[0016] In a refinement of the invention, the illuminance conversion parameter is a ratio value between the second illuminance value and the first illuminance value. Effect of the Invention

[0017] Based on the above, a real-time constant illumination adjustment system and method according to an embodiment of the present invention has one or more advantages. (1) The real-time constant illuminance adjustment system of the present invention includes a lighting device and an illuminance adjustment device. The lighting device includes a first constant illuminance controller, a light source connected to the first constant illuminance controller, and a first illuminance detector. The light source emits a light beam. The first illuminance detector is installed at a first position and detects the illuminance at the first position to generate a first illuminance value. The illuminance adjustment device includes a second constant illuminance controller and a second illuminance detector installed at a second position and connected to each other. The second illuminance detector detects the illuminance at the second position to generate a second illuminance value, and the second constant illuminance controller transmits the second illuminance value to the first constant illuminance controller. The first constant illuminance controller calculates illuminance conversion parameters for the first and second positions based on the first and second illuminance values.

Therefore, the real-time constant illuminance adjustment system can meet the needs of practical applications. (2) The real-time constant illuminance adjustment system of the present invention has a special illuminance conversion mechanism. When the ambient light changes, the real-time constant illuminance adjustment system can still maintain the illuminance of the lighting device at the target illuminance value through the above illuminance conversion mechanism, thereby achieving the effect of real-time constant illuminance. Therefore, the application of the real-time constant illuminance adjustment system is broadened and the use is more flexible. (3) The illuminance adjusting device of the real-time constant illuminance adjusting system of the present invention can be removed or turned off after executing the initial setting program and completing the calculation of the illuminance conversion parameters, so that the illuminance adjusting device does not need to continue detecting the illuminance of the second position, thereby effectively reducing the energy consumption of the real-time constant illuminance adjusting system and making the real-time constant illuminance adjusting system conform to the requirements of environmental protection and future development trends. (4) The first constant illuminance controller of the lighting device of the real-time constant illuminance adjustment system of the present invention is directly powered by the power supply of the lighting device and does not require a separate battery, which further reduces the overall cost of the real-time constant illuminance adjustment system and makes the maintenance of the real-time constant illuminance adjustment system more convenient. Thus, the reliability of the real-time constant illuminance adjustment system can be greatly improved.

[0021] 1 is a block diagram of a real-time constant illuminance adjustment system according to a first embodiment of the present invention. As shown in the figure, the real-time constant illuminance adjustment system 1 includes a lighting device 11 and an illuminance adjustment device 12.

[0022] The lighting device 11 includes a first constant illuminance controller 111 , a first communication circuit 112 , a first illuminance detector 113 and a light source 114 .

[0023] The light source 114 is connected to the first constant illuminance controller 111 and emits a light beam. In this embodiment, the light source 114 may be a light emitting diode (LED). In another embodiment, the light source 114 may be a light emitting diode array or other similar components.

[0024] The first illuminance detector 113 is connected to the first constant illuminance controller 111. In this embodiment, the first illuminance detector 113 may be a light sensor. In another embodiment, the first illuminance detector 113 may be a sensor that detects another illuminance.

[0025] The first communication circuit 112 is connected to the first constant illuminance controller 111. In this embodiment, the first communication circuit 112 may be a Bluetooth (registered trademark) module. In other embodiments, the first communication circuit 112 may be a Zigbee module, a WiFi module, or other similar components.

[0026] The first constant illuminance controller 111 may be a CPU, a microcontroller (MCU), an application specific integrated circuit chip (ASIC), a field programmable gate array (FPGA), or other similar components.

[0027] The illuminance adjusting device 12 is installed at a second position, and includes a second illuminance constant controller 121 , a second communication circuit 122 and a second illuminance detector 123 .

[0028] The second communication circuit 122 is connected to the second constant illuminance controller 121. In this embodiment, the second communication circuit 122 may be a Bluetooth module. In other embodiments, the second communication circuit 122 may be a Zigbee module, a WiFi module, or other similar components.

[0029] The second illuminance detector 123 is connected to the second constant illuminance controller 121. In this embodiment, the second illuminance detector 123 may be a light sensor. In other embodiments, the second illuminance detector 123 may be a sensor that can be used for other illuminance detection.

[0030] The second constant illuminance controller 121 may be a CPU, a microcontroller, an application specific integrated circuit chip, a field programmable gate array or other similar component.

[0031] 2 is a first explanatory diagram of the operation state of the real-time constant illuminance adjustment system according to the first embodiment of the present invention. As shown in the figure, the first illuminance detector 113 of the lighting device 11 is installed at a first position and detects the illuminance at the first position to generate a first illuminance value L1. In this embodiment, the first position may be located on the outer surface of the globe of the lighting device 11. In other embodiments, the first position may be located on the inner surface of the globe of the lighting device 11.

[0032] The second illuminance detector 123 of the illuminance adjustment device 12 detects the illuminance at the second position (i.e., the target position) and generates a second illuminance value L2. The distance between the second position and the light source 114 is greater than the distance between the first position and the light source 114. The second constant illuminance controller 121 of the illuminance adjustment device 12 transmits the second illuminance value L2 to the first constant illuminance controller 111 of the lighting device 11. The first constant illuminance controller 111 of the lighting device 11 calculates illuminance conversion parameters for the first and second positions based on the first illuminance value L1 and the second illuminance value L2. The illuminance conversion parameter is a ratio value between the second illuminance value L2 and the first illuminance value L1, as shown in the following formula (1). L2 = X × L1 (1) Here, X represents an illuminance conversion parameter. Equation (2) can be obtained from equation (1) as follows: X=L1 / L2 (2)

[0033] A user directly sets one predetermined illuminance value as the second illuminance value L2 via an electronic device (such as a smartphone, a tablet PC, or a notebook computer). Then, the first constant illuminance controller 111 of the lighting device 11 can gradually decrease the brightness of the light source 114 of the lighting device 11 until the illuminance at the second position detected by the second illuminance detector 123 of the illuminance adjustment device 12 reaches the second illuminance value L2. Finally, the first constant illuminance controller 111 of the lighting device 11 calculates illuminance conversion parameters for the first and second positions based on the first and second illuminance values ​​L1 and L2. The illuminance conversion parameters can represent the illuminance relationship between the first and second positions.

[0034] After obtaining the illuminance conversion parameters, the real-time constant illuminance adjustment system 1 can implement a special illuminance conversion mechanism: a user sets a target illuminance value through an electronic device, and the first constant illuminance controller 111 of the lighting device 11 gradually adjusts the brightness of the light source 114 of the lighting device 11, and the first constant illuminance controller 111 of the lighting device 11 adjusts the brightness of the light source 114 of the lighting device 11 when the current illuminance value of the second position is equal to the target illuminance value.

[0035] Through the above-mentioned illuminance conversion mechanism, the first constant illuminance controller 111 of the lighting device 11 estimates the current illuminance value of the second position based on the illuminance conversion parameters and the illuminance detection value of the first position, and gradually adjusts the brightness of the light source 114 of the lighting device 11. Then, when the current illuminance value of the second position is equal to the target illuminance value, the first constant illuminance controller 111 of the lighting device 11 can stop adjusting the brightness of the light source 114 of the lighting device 11. The above-mentioned illuminance conversion mechanism can estimate the current illuminance value of the second position to constantly maintain the illuminance of the lighting device 11 at the target illuminance value, thereby achieving the effect of real-time constant illuminance. Therefore, the real-time constant illuminance adjustment system 1 can meet the requirements of practical applications.

[0036] The illuminance adjusting device 12 can be removed or turned off after executing the initial setting program and completing the calculation of the illuminance conversion parameters, so that the illuminance adjusting device 12 does not need to continue to detect the illuminance at the second position. Therefore, the energy consumption of the real-time constant illuminance adjusting system 1 can be effectively reduced, and the real-time constant illuminance adjusting system 1 can be further adapted to the requirements of environmental protection and future development trends.

[0037] In addition, the first constant illuminance controller 111 of the lighting device 11 of the real-time constant illuminance adjustment system 1 can be directly powered by the power supply of the lighting device 11 and does not require a separate battery. This can further reduce the overall cost of the real-time constant illuminance adjustment system 1 and make the maintenance of the real-time constant illuminance adjustment system 1 more convenient. In this way, the reliability of the real-time constant illuminance adjustment system 1 can be significantly improved.

[0038] 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 alterations made based on the real-time constant illuminance adjustment system of this embodiment should still fall within the scope of protection of the present invention.

[0039] 3 is a second explanatory diagram of the operation state of the real-time constant illuminance adjustment system according to the first embodiment of the present invention. As shown in the figure, when the ambient light EL changes (the brightness of the ambient light EL increases or decreases), the first constant illuminance controller 111 of the lighting device 11 adjusts the brightness of the light source 114 of the lighting device 11, and calculates the current illuminance value of the second position based on the illuminance detection value of the first illuminance detector 113 of the lighting device 11 and the illuminance conversion parameter. The first constant illuminance controller 111 of the lighting device 11 stops adjusting the brightness of the light source 114 of the lighting device 11 when the current illuminance value of the second position is equal to the target illuminance value.

[0040] For example, when the brightness of the ambient light EL increases, the first constant illuminance controller 111 of the lighting device 11 reduces the brightness of the light source of the lighting device 11, and calculates a current illuminance value of the second position based on the illuminance detection value of the first illuminance detector 113 of the lighting device 11 and the illuminance conversion parameter. The first constant illuminance controller 111 of the lighting device 11 stops reducing the brightness of the light source 114 of the lighting device 11 when the current illuminance value of the second position is equal to the target illuminance value.

[0041] Conversely, when the brightness of the ambient light EL decreases, the first constant illuminance controller 111 of the lighting device 11 increases the brightness of the light source 114 of the lighting device 11, and calculates a current illuminance value of the second position based on the illuminance detection value of the first illuminance detector 113 of the lighting device 11 and the illuminance conversion parameter. The first constant illuminance controller 111 of the lighting device 11 stops increasing the brightness of the light source 114 of the lighting device 11 when the current illuminance value of the second position is equal to the target illuminance value.

[0042] As can be seen from the above, when the ambient light changes, the real-time constant illuminance adjustment system 1 can still maintain the illuminance of the lighting device 11 at a target illuminance value through the above illuminance conversion mechanism, thereby achieving the effect of real-time constant illuminance. Therefore, the application of the real-time constant illuminance adjustment system 1 can be made more extensive and more flexible in use.

[0043] 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 alterations made based on the real-time constant illuminance adjustment system of this embodiment should still fall within the scope of protection of the present invention.

[0044] 4 is a structural diagram of a lighting device of a real-time constant illuminance adjustment system according to a first embodiment of the present invention. As shown in the figure, the lighting device 11 may further include a globe 115 and a lighting fixture body 116 connected to each other. The first constant illuminance controller 111, the first communication circuit 112 and the light source 114 may be installed in the globe 115 and located between the globe 115 and the lighting fixture body 116. The first illuminance detector 113 may be installed on the outer surface (first position) of the globe 115. In another embodiment, the first position may be the inner surface of the globe 115.

[0045] 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 alterations made based on the real-time constant illuminance adjustment system of this embodiment should still fall within the scope of protection of the present invention.

[0046] In addition, the illumination adjustment function of the conventional illumination system is too complicated, and cannot effectively achieve the effect of constant illumination, and cannot meet the needs of practical application. In contrast, according to the first embodiment of the present invention, the constant illumination adjustment system of the present invention includes an illumination device and an illumination adjustment device. The illumination device includes a first constant illumination controller, a light source and a first illumination detector connected to the first constant illumination controller. The light source emits light. The first illumination detector is installed at a first position and detects the illumination at the first position to generate a first illumination value. The illumination adjustment device includes a second constant illumination controller and a second illumination detector installed at a second position and connected to each other. The second illumination detector detects the illumination at the second position to generate a second illumination value, and the second constant illumination controller transmits the second illumination value to the first constant illumination controller. The first constant illumination controller calculates illumination conversion parameters for the first and second positions based on the first and second illumination values. The first constant illuminance controller receives the target illuminance value, gradually adjusts the brightness of the light source, and calculates the current illuminance value of the second position according to the illuminance detection value of the first illuminance detector and the illuminance conversion parameters. The first constant illuminance controller adjusts the brightness of the light source when the current illuminance value of the second position is equal to the target illuminance value. Through the above illuminance conversion mechanism, the real-time constant illuminance adjustment system can constantly maintain the illuminance of the lighting device at the target illuminance value, achieving the effect of real-time constant illuminance. Therefore, the real-time constant illuminance adjustment system can meet the needs of practical applications.

[0047] In addition, the real-time constant illuminance adjustment system of the present invention has a special illuminance conversion mechanism. When the ambient light changes, the real-time constant illuminance adjustment system can still maintain the illuminance of the lighting device at a target illuminance value through the illuminance conversion mechanism, thereby achieving the effect of real-time constant illuminance, making the application of the real-time constant illuminance adjustment system more extensive and more flexible in use.

[0048] In addition, the illuminance adjusting device of the real-time constant illuminance adjusting system of the present invention can be removed or turned off after executing the initial setting program and completing the calculation of the illuminance conversion parameters, so that the illuminance adjusting device does not need to continue detecting the illuminance of the second position, thus effectively reducing the energy consumption of the real-time constant illuminance adjusting system and making the real-time constant illuminance adjusting system meet the requirements of environmental protection and future development trends.

[0049] In addition, the first constant illuminance controller of the lighting device in the real-time constant illuminance adjustment system of the present invention is directly powered by the power supply of the lighting device and does not require a separate battery, which further reduces the overall cost of the real-time constant illuminance adjustment system and makes the maintenance of the real-time constant illuminance adjustment system more convenient. Thus, the reliability of the real-time constant illuminance adjustment system can be greatly improved.

[0050] Furthermore, the design of the real-time constant illuminance adjustment system of the present invention is simple, so that the desired effect can be achieved without significantly increasing the cost. Therefore, the real-time constant illuminance adjustment system can achieve higher practicability and meet the requirements of different applications. From the above, it can be seen that the real-time constant illuminance adjustment system of the first embodiment of the present invention can indeed achieve excellent technical results.

Step S52: Detect the illuminance at the second position by a second illuminance detector of the illuminance adjustment device to generate a second illuminance value. Step S53: Send the second illuminance value to the first constant illuminance controller of the lighting device via the second constant illuminance controller of the illuminance adjustment device. Step S54: Calculate illuminance conversion parameters for the first and second positions according to the first and second illuminance values ​​by a first illuminance constant controller of the lighting device. Step S55: Receive a target illuminance value through a first constant illuminance controller of the lighting device, and gradually adjust the brightness of the light source of the lighting device. Step S56: A first constant illuminance controller of the lighting device calculates a current illuminance value at the second position according to the illuminance detection value of the first illuminance detector and the illuminance conversion parameter. Step S57: When the current illuminance value at the second position is equal to the target illuminance value through the first illuminance constant controller of the lighting device, the adjustment of the brightness of the light source is stopped.

[0052] 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 alterations made based on the real-time constant illuminance adjustment method of this embodiment should still fall within the scope of protection of the present invention.

[0053] Although the steps of the methods described herein are shown and described in a particular order, the order of operations of each method may be changed, some steps may be performed in reverse order or simultaneously with other steps, and in alternative embodiments, different steps may be performed intermittently and / or alternatingly.

As shown in the figure, the real-time constant illuminance adjusting method according to the present embodiment further includes the following steps: Step S61: gradually adjust the brightness of the light source of the lighting device when the ambient light changes through a first constant illuminance controller of the lighting device. Step S62: A first constant illuminance controller of the lighting device calculates a current illuminance value at the second position based on the illuminance detection value of the first illuminance detector and the illuminance conversion parameters. Step S63: When the current illuminance value at the second position is equal to the target illuminance value via the first illuminance constant controller of the lighting device, the adjustment of the brightness of the light source is stopped.

[0055] 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 alterations made based on the real-time constant illuminance adjustment method of this embodiment should still fall within the scope of protection of the present invention.

[0056] Although the steps of the methods described herein are shown and described in a particular order, the order of operations of each method may be changed, some steps may be performed in reverse order or simultaneously with other steps, and in alternative embodiments, different steps may be performed intermittently and / or alternatingly.

[0057] In summary, based on the first and second embodiments of the present invention, the constant illuminance adjustment system of the present invention includes an illumination device and an illuminance adjustment device. The illumination device includes a first constant illuminance controller, a light source and a first illuminance detector connected to the first constant illuminance controller. The light source emits a light beam. The first illuminance detector is installed at a first position and detects the illuminance at the first position to generate a first illuminance value. The illuminance adjustment device includes a second constant illuminance controller and a second illuminance detector installed at a second position and connected to each other. The second illuminance detector detects the illuminance at the second position to generate a second illuminance value, and the second constant illuminance controller transmits the second illuminance value to the first constant illuminance controller. The first constant illuminance controller calculates illuminance conversion parameters for the first and second positions based on the first and second illuminance values. The first constant illuminance controller receives the target illuminance value, gradually adjusts the brightness of the light source, and calculates the current illuminance value of the second position according to the illuminance detection value of the first illuminance detector and the illuminance conversion parameters. The first constant illuminance controller adjusts the brightness of the light source when the current illuminance value of the second position is equal to the target illuminance value. Through the above illuminance conversion mechanism, the real-time constant illuminance adjustment system can constantly maintain the illuminance of the lighting device at the target illuminance value, achieving the effect of real-time constant illuminance. Therefore, the real-time constant illuminance adjustment system can meet the needs of practical applications.

[0058] In addition, the real-time constant illuminance adjustment system of the present invention has a special illuminance conversion mechanism. When the ambient light changes, the real-time constant illuminance adjustment system can still maintain the illuminance of the lighting device at a target illuminance value through the illuminance conversion mechanism, thereby achieving the effect of real-time constant illuminance, making the application of the real-time constant illuminance adjustment system more extensive and more flexible in use.

[0059] In addition, the illuminance adjusting device of the real-time constant illuminance adjusting system of the present invention can be removed or turned off after executing the initial setting program and completing the calculation of the illuminance conversion parameters, so that the illuminance adjusting device does not need to continue detecting the illuminance of the second position, thus effectively reducing the energy consumption of the real-time constant illuminance adjusting system and making the real-time constant illuminance adjusting system meet the requirements of environmental protection and future development trends.

[0060] In addition, the first constant illuminance controller of the lighting device in the real-time constant illuminance adjustment system of the present invention is directly powered by the power supply of the lighting device and does not require a separate battery, which further reduces the overall cost of the real-time constant illuminance adjustment system and makes the maintenance of the real-time constant illuminance adjustment system more convenient.
