Indoor lighting design method

Abstract

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.

Description

technical field [0001] The invention relates to an illumination design method of indoor lighting, in particular to an indoor lighting design method considering light source attenuation. Background technique [0002] Illumination calculation includes the calculation of brightness calculation, glare calculation, illuminance calculation and other effects, which is the basis of lighting design. The calculation of glare can be ignored when the indoor lamps are evenly arranged. In general, the lighting environment is relatively stable, that is, the reflection characteristics of the illuminated surfaces such as walls, ceilings, and floors remain unchanged, and the reflections in most places are mostly diffuse. Therefore, the brightness of the lighting depends on the luminous flux projected by the incident light on the unit area, that is, the illuminance. Because the calculation and measurement of illuminance are relatively simple, the current international and domestic lighting st...

Problems solved by technology

The luminous flux of most light sources attenuates more in the early stage of ignition. As the ignition time increases, the attenuation gradually decreases, but it is still attenuating, resulting in the luminous flux emitted by electric light source lamps after working for a period of time. Luminous flux, resulting in a decrease in the indoor illuminance value, which affects the actual indoor lighting effect

[0004] When using the conventional illuminance calculation method for lighting design, the attenuation of the light source is not considered. However, as the lighting time increases, the attenuation of the light source will cause the actual indoor illuminance value to decrease, and the lighting effect will also deteriorate, which may lead to the actual lighting situation.
