Embodiment Construction

[0023] figure 1 It is a schematic block diagram of the intelligent LED lighting system of the present invention. The lighting system 10 includes an LED module 14 , a sensing module 13 , a control circuit 12 and a driving circuit 11 . The sensing module 13 can automatically detect the relevant parameters of light in the lighting environment, such as: brightness, chromaticity or color temperature, etc., and can automatically detect the temperature in the environment; it can include a luminance meter, a colorimeter, a color difference meter or a thermometer An equivalent sensing circuit, instead of a single one, senses the respective light components of red (R), green (G), and blue (B) in the mixed light. Moreover, the control circuit 12 can adjust the driving current outputted by the drive circuit 11 according to the values ​​of the light parameters and temperature measured by the sensing module 13, so that the values ​​of the parameters and the temperature measured by the sen...

Abstract

The invention relates to an intelligent light-emitting diode illuminating system, which comprises at least one light-emitting diode module, a sensing module, a control circuit and a drive circuit. The sensing module can automatically detect light ray related parameters of brightness, chroma or color temperature, and the like in an illuminating environment and can automatically detect the environment temperature. The control circuit can adjust the drive current output by the drive circuit according to the numerical values of the parameters measured by the sensing module to finally make the numerical values of the parameters measured by the sensing module accord with a preset standard in the control circuit. The illuminating system additionally comprises an outer housing which can homogenize light rays output by the light-emitting diode module or has light guide effect of guiding the light rays to most of the surface of the outer housing. Besides, the signal communication between the control circuit and the drive circuit can be achieved through wireless transmission.

Description

technical field [0001] The invention relates to an intelligent light-emitting diode lighting system, in particular to a lighting system capable of sensing light and temperature conditions in the environment and automatically adjusting light output conditions. Background technique [0002] Due to low power consumption, small size and long service life, light-emitting diode components are currently widely used in applications such as indicator lights of household appliances, backlights of liquid crystal displays, graphic display screens, and third brake lights of automobiles. In recent years, due to the successful development of light-emitting diode materials such as aluminum gallium indium phosphide (AlGaInP) and aluminum gallium indium nitride (AlGaInN), light-emitting diode components can replace traditional incandescent bulbs in many applications. [0003] At present, the LED lighting device uses a transformer to convert indoor alternating current into low-voltage direct c...
