Description

Multifunctional Lighting Circuit System

technical field

The invention relates to the technical field of lighting, in particular to a multifunctional lighting circuit system.

Background technique

When a fire breaks out indoors, the indoor air is limited, and the burning items are incompletely burned due to insufficient air. When incompletely burned, a large amount of dense smoke will be generated, and due to the limitation of indoor space, the dense smoke will not be released in time. Smoke and low visibility.

When a fire breaks out indoors, due to the low visibility caused by the thick smoke, the fire extinguishers cannot accurately find the fire source, delaying the fire extinguishing time, and the fire is not extinguished in time, which leads to the rapid expansion of the fire, which makes it difficult to extinguish the fire; It is easy to panic and lose track of the way. If you escape to the vicinity of the fire source and then find the escape route again, the escape time will be delayed and the chance of escape will be reduced.

Existing lighting systems for fire emergency can only provide emergency lighting for the environment, which is of little help in finding the location of the fire source. Firefighters or escapees often delay fire fighting and rescue because they do not know the location of the fire source. The best time to escape, so there is an urgent need for a lighting system that can indicate the location of the fire source at the fire scene.

Contents of the invention

The object of the present invention is to provide a multifunctional lighting circuit system capable of indicating the direction of the fire source when a fire occurs.

The multifunctional lighting circuit system in this solution includes a bowl-shaped lampshade for reflecting light and a lamp holder for fixing the lampshade, the lamp holder is arranged on the wall, and a rotatable LED lamp is arranged inside the lampshade board, the LED light board is provided with a hollow frame, a bowl-shaped outer cover for reflecting and refracting light is provided under the lamp cover, and a first suspender and a second suspender for supporting the outer cover are provided. The first suspender is hinged to the outer cover, the first suspender is fixed on the lamp holder, the second suspender is magnetically matched with the outer cover, the second suspender is hinged on the lamp holder, and the second suspender can be Opened by the rotating LED light board;

Also includes:

The motor is located in the lampshade, and the transmission shaft of the motor is connected with the LED lamp board to drive the LED lamp board to rotate;

A plurality of infrared temperature sensors are evenly distributed in the frame of the LED light board for sensing the temperature of the environment;

The microcontroller is used for judging according to the signal sent by the infrared temperature sensor. When the temperature exceeds the threshold, it is judged that a fire has occurred, and the microcontroller sends a signal to control the LED lamp board to detect the increase of the ambient temperature. The position rotation control signal is also used to issue a flashing signal to control the flashing of the LED light board according to the signal of the infrared temperature sensor;

The motor controller is used to control the rotation of the motor according to the control signal of the microcontroller, so that the LED light board rotates in the direction specified by the control signal of the microcontroller;

The on-off module is used to control the LED light board to flash according to the flashing signal of the microcontroller;

Power module for powering the microcontroller.

The working principle and beneficial effects of this scheme are that when the fire is not fired, the LED light board emits light for lighting, and the light irradiated on the inner wall of the lampshade is re-ejected after reflection, and the light of the LED light board and its reflected light are irradiated on the outer cover. The outer cover reflects and refracts the light and its reflected light again, forming floodlight around the lampshade and the outer cover, increasing the range of light irradiation.

When any infrared temperature sensor senses a certain temperature and the microcontroller judges that the temperature exceeds the threshold, the microcontroller sends a control signal to the motor controller to let the motor controller control the rotation of the motor, and the motor drives the LED light board to detect the temperature. The position of the changing infrared temperature sensor moves, because the infrared temperature sensors are evenly distributed in the frame of the LED light board to form a circle, and the direction where the infrared temperature sensor that detects the temperature change is located is the direction of the fire source.

Make the light irradiated by the LED light board aim at the direction of the fire source, indicate the exact position of the fire source for the escapees or fire extinguishers, prevent the escapees from running to the fire source, and reduce the time for the escapers to delay their escape due to wrong directions. Let the fire extinguishers accurately find the location of the fire source, and reduce the delay in extinguishing the fire because the fire source cannot be found.

When a fire broke out, because the rotation of the LED light board pushes away the second suspender, which destroys the magnetic cooperation between the second suspender and the outer cover, the outer cover is pushed away and no longer reflects and refracts the light, so that the LED light board The light can be shot directly downward, which is convenient to use. After the outer cover leaves the second suspender, it is supported by the first suspender, so it will not fall and hit people.

While the microcontroller sends a control signal to the motor controller, when the microcontroller sends a flashing signal to the on-off module, the on-off module controls the LED light board to flash according to the flashing signal, and the flashing light has a warning function to remind people around in danger.

Before a fire occurs, because the lampshade is bowl-shaped, the inner wall of the lampshade is used as a reflective surface, and the reflective surface is not a regular plane. The light is emitted from many different directions through the reflected light on the inner wall of the lampshade; at the same time, the bowl-shaped outer cover is reflecting or refracting the light. When the light is reflected or refracted, the medium surface is not a regular plane. After the light is reflected or refracted by the outer cover, the light can be emitted from many different directions, so that the lighting range is larger.

In the event of a fire, during the rotation of the LED light board to the infrared temperature sensor that detects the temperature, that is, to the position of the fire source, the LED light board touches the outer cover, and the light is no longer reflected or refracted by the outer cover. Higher, let the light shine directly in the direction of the fire source, and more clearly indicate the location of the fire source.

Note: The left side refers to the left-hand side facing the drawing, and the right side refers to the right-hand side facing the drawing.

Further, the on-off module includes a triode switch.

The transistor switch is easy to obtain, the principle is simple, the use is more convenient, and the price is cheap.

Further, the right end of the LED lamp board is in contact with the right side wall inside the lampshade, and the left sidewall and the right sidewall outside the lampshade are respectively connected with a first wire and a second wire, and the first wire connects to the The hinge point on the left side of the LED light board extends into the frame of the LED light board.

When the LED lamp board is in contact with the right side wall in the lampshade, the first wire communicates with the second wire. The way of connecting and disconnecting the first wire and the second wire is simpler.

Further, it also includes a relay whose output circuit is connected to the mains power supply line, and the first wire and the second wire are connected to the input circuit of the relay.

When the LED light board is disengaged from the right side wall inside the lampshade, the first wire and the second wire are disconnected to disconnect the input circuit of the relay, and at the same time the output circuit of the relay is also disconnected, disconnecting the mains power supply and protecting the mains circuit.

Further, the LED light board is also provided with an independent power supply.

When the LED light board is disengaged from the right side wall in the lampshade, the power supply is disconnected, and the independent power supply allows the LED light board to continue to maintain brightness, indicating the source of the fire.

Further, a nozzle is provided at the contact between the right side of the LED lamp board and the right side wall inside the lampshade, and the irritating gas can be emitted from the nozzle.

When the LED light board is disengaged from the right side wall in the lampshade, the nozzle is exposed. Since the nozzle is not blocked by the LED light board, the irritating gas in the nozzle emits to remind people around that a fire has occurred.

Further, the LED lamp board is arranged on the transmission shaft of the motor inclined toward the lampshade side, and the included angle between the LED lamp board and the horizontal direction is 60°.

When the LED light board is rotating, open the second suspender so that the second suspender is willing to leave the outer cover, destroying the magnetic cooperation relationship between the second suspender and the outer cover, so that the outer cover no longer reflects and refracts the light, ensuring that the LED lights The board can push away the second suspender, and the LED light board can be tilted to point to the direction of the fire source.
