DETAILED DESCRIPTION

[0023] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0024] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0025] See also Figure 1-Figure 5 In this embodiment, an LED lamp made of aluminum-plastic composite material includes a lamp tube 110 and lamp holders 120 provided at both ends of the lamp tube 110. The lamp tube 110 includes a hollow base 111 and a light-transmitting cover 112 snap-fitted and mounted on the base 111. The base 111 includes an arc-shaped support portion 211 and a horizontal mounting portion 212 provided between the two ends of the arc-shaped support portion 211. A substrate 220 for mounting a light-emitting component is snap-fitted and mounted on the outer wall of the horizontal mounting portion 212. Heat dissipation fins 213 are arranged on the inner wall of the horizontal mounting portion 212 along its length. The lamp holder 120 is snap-fitted and mounted at the corresponding end of the lamp tube 110. A mounting cavity 301 is provided in the lamp holder 120 corresponding to the base 111. A ventilation component 130 for driving air flow in the base 111 is provided in the mounting cavity 301.

[0026] In this embodiment, the light-transmitting cover 112 is mounted on the base 111 by snapping to form a cylindrical lamp tube 110. Thus, the light-transmitting cover 112 is also arc-shaped. The light-transmitting cover 112 is made of PC plastic so that the light emitted by the light-emitting component can pass through the light-transmitting cover 112 for illumination.

[0027] In order to achieve the snap connection of the light-transmitting cover 112 on the base 111, both ends of the light-transmitting cover 112 are bent inward along the length direction to form snap-on portions. External snap-on grooves 214 opening outward are provided at both ends of the horizontal mounting portion 212 along the length direction. The snap-on portions are snapped into the corresponding external snap-on grooves 214, thereby achieving the snap-on installation of the light-transmitting cover 112 on the base 111.

[0028] In this embodiment, in order to achieve the clamping installation of the substrate 220 on the horizontal mounting portion 212, the horizontal mounting portion 212 has inner clamping grooves 215 with inward openings along its length at both ends. The two ends of the substrate 220 extend into the corresponding inner clamping grooves 215, thereby achieving the installation of the substrate 220 on the base 111.

[0029] The substrate 220 is used to mount the light-emitting assembly on the base 111. Specifically, the light-emitting assembly includes a PCB 200 bonded to the center of the substrate 220. LED lamp beads 201 are evenly distributed on the PCB 200. This allows the light-emitting assembly to emit light through the light-transmitting cover 112 for illumination.

[0030] In actual use of this embodiment, the base 111 is made of aluminum, and the substrate 220 is also made of aluminum. The upper surface of the substrate 220 and both sides of the light-emitting component are polished to form a reflective portion. The reflective portion can reflect light reflected from the light-transmitting cover 112 back to the light-transmitting cover 112, thereby improving the light efficiency of the LED lamp. The space between the substrate 220 and the horizontal mounting portion 212 is filled with heat-dissipating silicone. The heat-dissipating silicone can enable the substrate 220 to transfer heat generated by the light-emitting component to the aluminum base 111, and the heat is dissipated through the arc-shaped support portion 211 with a larger surface area, thereby improving the service life of the light-emitting component.

[0031] In this embodiment, the heat dissipation fins 213 are also made of aluminum and are integrally formed on the inner side wall of the horizontal mounting portion 212 so as to be located within the hollow base 111. The heat dissipation fins 213 can further increase the surface area of the base 111, thereby improving the heat dissipation effect of the base 111 and facilitating the service life of the light-emitting assembly.

[0032] Among them, a cavity is provided in the lamp head 120 to facilitate the installation of components of the existing LED lamp (such as a power driver, etc.). In actual use, a partition 300 is provided in the cavity to form an installation cavity 301 in the cavity corresponding to the base 111 and connected to the hollow base 111. Thus, the breathable component 130 is installed in the installation cavity 301, and the breathable component 130 is used to drive the air flow in the base 111, thereby further improving the heat dissipation effect of the base 111.

[0033] In this embodiment, the middle portion of the arc-shaped support portion 211 is provided with air holes 113 evenly distributed along its circumference.

[0034] The ventilation component 130 includes a mounting tube 230 provided on the outer wall of the lamp holder 120 and connected to the mounting cavity 301. A rotatable fan blade 311 is provided in the mounting tube 230 through a bracket 310. The fan blade 311 is used to blow the air in the mounting cavity 301 out of the mounting tube 230. A detachable dustproof component is provided at the opening of the mounting tube 230.

[0035] In actual use of this embodiment, the bracket 310 is installed in the mounting tube 230 by means of a thread. In actual use, the bracket 310 is provided with a micro motor 312 for driving the fan blades 311 to rotate. The micro motor 312 can preferably drive the fan blades 311 to rotate, thereby blowing the air in the mounting cavity 301 out of the mounting tube 230, i.e., generating a negative pressure in the mounting cavity 301, causing the air in the base 111 to flow into the mounting cavity 301, and cooperating with the air intake of the air vent 113, thereby preferably achieving air flow in the base 111;

[0036] The dustproof component is installed at the opening of the mounting tube 230, which can effectively prevent dust from entering the mounting cavity 301 and affecting the use of the LED lamp.

[0037] Specifically, the dustproof assembly includes a dustproof frame 510 threadedly connected to the mounting tube 230 and a dustproof net 511 disposed in the dustproof frame 510 . A handle 512 is provided on the lower side of the dustproof frame 510 along its radial direction.

[0038] The threaded connection of the dustproof frame 510 in the mounting tube 230 can better realize the disassembly and assembly of the dustproof assembly, thereby facilitating the disassembly and assembly of the breathable assembly 130, making the inspection and maintenance of the breathable assembly 130 more convenient.

[0039] The setting of the handle 512 makes it more convenient for the operator to rotate the thread of the dustproof frame 510, which is beneficial to practical use;

[0040] In order to improve the dustproof effect of the lamp tube 110, a dustproof net is also provided at the air hole 113 to prevent dust from entering.

[0041] In this embodiment, in order to better realize the clip-on installation of the lamp holder 120 at the two ends of the lamp tube 110, matching arc grooves 401 are provided on the outer walls of the arc support portion 211 and the light-transmitting cover 112 along their circumference, and a convex ring 501 that can be clipped into the matching arc groove 401 is provided on the inner wall of the lamp holder 120.

[0042] In this embodiment, the convex ring 501 and the arc groove 401 are provided so that the convex ring 501 is engaged with the matching annular arc groove 401 through interference fit, thereby achieving the clamping installation of the lamp holder 120 at both ends of the lamp tube 110.

[0043] In order to enable the installation cavity 301 to correspond to the base 111 when the lamp holder 120 is snap-fitted and installed on the lamp tube 110, in this embodiment, a limiting groove 402 is provided on the outer wall of the light-transmitting cover 112 along its radial direction, and a limiting block 502 that can be snapped into the limiting groove 402 is provided on the inner wall of the lamp holder 120.

[0044] In this embodiment, the position of the lamp holder 120 can be preferably limited by aligning the limiting block 502 with the limiting groove 402, so that when the lamp holder 120 is snap-fitted and mounted on the lamp tube 110, the mounting cavity 301 is kept aligned with the base 111.

[0045] It should be noted that when the lamp holder 120 is installed at the two ends of the lamp tube 110, the partition 300 inside the lamp holder 120 can be close to the corresponding end of the horizontal mounting portion 212, thereby restricting the substrate 220 that is clipped and installed above the horizontal mounting portion 212, so as to prevent the substrate 220 from shaking in the inner slot 215 and affecting the use of the light-emitting component.

[0046] Working principle: When assembling the LED lamp, the two sides of the substrate 220 are aligned and snapped into the inner slot 215, so that the substrate 220 is installed on the base 111, and then the light-emitting component is installed on the substrate 220. At this time, the transparent cover 112 is snap-mounted on the base 111 to form the lamp tube 110, and then the limit block 502 in the lamp head 120 is aligned with the limit slot 402, and the lamp head 120 is snap-mounted at the end of the lamp tube 110 so that the convex ring 501 is snap-mounted in the arc groove 401, thereby completing the snap-mounting installation of the lamp head 120 at both ends of the lamp tube 110. In this way, the assembly of the LED lamp can be completed.

[0047] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
