Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and more particularly to a lighting control device for adjusting the brightness and color temperature of lighting fixtures. Background Art

[0002] The evolution of technology has gradually met the needs of lighting environments. For example, photoelectric light sources can be used to artificially create a suitable light environment to compensate for the lack of natural light, and can even be used as an agronomic measure to regulate the growth, development, and reproduction of agricultural crops. Alternatively, in medical environments, providing the correct light source and visibility to perform specific tasks can significantly reduce the incidence of operational errors and soothe and calm patients' emotions, allowing them to relax.

[0003] Appropriate light control typically refers to the brightness of the lighting. Traditionally, a lamp and a dimmer are connected in series to the same mains power supply. Rotating the dimmer changes the resistance of a variable resistor in the circuit, which in turn changes the trigger voltage of a connected TRIAC (Triac-Acting Actuator), causing the TRIAC to switch from an off-state to a conducting state at different trigger angles. For related information, please refer to the technical disclosures in Taiwan Utility Model Patent No. M382436, "Lighting Switch Adjustment Device."

[0004] In addition to brightness adjustment, adding ambient lighting temperature or cool light (i.e., color temperature) control can better meet the needs of most environments. Among existing technologies, for example, Taiwan Utility Model Patent No. M598380, an LED Lighting Color Temperature Adjustment Device, discloses a technique for controlling the color of a light source using a light modulator to generate a PWM signal. While the color temperature is adjustable, it is independently controlled by the light modulator. In other words, in a venue with diverse ambient lighting requirements, in addition to wiring a dimmer to adjust brightness, another light modulator must be installed to adjust color temperature, complicating wiring and increasing installation costs.

[0005] Furthermore, whether adjusting the brightness or color temperature of a lamp, it is usually a one-to-one setting. In other words, each dimmer corresponds to only one set of lamps, which is uneconomical and lacks variety. Summary of the Invention

[0006] The present invention aims to provide a more novel and advanced lighting control device for controlling several lamps, which includes a multi-stage power switch and a light control module. The multi-stage power switch is connected between the mains power and the light control module, and provides different modes of light selection and switching for the several lamps. The light control module has a rectifier, a microcontroller, a Bluetooth IC and an adjustment button; the rectifier is connected to the mains power and converts the AC mains power into a DC power supply for the microcontroller and Bluetooth IC; the microcontroller has a built-in brightness adjustment circuit, a color temperature adjustment circuit and a control program. The microcontroller is connected between the adjustment button and the Bluetooth IC. The setting of the adjustment button triggers the microcontroller to transmit a signal to the Bluetooth IC. The adjustment button is a switch that sends a signal by pressing and rotating, and is connected to the microcontroller with at least a brightness adjustment trigger circuit, a lamp status binding circuit and a color temperature adjustment trigger circuit. The microcontroller can be triggered by pressing and rotating the adjustment button. The controller adjusts different light control modes and binds or unbinds the adjusted lamps. This allows users to simultaneously adjust the brightness and color temperature of multiple lamps using a single adjustment button, simplifying wiring and directly reducing installation costs. In particular, when used with a multi-stage power switch, the previously lit lamps are bound to their settings after completing brightness and color temperature adjustments. No further adjustment is required the next time the power switch is turned on to enter the same mode. This eliminates the need for resetting or resolving difficulties to restore the original settings in special environments such as agricultural facilities or medical settings, thereby providing consistent ambient lighting in the area, which is the primary purpose of the present invention.

[0007] In addition, the Bluetooth IC described in the present invention supports the correspondence with the plurality of lamps via a wireless mesh network (BLE MESH), providing more flexible configuration and changes for the arrangement of the plurality of lamps without being limited by wiring considerations, which is another purpose of the present invention.

[0014] The present invention is a lighting control device for adjusting the brightness and color temperature of a lamp. The following description contains some typical embodiments that embody the features and advantages of the present invention. It should be understood that the present invention is capable of various variations in different forms without departing from the scope of the patent, and the descriptions and reference illustrations therein are essentially intended to describe preferred embodiments of the present invention rather than to limit the present invention.

[0015] like Figure 1 and Figure 2 As shown, the present invention mainly includes a multi-stage power switch 1 and a light control module 2 for controlling a plurality of lamps 3, wherein the multi-stage power switch 1 is connected between the mains and the light control module 2, and provides different modes of light selection and switching for the plurality of lamps 3.

[0016] The light control module 2 includes a rectifier 20, a microcontroller 21, a Bluetooth IC 22, and an adjustment button 23. The rectifier 20 is connected to the mains electricity supply, converting the AC mains electricity into DC power for the microcontroller 21 and Bluetooth IC 22. The microcontroller 21 is connected between the adjustment button 23 and the Bluetooth IC 22. The setting of the adjustment button 23 triggers the microcontroller 21 to operate and transmit signals to the Bluetooth IC 22. Preferably, a voltage regulator 24 is connected between the rectifier 20, the Bluetooth IC 22, and the microcontroller 21 to stabilize the voltage supply.

[0017] In the embodiment disclosed in the present invention, the Bluetooth IC 22 supports a wireless mesh network (BLE MESH) to correspond to the plurality of lamps 3 so that the plurality of lamps 3 can be controlled by signals transmitted by the microcontroller 21 , but the present invention is not limited thereto.

[0018] The microcontroller 21 has a built-in brightness adjustment circuit, a color temperature adjustment circuit, and a control program 21A. At least a brightness adjustment trigger circuit 210, a lamp status binding circuit 211, and a color temperature adjustment trigger circuit 212 are connected between the microcontroller 21 and the adjustment button 23. The operation of the adjustment button 23 can trigger the microcontroller 21 to adjust different light control modes. The control program 21A is a software program, but is not limited to this.

[0019] The adjustment button 23 is a switch that sends a signal by pressing and rotating, but is not limited to this; please also refer to Figure 3 The control program 21A of the microcontroller 21 is controlled by the adjustment knob 23 in the following modes:

[0020] 1. Pressing the adjustment button 23 once triggers the brightness adjustment circuit built into the microcontroller 21 via the brightness adjustment trigger circuit 210, and rotating the adjustment button 23 adjusts the brightness of the plurality of lamps 3; for example, rotating the knob left decreases the brightness, and rotating the knob right increases the brightness, but this is not limited to the above.

[0021] Second, pressing the adjustment button 23 again turns off the brightness adjustment trigger circuit 210 and triggers the color temperature adjustment circuit built into the microcontroller 21 via the color temperature adjustment trigger circuit 212. The color temperature of the plurality of lamps 3 can be adjusted by rotating the adjustment button 23. For example, rotating the knob left shifts the color toward warmer light, while rotating the knob right shifts the color toward cooler light, but this is not limited to the above.

[0022] 3. Press the adjustment button 23 N times continuously, where N≧2, to bind the lamps 3 that have been adjusted in brightness and color temperature. The next time the multi-stage power switch 1 is turned on, the brightness and color temperature settings of the lamps 3 will be maintained.

[0023] 4. Press and hold the adjustment button 23 for R seconds, where R≧2, to release the brightness and color temperature settings of the bound lamps 3.

[0024] Through the above-disclosed embodiments, it can be seen that the present invention can use a single adjustment button 23 in conjunction with the control program 21A of the microcontroller 21 to simultaneously adjust the brightness and color temperature of multiple lamps, which not only simplifies wiring but also directly reduces installation costs. In particular, the use of a multi-stage power switch 1 allows the multiple lamps 3 that have been previously lit and completed the brightness and color temperature settings to be bound together, so that no further adjustment is required the next time the multi-stage power switch 1 is turned on to enter the same mode. This can eliminate the need for resetting or resolving difficulties to restore the original settings in special environments such as agricultural facilities or medical facilities, thereby providing consistent ambient lighting in the area.

[0025] It is stated in advance that the embodiment disclosed in the present invention is only a representative of the relevant scheme and is not intended to limit the content of the invention; any equivalent applications or modifications made based on the spirit or concept of the present invention should still be covered by the scope of the patent application described later in this invention.
