The LED lighting fixture includes a housing 1 in which a printed circuit board 2 in the form of a round at the bottom of the housing is mounted with a working surface on which a light emitting element (LED) is located.

In a preferred embodiment, the LEDs are grouped into three identical angular segments at 40 [deg.] With respect to the center of the circuit board at an angle of 80 [deg.] With respect to each other.

The primary optical system 3 may be in the form of a single mono lens mounted directly on the LED and similar to the form of the board or it may be in the form of multiple lenses in which they correspond to a number of LEDs and to which they are directly mounted.

In the following, a circular secondary optical system (multi-lens) 4 having a diameter equal to the diameter of the printed circuit board 2 is located on the same axis as the printed circuit board 2 and on the primary optical system 3 .

In a preferred embodiment, the secondary optical system consists of nine segments of lenses combined into three groups depending on the type of lens.

All segments of the secondary optical system 4 are identical and are arranged at an angle of 40 [deg.] With respect to the center of the secondary optical system 4. [

The segments of each lens group are arranged at equal intervals from each other and have the same lens degree.

One group of lenses has its own type of refraction function.

Each segment of the secondary optical system 4 corresponds to a respective LED segment on the printed circuit board 2 by shape and size.

The distance between the primary optical system 3 and the secondary optical system 4 must be minimized.

The secondary optical system 4 is fixed to the housing 1 by a sliding joint by a band for radial displacement with respect to the axis of the luminaire.

The edge of the secondary optical system 4 is provided with a position mark to determine the angle of rotation of the secondary optical system 4.

The output shaft 5 with the gear of the stepper motor is mounted in contact with the band on the outer radius of the secondary optical system 4.

The housing (1) includes an electronic unit (6) and a stepper motor provided for controlling the operation of the luminaire.

Control of the secondary optical system 4 may be performed wirelessly (using a remote control or a computer) or manually.

The secondary optical system 4 is covered by a protective screen of optically transparent material.

In yet another embodiment, the printed circuit board 2 may comprise one segment of the LED occupying half of the working surface of the printed circuit board, and the secondary optical system 4 may include one or more segments And two groups of lenses that occupy half of the surface.

In addition, the printed circuit board 2 may comprise two staggered segments of the LED occupying 2/4 of the working surface of the printed circuit board 2, and the secondary optical system 4 may be arranged in two groups of lenses And includes four segments combined in a staggered manner.

Thereafter, the printed circuit board 2 and the secondary optical system may comprise a lens group and a plurality of segments of LEDs.

The device operates as follows.

Initially, the LED segment is mounted directly on one of the lens groups of the secondary optical system 4.

When the power is turned on, the signal is transmitted on the electronic unit 6 arranged in the housing 1. [

The electronic unit 6 converts an alternating current which flows into the direct current supplied to the segmented LED on the printed circuit board 2.

All the LEDs are illuminated simultaneously and form a light flux passing through the primary optical system 3 and the secondary optical system 4, which is amplified and directed towards the illuminated surface.

When it is desired to change the illumination angle, the signal is transmitted to the computer or remote controller on the electronic unit 6 that activates the stepper motor driving the output shaft 5. [

The gear rotates the secondary optical system 4 by one step by the next position mark by the gear transmission and each segment of one lens group of the secondary optical system 4 is formed exactly on each LED segment.

In the preferred embodiment, the three segments included in one lens group are aligned with the three LED segments.

Thus, by geometrically aligning the segments of the LED segment and the secondary optical system, three types of refraction functions of the secondary optical system 4 can be implemented in combination with the LED, which allows for changes in illumination angle and LIC .

For further modification of the illumination angle, the secondary optical system 4 is displaced by the transfer of a new signal on the electronic unit 6 to the following mark.

The secondary optical system 4 can be manually displaced by rotation of the secondary optical system 4 until the secondary optical system 4 is audibly clicked at the next mark.

The lighting fixture is controlled as follows.

When the driver in the electronic unit 6 is turned on, a microcontroller control system consisting of a switch-mode power supply, a stepper motor, a microcontroller unit and a ZigBee wireless communication unit is operable.

The microcontroller is operated according to the following algorithm (the countdown starts from the voltage supply moment).

1. Microcontroller initialization (I / O port and peripheral unit settings).

2. Initialization of wireless communication unit (setting of I / O port and peripheral unit, initiation of PWM according to the last saved parameter, network search, netting).

3. Initialization of the position of the secondary optical system 4 (start of position search, installation of the last saved position). When switching the windings, the gear on the output shaft 5 of the stepper motor rotates the secondary optical system 4 by the transmission gear.

4. Wait for command by wireless protocol.

5. When a command to adjust the brightness is delivered, the PWM value is adjusted in the wireless communication unit, thereby adjusting the output current of the driver. The system enters standby mode.

6. When a command to adjust the position of the secondary optical system 4 is transmitted, the wireless communication unit transmits the command to the microcontroller via the serial interface. The microcontroller processes the command and adjusts the position of the secondary optical system 4 by switching the stepper motor winding by the microcontroller. When switching the windings, the gear on the output shaft 5 of the stepper motor rotates the secondary optical system 4 by the transmission gear. During rotation, the position marks replace the computer and thus indicate the position of the secondary optical system 4. [ When the secondary optical system 4 is arranged at a predetermined position, the stepper motor winding is switched. The final position of the secondary optical system 4 is immediately stored in the non-volatile memory of the microcontroller and stored data authentication is performed. The system enters standby mode.

The claimed lighting fixture provides a strong luminous flux sufficient to illuminate industrial and commercial sites in accordance with the possibility of arbitrary adjustment of light intensity curves as needed for instantaneous changes without disassembling the luminaire or parts thereof can do.

In addition, it is possible to manufacture a cost-effective luminaire of indoor lighting that guarantees a long service life according to the claimed configuration.
