And (4) according to the analysis and comparison results, if the lamp type selection or lamp arrangement exceeds the national standard value, performing illumination measurement, calculation and analysis again.
The lamp type selection comprises the selection of the power, the light-emitting angle and the light distribution density of the lamp.
In a specific embodiment, taking a building as an example, referring to fig. 2 as a building model, referring to fig. 3, lamps are uniformly arranged on a certain area of the outer vertical surface of the building 10 to form a light-emitting surface 11, which is a light-emitting surface 11 parallel to the building 10 and attached to the outer vertical surface of the building 10, referring to fig. 4 as a calculated surface illuminance analysis graph (after optimization) parallel to the light-emitting surface of the building and about 20 meters away from the light-emitting surface, referring to fig. 5 as a calculated surface illuminance analysis graph (after optimization) parallel to the light-emitting surface of the building and about 70 meters away from the light-emitting surface, referring to fig. 6 as a calculated surface illuminance analysis graph (after optimization) perpendicular to the light-emitting surface of the building.
