Description

Technical Field

[0001] This utility model relates to the field of fishing gear technology, specifically to an infrared supplementary lighting float. Background Technology

[0002] In fishing, the float is a crucial tool for monitoring fish bites, and its sensitivity and visibility directly affect the fishing results. Existing illuminated floats generally suffer from the following drawbacks: traditional luminous floats mostly use fluorescent paint or ordinary LED light sources. Fluorescent paints experience rapid brightness decay and short duration, typically showing a significant decrease in brightness after 3-4 hours, failing to meet the needs of all-night fishing; ordinary LED light sources mostly emit light in one direction, resulting in a limited illumination range, easily creating blind spots, and the color of the light source can easily disturb fish, affecting their concentration.

[0003] Meanwhile, existing float charging systems with integrated lighting are poorly designed and lack robust charging protection mechanisms, frequently resulting in overcharging, shortening lithium battery life, and even posing safety hazards. Furthermore, current float lighting controls are mostly manual switches or simple light controls, unable to automatically activate according to changes in the water environment, leading to missed opportunities to set the hook. These defects severely impact the fishing experience and the practicality of the floats. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems by providing an infrared supplementary lighting float. By integrating an infrared lighting device and an intelligent control circuit, it achieves accurate bite detection in low-light environments, making it suitable for night fishing or fishing in low-light conditions. It can effectively improve the angler's accuracy in judging the fish situation.

[0013] Furthermore, the lithium battery charging circuit includes a status indicator unit, comprising: a blue fully charged indicator and a red charging indicator;

[0014] A 1K current-limiting resistor for the charging indicator is connected in series in the indicator light circuit.

[0015] Furthermore, the working logic of the infrared lighting control circuit is as follows: the gold-plated conductive needle detects the signal amplified by the 51K current-limiting resistor and the S9015 signal detection transistor, which drives the SMMBT3906LT3 switching transistor to conduct, thereby energizing the infrared lamp.

[0016] When the 0805-PTSMD021 photodiode detects ambient light, it forcibly shuts down the SMMBT3906LT3 switching transistor.

[0020] The SMMBT3906LT3 switching transistor has a 100K transistor pull-up resistor and a 1K negative signal current-limiting resistor connected in series at its base.

[0021] Furthermore, the inner wall of the mounting groove is provided with a waterproof sealing ring that covers the gold-plated conductive pins on the edge of the circuit board.

[0022] The advantages of this invention compared to existing technologies are: it uses multiple infrared LEDs arranged in a 360-degree pattern to eliminate blind spots; it avoids overcharging through three-level charging protection, extending battery life; and it utilizes a combination of conductivity detection and light control to keep the float constantly lit, ensuring that the opportunity to lift the rod is not missed and enhancing the night fishing experience.

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] 6. Working principle of this utility model:

[0027] This invention achieves stable operation of an infrared supplementary lighting float through the organic combination of the outer shell 100, the circuit board 200, and the lithium battery. Its core technical principle is as follows:

[0028] In the power supply and charging system, a 5V mobile phone charger is connected to the TYPE-C 6P USB charging port 3. The input voltage is filtered by a 0.1uf capacitor 6 and then sent to the TC4056 lithium battery charging chip 9. The chip sets the charging current through a 3K charging current setting resistor 7. When the lithium battery voltage is below 3V, the chip automatically enters a pre-charging state, limiting the initial charging current through a 0.4R charging current limiting resistor 8. When the voltage rises above 3V, it switches to a constant current charging mode, at which point the 5.1K resistors 4 and 5 act as voltage dividers for stabilization. When the battery is close to saturation, the chip switches to a constant voltage charging mode, and the charging current gradually decreases. During charging, the red charging indicator 13 is illuminated by current obtained through the charging indicator current limiting resistor 12. After full charge, the blue fully charged indicator 11 is turned on, enabling visual monitoring of the charging status. The entire charging process is protected by a multi-level protection mechanism to ensure charging safety.

[0029] In terms of infrared lighting control, when the gold-plated conductive needle 2 contacts a conductive fluid such as water, a weak current flows through the 51K current-limiting resistor 18 into the base of the S9015 signal detection transistor 16. The 620K S9015 signal pull-up resistor 21 provides a stable bias for the transistor. After the signal is amplified by the transistor, it is transmitted to the base of the SMMBT3906LT3 switching transistor 14 through the 1K negative signal current-limiting resistor 20. The 100K switching transistor pull-up resistor 19 ensures reliable conduction of the switching transistor. At this time, the lithium battery voltage is regulated by the 662K Zener diode 15 and drives eight 2835 infrared LEDs 1 to light up through the 2.7R infrared current-limiting resistor 17, achieving 360-degree illumination.

[0030] When the 0805-PTSMD021 photodiode 10 detects sufficient ambient light intensity, its forward conduction generates a signal that pulls up the base potential of the switching transistor 14, forcing the transistor to turn off and automatically turning off the infrared LED 1, thus achieving adaptive light control. The 1.252P battery socket 22 reliably connects the lithium battery to the circuit board 200, ensuring stable power supply to the entire circuit system.

[0031] 7. Implementation method:

[0032] The infrared supplementary lighting float of this embodiment includes a shell 100, a circuit board 200, and a lithium battery. The shell 100 is injection molded from ABS material, with a hanging ring 101 integrally formed on the top for connecting the fishing line. The interior has a stepped mounting groove 102, and the inner wall of the mounting groove 102 is embedded with a silicone waterproof sealing ring to ensure a waterproof rating of IP67.

[0033] The circuit board 200 is made of FR-4 fiberglass board, measuring 35mm × 12mm, and is fixed in the mounting slot 102 by a snap-fit ​​structure. Eight 2835 infrared LED beads 1 are symmetrically soldered to the inner and outer edges of the circuit board 200, with four beads on each side arranged at a 90-degree angle to achieve 360-degree illumination without blind spots. A gold-plated conductive pin 2 is soldered to one end of the circuit board 200, with its tip extending 1.5mm beyond the bottom of the outer casing 100, and tightly fitting into the waterproof sealing ring within the mounting slot 102.

[0034] The lithium battery charging circuit consists of: a TYPE-C6P USB charging port 3 soldered to the top edge of the circuit board 200, with a 0.1uf capacitor 6 connected in parallel inside; 5.1K resistors 4 and 5 connected in series to the voltage detection pin of the charging port 3; a TC4056 lithium battery charging chip 9 soldered to the middle of the circuit board 200, with its VCC pin connected to the charging port 3 through a 0.4R charging current limiting resistor 8, and its PROG pin connected to a 3K charging current setting resistor 7 to ground; a red charging indicator light 13 and a blue fully charged indicator light 11 soldered side by side in the middle area of ​​the circuit board 200, and connected to the STAT1 and STAT2 pins of the chip through a 1K charging current limiting resistor 12, respectively.

[0035] In the infrared lighting control circuit: 0805-PTSMD021 photodiode 10 is soldered to the edge of circuit board 200, and its output terminal is connected to the base of S9015 signal detection transistor 16. The base is also connected to the power supply through 620K S9015 signal pull-up resistor 21; the collector of S9015 signal detection transistor 16 is connected to the base of SMMBT3906LT3 switching transistor 14 through 1K negative signal current limiting resistor 20. The base of the switching transistor is also connected to ground through 100K switching transistor pull-up resistor 19; 662K Zener diode 15 is connected in parallel between the power input terminal and ground; eight infrared LEDs are divided into two groups, and each group is connected in series to the collector of switching transistor 14 through 2.7R infrared current limiting resistor 17.

[0036] The lithium battery is a 3.7V 450mAh polymer lithium battery, connected to the circuit board 200 via a 1.252P battery socket 22. The battery capacity supports continuous lighting time of ≥12 hours. When the float enters the water, the gold-plated conductive needle 2 detects the water's conductivity signal, which is amplified by the circuit and drives the infrared LED 1 to light up. When the ambient light intensity is ≥50 lux, the photodiode 10 triggers the switch to cut off, and the LED automatically turns off.
