Description

Technical Field

[0001] The present invention relates to the technical field of lamps, in particular to LED lamps. Background Art

[0002] LED is a light-emitting diode, a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. Usually, LED lamps need to be equipped with lampshades to assist in installation and use, so LED lamp manufacturers will produce lampshades in pairs;

[0003] LED lamps are usually powered by cables or batteries, which limits the current input to the LED lamps, thus affecting the use of the LED lamps. In addition, the light source area emitted by existing LED lamps is a fixed value, so the LED lamps have only a single irradiation range, which limits the use scenarios of the LED lamps. When the corresponding irradiation area needs to be changed, the LED lamps need to be replaced. Summary of the invention

[0010] Preferably, the cover plate consists of a fixed plate and a movable plate, the movable plate is located above the fixed plate, a No. 2 motor is arranged inside the fixed plate, a driving shaft of the No. 2 motor is connected to a rotating shaft, an end of the rotating shaft away from the fixed plate is connected to the movable plate, and the movable plate is rotatably connected to the fixed plate.

[0011] Preferably, a stretching cloth is arranged between two adjacent fixing plates, and the stretching cloth is made of flexible and opaque rubber. The bottoms of several fixing plates are folded together to form a pointed cone.

[0012] Preferably, a reflective plate is provided on the inner wall of the fixed plate, the side of the fixed plate away from the movable plate is in a triangular shape, and the movable plate is in an arc shape.

[0013] Preferably, a plurality of ventilation pipes are provided inside the fixed body, and the plurality of ventilation pipes are arranged around the axis of the fixed body. The protective cover is a light-transmitting mesh structure. One end of the ventilation pipe is connected to the space between the fixed body and the protective cover, and the other end of the ventilation pipe is connected to the gap between the lampshade and the fixed body. A filter is provided on the side of the ventilation pipe close to the movable plate.

[0014] The staff fixes the end of the fixing body away from the LED component to the ceiling, and then connects the power supply housing to the external power supply, so that the LED lamp is powered on, so that the power supply housing can control the LED component to turn on or off;

[0015] When the light source emission area of ​​the LED lamp is small, the axes of the several cover plates are parallel to the axis of the fixed body, that is, the several cover plates are perpendicular to the ceiling, and a stretch cloth is arranged between two adjacent cover plates, so that the light generated by the LED component is blocked by the lampshade, and the light generated by the LED component can only be emitted along the axis direction of the lampshade. The light generated by the LED component passes through the protective cover and is emitted from the bottom of the fixed body to the side of the protective cover away from the fixed body, thereby realizing the role of the LED lamp as a spotlight;

[0016] When the light source emission area of ​​the LED lamp is large, the controller controls the micro motor on the fixed frame to start, and the driving shaft of the micro motor drives the gear to rotate. When the gear rotates, it meshes with the gear ring in the rotating ring, so that the gear drives the gear ring to rotate, and then the gear ring drives the rotating ring to rotate. When the rotating ring rotates, it drives the fixed plate to rotate, and the fixed plate is inclined to the side away from the movable plate. Since the side of the fixed plate away from the movable plate is in a triangular shape, the ends of several fixed plates away from the movable plate are in contact with each other and combined into a pointed cone shape, and a reflector is provided on the side of the cover plate close to the fixed body, so that the light generated by the LED assembly is reflected by the reflector and the light is reflected onto the ceiling, thereby expanding the area of ​​the light source emission, and the cover plate is in an inclined state after rotation, so that the ends of the cover plate close to the movable plate are separated from each other, thereby causing a gap between two adjacent movable plates, and part of the light generated by the LED assembly can be emitted through the gap between the two adjacent movable plates, further increasing the area of ​​the light source emission;

[0017] When the cover plate is vertical to the ceiling, the light source emission area of ​​the LED component is limited. When the cover plate is rotated and tilted, the light source emission area of ​​the LED component is expanded. Through the rotation of the cover plate, the LED lamp can achieve different light source changes in different scenes, thereby improving the scene adaptability of the LED lamp. At the same time, the LED lamp also has a variety of light source change schemes, which greatly increases the use scenarios of the LED lamp.

[0018] Since the LED components will inevitably generate heat when working for a long time, and the heat will continue to accumulate near the LED lamp. When the light source emission area of ​​the LED lamp is small, the controller controls the No. 2 motor to start, and the driving shaft of the No. 2 motor drives the rotating shaft to rotate, and the rotating shaft drives the movable plate to rotate, so that there is an angle difference between the movable plate and the fixed plate. When several movable plates have completed the rotation, the controller controls the No. 1 motor to start, and the driving shaft of the No. 1 motor drives the transmission wheel to rotate. The transmission wheel contacts the inner wall of the rotating ring, so that the transmission wheel drives the rotating ring to rotate. When the rotating ring rotates, it drives the fixed frame to rotate through the support rod. During the rotation of the fixed frame, the fixed frame drives several fixed plates. The fixed plate rotates, and the fixed plate drives the movable plate to rotate along the axis of the fixed body. Since the movable plate is in an arc shape, it plays the role of a fan blade when rotating, and then the movable plate drives the air disturbance around the LED lamp, thereby generating air flow changes. The air at the bottom of the lampshade flows from the protective cover to the side close to the ceiling. Since the protective cover is a light-transmitting net structure, part of the air passes through the protective cover and enters the space between the protective cover and the LED component, while impurities and dust in the air are blocked by the protective cover, and the filtered air is transported through the ventilation pipe, and finally output through the ventilation pipe close to the side of the movable plate, thereby achieving the effect of heat dissipation and cooling of the LED lamp;

[0019] While the rotating ring drives the movable plate to rotate along the axis of the fixed body, the controller can also control the second motor to rotate continuously, so that the movable plate rotates under the action of the second motor, further increasing the air turbulence, thereby increasing the airflow flowing through the LED component, thereby improving the heat dissipation efficiency of the LED lamp;

[0020] During the gas flow, impurities and dust in the air are blocked by the protective cover, which reduces the surface ventilation efficiency of the protective cover, thereby affecting the heat dissipation efficiency. When the light source emission area of ​​the LED lamp is large, the bottoms of the fixed plates contact and close each other, so that several cover plates form an inverted cone-shaped space. Then the controller controls the No. 1 motor to reverse, so that the air enters the gap between the lampshade and the fixed body from the top of the lampshade, and part of the gas enters through the side of the ventilation pipe close to the movable plate, and then is output from the side of the ventilation pipe close to the protective cover, so that the airflow impacts the protective cover in the opposite direction, so that the dust and impurities attached to the outside of the protective cover fall off, and the fallen dust and impurities fall into the inverted cone-shaped space surrounded by the cover plates, thereby realizing the collection of dust and impurities, avoiding the dust and impurities from being dispersed into the air again with the gas, which not only improves the cleanliness of the protective cover and ensures the normal heat dissipation and cooling of the LED components, but also avoids the dust and impurities from being transported into the air again, thereby improving the air quality around the LED lamp.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0022] 1. When the cover plate is vertical to the ceiling, the light source emission area of ​​the LED component is limited. When the cover plate is rotated and tilted, the light source emission area of ​​the LED component is expanded. Through the rotation of the cover plate, the LED lamp can achieve different light source changes in different scenes, thereby improving the scene adaptability of the LED lamp. At the same time, it also enables the LED lamp to have a variety of light source change schemes, greatly increasing the use scenarios of the LED lamp.

[0023] 2. During the gas flow, impurities and dust in the air are blocked by the protective cover, thereby reducing the surface ventilation efficiency of the protective cover, thereby affecting the heat dissipation efficiency. When the light source emission area of ​​the LED lamp is large, the bottoms of the fixed plates contact and close each other, thereby making several cover plates surround an inverted cone-shaped space. Then the controller controls the No. 1 motor to reverse, thereby allowing air to enter the gap between the lampshade and the fixed body from the top of the lampshade, while part of the gas enters through the side of the vent pipe close to the movable plate, and then is output from the side of the vent pipe close to the protective cover, so that the airflow impacts the protective cover in the opposite direction, thereby causing the dust and impurities attached to the outside of the protective cover to fall off, and the fallen dust and impurities fall into the inverted cone-shaped space surrounded by the cover plates, thereby realizing the collection of dust and impurities, avoiding the dust and impurities from being dispersed into the air again with the gas, thereby improving the cleanliness of the protective cover, ensuring the normal heat dissipation and cooling of the LED components, and avoiding the dust and impurities from being transported into the air again, thereby improving the air quality around the LED lamp.

[0045] As a specific embodiment of the present invention, a plurality of ventilation pipes 12 are arranged inside the fixed body 1, and the plurality of ventilation pipes 12 are arranged around the axis of the fixed body 1. The protective cover 11 is a light-transmitting mesh structure. One end of the ventilation pipe 12 is connected to the space between the fixed body 1 and the protective cover 11, and the other end of the ventilation pipe 12 is connected to the gap between the lampshade 2 and the fixed body 1. A filter is arranged on the side of the ventilation pipe 12 close to the movable plate 25.

[0046] Working principle of the present invention:

[0047] The staff fixes the end of the fixing body 1 away from the LED assembly 13 on the ceiling, and then connects the power supply housing 3 to the external power supply, so that the LED lamp is powered on, so that the power supply housing 3 can control the LED assembly 13 to turn on or off;

[0048] When the light source emission area of ​​the LED lamp is small, the axes of the several cover plates 23 are parallel to the axis of the fixed body 1, that is, the several cover plates 23 are perpendicular to the ceiling, and a stretch cloth 26 is arranged between two adjacent cover plates 23, so that the light generated by the LED component 13 is blocked by the lampshade 2, and the light generated by the LED component 13 can only be emitted along the axis direction of the lampshade 2, and the light generated by the LED component 13 passes through the protective cover 11 and is emitted from the bottom of the fixed body 1 to the side of the protective cover 11 away from the fixed body 1, thereby realizing the role of the LED lamp as a spotlight;

[0049] When the light source emission area of ​​the LED lamp is large, the controller controls the micro motor on the fixing frame 22 to start, and the driving shaft of the micro motor drives the gear to rotate. When the gear rotates, it meshes with the gear ring in the rotating ring 231, so that the gear drives the gear ring to rotate, and then the gear ring drives the rotating ring 231 to rotate. When the rotating ring 231 rotates, it drives the fixed plate 24 to rotate, and the fixed plate 24 is inclined to the side away from the movable plate 25. Since the side of the fixed plate 24 away from the movable plate 25 is in a triangular shape, the ends of several fixed plates 24 away from the movable plate 25 are in contact with each other and combined into a pointed cone shape, and a reflector is provided on the side of the cover plate 23 close to the fixed body 1, so that the light generated by the LED assembly 13 is reflected by the reflector and the light is reflected to the ceiling, thereby expanding the emission area of ​​the light source, and the cover plate 23 is in an inclined state after rotation, so that the ends of the cover plate 23 close to the movable plate 25 are separated from each other, thereby causing a gap between two adjacent movable plates 25, and part of the light generated by the LED assembly 13 can be emitted through the gap between the two adjacent movable plates 25;

[0050] Since the LED assembly 13 will inevitably generate heat when working for a long time, and the heat will continuously accumulate near the LED lamp, when the light source emission area of ​​the LED lamp is small, the controller controls the No. 2 motor to start, and the driving shaft of the No. 2 motor drives the rotating shaft to rotate, and the rotating shaft drives the movable plate 25 to rotate, so that there is an angle difference between the movable plate 25 and the fixed plate 24. When several movable plates 25 have completed rotation, the controller controls the No. 1 motor to start, and the driving shaft of the No. 1 motor drives the transmission wheel to rotate, and the transmission wheel contacts the inner wall of the rotating ring 21, so that the transmission wheel drives the rotating ring 21 to rotate, and when the rotating ring 21 rotates, it drives the fixed frame 22 to rotate through the support rod. During the rotation of the fixed frame 22, the fixed frame 22 drives several fixed plates 24 to rotate. When the LED lamp is rotated, the fixed plate 24 drives the movable plate 25 to rotate along the axis of the fixed body 1. Since the movable plate 25 is in an arc shape, it plays the role of a fan blade when it rotates, and then the movable plate 25 drives the air disturbance around the LED lamp, thereby generating air flow changes. The air at the bottom of the lampshade 2 flows from the protective cover 11 to the side close to the ceiling. Since the protective cover 11 is a light-transmitting net structure, part of the air passes through the protective cover 11 and enters the space between the protective cover 11 and the LED assembly 13, while impurities and dust in the air are blocked by the protective cover 11, and the filtered air is transported through the vent pipe 12, and finally output through the side of the vent pipe 12 close to the movable plate 25, thereby achieving the effect of heat dissipation and cooling of the LED lamp.

[0051] While the rotating ring 21 drives the movable plate 25 to rotate along the axis of the fixed body 1, the controller can also control the second motor to rotate continuously, so that the movable plate 25 rotates under the action of the second motor, further increasing the turbulence of the air, thereby increasing the airflow rate flowing through the LED assembly 13;

[0052] During the gas flow, impurities and dust in the air are blocked by the protective cover 11, thereby reducing the surface ventilation efficiency of the protective cover 11, thereby affecting the heat dissipation efficiency. When the light source emission area of ​​the LED lamp is large, the bottoms of the fixing plates 24 contact each other and close together, thereby making several cover plates 23 surround an inverted cone-shaped space. Then the controller controls the No. 1 motor to reverse, thereby making the air enter the gap between the lampshade 2 and the fixed body 1 from the top of the lampshade 2, and part of the gas enters through the side of the vent pipe 12 close to the movable plate 25, and then is output from the side of the vent pipe 12 close to the protective cover 11, so that the airflow impacts the protective cover 11 in the reverse direction, thereby making the dust and impurities attached to the outside of the protective cover 11 fall off, and the fallen dust and impurities fall into the inverted cone-shaped space surrounded by the cover plates 23, thereby realizing the collection of dust and impurities, and preventing the dust and impurities from floating into the air again with the gas.
