LED street lights manufacturers for Older People and People with Visual Impairment

  Recent years, CIE issued a new technology report — Lighting for Older People and People with Visual Impairment in Buildings（CIE—277），making analysis of how LED street lights manufacturers exerts bad influence on visual function(including visual acuity, contrast sensitivity, view, color vision). And it provided some lighting design plans for the aged, low-vision people in terms of office and the public lighting environment.

  When a person age goes beyond 45, internal light scattering rising up and spatial contrast sensitivity and retinal luminance down, visions will lower down by the time. Over 285,000,000 people suffers visual impairment across the globe in 2017, and which is severer with the more and more serious in aging problem, according to a study from WHO. This is a problem we can’t ignore.

  Above is involved with different nation aging tendency

  Among the previous reports, something about how lighting impairs people’s vision was listed. And they provided some pieces of suggestion. However, this report improves these plans connecting with current social circumstance based on current researches.

a.Lower seniors ages standards from 65 to 50, and increase some lighting requirements in office and other public areas.
b.Analyze how bad lighting exerts negative influence on seniors’ vision and offer some design advice mainly for seniors and low eyesight.
c.Analyze some design methods in detailed examples.

According to this report, the high of people age, the high rate of suffering from this impairment. Therefore, in order to protect the aged eyesight and health from these bad LED street lights manufacturers, something should be done about paying more attention to the lighting design.
