[0002] In the mining industry, lighting equipment not only impacts the brightness and safety of the work environment but also directly affects energy consumption and operating costs. Traditional mining lamps often use fixed brightness, without the ability to flexibly adjust brightness according to actual needs. This not only results in unnecessary energy waste when light demand is low, but can also affect workers' visual comfort and even damage their eyesight due to excessive light intensity. Furthermore, traditional lighting control systems are often complex, difficult to adjust, and lack efficient energy-saving mechanisms.

These chips, with their high precision, low power consumption, and strong programmability, provide powerful technical support for intelligent lighting control and efficient energy conservation.

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1
[0020] This embodiment provides an energy-efficient mining lamp that is easy to adjust, including a battery circuit, a headlight control circuit, a small light control circuit, and a light adjustment circuit. The battery circuit provides a VCC power supply.
[0021] like Figure 1As shown, the light adjustment circuit includes a counter U1 capacitor C4, a resistor R14 and a switch button KEY1. The reset terminal RST of the counter U1 is connected to the VCC power supply through the capacitor C4, the clock input terminal GLK of the counter U1 is connected to the VCC power supply through the switch button KEY1, and the clock input terminal GLK of the counter U1 is grounded through the resistor R14. The decoding output terminals 1, 3, 5, 7, and 9 of the counter U1 output control signals out_L, and the decoding output terminals 0, 2, 4, 6, and 8 of the counter U1 output control signals out_H. The control signal out_H is used to drive the headlight control circuit to operate, and the control signal out_L is used to drive the small light control circuit to operate.
[0022] In this embodiment, the CD4017 chip used in the counter U1 is a decimal counter with 10 decoding output terminals. The clock input terminal GLK of the CD4017 receives a rising edge trigger to count. When the clock disable terminal CKEN is at a high level, the counting input is invalid. Whenever the clock input terminal GLK receives a valid clock pulse rising edge, the counter will increment. When the counter reaches 9, the next pulse will return it to 0 and restart counting. At the same time, when the reset terminal RST is at a low level, the counter will immediately return to 0. CD4017 has 10 decoding output terminals (0 to 9), corresponding to the decimal numbers 0 to 9 respectively. When the counter reaches a certain value, the corresponding decoding output terminal will output a high level, and the rest will be low levels.
[0023] Each time the switch button KEY1 is actuated, the clock input GLK of counter U1 receives a high-level signal and counts once. This means the odd-numbered and even-numbered decoding outputs alternately output high-level signals, driving the headlight control circuit and the low-light control circuit, respectively. Switching between the high and low lights is accomplished with a simple button press. The high lights have higher brightness and consume more power than the low lights, allowing workers to switch to the high lights during normal operations and to the low lights at other times, saving power.
[0024] Further, if Figure 2As shown, the headlight control circuit includes a transistor Q3, a transistor Q4, a comparator U2, a MOS transistor Q1 and a headlight LED1. The base of the transistor Q3 is connected in series with a resistor R1 and receives a control signal out_H. The emitter of the transistor Q3 is grounded. The collector of the transistor Q3 is connected to the base of the transistor Q4 through a resistor R2. The emitter of the transistor Q4 is connected to the VCC power supply. The collector of the transistor Q4 is connected in series with resistors R3 and R4 and then grounded. The non-inverting input of the comparator U2 is connected to the connection point of the resistors R3 and R4. The inverting input of the comparator U2 is connected to the source of the MOS transistor Q1. The output of the comparator U2 is connected to the gate of the MOS transistor Q1 through a resistor R5. The source of the MOS transistor Q1 is grounded through a resistor R6. The drain of the MOS transistor Q1 is connected to the cathode of the headlight LED1. The anode of the headlight LED1 is connected to the VCC power supply.
[0025] In this embodiment, when the control signal out_H is high, transistor Q3 is turned on, pulling down the base potential of transistor Q4. Transistor Q4 then conducts, and the voltage at the non-inverting input of comparator U2, after being divided by resistors R3 and R4, becomes greater than the voltage at the inverting input. Comparator U2 outputs a high signal, turning on MOS transistor Q1, thereby illuminating headlight LED 1. When the control signal out_H is low, transistor Q3 and thus transistor Q4 are turned off. The voltage at the non-inverting input of comparator U2 reaches ground, and comparator U2 outputs a low signal, turning off MOS transistor Q1, and thus preventing headlight LED 1 from illuminating. The headlight control circuit provides a constant current operating environment for headlight LED 1, ensuring stable illumination.
[0026] Further, if Figure 3 As shown, the small light control circuit includes a MOS transistor Q2, a small light LED2, a resistor R7 and a resistor R8. The gate of the MOS transistor Q2 is connected in series with the resistor R7 and receives the control signal out_L. The source of the MOS transistor Q2 is grounded. The drain of the MOS transistor Q2 is connected to the cathode of the small light LED2 through the resistor R8. The anode of the small light LED2 is connected to the VCC power supply.
[0027] In this embodiment, when the control signal out_L is high, the MOS transistor Q2 is turned on, thereby driving the small light LED2 to emit light. When the control signal out_L is low, the MOS transistor Q2 is also turned off, and the small light LED2 does not emit light.
[0028] Further, if Figure 1As shown, the battery circuit includes a battery base BAT, a transistor Q5, and a MOS transistor Q6. The base of the transistor Q5 is connected to the positive electrode of the battery base BAT through a resistor R11. The emitter of the transistor Q5 is grounded. The collector of the transistor Q5 is connected to the gate of the MOS transistor Q6. The drain of the MOS transistor Q6 is connected to the positive electrode of the battery base BAT. The source of the MOS transistor Q6 is connected to the gate of the MOS transistor Q6 through a resistor R9. The source of the MOS transistor Q6 outputs the VCC power supply. The negative electrode of the battery base BAT is grounded.
[0029] Furthermore, this embodiment also includes an automatic switching circuit, such as Figure 4 As shown, the automatic switching circuit includes a resistor R10, a resistor R12, a resistor R13 and a comparator U3. The inverting input terminal of the comparator U3 is connected to the VCC power supply through the resistor R10, the first end of the resistor R12 is connected to the cathode of the headlight LED1, the second end of the resistor R12 is grounded through the resistor R13, the second end of the resistor R12 is connected to the non-inverting input terminal of the comparator U3, and the output terminal of the comparator U3 is connected to the clock input terminal GLK of the counter U1.
[0030] In this embodiment, if the headlight LED 1 is currently operating and the battery level drops to a preset value, it automatically switches to low-light operation, extending the operating time. As the miner's lamp is used, the battery level continuously decreases, and the voltage at the inverting input of comparator U3 continuously decreases. Since the constant current source connected to the non-inverting input of comparator U3 serves as a reference voltage, it remains constant. When the battery level drops to a certain preset value, the voltage at the inverting input of comparator U3 becomes less than the voltage at the non-inverting input. Comparator U3 outputs a high-level signal, causing counter U1 to increment by 1. The even-number decoder output changes from a high-level signal to a low-level signal, and the odd-number decoder output changes from a low-level signal to a high-level signal. At this point, because the headlight control circuit stops operating, the voltage at the inverting input of comparator U3 becomes greater than the voltage at the non-inverting input. Comparator U3 outputs a low-level signal, completing a complete high-level pulse.
[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
