Description

[0002] At present, due to the requirements of the application scenario, outdoor bullet cameras for security monitoring have very high requirements for the infrared light radiation intensity of the matched dual-light source supplementary light module and the lumen value of white light. At night, in order to obtain better image effects in the three modes of night mode, full-color mode, and intelligent mode of the camera, as long as the structure permits, more infrared lamps and white lamps will be set on the dual-light source supplementary light module as much as possible. However, since the dual-light source supplementary light module is the main heat source and the highest heat source of the camera, when the heat dissipated during its operation is superimposed on the heat generated by the main board, the following problems will occur without special treatment:

The temperature inside the casing is too high, resulting in unstable operation of the camera, abnormal problems such as abnormal, blurred, large thermal noise points, and image flickering in the image, and even the camera crashing in a high-temperature environment. 2.

[0029] Please refer to Figure 1 , Figure 1Schematic diagram of a low-power dual-light source lamp board. This embodiment provides a low-power dual-light source lamp board, which includes a substrate 1 and a plug-in connector J1, a first light source module 2, and a second light source module 3 mounted on the substrate 1. In practical applications, the plug-in connector J1 is used to connect to the control main board of the camera, so that the low-power dual-light source lamp board is controlled by the control main board of the camera. At the same time, the first light source module 2 and the second light source module 3 are respectively connected to the pins of the plug-in connector J1, so that the first light source module 2 and the second light source module 3 are controlled by the control signals sent by the control main board of the camera.

[0030] When the first light source module 2 receives the W-EN control signal sent by the control main board of the camera, the first light source module 2 is in the on state, and the second light source module 3 is in the off state; when the second light source module 3 receives the IR-EN control signal sent by the control main board of the camera, the second light source module 3 is in the on state, and the first light source module 2 is in the off state.

[0031] Please refer to Figure 2 , Figure 2 Schematic diagram of the plug-in connector J1. Specifically, the plug-in connector J1 has a first pin, a second pin, a third pin, a fourth pin, and a fifth pin. Among them, the first pin is used for the digital-to-analog conversion of the plug-in connector J1 and the control main board, the second pin is connected to the second light source module 3, the third pin is connected to the first light source module 2, the fourth pin is connected to the ground terminal, and the fifth pin is connected to the 12V power supply voltage.

[0032] Please refer to Figure 3 , Figure 3Circuit diagram of the first control module. The first light source module 2 includes a first control module 21 and a first light-emitting component 22. Among them, the first control module 21 includes a first filter circuit 211, a control chip U1, a freewheeling module 212 and a sampling module 213. The control chip U1 has a DIM terminal, a VIN terminal, a CSN terminal, a SW terminal and a GND terminal. The DIM terminal of the control chip U1 is a switch enable terminal, and the DIM terminal of the control chip U1 is connected to the third pin of the connector J1, which is used to receive the W-EN control signal sent by the camera control main board. The VIN terminal is the voltage input pin of the control chip U1. One end of the first filter circuit 211 is connected to the fifth pin of the connector J1, and the other end is connected to the VIN terminal of the control chip U1, so that the input 12V power supply voltage enters the control chip U1 after being filtered by the first filter circuit 211. The VIN terminal of the control chip U1 is connected to the SW terminal through the freewheeling module 2112, and the freewheeling module 212 is used to prevent current mutation. The CSN terminal of the control chip U1 is connected to the positive input terminal of the first light-emitting component 22. The CSN terminal of the control chip U1 is the current sampling terminal of the control chip U1, and the sampling module 213 is connected in series between the CSN terminal and the VIN terminal of the control chip U1. The SW terminal of the control chip U1 is connected to the negative input terminal of the first light-emitting component 22. The GND terminal of the control chip U1 is connected to the reference ground.

[0033] In this embodiment, the model of the control chip U1 is PT4115, which is a driving chip with a buck constant current function. The freewheeling module 212 is a diode D1, and the sampling module 213 is a resistor R8. When the DIM terminal of the control chip U1 receives the W-EN control signal sent by the camera control main board, the DIM terminal is at a high level, causing the control chip U1 to work. After the 12V power supply voltage is filtered by the first filter circuit 211, it is input into the control chip U1 from the VIN terminal of the control chip U1. The 12V power supply voltage is converted into a stable DC constant current power supply after passing through the control chip U1, and then output to the first light-emitting component 22 to drive the first light-emitting component 22 to emit light stably. The sampling resistor R18 samples the voltage signal output by the control chip U1 and then inputs it back into the control chip U1, so that the control chip U1 continuously adjusts the output voltage according to the sampled voltage signal.

[0034] In this way, by setting the first control module 21, the input 12V power supply voltage is stepped down after passing through the first control module 21 and is converted into a stable constant current power supply and input to the first light-emitting component 22, avoiding direct input of excessive current to the first light-emitting component 22, effectively preventing the first light source module 2 from overheating, realizing efficient conversion of energy at the same time, reducing energy loss and heat generation, driving the first light source module 2 more efficiently, reducing energy loss, thereby reducing the overall power consumption of the first light source module 2, and effectively reducing the heat generation of the low-power dual-light-source lamp board. In this way, there is no need to additionally use a material with a higher thermal conductivity to dissipate heat from the camera, reducing the assembly steps of the camera and effectively reducing the manufacturing cost.

[0035] Please refer to Figure 4 , Figure 4 is a schematic diagram of the first light-emitting component. Further, the first light-emitting component 22 includes a plurality of first light-emitting elements 221, and the plurality of first light-emitting elements 221 are connected in parallel with each other. In this embodiment, a total of six first light-emitting elements 221 are provided. The positive electrode of one of the first light-emitting elements 221 is connected to the CSN terminal of the control chip U1 to receive the positive output of the first control module; the negative electrode of the first light-emitting element 221 is connected to the SW terminal of the control chip U1 to receive the negative output of the first control module. The remaining five first light-emitting elements 221 are divided into five branches and are connected in parallel to the first light-emitting element 221 connected to the first control module, so that the six first light-emitting elements 221 are divided into six branches and are connected in parallel in sequence.

[0036] By connecting the six first light-emitting elements 221 in parallel, the voltage across each first light-emitting element 221 is equal. That is, in actual use, only the driving voltage required for a single first light-emitting element 221 needs to be provided to light up the six first light-emitting elements 221 connected in parallel. In this embodiment, the forward voltage range of each first light-emitting element 221 is 8.8V - 9.2V, and its luminous flux range is 165LM / W - 170LM / W. That is, when a plurality of first light-emitting elements 221 are connected in parallel, only a power supply voltage of 8.8 - 9.2V needs to be provided to light up the plurality of first light-emitting elements 221 at the same time, thus eliminating the need to increase the power supply voltage secondly, which is beneficial to reducing the manufacturing cost. Secondly, by using the first light-emitting element 221 with lower power and higher luminous intensity, the first light-emitting component 22 ensures its brightness while having lower power consumption. It should be noted that the first light-emitting element 221 is a white light lamp.

[0037] Further, the first filtering circuit 211 includes a first filtering unit 2111 and a second filtering unit 2112. One end of the first filtering unit 2111 is connected to the VIN terminal and the fifth pin of the control chip U1, and the other end is grounded. The second filtering unit 2112 is connected in parallel with the first filtering unit 2111. In this embodiment, the first filtering unit 2111 is a capacitor C7, and the second filtering unit 2112 is a capacitor C6. The capacitor C7 and the capacitor C6 are used to filter high-frequency clutter in the input voltage, making the voltage input to the control chip U1 more stable.

[0038] The first control module 21 further includes a second filtering circuit 214. One end of the second filtering circuit 214 is respectively connected to the SW terminal and the CSN terminal of the control chip U1, and the other end is respectively connected to the positive input terminal and the negative input terminal of the first light-emitting component 22. In this embodiment, the second filtering circuit 214 includes an inductor L1 and a capacitor C8. One end of the inductor L1 is respectively connected to the SW terminal of the control chip U1 and the freewheeling diode D1, and the other end is connected to the negative input terminal of the first light-emitting component 22. The inductor L1 is used for filtering to make the output voltage of the control chip U1 stable. The capacitor C8 is connected in parallel between the positive input terminal and the negative input terminal of the first light-emitting component 22. The capacitor C8 is used for filtering and voltage regulation to reduce interference with the voltage output by the control chip U1.

[0039] The first control module 21 further includes a voltage dividing circuit 215. One end of the voltage dividing circuit is connected to the third pin, and the other end is connected to the DIM terminal of the control chip U1. In this example, the voltage dividing circuit 215 includes a resistor R5 and a resistor R6. One end of the resistor R5 is connected to the DIM terminal of the control chip U1, and the other end is connected to the third pin of the connector J1. One end of the resistor R6 is respectively connected to the resistor R5 and the DIM terminal of the control chip U1, and the other end is grounded. Both the resistor R5 and the resistor R6 are used for voltage division. After the control main board of the camera sends a control signal, the control signal is divided by the resistor R6 and the resistor R5 and then enters the DIM terminal of the control chip U1.

[0040] Please refer to Figure 5 , Figure 5 For the circuit diagram of the second control module. Further, the second light source module 3 includes a second control module 31 and a second light-emitting component 32. The second control module 31 has a voltage input terminal, an enable input terminal, a positive output terminal, and a negative output terminal. The voltage input terminal of the second control module 31 is connected to the fifth pin of the connector J1, the enable input terminal of the second control module 31 is connected to the second pin of the connector J1, the positive output terminal of the second control module 31 is connected to the positive input terminal of the second light-emitting component, and the negative output terminal of the second control module 31 is connected to the negative input terminal of the second light-emitting component 32.

[0041] The 12V power supply voltage is input from the voltage input terminal of the second control module 31. The enable input terminal of the second control module 31 is connected to the control main board of the camera, so as to receive the IR-EN control signal sent by the control main board of the camera, enabling the second control module 31 to work. The 12V power supply voltage is converted into a stable constant current source after passing through the second control module 31, and the stable constant current source is output to the second light-emitting component 32, making the second light-emitting component 32 emit light stably.

[0042] It should be noted that in this embodiment, the circuit structure of the second control module 31 is the same as that of the first control module 21. The difference is that the DIM terminal of the control chip U3 with the label of the second control module, which receives the control signal, is connected to the fifth pin of the connector J1, and it receives the IR-EN control signal sent by the control main board of the camera.

[0043] When the DIM terminal of the control chip U3 receives the IR-EN control signal sent by the control main board of the camera, the DIM terminal is at a high level, enabling the control chip U3 to work. The 12V power supply voltage is filtered by the capacitor C3 and the capacitor C4 and then input into the control chip U3 from the VIN terminal of the control chip U3. The 12V power supply voltage is converted into a stable DC constant current power supply after passing through the control chip U3, and then output to the second light-emitting component 32 to drive the first light-emitting component 32 to emit light stably. The sampling resistor R17 samples the voltage signal output by the control chip U3 and then inputs it back into the control chip U3, enabling the control chip U3 to continuously adjust the output voltage according to the sampled voltage signal.

[0044] Please refer to Figure 6 , Figure 6 which is a schematic diagram of the second light-emitting component. The second light-emitting component 32 includes two groups of light source components 321 connected in parallel. When connecting, the positive pole of one group of light source components 321 is connected to the positive output terminal of the second control module 31, and its negative pole is connected to the negative output terminal of the second control module 31, and the other group of light source components 321 is connected in parallel with it. Each group of light source components 321 includes a plurality of second light-emitting elements 3211 connected in series. In this embodiment, each group of light source components 321 has four second light-emitting elements 3211, and the four second light-emitting elements 3211 are connected in series. It should be noted that the second light-emitting element 3211 is an infrared lamp, and the range of the forward voltage value of the second light-emitting element 3211 is 1.55V - 1.65V.

[0045] Preferably, the connector J1 further includes a sixth pin, and the sixth pin is used to connect the 5V power supply voltage. The voltage input terminal of the second control module 31 is connected to the sixth pin of the connector J1. Since the working voltage required by the second light-emitting component 32 is relatively low, by connecting the 5V power supply voltage, the additional energy loss caused by too large a voltage difference is avoided, thereby further reducing the heat generation of the dual-light-source lamp board.

[0046] Further, each group of light source components 321 further includes a current-limiting resistor 3212, and the current-limiting resistor 3212 is connected in series with four second light-emitting components 3211. The current-limiting resistor 3212 is used to limit the magnitude of the current to avoid damaging the second light-emitting component 3211 due to excessive current 3212.

[0047] Please refer to Figure 7 , Figure 7 for the photosensitive detection circuit diagram. In addition, the low-power dual-light-source lamp board further includes a photosensitive detection circuit 4, and the photosensitive detection circuit 4 includes a photosensitive resistor CDS, a first RC circuit 41, a voltage-regulator diode ZD1, a resistor R8, and a second RC circuit 42. The first RC circuit 41 is used for filtering.

[0048] The first RC circuit 41 includes a resistor R13 and a capacitor C1. One end of the resistor R18 is connected to the fifth pin of the connector J1 to receive the supply voltage, and the other end thereof is respectively connected to the capacitor C1 and the photosensitive resistor CDS, and the other end of the capacitor C1 is grounded.

[0049] One end of the voltage-regulator diode ZD1 is respectively connected to the resistor R13 and the photosensitive resistor CDS, and the other end thereof is grounded. The voltage-regulator diode ZD1 is used for voltage regulation. One end of the resistor R8 is connected to one end of the photosensitive resistor CDS, and the other end thereof is connected to the second RC circuit 42.

[0050] The second RC circuit 42 is used for filtering. The second RC circuit 42 includes a resistor R7 and a capacitor C2. The resistor R7 is connected in series to one end of the resistor R8, and the other end thereof is grounded. The capacitor C2 is connected in parallel with the resistor R7.

[0051] During actual use, the photosensitive resistor CDS changes the magnitude of its own resistance by sensing the external light. When the photosensitive resistor CDS senses that there is light in the external environment, its own resistance rapidly decreases, and a high level is provided to the control main board of the camera. At this time, the control main board drives the first light source module 2 to work; when the photosensitive resistor CDS senses that there is no light in the external environment, it is in a high-resistance state. At this time, the control main board receives a low-level signal and drives the second light source module 3 to work. Thus, by using the photosensitive detection circuit 4, automatic switching between the first light source module 2 and the second light source module 3 is realized.

[0052] The present utility model further provides a camera, which includes the above-mentioned low-power dual-light-source lamp board.

[0053] In summary, the input voltage is stabilized by the first filter circuit 211, and the buck conversion is achieved through the control chip U1 while converting the input voltage into a stable constant current source and then inputting it to the first light source module 2, so that the first light source module 2 emits light stably. It effectively prevents the first light source module 2 from overheating due to excessive current, and at the same time realizes efficient energy conversion, reduces energy loss and heat generation. At the same time, by adopting the first light-emitting component 221 with lower power and higher luminance, the first light-emitting component 22 ensures its brightness while having lower power consumption.
