[0020] 1 is a block diagram of a lighting device with an adaptive power adjustment function according to an embodiment of the present invention. As shown in the figure, the lighting device 1 includes a constant voltage insulation circuit 11, a DC / DC constant current power supply circuit 12, a controller 13, a load 14, a DC / DC constant voltage power supply circuit 15, a step-down circuit 16, a connector 17, a dimming signal converter 18, and an intelligent module 19A.
[0021] The constant voltage insulation circuit 11 is connected to an external power source PS. In this embodiment, the external power source PS may be a commercial power source. In another embodiment, the external power source PS may be a renewable energy power source, a generator, or other similar components. The constant voltage insulation circuit 11 insulates other circuits of the lighting device 1 from the external power source PS, reduces the voltage, and converts the input voltage of the external power source PS into a DC voltage. In one embodiment, the constant voltage insulation circuit 11 may include a constant voltage control circuit and a low voltage current limiting circuit control circuit, etc.
[0022] The DC / DC constant current power supply circuit 12 is connected to the constant voltage isolation circuit 11. In one embodiment, the DC / DC constant current power supply circuit 12 may be a buck converter, a boost converter, a buck-boost converter, or other similar components.
[0023] The controller 13 is connected to the DC / DC constant current power supply circuit 12. In one embodiment, the controller may be a microcontroller (MCU), a central processing unit (CPU), an application specific integrated circuit chip (ASIC), a field programmable logic gate array (FPGA), or other similar components.
[0024] The load 14 includes a plurality of load units. The load 14 is connected to the controller 13 and the DC / DC constant current power supply circuit 12. The plurality of load units are light emitting diode (LED) light source groups, and each light emitting diode light source group includes one or more light emitting diodes.
[0025] The DC / DC constant voltage power supply circuit 15 is connected to the constant voltage insulation circuit 11 and is also connected to the controller 13 via a step-down circuit 16. In one embodiment, the DC / DC constant voltage power supply circuit 15 may be a 12V DC / DC converter or other similar component. In one embodiment, the step-down circuit 16 may be a low-dropout linear regulator or other similar component.
[0026] The connector 17 is connected to the DC / DC constant voltage power supply circuit 15 and is connected to the controller 13 via a dimming signal converter 18. In one embodiment, the connector 17 may be an RJ11 interface. In another embodiment, the connector 17 may be a USB interface or other similar member.
[0027] Intelligent module 19A is removably connected to connector 17. In one embodiment, intelligent module 19A may be a Bluetooth controller, a WIFI controller, a ZigBee controller, an infrared sensor, a microwave sensor, or other similar components.
[0028] Of course, this embodiment is only used for illustrative purposes, and does not limit the scope of the present invention, and any equivalent modifications or variations based on the lighting device with adaptive power adjustment function of this embodiment should still fall within the protection scope of the present invention.
[0029] 2 is a first explanatory diagram of the operating state of a lighting device with an adaptive power adjustment function according to one embodiment of the present invention. As shown in the figure, the controller 13 detects the operating state of each load unit of the load 14 and generates a detection result Ds. Then, the controller 13 generates a control signal Cs based on the detection result Ds and controls the DC / DC constant current power supply circuit 12 to adjust the total output power.
[0030] The detection result Ds is the number of non-faulty load units among the multiple load units of the load 14. The controller 13 multiplies the number of non-faulty load units by the default power unit to obtain the total output power, as shown in the following formula (1). PT = L × Pu (1) Among them, PT represents the total output power, L represents the number of non-faulty load units, and Pu is the default power unit, which can be the power required by the load unit.
[0031] For example, the load 14 has five load units, and the detection result Ds indicates that the number of non-faulty load units is 3. In this case, the controller 13 calculates the total output power to be 30W (3*10W, the default power unit in this embodiment is 10W) according to formula (1).
[0032] For example, the load 14 has five load units, and the detection result Ds indicates that the number of non-faulty load units is two. In this case, the controller 13 calculates that the total output power according to formula (1) is 20 w (2*10 w). Therefore, the lighting device 1 can realize an adaptive power adjustment function by the above-mentioned mechanism.
[0033] From the above, it can be seen that in this embodiment, the lighting device 1 has an adaptive power adjustment function, and the total output power of the lighting device 1 is always matched with the non-faulty load units, so as to reduce the failure rate of these load units. Therefore, the lighting device 1 can achieve high resource utilization rate and effectively improve reliability.
[0034] In addition, in this embodiment, the lighting device 1 has an adaptive power adjustment function, so that the total output power of the lighting device 1 can always match the total output power of the non-faulty load units. The above-mentioned adaptive power adjustment function allows the lighting device 1 to operate with high efficiency. Therefore, the lighting device 1 is more energy-efficient and can keep up with future development trends.
[0035] In addition, in this embodiment, the DC / DC constant current power supply circuit 12 of the lighting device 1 is connected to the external power supply PS via the constant voltage insulation circuit 11. By combining the DC / DC constant current power supply circuit 12 and the constant voltage insulation circuit 11, the occurrence of stroboscopic phenomenon caused by the lighting device 1 can be effectively prevented, so that the lighting device 1 can provide a better usability to the user and meet the needs of practical applications.
[0036] Of course, this embodiment is only used for illustrative purposes, and does not limit the scope of the present invention, and any equivalent modifications or variations based on the lighting device with adaptive power adjustment function of this embodiment should still fall within the protection scope of the present invention.
[0037] FIG. 3 is a second explanatory diagram of the operating state of a lighting device with an adaptive power adjustment function according to an embodiment of the present invention. As shown in the figure, the intelligent module 19A can perform a human body detection function to generate a human body detection signal Ts. For example, the intelligent module 19A may be a microwave sensor. Then, the dimming signal converter 18 converts the human body detection signal Ts into a modulation signal Ms (e.g., a PWM signal). Then, the controller 13 generates a control signal Cs according to the modulation signal Ms to control the DC / DC constant current power supply circuit 12 and realize the dimming function (increase the brightness of the lighting device 1).
[0038] In another embodiment, the intelligent module 19A can also directly receive a remote control signal (for example, the intelligent module 19A can be a Bluetooth sensor). A user can operate an electronic device (such as a smartphone or a tablet computer) to send a remote control signal to the intelligent module 19A. Then, the dimming signal conversion unit 18 converts the remote control signal into a modulated signal Ms (for example, a PWM signal). Then, the controller 13 generates a control signal Cs according to the modulated signal Ms to control the DC / DC constant current power supply circuit 12 and realize the dimming function (increase or decrease the brightness of the lighting device 1).
[0039] Of course, this embodiment is only used for illustrative purposes, and does not limit the scope of the present invention, and any equivalent modifications or variations based on the lighting device with adaptive power adjustment function of this embodiment should still fall within the protection scope of the present invention.
[0040] In addition, the conventional lighting fixture does not have an adaptive power adjustment function, and the number of light sources cannot be effectively matched to the total output power. Therefore, if a conventional lighting device has multiple light sources and one of them breaks down, the other light sources are also likely to break down. As a result, the light sources of the conventional lighting device need to be replaced frequently, and high resource utilization cannot be achieved, and reliability cannot be effectively improved. In addition, the conventional lighting device does not have an adaptive power adjustment function, and therefore cannot be operated efficiently. In contrast, according to an embodiment of the present invention, the lighting device includes a constant voltage isolation circuit, a DC / DC constant current power supply circuit, a controller, and a load. The load includes a plurality of load units. The controller detects the operating state of each load unit to generate a detection result, and controls the DC / DC constant current power supply circuit according to the detection result to adjust the total output power. Therefore, the lighting device has an adaptive power adjustment function, and the total output power of the lighting device always matches the output power of the non-failed load units, and the failure rate of the load units can be reduced. Therefore, the lighting device can achieve high resource utilization and effectively improve its reliability.
[0041] Furthermore, according to an embodiment of the present invention, the lighting device is provided with an adaptive power adjustment function, which ensures that the total output power of the lighting device is always consistent with that of the non-faulty load units. The adaptive power adjustment function described above allows the lighting device to operate efficiently, so that the lighting device is more energy-efficient and can keep up with future development trends.
[0042] In addition, according to an embodiment of the present invention, the DC / DC constant current power supply circuit of the lighting device is connected to an external power supply through a constant voltage isolation circuit. The combination of the DC / DC constant current power supply circuit and the constant voltage isolation circuit can effectively prevent the lighting device from causing the strobe phenomenon, so that the lighting device can provide users with a better user experience and meet the needs of practical applications.
[0043] Furthermore, according to an embodiment of the present invention, the lighting device has a connector, which can be used to connect an intelligent module and / or a dimming circuit. The intelligent module can be a Bluetooth controller, a WIFI controller, a ZigBee controller, an infrared sensor, a microwave sensor, or other similar components. Thus, the lighting device can realize various intelligent control functions and / or intelligent dimming functions, and the lighting device can be applied to various intelligent applications. Therefore, the application of the lighting device can be further expanded, and the lighting device can be flexible in use.
[0044] Furthermore, according to the embodiment of the present invention, the lighting device is simply designed and has a specially designed adaptive power adjustment function, so that the desired effect can be achieved without significantly increasing the cost. Therefore, the lighting device can certainly effectively solve the problems of the prior art. From the above, it can be seen that the lighting device with adaptive power adjustment function according to the embodiment of the present invention can certainly achieve excellent technical effects.

[0046] The constant voltage insulation circuit 11 is connected to an external power supply PS. The DC / DC constant current power supply circuit 12 is connected to the constant voltage insulation circuit 11. The controller 13 is connected to the DC / DC constant current power supply circuit 12. The load 14 includes a plurality of load units. The load 14 is connected to the controller 13 and the DC / DC constant current power supply circuit 12. The DC / DC constant voltage power supply circuit 15 is connected to the constant voltage insulation circuit 11, and is also connected to the controller 13 via a step-down circuit 16. The connector 17 is connected to the DC / DC constant voltage power supply circuit 15, and is also connected to the controller 13 via a dimming signal converter 18. The intelligent module 19A is detachably connected to the connector 17.

In one embodiment, the dimming circuit 19B may be an analog dimming circuit, a PWM dimming circuit, a thyristor dimming circuit, or other similar dimming circuits.
[0048] The dimming circuit 19B may directly receive the dimming signal. A user can operate an electronic device (such as a smartphone or a tablet computer) to transmit the dimming signal to the dimming circuit 19B. The dimming circuit 19B then transmits the dimming signal to the dimming signal converter 18. The dimming signal converter 18 then converts the dimming signal into a modulated signal Ms (e.g., a PWM signal). The controller 13 then generates a control signal Cs in response to the modulated signal Ms to control the DC / DC constant current power supply circuit 12 and perform the dimming function (increase or decrease the brightness of the lighting device 1).

The intelligent module can be a Bluetooth controller, a WIFI controller, a ZigBee controller, an infrared sensor, a microwave sensor, or other similar components. The dimming circuit 19B can be an analog dimming circuit, a PWM dimming circuit, a thyristor dimming circuit, or other similar dimming circuits. Thus, the lighting device 1 can realize various intelligent control functions and / or intelligent dimming functions, and the lighting device 1 can be applied to various intelligent applications. Therefore, the application of the lighting device 1 can be further expanded and the use is flexible.
