Description

Electricity-saving automatic controller for lighting lamps in public places

technical field

The utility model relates to an automatic power-saving controller for lighting lamps in public places.

Background technique

The lights in public places such as classrooms, auditoriums, meeting rooms, and corridors are often out of control, which wastes energy and shortens the life cycle of the lights. At present, such controllers generally have the following defects.

1. The precision of the light control part is low, and the error is more than a few hundred LUX.

2. The light sensor and human body sensor controller are integrated. Strictly speaking, this is a contradictory product: that is, when the light is dark to the set value, the light is turned on; after the light is turned on, the illuminance reaches the setting when it is turned off. value. At present, this contradiction can only be resolved by increasing the open and closed illuminance values (above hundreds of LUX). In addition, when someone deliberately draws the curtains during the day, the lighting will be turned on, so the power saving effect is not good.

3. Since multiple groups of human body sensors work in parallel, the probability of all failures at the same time is very low. However, there is only one illuminance standard in the entire control area, so there is only one light controller. Once a fault occurs, it will cause darkness, and it is easy to cause accidents such as trampling.

4. There is no manual device, which cannot meet special needs and needs when repairing lamps.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned existing problems and provide an energy-saving automatic controller for lighting lamps in public places.

The utility model is realized in this way: the connecting terminal of the photocontroller DJ is connected to the positive pole of the circuit, and the other connecting terminal is connected to the negative pole of the circuit; the connecting terminal of the human body sensor BH is connected to the normally closed contact DJ ₁ of the photocontroller DJ and connected with The light controller DJ is connected in parallel; the connection terminal of the relay J is connected to the normally open contact BH ₁ of the human body sensor BH, and the normally open contact BH ₁ is connected in parallel with the manual lock switch K and then connected in parallel with the light controller DJ; the lighting lamp R is connected with the relay J The normally open contact J ₁ is connected in parallel with the light controller DJ.

The utility model has the advantages that,

1. The light control setting is adjustable, and the startup and shutdown are elegant and small (10-20LXU);

2. The light sensor is separated from the main body of the controller, and the light sensor is set in an area that cannot be blocked by humans to avoid human interference.

3. Once the equipment fails at night, the lighting will be turned on automatically, which can avoid panic and stampede accidents.

4. A manual key switch is set up for special needs and lamp maintenance personnel.

Fig. 1 is a circuit diagram of the present utility model;

Detailed ways

Describe in detail below in conjunction with accompanying drawing:

The wiring terminal of the light controller DJ is connected to the positive pole of the circuit, and the other wiring terminal is connected to the negative pole of the circuit; the wiring terminal of the human body sensor BH is connected to the normally closed contact DJ ₁ of the light controller DJ, and then connected in parallel with the light controller DJ; the relay J The wiring terminal of the human body sensor BH is connected to the normally open contact BH ₁ of the human body sensor BH, and the normally open contact BH ₁ is connected in parallel with the manual lock switch K and then connected in parallel with the light controller DJ; the lighting R is connected with the normally open contact J ₁ of the relay J And then parallel with the light controller DJ.

When in use, after turning on the power,

1. When the illuminance is higher than the set value of the classroom (200LXU), auditorium (200LXU), conference room (300LXU), and corridor (75LXU), the light controller DJ is closed, the normally closed contact DJ ₁ is disconnected, and the human body is sensed The device BH and the relay J do not work, and the lighting R does not light up.

2. When the illuminance is lower than the set value of the classroom (200LXU), auditorium (200LXU), meeting room (300LXU), and corridor (75LXU), the light controller DJ is released, and the normally closed contact DJ ₁ is closed and turned on. If there are people in the room, the normally open contact BH ₁ of the human body sensor is closed and conducting, the relay J is conducting, the normally open contact of J ₁ is closed, and the lighting R is lit; when there is no one in the room, the normally open contact BH ₁ of the human body sensor is turned on disconnected, the relay normally open contact J ₁ is disconnected, and the lamp R goes out.

3. When there is a special need or for maintenance and inspection of the lamp, the manual lock switch K can be turned on, the lamp is turned on, and then turned off to return to normal.

4. When the light controller DJ fails, its normally closed contact DJ ₁ is automatically closed, and the lighting R is automatically turned on to work, avoiding panic and stampede accidents caused by darkness.

Claims (1)

1. A kind of power-saving automatic controller for lighting lamps in public places is characterized in that, the positive pole of the connecting terminal of light controller DJ connects the circuit, and the negative pole of another connecting terminal connects circuit; The connecting terminal of human sensor BH connects light controller The normally closed contact DJ ₁ of DJ is then connected in parallel with the light controller DJ; the terminal of the relay J is connected with the normally open contact BH ₁ of the human body sensor BH, and the normally open contact BH ₁ is connected in parallel with the manual lock switch K and then connected with the light controller The device DJ is connected in parallel; the lighting lamp R is connected with the normally open contact _J1 of the relay J and then connected in parallel with the light controller DJ.
