In this embodiment, the heat dissipation mechanism includes vent 10 and the spacing groove 8 of seting up in the lateral wall of heat-insulating box 1 on the lateral wall of heat-insulating box 1, and spacing groove 8 is located vent 10 top and is linked together with vent 10, and slidable mounting has magnetic seal board 9 in the spacing groove 8, and the specification of magnetic seal board 9 is slightly greater than the specification of vent 10 to improve the leakproofness of magnetic seal board 9 to vent 10, the one side that heat conduction piece 3 is close to vent 10 inlays and is equipped with magnetic stripe 5.
Each expansion ball 7 is filled with thermal expansion medium, each counterweight ball 4 is made of elastic rubber, and the gravity center of the heat conduction block 3 is positioned on the horizontal central axis of the heat conduction block in a natural state.
When the lamp is used in the embodiment, in an initial state, the conducting plate on the shell of the lamp 2 is attached to the electric connecting piece 11, and at the moment, the lamp tube, the conducting plate and the electric connecting piece 11 are connected into the working circuit, so that the lamp tube emits light;
the gravity center of the heat-conducting block 3 is located on the horizontal central axis of the heat-conducting block, as shown in fig. 3, the expansion ball 7 is distributed on the lower half part of the rotary groove 31, the counterweight ball 4 is distributed on the upper half part of the rotary groove 31, at the moment, the coil spring 6 is in a natural state, the temperature in the heat-insulating box 1 can gradually rise along with the increase of illumination time, the heat-conducting block 3 has better heat conductivity and can absorb more heat, when the temperature of the heat conduction block 3 is higher than 30 ℃, the expansion speed of the thermal expansion medium is greatly increased, thereby, the volume of the expansion ball 7 is increased significantly, and at this time, the expansion ball 7 presses the weight ball 4, as shown in fig. 4, the center of gravity of the heat conduction block 3 is shifted upward, thereby leading the heat conduction block 3 to spontaneously rotate 180 degrees, leading the conducting plate to be staggered with the power connection plate 11, cutting off the power of the lamp tube, simultaneously, since one end of the coil spring 6 is connected to the inner wall of the circular groove 32 and the other end is connected to the fixing rod 61, the heat-conducting block 3 rotates to place the coil spring 6 in a stretched state;

Referring to fig. 5, the present embodiment is different from embodiment 1 in that: a plurality of elastic parts 12 with the same specification are symmetrically arranged between the electric connecting piece 11 and the heat conducting block 3, the edge of the electric connecting piece 11 is chamfered, and a limiting ring 13 is fixedly arranged on the heat conducting block 3 to ensure that the electric connecting piece 11 always moves along a straight line.
When the electric connecting piece 11 is attached to the conductive piece in the use of the embodiment, under the action of the elastic piece 12, the electric connecting piece 11 generates certain pressure on the conductive piece, so that the electric connecting piece and the conductive piece are attached more tightly, and the problem that the electric connecting piece 11 is worn and cannot be attached to the conductive piece after long-term use of equipment is solved;
because the edge of the electric connecting piece 11 is turned with a chamfer, as shown in fig. 5, when the electric connecting piece 11 is close to the conductive piece, the stress direction of the electric connecting piece 11 can be changed by the arc-shaped chamfer, so that the electric connecting piece 11 is firstly inclined by an angle, and the electric connecting piece 11 is balanced after the conductive piece slides onto the electric connecting piece 11, therefore, the problem that the electric connecting piece 11 and the conductive piece cannot be attached due to the fact that the side wall of the conductive piece is abutted to each other cannot occur.
