meanwhile, airflow for radiating the LED lamp beads 6 flows away from the fixed air outlet pipes 7 and is exhausted through the extension pipes 37, and no matter how the lighting device is installed, because the L-shaped guide pipe 34 can rotate relative to the fixed air outlet pipes 7, when one end of the L-shaped guide pipe 34 connected with the fixed air outlet pipes 7 is in a horizontal position, the other end of the L-shaped guide pipe 34 can always face downwards under the action of gravity, and when one end of the L-shaped guide pipe 34 connected with the fixed air outlet pipes 7 is in a vertical position, the universal ball 36 arranged at the other end of the L-shaped guide pipe can still rotate under the action of gravity, so that the extension pipes 37 face downwards, namely the air outlet ends are always facing downwards, and the probability of entering of external sundries is reduced;
the end part of the LED lamp bead 6 connected with the lamp shell 1 transmits the generated heat to the outside of the lamp shell 1 through the heat conducting metal tube 9, and the heat is dissipated through the heat dissipation metal plate 5, so that the LED lamp bead 6 is prevented from heating, meanwhile, because a gap exists between the heat dissipation metal plate 5 and the lamp shell 1, and simultaneously because the air pump 3 is arranged outside the lamp shell 1, the air pump 3 can drive the air flow of the surrounding space, thereby facilitating the heat dissipation of the heat dissipation metal plate 5;
when the temperature in the lamp shell 1 rises to a certain value, the first temperature sensing switch 18 enables the electric push rod corresponding to the telescopic stroke to extend and abut against the turnover flange 19, the turnover flange 19 pushes the annular supporting plate 20 downwards, the annular supporting plate 20 descends by means of the elastic corrugated telescopic sleeve 21, so that the rotary drum 14 can descend conveniently, the rotary drum 14 pushes the closed baffle 29 to slide a certain distance into the rotary ring 16 through the linkage rod 28 in the descending process, the ventilation position of the air hole 31 is reduced, the electric push rod with the larger telescopic stroke runs when the sensed temperature is higher, the descending distance of the rotary drum 14 is larger, the sliding distance of the closed baffle 29 to the rotary ring 16 is larger, even the ventilation position of the air hole 31 is smaller, the flow rate of the passing air is increased due to the ventilation caliber limitation, when the air flow with the increased flow rate passes through the outer wall of the LED lamp bead 6, the heat dissipation effect can be improved, the lighting device is prevented from generating heat, and the flow rate of the anti-heat-generating air flow can be adjusted according to the internal temperature;
the second temperature-sensing switch 15 is used for detecting the temperature in the heat-conducting metal cylinder 9, when the temperature of one or a plurality of LED lamp beads 6 is abnormally high and exceeds the corresponding temperature value, the second temperature-sensing switch 15 enables the electric telescopic rod 24 to contract, the sealing piece 25 slides to separate from the opening end of the sliding sleeve 26, the sliding sleeve 26 is communicated with the diversion channel 10, the air flow in the diversion channel 10 is partially diverted into the sliding sleeve 26, then the sliding sleeve 26 slides towards the inside of the heat-conducting metal cylinder 9 under the impact of the air flow, so as to drive the insulating separation piece 13 to slide and penetrate between the first conducting piece 12 and the second conducting piece 11, the corresponding LED lamp beads 6 are powered off, the whole lighting device is prevented from being influenced by continuous power-on operation overheating, meanwhile, the air flow acting in the sliding sleeve 26 is sprayed into the heat-conducting metal cylinder 9 through the spraying holes, upwards along the inside of the heat-conducting metal cylinder 9, and finally discharged from the heat-radiating holes 8, and the heat-conducting metal cylinder 9 is convenient for accelerating heat radiation.
