Description

Technical Field

[0001] The present invention relates to a lighting device, particularly a lighting device with an adaptive power adjustment function.

Background Art

[0002] With the improvement of environmental awareness, energy conservation and environmental protection have become common goals around the world. The power consumption of lighting equipment accounts for about 20% of the total power consumption, and reducing the power consumption of lighting equipment is an important means of energy conservation. To achieve this goal, various energy-saving lighting devices have emerged, but these conventional lighting devices still have many drawbacks that need to be improved.

[0003] For example, conventional lighting fixtures do not have an adaptive power adjustment function and cannot effectively match the number of light sources with the total output power. Therefore, if there are multiple light sources in a conventional lighting device and one of the light sources fails, the other light sources are also likely to fail. As a result, the light sources of conventional lighting devices often need to be replaced, and high resource utilization cannot be achieved, nor can the reliability be effectively improved.

[0004] In addition, because conventional lighting devices do not have an adaptive power adjustment function, they cannot operate efficiently.

[0021] The constant voltage insulation circuit 11 is connected to an external power supply PS. In this embodiment, the external power supply PS may be a commercial power supply. In another embodiment, the external power supply PS may be a renewable energy power supply, a generator, or other similar components. The constant voltage insulation circuit 11 insulates and steps down other circuits of the lighting device 1 from the external power supply PS, and converts the input voltage of the external power supply PS into a DC voltage. In one embodiment, the constant voltage insulation circuit 11 may include a constant voltage control circuit, a low voltage current limiting circuit control circuit, and the like.

[0022] [[ID=第十五]] 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 isolation circuit 11 and is 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 components. In one embodiment, the step-down circuit 16 may be a low-dropout regulator or other similar components.

[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 components.

[0027] The intelligent module 19A is detachably connected to the connector 17. In one embodiment, the intelligent module 19A may be a Bluetooth® controller, a Wi-Fi controller, a ZigBee controller, an infrared sensor, a microwave sensor, or other similar component.

[0028] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and any equivalent modifications or changes made based on the lighting device with adaptive power adjustment function of this embodiment should still be within the scope of protection of the present invention.

[0029] Figure 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 part 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 above is the number of load units that are not faulty among the multiple load units of load 14. The controller 13 calculates the total output power by multiplying the number of load units that are not faulty by the default power units, as shown in equation (1) below. PT = L × Pu (1) Of these, PT represents the total output power, L represents the number of load units that are not faulty, and Pu can be the power required by the load unit, with the default power unit being the power required by the load unit.

[0031] For example, load 14 has five load units, and the detection result Ds indicates that the number of load units that are not faulty is 3. In this case, controller 13 calculates that the total output power is 30W (3 * 10W, the default power unit in this embodiment is 10W) ​​according to equation (1).

[0032] For example, load 14 has five load units, and detection result Ds indicates that the number of non-faulting load units is two. In this case, controller 13 calculates that the total output power is 20W (2*10W) according to equation (1). Therefore, lighting device 1 can realize an adaptive power adjustment function by the mechanism described above.

[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 that of the load units that are not malfunctioning, thereby reducing the failure rate of these load units. Therefore, the lighting device 1 can achieve a high resource utilization rate and effectively improve reliability.

[0034] Furthermore, in this embodiment, the lighting device 1 is equipped with an adaptive power adjustment function, which allows the total output power of the lighting device 1 to always match the total output power of the load units that are not malfunctioning. Due to the adaptive power adjustment function described above, the lighting device 1 can operate with high efficiency. Therefore, the lighting device 1 is more energy-efficient and can keep pace with future development trends.

[0035] Furthermore, in this embodiment, the DC / DC constant current power supply circuit 12 of the lighting device 1 is connected to an external power supply PS via a constant voltage isolation circuit 11. By combining the DC / DC constant current power supply circuit 12 and the constant voltage isolation circuit 11, the occurrence of strobe phenomena by the lighting device 1 can be effectively prevented, allowing the lighting device 1 to provide a better user experience and meet the needs of actual applications.

[0036] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and any equivalent modifications or changes made based on the lighting device with adaptive power adjustment function of this embodiment should still be within the scope of protection of the present invention.

[0037] Figure 3 is a second 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 intelligent module 19A can perform a human body detection function and generate a human body detection signal Ts. For example, the intelligent module 19A may be a microwave sensor. The dimming signal converter 18 converts the human body detection signal Ts into a modulated signal Ms (e.g., a PWM signal). The controller 13 then 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 (increasing the brightness of the lighting device 1).

[0038] In another embodiment, the intelligent module 19A can also directly receive remote control signals (for example, the intelligent module 19A may be a Bluetooth® sensor). The user can operate an electronic device (smartphone, tablet computer, etc.) to send remote control signals to the intelligent module 19A. The dimming signal conversion unit 18 then converts the remote control signal into a modulated signal Ms (e.g., a PWM signal). The controller 13 then 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 (increasing or decreasing the brightness of the lighting device 1).

[0039] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and any equivalent modifications or changes made based on the lighting device with adaptive power adjustment function of this embodiment should still be within the scope of protection of the present invention.

[0040] Conventional lighting fixtures lack adaptive power adjustment capabilities and cannot effectively match the number of light sources to the total output power. Therefore, if a conventional lighting device has multiple light sources and one of them fails, the other light sources are also more likely to fail. As a result, the light sources in conventional lighting devices frequently need to be replaced, preventing the achievement of high resource utilization rates and effectively improving reliability. Furthermore, conventional lighting devices lack adaptive power adjustment capabilities, making efficient operation impossible. In contrast, according to embodiments 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 multiple load units. The controller detects the operating state of each load unit, generates 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, ensuring that the total output power of the lighting device always matches the output power of the load units that are not malfunctioning, thereby reducing the failure rate of the load units. Consequently, the lighting device can achieve high resource utilization rates and effectively improve its reliability.

[0041] Furthermore, according to embodiments of the present invention, the lighting device is equipped with an adaptive power adjustment function that always matches the total output power of the lighting device with that of a non-faulty load unit. Due to the aforementioned adaptive power adjustment function, the lighting device can operate efficiently. Therefore, the lighting device is more energy-efficient and can adapt to future development trends.

[0042] Furthermore, according to embodiments of the present invention, the DC / DC constant current power supply circuit of the lighting device is connected to an external power supply via a constant voltage isolation circuit. By combining the DC / DC constant current power supply circuit and the constant voltage isolation circuit, the occurrence of strobe phenomena by the lighting device can be effectively prevented, the lighting device can provide a better user experience, and can meet the needs of actual applications.

[0043] Furthermore, according to embodiments of the present invention, the lighting device has a connector that can be used to connect an intelligent module and / or a dimming circuit. The intelligent module can be a Bluetooth® controller, a Wi-Fi controller, a ZigBee controller, an infrared sensor, a microwave sensor, or other similar component. 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 applications of the lighting device can be further broadened, and it also offers flexibility in use.

[0044] Furthermore, according to the embodiments of the present invention, the design of the lighting device is simple, and because it is equipped with a specially designed adaptive power adjustment function, the desired effect can be obtained without significantly increasing costs. Therefore, the lighting device can certainly effectively solve the problems of the conventional technology. From the above, it can be seen that the lighting device equipped with an adaptive power adjustment function according to the embodiments of the present invention can certainly achieve excellent technical effects.

[0045] Figure 4 is a block diagram of a lighting device with adaptive power adjustment function according to another embodiment of the present invention. As shown in the figure, the lighting device 1 includes a constant voltage isolation 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.

[0046] The constant voltage isolation 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 isolation circuit 11. The controller 13 is connected to the DC / DC constant current power supply circuit 12. The load 14 includes multiple 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 isolation circuit 11 and also to the controller 13 via the step-down circuit 16. The connector 17 is connected to the DC / DC constant voltage power supply circuit 15 and also to the controller 13 via the dimming signal converter 18. The intelligent module 19A is detachably connected to the connector 17.

[0047] Since the components described above are the same as those in the previously described embodiment, a detailed explanation is omitted here. A difference from the previously described embodiment is that the lighting device 1 of this embodiment further includes a dimming circuit 19B. The dimming circuit 19B 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 another similar dimming circuit.

[0048] The dimming circuit 19B may receive the dimming signal directly. The user can transmit a dimming signal to the dimming circuit 19B by operating an electronic device (smartphone, tablet computer, etc.). 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 according to the modulated signal Ms to control the DC / DC constant current power supply circuit 12 and execute the dimming function (increasing or decreasing the brightness of the lighting device 1).

[0049] As can be seen from the above, the lighting device 1 has a connector 17 that can be used to connect the intelligent module 19A and the dimming circuit 19B.

The dimming circuit 19B may be an analog dimming circuit, a PWM dimming circuit, a thyristor dimming circuit, or other similar dimming circuit. Therefore, 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. Thus, the applications of the lighting device 1 can be further broadened, and it also has flexibility in use.

[0050] Similarly, in this embodiment, the lighting device 1 is equipped with an adaptive power adjustment function, which allows the total output power of the lighting device 1 to always match the total output power of the load units that are not faulty. Due to the adaptive power adjustment function described above, the lighting device 1 can operate with high efficiency.
