ring 5 can just rotate around the first fixing screw 6.

[0025] like Figure 3 , 4 As shown, the connecting block 14 and the second connecting rod 3 are rotatably connected to adjust the lighting angle of the lighting head 4 in the vertical direction. The translucent frosted lamp cover 9 is responsible for condensing the light source in the lighting head 4 and weakening the edge light source. The two second fixing screws 10 and the second plug 12 cooperate with the multiple second positioning holes 11 and the third positioning holes 13 opened on the translucent frosted lamp cover 9 to adjust the vertical position of the translucent frosted lamp cover 9.

[0026] Working principle: When in use, first turn on the switch 15 located above the base 1. The user can adjust the height of the light source by adjusting the rotation angle of the first connecting rod 2 and the second connecting rod 3, then rotate the positioning ring 5 to the desired position, and insert the first plug 7 through the first positioning hole 8 at the corresponding position on the positioning ring 5 into the groove opened on the second connecting rod 3 to complete the positioning. While adjusting the height of the light source, the stability between the first connecting rod 2 and the second connecting rod 3 is also guaranteed. The user can also adjust the rotation angle of the second connecting rod 3 and the connecting block 14 to achieve the purpose of adjusting the light source angle. The translucent frosted lampshade 9 can aggregate the light source of the lighting head 4 to a certain extent, and weaken the external light source of the lighting head 4 to a certain extent, thereby reducing the stimulation to the user's eyes. During use, first adjust the translucent frosted lampshade 9 to a suitable height, then pass the second fixing screws 10 through the second positioning holes 11 at both ends of the translucent frosted lampshade 9 and install it on the connecting block 14, and the second plug 12 passes through the third positioning hole 13 at the corresponding height on the same straight line and is fixed to one end of the lighting head 4 to complete the adjustment.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
