Description

Power adjustment controller and method thereof

The present invention relates to a power adjustment controller and method thereof, and more particularly to a power adjustment controller and method for applying various dimmers to all lamps.

Dimmers are used in a wide variety of applications. Wherever power energy needs to be controlled, dimmers can be used to achieve the goals, such as controlling the speed of the motor, controlling the temperature of the soldering iron, and so on. The most widely used place for dimmers is to control the brightness of the lamps. By controlling the brightness of the lamps, the effect of beautifying and creating an atmosphere can be achieved, which is one of the indispensable applications in modern decoration design. Please refer to the first figure, which is a schematic diagram of a conventional dimmer applied to a luminaire. An AC power source 10' (e.g., a 110 volt AC power source) is electrically coupled to a dimmer 20' to provide AC power to the dimmer 20'. The dimmer 20' is electrically coupled to a luminaire 40' for supplying power to drive the luminaire 40'. However, conventional dimmers have a variety of trigger circuit designs, such as the use of a controlled rectifier (SCR) or a triac (Triac), which can cause a manufacturer's lamps to use another The shortcomings of the manufacturer's dimmers for dimming may cause damage to the lamps or dimmers, and even cause sparks and fires and other unfortunate events.

It is therefore an object of the present invention to provide a power adjustment controller that improves the shortcomings of conventional dimmers that cannot be applied to all luminaires due to their different trigger circuit designs.

It is still another object of the present invention to provide a power adjustment control method to improve the disadvantages of conventional dimmers that cannot be applied to all luminaires due to their different trigger circuit designs.

To achieve the above object, the power adjustment controller of the present invention is applied between a dimmer and a load, and the dimmer outputs a dimmer signal to the power adjustment controller. The power adjustment controller comprises: an integration unit, a peak detection unit, a database unit and a power supply unit. The integrating unit and the peak detecting unit receive the dimmer signal and separately perform integral and peak detection to output an energy integration signal and a peak detection signal. The database unit receives the energy integration signal and the peak detection signal and processes the same to output a power control signal to the power supply unit. The power supply unit cooperates with a feedback signal from one of the loads to drive the load with the output power.

To achieve the above object, the power adjustment control method of the present invention is applied between a dimmer and a load, and the dimmer outputs a dimmer signal. The power adjustment control method includes: integrating the dimmer signal to generate an energy integration signal; performing peak detection on the dimmer signal to generate a peak detection signal; and the energy integration signal and the peak detection The signal is compared in a database unit to generate a power control signal; and a power supply unit is controlled by the power control signal and a feedback signal from the load to drive the load to the output power.

Please refer to the second figure, which is the power adjustment controller application of the present invention. The block diagram is intended to illustrate the application of the power adjustment controller of the present invention. An AC power source 10 (e.g., a 110 volt AC power source) is electrically coupled to a dimmer 20 to provide AC power to the dimmer 20. The dimmer 20 is electrically coupled to a power adjustment controller 30 and outputs a dimmer signal to the power adjustment controller 30. The dimmer signal will be different due to the different trigger circuit design of the dimmer 20, such as using a controlled rectifier (SCR) or a triac (Triac). The power adjustment controller 30 is electrically coupled to a load 40 and converts the dimmer signal into a drive power source suitable for the load 40 to drive the load 40. Taking the load 40 as a luminaire as an example, the disadvantage that the dimmer 20 cannot be applied to all the luminaires due to different trigger circuit designs can be improved.

Please refer to the third figure, which is a block diagram of the power adjustment controller of the present invention, and please refer to the second figure at the same time. The power adjustment controller 30 of the present invention comprises: an integration unit 302, a peak detection unit 304, a database unit 306, and a power supply unit 308. The database unit 306 is electrically connected to the integration unit 302, the peak detection unit 304, and the power supply unit 308. The integrating unit 302 is configured to receive the dimmer signal and integrate to output an energy integration signal. The peak detecting unit 304 is configured to receive the dimmer signal and perform peak detection to output a peak detecting signal. The database unit 306 is configured to receive the energy integration signal and the peak detection signal and process the same to output a power control signal. The power supply unit 308 is configured to receive the power control signal, and output a power source to drive the load 40 after receiving and processing a signal from the load 40.

Please refer to the fourth figure, which is the power adjustment control method of the present invention. Please also refer to the second and third figures. First, step S2 integrates the dimmer signal to generate the energy integration signal. At the same time, step S4 performs peak detection on the dimmer signal to generate the peak detection signal. Then, in step S6, the energy integration signal and the peak detection signal are compared in the database unit 306 to generate the power control signal. Finally, step S8 controls the power supply unit 308 by the power control signal and the feedback signal from the load 40 to drive the load 40 with an output power.

In addition, in the above embodiments, the load 40 may be a light fixture, for example, more than one light emitting diode, but is not limited to a light fixture or a light emitting diode, and any application suitable for the light dimmer 20, For example, the motor, the soldering iron, and the like are all within the scope of implementation; the power supply unit 308 can be a switching power supply; the database unit 306 is a memory, and the internal storage corresponds to the energy integral. The signal and the power control signal that should be output by the peak detection signal, as shown in the following table.

In summary, it is known that the present invention has industrial applicability, novelty and advancement, and the structure of the present invention has not been seen in similar products and public use, and fully complies with the requirements of the invention patent application, and is filed according to the patent law.
