    • The light-scattering bulb (1) is provided for a semiconductor retrofit lamp (R1), said bulb (1) having a basic hollow cylindrical shape. The bulb (1) has a main part (2) made of glass, and the main part (2) is coated with a light-scattering layer (4). The light-scattering layer (4) has scattering particles (P1, P2) distributed in a translucent base material. The base material is an inorganic lead-free base material (G), and the scattering particles (P1, P2) are inorganic scattering particles. A method is used to produce a bulb (1), said method having at least the following steps: coating the main part (2) made of glass with a coating agent, which is a starting material for producing the light-scattering layer (4) of the bulb (1); and drying some sections of the coating agent and baking the layer so as to convert same into the light-scattering layer (4), said drying process being carried out in a staggered manner in the flow direction of the coating agent. The invention can be used in particular for semiconductor retrofit lamps for gas discharge tubes and linear lamps.
    • 光散射灯泡(1)设置用于半导体改装灯(R1),所述灯泡(1)具有基本的中空圆柱形状。 灯泡(1)具有由玻璃制成的主要部分(2),主体部分(2)涂覆有光散射层(4)。 光散射层(4)具有分散在半透明基材中的散射粒子(P1,P2)。 基材为无机无铅基材(G),散射粒子(P1,P2)为无机散射粒子。 一种用于制造灯泡(1)的方法,所述方法至少具有以下步骤:用作为制造光散射层(4)的原料的涂布剂涂覆由玻璃制成的主体部分(2) )灯泡(1); 并干燥涂层剂的一些部分并烘烤该层以便将其转化成光散射层(4),所述干燥过程在涂布剂的流动方向上以交错的方式进行。 本发明可用于气体放电管和线性灯的半导体改装灯。
