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

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 [mu]m to 1.9 [mu]m, 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 [mu]m to 2.8 [mu]m or from 1 [mu]m to 4 [mu]m, 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 [mu]m to 4 [mu]m. 在不同的实施例中提供低压放电灯(1)。所述低压放电灯有放电容器(2)和涂层结构(7)。所述涂层结构形成在放电容器(2)的内侧上。所述涂层结构(7)具有第荧光材料颗粒(34)，所述第荧光材料颗粒具有至少种发红光的荧光材料并且其平均颗粒尺寸在0.5μm至1.9μm的范围内，第二荧光材料颗粒(36)，所述第二荧光材料颗粒具有至少种发绿光的荧光材料并且其平均颗粒尺寸在0.6μm至2.8μm或1μm至4μ
