Abstract

The invention provides a light apparatus of a luminous component and the main light source is light-extinguished, in order to prevent influence of the main light source and surrounding circuits thereof when main light source abnormality detection unit detects abnormality of main light source, thereby raising security, reliability, and users' and maintenance personnel's use convenience. The lamp apparatus has a main light-source unit lightened and supplied by a first power-supply unit, a constant current control unit that supplies constant current to light emitting elements (LED-1-LED-n). Main-control unit controls lighting of main light source for specific time period, when electric power which restarts the main light source is supplied.

Description

technical field [0001] The invention relates to a light emitting element illuminating lamp device comprising a main light source having a light emitting element. Background technique [0002] With the development of light-emitting elements (such as semiconductor light-emitting diodes) technology, lighting devices that use light-emitting elements instead of light bulbs or fluorescent lamps have been proposed. However, even with light-emitting elements, abnormalities inevitably occur. In addition, since a large number of light-emitting elements are installed, it is necessary to take appropriate countermeasures against occurrence of abnormalities. [0003] In the prior art, there is a white LED driving circuit for lighting, which has the column (or columns) of white LEDs through which the abnormal current flows when an abnormal current (current greater than or equal to a predetermined value) is detected. Such a function of current (for example, refer to Patent Document 1). ...
