The principle of operation of the present invention will now be described as follows: after the lamp housing 1 is arranged in an automobile, the LED control circuit board 3 and the singlechip 14 are communicated with a power supply system of the automobile, the first alarm 15 and the second alarm 19 are communicated with an automobile machine system of the automobile, the LED lamp group 2 can be controlled to work through the LED control circuit board 3 by the automobile machine system of the automobile, and the LED lamp group can be used as an LED automobile lamp in cooperation with the lamp housing 1 and the transparent lampshade 4;

after each time the automobile is started, the singlechip 14 is synchronously started, the singlechip 14 immediately controls the micro air pump 162 to be electrified and work, and immediately controls the normally open electromagnetic valve 174 in the circulation hole 173 and the spotlight 10 to work for 10 seconds at fixed time, at this time, the suction end of the micro air pump 162 can suck air in the lamp housing 1 and convey the air to the annular air cavity 163 through the air outlet end, then the air enters the air inlet grooves 114 through the air inlet holes 115, finally, the air enters the round grooves 7 through the air inlet grooves 114, and as the air enters the round grooves 7, the first piston 111 can be pushed to move outwards along the round grooves 7 under the action of air pressure, the square column 8 can be driven to move outwards synchronously through the connecting rod 112, the spotlight 10 can be pushed out outwards synchronously, and after the micro air pump 162 is started and works for 2 seconds, the first piston 111 can be pressed against the limit frame 116, at this time, the square column 8 stops moving, and the light of the spotlight 10 can pass through the transparent lamp housing 4, part of the light can be reflected and refracted by the transparent lamp housing 4, and the other part of the light can penetrate through the transparent lamp housing 4 and irradiate the transparent filter 132 at the position of the fixed groove 12;

when the transparent lampshade 4 is not oxidized to generate a yellowing phenomenon, as the transparency of the transparent lampshade 4 is good, the light irradiated to the yellow light filter 132 is not greatly different from the original light emitted by the spotlight 10, the yellow light filter 132 only carries out unidirectional recognition transmission on yellow light, when the transmitted light irradiates on the photoelectric component 131, the light energy can excite electrons in the semiconductor of the photoelectric component 131 to jump from valence band to conduction band to generate electron-hole pairs, the transition process can generate a current in the semiconductor, and the current is synchronously increased along with the increase of the light intensity, when the transparent lampshade 4 is not oxidized to generate the yellowing phenomenon, the intensity of the light transmitted to the photoelectric component 131 through the yellow light filter 132 is selected to be lower, so that the current generated by the photoelectric component 131 is smaller, and after the current generated by the photoelectric component 131 is amplified by the amplifying circuit of the singlechip 14, the current which is sufficient to be fed into the first electromagnetic switch 133 still cannot enable the moving contact of the first electromagnetic switch 133 to be magnetically closed, so that the first alarm 15 does not work;

when the transparent lampshade 4 generates yellowing phenomenon due to aging and oxidization, the light irradiated to the yellow filter 132 from the spotlight 10 through the yellowing position of the transparent lampshade 4 is yellow, the light intensity projected to the photoelectric component 131 through the yellow filter 132 is increased, so that the current generated by the photoelectric component 131 is larger, the current generated by the photoelectric component 131 is amplified by the amplifying circuit of the singlechip 14, enough current can be introduced into the first electromagnetic switch 133, at the moment, the movable contact of the first electromagnetic switch 133 is magnetically closed, the singlechip 14 immediately controls the first alarm 15 to work after receiving the closing electric signal of the first electromagnetic switch 133, and the first alarm 15 can display the yellowing prompting signal of the transparent lampshade 4 on the instrument panel of an automobile through the automobile machine system;

while the yellowing detection of the transparent lampshade 4 is performed, the micro air pump 162 continuously sucks out the air in the lamp housing 1 and discharges the air into the annular air cavity 163 within 10 seconds of the regular operation of the normally open electromagnetic valve 174 in the circulation hole 173, so that the lamp housing 1 is in a negative pressure state, at this time, under the action of the air pressure difference between the inside and the outside of the lamp housing 1, the outside air pushes the second piston 182 to move towards the mounting block 184 through the round hole 186, under the condition that the tightness between the lamp housing 1 and the transparent lampshade 4 is good, the outside air cannot enter due to the good tightness, at this time, the second piston 182 can touch and press the moving contact of the pressure switch 185 within 6 seconds to 7 seconds, if the tightness in the inside of the lamp housing 1 fails, the outside air can be supplemented into the inside of the lamp housing 1 through the sealing failure part, and because the inside of the supplementation of the outside air is possessed by the inside of the lamp housing 1, therefore, the second piston 182 cannot normally touch and close the moving contact of the pressure switch 185 within 6 seconds to 7 seconds, and after the automobile is started, under the control of the singlechip 14, the connection loop between the second alarm 19 and the pressure switch 185 can be delayed to be electrified for 8 seconds under the action of the electrifying delay relay 187, namely, under the condition that the sealing property of the lamp housing 1 is good, the moving contact of the pressure switch 185 can be closed by the second piston 182 within 6 seconds to 7 seconds, so that at the 8 th second, the moving contact of the pressure switch 185 is closed, at the moment, the connection loop between the pressure switch 185 and the second alarm 19 is disconnected, so that the second alarm 19 cannot be electrified to operate, and under the condition that the sealing of the lamp housing 1 is invalid, at the 8 th second, because the moving contact of the pressure switch 185 is not normally closed by the back pressure, at this time, the connection loop between the pressure switch 185 and the second alarm 19 is connected, so that the second alarm 19 can be electrified to work, and the second alarm 19 can display a prompt signal of the sealing failure of the lamp housing 1 on an instrument panel of the automobile through the automobile machine system so as to remind personnel to repair the sealing failure of the lamp housing 1 in time;

after the normally open electromagnetic valve 174 and the spotlight 10 in the circulation hole 173 work for 10 seconds at regular time, under the control of the singlechip 14, the spotlight 10 and the normally open electromagnetic valve 174 are powered off to stop working, at this time, the normally open electromagnetic valve 174 is in an open state, so high-pressure air in the annular air cavity 163 can quickly flow back into the lamp housing 1 through the circulation hole 173, the inside of the lamp housing 1 and the inside of the annular air cavity 163 are restored to normal pressure, at this time, under the action of the first spring 113, the first piston 111 can be pulled to cooperate with the connecting rod 112 to enable the square column 8 to move back and reset, and under the continuous working of the micro air pump 162, air in the lamp housing 1 is continuously sucked in and circularly flows in the lamp housing 1 and the annular air cavity 163 through the annular air cavity 163, the circulation hole 173 and the communication hole 175, the circularly flowing air flow can take away heat in the lamp housing 1, and hot air flow can heat exchange heat with external air and a frame of an automobile through the aluminum alloy heat exchange plate 171 to reduce the temperature in the lamp housing 1, and excessive temperature rise is prevented;

the air flowing in the annular air cavity 163 contacts the moisture-absorbing round ball 205, when the tightness of the lamp housing 1 is good, the air in the lamp housing 1 is very dry, the moisture-absorbing round ball 205 can not absorb moisture at the moment, and if the sealing of the lamp housing 1 fails, the air outside can enter the inside of the lamp housing 1 through the sealing failure part of the lamp housing 1, and under the internal circulation effect of the air flow, the moisture can contact the moisture-absorbing round ball 205, the moisture-absorbing round ball 205 can absorb the moisture, on one hand, the humidity of the air in the lamp housing 1 can be reduced as much as possible when the sealing of the lamp housing 1 fails, on the other hand, the weight of the moisture-absorbing round ball 205 can be increased along with the continuous moisture absorption and weight increase of the moisture-absorbing round ball 205, so that the insulating slide bar 203 can be pulled to move downwards until the conductive sleeve 206 contacts the conductive ring 207, and in the initial state of the starting of the automobile, because the automobile is still in the static state, therefore, the automobile will not move down due to the vibration of the automobile, after the automobile is started, the singlechip 14 will control the connection loop between the second electromagnetic switch 208 and the second alarm 19 to supply power for 20 seconds at regular time, if the hygroscopic ball 205 sucks enough moisture, the sealing failure of the lamp housing 1 is indicated, in 20 seconds of the connection loop between the second electromagnetic switch 208 and the second alarm 19 being supplied with power at regular time, the second electromagnetic switch 208 will be electrified due to the contact of the conductive sleeve 206 and the conductive ring 207, at this time, the moving contact of the second electromagnetic switch 208 is magnetically closed, so that the second electromagnetic switch 208 can switch on the connection loop between the second alarm 19 and the singlechip 14, at this time, the second alarm 19 can display the indication signal of the sealing failure of the lamp housing 1 on the instrument panel of the automobile through the automobile computer system, to remind personnel to repair the sealing failure of the lamp housing 1 in time;

the singlechip 14 controls the first alarm 15 and the second alarm 19 to continuously power on until the automobile stops power off, so that the first alarm 15 is prevented from stopping prompting operation due to rebound reset of the moving contact of the first electromagnetic switch 133 when the transparent lampshade 4 is in yellowing phenomenon, and the second alarm 19 is prevented from stopping prompting operation due to rebound reset of the moving contact of the pressure switch 185 and rebound reset of the moving contact of the second electromagnetic switch 208 when the sealing of the lamp shell 1 fails, and the alarm prompting operation of the first alarm 15 and the second alarm 19 is ensured.
