BACKGROUND

LED (Light Emitting Diode) is a semiconductor electronic component that converts electrical energy into light energy. With the continuous development of the LED technology, LED lamps are widely used in various fields such as indicator, display, backlight, general lighting, and the like due to their characteristics such as energy saving, long life, low power consumption, easy maintenance and the like.
The existing LED lamp mainly includes an LED lighting module, a driving circuit, a heat dissipating component and lamp electrodes. The lamp electrodes are connected to the driving circuit, so that the external power source supplies power to the driving circuit through the lamp electrodes. The driving circuit is connected to the LED lighting module to drive the LED lighting module to emit light. The LED lighting module generates heat during the light emission process, and the heat dissipating component dissipates the heat generated by the LED lighting module to the surrounding air, thereby preventing the LED lighting module from being overheated.
However, most existing LED lamps are bulky and difficult to install in practical applications. Some smaller LED light lamps, because of the limitation of heat dissipation, cannot achieve higher power and luminous flux of the LED light sources.

DESCRIPTION OF EMBODIMENTS
The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings. It is obvious that the described embodiments are only part in some embodiments of the present disclosure, but not all embodiments. All other embodiments obtained by those skilled in the art according to the embodiments of the present disclosure without creative efforts are within the protection scope of the present disclosure.
The LED lamp provided in the present disclosure is configured with an insulated heat dissipation pipe, an insulated heat dissipation end, and at least one LED lighting module, so that the LED lamp has a compact structure, which simplifies the installation and assembly process of the LED lamp, reduces the number of parts, and facilitates management. In addition, the LED lamp end (e.g., the insulated heat dissipation end) is set as a heat sink, which can increase the heat dissipation area and address the heating problem of high-power LED lamps.
The technical solutions of the present disclosure are described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
FIG. 1 illustrates a structural diagram of an exploded view of an LED lamp of Embodiment 1 consistent with the disclosed embodiments. As shown in FIG. 1, the LED lamp includes an insulated heat dissipation pipe 20, an insulated heat dissipation end 10, and at least one LED lighting module 30 disposed on or around the outer wall of the insulated heat dissipation pipe 20. A first end 210 of the insulated heat dissipation pipe 20 has an opening 230. The insulated heat dissipation end 10 is configured to cover the opening 230. The insulated heat dissipation end 10 and a second end 220 of the insulated heat dissipation pipe 20 are provided with lamp electrodes 101 and 102.
In some embodiments, the insulated heat dissipation pipe 20 is a one-piece component. The first end 210 of the insulated heat dissipation pipe 20 has an opening 230, the second end 220 of the insulated heat dissipation pipe 20 is closed. The inner side of the second end 230 of the insulated heat dissipation pipe 20 is provided with an electrical connector. The electrical connector is conductive and can facilitate electrical connection, and can be made of metal (e.g., a metal sheet) . The electrical connector can be connected to the second lamp electrode 102 disposed on the outer side of the second end 230 of the insulated heat dissipation pipe 20. Similarly, one side (e.g., inner side) of the insulated heat dissipation end 10 is also provided with an electrical connector. The electrical connector can be connected to the first lamp electrode 101 disposed on the outer side of the insulated heat dissipation end 10.
Further, the LED lamp in some embodiments further includes a driving circuit 40 electrically connected to both the lamp electrodes and the LED lighting module 30. The driving circuit 40 converts the alternating current of the external power grid into the direct current required by the LED lighting module 30, to drive the LED lighting module 30 to emit light.
Specifically, as shown in FIG. 1, the LED lamp in some embodiments includes an insulated heat dissipation pipe 20, an LED light emitting module 30, a driving circuit 40, an insulated heat dissipation end 10, and two positive and negative lamp electrodes (e.g., the first lamp head electrode 101 and the second lamp electrode 102) . The insulated heat dissipation pipe 20 has a hollow inner space (e.g., circuit component (s) may be placed on the inner side of the pipe) . The LED lighting module 30 is disposed on the outer wall of the insulated heat dissipation pipe 20. The first end 210 of the insulated heat dissipation pipe 20 has an opening 230. The insulated heat dissipation end 10 is configured to cover the opening 230 of the first end 210 of the insulated heat dissipation pipe 20. The first lamp electrode 101 is disposed on the insulated heat dissipation end 10, specifically on one side (e.g., outer side) of the insulated heat dissipation end 10 opposite to the side contacting the opening 230. The first lamp electrode 101 is connected to the electrical connector on one side (e.g., inner side) of the insulated heat dissipation end 10. The second lamp electrode 102 is disposed on the second end of the insulated heat dissipation pipe 10, specifically disposed on the outer side of the second end 220 of the insulated heat dissipation pipe 20. The second lamp electrode 102 is connected to the electrical connector on the inner side of the second end 220 of the insulated heat dissipation pipe 20. In addition, the electrical connector on the insulated heat dissipation end 10 is connected to one terminal of the driving circuit 40. The electrical connector on the inner side of the second end 220 of the insulated heat dissipation pipe 20 is connected to another terminal of the driving circuit 40. The first lamp electrode 101 and the second lamp electrode 102 are exposed to connect to an external power source.
In practical applications, the first lamp electrode 101 and the second lamp electrode 102 are connected to the external power source (e.g., respectively connected to a hot line and a neutral line) . The first lamp electrode 101 and the second lamp electrode 102 transfer external electric energy (e.g., from power grid) to the driving circuit 40, and the driving circuit 40 drives the LED lighting module 30 to emit light. The LED lighting module 30 generates heat during the light emission process. Since the LED lighting module 30 is in direct contact with the insulated heat dissipation pipe 20, the heat generated by the LED lighting module 30 can be directly transferred to the insulated heat dissipation pipe 20. The insulated heat dissipation pipe 20 is in contact with the insulated heat dissipation end 10, and the heat on the insulated heat dissipation pipe 20 can be transferred to the insulated heat dissipation end 10 and the second end 220 of the insulated heat dissipation pipe 20. That is, the heat dissipation area is increased comparing to conventional lamp that only uses a heat sink. The insulated heat dissipation end 10 and the insulated heat dissipation pipe 20 quickly dissipate heat into the air, thereby improving the heat dissipating speed of the LED lamp. The problem that the heat cannot be dissipated in time to cause the LED lighting module 30 or the driving circuit 40 to be burned out is avoided, so that the in-use reliability and service life of the LED lamp are improved.
Further, one end of the LED lamp and the insulated heat dissipation pipe are integrated as a one-piece part, i.e., the insulated heat dissipation pipe 20, and the other end of the LED lamp is the insulated heat dissipation end 10, so that the number of parts of the LED lamp can be reduced (that is, instead of making two separate end parts to be connected to two openings of a heat dissipation pipe, which would require 3 pieces of parts, the disclosed LED lamp only needs 2 pieces of parts: one insulated heat dissipation end and one insulated heat dissipation pipe having one opening and one closed end, the closed end of the pipe functions as the end of the LED lamp) , and the in-use reliability of the LED lamp can be improved. The assembly steps of components in manufacturing can be reduced, the production process can be simplified, and the production efficiency of the LED lamp can be improved.
As shown in FIG. 1, the size and shape of the insulated heat dissipation end 10 in some embodiments are compatible with the size and shape of the first end 210 of the insulated heat dissipation pipe 20. The insulated heat dissipation end 10 can cover on the opening 230 of the first end 210 of the insulated heat dissipation pipe 20. For example, the insulated heat dissipation pipe 20 is a circular tube, and the insulated heat dissipation end 10 may have a disk shape. The diameter of the insulated heat dissipation end 10 is the same as the outer diameter of the first end 210 of the insulated heat dissipation pipe 20 (or slightly larger than the outer diameter of the insulated heat dissipation pipe 20) . Thus, after the driving circuit 40 is disposed on the inner side of the insulated heat dissipation pipe 20, the insulated heat dissipation end 10 can just cover the opening 230 of the first end 210 of the insulated heat dissipation pipe 20, so that the driving circuit 40 is located in the inner space of the insulated heat dissipation pipe 20, and the protection of the drive circuit 40 can be achieved.
The insulated heat dissipation pipe 20 of the present embodiment can be manufactured by die casting or 3D printing technology. 3D printing technology can easily realize the manufacture of complex structures, reduce mold development, and lower the investment cost. For LED lamps with high customization requirements and relatively small required quantity, 3D printing can be preferred as the manufacturing manner.
Optionally, in some embodiments, the insulated heat dissipation pipe 20 can be manufactured as a one-piece or integral part by a soldering process. For example, the insulated heat dissipation pipe 20 may be made of plastic, ultrasonic welding, hot plate welding, or the like can be adopted to weld or hot melt a plastic component on the second end 220 of the insulated heat dissipation pipe 20. The second end 220 of the insulated heat dissipation pipe 20 is machined into a closed structure. Accordingly, the number of scraps can be reduced, the yield of finished products can be improved, and resource waste can be reduced.
Optionally, in some embodiments, the insulated heat dissipation end 10 is detachably connected to the first end 210 of the insulated heat dissipation pipe 20.
Specifically, in some embodiments, the insulated heat dissipation end 10 and the first end 210 of the insulated heat dissipation pipe 20 are set to be detachably connected. The above setting facilitates the installation and assemble process of the driving circuit 40 in the insulated heat dissipation pipe 20, and the maintenance of the driving circuit 40. The detachable connection between the insulated heat dissipation end 10 and the first end 210 of the insulated heat dissipation pipe 20 may be a snap connection, a screw connection, or other detachable connection. The connection is not limited in some embodiments.
The insulated heat dissipation pipe 20 provided in some embodiments may be a cylindrical tube, a rectangular tube, a conical tube or a tube of other shapes with a hollow inner space. The shape of the insulated heat dissipation pipe 20 is not limited herein.
The insulated heat dissipation pipe 20 may be made of an insulated heat dissipating material such as ceramic or plastic. The insulated heat dissipation end 10 can also be made of insulated heat dissipating materials such as ceramics and plastics.
Optionally, the insulated heat dissipation pipe 20 in some embodiments may have an elongated shape. The LED lighting module 30 may have a compatible shape. The length of the LED lighting module 30 is basically the same as that of the insulated heat dissipation pipe 20. The LED lighting mode 30 is disposed on the outer wall of the insulated heat dissipation pipe 20 in the length direction of the insulated heat dissipation pipe 20.
Optionally, the insulated heat dissipation tube 20 in some embodiments have an elongated shape. The LED lighting module 30 may include multiple LED strips disposed around the circumferential surface of the insulated heat dissipation pipe 20 in the circumferential direction. Optionally, LED lighting modules 30 can be disposed on the outer wall of the insulated heat dissipation pipe 20 in other forms.
Optionally, in some embodiments, LED lighting modules 30 are disposed on the entire outer wall of the insulated heat dissipation pipe 20. Optionally, LED lighting modules 30 are disposed on part of the outer wall of the insulated heat dissipation pipe 20.
The driving circuit 40 of the present embodiment can be disposed on the inner side of the insulated heat dissipation pipe 20, so that the structure of the LED lamp is more compact. Meanwhile, when the driving circuit 40 is disposed in a larger inner space of the insulated heat dissipation pipe 20, the size limitation of the driving circuit 40 can be reduced. For example, in the insulated heat dissipation pipe 20, the driving circuit 40 can be disposed in the middle of the insulated heat dissipation pipe 20. The drive circuit 40 can also be disposed towards the end of the insulated heat dissipation pipe 20.
Optionally, some part or all parts of the driving circuit 40 can be disposed on the outer side of the insulated heat dissipation pipe 20 so as to facilitate connection with the LED lighting module 30. The setting of the driving circuit 40 can also improve the mounting/assembling speed of the driving circuit 40 on the insulated heat dissipation pipe 20, and improve the production efficiency in mass manufacturing.
As shown in FIG. 1, in order to achieve reliable fixing of the driving circuit 40, a circuit holder 401 is further disposed and the driving circuit 40 is fixedly mounted on the circuit holder 401, so that the stability of the driving circuit 40 can be improved. Accordingly, the problem of voltage instability due to the poor wiring connection caused by the weak fixing of the driving circuit 40 can be effectively prevented. The problem of rapid aging and functional failure of the driving circuit 40 caused by excessive internal resistance of the local lines can be overcome.
The LED lamp provided by the present disclosure has an insulated heat dissipation pipe, an insulated heat dissipation end, and at least one LED lighting module disposed on the outer wall of the insulated heat dissipation pipe. The first end of the insulated heat dissipation pipe has an opening. The insulated heat dissipation end is configured to cover the opening of the first end of the insulated heat dissipation pipe. The insulated heat dissipation end and the second end of the insulated heat dissipation pipe are provided with lamp electrodes. Accordingly, the heat dissipation area of the LED lamp can be increased, and the heat is quickly dissipated to the air through the insulated heat dissipation end and the insulated heat dissipation pipe, thereby improving the heat dissipation speed of the LED lamp. At the same volume, the power and luminous flux outputted by the LED lamp in some embodiments are greater than a traditional LED lamp. Further, the LED lamp in some embodiments has fewer parts and the structure is compact. The assembly steps of the components can be reduced in the assembly and manufacturing process, the production process is simplified, and the production efficiency of the LED lamp is improved.
FIG. 2 illustrates a structural diagram of an exploded view of an LED lamp of Embodiment 2 consistent with the disclosed embodiments. Based on Embodiment 1, as shown in FIG. 2, the LED lamp further includes a lampshade 50 disposed on LED lighting modules 30. A first end of the lampshade 50 is detachably connected to the insulated heat dissipation end 10, and a second end of the lampshade 50 is detachably connected to the second end 220 of the insulated heat dissipation pipe 20.
Specifically, in order to improve the aesthetic appearance of the LED lamp and protect LED lighting modules 30, LED lighting modules 30 are covered with the lampshade 50. Both ends of the lampshade 50 extend to both ends of the insulated heat dissipation pipe 20. As shown in FIG. 2, the first end of the lampshade 50 extends to the insulated heat dissipation end 10, and is detachably connected to the insulated heat dissipation end 10. The second end of the lampshade 50 extends to the second end of the insulated heat dissipation pipe 20, and is detachably connected to the second end 220 of the insulated heat dissipation pipe 20.
The detachable connection of the first end of the lampshade 50 and the insulated heat dissipation end 10, and the detachable connection of the second end of the lampshade 50 and the second end 220 of the insulated heat dissipation pipe 20 may be buckle and slot connections. For example, two buckle structures are disposed on the first end and the second end of the lampshade 50 respectively, and two slot structures having compatible shape with the buckle structures are disposed on the insulated heat dissipation end 10 and the second end 220 of the insulated heat dissipation pipe 20 respectively. During an installation, the slot on the insulated heat dissipation end 10 is aligned with the buckle on the first end of the lampshade 50 and is pressed to fix the first end of the lampshade 50 to the insulated heat dissipation end 10. Similarly, the slot on the second end 220 of the insulated heat dissipation pipe 20 is aligned with the buckle on the second end of the lampshade 50, and is pressed to fix the second end of the lampshade 50 to the second end 220 of the insulated heat dissipation pipe 20. Optionally, two slot structures may be disposed at both ends of the lampshade 50, and two buckle structures may be disposed on the second end 220 of the insulated heat dissipation end 10 and the insulated heat dissipation pipe 20. With the same installation manner described above, the insulated heat dissipation end 10, the second end 220 of the insulated heat dissipation pipe 20 are fixedly connected to the lampshade 50.
In some embodiments, the foregoing setting of buckles and slots on the lampshade 50 is not limited. For example, a slot structure is disposed at the first end of the lampshade 50, and a buckle structure is disposed at the second end of the lampshade 50. Correspondingly, a corresponding buckle and a slot structure on the lampshade 50 are respectively designed on the insulated heat dissipation end 10 and the insulated heat dissipation pipe 20, so that the connections between the lampshade 50 and the insulated heat dissipation end 10 and the second end 220 of the insulated heat dissipation pipe 20 can also be fixed.
Optionally, the specific structures of buckles or slots on the second end 220 of the insulated heat dissipation pipe 20, the lampshade 50, and the insulated heat dissipation end 10 are not limited herein. For example, one or more triangular buckles are disposed at both ends of the lampshade 50. The triangular buckles may be singly distributed at the first end and the second end of the lampshade 50, or the triangular buckles may be distributed at a plurality of even or uneven intervals on the first and second ends of the lampshade 50. Correspondingly, slot structures corresponding to the lampshade 50 are respectively disposed on the second end 220 of the insulated heat dissipation pipe 20 and the insulated heat dissipating end 10. The specific structures and arrangements of buckles and slots can be set as needed.
Optionally, the detachable connection manner of the lampshade 50 and the insulated heat dissipation end 10 and the second end 220 of the insulated heat dissipation pipe 20 may be a threaded connection. For example, an external thread is disposed on the insulated heat dissipation end 10. An internal thread is disposed at the first end of the lampshade 50. The first end of the lampshade 50 is screwed into the insulated heat dissipation end 10. In addition, an external thread is disposed at the second end 220 of the insulated heat dissipation pipe 20, and an internal thread is disposed at the second end of the lampshade 50. The second end 220 of the insulated heat dissipation pipe 20 is screwed into the second end of the lampshade 50.
Optionally, the lampshade 50 in some embodiments is made of a completely transparent material in order to better emit light to the external environment.
Optionally, the lampshade 50 in some embodiments may also be made of a material that is translucent or has a certain transparency, so as to meet the needs of different situations. For example, in some places where darker light is required, a material with low transparency is used to effectively reduce the luminous flux of LED lights to the external environment.
Optionally, a light transmission filter paper having a certain color is disposed on the inner wall or the outer wall of the lampshade 50, so that the primary color light emitted by LED lighting modules 30 can be conveniently filtered to obtain lights of different colors and brightness. The light transmission filter paper is not completely transparent but has certain transparency. For example, the light transmission filter paper having blue light filtering characteristics disposed on the inner wall of the lampshade 50 can effectively remove the blue light ingredient of the light emitted by LED lighting modules 30. By removing the blue light, the eye strain caused by the long-term study, work and life can be reduced. In some embodiments, the filtering color of the light transmission filter paper disposed on the lampshade 50 is not limited. In practical applications, the setting may be selected as needed.
Further, the light transmission filter paper disposed on the lampshade 50 may be placed directly on the entire circumference of the inner wall of the lampshade 50 or may be placed on part of the circumference of the inner wall of the lampshade 50. Optionally, the light transmission filter paper disposed on the lampshade 50 may be placed in part or all of the length direction of the inner wall of the lampshade 50. Through the above setting of the light transmission filter paper, according to actual needs, different selection functions of the light emitted by the LED lamp can be satisfied. For example, the light transmission filter paper is disposed on the 5/6 of the circumference of the lower part of the lampshade 50. A light transmission strip without the light transmission filter paper is left above the lampshade 50, so that the effect of different top and bottom illumination colors or brightness can be satisfied in certain occasions.
Optionally, the lampshade 50 in some embodiments may be a cylindrical tubular structure, or may be a square tubular structure or a polygonal cylindrical structure. The specific structure may be designed according to actual needs.
As shown in FIG. 2, when the lampshade 50 is a cylindrical tube, the lampshade 50 not only covers the LED lighting module 30, but also covers the outer wall of the entire insulated heat dissipation pipe 20.
FIG. 3 illustrates another structural diagram of an exploded view of the LED lamp of Embodiment 2 consistent with the disclosed embodiments. In a possible implementation, as shown in FIG. 3, LED lighting modules 30 in some embodiments may be disposed on a first part of the outer wall of the insulated heat dissipation pipe 20. The other part, i.e., a second part, of the outer wall of the insulated heat dissipation pipe 20 that is not provided with LED lighting modules may be exposed to the exterior of the LED lamp. The lampshade 50 may only cover the part of the outer wall disposed with LED lighting modules. The lampshade 50 together with the second part of the outer wall without any LED lighting module may form the outer circumferential surface of the LED lamp. In some embodiments, the lampshade 50 and the second part of the outer wall of the insulated heat dissipation pipe 20 have a same length and together form a cylindrical tube. For example, the lampshade 50 may occupy 270 degrees of the circumferential wall of the cylindrical tube, and the second part of the outer wall of the insulated heat dissipation pipe 20 may occupy the remaining 90 degrees of the circumferential wall of the cylindrical tube. The lampshade 50 and the second part of the outer wall of the insulated heat dissipation pipe 20 may have compatible shape at their respective connecting edges. For example, during installation, the lampshade 50 may slide onto the second part of the outer wall of the insulated heat dissipation pipe 20 to form the cylindrical tube. The diameter of the first part of the outer wall of the insulated heat dissipation pipe 20 may be smaller than the second part of the outer wall of the insulated heat dissipation pipe 20 to leave room for the LED lighting modules 30 to be attached thereon. For example, LED lighting modules 30 are not disposed on the top section of the insulated heat dissipation pipe 20. When the lampshade 50 is disposed on the outer side of the insulated heat dissipation pipe 20, the top section of the insulated heat dissipation pipe 20 with no LED lighting modules 30 attached thereon is also designed to be open (i.e., exposed to an exterior of the LED lamp and forms a part of the outer shell of the LED lamp) without being covered by the lampshade. Accordingly, when LED lighting modules 30 emit light to generate heat, heat can be directly dissipated to the ambient environment through the open channel at the top while heat is dissipated through the insulated heat dissipation pipe 20, thereby accelerating heat dissipation of LED lighting modules 30, and improving the stability and the life of the LED lamp.
The LED lamp provided by some embodiment of the present disclosure realizes the protection of LED lighting modules by disposing a lampshade covering LED lighting modules. In addition, the LED lamp emits lights of different colors by setting the color of the lampshade.
FIG. 4 illustrates a structural diagram of an exploded view of an LED lamp of Embodiment 3 consistent with the disclosed embodiments. As shown in FIG. 4, in order to improve the mounting reliability of LED lighting modules 30 on the insulated heat dissipation pipe 20, at least one groove 240 is disposed on the outer wall of the insulated heat dissipation pipe 20, and LED lighting module 30 are disposed in the groove 240. In other words, the outer wall of the insulated heat dissipation pipe 20 may include one or more grooves configured to host the LED lighting module 30.
The number of grooves 240 may be the same as the number of LED lighting modules 30. That is, one LED lighting module 30 (e.g., one substrate attached with one or more LED chips) is disposed in one of the grooves 240. Or the number of grooves 240 is greater than the number of LED lighting modules 30. When LED lighting modules 30 are disposed in grooves 240, there are redundant grooves 240 for subsequent use in supplementing LED lighting modules 30.
Optionally, grooves 240 in some embodiments may be distributed in the circumferential direction of the insulated heat dissipation pipe 20. Specifically, grooves 240 are disposed on part of the circumferential surface of the outer wall of the insulated heat dissipation pipe 20 such as front 1/3 of the circumferential surface of the insulated heat dissipation pipe 20. When LED lighting modules 30 are disposed in grooves 240, LED lighting modules 30 are also distributed in the circumferential direction of the insulated heat dissipation pipe 20.
Optionally, grooves 240 in some embodiments may be distributed along the length direction of the insulated heat dissipation pipe 20. When LED lighting modules 30 are disposed in grooves 240, LED lighting modules 30 are also distributed in the length direction of the insulated heat dissipation pipe 20.
In some embodiments, by disposing a plurality of grooves 240 on the insulated heat dissipation pipe 20, LED lighting modules 30 are disposed in grooves 240, thereby facilitating positioning and mounting of LED lighting modules 30, and improving the structural stability, the in-use reliability and service life of LED lamps.
Optionally, the upper surfaces of LED lighting modules 30 and an outer surface of the outer wall of the insulated heat dissipation pipe 20 can be located on the same arc surface, so that the LED lighting module 30 and the insulated heat dissipation pipe 20 are more closely matched, and the structural reliability of the LED lamp is improved.
Optionally, as shown in FIG. 1, FIG. 2 and FIG. 4, LED lighting modules 30 in some embodiments are disposed on the entire outer wall of the insulated heat dissipation pipe 20, thereby improving the illumination amount of the LED lamp.
Optionally, LED lighting modules 30 in some embodiments may be disposed on the outer wall of the insulated heat dissipation tube 20 at certain intervals according to specific needs. For example, LED lighting modules 30 are disposed at equal intervals, so that lights emitted by the LED lamps are more uniform.
In a possible implementation, LED lighting modules 30 are disposed in the length direction of the insulated heat dissipation pipe 20, and the groove 240 extends toward both ends of the insulated heat dissipation pipe 20.
Specifically, as shown in FIG. 4, since LED lighting modules 30 are disposed in the length direction of the insulated heat dissipation pipe 20, grooves 240 are also disposed in the length direction of the insulated heat dissipation pipe 20 accordingly. Specifically, two ends of grooves 240 extend toward both ends of the insulated heat dissipation pipe 20.
Optionally, grooves 240 can be directly connected to both ends of the insulated heat dissipation pipe 20, that is, grooves 240 are through grooves connecting the two ends of the insulated heat dissipation pipe 20. The setting of through groove can simplify the machining of the insulated heat dissipation pipe 20, and be beneficial to the mass production.
Optionally, in some embodiments, notches may be disposed at both ends of grooves 240. Electrodes of LED lighting modules 30 may be connected to the driving circuit 40 through the notch. Optionally, grooves 240 can have through holes at the outer wall of the insulated heat dissipation pipe 20, so that when LED lighting modules 30 are disposed in grooves 240, electrodes of LED lighting modules 30 are directly exposed at a hollow inner space of the insulated heat dissipation pipe 20 (e.g., through a through hole) , and are conveniently connected to the driving circuit 40 in the hollow inner space of the insulated heat dissipation pipe 20.
In some embodiments, the first lamp electrode 101 may be disposed at the center of the insulated heat dissipation end 10. The second lamp electrode 102 is disposed at the center of the second end 220 of the insulated heat dissipation pipe 20.
Optionally, as shown in FIG. 1 to FIG. 4, the first lamp electrode 101 is disposed at an off-center position of the insulated heat dissipation end 10, and the second lamp electrode 102 is disposed at an off-center position of the second end 220 of the insulated heat dissipation pipe 20. The deviation directions of the two lamp electrodes are the same, which facilitates the installation of the LED lamp.
As shown in FIG. 3, when LED lighting modules 30 are disposed on part of the outer wall of the insulated heat dissipation pipe 20, in order to facilitate the installation of the LED lamp, the first lamp electrode 101 is disposed on the insulated heat dissipation end 10 at a position away from the LED lighting module 30. The second lamp electrode 102 is disposed on the second end 220 of the insulated heat dissipation pipe 20 at a position away from the LED lighting module 30.
FIG. 5 is a front view of the first lamp electrode and the first insulated heat dissipation end of Embodiment 3 consistent with the disclosed embodiments. As shown in FIG. 5, the insulated heat dissipation end 10 and the first lamp electrode 101 are taken as an example. The positional relationship between the second end 220 of the insulated heat dissipation pipe 20 and the second lamp electrode 102 is the same as the positional relationship between the insulated heat dissipation end 10 and the first lamp electrode 101. When the projection connection of the LED lighting module 30 on the plane of the insulated heat dissipation end 10 is located on the negative half-axis of the Y-axis, the first lamp electrode may be disposed on the positive half-axis of the Y axis in some embodiments. Accordingly, in actual installations, the distance between the first lamp electrode 101 and the mounting seat of the LED lamp is reduced, thereby facilitating the installation and reducing the installation space of the LED lamp.
In a possible implementation, in order to enrich the functions of the LED lamp, the LED lamp in some embodiments includes a control module (not shown in figures) and a functional module (not shown in figures) . The control module is connected to the functional module and the drive circuit 40 respectively. The functional module may be a voice module, a wireless communication module, or the like.
For example, in the case where the switch is inconvenient to use, the opening and closing of the LED lamp can be controlled by the voice module. In the voice module the command phrases are preset, such as "light on" , "light off" , "increase the brightness" , "decrease the brightness" , "warm light" , "cold light" , "normal light" , "timed light off" , "1 hour" , "2 hour" , "timed light on" , "timed cancellation" and the like. When a user issues the above commands or the combinations of the above commands, the voice module can communicate the commands to the control module. According to the commands, the control module controls the driving circuit 40 to trigger the LED lighting module 30 to perform corresponding opening and closing, brightness adjustment, chrominance adjustment or the like. For example, when a user issues a "light on" command, the voice module receives the voice command "light on" issued by the user. The voice "light on" is parsed into a binary coded command through a decoder in the voice module. The voice module communicates the binary code command to the control module, and controls the drive circuit 40 to close the circuit to turn on the LED lamp. It should be noted that, the naming of the specific commands of the voice commands, the language used by the specific commands of the voice commands, the method of speech decoding and the decoding code system are not limited herein.
Optionally, in some embodiments, the terminal device can remotely control the LED lamp through the wireless connection module. For example, through a mobile phone client, a wireless remote controller, a computer client and the like, any existing wireless communication method such as Bluetooth, WIFI, or the like is connected to the LED lamp to control the opening and closing of the LED lamp, and control the brightness, chromaticity, timing switch, real-time status monitoring, and the like of the LED lamp.
In some embodiments, by setting a plurality of grooves on the insulated heat dissipation pipe, the LED lamp disposes LED lighting modules in the grooves, thereby facilitating positioning and mounting of the LED lighting module, and improving the structural stability of the LED lamp and the in-use reliability and service life of the LED lamp. Further, by setting a functional module in the LED lamp, the functions of the LED lamp are enriched, and the market competitiveness of the LED lamp is enhanced.
