Abstract：The improvement of the overall luminous efficacy of lamps has not brought about a corresponding increase in the energy-saving amount of functional lighting.Excessive ambient brightness is not conducive to people's health needs and will instead bring more light pollution to the city.Although reducing unnecessary ambient lighting in the light distribution design will lower the overall luminous efficacy and challenge the general perception that"the higher the luminous efficacy of lamps,the better",it will purify the nighttime light environment,which is more conducive to energy conservation.Controlling spill light is a necessary means to promote the healthy development of functional lighting and is also an inevitable choice to achieve further energy-saving LED lighting.
