Light source and method for mechanically stabilizing the filament or electrode of a light source

Abstract

A video recording and reproducing apparatus and a method having a data recovery function, wherein the method includes recording a temporary recording information file concerned with recovery information while recording data, file system and recording information on a disc. The temporary recording information file is read upon disc reproduction to conduct a recovery operation. The apparatus includes a recording device recording a temporary recording information file concerned with recovery information while recording data, file system and recording information on a disc. A controller controls the video recording and reproducing apparatus so as to read the temporary recording information file upon reproducing data on the disc to conduct a recovery operation. The temporary recording information file is recorded on a temporary recording information file area arbitrarily defined on the disc. The temporary recording information file area has a temporary storage location at a section (innermost circumference portion, middle portion or outermost circumference portion of the disc) in very close proximity to a position where data is recorded on the disc. Audio / video is recorded and at the same time, file system information and reproduced recording information are recorded on the disc by use of a remaining time during recording without using memory recording power breakdown recovery information, so that recorded video is recovered even after power breakdown without any dedicated operation, reducing design cost and simplifying circuit construction.

Description

technical field [0001] The invention relates to a light source with a heatable filament or electrode arranged in a bulb or vacuum tube. The invention also relates to a method for the mechanical stabilization of a filament or electrode of a light source. Background of the invention [0002] Light sources of the type described above have been known for a long time and exist in various embodiments. In particular, filament lamps, halogen lamps and low-voltage or high-voltage discharge lamps as well as electronic light-emitting diodes are known. For example in luminous tubes, the light source is based on thermionic emission, gas shock excitation or a luminescence effect. [0003] In addition, for different application fields, special independent light sources are usually produced at present, which are especially suitable for specific applications. For example, in individual cases, specialized filaments such as tantalum carbide filaments may be used for light sources requiring ...

AI Technical Summary

Problems solved by technology

[0004] A disadvantage of many specialized filament or electrode materials is that, while these materials can meet the required light output, they are often susceptible to shock and vibration, often resulting in filament or electrode fracture

Light sources equipped with known filaments or electrodes are not suitable for mass production or use in various industries
