Abstract

FIELD: gaseous-discharge electronic devices used as lighting lamps in industry and in the home.

SUBSTANCE: proposed lamp characterized in automatic or remote and unattended ON/OFF operation and long life of 5 000 to 10 000 hours has electronic circuit with two photodiodes, comparison circuit, microchip, and control buttons newly introduced in its electronic circuit and mechanical design. One photodiode functions to measure light flux from lamp and other one measures natural illuminance. Signals arriving from these photodiodes are passed through amplifiers to comparison device and lamp is automatically turned on or off according to preset illuminance threshold. Mode-of-operation controls in the form of push-buttons are installed on lateral end of lamp base. Lamp is provided with external control signal receiver enabling its turn-on and turn-off from remote control panel. Ability of remote control enables disposing lamp in any desired place of room or outdoors dispensing with switch or third conductor. This simplifies network design as it can dispense with switch and with conductors running to and from the latter, number of transfer contracts is reduced, wiring of lighting circuit is facilitated thereby enhancing reliability and safety of power mains. These advantages are perceptible in particular when wiring lighting circuit of summer cottage or country house plot and operating lighting devices in difficult-to-get-at locations. User-selected or automatically harnessed programs, such as annular light cycle are introduced in control microchip. Additional electronic circuit introduced in design of prior-art lamp enhances its cost by 2 or 3 dollars (USA) but essentially reduces its maintenance charges and power requirement due to eliminating the human factor.

EFFECT: reduced power requirement and maintenance charges, enlarged service life of lamp.

Description

The invention relates to electric gas-discharge electronic devices, widely used as lighting lamps both in the national economy and in everyday life for lighting residential premises, in particular.

The closest prototype of the present invention are US-discharge gas lamps developed by General Electric, an American company, where the lamp is supplied with power by means of a high-frequency pulse voltage obtained by means of an integrated electronic conversion unit powered by a mains voltage of 220 V and 50-60 Hz.

A whole series of lamps of the DEK brand of different power from 7 to 85 watts and more is known, large-scale production of lamps of this design has been mastered by large manufacturers of lighting devices in many countries of the world, including China, Germany, Hungary.

Figure 1 shows a typical design of such a lamp, and figure 2 shows a diagram of its inclusion in the mains, where

1 - lighting network

2 - gas light tube,

3 - electronic frequency converter

4 - base-case

5 - threaded part of the cap,

6 - cartridge

7 - switch.

In figure 2, the gas light tube 2 is connected to an electronic converter unit 3, one terminal of which is connected to the neutral wire of the power supply network 1, and the other output through the switch 7 is connected to the phase wire of the power supply network. The role of the switch can be performed by a relay or an electronic key of the sensor unit. The switch, as a rule, is located in a zone accessible to the user. Such a lighting switching circuit contains expensive components that, when massively used, significantly complicate the operation of the lighting sector and require the direct and constant presence of a person who does not give a full guarantee that he will forget to turn on or off the lighting devices.

Compared to incandescent lamps, gas-discharge lighting lamps have an extended service life, from 5 to 10 thousand hours, and increased light output. So, the conversion coefficient of electric energy in gas discharge lamps reaches five units. In other words, a luminous flux equivalent to five watts is given out for each watt of electricity spent compared to incandescent lamps. For example: a DEK lamp with a power consumption of 85 watts gives a luminous flux equal to 4000 lumens. Such gas-discharge lighting devices, despite its complex electronic conversion system and high cost of operation, quickly pay for themselves due to significant energy savings.

Any lighting device, whether it is an incandescent lamp or a gas discharge tube, is a passive device, and it is turned on and off manually by acting on a switch of one or another design. The rational operation of the lighting device depends entirely on the human user. In the overwhelming majority of cases, for this reason, lighting lamps often remain connected to the electric network due to the human factor, even when their need disappears with the onset of dawn. At the same time, there is an unjustified consumption of electricity.

In the main operation of lighting devices used to illuminate streets and industrial areas, this problem is not relevant, since the on and off times are set manually according to a schedule or set by a photosensitive photocell configured to a threshold level of natural light.

In individual operation of electric lighting devices, it is not always rational to complicate the lighting system with additional control devices that track the moment the lighting device is turned on and off.

The aim of the invention is to save electrical energy when using a discharge lamp as a lighting device due to its more rational use. This is achieved by the fact that when natural light falls below a set level, the lamp is automatically or remotely turned on or off. When operating a new lighting device, savings arise both due to the elimination of electrical elements (circuit breaker, wires, pads, etc.), and the exclusion of part of the installation work.

The essence of the invention lies in the fact that the electronic unit is supplemented by a receiver of an external control signal, a photocell intended for measuring illumination mounted on the side of the base / housing, and a photocell measuring the light flux emanating from the lamp, an amplifier, a comparative circuit, control buttons, a digital indicator controlling a microchip with a program of autonomous lamp operation: turning on and off according to a time, a given level of illumination, an annual light cycle, automatic programs eskogo maintain the level of illumination and interaction with remote control, connected to the frequency converter for fluorescent tube power supply and the inverter control of the microchip.

In this case, the photocell for measuring illumination, the amplifier and the comparison circuit are connected in series, the signals from the photocell measuring the light flux emanating from the lamp are fed to the comparison circuit. The signals from the comparison circuit are fed to the input of the control microchip. The control buttons are directly connected to the microchip, a digital indicator located on the side of the base / housing, and the control signal receiver with the control antenna are made using a remote control via radio or infrared.

The bodies for setting the mode of operation of the discharge lamp allow you to set the mode of operation before starting operation.

The figure 3 presents the appearance of the proposed discharge lamp, where:

8 - photocells,

9 - receiver control signal.

10 - antenna

11 - control buttons,

12 is a digital indicator.

Structurally, the gas-discharge lighting lamp, figure 3, consists of a fluorescent tube 2 mounted on the base-casing 4 with a threaded portion of the base 5, screwed into the cartridge 6 for supplying electricity to the lamp. Photocells 8 for measuring illumination, control buttons 11, digital indicator 12 and antenna 10 are installed on the side of the base / housing 4.

The figure 4 presents a functional diagram of a gas discharge lighting lamp, where:

13 - signal amplifiers of photocells,

14 is a comparison diagram,

15 - control microchip,

16 - power converter microchip,

17 - remote control.

On the functional diagram depicted in figure 4, are presented: a power frequency converter of the luminescent tubes 3 connected to the luminescent tube 2 on the one hand, on the other hand, a control microchip 15 is connected to it. Photocells 8 are connected in series to the microchip 15 for measuring illumination, photo signal amplifiers 13 and a comparison circuit 14. The control buttons 11 and the digital indicator 12 are connected to the control microchip 15. The receiver of the control signal 9 is connected to the microchip 15.

Gas discharge lamp operates as follows.

During initial installation, the lamp is screwed into the cartridge (6) to supply electricity from the mains (1). The mains voltage is supplied to the electronic frequency converter (3) of the power supply of the fluorescent tubes (2) and the power converter (16) of the control microchip (15) with additional electronic components. From the moment a gas-discharge lighting lamp is turned on in the network, photocells (8) give signals to signal amplifiers (13), proportional to their illumination. From the amplifiers, the signals are sent to the comparison circuit (14), and then to the input of the control microchip (15), where, taking into account the threshold set initially or remotely, a signal is generated to turn the lamp on or off according to a given program.

The operation mode of the gas-discharge lighting lamp can be set prior to operation using the buttons (11) and the indicator (12) located on the base / housing (4) or remotely through the control signal receiver (9). The microchip (15) contains several options (algorithms) for the lamp “behavior”: the annual light cycle or its formula, switching on and off at a given level of illumination; automatic maintenance of the level of illumination. Installation at predetermined time intervals of the lamp is carried out before its commissioning or by an external control signal. External control of a gas-discharge lighting lamp can be carried out both over the radio channel, over a standard USB port, for example, using the integrated Bluetooth module, and over the infrared channel.

The technical and economic effect of the lamp is achieved by remote control of the lamp, which allows the lamp to be hung out at any convenient place in the room or on the street, at any height, and neither a switch nor a third wire is required. This simplifies the power supply device: wires leading to the switch and from the switch to the lamp fall out, the number of transition contacts decreases, the switch is not required, the installation of lighting wiring is simplified, and thereby the reliability and safety of the power supply are increased. These advantages are especially noticeable when installing lighting in a summer cottage and in a rural area, as well as when operating lighting devices in hard-to-reach places.

The gas-discharge lighting lamp proposed by the author was manufactured at the workshop of Electronpribor OAO in St. Petersburg in April 2005, and it was tested at the workshop in industrial applications, which confirmed the specified performance characteristics based on the technical solution parameters.

An additional electronic circuit introduced in the design of the well-known gas-discharge lamp makes its manufacture more expensive by 3-5 US dollars, but significantly reduces the cost of the operation of the lighting lamp proposed by the author.
