Speaking of effective sterilization range, It should also be based on the concept of dosage. Unfortunately, For a point emitting light source, The intensity distribution of the illuminated surface on the plane is a peak shape that approximates the Gaussian distribution, There can be several times the difference in strength between the center and the edge. If the customer is asking this question rigorously, We should conduct more accurate optical simulations, Calculate the intensity distribution at various locations on the plane. Simulation may not be accurate enough, But it provides a qualitative reference for our scheme design. Uneven irradiation surface, Simulation tools can calculate more clearly.

When defining the luminous angle of the lamp bead, It's an angle of half the peak intensity. Suggest that we also define the position where half of the peak intensity is on the plane as the effective range in the design of the scheme, At the same time, the calculation of dosage is also based on the half height position.

because LED The reason why the light type is spherical like, Close and far places, There are significant differences in the uniformity of intensity distribution. at 20cm place, The effective irradiation range accounts for a larger proportion of the entire irradiated surface.
