DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 is a schematic block diagram of a light controller according to the present invention. The light controller includes a power system 1, a control unit 2, at least one traditional light control module 3, and at least one LED control module 4. The power system 1 is configured to receive and transform an external power and then output an electric signal, wherein the external power may be a high voltage power or a low voltage power. The control unit 2 is configured to generate a control signal to the power system 1 in a wired or wireless manner, wherein an electronic control signal 101 is formed by the electric signal and the control signal. Moreover, the control unit 2 may accept indications from an external system (such as a computer, a cell phone, a personal digital assistant, etc) via an interface (not shown in the Figs.) to control the control signal, wherein the control signal may be formed by a packet format. Furthermore, the content in the packet format may comprise of relative information, such as beginning data, transferring data, allocation data, luminance data, illumination data or a moving distance, that is used to control the traditional light control module 3 and the LED control module 4 in the manner of lighting order, lighting intensity, projecting angles or moving allocations, etc. In a present practical operation, the power signal is a low frequency power signal, whereas the control signal is a high frequency control signal.
Both the traditional light control module 3 and the LED control module 4 connect electrically to the power system 1 to receive instructions and a power supply according to the electronic control signal 101, which is outputted by the power system 1, wherein the electronic control signal 101 may be transferred to the traditional light control module 3 and the LED control module 4 by at least two control lines in a practical operation. Furthermore, the control lines may be applied to a practical track to form a track light design for controlling movements of lighting equipment to different locations easily.
Please refer to FIG. 1 and FIG. 2, wherein FIG. 2 is a schematic block diagram illustrating a traditional light control module according to the present invention. As shown in the figures, the traditional light control module 3 further includes a wave filter 300, a radiating unit 320, and a microprocessor 310. The wave filter 300 is configured to receive the electronic control signal 101 outputted from the power system 1 and filter the electronic control signal 101 for further outputting the electric signal 102 and the control signal 103, wherein the filtering manner in the wave filter 300 may be a manner of impedance matching. For example, it might be in a low frequency power signal loading situation (i.e. 50 or 60 Hz) in order to make the impedance from the impedance matching be relatively low, whereas it might be in a high frequency control signal non-loading situation (i.e. 115 KHz) in order to make the impedance from the impedance matching be relatively high. In this manner, the control signal 103 will not vanish when there is a disturbance from the traditional light control module 3.
The microprocessor 310 is configured to decode the control signal 103, which is filtered by the wave filter 300, which then processes original user inputting data of the control signal 103 for further controlling the operation of the radiating unit. The radiating unit 320 comprises at least one traditional illumination light 322 and a power control unit 321, wherein the power control unit 321 is configured to receive the power signal 102 for providing a required power to the traditional illumination light 322 when the traditional illumination light 322 generates light. Furthermore, the power control unit 321 may accept instructions from the microprocessor for changing the radiating effect and the operating status of the traditional illumination light 322. The traditional illumination light 322 may be an aero-discharging lamp, a tungsten filament light bulb, a haloid light bulb, or a filament light bulb, etc. Moreover, because the starters or controllers required for different bulbs and lamps are not quite the same, the power control unit 321 can change selections according to different traditional illumination lights.
The schematic wave diagram of the above-mentioned electronic control signal 101 may be shown as in FIG. 3. The wave form of the electronic control signal 101 comprises the electric signal 102 and the control signal 103, which are integrated together, so as to not only provide the required power but also control the radiating models for the traditional light control module 3 and the LED control module 4 simultaneously. Furthermore, the beginning data, transferring data, allocation data, luminance data, illumination data and moving distance which are in the above-mentioned packet format may have specific meanings. For example, the beginning data indicates a starting point of the control signal 103, the transferring data indicates the beginning of data transferal and accordingly determines if the control signal 103 is a valid signal or not. The allocation data indicates which light source can be controlled by the control signal 103, the luminance data is used to control the luminance of each light source, and the illumination data and moving distance are used to control illumination angles and required moving distances of the light sources, respectively.
As described above, the light controller of the present invention mainly controls the LED control modules 4 but is also capable of mixing general traditional light control modules 3, and, furthermore, the control signal 3 is not disturbed because of the mixture. Based on the above features, the present invention not only controls the light sources in order presentations, lighting intensity and random changes, but also increases the overall flexibility and adaptive fields of the light controller.
It should be emphasized that the above-described embodiments are merely examples of possible implementations. Many variations and modifications may be made to the above-described embodiments without departing from the principles of the present disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
