Problems solved by technology

This is because of their low light transmission (8-15% of emitted energy) and therefore do not provide usable products for signaling, especially automotive signaling

Embodiment Construction

[0064] figure 1 Shown is a bulb 1 comprising a spindle-shaped glass blank 2 based on a glass of the SiO2-R2O-RO type, where R2 is an alkali metal element and RO is an alkaline earth metal element.

[0065] This blank is red. It is obtained from a vitrifiable mixture formed of sand from the Fontainebleau (France) region, for example containing, for 100% by weight of the mixture, 0.5% by weight of copper, 1% by weight of tin, 2% by weight of lanthanide oxides and / or 0.2% by weight silver nitrate.

[0066] The bulb 1 comprises, in a manner known per se, a bulb cap 3 connected to an electrical supply system, and a filament 4 .

[0067] Thus, according to the invention, by using the vitrifiable mixtures described above, while controlling the melting parameters (temperature and residence time in the furnace) known per se, the redox properties of the glass bath optimized with suitable ratios and the use of suitable The cooling method, as will be described more precisely below, ma...

Abstract

The invention relates to a bulk-tinted red glass formed from a glass batch based on a soda-lime-silica composition, to a process for manufacturing red glass and to a bulb obtained from a blank or a tube manufactured with such a glass. The batch comprises, per 100% by weight of the batch, 0.1 to 1% by weight of copper, 0.2 to 2% by weight of tin and 0.01 to 2.5% by weight of oxide of the lanthanide group and / or 0.01 to 0.5% by weight of silver in silver oxide or nitrate form.

Description

technical field [0001] The present invention relates to a bulk tinted red glass formed from a vitrifiable mixture based on a silicon-sodium-calcium composition. [0002] The invention also relates to a process for the production of red glass, the bulbs and tubes obtained using this glass. [0003] Although not exclusive, the invention finds a particularly important use in automotive signal lights (tail lights, brake lights). Background technique [0004] “Red” is understood to mean the red coloring registered in the field, for example as defined by international standards, in particular in the reference system of the International Commission on Illumination known under the name CIE 1931 . [0005] In Europe, the color space defined by the regulation ECE corresponds to a trapezoidal region whose X and Y coordinates are as follows: [0006] A(0.657-0.335) [0007] B(0.665-0.335) [0008] C(0.735-0.265) [0009] D (0.730-0.263). [0010] These points define the area dedic...
