DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 to Figure 4 An LED indoor lighting fixture shown includes a lamp tube 1, and a lighting component 2 is fixedly arranged inside the lamp tube 1. The lighting component 2 includes a circuit board and LED lamp beads and other structures, which play the role of indoor lighting. A square box 3 is fixedly connected to the outer wall of the lamp tube 1, and a wind pump 7 is fixedly connected to the inside of the square box 3. The air outlet end of the wind pump 7 is connected to a first air duct 8 through a three-way joint. The end of the first air duct 8 away from the wind pump 7 extends to the inside of the lamp tube 1 and is connected to a wind cover 10. The wind cover 10 faces the lighting component 2, and a circular hole 5 is opened through the wall of the lamp tube 1. When the lighting component 2 is heated due to long-term use, the wind pump 7 supplies air to the lighting component 2 through the first air duct 8 and the wind cover 10 to achieve the effect of air supply and heat dissipation; and the gas is discharged from the circular hole 5.

[0025] Considering that the LED indoor lighting fixture is used temporarily, if it is fixedly installed by a bracket or other structure, the installation and disassembly operations are cumbersome, a suction cover 4 for adsorption and positioning is fixedly connected to the side of the square box 3 facing away from the lamp tube 1, and the air inlet end of the air pump 7 is connected to the suction cover 4. The second air duct 12 is connected. The suction cover 4 is attached to the indoor object, and the air pump 7 sucks the inside of the square box 3 through the second air duct 12, so that the inside becomes a negative pressure state, so that the lamp is adsorbed and fixed on the wall, achieving the effect of adsorption and fixing, and improving the use efficiency of the lamp.

[0026] A pressure sensor may be provided inside the suction hood 4 to monitor the suction pressure.

[0027] In order to improve the sealing effect of the suction cover 4, a sealing ring 6 is fixedly embedded on the side of the suction cover 4 facing away from the square box 3, and the sealing ring 6 abuts against the indoor object.

[0028] By arranging structures such as the air pump 7, the first air duct 8, the air cover 10 and the suction cover 4, the effects of air supply, heat dissipation and adsorption fixation are achieved at the same time, thereby improving the use efficiency of the lamp.

[0029] It should be noted that indoor objects can be smooth objects such as glass and tiles.

[0030] The first solenoid valve 9 is fixedly mounted on the first air duct 8, and the second solenoid valve 13 is fixedly mounted on the second air duct 12. A temperature sensor 17 is fixedly connected to the inside of the lamp tube 1, and a controller 18 is fixedly mounted on the inner wall of the square box 3, and the temperature sensor 17 cooperates with the controller 18. Specifically, the controller 18 is connected between the temperature sensor 17 and the first solenoid valve 9. When the temperature sensor 17 detects that the temperature at the lighting component 2 exceeds the set threshold, the first solenoid valve 9 is opened through the controller 18, and the air pump 7 supplies air to the lighting component 2 through the first air duct 8 and the air cover 10.

[0031] Considering that the air inlet end of the air pump 7 is connected to the second air duct 12, a pressure-compensating device can be provided on the air inlet end of the air pump 7. The pressure-compensating device includes an air inlet pipe, a control valve and other structures. When the second solenoid valve 13 is closed, the gas can be sucked by the pressure-compensating device and air is supplied to the lighting component 2 through the first air duct 8 and the wind hood 10. The pressure-compensating device is an existing common technology and will not be elaborated here.

[0032] In addition, a battery may be provided on the square box 3 to supply power to structures such as the air pump 7, the first solenoid valve 9 and the second solenoid valve 13.

[0033] An elastic strip 11 is fixedly connected to the air outlet of the wind cover 10. The elastic strip 11 has an S-shaped structure. When wind is blown out from the wind cover 10, the elastic strip 11 shakes, so that the wind oscillates, expanding the wind coverage area and avoiding always blowing directly on the lighting component 2.

[0034] When the suction cover 4 needs to be removed, a pressure relief pipe 15 is fixedly connected to the suction cover 4, the pressure relief pipe 15 is communicated with the suction cover 4, and a pressure relief valve 16 is fixedly installed on the pressure relief pipe 15. When the pressure relief valve 16 is opened, external air enters the suction cover 4 through the pressure relief pipe 15, which facilitates the removal of the lamp.

[0035] The wall of the square box 3 is provided with an air inlet slot 19, and a filter 14 is fixedly connected to the inside of the air inlet slot 19. External air can enter the inside of the square box 3 through the air inlet slot 19, and the filter 14 filters the dust in the air.
