[0031] In the use process, first start heat dissipation fan 205. Heat dissipation fan 205 will blow the air outside installation box into the inner chamber of installation box 201, when air enters the inner chamber of installation box 201, will first pass through the filtration of filter assembly 202,

[0032] Then, the air in installation box 201 will be guided to the surface of LED lamp body 102 by air guide assembly 203, this process can clean the dust on the surface of LED lamp body 102, after cleaning, close closure assembly 206 in the bottom end of lamp shade 101, to prevent dust from entering the inside of lamp shade 101,

[0033] After that, open LED lamp body 102 to make it start working, the heat generated when LED lamp body 102 works will be conducted to the heat dissipation fin 204 in the inner chamber of installation box 201, since the air in installation box 201 is constantly circulated, these air will carry the heat on heat dissipation fin 204 to the inside of lamp shade 101 and discharge,

[0034] In addition, since the air circulation is started at the beginning, the temperature of LED lamp body 102 is always kept at a low level, therefore, the temperature of the air guided by air guide assembly 203 is also low, which does not affect the normal work of LED lamp body 102, solves the problem that the traditional LED eye protection lamp is designed in an open type, dust is easy to invade from the bottom end of the lamp shade or the heat dissipation hole, causes light attenuation, and the heat dissipation is poor, which is easy to overheat and shortens the service life of LED lamp.

[0035] Embodiment 2

[0036] With reference to Fig. 1 And Fig. 3 , the second embodiment of the utility model, different from the last embodiment, the lampshade 101 includes several groups of air outlet holes 101a, which are evenly distributed on the surface of the lampshade 101, the air inside the lampshade 101 can be discharged via the air outlet hole 101a, this design can effectively prevent the hot air from accumulating in the lampshade, thereby avoiding the adverse effects on the normal work of the LED lamp body 102, and because the air is continuously discharged outward, a certain airflow guide is formed, so that dust is difficult to enter the inner cavity of the lampshade 101 through the air outlet hole 101a.

[0037] Specifically, the mounting box 201 includes a clamping groove 201a, which is provided at the top end of the mounting box 201, the filter assembly 202 includes a cover plate 202a, which is provided at the top end of the mounting box 201, the top end of the filter assembly 202 is symmetrically provided with a filter screen 202b, the cover plate 202a includes an arc-shaped groove 202a-1, which is provided at both sides of the cover plate 202a, the cover plate 202a further includes an insertion block 202a-2, which is fixedly installed at the bottom end of the cover plate 202a, and the insertion block 202a-2 is connected with the clamping groove 201a, the cover plate 202a is precisely clamped into the clamping groove 201a in the top end of the mounting box 201 by means of the insertion block 202a-2 provided thereon, so as to complete the installation operation of the cover plate 202a, when the external air enters the inner cavity of the mounting box 201, it will be filtered by the filter screen 202b, thereby effectively preventing dust from accumulating in the inner cavity of the mounting box 201, in addition, the arc-shaped groove 202a-1 provided on the cover plate 202a provides convenience for taking the cover plate 202a.

[0038] Specifically, the air guide assembly 203 includes four groups of conical pipes 203a, which are annularly installed at the bottom end of the inner cavity of the mounting box 201, the mounting box 201 is provided with a wind guide pipe 203b at the bottom end, and the other end of the wind guide pipe 203b is provided with a spray head 203c, the air in the inner cavity of the mounting box 201 first flows into the wind guide pipe 203b through the conical pipe 203a, and then the air in the wind guide pipe 203b is guided and blown to the surface of the LED lamp body 102 by means of the spray head 203c.

[0039] Specifically, the closed assembly 206 includes a connecting ring 206a which is screwed at the bottom end of the lampshade 101, and the inner cavity of the connecting ring 206a is embedded with a soft light plate 206b. By rotating the connecting ring 206a, the soft light plate 206b can be accurately installed at the bottom end of the lampshade 101, realizing the closure of the bottom end of the lampshade 101 and effectively preventing air from entering the inner cavity of the lampshade 101 from the bottom end. At the same time, the light source emitted by the LED lamp body 102 will be radiated outward through the soft light plate 206b. The surface of the soft light plate 206b is in the form of a micro-prism array. This unique structure can make each beam of light emitted by the light source experience multiple reflections and refractions, thereby simulating a comfortable and natural diffuse reflection effect. In this way, it can effectively avoid the non-uniformity of the light source in space, making the light emission more uniform and soft, significantly improving the comfort of the user using the LED eye protection lamp, and ensuring that the bottom end of the closed lampshade 101 does not affect the normal lighting function of the lamp.

[0040] In use, the air in the lampshade 101 is discharged through the air outlet hole 101a, preventing the accumulation of heat-affected air from affecting the LED lamp body 102, and continuously discharging air to form an air current to prevent dust from invading from the air outlet hole 101a. The cover plate 202a is installed by being clamped into the top end clamping groove 201a of the installation box 201 by the insertion block 202a-2. The external air enters the installation box 201 and is filtered by the filter screen 202b to prevent dust accumulation. The air in the installation box 201 first enters the air guide pipe 203b through the conical pipe 203a, and then is blown towards the surface of the LED lamp body 102 by the spray head 203c.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application. They should all be covered in the scope of the claims of the present application.
