Description

technical field

The utility model relates to the technical field of LED lighting, in particular to a central control system of an LED intelligent lighting device which can be controlled by wireless equipment through wireless communication.

Background technique

Light-Emitting Diode (LED) is a light-emitting device that can directly convert electrical energy into visible light. As a new generation of lighting source after compact fluorescent lamps (ordinary energy-saving lamps), compared with ordinary energy-saving lamps, LED light sources have many advantages such as small size, low power consumption, long service life, and strong controllability. However, in the field of LED lighting applications, most companies tend to focus on the energy-saving characteristics of LEDs, while ignoring their controllability.

In fact, with the rapid development and mutual penetration of computer technology, communication technology, automatic control technology, bus technology, signal detection technology and microelectronic technology, lighting control technology has made great progress.

The combination of the two, LED intelligent lighting came into being.

Due to the limitations of traditional lighting standards, the control and management that can be realized by the connection device of the existing LED lighting device are relatively simple in form and relatively simple in function. For example, thyristor dimming can realize the brightness adjustment of lighting devices within a certain range of variation, and further management, such as time, brightness, scene and other presets, is not yet possible. In particular, when the number of LED intelligent lighting devices reaches a certain scale, its automatic control becomes particularly important.

In addition, with the popularity of wireless devices, users tend to use the same device rather than multiple different devices to control electrical appliances. However, if a wireless communication device is used for user control on each LED lighting device, the cost is high.

In order to achieve LED intelligent lighting, especially the centralized management of LED intelligent lighting devices using existing wireless devices, a new central control system is required in this technical field.
