Description

  The present invention relates to a lighting device having a life notification function, and a lighting fixture using the lighting device.

  Conventional lighting fixtures using FL, HID, etc. have a long life for the user, such as when the lamp reaches the end of its service life, it will not illuminate, it will be difficult to illuminate, or the conventional brightness will not be achieved. It will be easy to find out and the lamp will be replaced. On the other hand, the luminaire itself has a useful life, that is, a so-called life. The life of the luminaire itself appears due to fatigue of metal parts, oxidation, deterioration of plastic parts, discoloration, breakage, deterioration of parts constituting the ballast, reduction of insulation resistance, and the like. Nevertheless, when the lamp is lit normally, the user generally keeps using it without noticing the life of the lighting fixture itself.

  When a lighting fixture is used beyond its lifetime, not only the proper performance as a lighting fixture cannot be obtained, but there is a risk that the fixture will be damaged, dropped, ignited, etc. depending on the deteriorated part. In general electronic devices such as TVs, changes from the beginning can be seen relatively easily due to various deteriorations, and TV performance such as image blurring, color changes, and sound malfunctions. It is easy to guess that. On the other hand, since the main function of the luminaire is to properly shine the lamp and illuminate the object, the degree of deterioration of the luminaire is difficult to understand. For this reason, it is very difficult for the user to understand the deterioration of the device, and a lighting device having a useful life of, for example, 10 years may continue to be used for more than 10 years, and in some cases for more than several tens of years.

As a means for determining the life of a lighting fixture, there is known a means in which the lighting time of a discharge lamp is integrated and the life is determined by exceeding a predetermined time (for example, refer to Patent Document 1). Patent Document 1 also discloses a concept of correcting the integrated count value in consideration of the temperature of a component with a limited life. However, the lifespan of the luminaire varies greatly depending on the use environment, and as described in Patent Document 1, it cannot be said that the accurate lifespan is determined simply by counting the cumulative lighting time. In other words, if the life of the appliance is determined only by the cumulative lighting time due to the difference in the usage environment, etc., the component with a limited service life may fail before the appliance is determined to be at the end of its life, or conversely, the life of the appliance is not reached. Therefore, there is a possibility that the life determination accuracy cannot be maintained. Further, Patent Document 1 does not specifically disclose the notification method after the life determination.
