Indoor lighting design method

The invention discloses an indoor lighting design method. The conventional illuminance calculation method does not consider the situation of lamp source attenuation when performing lighting design, and the lamp source attenuation occurs with the increase of lamp use time and results in the reduction of the actual indoor illuminance value, which is inconsistent with the initially calculated illuminance value. According to the method, the lamp source attenuation condition of the lamp is measured and the lamp attenuation correction coefficient K (t) of the lamp varying with the use time is established; then the existing lighting analysis software is utilized to perform lighting simulation calculation to obtain the indoor illuminance value E (0) at the moment; and finally the lamp source attenuates after the lamp is used and the indoor illuminance can be corrected by using the lamp attenuation correction coefficient K (t). The actual indoor illuminance value E (t) can be calculated by using the following formula when the lamp is used for illumination after t time: E (t) = E (0) * K (t). The attenuation problem of the lamp source is considered and the indoor illuminance requirement within the set time can be guaranteed.
