体检中心照明影响的是'检查精度'：抽血台、视力表、皮肤观察，每项检查对光的要求不同，错一个环节数据就不可信。
抽血操作面500lx且Ra≥90（观察血管色泽）、一般诊室300lx（GB50034）；视力检查区照度按视力表国家标准独立恒定，不受相邻区域调光影响。
我们的体检中心照明方案与设备科联合验收，每间检查室照度留档，审核检查质量时数据可追溯。
Checkup-centre lighting affects diagnostic precision: blood draws, vision charts, skin observation — each exam has its own light needs, and one wrong link corrupts the data.
Blood-draw task 500 lx at Ra≥90 (vein tone), general consults 300 lx (GB50034); vision-chart areas on an independent constant circuit per national standard, immune to neighbouring dimming.
Our checkup-centre packages are jointly commissioned with biomedical engineering, illuminance archived per room for traceable quality audits.
