Because the manufacturing cost of the constant current drive IC chip is lower than that of the power supply required by the traditional light source assembly 22, when the LED support lamps are connected in series, the power supply requirements of a plurality of LED support lamps in series can be met by only arranging one power supply 1 outside the LED support lamps and arranging the constant current drive IC chip 23 in each LED support lamp in series. In addition, the constant current drive IC chip 23 is integrated on the light source assembly 22, and forms an integral device with the light source assembly 22, thereby facilitating mass production. Therefore, the LED bracket lamp provided by the application has a simple series structure and low manufacturing cost.

Fig. 2 is a side sectional view of an LED support lamp according to an embodiment of the present application. As shown in fig. 2, the light source assembly 22 includes a wiring board 220 and an LED element 221, and a constant current drive IC chip 23 is fixed on the wiring board 220;

The circuit board 220 in the light source assembly 22 may be a double-sided flexible circuit board, and the circuit board 220 may implement circuit integration of the first surface 222 and the second surface 223, or alternatively, may be a single-sided flexible circuit board. The LED element 221 may employ LED beads. The plurality of LED elements 221 are uniformly welded on the first surface 222 of the circuit board 220 at preset intervals, and the arrangement manner of the LED elements 221 on the first surface 222 of the circuit board 220 can be customized according to the light emitting principle and design requirements. The constant current drive IC chip 23 may be fixed on the first face 222 of the wiring board 220, alternatively, the constant current drive IC chip 23 may be fixed on the second face 223 of the wiring board 220. An input terminal of the constant current drive IC chip 23 is connected to an output terminal of the input terminal structure 21, and an output terminal of the constant current drive IC chip 23 is connected to the LED element 221.

In this embodiment, the first terminal 213 and the second terminal 214 in the output end of the input end structure 21 are respectively connected to the positive input pin and the negative input pin of the constant current driving IC chip 23, for inputting the dc voltage output from the output end of the power supply 1 into the constant current driving IC chip 23. The output terminal of the constant current drive IC chip 23 is connected to the LED element 221, so that the constant current drive IC chip 23 can output a constant current direct current to supply power to the LED element 221, and the LED element 221 can normally emit light after being energized.

In the above embodiment, the constant current driving IC chip 23 is fixed on the circuit board 220 to meet the power supply requirement of the LED element, and since the constant current driving IC chip 23 can be integrated on the circuit board 220, the constant current driving IC chip 23 and the circuit board 220 form an integral device, and the volume of the constant current driving IC chip 23 is smaller, the problem of material waste caused by the fact that the LED power supply in the conventional LED bracket lamp occupies extra space is overcome. Also, the manufacturing cost of the constant current drive IC chip 23 is low compared with the high manufacturing cost of the power supply required when the LEDs are powered conventionally. Therefore, the method of integrating the constant current driving IC chip 23 on the light source assembly 22 according to the present embodiment saves the space and cost occupied by the LED power supply in the LED support lamp, thereby greatly reducing the manufacturing cost of the LED support lamp. In addition, the current output by the constant current driving IC chip 23 can be set according to the power requirement of the actual LED support lamp, so that when a plurality of LED support lamps need to be connected in series, the series structure of the LED support lamps can meet the power supply requirements of the LED support lamps with different powers.

Alternatively, as shown in fig. 2, the LED element 221 is mounted on the first face 222 of the circuit board 220, and the serial conductor 24 is integrated on the second face 223 of the circuit board 220; the second surface 223 of the circuit board 220 is adhered to the inner wall of the tube body 20 by adhesive.

The material of the serial wire 24 is a conductive material, for example, a copper foil material or an aluminum foil material may be used. The LED support lamp has two series conductors 24, one end of the two series conductors 24 being connected to the output of the input structure 21. The output of the input structure 21 comprises a first terminal 213 and a second terminal 214. The first terminal 213 is connected to one of the series conductors 24, and the second terminal 214 is connected to the other of the series conductors 24. If two series conductors 24 of copper foil material are integrated on the second side 223 of the circuit board 220, two mutually insulated copper foil strips are formed on the second side 223 of the circuit board 220. The width and thickness of the copper foil tape are determined according to the magnitude of the actual energizing current, and the present embodiment is not limited. The second surface 223 of the circuit board 220 is adhered to the central position of the inner wall of the lower end of the pipe body 20 by adhesive, alternatively, the second surface 223 of the circuit board 220 may be adhered to any position of the inner wall of the pipe body 20, and the adhesive specifically adopted may be silicone adhesive. This embodiment is not limited thereto.

In this embodiment, as shown in fig. 2, the first terminal 213 and the second terminal 214 in the output end of the input end structure 21 respectively connect the positive electrode and the negative electrode of the dc voltage output by the output end of the power source 1 to the two serial wires 24 in the tube body assembly 2, so that the serial wires 24 can be normally connected with the power source 1, so that the output end structure 25 of the LED support lamp or the input end structure 21 of another LED support lamp can be conveniently connected with the power source 1. The two series wires 24 are integrated on the second surface 223 of the circuit board 220 to form two mutually insulated conductive paths for connecting the input end structure 21 and the output end structure 25, so that the direct current voltage input by the input end structure 21 can be normally coupled and output to the outside of the LED support lamp through the output end structure 25, and the series connection of at least more than two LED support lamps can be realized. For example, the LED support lamp a is connected in series with the LED support lamp B, the input end structure 21 of the LED support lamp a is connected with the power supply 1, and the direct current voltage output by the output end of the power supply 1 is coupled and input into the LED support lamp a, and the output end structure 25 in the LED support lamp a couples and outputs the direct current voltage output by the output end of the input power supply 1 to the outside of the LED support lamp a through the serial wire 24 in the LED support lamp a. The input end structure 21 of the LED support lamp B is connected with the output end structure 25 of the LED support lamp A, so that the LED support lamp A and the LED support lamp B can be connected in series, and the power can be simultaneously supplied to at least more than two LED support lamps by using one power supply 1.

In this embodiment, the second surface 223 of the circuit board 220 is adhered to the central position of the lower end of the inner wall of the tube body 20 by the adhesive, the position of the adhesive 4 is shown in fig. 2, and as can be seen from fig. 2, the adhesive 4 is fully filled in the gap between the second surface 223 of the circuit board 220 and the inner wall of the tube body 20, so as to tightly fix the circuit board 220 to the inner wall of the tube body 20. The size of the gap can be determined according to the width of the circuit board 220 and the light emitting range of the light source assembly 22 of the LED bracket lamp. In order to increase the light emission range of the light source module 22 of the LED support lamp, for example, the light emission range is 270 °, the light emission range of the light source module 22 of the LED support lamp may be increased by reducing the size of the gap between the circuit board 220 and the inner wall of the tube 20 when the circuit board 220 is firmly bonded to the inner wall of the tube 20 by ensuring that the size of the gap is enough to accommodate the adhesive. It should be noted that, the light emitting range of the light source assembly 22 of the LED bracket lamp may be determined according to practical requirements, so as to determine the size of the gap between the specific circuit board 220 and the inner wall of the tube body 20, which is not limited in this embodiment.

In the above embodiment, the series wires 24 are integrated on the second surface 223 of the circuit board 220 to form two mutually insulated conductive paths, so as to realize the electrical connection between the input end structure 21 and the output end structure 25 in the LED bracket lamp, and since the series wires 24 are integrated on the second surface 223 of the circuit board 220, the series wires 24 and the circuit board 220 form an integral device, thereby overcoming the problems of material waste caused by the redundant space occupied by the arrangement of the series wires 24 outside the tube body 20 in the conventional LED bracket lamp and circuit damage caused by the easy movement of the series wires 24, and the layout method of the series wires 24 provided in the embodiment saves the space occupied by the series wires 24 in the conventional LED bracket lamp, so as to greatly reduce the manufacturing cost of the LED bracket lamp. In addition, the circuit board 220 is directly adhered to the inner wall of the tube body 20 in the embodiment, so that the circuit board 220 and the tube body 20 are integrated, and the LED bracket lamp is not easy to damage the light source assembly 22 due to vibration.

Alternatively, in one embodiment, fig. 3 is a side cross-sectional view of another LED support lamp according to an embodiment of the present application. Fig. 3 relates to another positional relationship of the series conductor 24 and the wiring board 220 in the light source module 22. As shown in fig. 3, a clamping groove 201 is formed on the inner wall of the pipe body 20, and a circuit board 220 is clamped in the clamping groove 201; the LED element 221 is mounted on the first surface 222 of the circuit board 220, and the serial conductor 24 is disposed in a gap formed between the second surface 223 of the circuit board 220 and the inner wall of the tube body 20.

The clamping groove 201 may be fixed on the inner wall of the pipe body 20 in an adhesive manner. The wiring board 220 in the light source assembly 22 may be a hard wiring board, which may be a glass fiber board, alternatively an aluminum substrate. This embodiment is not limited thereto. The plurality of LED elements 221 are uniformly welded on the first surface 222 of the circuit board 220 at preset intervals, and the arrangement manner of the LED elements 221 on the first surface 222 of the circuit board 220 can be customized according to the light emitting principle and design requirements. The material of the serial conductor 24 is a conductive material, for example, a copper foil material or an aluminum foil material may be used. The LED support lamp has two series wires 24, one end of the two series wires 24 is connected to a first output end 213 and a second output end 214 of the output end of the input end structure 21 through wires, respectively, and the other end of the two series wires 24 is connected to the output end structure 25. When two series wires 24 of copper foil material are inserted into the gap formed between the second surface 223 of the circuit board 220 and the inner wall of the tube body 20, the two series wires 24 need to be wrapped with an insulating material to form two conductive paths insulated from each other.

In this embodiment, as shown in fig. 3, the first terminal 213 and the second terminal 214 in the output end of the input end structure 21 respectively connect the positive stage and the negative stage of the dc voltage output from the output end of the power source 1 to the two series wires 24 in the pipe body assembly 2, so that the series wires 24 can be normally connected to the power source 1 for convenient connection between other devices and the power source 1. The two series wires 24 are inserted into a gap formed between the second surface 223 of the circuit board 220 and the inner wall of the tube body 20, so as to form two conductive paths for connecting the input end structure 21 and the output end structure 25, so that the power voltage output by the output end of the power supply 1 input by the input end structure 21 can be output to the outside through normal coupling of the output end structure 25, and the series connection of at least more than two LED bracket lamps can be realized.

In this embodiment, the lower end of the inner wall of the tube body 20 is adhered with a clamping groove 201, the circuit board 220 is clamped in the clamping groove 201, the serial conductor 24 is arranged in a gap between the circuit board 220 and the inner wall of the tube body 20 in a penetrating manner, and the size of the gap can be determined according to the cross-sectional diameter of the serial conductor 24, the width of the circuit board 220 and the light emitting range of the light source assembly 22 of the LED bracket lamp. In order to increase the light emission range of the light source module 22 of the LED support lamp, for example, the light emission range is 270 °, the size of the gap is ensured to accommodate the serial wires 24, and the size of the gap between the circuit board 220 and the inner wall of the tube body 20 is reduced, so that the light emission range of the light source module 22 of the LED support lamp is increased. It should be noted that, the light emitting range of the light source assembly 22 of the LED bracket lamp may be determined according to practical requirements, so as to determine the size of the direct gap between the specific circuit board 220 and the inner wall of the tube body 20, which is not limited in this embodiment.
