Description

Technical Field

[0001] The utility model relates to the technical field of LED pixel light strips, and in particular to an LED pixel light strip. Background Art

[0002] LED pixel light strips are also called pixel light strips. In actual engineering applications, several pixel light strips are usually arranged and combined in sequence according to a predetermined design scheme (such as decorative lighting graphics, building outlines, etc.) to assemble into a complete lighting decoration or display system.

[0003] When using existing LED pixel light strips, the wires in the strips are used to connect the individual LED lamp beads and connect the strip to the power supply. When current flows through the wires, due to the wire's resistance, according to Joule's law, the current flowing in the wires generates heat. This heat generation is particularly noticeable when the wires are thin, long, or the current is high. As the current flows through the light strip, heat is generated on the outer surface of the light strip. If this heat is not dissipated in a timely manner, it will affect the use of the light strip in the long term and will cause greater losses in the light strip. Therefore, an LED pixel light strip is proposed. By dissipating heat from the lamp beads and wires separately, the heat dissipation efficiency of the LED pixel light strip is improved, thereby solving the above problems. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes an LED pixel light bar to more accurately solve the above-mentioned problem that when current passes through the wire, due to the presence of a certain resistance in the wire, according to Joule's law, the current flowing in the wire will generate heat, especially when the wire is thinner, longer or the current is larger, the heat generated by the wire will be more obvious. Due to the current passing through the inside of the light bar, heat will be generated on the outer surface of the light bar. If the heat is not dissipated in time, it will affect the use of the light bar for a long time, and the loss on the light bar will be greater.

[0005] The utility model is achieved through the following technical solutions:

[0006] The utility model proposes an LED pixel light bar, comprising a lamp housing, wires and lamp beads, and is characterized in that: an outer shell is connected to the upper side of the lamp housing through a slot, a row of equally spaced limiting holes are provided on the outer shell, a heat dissipation shell is fixedly installed in the limiting holes, a heat dissipation shell is fixedly installed below the heat dissipation shell, a heat-conducting silicon plate is fixedly installed below the heat dissipation shell, a heat-conducting copper plate is provided below the heat-conducting silicon plate, heat dissipating fins are fixedly installed between the heat-conducting silicon plate and the heat dissipating fins, the lamp beads are equally spaced below the heat-conducting copper plate, a protective plate is provided on each side of the outer shell, and the wires are located between the heat dissipation fins and the protective plate on both sides of the outer shell.

[0007] Furthermore, the upper portion of the heat dissipation shell is hemispherical, and radial heat dissipation holes are opened on the heat dissipation shell.

[0008] Furthermore, the heat dissipation holes are circular through holes, and a spacing is provided between each heat dissipation shell.

[0009] Furthermore, a ventilation opening that is wide on the outside and narrow on the inside is provided in the protective plate, and the narrow opening is formed on the side of the protective plate close to the shell.

[0010] Furthermore, the thermally conductive silicon plate is located below the limiting hole, and the thermally conductive silicon plate is fixedly connected to the housing.

[0011] Furthermore, the protective plate and the housing are connected by magnets, which facilitates the assembly and use of multiple housings.

[0012] Furthermore, one end of one of the wires on both sides of the housing is connected to the lamp bead and the power supply, and the other wire is connected to the power supply and the switch to form a path.

[0013] Furthermore, when using multiple groups of lamp beads, one end of one of the wires is connected to the lamp beads of this group and connected to the power supply and switch, and the other end is connected in parallel with another group of lamp beads.

[0014] Beneficial effects of the utility model:

[0015] 1. Since the heat dissipation shell is hemispherical and the heat dissipation holes on the heat dissipation shell are radial circular holes, the distance between each heat dissipation shell is appropriate, which does not affect the airflow of the heat dissipation holes on the adjacent heat dissipation shells, thereby facilitating the heat dissipation of a single heat dissipation shell and promoting sufficient auxiliary heat dissipation of the heat dissipation fins, thereby adapting to the assembly and use of multiple groups of lamp beads, and helping to improve the heat dissipation efficiency of multiple groups of lamp beads.

[0016] 2. When the wires on both sides of the shell generate heat, the protective plate is provided with a wide outside and narrow inside vent, which will promote airflow through the wires and heat dissipation fins between the protective plate. The airflow will pass through the protective plate and the wires when it comes into contact with the wires, taking away the heat generated on the wires, thereby facilitating the heat dissipation of the wires and preventing the wires from accumulating heat due to long-term power-on, which may cause aging of the wires.

[0017] 3. When the lamp beads generate heat during operation, the thermal copper plate will absorb and guide the heat generated by the lamp beads. The thermal copper plate will conduct the heat absorbed by the lamp beads to the heat dissipation fins. Since the heat dissipation fins are equidistantly distributed, the heat dissipation area above the thermal copper plate can be increased. When the airflow passes through the protective plates on both sides of the shell, it will contact the heat dissipation fins, thereby taking away the heat absorbed by the heat dissipation fins, thereby dissipating the heat of the heat dissipation fins, thereby promoting the heat dissipation of the lamp beads and preventing the lamp beads from aging due to heat accumulation.

[0026] 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.

[0027] Please refer to Figures 1 to 6 The utility model proposes an LED pixel light bar. During use, wires 13 are fixedly installed on both sides of the shell 10. When the wires 13 are energized, they generate heat due to the resistance of the current passing through them. A row of equally spaced limiting holes 11 are arranged on the shell 10. A heat dissipation shell 20 is fixedly installed in the limiting holes 11. The limiting holes 11 are used to fix the heat dissipation shell 20. A heat-conducting silicon plate 22 is fixedly connected to the bottom of the heat dissipation shell 20. Heat dissipating fins 23 are arranged equally spaced below the heat-conducting silicon plate 22. Heat dissipating copper plates 24 are arranged below the heat dissipating fins 23. The heat dissipating fins 23 are respectively connected to the heat dissipating fins 23. The thermally conductive silicon plate 22 and the thermally conductive copper plate 24 are fixedly connected. The thermally conductive silicon plate 22 and the thermally conductive copper plate 24 are located inside the outer shell 10. When the wires 13 on both sides of the outer shell 10 generate heat, a protective plate 25 is provided on each side of the outer shell 10. A vent with a wide outside and a narrow inside is provided in the protective plate 25, which will promote airflow through the wires 13 and the heat dissipation fins 23 between the protective plate 25. The airflow will pass through the protective plate 25 and the wires 13 when it contacts the wires 13, taking away the heat generated on the wires 13, thereby facilitating the heat dissipation of the wires 13 and preventing the wires 13 from accumulating heat due to long-term power-on, causing aging of the wires 13.

[0028] When the wire 13 is energized, lamp beads 14 are equidistantly distributed under the shell 10. The lamp beads 14 are in contact with the heat-conducting copper plate 24. The lamp beads 14 will generate heat when working. At this time, the heat-conducting copper plate 24 will absorb and guide the heat generated by the lamp beads 14. The heat-conducting copper plate 24 will conduct the heat absorbed by the lamp beads 14 to the heat dissipation fins 23. Since the heat dissipation fins 23 are equidistantly distributed, the heat dissipation area above the heat-conducting copper plate 24 can be increased. When the airflow passes through the protective plates 25 on both sides of the shell 10, it will contact the heat dissipation fins 23, thereby taking away the heat absorbed by the heat dissipation fins 23, thereby dissipating the heat from the heat dissipation fins 23, and then promoting the heat dissipation of the lamp beads 14, and preventing the lamp beads 14 from aging due to heat accumulation.

[0029] When the heat dissipation fins 23 absorb heat, part of the heat will be conducted to the heat dissipation shell 20 through the thermal conductive silicon plate 22. When the airflow passes through the heat dissipation shell 20, the heat on the heat dissipation shell 20 will be taken away. Since the heat dissipation shell 20 begins to have radial heat dissipation holes 21, the heat dissipation holes 21 are circular through holes, which are conducive to increasing the contact area between the heat dissipation shell 20 and the airflow, thereby promoting the heat dissipation of the heat dissipation shell 20 and facilitating auxiliary heat dissipation of the heat dissipation fins 23.

[0030] In this embodiment, a lamp housing 12 is provided below the housing 10 , and two sides of the lamp housing 12 are connected to the bottom of the housing 10 via slots. The housing 10 is used to protect the lamp beads 14 .

[0031] The bottom of the protective plates 25 on both sides of the shell 10 limit the lamp housing 12. The protective plates 25 and the shell 10 are connected by magnets, which can facilitate the assembly and use of multiple shells 10. If it is a single shell 10, the shell 10 and the protective plates 25 can be fixedly connected, making it easy to use.

[0032] The protection plates 25 are located on both sides of the housing 10 and can be used to protect the housing 10 .

[0033] The wires 13 on both sides of the housing 10, one end of one of the wires 13 is connected to the lamp beads 14 and to the power supply, and the other wire 13 is connected to the power supply and the switch to form a pathway. When multiple groups of lamp beads 14 are used, one end of one of the wires 13 is connected to the lamp beads 14 of this group and to the power supply and the switch, and the other end is connected in parallel with another group of lamp beads 14.

[0034] When combining multiple groups of lamp beads 14, it is only necessary to install protective plates 25 on the outer sides of the two outermost shells 10. The airflow will pass through the protective plates 25 through the multiple groups of wires 13 to take away the heat on the wires 13 for heat dissipation, and at the same time take away the heat on the heat dissipation fins 23. Since there are multiple equally distributed heat dissipation fins 23 between the thermally conductive silicon plate 22 and the thermally conductive copper plate 24, when dissipating heat for multiple groups of lamp beads 14, the thermally conductive silicon plate 22 above the heat dissipation fins 23 and the heat dissipation shell 20 will guide the heat on the heat dissipation fins 23 for heat dissipation. Since the heat dissipation shell 20 is hemispherical and the heat dissipation holes 21 on the heat dissipation shell 20 are radial circular holes, the distance between each heat dissipation shell 20 is appropriate and does not affect the airflow circulation of the heat dissipation holes 21 on adjacent heat dissipation shells 20, which is beneficial to the heat dissipation of a single heat dissipation shell 20 and promotes sufficient auxiliary heat dissipation of the heat dissipation fins 23, thereby adapting to the assembly and use of multiple groups of lamp beads 14 and improving the heat dissipation efficiency of multiple groups of lamp beads 14.

[0035] 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.
