For example, when the current intensity of the LED device 120 is 60 mA, the intensity of the external power source is much larger than the current required by the LED lamp module, So that the intensity of the current is controlled so as to emit light.

That is, the LED device 120 mounted on the LED lamp module 100 is mounted with different intensity of light emission according to the characteristics of the LED lamp module 100.

However, since the intensity of the external power supplied to the LED lamp module 100 is constant, when the intensity of the current with the mounted LED module 120 is different according to the characteristics of the LED lamp module 100, I will not.

At this time, the current controller 130 adjusts the intensity of the current with the current corresponding to the LED element 120 so that the LED element 120 can emit light.
