DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Refer to the attached specification Figure 1-3 The utility model is an LED lamp structure, including a lamp housing 1, see Figure 2 A lampshade 2 is fixedly mounted on the bottom of the lamp housing 1, a circuit board 3 is fixedly mounted inside the lamp housing 1, an LED chip 4 is fixedly mounted on one side of the circuit board 3, and a heat dissipation fin 5 is fixedly mounted on the side of the circuit board 3 away from the LED chip 4, see Figure 3 A mounting member 6 is provided on one side of the heat dissipation fin 5, the mounting member 6 is fixedly installed inside the lamp housing 1, a fan 7 is fixedly installed inside the mounting member 6, an air intake duct 8 is opened inside the mounting member 6, a filter screen 9 is fixedly installed inside the air intake duct 8, a first air hole 10 is opened on the outer wall of the lamp housing 1, and the first air hole 10 is arranged on one side of the air intake duct 8;

[0022] A cleaning rod 11 is inserted into the interior of the mounting member 6, and the cleaning rod 11 is arranged on the outer wall of the filter screen 9. A push rod 12 is fixedly connected to the outer wall of the cleaning rod 11, and a push piece 13 is fixedly connected to the end of the push rod 12 away from the cleaning rod 11. The push piece 13 is slidably connected to the interior of the mounting member 6. A sealing member 14 is fixedly connected to one side of the push piece 13. The sealing member 14 is slidably connected to the interior of the mounting member 6. A pressure spring 15 is fixedly installed on one side of the sealing member 14. The pressure spring 15 is fixedly installed in the interior of the mounting member 6. For details, see Figure 2 An air outlet pipe 16 is opened inside the mounting member 6 , and the sealing member 14 is slidably connected inside the air outlet pipe 16 . A second air hole 17 is opened on one side of the lamp housing 1 , and the second air hole 17 is arranged on one side of the air outlet pipe 16 .

[0023] It should be noted that, when the temperature sensor detects that the internal temperature of the LED lamp has reached a certain temperature, the temperature sensor transmits an electrical signal to the controller, so that the controller controls the fan 7 to work, so that the fan 7 draws external air through the air inlet duct 8, and then the external air enters the interior of the air inlet duct 8 through the first air hole 10, so that the gas flows along the interior of the air inlet duct 8 and is filtered by the filter 9 to filter the internal dust and impurities, so as to prevent the dust from entering the interior of the LED lamp and affecting the heat dissipation of the LED lamp, and to prevent the dust from causing poor contact of the internal components of the LED lamp, and then the gas is blown by the fan 7 to flow along the interior of the lamp housing 1 and the lampshade 2, so that the gas takes away the heat transferred from the circuit board 3 and the LED chip 4 by the heat dissipation fins 5, and the circuit board 3 and the LED chip 4 are cooled. 4 is taken away together with the heat transferred to the lamp housing 1 and the lampshade 2, and then the gas gradually flows to one side of the push piece 13, so that the gas starts to blow the push piece 13 to slide along the inside of the mounting piece 6. The sliding of the push piece 13 will drive the sealing piece 14 to move together. The movement of the sealing piece 14 will squeeze the pressure spring 15 to contract and open the seal of the air outlet pipe 16 (the elastic force of the pressure spring 15 is relatively small, and it is only used to reset the sealing piece 14 and the push piece 13, so that the force required by the airflow to push the push piece 13 and the sealing piece 14 is relatively small). At this time, the gas is discharged from the LED lamp through the air outlet pipe 16 and the second air hole 17 with the heat, so as to achieve the effect of heat dissipation of the LED lamp, prevent the internal temperature of the LED lamp from being too high, and affect the luminous effect of the LED chip 4 and the overall service life of the LED lamp;

[0024] Furthermore, when the push member 13 slides along the inside of the mounting member 6, the push member 13 pushes the cleaning rod 11 to move through the push rod 12, so that the cleaning rod 11 slides along the outer wall of the filter 9 to clean the dust and impurities accumulated on the outer wall of the filter 9, so as to achieve the effect of automatically cleaning the dust and impurities on the filter 9, and prevent the dust from gradually clogging the filter 9, affecting the efficiency of the airflow, and further affecting the heat dissipation efficiency of the LED;

[0025] Furthermore, when the internal temperature of the LED returns to normal, the temperature sensor will control the fan 7 to stop working and stop the gas from flowing. At this time, the pressure spring 15 can push the seal 14 to reset, so that the seal 14 seals the air outlet pipe 16 to prevent external flying insects, dust and impurities from entering the interior of the LED lamp, and then the seal 14 drives the push piece 13 to move and reset, so that the push piece 13 pulls the cleaning rod 11 to reset through the push rod 12 and waits until the next work. At the same time, the first air hole 10 and the second air hole 17 are set as inclined air holes, so that after the external rainwater enters the interior of the first air hole 10 and the second air hole 17, it will slide out along the inclined holes inside the first air hole 10 and the second air hole 17 and will not enter the interior of the LED lamp, so as to prevent rainwater from entering the interior of the LED lamp and causing a short circuit in the LED lamp.
