Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp tubes, and specifically, to an LED lamp tube with a grooved reflector. Background Technique

[0002] The LED lamp tube is also called an LED fluorescent lamp, and its light source uses an LED as a light-emitting body. The traditional fluorescent lamp tube, also known as a fluorescent lamp, has a filament at each end of the lamp tube. The lamp tube is filled with a small amount of argon and thin mercury vapor, and the inner wall of the lamp tube is coated with fluorescent powder. When the gas between the two filaments conducts electricity, ultraviolet rays are emitted, causing the fluorescent powder to emit visible light. Since it contains the heavy metal pollutant "mercury", the scrapped fluorescent lamp tubes cause serious pollution to the environment. The LED lamp tube uses a light-emitting diode as a light source, with higher light efficiency, more energy-saving, longer service life, and more environmentally friendly.

[0003] For example, an LED lamp tube disclosed in the patent with the publication number CN210291457U can be quickly and adaptively inserted into the slot in the slot part to form a fixation to improve the assembly efficiency. However, in actual use, multiple LED light source boards are often inserted into the slot in sequence. Due to the sequential insertion of the LED light source boards, the LED light source board at the middle position is damaged. When the maintenance personnel perform maintenance on it, they need to take out the LED light source board at its front side from the slot. Therefore, it is inconvenient to maintain the LED light source board of this LED lamp tube, so it needs to be improved. Summary of the Utility Model

Specific embodiments

[0022] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and not for limiting it.

[0023] The following combines the attached Figures 1 - 5 To further illustrate this embodiment in detail.

[0024] As Figures 1 - 2 shown, an LED lamp tube with a grooved reflector in this embodiment includes a lamp tube 110 and lamp holders 100 provided at both ends of the lamp tube 110. The lamp tube 110 includes a lamp base 111 and a lamp shade 112 snap-fitted on the lamp base 111. The lamp base 111 includes a strip-shaped mounting part 201, and a reflector is provided on the mounting part 201. Both sides of the reflector are bent to form a reflecting part 211 and a bottom plate part 212 located in the middle. A plurality of detachable PCB boards 120 are provided on the bottom plate part 212 through a mounting structure, and LED lamp beads 121 are distributed on the PCB boards 120; the lamp holder 100 is snap-fitted and installed at the corresponding end of the lamp tube 110 through a snap-fitting structure.

[0025] In this embodiment, both the lamp base 111 and the lamp shade 112 are arc-shaped. When the lamp shade 112 is snap-fitted on the lamp base 111, a cylindrical lamp tube 110 is formed. Among them, the lamp base 111 further includes an arc-shaped support part, and the support part is arranged along the extension direction of the mounting part 201. A hollow lamp base 111 is formed between the support part and the mounting part 201; among them, the lamp shade 112 is made of a light-transmitting material, such as made of PC material, so that the light emitted by the LED lamp beads 121 can pass through the lamp shade 112 for illumination;

[0026] Among them, in combination with Figure 3 and Figure 4As shown, the reflector is installed on the installation part 201 along the extension direction of the installation part 201. The two sides of the reflector are bent along the extension direction of the installation part 201 to form reflecting parts 211. The reflector located between the reflecting parts 211 forms a bottom plate part 212 that fits the upper side of the installation part 201. Thus, the reflector is configured in a groove shape. Among them, the bottom plate part 212 is used for installing the PCB board 120 and the LED lamp beads 121 on the lamp socket 111. There is a certain inclination angle between the reflecting part 211 and the bottom plate part 212, so that the reflecting part 211 can reflect part of the light emitted by the LED lamp beads 121 to the lampshade 112, thereby improving the light efficiency of the LED lamp tube.

[0027] Specifically, in order to realize the installation of the reflector on the lamp socket 111, in this embodiment, internal buckling grooves 202 are provided on both sides of the installation part 201 along its length direction. The outer sides of the reflecting parts 211 are clamped in the corresponding internal buckling grooves 202. Thus, the installation of the reflector on the lamp socket 111 is realized.

During actual use, heat dissipation silica gel is filled between the bottom plate part 212 and the installation part 201. Thus, the reflector can transfer the heat generated when the PCB board 120 and the LED lamp beads 121 work to the aluminum lamp socket 111, so that the PCB board 120 and the LED lamp beads 121 can be cooled and their service life can be prolonged.

[0029] In this embodiment, multiple PCB boards 120 are sequentially distributed on the installation part 201 along the extension direction of the installation part 201. Among them, through the setting of the installation structure, it can be better disassembled and assembled at any position of the PCB board 120, so that maintenance personnel can repair the damaged PCB board 120 at any position inside the lamp tube 110.

[0030] Among them, the lamp head 100 is clamped and installed at the corresponding end of the lamp tube 110 through a clamping structure, which preferably realizes the disassembly and assembly of the lamp head 100 at the end of the lamp tube 110, that is, it is convenient for the assembly of the LED lamp tube.

[0031] In this embodiment, in order to preferably realize the clamping installation of the lampshade 112 on the lamp socket 111, among them, external buckling grooves 203 located outside the internal buckling grooves 202 are provided on both sides of the installation part 201 along its length direction. The two sides of the lampshade 112 are bent to form clamping parts 221 that are clamped in the external buckling grooves 203.

[0032] Combined with Figure 3 and Figure 4As shown in the figure, in this embodiment, the installation structure includes a fixed clamping member 310 disposed on one side of the bottom plate portion 212 along the length direction of the installation portion 201 and a movable clamping member 320 detachably connected to the other side of the bottom plate portion 212. The movable clamping member 320 includes a plurality of Z-shaped clamping plates 410, and the clamping plates 410 are fixedly installed on the bottom plate portion 212 by screws 420.

[0033] In this embodiment, the fixed clamping member 310 includes an L-shaped plate. One side of the L-shaped plate is integrally formed on the bottom plate portion 212, and the other side is used to press one side of the PCB board 120. Among them, one side of the clamping plate 410 is detachably installed on the bottom plate portion 212 by a screw 420, and the other side is used to press the other side of the PCB board 120. Thus, the installation of the PCB board 120 on the bottom plate portion 212 is preferably realized.

[0034] Among them, a plurality of clamping plates 410 are provided and installed on the bottom plate portion 212 by screws 420. Thus, it is preferably convenient for maintenance personnel to disassemble and assemble the damaged PCB board 120 at any position inside the lamp tube 110 for easy maintenance.

[0035] In this embodiment, a threaded stud 411 for screw 420 to be threadedly connected is provided on one side wall of the clamping plate 410 corresponding to the screw 420.

[0036] In this embodiment, the screw 420 is threadedly connected into the threaded stud 411 to increase the stability of the screw 420 in installing the clamping plate 410.
