Description

The invention relates to electric lighting and electronic lighting, and in particular to methods and control systems for two or more light modules of an electric lamp, while possible brightness modes (luminous flux values) of an electric lamp are formed by a different number of simultaneously switched on light modules.

A device and method of its operation are known according to the application WO2008 / 034242, (selected as a prototype of the method and the electric lamp). The light emitting element control system comprises arrays of light emitting elements and can control the inclusion in response to a control signal based on a joint relationship between the arrays, said joint relationship comprising a predetermined relationship stored in said control module or an adaptive relationship determined from one or more performance characteristics rulers. Possible switching schemes and possible combinations of included light emitting elements are described. In this case, the task of ensuring and supporting the operating mode based on the selected relationship is solved.

This system does not provide options for the relationship between the lines, determined on the basis of dynamically changing in time the external parameters (signals) of the environment and / or the characteristics of the environment themselves and do not set themselves the goal of a possible solution to the problem of increasing the life of light modules of the electric lamp, and consequently of the electric lamp itself, due to the equalization of the life of all its light modules and, accordingly, the life of the equipment, tvovannogo to provide power and control modules for various lighting modes brightness (luminous flux) created lighting units during operation electrical lamps.

The technical task is to increase the life of the light modules of the electric lamp and equipment involved in providing power, and control the light modules by equalizing the operating time of all light modules at different brightness modes (luminous flux values) created by them during the operation of the electric lamp.

The technical result is achieved in the method of operation of the electric lamp, consisting of at least two light modules, in which the required level of illumination is achieved by simultaneously turning on part or all of the light modules, while turning on the part, the light modules are selected, aligning the operating time of all light modules when the lamp is operating. A part of the light modules is simultaneously turned on with a cyclic shift over a time interval. The operating time for each light module is determined, for their part to be switched on simultaneously, the light modules with the smallest operating time are selected. As a light module, a set of light sources with a single mode of operation at the current time is used. The level of illumination is chosen when recording changes in the external environment and / or when registering the target object.

The technical result is achieved in an electric lamp consisting of two or more light modules, which are used as sets of light sources with a single operating mode at the current time (in a set), made with the possibility of providing the required level of illumination, including a control system for light modules, made with the ability to equalize the operating time of all light modules when operating an electric lamp. The control system of the light modules is configured to simultaneously turn on part of the light modules with a cyclic shift through the time interval. The control system for the light modules is configured to determine the operating time for each light module and select a portion of the light modules with the lowest operating time for their simultaneous inclusion. The control system includes means for recording changes in the external environment and / or means for registering the target.

The invention is illustrated by drawings.

Figure 1 - circuit electric lamp;

Figure 2 - the work of electric lamps;

Figure 3 - the joint operation of the light modules.

An electric lamp is two or more light modules and a control system (Fig. 1). A light module is a ruler (a set of light sources) consisting of at least one element of a light source, while the operating mode for all light sources of a light module in a set is the same current time.

The equipment can be installed on the supports of light sources (Fig. 2), which are the main nodes of a wireless network, and includes the following subsystems: control, two-way communication, object monitoring in the zone, power supply and control of light modules, emergency operation and temperature control and equipment operability, and also may additionally include subsystems: measurements of natural light, dust control (contamination) of the lampshade and autonomous power supply of electric lights nick. The main one is a wireless network node, which has one (or more) luminaire (light source) mounted on a support, and equipment that provides: the required illumination in the zone of this node, monitoring the object in the zone of the node and two-way information exchange over the air in the corresponding zone transmit-receive both between neighboring (working) nodes, and between the control center (hereinafter referred to as the control center) according to the principle from node to node.

Functionally, the structure of the main node includes the following subsystems. Control subsystem - manages all subsystems, linking them into a single complex, and contains its own microcontroller that processes subprograms. The management subsystem performs the following main functions:

- collecting and processing signals from other subsystems and making decisions on their basis for adjusting the parameters (characteristics) of the light source (s) (in stand-alone mode);

- equalization of operating time: light modules, equipment of the power subsystem and control of light modules;

- adjustment of parameters (characteristics) of the light source (s) by command from a neighboring node or from the control center when operating in a single network mode;

- the formation of control commands for neighboring network nodes;

- monitoring the performance of all subsystems, except for the emergency mode subsystem, including a diagnostic test with a complete check of all operating modes on command from the control center and generating a report for the control center;

- transfer to the control center information about the state and malfunctions of the node.

The two-way communication subsystem provides communication with the nearest efficient network nodes (capable of receiving and transmitting signals from / to another node (s)), contains a wireless communication module and its own microcontroller that processes subroutines. The two-way communication subsystem performs the following functions:

- registration in the network and periodic transmission and reception of registration packets so that the node that does not respond to requests is excluded from the packet transmission chain — formatted blocks of information transmitted over a computer network.

- transmission of packets with control commands to neighboring nodes and reception of similar packets;

- the formation and transmission of packets with information for the control center, which will go along the chain from one node to another;

- reception and transmission of transit packets — packets for the control center and from the control center for all nodes through which they pass, except for the source node that formed the packet and the node for which the packet is intended.

- integrity control of received packets and a request for retransmission in case of errors.

The object monitoring subsystem provides detection of incoming, outgoing and located in the area of the node objects, which require artificial lighting. Includes one or more sensors to detect an object.

The power supply and control subsystem of the light modules, at the command of the control subsystem, provides the required (flexibly reconfigurable) speeds of both rise and fall of the brightness of the light modules of the lamp (s), as well as turning on or off the required number of light modules.

The subsystem for monitoring the temperature and efficiency of the equipment includes feedback sensors that measure the brightness of the glow, dust (contamination) of the surface of the lampshade (subsystem for controlling dustiness of contamination) of the lampshade), as well as the temperature and current consumption of the equipment and, in case of exceeding the norm, provides automatic shutdown of light modules. Sensor signals are analyzed by the control subsystem.

The emergency operation subsystem monitors the operability of the control subsystem and, in the event of its failure, puts the lamp (s) in the state of the maximum possible intensity of brightness or completely turns off the lamp (s).

The autonomous power supply subsystem of the electric lamp ensures the operation of the equipment in an autonomous mode.

The subsystem for measuring natural illumination measures the level of natural illumination, on the basis of which the brightness of the lamp (s) is adjusted.

The method is implemented as follows.

Possible brightness modes (luminous flux values) are formed by a different number of simultaneously switched on light modules, i.e. the electric lamp is not just turned on, but has several gradations of brightness (luminous flux), implemented due to the number of simultaneously switched on light modules. In this case, the required brightness mode (luminous flux), in addition to the maximum, is selected by switching on those light modules whose operating time was the smallest (or equal) compared to the operating time of other light modules.

Situations when different brightness modes (luminous flux values) of an electric luminaire are used arise both in industry and in everyday life, as a rule, different modes are used either to save electricity or to provide the necessary comfort in light. For example: an electric lamp operates in 2 modes: emergency lighting, - not at full brightness in the absence of an object in the illuminated area and working lighting, - at full brightness, in the case of the presence of an object in the illuminated zone; the electric lamp works taking into account natural illumination, while the number of included light modules changes depending on the intensity of natural (natural) illumination during the day.

An increase in the service life of light modules in an electric lamp is achieved due to the cyclic shift of the included light modules by the control subsystem (Fig. 3) at a predetermined time interval, which leads to equalization of the operating time of all light modules during operation of the electric lamp, while the value of the time interval can vary and set in the control subsystem depending on the operating conditions and / or the intended use of the electric lamp. Providing the necessary brightness mode (luminous flux) is determined by turning on the required number of light modules using the control subsystem based on processing of current parameters and environmental characteristics.

Otherwise, an increase in the life of the light modules in the electric lamp is achieved based on the counting by the control subsystem of the operating time for each light module of the electric lamp. At the same time, the required brightness mode (luminous flux value) is ensured at a given time interval by the control subsystem based on the processing of current parameters and environmental characteristics and the control subsystem switches on those light modules whose calculated operating time is the shortest (if suddenly the operating time of the light modules coincided, any module is selected), which leads to equalization of the operating time of all light modules during operation of the electric lamp.
