| This paper is mainly based on the design of RGB LED lighting system,combined with the principle of light source and the principle of three primary colors,to design colorful light source.At present,the protection of the eyesight LED is not really the function of protecting eyes,its light source is far from the effect of natural sunlight,this paper uses the relevant data of integrating sphere to adjust the color,and finally get the effect of natural light.At the same time,according to the shortage of LED lamp in circuit detection,this paper puts forward the LED automatic detection device,which is a whole with LED,used to monitor short circuit and local open circuit in the circuit.Since the LED lamps are arranged by the diode array,when the LED lamps are damaged,the self-check device judges whether need to replace the lamp,or continue to use,the device fundamentally avoids the energy loss caused by short circuit,when the local open circuit,the self-check device achieves the current balance by adjusting its resistance.This paper first introduces the LED and the subsequent development of three primary colors LED,through the introduction of light characteristics,introduces the principle of three primary colors,according to the colorimetric principle and three primary colors principle of the light source,the possibility of mixing white light source is discussed,based on the existing three primary colors LED.The hardware circuit of this design mainly includes microprocessor control circuit,LED constant current drive and other parts.At the same time,for the LED lamp increase detection circuit,real-time monitoring circuit current,thus effectively avoid the waste of resources caused by short circuit LED lamps. |
