by arranging the anti-dropping ring 14, when each electromagnet is in a power-off state and the mounting seat 17 drives the LED anti-explosion lamp beads to actively slide out of the sliding cylinder 5 due to the tensile force of the active spring 9, the fixed disc 10 is prevented from dropping from the second guide post 13, so that the butt joint operation of the fixed disc 10 and the second guide post 13 is difficult to complete; similarly, through set up elasticity hemisphere 19 in both sides, when avoiding slide cartridge 5 to the outer roll-off of lamp stand 2, because inertia influence leads to mount pad 17 and the explosion-proof lamp pearl of inside LED to rush out slide cartridge 5, further improves the practicality and the security of this application explosion-proof lighting fixture of LED.
The working principle of the invention is as follows: when the LED explosion-proof lamp bead breaks down, the second electromagnet is powered on, the attraction force generated by the magnetic field generated by the second electromagnet on the metal ring 6 overcomes the tensioning effect of the driving spring 9 on the sliding cylinder 5, so that the LED explosion-proof lamp bead is extinguished visually, but the sliding cylinder 5 and the LED explosion-proof lamp bead are not popped out of the lamp holder 2, the power-on loop of the second electromagnet is disconnected by pressing the switch, the magnetic field generated by the second electromagnet disappears, the sliding cylinder 5 and the LED explosion-proof lamp bead actively slide out of the lamp holder 2 under the elastic force action of the driving spring 9, and time and labor are saved compared with the existing mode of screwing out the LED explosion-proof lamp bead in a spiral mode; when the power supply line breaks down, LED explosion-proof lamp pearl is extinguish but not damaged this moment, first electro-magnet 4 all keeps the outage state with the second electro-magnet, first electro-magnet 4 disappears with the produced magnetic field of second electro-magnet, metal loop 6 does not receive the magnetic force influence, under the spring action of initiative spring 9, with slide cartridge 5 and inside LED explosion-proof lamp pearl follow lamp stand 2 interior initiative roll-off, thereby realize conveniently popping out LED explosion-proof lamp pearl and can also initiatively judge the trouble that appears when realizing fast overhaul and belong to the bulb damage or the circuit trouble, independently detect the fault type.
Through the arrangement of the fixed disk 10 and the threaded sleeve 11, when the focal distance of the LED explosion-proof lamp bead needs to be adjusted, after the lamp shade 1 and the lamp holder 2 are disassembled, the sliding cylinder 5 is dragged in the direction away from the lamp holder 2 through the metal ring 6, after one end of the threaded sleeve 11 penetrates through the annular seat plate 7, the metal ring 6 is rotated, under the limiting action of the second guide post 13 and the tensioning action of the driving spring 9, the sliding cylinder 5 drives the fixed disk 10 to rotate, so that the relative position of the fixed disk 10 and the threaded sleeve 11 is changed, namely the distance between the metal ring 6 and the first electromagnet 4 in the non-electrified state of each electromagnet is changed, namely the initial position of the LED explosion-proof lamp bead in the same state is changed, the focal distance of the LED explosion-proof lamp bead is changed, the sliding cylinder 5 can be restrained by arranging the first guide post 8 and the first chute which are matched with each other, so that the magnetic force and the spring at two ends of the sliding cylinder 5 are changed, do rectilinear motion, avoid taking place the upset phenomenon to ensure that unexpected rotation phenomenon can not appear in fixed disk 10 and threaded sleeve 11, thereby realize guaranteeing that the focus remains stable when need not to change explosion-proof lamp pearl focus of LED.
By arranging the anti-dropping ring 14, when each electromagnet is in a power-off state and the mounting seat 17 drives the LED anti-explosion lamp beads to actively slide out of the sliding barrel 5 under the action of the tension of the active spring 9, the fixed disc 10 is prevented from dropping from the second guide column 13, so that the butt joint operation of the fixed disc 10 and the second guide column 13 is difficult to complete; similarly, through set up elasticity hemisphere 19 in both sides, when avoiding slide cartridge 5 to the outer roll-off of lamp stand 2, because inertia influence leads to mount pad 17 and inside LED explosion-proof lamp pearl to dash out slide cartridge 5, further improves the practicality and the security of this application LED explosion-proof lighting fixture.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
