[0002] Portable ED lamps are small in size, simple in structure, and can be powered by dry batteries, making them highly cost-effective and popular in the market. Portable LED lamps typically include a battery compartment with a mounting bracket for batteries. One end of the battery compartment is connected to the lamp head via a connector, and a switch holder is also provided to control the on / off switch of the lamp head. The lamp head is equipped with multiple LED lamp beads, and the other end of the battery compartment is sealed by a base. Typically, multiple dry batteries or a longer 18650 battery are required during use. In the specific circuit, a constant current circuit (such as Figure 1 As shown, by adding a constant current source circuit consisting of two NPN transistors and two resistors, a universal power supply for three AA batteries (4.5V) and a single 18650 battery (3.7V) is achieved, making the current stable when powered by both batteries. More specifically, R2 is an adjustment resistor, and the voltage across R2 is 0.7V, which is not affected by the power supply VCC. This achieves a constant total current flowing through the nine LED lamp beads (D1-D9) between 3.7V and 4.5V. The total current flowing through the nine LEDs is I = 0.7 / R2). The installation of a mounting bracket can make the battery more stable in the battery compartment. Specifically, in the prior art, the mounting bracket is generally fixed to the switch base by welding. After the battery is installed, it is sealed by the base, so that the battery can normally achieve its power supply function. However, in actual use, the battery needs to be replaced after it is exhausted. The battery will cause a certain impact on the mounting frame during the installation process. If the frequency of battery replacement increases, the connection between the mounting frame and the switch seat may cause desoldering due to repeated impact, resulting in a high failure rate.

[0033] In an exemplary embodiment, Figure 1-5 As shown, this embodiment provides a portable LED lamp, which includes a battery 1 and a silo 2. A mounting bracket 3 for installing the battery 1 is provided in the silo 2. A first connecting seat 4 and a second connecting seat 5 are detachably provided at both ends of the silo 2. The first connecting seat 4 is also connected to a lamp head 6. The lamp head 6 is provided with 9 LED lamp beads 7. A switch seat 8 is also installed on the silo 2. One end of the mounting bracket 3 is elastically abutted against the switch seat 8, and the other end is abutted against the second connecting seat 5. The switch seat 8 is provided with a button 9 protruding from the outside of the silo 2, thereby controlling the opening and closing of the switch seat 8 to realize the power on and off of the lamp head 6.

[0034] like Figure 1-5As shown, more specifically, in this solution, the mounting bracket 3 for installing the battery 1 can be directly taken out, and after the battery 1 is installed, it is placed together in the silo 2, and then closed by the second connecting seat 5. After closing, the mounting bracket 3 is electrically connected to the switch seat 8 by elastic abutment. The mounting bracket 3 and the switch seat 8 are elastically abutted, and there is no problem of desoldering, which avoids the problem of failure caused by repeated impact, and solves the problem of high failure rate caused by desoldering at the welding point between the mounting bracket 3 and the switch seat 8 in the prior art; at the same time, the mounting bracket 3 in this solution can be used for multiple dry batteries 1, or for one 18650 battery 1. It also uses a constant current circuit, which has better adaptability. When multiple dry batteries 1 are installed, the number of impacts of the battery 1 on the switch seat 8 can also be reduced.

[0035] like Figure 3-5 As shown in more detail, the mounting bracket 3 and the switch seat 8 can be abutted by a spring piece 10 of a U-shaped structure. The spring piece 10 includes an integrally formed first transverse plate 11, a bent plate 12 and a second transverse plate 13. The free end of the first transverse plate 11 is bent outward of the U-shaped structure and fixed to the switch seat 8. The second transverse plate 13 is longer than the first transverse plate 11 and initially the free end of the second transverse plate 13 is inclined in a direction away from the first transverse plate 11. The first transverse plate 11, the bent plate 12 and the second transverse plate 13 are integrated metal plates. The bent plate 12 has a certain compressive deformation function. When the mounting bracket 3 is installed, it first abuts against (or is close to) the second transverse plate 13, and then when it is squeezed when the second connecting seat 5 is connected, the second transverse plate 13 transmits pressure to make the bent plate 12 bend, thereby making the mounting bracket 3 The frame 3 is elastically pressed against the spring 10. After the battery 1 is installed, its positive pole is pressed against the end of the mounting frame 3. The end of the mounting frame 3 is made of metal, which indirectly realizes the electrical connection with the spring 10. The middle section of the mounting frame 3 is made of non-metallic material and plays the role of fixing the battery 1. At the same time, it prevents the negative pole of the battery 1 from being directly electrically connected to the positive pole through the mounting frame 3. A conductive spring 14 is fixedly connected to the second connecting seat 5 and can be pushed into the mounting frame 3 and pressed against the negative pole of the battery 1. Specifically, the conductive spring 14 can be a variable diameter spring with one end large and the other end small. The large end is connected to the second connecting seat 5, and the small end can be conveniently entered into the mounting frame 3 through a through hole set at the end of the mounting frame 3 for the battery 1 to be placed, and elastically pressed against the negative pole of the battery 1, thereby realizing the power supply of the battery 1.

[0036] like Figure 2-5As shown, the portable LED lamp provided by this solution can be easily fixed. Specifically, a magnet block 15 is provided on the second connecting base 5. The magnet block 15 can be strongly magnetic. The second connecting base 5 is fixed on an iron basis by adsorption, such as an iron bed, or adsorbed on an iron part of a car during car maintenance, so as to be convenient for use in different lighting environments. In more detail, the magnet block 15 can be annular and fixed on the end face of the second connecting base 5 by interlocking.

[0037] like Figure 2-12 As shown, in another embodiment of the present scheme, a connecting hole 16 is provided on the second connecting base 5, and different types of fixing clips can be connected through the connecting hole 16. The fixing clip is connected to the second connecting base 5 through a connecting rod 17, and the portable LED lamp is conveniently fixed by means of the fixing clip; in more detail, the connecting hole 16 can be a threaded hole, and the connecting rod 17 can be a screw rod, which makes it convenient to disassemble the fixing clip, replace different fixing clips, or choose to use magnetic fixation or fixing by a fixing clip; in further detail, the set magnet block 15 can be concentrically surrounded by the outside of the connecting hole 16, so that the magnet block 15 can also play a role in assisting the connection of the connecting rod 17, so that the fixation of the fixing clip is more stable.

[0038] like Figure 2 、 6 As shown in Figure 7, in a more detailed solution, the fixing clamp includes a first half ring 18 and a second half ring 19 opposite to each other, and the two ends of the first half ring 18 and the second half ring 19 are connected by a first locking rod 20. The connecting rod 17 is connected to the first half ring 18, and the two first locking rods 20 can be connected by a threaded connection. In this way, during installation, the first half ring 18 can be placed on a mounting base, such as a cross bar, and then the second half ring 19 can be connected and locked, or the first half ring 18 and the second half ring 19 can be connected first, so that the mounting base passes between them and then locked.

[0039] like Figure 2 、 8 As shown in Figure 9, in another more detailed scheme, the fixing clamp includes a third half ring 21 and a fourth half ring 22 opposite to each other, one end of the third half ring 21 and the fourth half ring 22 are rotatably connected, and the other end is connected by a second locking rod 23, so that one end of the third half ring 21 and the fourth half ring 22 can be pulled apart, and then they can be conveniently put on the installation foundation, such as a cross bar, and then locked by the second locking rod 23. The second locking rod 23 can also be locked by a threaded connection.

[0040] like Figure 2 、 10-12, in another more detailed solution, the fixing clamp includes a mounting block 24, and a fifth half ring 25 and a sixth half ring 26 which are respectively rotatably connected to and opposite to the mounting block 24, and a tensioning rod 27; a first tensioning hole 28 and a second tensioning hole 29 are respectively provided on one end of the fifth half ring 25 and the sixth half ring 26 which are rotatably connected to the mounting block 24, the tensioning rod 27 passes through the first tensioning hole 28 and the second tensioning hole 29, and a tensioning spring 30 is provided around the outer ring of the tensioning rod 27 and is located between the fifth half ring 25 and the sixth half ring 26, one end of the tensioning rod 27 is fixedly connected to a limiting ring 31 which can be inserted into the first tensioning hole 28 or the second tensioning hole 29, and the other end is threadedly connected to a tensioning cap 31 which can be inserted into the second tensioning hole 29 or the first tensioning hole 28 2. In this way, the fifth half ring 25 and the sixth half ring 26 can be opened or closed between the ends facing away from the mounting block 24, so that they can be put on the mounting base, such as a cross bar, and then the tensioning rod 27 can be pulled and closed by rotating the tightening cap 32. The tightening spring 30 provided therein can assist the fifth half ring 25 and the sixth half ring 26 to move away from each other during disassembly; in a more detailed scheme, the first tightening hole 28 and the second tightening hole 29 are both T-shaped in cross section, and the limit ring 31 and the tightening cap 32 cannot pass through. At the same time, a strip hole 33 is provided at the end close to the first tightening hole 28 and the second tightening hole 29 to allow the tensioning rod 27 to be laterally displaced during the rotation of the fifth half ring 25 and the sixth half ring 26 to avoid jamming.

[0041] like Figure 6-12 As shown, in this solution, elastic buffer pads, such as rubber pads, can be directly added between the first half ring 18 and the second half ring 19, between the third half ring 21 and the fourth half ring 22, and between the fifth half ring 25 and the sixth half ring 26 to increase the stability during clamping and prevent them from direct contact with the installation base and causing wear and damage to each other.

[0042] like Figure 2-12As shown, further, the portable LED lamp also includes a bellows 34, and the first connecting seat 4 is also connected to a first connecting head 35. One end of the bellows 34 is rotatably connected to the first connecting head 35, and the other end is rotatably connected to the second connecting head 36. The lamp head 6 is installed on the second connecting head 36. The bellows 34 can be plastic or metal, which makes it convenient for the lamp head 6 to rotate to adjust the lighting angle; more specifically, in this solution, the first connecting seat 4, the second connecting seat 5 and the silo 2 can be threadedly connected, and the first connecting head 35 and the first connecting seat 4, as well as the second connecting head 36 and the lamp head 6 can also be threadedly connected. The bellows 34 is used for wires to pass through, so that the power supply (i.e., the battery 1 in the mounting bracket 3) can smoothly power the lamp head 6. A sealing ring 38 can be added at each threaded connection, and the button 9 is also protected by a button waterproof cap 37. In this way, the portable LED lamp has better waterproof performance and can be better used in outdoor environments.

[0043] like Figure 3 、 4 As shown, a circuit board 39 is also installed between the switch seat 8 and the first connecting seat 4, and the electrical connection between the switch seat 8 and the circuit board 39 is also achieved through the spring 10, which can also avoid the occurrence of desoldering; in more detail, a sealing insulating rubber pad 40 is also provided in the first connecting seat 4 and buckled on the circuit board 39 to maintain the stability of the circuit board 39. At the same time, a hole is provided on the top of the sealing insulating rubber pad 40 for the wire to pass through smoothly, so as to realize the electrical connection between the circuit board 39 and the lamp holder 6.
