Originally segments LEDs installed directly over one of the lens groups of the secondary optical system 4. At power-up signal to the electronic unit 6, located in the housing 1. The electronic unit 6 converts incoming AC to DC, which goes to the St. todiode, segmented located on the circuit Board 2. All the LEDs are illuminated at the same time, creating a luminous flux, which passes through the primary optical system 3 and the secondary optical system 4, is amplified and is directed towards the illuminated surface.

When you need to change the angle of the light signal using the remote or the computer enters the electronic unit 6, which runs the stepper motors that drive the output shaft 5. Through the transmission gear gear produces rotation of the secondary optical system 4 one step to the next position of the label and each segment of one group of lenses of the secondary optical system 4 rises exactly over each segment LEDs.

In a preferred variant embodiment is a combination of three segments that are part of one lens group, with three segments LEDs.

Thus, geometrically aligning the segments of the secondary optical system 4 strictly with the segments of the LEDs, you can get three types of functions of refraction of the secondary optical system 4, which allows in combination with LEDs to change the lighting angle and the CMP.

For further change lighting angle move the secondary optical system 4 to the next label by submitting a new signal in the electronic unit 6.

The displacement W is the hexadecimal format of the optical system 4 can be done manually by turning the secondary optical system 4 until you hear, what is happening in the moment of movement of the secondary optical system 4 to the next label.

2. The initialization unit of the wireless communication channel (port settings I/o, peripherals, start PWM with the last saved values, network search, inclusion in the network).

3. Initializing the position of the secondary optical system 4 (finding the starting position, install the last saved position). When switching winding gear on the output shaft 5 of the stepper motor through the transmission gear produces rotation of the secondary optical system 4.

4. Waiting for the wireless Protocol.

5. When passing commands to adjust the brightness block of the wireless communication channel is adjusted PWM value, thereby adjusting the output current of the driver is. The system enters standby mode new data.

6. When passing commands to adjust the position of the secondary optical system 4 unit wireless communication channel transmits the command via the serial interface to the microcontroller. The microcontroller will process the command and adjusts the position of the secondary optical system 4 by switching the microcontroller of the windings of the stepper motor. When switching winding gear on the output shaft 5 of the stepper motor through the transmission gear produces rotation of the secondary optical system 4. During the rotation position of the label commute the computer, thereby indicating the position of the secondary optical system 4. When placing the secondary optical system 4 at a predetermined position of the switching of the windings of the stepper motor. The last position of the secondary optical system 4 immediately saved in non-volatile memory of the microcontroller, and then reviewing it on the correctness of the stored data.
