When it comes to the effective sterilization range, it should also be based on the concept of dosage. Unfortunately, for a point emitting light source, the intensity distribution on the illuminated surface of the plane is similar to a Gaussian distribution in the shape of a mountain peak, with several times the intensity difference at the center and edges. If the customer is asking this question rigorously, we should conduct more accurate optical simulations to calculate the intensity distribution at various locations on the plane. Simulation may not be precise enough, but it provides a qualitative reference for our scheme design. The irradiation surface is uneven, and the simulation tool can calculate it relatively clearly
When defining the luminous angle of a lamp bead, the angle is half of the peak intensity. It is suggested that we also define the effective range as half of the peak intensity on the plane during the scheme design, and calculate the dose based on the half height position
Due to the spherical shape of LED light, there is a significant difference in the uniformity of intensity distribution between areas closer and farther away. At 20cm, the effective irradiation range accounts for a larger proportion of the entire illuminated surface
