Description

Technical Field

[0001] The utility model relates to the field of decorative lamps, and more specifically to an LED ceiling lamp. Background Art

[0002] LED ceiling lights utilize a diffused light source, resulting in less glare, a wide illumination area, and a uniform light spot, creating a comfortable lighting environment. They also offer low energy consumption, significantly saving energy compared to traditional lighting fixtures. Their embedded installation method preserves the overall ceiling structure, seamlessly blending in without taking up additional space. These advantages have led to their increasing use in our lives. However, because traditional LED lamps generate heat during the light-emitting process, prolonged exposure to high temperatures can affect the chip, accelerating the degradation of the lamp, and ultimately shortening the lifespan of the LED.

[0003] In order to solve these problems, a new type of LED ceiling light equipment came into being. To this end, we proposed a fan and air guide plate fixedly installed in the middle of the inner part of the LED ceiling light shell. The air guide plate has a hemispherical structure, and the surface of the air guide plate is evenly distributed with air guide holes tilted inward at 45 degrees. The air guide holes gradually gather inward as the hemispherical air guide plate moves inward. The bottom end of the shell is fixed with heat dissipation fins, which are located at the bottom of the air guide plate. The heat dissipation fins have a mesh structure and a large contact area with the air, which can accelerate the heat dissipation of the bottom plate. When the fan switch is turned on, the airflow passes through the air guide plate and reaches the heat dissipation fins. Since the air guide plate has a hemispherical structure, when the wind blows into the interior of the LED lamp, it is guided to disperse to the surroundings through the air guide holes tilted inward at 45 degrees. After the airflow passes through the air guide holes, the wind direction changes, which better disperses the wind to the LED lamp beads, the bottom plate and the heat dissipation fins, playing a good heat dissipation role.

[0004] Therefore, it is necessary to design a new type of LED ceiling lamp that is not prone to fire and other safety accidents. The LED ceiling lamp has a stronger structure, strong vibration and impact resistance, is not easy to damage, and is safer and more reliable to use. Utility Model Content

[0005] The utility model provides an LED ceiling lamp, comprising a ventilation component and a heat dissipation component, wherein the heat dissipation component is installed inside the ventilation component;

[0006] The heat dissipation component includes a shell 1, a fan 8 is fixedly installed at the middle end of the shell 1, an air guide plate 9 is installed inside the shell 1, the air guide plate 9 is installed at the bottom end of the fan 8, the air guide plate 9 has a hemispherical structure, and the surface of the air guide plate 9 is distributed with air guide holes 13 inclined inward at 45°.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model is provided with a fan and an air guide plate fixedly installed at the inner middle end of the shell. The air guide plate has a hemispherical structure. Air guide holes inclined inward at 45° are evenly distributed on the surface of the air guide plate. The air guide holes gradually gather inward as the hemispherical air guide plate moves inward. Heat dissipation fins are fixedly installed at the bottom end of the shell. The heat dissipation fins are located at the lower part of the air guide plate. Since the heat dissipation fins have a mesh structure, the contact area with the air is large, which can accelerate the heat dissipation of the bottom plate. When the fan switch is turned on, the airflow passes through the air guide plate and reaches the heat dissipation fins. Since the air guide plate has a hemispherical structure, when the wind blows toward the inside of the LED lamp, the wind is guided to be dispersed around through the air guide holes inclined inward at 45°. After the airflow passes through the air guide holes, the wind direction changes, and the wind is better blown to the LED lamp beads, the bottom plate and the heat dissipation fins, thereby achieving a good heat dissipation effect.

[0016] 2. The utility model drives the upper cover to rotate 90° through a stepper motor fixedly connected at the center of the upper cover. The ball fixedly connected to the bottom end of the upper cover will rotate inside the ball groove on the inner wall of the outer ring of the lower cover. The limiting block inside the ball groove can limit the position of the ball to ensure that the rotation angle of the upper cover is 90°. The stepper motor and the limiting block are controlled to ensure that the rotation angle of the upper cover is 90°. At this time, the partition of the upper cover and the partition of the lower cover become vertical, forming a mesh hole. At this time, there will be an air inlet on the top, and air can enter the lamp body without affecting the normal use of the fan.

[0017] 3. The utility model achieves higher brightness output with lower power consumption. The light-to-electricity conversion efficiency of LED ceiling lamps is higher, and energy consumption is greatly reduced. The life of LED can usually be long and stable under normal use, reducing the trouble and cost of frequent replacement of lamps. It is particularly suitable for places where it is not easy to replace lamps. High-quality LED ceiling lamps can provide uniform and soft light, avoiding possible problems such as uneven brightness and glare, reducing stimulation to the human eye, and improving lighting comfort.

[0025] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0026] Please refer to Figure 1 - Figure 5 The present invention provides an LED ceiling lamp. When powered on, ventilation holes of the same size are evenly opened on the lower side of the housing 1 and arranged in a ring shape, so that the residual wind blown by the fan 8 when it is running can be blown out from the lower side of the housing 1 to avoid the formation of water droplets due to excessive internal temperature.

[0027] The top of the housing 1 is equipped with an upper cover 2, and the bottom of the upper cover 2 is fixedly connected to a ball 5, with a ball 5 distributed every 90 degrees. A stepper motor 4 is fixedly connected to the center of the upper cover 2. The upper inner wall of the housing 1 is fixedly connected to the lower cover 3, which contacts the upper cover 2 below the upper cover 2. A ball groove 6 is opened on the inner wall of the outer ring of the lower cover 3. The inner part of the ball groove 6 is fixedly connected to a limit block 7. Horizontal partitions are evenly distributed inside the upper cover 2 and the lower cover 3. When the upper cover 2 and the lower cover 3 need to be opened, the stepper motor 4 fixedly connected to the center of the upper cover 2 moves forward. The rotation drives the upper cover 2 to rotate 90 degrees. The ball 5 fixedly connected to the bottom end of the upper cover 2 will rotate inside the ball groove 6 on the inner wall of the outer ring of the lower cover 3. The limit block 7 inside the ball groove 6 can limit the position of the ball 5 to ensure that the rotation angle of the upper cover 2 is 90 degrees. The stepping motor 4 and the limit block 7 are controlled to ensure that the rotation angle of the upper cover 2 is 90 degrees. At this time, the position of the partition of the upper cover 2 and the partition of the lower cover 3 becomes perpendicular, and a mesh hole will be formed. At this time, there will be an air inlet on the top, and air can enter the lamp body without affecting the normal use of the fan 8.

[0028] When shielding is required, the stepper motor 4 rotates in the reverse direction, and the position of the partitions of the upper cover 2 and the lower cover 3 becomes horizontal. The width of the partitions of the upper cover 2 is the same as the width of the gap between the partitions of the lower cover 3. The partitions of the upper cover 2 and the lower cover 3 are staggered in the closed state, which can prevent dust and insects from entering the interior of the lamp body and affecting the use of the lamp body, and has both beautiful and practical effects.

[0029] The fan 8 is fixedly installed at the middle end of the interior of the shell 1, and an air guide plate 9 is installed inside the shell 1. The position of the air guide plate 9 is at the bottom end of the fan 8. The air guide plate 9 has a hemispherical structure. The surface of the air guide plate 9 is evenly distributed with air guide holes 13 inclined inwardly at 45 degrees. The air guide holes 13 gradually gather inwardly as the hemispherical air guide plate 9 is hemispherical. The bottom end of the shell 1 is fixedly installed with heat dissipation fins 10. The position of the heat dissipation fins 10 is fixedly installed at the lower part of the air guide plate 9. The heat dissipation fins 10 have a mesh structure and a large contact area with the air, which can accelerate the heat dissipation of the bottom plate 11. When the fan 8 is turned on, the airflow passes through the air guide plate 9 and reaches the heat dissipation fins 10. Since the air guide plate 9 has a hemispherical structure, when the wind blows toward the inside of the LED lamp, the wind is guided to be dispersed around by the air guide holes 13 inclined inwardly at 45 degrees. After the airflow passes through the air guide holes 13, the wind direction changes, and the wind is better blown to the LED lamp beads 12, the bottom plate 11 and the heat dissipation fins 10, thereby achieving a good heat dissipation effect.

[0030] The bottom end of the heat dissipation fin 10 is fixedly installed with a base plate 11, and the bottom end of the base plate 11 is fixedly and dispersedly connected with lamp beads 12. Since the LDE lamp beads 12 generate a lot of heat energy when emitting light, the heat energy will cause the temperature of the lamp beads 12 to rise, damage the chip and reduce the service life of the LED ceiling lamp.

[0031] To sum up, when the lamp is turned on, the lamp bead 12 generates heat. Since the base plate 11 is fixedly connected to the top of the lamp bead 12, the heat dissipation of the lamp bead 12 will cause the temperature of the base plate 11 to be too high. The base plate 11 itself also has a certain thermal conductivity. Therefore, the stepper motor 4 drives the upper cover 2 to rotate. The stepper motor 4 and the limit block 7 are controlled to ensure the rotation angle of the upper cover 2. The position of the partition of the upper cover 2 and the partition of the lower cover 3 become vertical to form a mesh hole. At this time, the air inlet above will open to allow air to enter the inside of the lamp body. At this time, the fan 8 rotates, and the wind of the fan 8 blows into the wind guide plate 9. The wind guide holes 13 opened inside the wind guide plate 9 disperse the wind to the surroundings, thereby achieving a good heat dissipation effect.

[0032] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
