Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, Fig. 1 is an LED lighting fixture 100 provided by a preferred embodiment of the present invention, which includes a lamp tube 11, two lamp caps 12 sleeved at both ends of the lamp tube 11, and a light source housed in the lamp tube 11 The assembly 13 and two driving power sources 14 accommodated in the lamp holder 12 and connected to the lamp holder 12 and the light source assembly 13 .

The following will specifically describe the components of the LED lighting fixture 100 according to the embodiment of the present invention and their connection relationship with each other.

Please refer to FIG. 3 and FIG. 4 , the lamp tube 11 is in the shape of a round tube and can be made of polycarbonate (Polycarbonate, PC) material. The lamp tube 11 is provided with a receiving space 110 for receiving the light source assembly 13 . The inner wall of the lamp 11 is provided with two opposite limiting portions 111 bent at right angles. Each limiting portion 111 includes a vertical portion extending vertically and a horizontal portion extending from the vertical portion to the inside of the receiving space 110 . The two limiting parts 111 can limit the movement of the light source assembly 13 in the up and down direction. A receiving channel 112 is formed between the limiting portion 111 and the inner wall of the lamp tube 11 . In addition, the lamp tube 11 is further provided with a pair of clamping holes 113 located above the limiting portion 111 and symmetrically distributed along the radial direction of the lamp tube 11 . The clamping holes 113 are square in shape.

Please refer to FIG. 5 in combination with FIG. 7. The lamp holder 12 is in the shape of a cylindrical shell and is made of engineering plastics. Specifically, materials such as nylon, polycarbonate, and ABS can be selected. The lamp holder 12 includes an insulating cover 120 and a copper needle 121 disposed on the insulating cover 120 , and the insulating cover 120 and the copper needle 121 can be combined by assembly or embedded molding. The insulating cover 120 is sheathed on both sides of the lamp tube 11 . Each insulating cover 120 is provided with a positioning portion 122 that can be accommodated in the receiving channel 112 of the lamp tube 11 and a pair of locking portions 123 matched with the locking holes 113 .

When the two lamp caps 12 are sleeved on both sides of the lamp tube 11 , each positioning portion 122 is accommodated in the receiving channel 112 so that the lamp caps 12 cannot rotate and move relative to the lamp tube 1 in the circumferential direction. In addition, the positioning portions 122 of the two lamp caps 12 respectively abut against the two sides of the light source assembly 13 to realize the positioning of the light source assembly 13 in the axial direction.

The end hook portion of the clamping portion 123 is clamped in the clamping hole 113 , and the fixed connection is realized through the buckling fit between the lamp cap 12 and the lamp tube 11 . Since the clamping portion 123 on the lamp base 12 and the clamping hole 113 on the lamp tube 11 have a simple structure, and the cooperation between the two is simple and easy, the lamp base 12 and the lamp tube 11 can be quickly connected.

Referring to FIG. 2 to FIG. 4 in conjunction with FIG. 7 , the light source assembly 13 includes a substrate 130 , a plurality of LED light emitting units (not shown) disposed on the substrate 130 , and a socket connector 132 assembled on the substrate 130 . The light source assembly 13 is positioned in the lamp tube 11 by glue. It should be further explained that the positioning portions 122 of the two lamp caps 12 respectively abut against the two ends of the substrate 130 of the light source assembly 13 to further position the light source assembly 13 in the axial direction.

Several LED light emitting units are arranged in a straight line on the substrate 130 , but the arrangement is not limited thereto. For example, the LED light emitting units can also be arranged in multiple rows or in an S shape. The LED light emitting unit may be in the form of a packaged chip or a die, and is mounted on the substrate 130 through a surface mount technology (Surface Mount Technology, SMT).

The socket connector 132 is disposed on a side end of the substrate 130 , and the socket connector 132 can also be installed on the substrate 130 by SMT. The receptacle connector 132 includes an insulating body (not shown) having a receiving cavity (not shown) and a plurality of conductive terminals (not shown) installed in the insulating body.

In the embodiment of the present utility model, the driving power supply 14 refers to an electronic control device connected between an alternating current (AC) or direct current (DC) power supply outside the lighting device and the light-emitting diode as a light source, and is used to provide the light-emitting diode with the required current or voltage (such as constant current, constant voltage or constant power, etc.). Please refer to the figure, the driving power supply 14 includes a printed circuit board 141 and one or more components mounted on the printed circuit board and electrically connected together through wiring. Examples of these components include but are not limited to LED driver controller chips, rectifier Chips, resistors, capacitors and coils, etc. The electrical connection between the driving power source 14 and the copper pin 121 of the lamp cap 12 can be realized through a wire (not shown), such as a single-core hard wire.

What needs to be emphasized here is that the printed circuit board 141 is provided with a plug portion 142 mated with the socket connector 132 on the light source assembly 13 , and the plug portion 142 is a golden finger structure. When the driving power supply 14 is assembled with the light source assembly 13, the plug portion 142 of the printed circuit board 141 of the driving power supply 14 is directly inserted into the socket connector 132 of the light source assembly 13, thereby realizing the electrical connection between the driving power supply 14 and the light source assembly 13. . The plugging fit between the plug part 142 and the socket connector 132 makes the connection between the driving power source 14 and the light source assembly 13 convenient and fast. In addition, due to the insertion and extraction force between the socket connector 132 and the plug portion 142 , a fixed connection between the driving power source 14 and the light source assembly 13 is also achieved.
