Source component carries out light modulation toning.For the light source device used in Fig. 3 for light emitting diode, this is only schematical, light source device
It can also be other kinds of luminescent device such as incandescent lamp etc., the utility model embodiment is not specifically limited this.
Referring to Fig. 1, in one embodiment of the utility model, when PWM generator 121 is without external controller shown in Fig. 2
When 13, PWM generator 121 itself that power supply module 12 carries can to the pwm signal that die set 11 is sent duty cycle it
With no more than 100%.Also, referring to Fig. 3 and Fig. 4, when 121 external controller 13 of PWM generator, controller 13 can control
The PWM generator 121 of power supply module 12 to the multichannel module of die set 11 send corresponding pwm signal (such as PWM1,
PWM2 ... PWMn), and the sum of duty cycle for making pwm signal is no more than 100%.It can so be sent using PWM generator 121
Pwm signal Duty ratio control die set 11 output general power without departing from predetermined power, that is, ensure die set 11 not
It is present with overpower output.For every road module, the duty cycle for the pwm signal that PWM generator 121 is sent to every road module
Can be any numerical value in 0%~100%.Wherein, the duty cycle of pwm signal refers to high level institute in a pulse period
Account for the ratio of whole cycle.

N/mono- that the output power for not controlling N roads module Zhong Mei roads module is P, and the output general power of die set 11 is
Full power P.
Mode two, controller 13 control pwm signal that PWM generator 121 sent to every road module using control signal
In duty cycle, the duty cycle at least there are the pwm signal of two-way module is unequal.
For example, the multichannel module in die set 11 works with two-way module, controller 13 controls power supply module 12
The duty cycle that PWM generator 121 sends pwm signal respectively to two-way module can be 10% and 90% or 30% and 70%,
Or 80% and 20% etc..But it cannot be 60% and 50%, that is, be sent to the sum of duty cycle of two-way module more than 100%
Situation.
Referring to Fig. 1 and Fig. 2, in one embodiment of the utility model, when the multichannel module in die set 11 only has all the way
When module works, no matter PWM generator 121 whether external controller 13, PWM generator 121 sends pwm signal to the road module
Duty cycle all be 1.After it is 1 pwm signal that die set 11, which receives the duty cycle that PWM generator 121 sends, this is utilized
The output power of the Duty ratio control of the pwm signal road module is P, and the output general power of die set 11 is also P.
With continued reference to Fig. 3 and Fig. 4, in one embodiment of the utility model, when outside the PWM generator 121 of power supply module 12
When connecing controller 13, control port (not shown) is provided on controller 13, is provided on power supply module 12 and control terminal
The corresponding first receiver port (not shown) of mouth, and the first receiver port is connected with PWM generator 121.When
After controller 13 sends control signal using control port, PWM generator 121 receives the control using the first receiver port
Signal.
In another embodiment of the utility model, power supply module 12 have signal sending end mouth, and signal sending end mouth with
PWM generator 121 is connected (not shown), and die set 11 includes secondary signal corresponding with signal sending end mouth and receives
Port (not shown).When the pwm signal that power supply module 12 is sent PWM generator 121 by signal sending end mouth is sent
During to die set 11, die set 11 receives the pwm signal, and accounting for using pwm signal using secondary signal receiving port
Output power of the sky than controlling multichannel module that die set 11 includes respectively, so that the output general power of die set 11 is pre-
If power.
With continued reference to Fig. 3 and Fig. 4, in one embodiment of the utility model, die set 11 and power supply module 12 are respectively provided with
Anode LED+ and negative terminal LED-.If the multichannel module that die set 11 includes is to be connected in parallel, then is connected in multichannel modules in parallel
