Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings, i.e., embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element. The terms "upper," "lower," "left," "right," and the like are used for convenience of description based on the orientation or positional relationship shown in the drawings, and do not denote or imply that the devices or elements in question must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting of the patent. The terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "a plurality of" is two or more, unless specifically defined otherwise.

In order to describe the technical scheme of the invention, the following description is made with reference to specific drawings and embodiments.

As shown in fig. 1, a first aspect of an embodiment of the present application proposes a driving circuit including a driving module 1, a detecting module 2, a control module 3, and a light emitting module 4. The output end of the driving module 1 is connected with the power input end of the light emitting module 4, the input end of the detecting module 2 is connected with the input end of the driving module 1, and the output end of the detecting module 2 is connected with the control module 1.

The driving circuit can be arranged in any lighting lamp, and when the lighting lamp provided with the driving circuit breaks down, the position information of the fault lamp sent to the terminal equipment by the driving circuit can be used for timely determining the fault lamp. For example, the lighting fixtures may be roadside or in-cell lights, office building lights, and the like.

The input end of the driving module 1 is used for being connected with a first power supply, and when the first power supply connected with the driving module 1 is normal, the driving module 1 controls the light emitting module 4 to emit light, so that the lighting function is realized. It can be understood that, here, the first power source is normal and may mean that the voltage value of the first power source is greater than the preset voltage value, and, for example, when the first power source in the present application refers to 220V (volt) mains supply, assuming that the preset voltage value is 198V, when the input voltage of the input end of the driving module 1 is greater than 198V, it indicates that the accessed first power source is normal, and the light emitting module 4 may emit light normally; when the input voltage at the input end of the driving module 1 is less than or equal to 198V, the first power supply connected is abnormal, the light emitting module 4 emits light abnormally, and the first power supply connected is possibly damaged by human or caused by natural disasters.

In order to enable a user to find the specific position of the fault lamp in time, the detection module 2 and the control module 3 provided in the embodiment of the application can be matched for use: the detection module 2 detects an input voltage at the input end of the driving module 1, and when the input voltage is detected to be smaller than or equal to a preset voltage value, the detection module 2 sends a control signal to the control module 3, and the control module 3 sends position information to terminal equipment (such as a mobile phone, a computer and the like) after receiving the control signal. It is understood that the location information here is the location of the lighting fixture where the driving circuit is located. The terminal device is the device in communication connection with the control module.

The detection module 2 detects the input voltage of the input end of the driving module 1, namely, the first power supply is connected to the driving module 1 and is connected to the detection module 2. The control signal finally output from the detection module 2 to the control module 3 may be a high-low level signal. For example, when the detection module 2 detects that the input voltage at the input end of the driving module 1 is less than or equal to a preset voltage value, a low-level signal is sent to the control module 3, and after the control module receives the low-level signal, position information is collected and sent to the terminal equipment; when the detection module 2 detects that the input voltage at the input end of the driving module 1 is normal, a high-level signal is sent to the control module 3, and the control module does not collect position information after receiving the high-level signal. In this way, the detection module 2 can detect the input voltage of the input end of the driving module 1 in real time, so that when the input voltage is abnormal, a user can find out fault position information in time.

In one example, as shown in fig. 2, the detection module 2 may include: the device comprises a first resistor R1, a second resistor R2, a first capacitor C1, a zener diode Z1, a second capacitor C2 and a linear optocoupler U1. One end of the first resistor R1 is used for being connected to a first power supply, the other end of the first resistor R1 is connected with one end of the second resistor R2, a first end (U1 a shown in fig. 2) of the linear optocoupler U1 is respectively connected with one end of the second resistor R2, an anode of the first capacitor C1, one end of the zener diode Z1 and one end of the second capacitor C2, a second end (U1 b shown in fig. 2) of the linear optocoupler U1 is respectively connected with the other end of the second resistor R2, a cathode of the first capacitor C1, the other end of the zener diode Z1 and the other end of the second capacitor C2, and a third end (U1C shown in fig. 2) and a fourth end (U1 d shown in fig. 2) of the linear optocoupler are connected with the control module 3. The input voltage is divided by the first resistor R1 and the second resistor R2, the voltage at two ends of the second resistor R2 after the voltage division passes through the first capacitor C1, the voltage is stabilized by the voltage stabilizing diode Z1 and then passes through the second capacitor C2, and finally the voltage is output to the control module 3 through the linear optocoupler U1.

Alternatively, the linear optocoupler U1 may be a PC817B optocoupler. Because PC817B photoelectric coupler's volume is less and interference killing feature is stronger, can reduce driving circuit's design volume, improve driving circuit's interference killing feature.

The control module 3 can collect the position information of the driving circuit according to the control signal output by the detection module 2, and send the collected position information to the terminal device for the user to check.

Optionally, the control module 3 may establish communication connection with the terminal device through WiFi technology or 3G/4G/5G wireless technology.

In one example, the control module 3 may include a control chip 301 and a positioning unit 302, the control chip 301 being electrically connected to the output of the detection module 2 and the positioning unit 302, respectively. After receiving the control signal output by the detection module 2, the control chip 301 sends an acquisition instruction to the positioning unit 302, and after receiving the acquisition instruction, the positioning unit 302 acquires the position information of the driving circuit, and sends the position information to the control chip 301, and the control chip 301 sends the position information to the terminal equipment for the user to check.

Alternatively, the positioning unit 302 may be a global positioning system (Global Positioning System, GPS).

Illustratively, the positioning unit 302 may include a positioning chip having 7 pins as shown in fig. 3, and the control chip 301 may be a chip having 48 pins as shown in fig. 6. The serial data input end gps_rx, that is, a GPS signal receiving end (receiver, RX), and the output end gps_tx, that is, a GPS signal output end (transmitter, TX), of the positioning chip are respectively connected with the UTXD2 pin and the UTXD2 pin of the control chip 301, the input/output Ports GPIO1 (General Purpose I/O Ports, GPIO) and GPIO2 Ports of the positioning chip are respectively connected with the GPIO1_a pin and the GPIO2_a pin of the control chip 301, and the gps_vcc, that is, the port to which the power supply Voltage (VCC) is connected with the gps_on of the control chip 301. After the control chip 301 accesses the control information, the positioning chip is started through the gps_on pin, then an acquisition instruction is input to the gps_rx end of the positioning chip through the URXD2 pin, the positioning chip acquires position information based ON the acquisition instruction, and the positioning chip sends the position information to the UTXD2 pin of the control chip 301 through the gps_tx end, and the control chip 301 sends the position information to the terminal device. Here, it should be noted that the control chip 301 is communicatively connected to the terminal device, and the control chip 301 may transmit the location information to the terminal device through a 2G or 4G communication network. Other chips may be used for the positioning chip and the control chip 301, and the present application is not limited in this regard.

The light emitting module 4 may be a single light emitting diode (Light Emitting Diode, LED) lamp or a lamp panel assembled from a plurality of LED lamps.

According to the driving circuit provided by the embodiment of the application, the detection module 2 can detect the input voltage of the input end of the driving module 1 in real time, when the detection module 2 detects that the input voltage is abnormal, a control instruction can be sent to the control module 3, so that the control module 3 can send the position information of the fault lamp to the terminal equipment based on the control signal, and a user can timely determine the position of the fault lamp according to the position information in the terminal equipment. And in the drive circuit that this application provided, first power is connected with drive module and detection module's input simultaneously, and first power is when the input voltage to drive module 1 promptly, and detection module 2 can detect this input voltage always for detection module 2 can discover the illumination lamps and lanterns that produce the illumination trouble fast. In summary, the driving circuit provided by the application can detect the input voltage of the input end of the driving module 1 in real time, and when detecting the input voltage fault, the fault position information can be timely sent to the terminal equipment, so that a user can find the position information of the lighting lamp generating the lighting fault through the terminal equipment, and the user does not need to confirm and report by manpower, thereby saving time.

When the voltage input from the driving module 1 fails, the light emitting module 4 cannot emit light normally. Therefore, the driving circuit provided in this application embodiment may further include an emergency module 5 as shown in fig. 5, where an input end of the emergency module 5 is connected to an output end of the detection module 2, an output end of the emergency module 5 is connected to a power input end of the light emitting module 4, the emergency module 5 also receives a control signal output by the detection module 2, and after the emergency module 5 receives the control signal, the emergency module 5 accesses a second power supply to the power input end of the light emitting module 4, so that the light emitting module 4 can emit light based on the second power supply. In this way, the light emitting module 4 can emit light normally even when the input voltage of the driving module 1 is abnormal.

In one example, the emergency module 5 may be a chip with 14 pins as shown in fig. 6, where the P25 pin of the emergency module 5 is used to access the control signal ac_de output by the detection module 2, where ac_de refers to an AC valid display data strobe signal, and after receiving the control signal ac_de, the emergency module 5 controls the second power supply to access the power input terminal of the light emitting module 4 through the P55/OSI pin, so that the light emitting module 4 may also implement light emission when the input voltage of the driving module 1 fails.

When the second power is connected, the light emitting module 4 is always in a charging state, i.e. the light emitting module 4 emits light all the time, so that the energy consumption is relatively high. In order to reduce energy consumption, in an example, the driving circuit provided in the embodiment of the present application may further include a first sensing module 6 and a switching module 7 as shown in fig. 7, where the first sensing module 6 is connected to the power input terminal of the light emitting module 4 through the switching module 7. The first sensing module 6 is configured to detect whether an object approaches, and send a sensing signal to the switch module 7 through sensed information, so as to control the on/off state of the switch module 7. For example, when the first sensing module 6 senses that an object is approaching, the first sensing module 6 outputs a first sensing signal to the switch module 7, the switch module 7 is turned on, and the light emitting module 4 can be connected to the second power source and emit light. When the first sensing module 6 does not sense that an object is approaching, the first sensing module 6 outputs a second sensing signal to the switch module 8, the switch module 8 is turned off, the light emitting module 4 is not connected to the second power supply, and the light emitting module 4 is turned off (or does not emit light).

For example, when the maintenance personnel reaches the sensing range of the failed lighting fixture (it is understood that the sensing range refers to the distance range that the first sensing module 6 can sense), the first sensing device 6 sends a high level signal to the switch module 7, the switch module 7 is turned on, the power access terminal of the light emitting module 4 can receive the second power, and the light emitting module 4 emits light.

Alternatively, the first sensing means 6 may be an infrared sensing means.

Alternatively, the switching module 7 may be a field effect transistor (Metal Oxide Semiconductor Field Effect Transistor, MOS) as shown in fig. 8. When the MOS tube receives the high-level signal, the MOS tube is conducted, and when the MOS tube receives the low-level signal, the MOS tube is turned off.

In another example, the driving circuit provided in the embodiment of the present application may further include a second sensing module 8 as shown in fig. 9, where a first switch may be disposed in the second sensing module 8, and the second sensing module 8 is connected to a power input end of the light emitting module 4, and controls on/off of the light emitting module 4 through on/off of the first switch. When the second sensing module 8 senses that an object is close, the first switch is arranged in the second sensing module 8 to be conducted, and the second sensing module 8 outputs a first sensing signal to control the light emitting module 4 to emit light. When the second sensing module 8 does not sense that an object is close, the first switch is arranged in the second sensing module 8 to be turned off, and the second sensing module 8 outputs a second sensing signal to control the light emitting module 4 to be turned off.

Alternatively, the second sensing module 8 may be a microwave inductor in which the first switch is provided.

The driving circuit in this embodiment is through setting up detection module 2, control module 3, emergent module 5 and sensing module for the illumination lamps and lanterns of using this driving circuit can realize shining under the condition of commercial power trouble, owing to be provided with sensing module, can make the illumination lamps and lanterns realize energy-conserving mode based on the information that sensing module sensed, and light emitting module 4 lights when someone is close promptly, and light emitting module 4 goes out when unmanned is close. Therefore, the lamp in the driving circuit can normally illuminate and can perform emergency illumination, the lamp cost of the lighting equipment is effectively reduced, and the lamp can be intelligently controlled based on signals sensed by the sensing module in an emergency illumination mode, so that electric energy is saved.

It can be appreciated that in the emergency lighting mode, since the first sensing module 6 or the second sensing module 8 is provided in the embodiment of the present application, intelligent control can be achieved during emergency lighting. In the normal illumination mode, the first sensing module 6 or the second sensing module 8 is provided in the embodiment of the application, so that intelligent control can be realized under normal illumination. For example, when the first sensing module 6 detects that a person passes by, the switch module 7 is turned on, and the voltage output by the driving module 1 may be connected to the power input end of the light emitting module 4, so that the light emitting module 4 emits light.

The second embodiment of the present application further provides a lighting fixture, including the driving circuit according to any one of the first optional modes of the first embodiment, where the driving circuit may be integrally disposed in a housing, and the housing may be installed inside the lighting fixture. Because the lighting lamp adopts all the technical schemes of all the embodiments, the lighting lamp at least has all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted here.
