DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0021] See also Figure 1 - Figure 5 The protective device for an LED lamp of the present embodiment comprises a housing 1, a lamp sheet 2 and a protective cover 14. A notch is provided at the top of the housing 1. A support plate 3 is installed on the inner two walls of the notch at the top of the housing 1. The lamp sheet 2 is installed on the top of the support plate 3. The outer peripheries of the two sides of the support plate 3 are symmetrical arc sections. The arc sections on both sides of the support plate 3 and the inner wall of the notch of the housing 1 form an active cavity 4. A control board 13 is embedded and installed at the bottom of the support plate 3. Two sets of guard plates 15 are symmetrically installed on the top of the support plate 3.

[0022] Further, a driving structure for driving the protective cover 14 to rotate is provided on the housing 1, and the driving structure cooperates with the protective cover 14 to protect the light sheet 2. The driving structure is composed of an internal gear 5, a base 6, a first fixing frame 7, a micro motor 8, a bevel gear set 9, a second fixing frame 10, a connecting shaft 11 and an external gear 12, wherein two groups of internal gears 5 are symmetrically and movably mounted on the two side walls of the inner cavity of the housing 1, and the protective cover 14 is mounted on the opposite inner side tooth frames of the two groups of internal gears 5, and the internal gear 5 and the protective cover 14 are movably located in the inner cavity of the movable cavity 4;

[0023] Further, two groups of bases 6 are symmetrically installed on the bottom wall of the inner cavity of the shell 1, the first fixing frame 7 and the second fixing frame 10 are distributed and installed on the top of the base 6, the micro motor 8 is installed on one end of the first fixing frame 7, and the connecting shaft 11 is installed in the second fixing frame 10 through a bearing. A group of bevel gears of the bevel gear set 9 is installed on the other end of the first fixing frame 7 through a bearing, and the output end of the micro motor 8 is connected to its bevel gear end shaft, and another group of bevel gears of the bevel gear set 9 is connected to one end of the connecting shaft 11, and two groups of external gears 12 are symmetrically and movably installed on both side walls of the inner cavity of the shell 1, and the external gears 12 are meshed with the internal gears 5 through teeth, and the other end of the connecting shaft 11 is connected to the external gears 12;

[0024] Furthermore, the driving structure is used to drive the protective cover 14 to rotate. When the light sheet 2 needs to be protected, the micro motor 8 is started to drive the outer gear 12 to rotate through the cooperation of the bevel gear set 9 and the connecting shaft 11, and then the outer gear 12 drives the internal gear 5 meshing therewith to rotate. Since the internal gear 5 and the protective cover 14 are movably located in the inner cavity of the movable cavity 4, the rotation of the internal gear 5 can drive the protective cover 14 to rotate. When the protective cover 14 rotates to the bottom section thereof and connects with the top of the housing 1, the protective cover 14 is located above the light sheet 2. The protective cover 14, the guard plate 15, the support plate 3 and the housing 1 cooperate to form a structure surrounding the light sheet 2. The protective cover 14 and the guard plate 15 are made of highly light-transmitting materials, which can protect the light sheet 2 without affecting its lighting effect.

[0025] Furthermore, when the lamp piece 2 needs to be replaced after using it for a period of time, the user starts the micro motor 8 again to drive the internal gear 5 to rotate, and then drives the protective cover 14 to rotate through the internal gear 5. When the protective cover 14 rotates to be completely located in the inner cavity of the shell 1, the support plate 3 and the lamp piece 2 are completely exposed to the outside, which is convenient for the staff to replace the lamp piece 2. After replacing and installing the new lamp piece 2, the micro motor 8 is started again to drive the protective cover 14 to rotate to the appropriate position for protection. Therefore, by setting a driving structure to drive the protective cover 14 to rotate, it is convenient to protect the LED lamp body, facilitate the replacement, installation and use of the LED lamp, and improve the practicality of the overall protective device.

[0026] Working principle: When the light sheet 2 needs to be protected, the micro motor 8 is started to drive the outer gear 12 to rotate through the cooperation of the bevel gear set 9 and the connecting shaft 11, and then the inner gear 5 and the protective cover 14 rotate. When the protective cover 14 rotates to its bottom section and connects with the top of the shell 1, the protective cover 14 is located above the light sheet 2. The protective cover 14, the guard plate 15, the support plate 3 and the shell 1 cooperate to form a structure surrounding the light sheet 2. The protective cover 14 and the guard plate 15 are made of high light-transmitting materials, which can protect the light sheet 2 without affecting its lighting effect. After using it for a period of time, When the lamp piece 2 needs to be replaced, the user starts the micro motor 8 again to drive the internal gear 5 and the protective cover 14 to rotate. When the protective cover 14 rotates to be completely located in the inner cavity of the shell 1, the support plate 3 and the lamp piece 2 are completely exposed to the outside, which is convenient for the staff to replace the lamp piece 2. After replacing and installing the new lamp piece 2, the micro motor 8 is started again to drive the protective cover 14 to rotate to an appropriate position for protection. Therefore, by setting a driving structure to drive the protective cover 14 to rotate, it is convenient to protect the LED lamp body, facilitate the replacement, installation and use of the LED lamp, and improve the practicality of the overall protective device.
