Improvement in thermal damage
It can irradiate heat-sensitive objects at a very close distance since heat ray (infrared ray) is not contained in the light.
Lower running cost
Longer LED life reduces lamp replacement cost and man-hours. It also reduces management man-hours.
Good applicability and stability
LED has a good on/off response. It can control irradiation to be suited for objects.
