[0037] Reference Figure 1 and Figure 2 The indicator light provided in this embodiment includes a light-emitting component 1 and a set of lamp housing components 2, and the lamp housing component 2 sets the light-emitting component 1 inside.

[0038] Reference Figure 3The light-emitting component 1 comprises a light-emitting head 11, a boosting resistor 12, a current-limiting resistor 13 and a step-down component. The light-emitting head 11 comprises an LED chip component 111, which is provided with a first pin 112 and a second pin 113. The boosting resistor 12 has one pin connected to the first pin 112 and another pin connected to the second pin 113. The current-limiting resistor 13 has one pin connected to the first pin 112. The step-down component comprises a capacitor 14 and a discharge resistor 15 arranged in parallel, wherein one pin of the step-down component is connected to the second pin 113, and one pin of the capacitor 14 is wound and connected to one pin of the discharge resistor 15 and then welded.

[0039] In this embodiment of the light-emitting assembly 1, the boost resistor 12 increases the lighting voltage of the light-emitting assembly 1, the current-limiting resistor 13 limits the current when the light-emitting assembly 1 is powered on, and the voltage-stepping assembly reduces the voltage when the light-emitting assembly 1 is powered on. Both the current-limiting resistor 13 and the voltage-stepping assembly protect the light-emitting head 11 from damage caused by excessive current or voltage surges. The discharge resistor 15 eliminates residual charge in the capacitor during power outages, ensuring the safety of the light-emitting assembly 1. Furthermore, by wrapping one pin of the capacitor 14 with one pin of the discharge resistor 15 and then soldering them together, the connection between the voltage-stepping assembly and the light-emitting assembly 1 is more reliable.

[0040] For example, one pin of the discharge resistor 15 can be connected to one pin of the capacitor 14 in a twisted manner and then welded using resistance welding. Alternatively, one pin of the capacitor 14 can be connected to one pin of the discharge resistor 15 in a twisted manner and then welded using resistance welding. In this way, resistance welding eliminates the need for solder, saves welding consumables, and has production cost advantages.

[0041] In a preferred embodiment of the above-mentioned light-emitting component 1, the ends of the first pin 112 and the second pin 113 are both bent, and the pin of the boosting resistor 12 is connected in a twisted manner to a portion before the end of the first pin 112 or the second pin 113. Furthermore, a first bent portion 131 is formed at one end of the pin of the current-limiting resistor 13, and the first bent portion 131 overlaps the end of the first pin 112 and is then soldered. The first pin 112, one pin of the boosting resistor 12, and one end of the pin of the current-limiting resistor 13 can be soldered together.

[0042] In addition, a second bent portion 141 is formed at one end of the step-down component pin, and the second bent portion 141 overlaps the end of the second pin 113 and is then soldered. The second pin 113, one pin of the boost resistor 12, and the connecting portion of one end of the step-down component pin can be soldered together.

[0043] In a preferred embodiment of the light-emitting assembly 1, the light-emitting head 11 further includes an encapsulating shell 16. This encapsulating shell 16 can be made of an epoxy resin material to encapsulate the LED chip assembly 111 therein, thereby protecting the LED chip assembly 111 without affecting the lighting effect. Alternatively, this encapsulating shell 16 can be made of polyurethane, acrylic, phenolic resin, thermoplastic polyurethane, or other materials.

[0044] In a preferred embodiment of the above-mentioned light-emitting assembly 1, the LED chip assembly 111 may include a PCB, multiple rectifier chips, and at least one LED chip connected to the top surface of the PCB. The multiple rectifier chips form a full-bridge rectifier circuit to supply direct current to the LED chip, and the first pin 112 and the second pin 113 extend from the back surface of the PCB. For example, the LED chip assembly 111 may include four rectifier chips and one or more LED chips. The top surface of the PCB is provided with copper-clad circuits and solder pads. All rectifier chips and LED chips are fixed to the solder pads of the PCB through a bonding process. Wirebonds connect the electrodes of all rectifier chips and LED chips to the circuits of the PCB. The pins are fixed to the lead holes of the PCB through riveting and extend from the back surface of the PCB. The four rectifier chips form a full-bridge rectifier circuit to provide direct current in a defined direction to the connected LED chips, thereby eliminating the need for pins to distinguish between positive and negative poles. The multiple LED chips can be connected to the full-bridge rectifier circuit in parallel or series, depending on the operating voltage, to ensure that the LED chips emit light normally.

[0045] In a preferred embodiment of the above-mentioned indicator light, the lamp housing assembly 2 includes a lamp tube 21, a lampshade 22, and a fastening ring 23. The lampshade 22 is threadedly connected to the end. The end of the lamp tube 21 has a larger diameter than the rest of the lamp, and a portion near the end is provided with an externally threaded section. The fastening ring 23 is connected to the externally threaded section to clamp an external mounting plate between it and the end. In this way, the indicator light can be connected to an external device by rotating the fastening ring 23. When the indicator light is operating, the bright light of the light-emitting assembly 1 can be emitted through the lampshade 22.

[0046] In a preferred embodiment of the above-mentioned indicator light, a partition is provided within the lamp tube 21, dividing it longitudinally into two chambers. The chamber near the end houses the light-emitting assembly 1, while the other chamber houses the wiring assembly 3. Furthermore, a pair of threading openings 2122 and a pair of operating holes 2123 are provided at the rear of the lamp tube 21, corresponding to the wiring assembly 3. To connect wires, the wires are threaded through the threading openings 2122 into the wiring assembly 3 and then operated through the operating holes 2123.

[0047] In a preferred embodiment of the above-mentioned indicator light, the wiring assembly 3 includes two wire pressing plates 31, two wire receiving plates 32, and two bolts 33. Each wire pressing plate 31 is provided with a through hole, and each wire receiving plate 32 is provided with a wiring hole for a pin of the light-emitting assembly 1 to pass through at its side end, and a threaded hole is provided in the middle of the wire receiving plate 32. The bolt 33 passes through the through hole and the threaded hole, wherein the bolt 33 corresponds to the operating hole 2123. By operating the bolt 33 in the operating hole 2123, the cable is crimped between the wire pressing plate 31 and the wire receiving plate 32. The wiring hole corresponds to the gap between the wire pressing plate 31 and the wire receiving plate 32.

[0048] In a preferred embodiment of the above-mentioned indicator light, the lamp tube 21 generally includes a body 211 and an end cap 212. The rear end of the body 211 is open, and two sockets 2111 are provided on the side walls of the rear end. A snap-fitting recess is provided on each of the two opposing side walls of the sockets 2111. Two inserting plates 2121 are formed on the side walls of the end cap 212. Each inserting plate 2121 is provided with a snap-fitting protrusion that mates with the snap-fitting recess, allowing the end cap 212 to snap onto the rear end of the body 211. Furthermore, a threading hole is provided between the inserting plates 2121 and the sockets 2111, and an operating hole 2123 may be formed on the end cap 212.

[0049] The present application relates to the field of low-voltage electrical components, and in particular to a light-emitting component 1 and an indicator light. The lamp housing component 2 of the indicator light sets the light-emitting component 1 therein. In the light-emitting component 1, the boost resistor 12 serves to increase the lighting voltage of the light-emitting component 1, and the current-limiting resistor 13 and the step-down component both serve to protect the light-emitting head 11 from being damaged by excessive current or voltage shock. Among them, the discharge resistor 15 can also ensure the safety of the light-emitting component 1. In addition, by winding and connecting one pin of the capacitor device 14 with one pin of the discharge resistor 15 and then welding them, the connection between the step-down component and the light-emitting component 1 is made more reliable. In this way, the quality of the light-emitting component 1 and the indicator light can be improved.
