LOW-PRESSURE DISCHARGE LAMP WITH FLUORESCENT PARTICLES HAVING A SMALL PARTICLE SIZE

摘要

In different embodiments, a low-pressure discharge lamp (1) is provided. The low-pressure discharge lamp has a discharge vessel (2) and a coating structure (7). The coating structure is formed on an inner face of the discharge vessel (2). The coating structure (7) has first fluorescent particles (34) which have at least one fluorescent substance that emits red light and the average particle size of which ranges from 0.5 μm to 1.9 μm, second fluorescent particles (36) which have at least one fluorescent substance that emits green light and the average particle size of which ranges from 0.6 μm to 2.8 μm or from 1 μm to 4 μm, and third fluorescent particles (38) which have at least one fluorescent substance that emits blue light and the average particle size of which ranges from 1 μm to 4 μm.
