Description

Smart light source control circuit and intelligent light source control method

The present invention relates to a light source device, and more particularly to a smart light source control circuit and a smart light source control method.

Lamps play a very important role in human life. The application of the luminaire can be seen in buildings, vehicles or decorations. For humans, luminaires are not only a tool for providing illumination, but currently common lighting devices include incandescent lamps, fluorescent lamps, and light-emitting diode (LED) lamps. Incandescent lamps energize the tungsten wire to produce high thermal illumination for illumination. Fluorescent lamps emit electrons by applying a high voltage to the electrodes, causing electrons to strike atoms of the mercury vapor, causing ionization and excitation. When the mercury vapor atoms return from the excited state to the original state, electromagnetic waves are emitted. Therefore, by using a variety of different fluorescent substances to absorb the electromagnetic waves and convert them into visible light, the fluorescent lamps can emit various colors. The light-emitting diode emits light-emitting diodes by a combination of electron holes under appropriate forward bias. This is because the electrons fall back from the high energy state to the low energy state and combine with the hole to release the energy in the form of light.

When the wireless communication interface receives the control command packet of the handheld electronic device, the microprocessor controls the driving circuit to drive the light emitting unit according to the control command packet. When the sensing circuit generates the sensing signal, the microprocessor controls the driving circuit to drive the lighting unit according to the sensing signal.

The microprocessor 124 is coupled to the driving circuit 121, the wireless communication interface 122, the sensing circuit 123, and the feedback circuit 125. The wireless communication interface 122 receives the control command packet S1 from the handheld electronic device 13. The sensing circuit 123 senses the light fixture 11 to generate a sensing signal S2. For example, the sensing circuit 123 senses whether the luminaire 11 is tapped or rotated to generate the sensing signal S2.

First, as shown in step 201, the microprocessor 124 determines that the wireless communication interface 122 receives the control command packet S1 or the sensing circuit 123 generates the sensing signal S2. When the wireless communication interface 122 receives the control command packet S1, step 22 is performed. As shown in step 22, the microprocessor 124 controls the drive circuit 125 to drive the light emitting unit 111 in accordance with the control command packet S1.

Second embodiment

Please refer to FIG. 1 and FIG. 3 at the same time. FIG. 3 is a flow chart showing a calibration procedure. The aforementioned microprocessor 124 is more capable of executing a calibration procedure to determine a System correction value. The calibration procedure can be turned on in three ways. The first way is that the user executes the application by the handheld electronic device 13 to issue a notification correction packet. The wireless communication interface 122 receives the notification correction packet via wireless communication. The microprocessor 124 executes the calibration procedure in accordance with the notification correction packet. The second way is that the microprocessor 124 automatically performs the calibration procedure at regular intervals. The third way is that after the failure or replacement of the illumination unit 111 of the luminaire 11, the microprocessor 124 automatically executes the calibration procedure after learning that the feedback signal S3 is out of range multiple times.

The aforementioned calibration procedure includes the following steps: First, as shown in step 31, the microprocessor 124 determines whether a calibration procedure needs to be performed. If no calibration procedure is required, go to step 35. Conversely, if a calibration procedure is to be performed, step 32 is performed. As shown in step 32, the feedback circuit 125 provides the feedback signal S3 of the illumination unit 111 to the microprocessor 124. Then, as shown in step 33, the microprocessor 124 repeatedly adjusts the output power Po of the driving circuit 121 according to the feedback signal S3 until the power variation of the output power Po is less than a threshold value. Following the step 34, when the amount of power change is less than the threshold of change, the microprocessor 124 records the output power Po as a system correction value and stores the system correction value to the storage device. Then, as shown in step 35, the microprocessor 124 controls the drive circuit 121 to drive the light emitting unit 111 in accordance with the system correction value.

Further, the heat generated by the light-emitting unit 11 will change the resistance value of the system load, so the microprocessor 124 needs to repeatedly adjust the output power Po of the drive circuit 121 when performing the calibration procedure. The output power Po is repeatedly adjusted until after a period of time, the interior of the lamp 11 will gradually reach thermal equilibrium, and the output power Po will also tend to be a system correction value. The microprocessor 124 determines whether the output power Po of the drive circuit 121 exceeds the rated power of the drive circuit 121 based on the feedback signal S3. When the output power Po exceeds the rated power, the microprocessor 124 controls the drive circuit 121 to decrease the output power Po. Conversely, when the output power Po does not exceed the rated power, the microprocessor 124 controls the drive circuit 121 to increase the output power Po.
