Title: High-pressure discharge lamp
Inventor: SHIMIZU KENICHI
IPC: H01J61/42
Filed: 1983-02-04
Abstract: PURPOSE:To provide, in a high-pressure discharge lamp, high adhesive strength of the phosphor coating and enhanced luminous flux, by spreading the phosphor by an electrostatic coating method on the interior of the external glass bulb in a number of layers in such a way that the layer closer to the external glass bulb is of smaller grain sides of the phosphor and the layer closer to the illuminating tube is of larger grain sides. CONSTITUTION:Phosphor coating layers 7, 8 are formed on the internal wall of the external bulb 1 by an electrostatic coating method. The phosphor coating layers 7, 8 are formed of two layers; relatively smaller grain sides of the phosphor are included in the layer closer to the internal wall of the external bulb 1 and relatively larger grain sides are included in the layer closer to the illuminating tube 4. By such an arrangement, the phosphor strongly adheres to the internal wall of the external bulb, and high luminous flux is attained since the ultraviolet rays radiated by the electric discharging in the high-pressure illuminating tube 4 together with visible rays are readily and effectively converted into visible rays at the phosphor coating layer 8 of the relatively larger grain sides of the phosphor, and the phosphor coating is strongly adhered to the wall surface and will not peel off since the phosphor coating layer 7 of the relatively smaller grain sides is intervened between the layer 8 and the internal wall of the external bulb, and thus the lamp provides desired performance.
