Low-pressure discharge lamp with fluorescent particles having a small particle size

Low-pressure discharge lamp, with a discharge vessel and a coating structure formed on an inside of the discharge vessel, the coating structure comprising:

• first fluorescent particles which have a least one fluorescent substance emitting red light and the mean particle size of which lies in a range from 0.5 μm to 1.9 μm,
• second fluorescent particles which have at least one fluorescent substance emitting green light and the mean particle size of which lies in a range from 0.6 μm to 2.8 μm or from 1 μm to 4 μm, and
• third fluorescent particles which have at least one fluorescent substance emitting blue light and the mean particle size of which lies in a range from 1 μm to 4 μm;
• wherein the fluorescent substances each comprise activators and host lattices doped with the activators, wherein
• a proportion of the activators in the fluorescent substance emitting green light lies in the range from 6.5 mol % to 16 mol % or from 20 mol % to 50 mol %,
• a proportion of the activators in the fluorescent substance emitting red light lies in the range from 2.3 mol % to 5.5 mol %, and/or
• a proportion of the activators in the fluorescent substance emitting blue light lies in the range from 3.0 mol % to 11.0 mol %.
