橡胶车间高温、有异味、溶剂挥发多，属于潜在爆炸性环境；普通灯具既怕高温又怕溶剂腐蚀，还可能是点火源。
一般作业区 300lx、检验区 500lx，溶剂与粉尘爆炸性区域按 Exd IIB T4 以上选型，灯具 IP65、耐高温，显色 Ra≥80 便于辨别胶料颜色与缺陷。
曦韵为橡胶厂选用防爆耐温灯具与密封接线，硫化与检验工位单独加强照明，既守住安全底线，又让胶料色差与气泡一眼可见。
Rubber shops are hot, odorous and rich in solvent vapour, a potentially explosive atmosphere; ordinary fixtures fear both heat and solvent and can themselves be ignition sources.
General work 300 lx, inspection 500 lx; solvent and dust hazard zones Exd IIB T4 or better, IP65 and heat-tolerant, Ra>=80 to read compound colour and defects.
Xiyun specifies explosion-proof heat-rated fixtures with sealed wiring, and accents curing and inspection stations so colour shifts and bubbles show at a glance.
