Description

Technical Field

[0001] The present invention relates to a voltage boost driving device, in particular to a power supply device used in the field of small lighting products, which is mainly capable of effectively and accurately controlling power output, thereby maintaining the service life of the small lighting products instead of shortening them. Background Art

[0002] Among the many luminous products nowadays, most have the function of adjusting the brightness of light according to needs, environment, etc. However, the power sources used in general luminous products are mostly dry batteries, lithium batteries, etc. These power supply components can only output fixed currents, but some luminous products require extremely large currents. General power supply components alone cannot make the luminous products produce extremely bright brightness. Therefore, a boost circuit device is provided in the luminous product. The boost circuit device can increase the DC voltage at the input end, so that the fixed power supply component can also generate a larger power output.

[0003] However, the output voltage of the output end of a general boost circuit device must be greater than the input voltage of the input end in order to operate normally. However, this also indirectly causes that when the power is supplied, the use time of the light-emitting product cannot reach a balance due to the increase in current, resulting in a shortened battery life and even affecting the brightness of the light-emitting product. Please refer to patent number TWI527497 "Light-emitting diode drive system and control module", which includes a boost circuit and a control module. The boost circuit selectively converts a DC power supply voltage into an output voltage greater than the power supply voltage and DC according to a control signal, and provides an output current to drive the light-emitting diode to emit light; and the control module generates a pulse width modulated control signal according to an input voltage related to the power supply voltage, and the duty cycle of the control signal changes monotonically as the input voltage increases.

[0004] Although the above-mentioned previous cases improve the problem by changing the pulse width, the changed pulse width still maintains a fixed bandwidth and cannot be changed according to the strength of the battery power supply, the strength of the light, and the lighting time requirements. In addition, the battery power, bandwidth, and frequency are fixed. If the product is to produce high-intensity light lumens, it will only accelerate the shortening of the battery life, which is more obvious when there is a boost circuit setting, and even affect the light intensity of the luminous product. Therefore, how to improve the power provided by the power supply device to maintain the service life and not affect the light intensity of the luminous product is an important issue. Utility Model Content

[0005] The main purpose of the present invention is to allow general luminous products to effectively and accurately control the output of electricity during use, thereby maintaining the service life of the luminous products. It improves the existing technology that the bandwidth of the output power can only be at a fixed frequency, and cannot be effectively adjusted and accurately controlled, resulting in a shortened service life of the power supply device and even affecting the light intensity of the luminous product. To this end, the inventors of the present invention have tried their best to achieve the purpose and effect of the aforementioned creation. The present invention is a voltage boost driving device, which is mainly electrically connected to a light-emitting component and drives the light-emitting component to operate, which includes: a power supply component that outputs alternating current or direct current; a microcontroller, which is installed on a circuit board and electrically connected to the power supply component, and the microcontroller further has a built-in control unit, an input unit and an output unit. The input unit receives the power input by the power supply component when it is alternating current, and uses the control unit to adjust, convert, and change the voltage, pulse width, and frequency of the power, and the output unit outputs the power adjusted and converted by the control unit; a boost circuit component, which is installed on the The circuit board is electrically connected to the power supply component and the microcontroller. The boost circuit component further has a built-in receiving unit, a sending unit and a boost control unit. The receiving unit receives the power output by the output unit of the microcontroller and directly receives the power of the power supply component when it is direct current. The boost control unit adjusts the working cycle and bandwidth of the power to obtain a boosted power. The boosted power is transmitted by the sending unit to the light-emitting component and driven to emit light; and a first feedback circuit and a second feedback circuit. The first feedback circuit serves as an electrical connection bridge between the power supply component and the microcontroller, and the second feedback circuit serves as an electrical connection bridge between the boost circuit component and the microcontroller.

[0006] When the power supply component outputs alternating current, the power is transmitted to the first feedback circuit for gain and distortion suppression before being transmitted to the microcontroller; when the power supply component outputs direct current, the power is directly transmitted to the boost circuit component, and part of the boosted power obtained after adjustment by the boost control unit is transmitted to the second feedback circuit for gain and distortion suppression before being transmitted to the microcontroller, and the other part of the boosted power drives the light-emitting component to operate; wherein, the setting of the microcontroller can be used to most accurately adjust, set, and change the power supply component, so as to supply the power bandwidth required by the light-emitting component, thereby achieving the best illumination and maintaining the service life of the power supply component.

[0007] According to the above definition of the present invention, the microcontroller can be used to most accurately control the power output by the power supply component, and combined with the boost technology of the boost circuit component, the power supplied by the power supply component can be the most appropriate output and the best performance can be obtained, so that the light-emitting component can be maintained at the optimal lumen value in various intensities of lighting, and will not shorten the service life of the power supply component. Compared with the previous cases listed in the prior art, the prior art can only be used under the limited power of the battery and the fixed bandwidth supply, and it is easy to cause the battery life to be shortened at a high lumen output. The present invention can adjust and change the frequency, bandwidth, etc. of the battery power supply under the setting of the microcontroller, so that the light-emitting component can operate with the most appropriate power supply in any intensity of lighting, thereby maintaining the service life of the battery. It can be seen that the present invention can be said to be a very practical and progressive creation, which is worthy of promotion by the industry and disclosure to the general public.

[0009] In order to clearly illustrate the above-mentioned purpose and effect achieved by the present invention, the features and effects of the embodiments of the present invention are described in detail with reference to the accompanying drawings. Figure 1As shown, a voltage boost driving device of the present invention is mainly electrically connected to a light-emitting component 100 and drives the light-emitting component 100 to operate and transmit light, and includes: a power supply component 1 for supplying AC or DC power; a microcontroller 2, which is installed on a circuit board 3 and electrically connected to the power supply component 1, and the microcontroller 2 further has a built-in control unit 21, an input unit 22 and an output unit 23. The input unit 22 receives the power input by the power supply component 1 when it is AC power, and adjusts and converts it with the control unit 21. , changing the voltage, pulse width and frequency of the electric power, and the output unit 23 outputs the electric power adjusted and converted by the control unit 21; a boost circuit component 4, which is installed on the circuit board 3 and is electrically connected to the power supply component 1 and the microcontroller 2, and the boost circuit component 4 further has a built-in receiving unit 41, a sending unit 42 and a boost control unit 43, the receiving unit 41 receives the electric power output by the output unit 23 of the microcontroller 2 and directly receives the electric power of the power supply component 1 when it is direct current, and the above-mentioned electric power is adjusted by the boost control unit 43 The entire working cycle and bandwidth are used to obtain a boosted power 44, and the boosted power 44 is transmitted by the sending unit 42 to the light-emitting component 100 and driven to emit light; and a first feedback circuit 5 and a second feedback circuit 6 are installed on the circuit board 3, and the first feedback circuit 5 is used as an electrical connection between the power supply component 1 and the microcontroller 2, and the second feedback circuit 6 is used as an electrical connection between the boost circuit component 4 and the microcontroller 2. When the power of the power supply component 1 is AC, the power is transmitted to the first feedback circuit 5 for gain and distortion suppression before being transmitted to the microcontroller The microcontroller 2 is used for the power supply component 1. When the power is direct current, the power is directly transmitted to the boost circuit component 4, and part of the boost power 44 obtained after adjustment by the boost control unit 43 is transmitted to the second feedback circuit 6 for gain and distortion suppression and then transmitted to the microcontroller 2, and the other part drives the light-emitting component 100 to operate; wherein, the setting of the microcontroller 2 can be used to most accurately adjust, set, and change the power supply component 1, so as to supply the power bandwidth required by the light-emitting component 100, thereby achieving the best illumination and maintaining the service life of the power supply component 1.

[0010] According to the above description, the power supply assembly 1 of the present invention can be divided into two parts for power supply and transmission. The power supply assembly 1 further includes a power supply 11 and a battery supply 12. The power supply 11 is electrically connected to the first feedback circuit 5, and the battery supply 12 is electrically connected to the microcontroller 2. The battery supply 12 supplies direct current, and the power supply 11 supplies alternating current. The power supply assembly 1 supplies power by outputting power through either the power supply 11 or the battery supply 12. In simple terms, the battery supply 12 is a dry cell, a lithium battery, or the like for supplying direct current, and the power supply 11 is a mains, or the like for supplying alternating current. The battery supply 12 or the power supply 11 can also be selected for power supply and transmission.

[0011] According to the above instructions and see Figure 1 As shown, basically two paths are used for explanation. The first path is that after the power supply element 11 in the power supply component 1 outputs power, the power will first enter the first feedback circuit 5, and the characteristics of the first feedback circuit 5 are used to suppress the distortion of the initial power and adjust the bandwidth of the power. After completion, it is transmitted to the microcontroller 2. After entering the microcontroller 2, the power is adjusted and changed by the setting of the control unit 21. The adjusted power is output from the output unit 23 to the boost circuit component 4, and the boosted power 44 is formed under the boost adjustment of the boost circuit component 4. At this time, the boosted power 44 obtained is The optimal voltage, current, bandwidth, and frequency are suitable for driving the light-emitting component 100, and there will be no excessive or redundant power supply that shortens the life of the power supply component 1. During the process of the boost power 44 being delivered to the light-emitting component 100 for driving, the local boost power 44 will also be diverted and transmitted to the second feedback circuit 6. The function of the second feedback circuit 6 is the same as that of the first feedback circuit 5. The local boost power 44 will be adjusted and fed back to the microcontroller 2 for reuse. Through repeated use under the setting of the first path, the power supply of the power supply unit 11 in the power supply component 1 can be optimally utilized.

[0012] Continuing with the second path of the present invention described above, when the output object is the battery supply component 12 in the power supply component 1, the power will be directly transmitted to the boost circuit component 4 for use. After the boost adjustment of the boost circuit component 4, part of the boost power 44 is supplied to the light-emitting component 100 for driving use, and the other part of the boost power 44 is fed back to the microcontroller 2 for reuse after passing through the second feedback circuit 6. In the second path, because the power supply component 1 is the battery supply component 12, the current and voltage are not large, so it can be directly supplied and used through the boost adjustment of the boost circuit component 4.

[0013] It is understood that the present invention is mainly based on the configuration of the microcontroller 2, and the power supply component 1 can adjust the power provided by the power supply component 1 to the battery supply component 12 and the power supply component 11, so that the light-emitting component 100 can be driven by the best power. However, in order to allow the battery supply component 12 in the power supply component 1 to assist and slow down the power consumption of the battery supply component 12 when supplying power, a storage capacitor 24 is further built into the microcontroller 2. After the power of the power supply component 11 is transmitted to the microcontroller 2 through the first feedback circuit 5, part of the power of the power supply component 11 is stored in the storage capacitor 24. When only the battery supply component 12 outputs power, the power of the storage capacitor 24 is discharged and assists the power supply of the battery supply component 12. The setting of the storage capacitor 24 can increase the voltage value when the power is output by the output unit 23 of the microcontroller 2, see Figure 1 shown.

[0014] In addition, when the power supply element 11 in the power supply assembly 1 supplies power, power consumption will be generated under the driving of the first feedback circuit 5 and the microcontroller 2. In order to effectively reuse the power, a current amplifier 7 is further provided on the circuit board 3. Figure 1 As for the first path mentioned above, the control unit 21 of the microcontroller 2 transmits part of the power from the output unit 23 to the current amplifier 7, and the current amplifier 7 amplifies the received power and transmits it to the first feedback circuit 5 together with the power of the power supply 11 for adjustment, repeatedly integrating and adjusting the power to achieve effective utilization; and in the configuration of the microcontroller 2 of the present invention, the output unit 23 further includes a D / A conversion terminal 231, a micro-control pulse width modulation terminal 232 and a boost pulse width modulation terminal 233, and the input unit 22 includes two A / D conversion terminals 221, and the two A / D conversion terminals 221 are mainly used to receive the first feedback circuit 5 and the second feedback circuit 6. The transmitted power, the power entering the two A / D conversion terminals 221 is an analog signal, the microcontroller 2 converts it into a digital signal with the control unit 21 and adjusts and changes it, and then outputs it to a suitable position through the D / A conversion terminal 231, the micro-control pulse width modulation terminal 232 and the boost pulse width modulation terminal 233. The D / A conversion terminal 231 and the micro-control pulse width modulation terminal 232 transmit part of the power to the current amplifier 7 so that the power can be reused, and part of the power is transmitted to the receiving unit 41 of the boost circuit component 4 through the boost pulse width modulation terminal 233, and then transmitted after adjustment by the boost control unit 43 and drives the light-emitting component 100 to operate, and is shunted to the second feedback circuit 6 for reuse, see Figure 1 shown.

[0015] Finally, in order to accurately adjust, change, and convert the power supply of the power supply component 1, the present invention further includes a detection group 211 and an adjustment group 212 in the setting of the control unit 21 of the microcontroller 2. The detection group 211 detects the voltage, current, frequency, and bandwidth of the power transmitted from the first feedback circuit 5 and the second feedback circuit 6 to the microcontroller 2, and the adjustment group 212 performs signal adjustment based on the result detected by the detection group 211. After the adjustment of the adjustment group 212 is completed, the signal is sent by the sending unit 42. Through the repeated detection and adjustment of the power by the microcontroller 2, the power driving the light-emitting component 100 can be more precise and accurate, and the battery supply component 12 in the power supply component 1 will not generate excessive consumption in the use of power supply, and the light-emitting component 100 can have the best illumination.
