[0002] LED lighting is widely adopted due to its energy-saving and long lifespan advantages. LED fluorescent lamps, commonly known as straight tube lamps, typically consist of a tube, a light panel housed within the tube and containing a light source, and lamp holders located at either end of the tube. The lamp holders house a power source, and the light source and power source are electrically connected via the light panel. The light source consists of multiple LEDs arranged on the light panel, with the LEDs arranged along the length of the tube.

[0003] The LED straight tube lamp in the prior art usually includes a lamp tube, a lamp holder, a lamp board, a hollow conductive needle and a power supply, wherein the lamp holder is fixed to the lamp tube, the power supply is arranged in the lamp holder and is electrically connected to the lamp board, the hollow conductive needle is fixed on the end face of the lamp holder and is used to connect to the external lamp holder, and the lamp board is adhesively fixed to the inner circumference of the lamp tube. In order to enable the LED straight tube lamp to adjust the color temperature or brightness of the light, a regulator can be provided on the lamp holder. The regulator is linked to the switch of the power supply to adjust the light output of the LED lamp. However, when adjusting the switch of the power supply, if the power supply module is not fixed inside the lamp holder, the switch will cause the power supply to move together, resulting in problems such as the switch cannot be turned normally or the power supply module is damaged.

[0022] To facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described below. On the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosure of the present invention. The following references to directions such as "axial direction", "above", "below", etc. are intended to more clearly illustrate the structural position relationship and are not limitations on the present invention. In the present invention, the definition of "vertical", "horizontal", and "parallel" is: including situations within ±10% of the standard definition. For example, vertical usually refers to an angle of 90 degrees relative to the reference line, but in the present invention, vertical refers to situations within 80 to 100 degrees.

[0023] As shown in Figures 1 to 3, the present invention provides an LED straight tube lamp lamp base assembly 100 in one embodiment. The LED straight tube lamp lamp base assembly 100 includes: a lamp base 1 and a power supply board 2. The lamp base 1 includes an accommodating space 101, and the power supply board 2 can be disposed in the accommodating space 101 of the lamp base 1. The lamp base 1 also includes an opening 102, and the power supply board 2 can be installed in the lamp base 1 through the opening 102.

[0024] In some embodiments, the power board 2 may further include a first power board 201 and a second power board 202. The first power board 201 and the second power board 202 are arranged parallel or approximately parallel to each other within the accommodating space 101 of the lamp holder 1. The first power board 201 and the second power board 202 can be connected and fixed by a fixing plug 203. Specifically, the first power board 201 and the second power board 202 can be provided with a first plug-in portion 2011 and a second plug-in portion 2021, respectively, and the ends of the fixing plug 203 are respectively inserted into the first plug-in portion 2011 and the second plug-in portion 2021. The first plug-in portion 2011 and the second plug-in portion 2021 can be structures such as grooves or holes.

[0025] In some embodiments, the lamp head assembly 100 may further include a conductive pin 3. The conductive pin 3 is disposed on the lamp head 1 for connecting to an external power source and is electrically connected to the power board 2. Furthermore, the lamp head 1 may include an end portion 103 disposed on a side away from the opening 102. The conductive pin 3 is disposed on the end portion 103. In other words, the lamp head 1 has an end portion 103 on the side closest to the conductive pin 3.

[0026] The lamp base 1 (the main body of the lamp base) can be made entirely of metal, and an insulating device (not shown) can be provided inside the metal lamp base to prevent electrical connection between the metal lamp base 1 and the power source. To achieve insulation, the lamp base 1 (the main body of the lamp base) can also be made of an insulating material, such as plastic. In this embodiment, the main body of the lamp base is made of an insulating material.

[0027] As shown in Figures 1 to 3, the lamp head 1 includes a switch 11, which is at least partially exposed from the lamp head 1 and is disposed on the surface of the lamp head 1. Furthermore, the switch 11 includes an adjustment portion 111 and a connection portion 112. The adjustment portion 111 of the switch 11 is partially exposed from the lamp head 1 and is disposed on the surface of the lamp head 1; the connection portion 112 of the switch 11 is disposed within the interior of the lamp head 1. The first power board 201 includes an adjustment element 21, and the connection portion 112 of the switch 11 can be connected and fixed to the adjustment element 21 on the first power board 201. The lamp head 1 also includes a movable groove portion 12. The adjustment portion 111 of the switch 11 can be disposed within the movable groove portion 12 of the lamp head 1 and can move within the movable groove portion 12. When the adjusting portion 111 moves in the movable groove portion 12, it drives the connecting portion 112 to move. Since the connecting portion 112 is fixedly connected to the adjusting element 21 on the first power board 201, the switch 11 adjusts the adjusting element 21 on the first power board 201 to achieve the effect of adjusting the light output.

[0028] As shown in Figures 4 to 7, the lamp holder 1 includes a power fixing portion 13, which can be arranged inside the lamp holder 1. The first power board 201 is fixed in the power fixing portion 13 of the lamp holder 1. Specifically, the power fixing portion 13 can be a groove-shaped structure, so that the first power board 201 can be inserted into the power fixing portion 13, thereby completing the connection and fixation of the first power board 201 and the lamp holder 1; in other words, the first power board 201 is inserted into the power fixing portion 13, and the first power board 201 and the lamp holder 1 are connected and fixed through the power fixing portion 13. In this embodiment, the power fixing portion 13 is two sets of ribs. The lamp holder 1 has a central axis, and the two sets of ribs of the power fixing portion 13 are respectively arranged on both sides of the central axis of the lamp holder 1. Further, with the connecting line of the conductive needle 3 as the reference line, the two sets of ribs are respectively arranged on both sides of the vertical line perpendicular to the center of the reference line, and the two sets of ribs are symmetrically arranged relative to the vertical line. In other words, the end surface portion 103 includes two conductive pins 3. The lamp holder 1 has a central axis, and a plane including the central axis of the lamp holder 1 bisects the lamp holder 1. The two conductive pins 3 are symmetrical about the plane. The power supply fixing portion 13 comprises two sets of ribs; the two sets of ribs of the power supply fixing portion 13 are symmetrical about the plane. The power supply fixing portion 13 may include a first locking portion 131. The first locking portion 131 may be located on a side away from the opening 102. In other words, the first locking portion 131 may be located on a side closer to the conductive pins 3 than the lamp tube (not shown). The first locking portion 131 may be in the form of a protrusion and located at the end of the power supply fixing portion 13. The first power board 201 may include a second locking portion 22, which is arranged on a side away from the opening portion 102; that is, the second locking portion 22 may be arranged on a side of the first power board 201 away from the lamp tube; in other words, the second locking portion 22 may be arranged on a side of the first power board 201 close to the conductive pin 3; in other words, the second locking portion 22 is arranged on a side closer to the conductive pin 3 than the lamp tube. The second locking portion 22 may be a hole or a recess. When the first power board 201 is inserted into the power fixing portion 13, the end of the first power board 201 may pass through the first locking portion 131 of the power fixing portion 13 due to stress. Afterwards (that is, after assembly), the second locking portion 22 of the first power board 201 may be locked in the first locking portion 131 of the power fixing portion 13. Furthermore, the first locking portion 131 of the power supply fixing portion 13 can be an inclined protrusion, with the height of the first locking portion 131 away from the opening 102 being greater than the height of the first locking portion 22 near the opening 102. Alternatively, the height of the first locking portion 131 near the conductive pin 3 is greater than the height of the first locking portion 131 away from the conductive pin 3. This allows the second locking portion 22 to be easily pushed into the first locking portion 131 and not easily pulled out of it. This allows the first power supply board 201 to be more conveniently and unobstructedly installed in the lamp holder 1, and prevents it from falling out of the lamp holder 1.

[0029] As shown in Figure 8, the end face portion 103 of the lamp holder 1 may include a hole 1031. Viewed perpendicularly to the end face portion 103, the hole 1031 at least partially overlaps with the first locking portion 131. In other words, the hole 1031 may be positioned closer to the first locking portion 131 than elsewhere on the end face portion 103. This allows stress generated by the insertion of the second locking portion 22 into the first locking portion 131 to be relieved through the hole 1031, preventing deformation or cracking of the lamp holder 1 and maintaining its stability.

[0030] In one embodiment, the lamp holder 1 is suitable for an LED straight tube lamp (not shown). The LED straight tube lamp includes a lamp tube, a lamp holder 1 arranged at both ends of the lamp tube, a light source arranged inside the lamp tube, and a power supply. The light source can be a light strip, a soft light board, an FPC board, a filament, etc. The power supply is arranged in the lamp holder 1. In other words, a power supply is provided in the lamp holder 1 (at least a part of the power supply overlaps with the lamp holder 1 in the radial projection of the LED straight tube lamp), and the power supply and the light source are electrically connected through the lamp board. Preferably, the length of the power supply in this embodiment in the direction of extension of the length of the lamp tube is not greater than that of the lamp holder 1. The power supply can be a single unit as a whole (for example, the power supply modules are all concentrated in one component and are arranged in one of the lamp holders 1). Alternatively, the power supply can be divided into two parts, called dual bodies (that is, all the power supply modules are respectively arranged in two components), and the two parts are respectively arranged in the lamp holders 1 at both ends of the lamp tube. In one embodiment, the power supply includes a power supply circuit board carrying a power supply module, and the power supply and the conductive pin 3 are connected by a wire.

[0031] The implementation of the LED lamp cap of the present invention in various embodiments is as described above. It should be noted that in various embodiments, for the same LED lamp, the features including "in the lamp cap design, the lamp cap can be a plastic lamp cap or a full metal lamp cap, and an insulating member is provided inside", "the lamp cap includes a switch", "the switch is at least partially exposed from the lamp cap", "the switch is provided on the surface of the lamp cap", "the switch includes an adjustment portion and a connecting portion", "the adjustment portion of the switch is partially exposed from the lamp cap", "the connecting portion of the switch is provided inside the lamp cap", "the connecting portion of the switch is connected and fixed to the adjustment element on the power board", "the lamp cap includes a movable groove", "the adjustment portion of the switch can be provided in the movable groove of the lamp cap", "the adjustment portion can move in the movable groove", "when the adjustment portion moves in the movable groove, the connection portion is driven to move", etc., can be applied individually or in an integrated manner in practice, so that only one feature is implemented or several features are implemented simultaneously.

[0032] For example, in the lamp cap design, the lamp cap can be a plastic lamp cap or a full metal lamp cap with an insulating component arranged inside.

[0033] For example, the lamp head includes a switch, the switch is at least partially exposed from the lamp head, and the switch is arranged on the surface of the lamp head.

[0034] For example, a switch includes an adjustment portion and a connection portion.

[0035] That is to say, the above features can be arranged and combined in any way and used to improve LED straight tube lamp holders and LED straight tube lamps.
