Description

Technical Field

[0001] This utility model relates to the field of LED downlight technology, and in particular to a high energy-saving LED downlight. Background Technology

[0002] LED downlights are recessed ceiling-mounted lighting fixtures that project light downwards. They are suitable for areas requiring uniform illumination, such as bedrooms, living rooms, and bathrooms. LED downlights offer advantages such as energy saving, low carbon footprint, good color rendering, and fast response time.

[0003] An existing energy-saving LED downlight (publication number: CN207815033U) uses a device that places and fixes the LED driver power supply in a suitable power connection position, while the power cord is tightened by the rotation of the shaft. This effectively avoids long cables accumulating in the wire groove. Although the corresponding power cord can be quickly located for later maintenance, after the LED downlight is installed and fixed on the ceiling, it is inconvenient for the user to quickly disassemble and remove the lamp body when it malfunctions, which still affects the efficiency of subsequent maintenance. Furthermore, the heat dissipation effect of the lamp body is not ideal during use, which will shorten the lifespan of the lamp body and affect the energy-saving effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly energy-efficient LED downlight.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-energy-saving LED downlight includes a mounting plate, a slot plate, a lampshade, and an LED lamp body. The slot plate is fitted into the mounting plate. The mounting plate has an inner groove. An inner threaded sleeve is fixedly installed at the outer end of the inner groove. A screw is movably installed on the inner threaded sleeve and threadedly connected to the inner threaded sleeve. A movable block is movably installed inside the inner groove. One end of the screw is connected to the movable block via a rotating shaft. A locking block is fixedly installed at the bottom end of the movable block. The LED lamp body is installed inside the lampshade by fasteners. A heat dissipation vent is opened on the side wall of the lampshade. A fixing frame is fixedly installed on the inner wall of the lampshade near the heat dissipation vent. Heat dissipation aluminum fins are provided on the fixing frame and are evenly distributed on the fixing frame.

[0007] As a further embodiment of this utility model, the card blocks are symmetrically distributed on the mounting plate, and the card blocks are fitted into and connected to the card slot plate.

[0008] As a further embodiment of this utility model, an external threaded pipe is fixedly installed at the outer end of the heat dissipation port, and a sleeve is provided on the external threaded pipe.

[0009] As a further embodiment of this utility model, the sleeve is threadedly connected to the external threaded pipe, and a filter screen is fixedly installed on the sleeve.

[0010] As a further embodiment of this utility model, the filter screens are symmetrically distributed on the lampshade, and the top of the lampshade is fixedly connected to the slot plate.

[0011] As a further embodiment of this utility model, a transparent lamp cover is provided at the bottom of the lampshade, and the transparent lamp cover is threadedly connected to the outer wall of the lampshade.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the LED light body needs to be installed, the mounting plate can be pre-fixed in the desired installation position. The user can initially position the LED light body by pushing the slot plate and engaging the bottom of the mounting plate. Then, turn the screw on one side clockwise. With the cooperation of the inner screw sleeve, the screw pushes the movable block to slide inward into the inner groove. At the same time, the movable block drives the locking block to move closer to the side wall of the slot plate. The mounting plate has two sets of locking blocks, which engage and fix the slot plate on the mounting plate. Then, the LED light body is installed on the mounting plate. When the LED light body malfunctions, the user only needs to turn the screw counterclockwise to slide the movable block outward and move the locking block. After the two sets of locking blocks separate from the slot plate, the entire LED light body can be removed from the mounting plate for easy maintenance and improved ease of use.

[0014] 2. Heat dissipation vents are provided on both sides of the lampshade. These vents allow for ventilation and heat dissipation of the internal LED lamp body. In conjunction with multiple sets of heat sinks, the heat generated by the LED lamp body is expelled from the vents more quickly, thereby reducing the heat generated during operation and saving energy. The filter screen prevents external dust from entering the lampshade, minimizing its impact on the LED lamp body. Furthermore, the user can remove the filter screen by rotating the sleeve to separate it from the external threaded tube, allowing for individual cleaning and improving practicality.

[0024] Reference Figures 1-5A high-energy-saving LED downlight includes a mounting plate 1, a slot plate 2, a lampshade 3, and an LED lamp body 4. The slot plate 2 is fitted into and connected to the mounting plate 1. The mounting plate 1 has an inner groove 302. An inner threaded sleeve 203 is fixedly installed at the outer end of the inner groove 302. A screw 301 is movably installed on the inner threaded sleeve 203. The screw 301 is threadedly connected to the inner threaded sleeve 203. A movable block 303 is movably installed inside the inner groove 302. One end of the screw 301 is connected to the movable block 303 through a rotating shaft. A locking block 202 is fixedly installed at the bottom end of the movable block 303. The LED lamp body 4 is installed inside the lampshade 3 by fasteners. A heat dissipation vent 104 is opened on the side wall of the lampshade 3. A fixing frame 106 is fixedly installed on the inner wall of the lampshade 3 near the heat dissipation vent 104. Heat dissipation aluminum fins 201 are provided on the fixing frame 106 and are evenly distributed on the fixing frame 106.

[0025] In use, the user can pre-fix the mounting plate 1 to the desired installation position of the LED lamp body 4. After the slot plate 2 is engaged with the bottom of the mounting plate 1, the LED lamp body 4 is initially positioned. Then, turn the screw 301 clockwise. With the cooperation of the inner screw sleeve 203, the screw 301 pushes the movable block 303 to slide inward into the inner groove 302. At the same time, the movable block 303 drives the locking block 202 to move closer to the side wall of the slot plate 2. The mounting plate 1 is provided with two sets of locking blocks 202. The slot plate 2 is engaged and fixed on the mounting plate 1 by the two sets of locking blocks 202, and then the LED lamp body 4 is installed on the mounting plate 1. When the LED lamp body 4 malfunctions, the user only needs to turn the screw 301 counterclockwise to make the movable block 303 slide outward and move the locking block 202. After the two sets of locking blocks 202 are separated from the slot plate 2, the LED lamp body 4 can be removed from the mounting plate 1 for the user to repair.

[0026] In this embodiment, the card blocks 202 are symmetrically distributed on the mounting plate 1, and the card blocks 202 are fitted into the connecting card slot plate 2.

[0027] During use, heat dissipation vents 104 are provided on both sides of the lamp cover 3. The two sets of heat dissipation vents 104 can ventilate and dissipate heat for the internal LED lamp body 4. At the same time, they work in conjunction with multiple sets of heat dissipation aluminum fins 201 to accelerate the discharge of heat generated by the LED lamp body 4 from the heat dissipation vents 104, thereby reducing the heat generated by the LED lamp body 4 during operation and saving energy. The filter screen 103 can prevent external dust from entering the interior of the lamp cover 3, thereby reducing the impact on the LED lamp body 4. Furthermore, the user can remove the filter screen 103 by rotating the sleeve 102 to separate the sleeve 102 from the external threaded tube 105 for separate cleaning.

[0028] In this embodiment, an external threaded pipe 105 is fixedly installed on the outer end of the heat dissipation port 104, and a sleeve 102 is provided on the external threaded pipe 105.

[0029] In use, two sets of locking blocks 202 are provided on the mounting plate 1, and both sets of locking blocks 202 are "L" shaped. The two sets of locking blocks 202 engage with the slot plate 2, thereby fixing the LED light body 4 on the mounting plate 1.

[0030] In this embodiment, the sleeve 102 is threadedly connected to the external threaded pipe 105, and a filter screen 103 is fixedly installed on the sleeve 102.

[0031] During use, filters 103 are provided on both sets of heat dissipation vents 104. The filters 103 can protect the heat dissipation vents 104 and prevent external dust from entering the interior of the lamp cover 3 and contacting the LED lamp body 4.

[0032] In this embodiment, the filter screens 103 are symmetrically distributed on the lampshade 3, and the top of the lampshade 3 is fixedly connected to the slot plate 2.

[0033] In use, by rotating the sleeve 102, the sleeve 102 can be separated from the external threaded tube 105, thereby driving the filter screen 103 to be disassembled and removed for cleaning.

[0034] In this embodiment, a transparent lamp cover 101 is provided at the bottom of the lampshade 3, and the transparent lamp cover 101 is threadedly connected to the outer wall of the lampshade 3.

[0035] In use, the heat dissipation aluminum fins 201 are mainly made of aluminum. The heat dissipation aluminum fins 201 are evenly distributed at the heat dissipation port 104. Through multiple sets of heat dissipation aluminum fins 201, the heat generated by the LED lamp body 4 can be transferred to the outside faster, thereby enhancing the heat dissipation effect of the LED lamp body 4.

[0036] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the LED lamp body 4 needs to be installed, the mounting plate 1 can be pre-fixed at the position where the LED lamp body 4 needs to be installed. After the user pushes the slot plate 2 to engage with the bottom of the mounting plate 1, the LED lamp body 4 is initially positioned. Then, the screw 301 on one side is turned clockwise. With the cooperation of the inner screw sleeve 203, the screw 301 pushes the movable block 303 to slide inward into the inner groove 302. At the same time, the movable block 303 drives the locking block 202 to move closer to the side wall of the slot plate 2. The mounting plate 1 is provided with two sets of locking blocks 202. The slot plate 2 is engaged and fixed on the mounting plate 1 by the two sets of locking blocks 202, and then the LED lamp body 4 is installed on the mounting plate 1. When the LED lamp body 4 malfunctions, the user only needs to turn the screw 301 counterclockwise to make the movable block 303 slide outward. The movement of the sleeve 202 causes the two sets of sleeves 202 to separate from the slot plate 2, thereby allowing the LED lamp body 4 to be removed from the mounting plate 1 for easy maintenance and improved usability. Heat dissipation vents 104 are provided on both sides of the lamp cover 3, allowing ventilation and heat dissipation for the internal LED lamp body 4. These vents, in conjunction with multiple heat dissipation aluminum fins 201, accelerate the removal of heat generated by the LED lamp body from the vents, reducing the heat generated during operation and saving energy. A filter 103 prevents external dust from entering the lamp cover 3, minimizing its impact on the LED lamp body 4. Furthermore, by rotating the sleeve 102, the user can separate the sleeve 102 from the external threaded tube 105, allowing for easy removal of the filter 103 for cleaning, thus improving practicality.
