Emergency Lighting
Battery-Backed Emergency Light Fixtures
Battery-backed emergency light fixtures providing illumination during power failures or evacuations.
Purpose
Battery-backed emergency light fixtures providing illumination during power failures or evacuations.
Context
Child of L2-HAB-LIGHT within the Lunar Ark system
Principles
- ▸Local battery backup (~30 min)
- ▸Photoluminescent path markers for absolute darkness
- ▸Auto-activation on main power loss
- ▸Self-test cycle weekly
- ▸Long-life LiFePO4 batteries
Typical implementations
- ▸NFPA 101 emergency lighting standards
- ▸Aerospace emergency illumination
- ▸Industrial safety lighting
Lunar considerations
- ▸Independent of L3-PDM-BUS-MAIN
- ▸Long-life batteries with self-test
- ▸Photoluminescent for absolute reliability
