Connect sensor LED lamp display intelligence

Introduction: LED lighting to replace the traditional incandescent lamp has become a reality, LED lighting industry in recent years has been a great development. According to the electronic industry in July 9th released a research report, some people worry that LED lighting will enter the off-season, but the third quarter, professional analysts believe that LED lighting will continue to grow in the third quarter, LED lighting speed upward trend has not changed, still watching from the sales level at 20%, is only a temporary seasonal reasons that growth slowed, 4Q growth will rebound quickly. In addition to the recent rise of the concept of intelligent lighting, LED lights let more favored.

The basic principle of the intelligent lighting system is a user of the terminal module (including mobile terminal) under the command, transmits the signal to the control center software through the electronic induction, with controller circuit voltage and current amplitude, to regulate the light intensity and color etc.. The whole system can be divided into intelligent lighting control system, digital addressable LED driver, lamps and light source products. A typical intelligent lighting system is to complete the transfer from the input to the output. The user can through a variety of input methods (control software, sensors, smart socket) to transfer the data to the main controller (Gateway), followed by the main controller through the ZigBee protocol to achieve output (LED lamp, LED panel light control). LED lighting fixtures and traditional lighting the biggest difference, LED lighting is a complete electronic products, while the traditional lighting is only an electrical product. Therefore, LED lamps can be easily associated with various types of sensors, so as to achieve light control, infrared control and other automatic control functions. Such as LED street lamp automatic switch, with a photosensitive sensor can be simple to achieve; community night walkways and garden lighting, you can use infrared sensors to collect human activity information, automatic opening and closing lighting fixtures.

Automatic control of LED lighting switch

The sensor device as a signal acquisition and electromechanical conversion, electromechanical technologies are quite mature, MEMS technology in recent years and sensor technology to miniaturization, intelligent, multi-functional, low cost strides forward. The sensitive sensors, infrared sensors and other types of and can be composed of an LED intelligent lighting control system, sensor to collect various physical signal into electrical signals through the integrated circuit of AD converter, MCU converter, DA signals collected for intelligent processing, so as to control LED lighting on and off. Human beings can set various control requirements on the MCU to control the switching time, brightness, color and color of the LED lamp, so as to achieve the goal of saving energy and saving energy. The current integrated circuit manufacturing technology has been able to AD, DA, MCU integrated in a 5X5mm or smaller package, installed in the lamp is neither occupied area and very convenient.

Photosensitive sensor and LED lamp combination

Wind power LED street lamp is a kind of highly intelligent and unmanned road lighting. It is very important to use wind energy and sunlight to generate electricity. The photosensitive sensor is an ideal electronic sensor which can control the automatic switching of the circuit due to the change of illumination at dawn and dusk. Photosensitive sensor photosensitive plate is very sensitive to light and dark brightness. Photosensitive sensor, according to the weather, time and area of automatic control of LED lighting fixtures. Reduce power consumption by reducing its output power during the bright day, compared with the use of fluorescent lights, the store area of 200m2 convenience stores can reduce the power consumption by 53%. Life is about 5 million 100 thousand hours. In general, LED lighting lamp life of 40 thousand hours; the color of light also can be used RGB colorful way to store light more colorful, more active atmosphere; compared with the original blue phosphor supporting the use of $LED, supporting the use of red, green and blue phosphor LED color of purple high.
