Description of the Invention: [Technical Field] The present invention relates to an intelligent light-emitting diode lighting system, and more particularly to an illumination system capable of sensing a light state in an environment and automatically adjusting a light output condition. [Prior Art] Due to low power consumption, small size and long service life, LED components are widely used in household appliances, backlights for liquid crystal displays, graphic display screens, and third car lights. And other applications. In recent years, light-emitting diode materials such as aluminum gallium indium phosphide (AlGalnP) and aluminum gallium indium nitride (A1GaInN) have been successfully developed, so that conventional incandescent light bulbs can be replaced with light-emitting diode elements in many applications. At present, the light-emitting diode lighting device converts the indoor alternating current into a low-voltage direct current by using a transformer, and the light-emitting diode element or the light-emitting diode module is driven by the current to emit light. However, to control the brightness of the lighting device, a variable resistor is needed to adjust the current level, that is, the rotation of the variable resistor must be manually operated to set the brightness. Since the source of light in the environment is not all from the lighting device, it is often affected by the change of outdoor lighting, that is, the light transmitted from the window in the morning, noon and dusk will change the indoor and clear state. Therefore, if you want to maintain a certain brightness or fixed lighting in the room, you need to constantly adjust the manpower. It is not only very inconvenient to use, but also often adjusts to the high-bright turn-out mode to save energy. On the other hand, 'current lighting devices can still use the light generated by the LEDs in the LED module to mix the output light of different color temperatures, 5 1310891 lines, so it can be adjusted according to the situation or season. Color temperature, for example, is illuminated by warm light in cold winters. However, since the mixing and blending of red, blue and green light is not a simple linear relationship, it is not a simple task to adjust only by manpower. In summary, there is a need in the market for an illumination system that automatically senses light in the environment and automatically adjusts the light output conditions to improve the various shortcomings of the conventional illumination devices described above.
