Description

The utility model relates to the field of electrical engineering and is intended for automatic control of lighting for energy saving purposes.

Closest to the claimed power supply unit of the lamp, mainly with fluorescent or LED lamps, is a device of an autonomous structural module for automatic lighting control, presented in patent RU No. 2399171, IPC H05B 37/02, 09/10/2010. The known device contains a sound sensor and a microprocessor, providing two-level control of the electronic ballast of the lamp according to the original program.

The disadvantage of this device is its limited functionality, due to the presence of a one-dimensional measuring element, a sound sensor that responds only to sound, as well as the absence of an uninterruptible power supply.

The objective of the utility model is the expansion of functionality by controlling the brightness of the lamp depending on movement, the presence of a person in a given place or the level of natural light, as well as ensuring uninterrupted power.

The technical result is achieved by the fact that in an intelligent power supply unit of the lamp, mainly with fluorescent or LED lamps, consisting of a secondary power source connected to a control unit having a sensor with a microcontroller, according to this utility model, the sensor of the control unit is a matrix sensor made in as a multidimensional measuring element that integrates the functions of light, presence and motion sensors, while in the control unit den wireless interface type ZigBee connected to the microcontroller.

At the same time, an uninterruptible power supply made in the form of an ionistor connected to a secondary power source was introduced into the intelligent power supply unit of the lamp.

Thus, the technical result is achieved by creating an intelligent power supply unit for controlling the operation modes of both a single lamp and a group of lamps, providing increased energy savings by controlling the brightness of the lamp depending on movement, the presence of a person in a given place or the level of natural lighting, as well as providing remote diagnostic mode via the ZigBee wireless protocol.

With this design of the power supply unit of the lamp, its energy consumption will significantly decrease due to automatic control, the possibility of zonal separation of lighting, regulation of the level of illumination depending on the requirements of sanitary norms and rules.

In FIG. 1 shows a block diagram of the proposed intelligent power supply of the lamp.

In the diagram, the numbers indicate:

1 - lamp with fluorescent or LED lamps;

2 - source of secondary power supply;

3 - control unit

4 - microcontroller;

5 - matrix sensor;

6 - wireless interface type ZigBee;

7 - uninterruptible power supply.

The intelligent power supply unit of the lamp 1, mainly with fluorescent or LED lamps, consists of a secondary power source 2 connected to a control unit 3 having a sensor with a microcontroller 4.

The difference of the proposed intelligent power supply unit of the lamp is that the sensor of the control unit 3 is a matrix sensor 5 made in the form of a multidimensional measuring element that integrates the functions of light, presence and motion sensors, while a wireless interface of type 6 is introduced into the control unit 3 ZigBee connected to the microcontroller 4. An uninterruptible power supply 7, made in the form of an ionistor, connected to a source of 2 secondary power supply.

Intelligent power supply lamp operates as follows.

The microcontroller 4 by the signal of the matrix sensor 5 programmatically controls several brightness modes of the lamp, as well as turning it on and off.

- “Mode 1” - no person in the room - the lamp is off;

- “Mode 2” - when a person appears, the lamp turns on, and its brightness reaches a value (brightness control from 10% -100%), providing the necessary illumination on the surface, and thanks to wireless communication technology like ZigBee, it is possible to predict the trajectory of a person and, accordingly turning on the necessary fixtures;

- “Mode 3” - during human visual work, the lamp provides illumination of the working surface in accordance with sanitary standards (from 5 lux), thanks to the function of the matrix sensor 5 - measurement of the level of illumination of natural light in the room.

In “Mode 1”, the lamp is turned off in stages by reducing the brightness level, which is necessary for fluorescent lamps due to their possible burnout as a result of frequent switching on and off, for LED lamps this does not pose a threat.

In “Mode 2” the lamp does not work at full power and turns on when necessary, which significantly reduces energy costs and ensures a longer service life. The latter is explained by less degradation of the phosphor in fluorescent lamps and weaker heating of LEDs, which also increases their service life.

In "Mode 3" the function of adjusting the required level of illumination of the working area is performed by the matrix sensor 5 using the specified algorithm of the microcontroller 4 program.

The advantage of the proposed intelligent power supply for the luminaire is also the use of a wireless ZigBee 6 interface in it, which makes it possible to integrate all the luminaires used in the room. The main advantage of integrating all the lighting system devices with the ZigBee standard is the ease of installation and maintenance. Thanks to the mesh network topology and the use of special routing algorithms, the ZigBee network also provides self-healing and guaranteed signal delivery in the event of a disconnection between individual nodes, a failure of some element.

Another advantage of an intelligent power supply is the use of an energy storage capacitor - an ionistor. Its advantages are high charging and discharging speeds, long service life, small overall dimensions, high efficiency (95%). The presence of an ionistor in the circuit will provide uninterrupted power supply to the lamp and protection against failures in the power supply network, which will increase the service life of fluorescent lamps and, as a result, the efficiency of the lamp system as a whole.
