[0045] When used, the specific installation method is as follows:

[0046] First, the light source rear cover 102 is fixedly connected with the face frame 101 through the first threaded fastener, secondly, the power supply bracket 212 is used to fixedly arrange the power supply lower shell 213 and the power supply upper shell 201 on the surface of the light source rear cover 102 through the second threaded fastener, meanwhile, a plurality of threaded fixing points are installed between the power supply upper shell 201 and the power supply lower shell 213, and the power supply upper shell 201 and the power supply lower shell 213 are tightly connected, meanwhile, a plurality of supporting rods 203 are installed in the space between the power supply upper shell 201 and the power supply lower shell 213, the supporting rods 203 are designed as hollow, and the power storage device 205 is fixed on the middle position of the power supply lower shell 213 through the mounting frame, then the power supply wire 211 on the power storage device 205 is inserted into the inside of the supporting rod 203, and extends to the inside of the light source rear cover 102 along the inside of the supporting rod 203 and is connected with the power supply plate 103, so that the power supply function of the plurality of lamp beads 104 is completed, finally, the face frame 101, the light source rear cover 102 and the power supply unit 2 are synchronously embedded into the inside of the ship or the indoor ceiling, and the bottom of the face frame 101 always keeps horizontal state with the ceiling, and a plurality of screws and nuts are installed around the bottom of the face frame 101 to realize the preliminary fixing work of the face frame 101, the light source rear cover 102 and the power supply unit 2.

[0047] In addition, the fixed support 301 is installed on the side of the face frame 101 facing the light source rear cover 102 through the fixed sheet 303, and the screw rod is inserted into the inside of the fixed support 301, then the protective nut is arranged on the end of the screw rod close to the top of the fixed support 301, so as to avoid the screw rod from being separated from the fixed support 301, secondly, the pressing block 302 is arranged on the outer side surface of the screw rod, and the pressing block 302 is threadedly connected with the surface of the screw rod, so that the screw rod can be rotated to drive the pressing block 302 to move to the direction of the face frame 101.

[0048] After the installation is completed, the specific operation is as follows:

[0049] The plurality of lamp beads 104 are powered by the power storage device 205 in the power supply unit 2 at the same time, so that the plurality of lamp beads 104 emit vertical light rays in the direction of the face frame 101. Secondly, the material of the face frame 101 is a light-transmitting material, so the light emitted by the plurality of lamp beads 104 can directly penetrate the face frame 101 and directly downward light emitting to the indoor environment, thereby achieving the purpose of illumination. Then manually rotate the end of the screw rod extending outside the face frame 101, so that the screw rod rotates inside the fixed support 301. Under the cooperation of the anti-slip nut, the screw rod is always located inside the fixed support 301 and will not come off the fixed support 301. In this way, the pressing plate will move towards the face frame 101. Since the pressing block 302 is located outside the face frame 101, when the pressing block 302 moves to the vicinity of the face frame 101, it will contact and apply pressure to the side extension plate of the ceiling inner wall, and cooperate with the screw and nut on the face frame 101 to achieve double fixation of the face frame 101, so that it is not easy to displace or fall off due to the rocking of the hull, causing certain safety hazards.

[0050] Embodiment 2

[0051] According to the discovery in Embodiment 1, although the rocking of the face frame 101 and the light source rear cover 102 and other components can be prevented by rotating the screw rod and driving the pressing block 302 to move downward and press the side of the ceiling, but since the contact area of the pressing block 302 with the ceiling is small, if the rocking intensity is too high due to the sea waves or wind waves, the extension plate on the ceiling in contact with the pressing block 302 will be locally deformed, and in severe cases, the pressing block 302 will be easily detached from the edge of the ceiling, thereby causing the lamp to fall off and causing certain safety hazards. Secondly, since the face frame 101, the light source rear cover 102, the power supply unit 2 and the ceiling are installed in an embedded manner, during normal use of the lamp, the power storage device 205 in the power supply unit 2 will generate high temperature during normal power supply, and a large amount of heat will be generated during the conversion of electric energy and light energy. If the power supply unit 2 is not cooled in time, the accumulation of heat in the power supply unit 2 will cause the power supply unit 2 to short circuit or the lamp to short circuit and be damaged. Based on this, Embodiment 2 is proposed, and the specific adjustment steps are as follows:

[0052] The outer side of the power lower shell 213 is provided with a ventilation system, and the ventilation system comprises an air inlet bin 207 and an air outlet bin 209, the interiors of the air inlet bin 207 and the air outlet bin 209 are each provided with a conveying pipe 210, the conveying pipe 210 is connected with the side of the face frame 101 facing the power supply unit 2, the bottom of the face frame 101 is provided with a plurality of ventilation holes on the left side and the right side, the interior of the conveying pipe 210 of the air inlet bin 207 is provided with a micro air pump 208, a communication groove is arranged between the air inlet bin 207 and the power lower shell 213, the number of the communication grooves is two, and the communication grooves are symmetrically arranged on the left side and the right side of the power lower shell 213, the air inlet bin 207 and the air outlet bin 209 are in communication with the left side and the right side of the power lower shell 213 through the two communication grooves, the air inlet bin 207 is provided with a first filter plate 214 and a second filter plate 215, the first filter plate 214 and the second filter plate 215 are slidingly arranged in the communication grooves close to the air inlet bin 207, the first filter plate 214 and the second filter plate 216 are provided with an electromagnet 216 between the first filter plate 214 and the second filter plate 216 and the communication groove, one side of the inner wall of the communication groove away from the electromagnet 216 is provided with a return spring, the return spring can reset the first filter plate 214 and the second filter plate 215 when the electromagnet 216 is not in a working state, one side of the first filter plate 214 and the second filter plate 215 facing the electromagnet 216 is provided with a magnetic block corresponding to the electromagnet 216, a temperature sensor is arranged in the middle of the power lower shell 213, and the temperature sensor is used for detecting the temperature data of the middle region of the power lower shell 213 in real time, if the temperature sensor detects that the temperature data in the power lower shell 213 is higher than a preset value, the micro air pump 208 is started, and the micro air pump 208 cooperates with the conveying pipe 210 to convey external gas to the interior of the air inlet bin 207 through the ventilation holes in the bottom of the face frame 101, when the gas enters the interior of the air inlet bin 207, the gas rapidly flows to one side of the first filter plate 214 and the second filter plate 215, then passes through the filter holes in the first filter plate 214 and the second filter plate 215 to enter the interior of the power lower shell 213, and flows to the direction of the power storage unit and the air outlet bin 209, in this process, the flowing gas can carry the heat generated by the power storage device 205, enter the interior of the air outlet bin 209, then be discharged outward from the ventilation hole on one side of the face frame 101 through the cooperation of the air outlet bin 209 and the conveying pipe 210, so that the internal of the power supply unit 2 is ventilated and cooled.

[0053] After the above adjustment scheme, continue to use the temperature sensor to detect the temperature inside the power supply unit 2, if the detected temperature data is still higher than the preset value, control the micro air pump 208 to increase the suction power, and through the delivery pipe 210 and the multiple ventilation holes under the face frame 101, the external air is sucked into the inside of the air inlet chamber 207, then the electromagnet 216 on one side of the first filter plate 214 generates a magnetic force on the magnetic block on the first filter plate 214, so that the first filter plate 214 slides inside the communication groove, at this time the filter holes on the first filter plate 214 and the second filter plate 215 are in a dislocation state, and it is ensured that the gas can still pass through the first filter plate 214 and the second filter plate 215, because the first filter plate 214 and the second filter plate 215 are in a dislocation state, therefore the diameter of the multiple filter holes will gradually decrease due to the dislocation of the first filter plate 214 and the second filter plate 215, so the resistance of the airflow passing through is increased, at this time the micro air pump 208 works at high power, so that the air pressure in the air inlet chamber 207 is increased, combined with the reduction of the diameter, the effect of the filter press is realized, so that the temperature of the airflow passing through the first filter plate 214 and the second filter plate 215 is rapidly reduced, thereby realizing the effect of cooling the power supply unit 2.

[0054] After the above adjustment scheme, the temperature sensor continues to detect the temperature data in the power supply unit 2, if the temperature has dropped, but is still higher than the preset value, it is judged that the surface filter holes of the first filter plate 214 and the second filter plate 215 accumulate impurities in the ventilation process, causing the gas flow to decrease, at this time the micro air pump 208 is controlled to be in a high-power blowing state, then the electromagnet 216 on one side of the first filter plate 214 and the second filter plate 215 drives the first filter plate 214 and the second filter plate 215 to perform interlaced reciprocating motion inside the communication groove, when the first filter plate 214 and the second filter plate 215 are in reciprocating interlaced motion, friction and vibration will be generated (for details, please refer to Figure 8 ), therefore the dust or impurities attached to the surface of the first filter plate 214 and the second filter plate 215 can be shaken off, and the micro air pump 208 blows at high power at this time, the gas carrying dust and impurities is discharged outside the face frame 101 through the delivery pipe 210 and the ventilation hole, thereby completing the cleaning effect of the first filter plate 214 and the second filter plate 215, after adjustment, the above adjustment process and working state will continue, and the power supply unit 2 can be continuously cooled.

[0055] Secondly, the adjusting plate 304 is arranged below the pressing block 302, the adjusting plate 304 and the pressing block 302 are provided with a hinged mechanism, the adjusting plate 304 can deflect along the lower side of the pressing block 302 by cooperating with the hinged mechanism, the hinged mechanism is provided with a reset torsion spring, and the adjusting plate 304 can be reset by the reset torsion spring, the adjusting plate 304 and the hinged mechanism are provided in plurality, and each adjusting plate 304 and the hinged mechanism are symmetrically arranged below the pressing block 302, the air bag 305 is arranged between the two adjusting plates 304, one side of the air bag 305 is fixedly arranged on the inner wall of the pressing block 302, and the bottom of the air bag 305 extends to the lower side of the two adjusting plates 304, so that when the surface frame 101 is completed and the pressing block 302 is driven to rotate the screw and tightly contact the ceiling, the bottom of the air bag 305 will first tightly contact the ceiling.

[0056] When the hull is in an extreme situation and generates high-frequency and high-amplitude shaking, since one side of the air bag 305 always tightly contacts the ceiling, the air bag 305 will continuously bear a higher pressure at this time, so that the gas in the air bag 305 flows to the middle of the pressing block 302, secondly, since the air bag 305 always contacts the inner sides of the two adjusting plates 304, the left and right sides of the air bag 305 will be in an inflation deformation state in the process of the gas in the air bag 305 being pressed and flowing upward, so as to extrude the interiors of the two adjusting plates 304, and the two adjusting plates 304 deflect outward under the action of the hinged mechanism below the pressing block 302, and the two adjusting plates 304 after deflection will be in an “eight” shape, and the air bag 305 between the two adjusting plates 304 will contact the ceiling in a large area, and at the same time, the surface of the air bag 305 is pressed by the adjusting plate 304 through the counterforce of the reset torsion spring of the two hinged mechanisms, so that the air bag 305 can always maintain this state when high-frequency and high-amplitude shaking occurs, and since the air bag 305 is made of high-toughness rubber material and has elasticity, the air bag 305 can continuously absorb pressure and shaking, so as to increase the contact area and absorb the pressure generated by high-frequency and high-amplitude shaking, thereby ensuring the stability effect of the surface frame 101, the light source rear cover 102 and the power supply unit 2, and when the hull returns to a stationary state, the air bag 305 will gradually return to the initial state under the action of the elasticity of the air bag 305 and the reset torsion spring of the two adjusting plates 304.
