WebApr 12, 2024 · Here, we propose and experimentally realize a photon-recycling incandescent lighting device (PRILD) with a luminous efficacy of 173.6 lumens per watt (efficiency of 25.4%) at a power density of 277 watts per square centimeter, a color rendering index (CRI) of 96, and a LT70-rated lifetime of >60,000 hours. WebEvery continuous action of the additive group R2 on the sphere S2 admits a fixed point. Corollary. The same fact is true for the projective plane P2, instead ofS2. Theorem B. Let X, Y be vector fields of class C, k = l, on the sphere S2, with [X, Y] = 0. There exists a point pES2 such that X(p) = Y(p) = 0. Corollary.
