Description

An intelligent energy-saving lighting controller

Technical field:

The utility model belongs to the field of electronic technology, and is a controller for controlling the brightness of a lighting fixture.

Background technique:

At present, the brightness control of the public lighting facilities of buildings is generally controlled manually. In order to save electric energy, some lights are turned off when the natural light is strong. The energy saving effect is not obvious, it is inconvenient to operate, and the use effect is not good.

Invention content:

The technical problem to be solved by the utility model is to disclose a lighting controller that controls public lighting facilities through intelligent means, thereby effectively saving energy.

Lighting control systems work by dimming or turning lights off or on as required. The main control power supply is composed of alternating current. This current flows in one direction along the transmission cable, and then turns to the other direction. The speed is 50 or 60 circuits per second, if the frequency unit is Hertz (HZ). The frequency value is 50HZ or 60HZ. This frequency depends on the grid system of the country or region where it is located.

If we look at the waveform of alternating current, we see that it has a stretched S shape on one side. If a line is drawn in the middle of the waveform, this is the so-called zero crossing point. Dimming is achieved by turning off the dead-state module or triac, and then turning it on again after passing the zero crossing point for a period of time. The longer this period is, the less power will pass through the module or triac and into the light, and the dimmer the light will be. The module or triac switches at a rate of 100 times per second each time the crossing point of the main current (commonly known as half phase) is reached.

Save up to 98% of unused energy when dimming lights. Since the perception of light intensity by the human eye is non-linear, it is possible to reduce the brightness level of the light by more than 10% in advance, and the human eye cannot perceive the brightness change at this time. In this way, 10% of electric energy can be saved. If you reduce the dimming brightness level by 50%, you can save about 40% of power. Smart dimmers fade lights to pre-set levels. This is especially important when turning on the lights for the first time. Grading the lamp to a preset level is also known as "soft start" and can greatly extend the life of the lamp. Using a dimming level of 10% can extend the life of the lamp by more than two times, and using a dimming level of 50% can prolong the service life of about 20 times. At the same time, the system also has a voltage stabilizing function, which can protect the lamp from being damaged by the peak voltage in the main circuit.

The solution of the utility model to solve the technical problem is to adopt the drive circuit, the signal acquisition circuit and the execution circuit to form an intelligent energy-saving lighting controller.

When MCU1 gets the opening instruction, pin 20 of MCU1 outputs a high level, relay J1 pulls in, its normally open contacts K1 and K2 close, and the full-wave rectifier bridge T4 supplies power to the voltage-controlled oscillator TLC5551 and the drive module TLP250 to make it After receiving power, the lighting lamp is turned on through the power output module IGBT.

Enter the motor M1 to work, change the resistance value of the potentiometer W1, adjust the oscillation frequency of the voltage-controlled oscillator TLC5551, and control the brightness of the lighting.

Compared with common public lighting facilities, the utility model can save electric energy by 60-70%.
