Pwm control one kind of synthetic broad band light source apparatus

One kind of PWM control synthetic broad-band light source apparatus, which relates to the synthesis of a broad band light source technical field, the power module, respectively a communication module, a control module, a drive module, LED synthetic broad band light source is connected, for each supply module, a control module respectively connected to the communication module, a drive module, the drive module and the LED synthetic broad-band light source is connected, the communication module receives an external control signal to the control module, the control module take the appropriate driving method driving in accordance with the received instruction from the control drive module one or more LED a light source, thereby changing the spectral distribution and the spectral width; it through the MODBUS? RTU bus connected to the controller, may vary in claim spectral distribution characteristic, the adjustable power spectral density to suit different applications, can be achieved spectral segment is electrically controlled to satisfy the monolithic grating without spectral overlapping signals dispersive imaging; good controllability, low power consumption, long life, good stability, no warm-up time; using a coupling lens and an optical fiber as a conductor so that a high coupling efficiency of the entire optical path loss is small.
