Description

Technical Field

[0001] This invention relates to the field of LED electrodeless lamp technology, specifically an LED electrodeless lamp with a heat dissipation device. Background Technology

[0002] LED electrodeless lamps are the fourth generation of lighting fixtures and a type of energy-saving lamp. They work by generating plasma radiation ultraviolet light through magnetic field discharge of a high-frequency generator, which then excites phosphors to emit light. LED electrodeless lamps play an important role in the field of lighting fixtures.

[0003] Chinese patent discloses an electrodeless lamp with good heat dissipation (authorization announcement number CN102518973B). This invention can effectively solve the problem of poor heat dissipation in electrodeless lamps in the prior art, which affects the service life of the electrodeless lamp. The key points of its technical solution are: an electrodeless lamp, which includes an electrodeless lamp bulb, a screw base, a front plastic part, a coupler base, a controller heat sink, and a screw base connector. The upper part of the front plastic part is connected to the electrodeless lamp bulb, the lower part of the front plastic part is connected to the upper part of the coupler base, the lower part of the coupler base is connected to the upper part of the controller heat sink, the lower part of the controller heat sink is connected to the screw base connector, and the lower part of the screw base connector is connected to the screw base. This invention enhances the heat dissipation of electrodeless lamps, thereby increasing their lifespan. However, the aforementioned technical solutions rely on a heat sink for heat dissipation, but the LED beads used in these lamps are relatively large, causing them to heat up quickly during illumination. This places a high workload on the heat sink, and the overall heat dissipation of the electrodeless lamp depends entirely on the heat sink, resulting in slow overall cooling speed and a relatively singular cooling method. Furthermore, the lack of separation between the heat dissipation and cooling channels further hinders the cooling rate of the electrodeless lamp. Therefore, those skilled in the art have developed an LED electrodeless lamp with a heat dissipation device to address the problems mentioned in the background section. Summary of the Invention

[0004] The purpose of this invention is to provide an LED electrodeless lamp with a heat dissipation device to solve the problems mentioned in the background art.

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

[0006] An LED electrodeless lamp with a heat dissipation device includes a main lamp tube, a hanger connected to both sides of the main lamp tube for hanging, a connecting mechanism connected to the left and right sides of the main lamp tube, a lamp cover installed on the outside of the main lamp tube, a lamp head installed on the top of the lamp cover, a heat sink installed on the surface of the lamp head for heat dissipation, a flow guiding mechanism fitted into the center of symmetry of the heat sink, and a mounting mechanism fitted into the lower end of the main lamp tube.

[0007] The connecting mechanism includes: a connecting cylinder installed between the main lamp tube and the lamp cover; a heat insulation plate installed inside the connecting cylinder for heat insulation; an isolation plate integrally connected to the surface of the heat insulation plate; a heat dissipation copper column installed on the upper surface of the isolation plate for heat dissipation; and an intake fan located below the isolation plate and fitted into the lower end of the main lamp tube.

[0008] The drainage mechanism includes: an arched cover installed in the middle of the heat sink, a solid heat insulation seat disposed in the middle of the inside of the arched cover, an arc-shaped groove disposed between the solid heat insulation seat and the inner wall of the arched cover, and an outlet fixedly opened on the surface of the arc-shaped groove.

[0009] In one embodiment of the present invention, the mounting mechanism includes: a lamp holder fitted inside the lower end of the main lamp tube, LED beads installed on the surface of the lamp holder for illumination, and a dry ice cooling box fitted at the center of the bottom of the lamp holder.

[0010] In one embodiment of the present invention, a suction fan is installed inside the upper end of the main lamp tube, and a motor is connected to the center line of the suction fan.

[0011] In one embodiment of the present invention, the symmetrical center line of the connecting cylinder coincides with the heat insulation plate, and the upper half of the connecting cylinder is connected to the upper two-thirds of the main lamp tube, while the lower half of the connecting cylinder is connected to the lower remaining one-third of the main lamp tube.

[0012] In one embodiment of the present invention, the main lamp tube is connected to the lamp cover via a connecting tube, and the lamp cover and the connecting tube are symmetrical about the center line of the main lamp tube. The surface of the lamp cover is provided with a light-transmitting cover.

[0013] In one embodiment of the present invention, the upper side wall of the lampshade is provided with a vent, a streamlined plate is inserted and installed inside the vent, and an air inlet is opened at one end of the streamlined plate.

[0014] In one embodiment of the present invention, the air vent and the air inlet are interconnected, and the external structure of the streamlined plate is streamlined and curved.

[0015] In one embodiment of the present invention, the solid heat insulation seat has a hollow center and is narrower at the top and wider at the bottom.

[0016] In one embodiment of the present invention, the arc-shaped groove has an arc-shaped external shape and is connected to the heat sink through an outlet.

[0017] In one embodiment of the present invention, the lamp holder has a conical shape, and the LED beads are distributed in a ring about the center line of symmetry of the lamp holder. The center line of symmetry of the lamp holder coincides with the center line of symmetry of the dry ice cooling box.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The connecting tube connects the main lamp tube to the lamp cover. The connecting tube contains a heat insulation plate, which is connected to an isolation plate. The heat insulation plate divides the interior of the connecting tube into upper and lower layers, while the isolation plate divides the main lamp tube into upper and lower layers. The upper part of the main lamp tube is connected to the suction fan, and the upper half of the main lamp tube is connected to the upper half of the connecting tube. The suction fan can remove heat from the lamp cover through the connecting tube. The intake fan is connected to the lower half of the main lamp tube and the lower half of the connecting tube, blowing in cool air to help dissipate heat from the LED beads inside the lamp cover. The intake and exhaust channels are independent to avoid mutual interference, facilitating heat dissipation and cooling.

[0020] 2. By setting up the main lamp, the lampshade is installed on both sides of the main lamp, thus separating the two sets of LED beads to prevent the LED beads from concentrating together and causing the temperature to rise too quickly when illuminating. The inside of the lampshade is equipped with a conical lamp holder, which disperses the LED beads. This does not affect the lighting function of the LED beads, while also preventing the LED beads from concentrating and causing heat to not dissipate in time. At the same time, a dry ice cooling box is installed at the bottom center of the lamp holder. When the temperature rises, dry ice can be placed in the box to assist in cooling.

[0021] 3. A heat sink is installed on the top of the lampshade, and an arched cover is installed at the symmetrical center of the heat sink. A solid heat insulation seat is set inside the arched cover. The center of the solid heat insulation seat is a hollow structure and is connected to the arc-shaped groove. Heat enters the arc-shaped groove through the center of the solid heat insulation seat and then dissipates through the outlet on the surface of the arc-shaped groove. Heat is dissipated by the heat sink. The arc-shaped groove and the solid heat insulation seat can separate the heat and prevent backflow during the heat dissipation process, which is conducive to heat dissipation and diversion.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 8This invention provides an LED electrodeless lamp with a heat dissipation device, including a main lamp tube 1, a hanger 2 connected to both sides of the main lamp tube 1 for hanging, a connecting mechanism connected to the left and right sides of the main lamp tube 1, and a lamp cover 4 installed on the outside of the main lamp tube 1. The connecting mechanism includes: a connecting tube 3 installed between the main lamp tube 1 and the lamp cover 4, a heat insulation plate 12 installed in the middle of the connecting tube 3 for heat insulation, an isolation plate 13 integrally connected to the surface of the heat insulation plate 12, a heat dissipation copper column 14 installed on the upper surface of the isolation plate 13 for heat dissipation, and an intake fan 15 set below the isolation plate 13 and fitted into the lower end of the main lamp tube 1. The symmetrical center line of the connecting tube 3 coincides with the heat insulation plate 12, and the upper half of the connecting tube 3 is connected to the upper two-thirds of the main lamp tube 1, and the lower half of the connecting tube 3 is connected to the lower remaining one-third of the main lamp tube 1.

[0034] The main lamp tube 1 is connected to the lamp cover 4 through the connecting tube 3. The lamp cover 4 and the connecting tube 3 are symmetrical about the center line of the main lamp tube 1. The surface of the lamp cover 4 is provided with a light-transmitting cover 7. The upper end of the main lamp tube 1 is equipped with a suction fan 101, and the center line of the suction fan 101 is connected to a motor 102.

[0035] Specifically, the lampshade 4 is connected to the main lamp tube 1 via the connecting tube 3, allowing communication between the interior of the lampshade 4 and the main lamp tube 1. The connecting tube 3 transfers heat from the lampshade 4 into the main lamp tube 1. An intake fan 101 and an intake fan 15 are respectively installed inside the upper and lower ends of the main lamp tube 1. The intake fan 101 exhausts heat from the lampshade 4 and the main lamp tube 1, while the intake fan 15 draws external air into the lampshade 4 and the main lamp tube 1, facilitating the cooling of the interior of the lampshade 4. The lampshade 4 is cooled during use. Because the heat insulation plate 12 is set in the middle of the connecting cylinder 3, the heat inside the lampshade 4 will flow into the main lamp 1 from the upper half of the connecting cylinder 3. The upper suction fan 101 of the main lamp 1 rotates under the drive of the motor 102, thereby exhausting the heat inside the main lamp 1. In addition, the intake fan 15 inside the lower end of the main lamp 1 introduces the outside air into the main lamp 1 and flows into the lampshade 4 along the lower half of the connecting cylinder 3, which helps to cool the inside of the lampshade 4.

[0036] Example 2

[0037] The mounting mechanism is fitted and installed inside the lower end of the main lamp tube 1. The mounting mechanism includes: a lamp holder 9 fitted and installed inside the lower end of the main lamp tube 1, an LED lamp bead 10 installed on the surface of the lamp holder 9 for lighting, and a dry ice cooling box 11 fitted and installed at the center of the bottom of the lamp holder 9.

[0038] The lamp holder 9 has a conical shape, and the LED beads 10 are distributed in a ring about the center line of symmetry of the lamp holder 9. The center line of symmetry of the lamp holder 9 coincides with the center line of symmetry of the dry ice cooling box 11.

[0039] Specifically, the LED beads 10 are installed using the lamp holder 9, which has a conical structure. The LED beads 10 are arranged in a ring along the conical lamp holder 9. A dry ice cooling box 11 is installed at the bottom of the lamp holder 9. After the LED beads 10 are used, dry ice can be placed in them to cool them down when they are at a high temperature. During use, the LED beads 10 are installed on the surface of the lamp holder 9. After the LED beads 10 are used, the power is cut off and the light source is turned off. At this time, the surface of the LED beads 10 is at a high temperature. Dry ice is placed in the dry ice cooling box 11. The dry ice cooling box 11 is connected to the center of the bottom of the lamp holder 9 by a threaded structure. The dry ice cooling box 11 can be removed and installed from the bottom of the lamp holder 9. The dry ice is used to assist in cooling the LED beads 10 and can be used for timely emergency cooling.

[0040] Example 3

[0041] The lamp holder 5 is installed on the top of the lamp cover 4, the heat sink 6 is installed on the surface of the lamp holder 5 for heat dissipation, and the flow guiding mechanism is fitted and installed inside the symmetrical center of the heat sink 6. The flow guiding mechanism includes: an arch cover 8 installed in the middle of the heat sink 6, a solid heat insulation seat 801 set in the middle of the inside of the arch cover 8, an arc groove 802 set between the solid heat insulation seat 801 and the inner wall of the arch cover 8, and an outlet 803 fixedly opened on the surface of the arc groove 802.

[0042] The upper side wall of the lampshade 4 is provided with a vent 401, and a streamline plate 402 is installed inside the vent 401. One end of the streamline plate 402 is provided with an air inlet 403.

[0043] The air vent 401 and the air inlet 403 are interconnected. The external structure of the streamlined plate 402 is streamlined and curved. The center of the solid heat insulation seat 801 is hollow and has a narrow top and wide bottom structure. The external shape of the arc groove 802 is arc-shaped and the arc groove 802 is interconnected with the heat sink 6 through the outlet 803.

[0044] Specifically, the heat sink 6 dissipates heat from inside the lampshade 4. An arched cover 8 is installed on top of the lampshade 4, and a solid heat insulation base 801 is installed inside the arched cover 8. The center of the solid heat insulation base 801 is hollow, so heat rises to the top of the lampshade 4 and enters the arc-shaped groove 802 through the center of the solid heat insulation base 801. The heat is then dissipated through the outlet 803 on the surface of the arc-shaped groove 802, and is dissipated by the heat sink 6. At the same time, the streamlined plate 402 is used to draw in and expel natural air. After heat dissipation, the streamlined structure of the streamlined plate 402 allows heat to flow out, which can help dissipate heat inside the lampshade 4. During use, the heat inside the lampshade 4 rises to the top of the lampshade 4, and the air outside the lampshade 4 enters the air hole 401 at one end of the streamlined plate 402. The air is drawn out from the air hole 401 on the other side along the surface of the streamlined plate 402. At the same time, the heat enters the arc groove 802 from the center of the solid heat insulation seat 801, and then dissipates through the outlet 803 opened on the surface of the arc groove 802.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
