| 摘要 |
Described herein is an apparatus which is, under a range of atmospheric conditions, capable of maintaining the emission of light at a point remote from a light source. Notably, the apparatus is able to heat and distribute a fluid, and by doing so, prevents condensation and ice from forming which could hamper the emission of light. The apparatus comprises a light source and a light emitter, with a light conduit and a fluid conduit running between. A method for using such apparatus is also described.
