Example Embodiment

[0017] like figure 1 The principle block diagram of the control system for LED lighting for plants shown in the figure shows that the control system for lighting plants mainly consists of electronic control unit 1, CAN bus 2, central control system 3, LED light source 4, drive circuit 5, temperature sensor 6 , a light sensor 7, and a light color sensor 8. Among them, the LED driving circuit 5, the electronic control unit 1 and the evenly distributed LED light sources 4 of various colors or wavelengths constitute an illumination unit. The entire plant illumination control system has a plurality of such illumination units, which depends on the specific illumination area. The LED light sources 4 on the unit are mainly white LEDs, supplemented by red light, blue light, ultraviolet light, and infrared light. These LED light sources 4 are arrayed at certain intervals to form controllable light sources on the lamp board and synthesized according to the growth characteristics of plant...

Abstract

The invention discloses a control system for LEDs applied to plant illumination, which comprises a plurality of illumination units. Each illumination unit is provided with LED drive circuits, an electronic control unit and uniformly distributed multicolor LED light sources, wherein the LED light sources with different colors are matched with corresponding drive circuits; and the drive circuits are controlled by the electronic control unit. The plant illumination control system also comprises a far-end central master control system, and each illumination unit and the central master control system are connected and supported through CAN (Controller Area Network) buses. Independent illumination units are freely established and merged into cultivation network architecture by groups, an ideal controllable illumination system for plant cultivation is formed under the unified management of the central master control system, and the synthesized illumination is more beneficial to plant growth. An accurate warning system and an efficient heat radiating system are also beneficial to increase of the safety and the stability of the control system.

Description

technical field [0001] The invention designs a control system for illuminating plants with an LED lighting system. Background technique [0002] At present, the light sources that provide light for plants mainly include high-pressure sodium lamps and fluorescent lamps. Recently, with the technological breakthrough of high-power white LEDs and the successful application in many high-illuminance occasions, LED-based light sources have become a new trend in agricultural production to replace traditional lighting. [0003] One or several light panels are installed on each cultivation frame where plants grow. The light source of the light board can be composed of LED arrays, among which high-brightness and high-power white LEDs are the main ones, and red, blue and ultraviolet LEDs are inserted into the light board at a certain distance, and are evenly distributed in different proportions. Since sunlight is full-band for plant lighting, including red light, blue light, ultraviol...
