Abstract: A high-pressure metal-vapor discharge lamp is formed by enclosing scandium-halide, preferably scandium-iodide (ScI3) in the amount of 1.80 X 10 7 to 9.27 X 10 6 gram mol/cc of confined gas, and at least 3.1 times said halide quantity in atomic ratio of free (metal) scandium, together with some mercury as a buffer gas, inside a translucent alumina tube. Such discharge lamp can maintain a luminous efficiency of over 70 lumen/Watt and a general color-rendering index of over 70 for a period in excess of 6,000 hours, and thus, it is very useful as a general lighting source.

Optionally 12#z#16 and the vanadate phosphor content is 20 to 95% by wt. The blue green phosphor emitting at 436 to 546 nm. produces the desired colour rendition at the required colour temperatures. Variation of the x/y ratio changes the colour temperature components at 450 nm. and 5/5 nm. of the Eu 2+ and Mn 2+ respectively. Emission characteristics for specified phosphors are disclosed (Fig. 2, not shown), variations with temperature discussed w.r.t. Fig. 3 (not shown), with Al content (Fig. 5, not shown), and diffraction analyses discussed w.r.t. Fig. 6 (not shown) indicate a single phase, α-Al 2 O 3 phase or #-Al 2 O 3 phase according to the z value. Colour temperature variations with relative concentrations are disclosed for specific phosphors (Fig. 7, not shown), and phosphor coverage/cm. 2 given.

Abstract: PURPOSE:To improve the luminous flux degradation during life by forming, on a glass bulb inner surface, a protective film mainly containing a granular rutile titanium dioxide fine particle the surface of which is coated with fine powder of silicon oxide. CONSTITUTION:On the inner surface of a glass bulb 1, a protective film 2 consisting of a granular rutile titanium dioxide fine particle having a recessed part or through hole, the surface of which is coated with fine powder of silicon oxide and aluminium oxide, is formed. On the film 2, a phosphor layer 3 is formed. Thus, dispersing property in suspension regulation is enhanced, and the film surface of the film 2 is made satisfactory. The film 2 never cause the crack or dropping out of the layer 3 in various heating works in the manufacturing process of a fluorescent lamp. Thus, the characteristic in that luminous flux degradation is minimized through the life can be provided. Since the film 2 has no bad effect also on heating works and exhausting process, further, the luminous flux reduction can be minimized through the life of the fluorescent lamp.
