Abstract: A light emitting unit comprises a light emitting element, a light emitting element substrate for mounting the light emitting element, a light emitting element substrate frame member provided with a window for exposing the light emitting element, and an electrode for supplying electricity to the light emitting element, wherein the light emitting element substrate is a metal and the light emitting element is mounted directly on the light emitting element substrate. The light emitting unit is also characterized in that the light emitting element substrate is a metal, a metal oxide film is provided on the light emitting element substrate, and the light emitting element is mounted on the electrode formed on the metal oxide film.

Abstract: When heating and bending glass sheets in a furnace, it has been found to be desirable to raise the glass sheets towards the furnace heat sources to increase obtainable temperature differentials and reduce heating power. An apparatus for bending the glass sheets includes an elongate furnace divided along its length into a plurality of heating zones, each heating zone having an upper part. A plurality of heat sources are arranged in the upper part of such heating zone and a plurality of carriages are arranged in succession along the length of the furnace below the furnace heat sources. A drive device propels the carriages through the zones of the furnace in intermittent steps, and a mould lift raises the bending mould towards the furnace heat sources. The bent glass sheet may be used in the manufacture of a vehicle glazing.

Abstract: Glass sheets are press bent and tempered, especially for use as glazings in vehicles. Such glazings are required to be accurately bent to a complex shape while meeting high standards of optical quality and fracture safety at an acceptable cost. A method of bending and tempering a glass sheet is provided comprising heating the sheet in a furnace, including heating at least one portion of the sheet to a higher temperature than another portion, conveying the sheet out of the furnace and into a press bending station, shaping the sheet by pressing it between opposed complementary upper and lower press members, at least one of the members being internally heated, transferring the bent glass sheet onto a shuttle carrier ring conforming to the periphery of the sheet, and tempering the sheet while supported on the carrier ring. A corresponding apparatus is also described.
