Description

Technical Field

[0001] The utility model relates to the technical field of LED downlights, in particular to a dustproof and moisture-proof LED downlight. Background Art

[0002] LED downlight is a kind of lighting fixture that radiates light downwards. It is a directional lighting fixture. Only its opposite side can receive light. The beam angle is spotlight. The light is more concentrated, with a strong contrast between light and dark, which makes the illuminated object more prominent. The working principle of LED downlight is that light is emitted by LED lamp beads, which is reflected and diffused inside the downlight to form a certain beam angle, thereby achieving the lighting effect.

[0003] LED downlights are widely used in indoor lighting places such as shopping malls, offices, factories, and hospitals. Due to the advantages of low heat generation, power saving, long life, and low maintenance cost, LED downlights have been widely used in modern architectural design. The currently available LED downlights, although they have the advantages of low heat generation, power saving, long life, and low maintenance cost.

[0004] However, the existing LED downlights are mostly installed by embedded installation or fixed by an adhesive layer, which makes it impossible to adjust the lighting angle of the LED downlight, resulting in inflexible use. Once installed, secondary disassembly and assembly are difficult, which is not conducive to maintenance. Therefore, a dust-proof and moisture-proof LED downlight is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a dustproof and moisture-proof LED downlight, which solves the problem that the existing LED downlights are mostly installed by embedded installation or fixed by an adhesive layer, so that the lighting angle of the LED downlight cannot be adjusted, resulting in inflexible use, and once the installation is completed, secondary disassembly and assembly is difficult, which is not conducive to maintenance.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dustproof and moisture-proof LED downlight, comprising a mounting frame, an LED lamp and a substrate, wherein an adjustment and disassembly structure is arranged on the outside of the mounting frame;

[0007] The adjustment and disassembly structure includes a rotating shaft rotatably connected to the inner side of the mounting frame, a lamp tube is fixedly connected to the bottom of the rotating shaft, a driving motor is fixedly installed on the left and right sides of the mounting frame, a No. 1 gear is fixedly connected to the output shaft of the driving motor, a No. 2 gear is installed on the outside of the rotating shaft, buckles are fixedly connected to the front, back and left and right sides of the mounting frame, and buckle blocks are fixedly connected to the front, back and left and right sides of the substrate.

[0008] Furthermore, the inner side of the lamp tube is fixedly connected to the outer side of the LED lamp, the interior of the lamp tube is fixedly connected to an electric fan and a radiator, and the outer side of the lamp tube is fixedly connected to a plastic filter.

[0009] Furthermore, a lamp holder is fixedly mounted on the bottom end of the lamp tube, and a transparent panel is fixedly connected to the bottom end of the lamp holder.

[0010] Furthermore, the first gear is meshed with the second gear for transmission, and a protective shell is fixedly connected to the outside of the driving motor.

[0011] Furthermore, the size of the buckle matches that of the buckle block, and the buckle is engaged with the buckle block.

[0012] Furthermore, a positioning hole is provided on the top of the base plate, and weight-reducing grooves are provided on the front and back sides of the lamp tube.

[0013] Furthermore, a signal receiver is fixedly connected to the left side of the mounting frame, and a three-stage switch is fixedly connected to the right side of the mounting frame. Both the signal receiver and the three-stage switch are electrically connected to the drive motor, the LED lamp and the electric fan.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The dust-proof and moisture-proof LED downlight is provided with an adjustment and disassembly structure. When in use, the user only needs to start the driving motor to drive the No. 1 gear to rotate. When the No. 1 gear rotates, it can drive the No. 2 gear meshing with it to reverse, thereby driving the rotating shaft and the lamp tube to rotate through the No. 2 gear. At this time, the inclination angle of the lamp tube can be adjusted, thereby changing the lighting angle. At the same time, through the cooperation of the buckle and the buckle block, when the LED lamp fails, the maintenance personnel do not need to disassemble the entire lamp, but only need to release the clamping and fixing of the buckle and the buckle block to quickly pull the lamp tube out of the bottom of the base plate for maintenance. After the maintenance is completed, the top of the mounting frame is against the bottom of the base plate, and then the buckle is clamped to the outside of the buckle block for clamping and fixing, thereby performing quick installation. Compared with the existing LED downlight, the lighting angle can be adjusted and the disassembly and assembly are convenient. It is more flexible to use and more conducive to maintenance.

[0016] 2. The dustproof and moisture-proof LED downlight achieves the effects of heat dissipation, dustproof and moisture-proof through the cooperation of an electric fan, a radiator and a plastic filter. When the LED lamp emits light and generates heat, the electric fan can introduce outside air into the interior of the lamp tube. At this time, the radiator can concentrate the wind direction, and the plastic filter can prevent a large amount of dust from entering, thereby fully dissipating the heat of the LED lamp. When the air is relatively humid, the user only needs to adjust the wind direction of the electric fan, changing it from blowing inwards to blowing outwards, so that the humid air near the plastic filter can be blown away through the outward airflow to prevent humid air from entering the interior of the lamp tube.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] See also Figure 1-3 In this embodiment, a dustproof and moisture-proof LED downlight comprises a mounting frame 1, an LED lamp 2 and a substrate 3. The mounting frame 1 is provided with an adjustment and disassembly structure on the outside;

[0023] The adjustment and disassembly structure includes a rotating shaft 4 rotatably connected to the inner side of the mounting frame 1, a lamp tube 5 is fixedly connected to the bottom of the rotating shaft 4, a driving motor 6 is fixedly installed on the left and right sides of the mounting frame 1, a No. 1 gear 7 is fixedly connected to the output shaft of the driving motor 6, a No. 2 gear 8 is installed on the outside of the rotating shaft 4, a buckle 9 is fixedly connected to the front, back and left and right sides of the mounting frame 1, and a buckle block 10 is fixedly connected to the front, back and left and right sides of the base plate 3. When in use, the user only needs to start the driving motor 6 to drive the No. 1 gear 7 to rotate, wherein, when the No. 1 gear 7 rotates, it can drive the No. 2 gear 8 meshing with it to reverse, thereby driving the rotating shaft 4 and the lamp tube 5 to rotate through the No. 2 gear 8. At this time, the inclination angle of the lamp tube 5 can be adjusted, thereby changing the illumination angle.

[0024] At the same time, through the cooperation between the buckle 9 and the buckle block 10, when the LED lamp 2 fails, the maintenance personnel do not need to disassemble the entire lamp 2. They only need to release the clamping and fixing of the buckle 9 and the buckle block 10 to quickly pull the lamp tube 5 out from the bottom end of the substrate 3 for maintenance. After the maintenance is completed, the top of the mounting frame 1 is against the bottom of the substrate 3, and then the buckle 9 is clamped to the outside of the buckle block 10 to be clamped and fixed, so as to be quickly installed. Compared with the existing LED downlights, the lighting angle can be adjusted and the disassembly and assembly are convenient, which is more flexible to use and more conducive to maintenance.

[0025] Among them, the inner side of the lamp tube 5 is fixedly connected to the outer side of the LED lamp 2, the inside of the lamp tube 5 is fixedly connected with an electric fan 11 and a radiator 12, and the outside of the lamp tube 5 is fixedly connected with a plastic filter 13. Through the cooperation of the electric fan 11, the radiator 12 and the plastic filter 13, the effects of heat dissipation, dust and moisture prevention are achieved.

[0026] When the LED lamp 2 emits light and generates heat, the electric fan 11 can introduce external air into the interior of the lamp tube 5. At this time, the radiator 12 can concentrate the wind direction, and the plastic filter 13 can prevent a large amount of dust from entering, thereby fully dissipating the heat of the LED lamp 2. When the air is relatively humid, the user only needs to adjust the wind direction of the electric fan 11 from blowing inward to blowing outward, thereby using the outward airflow to blow away the humid air near the plastic filter 13 to prevent humid air from entering the interior of the lamp tube 5.

[0027] It should be noted that a lamp holder 14 is fixedly installed at the bottom end of the lamp tube 5, a transparent panel 15 is fixedly connected to the bottom end of the lamp holder 14, the number one gear 7 is meshed with the number two gear 8 for transmission, a protective shell is fixedly connected to the outside of the driving motor 6, the size of the buckle 9 matches that of the buckle block 10, and the buckle 9 is snap-connected with the buckle block 10.

[0028] It should be understood that a positioning hole 16 is provided on the top of the substrate 3, and weight-reducing grooves 17 are provided on the front and back of the lamp tube 5. Through the cooperation of the substrate 3 and the positioning hole 16, it is convenient for the staff to install the LED downlight to any position, such as the ceiling or wall, by bolts.

[0029] In addition, a signal receiver 18 is fixedly connected to the left side of the mounting frame 1, and a three-stage switch 19 is fixedly connected to the right side of the mounting frame 1. The signal receiver 18 and the three-stage switch 19 are both electrically connected to the drive motor 6, the LED lamp 2 and the electric fan 11. Through the cooperation of the signal receiver 18 and the three-stage switch 19, when the LED downlight is installed in a position that is not easily accessible, the user can remotely control it through a remote control. When the LED downlight is installed in a position that is easy to reach, the user can manually control it through the three-stage switch 19, which is more convenient to use.

[0030] The working principle of the above embodiment is:

[0031] When in use, the user only needs to start the driving motor 6 to drive the No. 1 gear 7 to rotate, wherein when the No. 1 gear 7 rotates, it can drive the meshing transmission No. 2 gear 8 to reverse, thereby driving the rotating shaft 4 and the lamp tube 5 to rotate through the No. 2 gear 8. At this time, the inclination angle of the lamp tube 5 can be adjusted, thereby changing the lighting angle. At the same time, through the cooperation of the buckle 9 and the buckle block 10, when the LED lamp 2 fails, the maintenance personnel do not need to disassemble the entirety, but only need to release the clamping and fixing of the buckle 9 and the buckle block 10 to quickly pull the lamp tube 5 out of the bottom end of the substrate 3 for maintenance. After the maintenance is completed, the top of the mounting frame 1 is against the bottom of the substrate 3, and then the buckle 9 is clamped to the outside of the buckle block 10 for clamping and fixing, thereby performing quick installation.
