The first embodiment light modulating device 1 shown in Fig. 1, Fig. 2 A and Fig. 2 B can be disposed for two-wire or the electrical connection of three lines.In fig. 2, under two-wire configured in series, the conducting terminal 6 of light modulating device 1 is connected to AC primary, voltage source 7 and (linear or non-linear) light-emitting device 8 of 50/60Hz.Or Fig. 2 B depicts employing three line and configures the light modulating device, AC primary, voltage source 7 and the light-emitting device 8 that couple together.In three line configurations, dimmer arrangement 1 comprises extra conducting terminal 6', to be connected with light-emitting device 8 with AC primary, voltage source 7.
Light modulating device 1 also comprises: circuit (not shown), and described circuit is for changing the angle of flow of the voltage being applied to light-emitting device 8; Current scanning instrument 4; And digital signal processing unit 2, described digital signal processing unit is electrically coupled to described current scanning instrument and circuit.Such as, digital signal processing unit 2 can be microcomputer, and comprises analog to digital converter 2a and memory (memory store) 2b.Computer program embeds in memory in 2b, and described computer program can perform on digital signal processing unit 2, digital signal processing unit 2 to be configured to the one or more functions performed in function described herein.
When light modulating device 1 is initial and light-emitting device 8 and AC main power source 7 are connected in series (as shown in Figure 2 A and 2 B), digital signal processing unit 2 and current scanning instrument 4 are configured to be changed in response to the angle of flow of the voltage being applied to light-emitting device 8, and the current forms that light modulating device 1 is crossed in automatic convection current scans.As an example, in this embodiment, the mode changing the described angle of flow is, the angle of flow of voltage is increased to relative maximum conduction angle (being called " electric current rises and scans ") gradually from the relatively minimum angle of flow, and the described angle of flow is reduced to the relatively minimum angle of flow (being called " electric current declines and scans ") gradually from relatively maximum.The step of electric current rising scanning and electric current decline scanning represents with block 100 in flow chart 3.Digital signal processing unit 2 combines with suitable change-over circuit, is configured to automatically change the described angle of flow during sweep current form.Those skilled in the art is known and understand this type of circuit, therefore, can not discuss in detail further herein.
