Description

Multifunction device for automatic lighting in the event of a power interruption and for reliable prevention of household appliances against lightning and fluctuations in the electric current.

Technical field to which the invention relates

The present invention relates to a reliable device making it possible to illuminate a given surface and to protect household appliances against the risks associated with climatic phenomena such as storms and fluctuations in the electric current. It includes a box and a cylinder whose rotation is ensured by a reduction motor controlled by an electronic card, sensors and limit switches.

PRIOR ART

It is known from peripheral products on the market to protect devices against lightning, against fluctuations in electric current and to illuminate in the event of an interruption. However, these devices have as their main drawback a technical problem which is that of the size of a dwelling in the case of the use of several peripheral devices.

Purpose of the invention

The purpose of this multifunction invention is to solve three (3) essential problems for electricity consumers, namely to meet a need to limit the size of appliances in a home and the lower risk of electrocution. ; to integrate in a single plastic case three (3) devices for domestic use for security and lighting; and to avoid any direct contact with the devices with the hands with all the risks that entails.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 is a schematic representation of the device according to the invention, which comprises a mechanical part consisting of a jack (17), an electronic control part (3), an emergency lamp plate (7) consisting of 12 LEDs. Figure 2 is a representation of the housing.

INDUSTRIAL APPLICATION

The device according to the invention is particularly intended for all natural or legal persons who use electricity, especially those who live in all regions where they find stormy rains and poor quality in the supply of electrical energy, breakdowns of the electrical network and power outages.

Detailed Description of the Device

The device is connected to the mains via the 2-pole type plug (13) and has two output sockets (14) to supply the television set and an auxiliary output socket (15) to supply the other household appliances. It includes a coaxial cable input socket (10) distant (20 cm) from the output socket (11), an electronic card (3), a current transformer (4), a person detection module ( 5), LED lamp plate (7), Bluetooth signal detector (9), battery l

(8), a relay (2). The electronic card and the other elements are supplied from a continuous voltage (Vcc) of 5V; supplied by the 380V/16V transformer (18).

Lighting management

Once there is an interruption of the electric current, the electronic card (3) sends a voltage of 5V to the LED card (7) in order to light up a dwelling; one minute later, the electronic card causes the 12 LEDs to flash 3 times and then stabilizes them again and after 15 seconds, the LEDs go out; pressing a push button installed on the box or pressing any button on a remote control will relight the lamp for 6 hours and connecting a sun plate integrated with a battery to the jack input (19 ) increases the duration of the lighting of the emergency lamp by 12 Hours.

Management of brownout or overvoltage and power interruption

Once there is a brownout, overvoltage or power interruption, the control board (3) cancels the 5V voltage that supplies the relay (2) whenever the mains supply voltage drops. less than 110 v, greater than 250 V or zero, and the relay (2) opens its contacts thereby disconnecting the sockets (14) and (15) from the electrical network.

Cable connection management

Each time the TV set is on, the current transformer (12) sends a signal to the control board (3) and after analysis, the control board (3) sends a voltage of 5V to the actuator motor (17) in the direction of closing the NM switch, in order to establish a reliable connection between the input (10) and output (11) sockets.

Cable disconnect management

In the event that the television set is voluntarily switched off or on standby from a remote control or the master button, in the event of an interruption in the electrical current; detecting an overvoltage or a drop in voltage; circulation of a large current in the coaxial cable; prolonged absence of a person in front of the device or in front of the television set; and rain detection; the electronic plate (3) sends a voltage to the actuator motor (17) in the direction of causing the actuator to retract in order to open the NM switch or to create the separation at the input sockets (10 and 11).
