Specific embodiment
Specific implementation of the patent mode is described in detail with reference to the accompanying drawing, it should be pointed out that the specific reality
Applying mode is only the citing to this patent optimal technical scheme, can not be interpreted as the limitation to the scope of this patent.
As shown in Figure 1, present embodiment provides a kind of adjustable uitraviolet intensity for refrigerator fresh-keeping chamber
Chlorination equipment, described device include: switch timer 2, band PWM dimming power source converter 3, UVC-LED array 5.
As shown in Figure 1, in this embodiment, the input terminal 1 for switching timer 2 is defeated with the refrigerator
Enter power supply connection, for obtaining electric power from the input power of the refrigerator, the switch timer has switch and timing
Function, specific structure can complete using switch counts device in the prior art, and the input power of refrigerator is input to
The switch timer starts and stops and controls sterilizing unit by the related sterilizing unit of the switch timer control
Working time or dwell time, this is to provide the foundation according to needing to provide sterilizing function.In addition, the switch timer is also
It can be connected with the sensor or switch being arranged in refrigerator doors, when the refrigerator doors are opened, the switch timer is opened
Shutdown is opened, thus can be to avoid the radiation injury when operator opens refrigerator doors by ultraviolet light.
The band PWM dimming power source converter 3 is connected with the output end of the switch timer, passes through the band PWM tune
Photoelectricity source converter 3 controls the power of the work of UVC-LED array, such as shown in Fig. 2, when low intensity ultraviolet power output
When, it is to be spaced biggish interruption waveform that the PWM dimming power source converter 3, which controls its power waveform,；When the ultraviolet function of moderate strength
When rate exports, it is to be spaced lesser interruption waveform that the PWM dimming power source converter 3, which controls its power waveform,；When high-intensitive purple
When external power exports, it is continual waveform that the PWM dimming power source converter 3, which controls its power waveform,.Pass through output in this way
