The inside packing of heat dissipation case 5 has dichloromethane and distilled water, and regulation and control cover 6 and connecting rod 9 are non-conductive non-metallic material and make, avoid directly to insert flow regulation resistance 11 and heat dissipation resistance 13, and dichloromethane is relative distilled water, and its density is the bigger boiling point lower, is located regulation and control cover 6 lower parts promptly, and the outside heat dissipation of gasification that can be better and timely to automatic backward flow realizes the circulation heat dissipation after the heat dissipation liquefaction.
In the invention, when the lamp tube 3 is electrified and works normally, the temperature in the shell 1 is normal, and in this state, the current reducing plate 10 is contacted with the upper parts of the two current regulating resistors 11, so that the resistance of the current regulating resistors 11 actually connected to a circuit is extremely small, the brightness of the lamp tube 3 is normal, and the heat dissipation plate 8 is not contacted with the heat dissipation resistor 13, so that the fan 14 is not electrified and is in a static state;
along with the increase of the working time of the lamp tube 3, the temperature in the shell 1 rises gradually, the mounting plate 2 can fully absorb the heat emitted by the lamp tube 3 and conduct the heat to the heat dissipation box 5 in time, so that the dichloromethane in the heat dissipation box 5 absorbs a large amount of heat, the heat in the shell 1 is absorbed, the temperature is controlled, along with the continuous emission of the heat, the temperature in the shell 1 rises gradually, so that the dichloromethane with a lower low point can absorb enough heat to be gasified, and the dichloromethane is positioned at the bottom of the heat dissipation box 5 due to high density, can absorb more heat and isolate the distilled water at the upper part from being heated, so that the temperature difference between the upper part and the lower part of the heat dissipation box 5 is larger, the dichloromethane heated and gasified at the bottom flows upwards in the form of bubbles and then diffuses in the distilled water at the upper part, and because the boiling point of the distilled water is high, the specific heat capacity is large, the heat, the dichloromethane at the bottom absorbs the heat inside the shell 1 more quickly and transfers the heat to the distilled water, so that the heat inside the shell 1 is diffused in time, and the temperature is effectively controlled;

the more dichloromethane gas is gathered at the top, the more the current reducing plate 10 is lowered, the larger the access resistance of the current regulating resistor 11 is, the smaller the access current of the lamp tube 3 is, the lower the calorific value is, so that the internal temperature of the shell 1 is regulated, meanwhile, the downward movement process of the current reducing plate 10 synchronously drives the heat dissipation plate 8 to move downward, so that the heat dissipation plate 8 communicates the two heat dissipation resistors 13, the fan 14 is powered on to work, and the air force of the fan 14 blows, so that the internal and external air flows of the shell 1 flow and exchange heat, so that the internal temperature of the shell 1 is rapidly reduced, the more the heat dissipation plate 8 is moved downward, the lower the access resistance of the heat dissipation resistor 13 is, the faster the rotating speed of the fan 14;
after the current reducing plate 10 is reduced to a certain degree, the current reducing plate will be separated from the two current regulating resistors 11 and abut against the auxiliary plate 12, so that the circuit connecting the lamp tube 3 is interrupted, the lamp tube 3 does not generate heat actively any more, the lamp tube 3 is prevented from being damaged due to continuous work at a high temperature, the fan 14 will continuously work and be in a strong state, so that the internal temperature of the shell 1 is reduced rapidly, after the internal temperature of the shell 1 is recovered to be stable, the current reducing plate 10 will move upwards under the elastic force of the return spring 7 to be reset, so that the lamp tube 3 is recovered to work, the internal temperature of the shell 1 is kept in a higher state continuously, generally, a circuit fault occurs, and the circuit current is increased to form, or a user forgets to close the lamp tube 3, so that the lamp tube is continuously lighted, the self-closing protection of the lamp tube 3 cannot affect the use of the user, and the brightness of the lamp tube 3 before, play good suggestion effect, even if the user intentionally also can help the user to know the operating condition of fluorescent tube 3, in time deal with.
